Everything You Need to Know About NSN 5960-00-185-9974 Electron Tube

 The NSN (National Stock Number) 5960-00-185-9974 refers to an Electron Tube—specifically part numbers 145007-1 and SFD267. Below is a comprehensive overview of this item, its features, manufacturers, and why it remains important in electronics and military applications. The information is drawn from ChipsOnSale.com, which provides detailed NSN sourcing and electronic component procurement services.

What is 5960-00-185-9974?

  • NSN: 5960-00-185-9974

  • FSC / NIIN: It falls under FSC 5960 (Electron Tubes) with the NIIN 001859974.

  • Item Name: Electron Tube.

This electron tube is a military spec / industrial part, used in systems requiring vacuum tubes or related tube technologies.

Special Features & Specifications

Based on available manufacturer and NSN data:

  • Envelope Material: Metal. This suggests a rugged, durable construction, suited to harsh environments.

  • Manufacturing Class: Cross Field Amplifier. This indicates that the tube is designed to work with cross-field amplifier circuits, likely for high power or RF (radio frequency) amplification applications.

These characteristics make 5960-00-185-9974 suitable for applications where reliability and performance are critical—especially where solid-state devices may not suffice or where legacy systems are involved.

Manufacturing & Part Numbers

This tube is known by two main Manufacturing Part Numbers (MPNs) or SKUs:

  • 145007-1, with Cage Code 24930, manufactured by ITT Corporation.

  • SFD267, with Cage Code 88236, by Communications & Power Industries.

Both manufacturers are recognized for their work in high-reliability electronic components. The presence of two part numbers helps in cross-referencing, sourcing alternatives, or verifying compatibility when replacing parts.

Other Identifiers & Codes

There are additional codes associated with NSN 5960-00-185-9974 that help in supply chain, logistics, and compliance:

  • FLIS Identification: Provides details for criticality, demilitarization, and other management classifications.

  • Demilitarization Codes: These indicate what level of disassembly or destruction is required when the item is decommissioned or disposed.

  • Management Control Codes, MOE, etc.: These reflect how the item is sourced, stored, and controlled—important for military and regulated procurement.

Why It Matters

  1. Legacy Systems & Compatibility
    Many defense, aerospace, or communication systems were designed when electron tubes were standard. Even today, replacements like 5960-00-185-9974 are needed to keep these systems operational.

  2. Resilience
    Metal-enveloped tubes generally offer better protection against environmental stresses—temperature, vibration, EMI—compared to more delicate packages.

  3. Performance in Special Applications
    The cross-field amplifier nature implies that this tube is used where regular amplifiers don’t suffice—perhaps in radar, high-frequency broadcast, or certain high-power RF loads.

  4. Supply Chain Transparency
    With recognized manufacturers (ITT and Communications & Power Industries) and publicly documented NSN details, procurement is easier. ChipsOnSale’s listing confirms performance, manufacturer, and fit.

Usage & Handling Considerations

  • Storage: Keep in dry, climate-controlled conditions to avoid corrosion or damage to metal enclosures.

  • Installation: Ensure correct orientation, cooling, and matching with circuitry designed for cross-field amplification.

  • Replacement: Always verify compatibility using both the part number (145007-1 or SFD267) and the NSN 5960-00-185-9974.

  • Disposal: Follow demilitarization and disposal guidelines per regulatory requirements (which are part of the NSN’s management codes).

Procurement Tips

If you are looking to acquire NSN 5960-00-185-9974:

  • Verify Authenticity: With names like ITT and Communications & Power Industries, check for genuine labels, serials, and manufacturing marks.

  • Request Detailed Specs: Confirm characteristics like power ratings, envelope material, amplification parameters, etc.

  • Compare Suppliers: Use quotes from multiple sources. Parts like this often are pricey due to specialty manufacturing.

  • Lead Time: Specialty tubes may have longer lead times; plan accordingly.

Final Thoughts

NSN 5960-00-185-9974 is more than just a number—it’s a link to electronic tubes that continue to play a vital role in fields where reliability, specific electrical characteristics, and legacy compatibility matter. Because it’s manufactured by proven companies and the specifications are clearly defined (metal envelope, cross-field amplifier), it remains relevant in military and industrial settings. ChipsOnSale’s catalog entry provides the documentation needed for sourcing and certifying such components.
