Engineering Selection Recommendations

Primary Recommendation for RG-213 Cable Applications:

The 51692-2 (TE Connectivity Aerospace, Defense and Marine) is the direct functional equivalent for RG-213 applications. This part maintains identical electrical specifications, cable compatibility, and voltage rating while offering active product status and ROHS3 compliance. The silver body finish and gold center contact plating provide equivalent performance to the original 5225661-2.

Alternative for RG-213 with Enhanced Compliance:

The 11_N-50-7-43/133_NE (Huber+Suhner, Inc.) provides RG-213 compatibility with ROHS3 compliance and active product status. This option features white bronze body finish and maintains all critical electrical parameters.

Multi-Cable Compatibility Option:

The 172102 (Amphenol RF) accommodates multiple cable groups including RG-213, offering the highest voltage rating (1500 V) and ROHS3 compliance. This part is suitable for applications requiring broader cable compatibility or higher voltage margins.

RG-214 Cable Applications:

For RG-214 cable requirements, the 51692-1 or 11_N-50-7-44/133_NE provide active, ROHS3-compliant alternatives with full electrical equivalence.

Compliance Considerations:

All recommended substitutes are ROHS3 compliant or meet equivalent regulatory standards. The original 5225661-2 is RoHS compliant but obsolete. Selection should prioritize active product status and current compliance certifications for new designs and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the 51692-2 directly replace the 5225661-2 in existing assemblies?

A: Yes. The 51692-2 maintains identical electrical specifications, cable compatibility (RG-213), impedance (50 ohms), voltage rating (1000 V), and operating temperature range (-65°C to 165°C). Both are N Type male pin crimp connectors with threaded fastening and free-hanging mounting. Physical dimensions and mating interfaces are equivalent.

Q: What is the difference between the Huber+Suhner variants (11_N-50-7-43/133_NE, 11_N-50-7-43/133_NH, 11_N-50-7-44/133_NE, 11_N-50-7-44/133_NH)?

A: The variants differ by cable group and finish designation. The "7-43" variants are for RG-213 cable; the "7-44" variants are for RG-214 cable. The suffix "NE" and "NH" indicate different finish or packaging specifications. All maintain identical electrical performance and 50 ohm impedance.

Q: Why does the 172102 (Amphenol RF) have a higher voltage rating (1500 V) than the original part (1000 V)?

A: The 172102 is rated for higher voltage operation, providing additional safety margin. This does not affect compatibility with 1000 V applications; the part simply supports a broader operating range. The higher rating reflects design robustness and is suitable for applications requiring enhanced voltage headroom.

Q: Is the 225661-2 a suitable substitute despite being RoHS non-compliant?

A: The 225661-2 is electrically and mechanically equivalent to the 5225661-2 for RG-213 applications. However, it is classified as RoHS non-compliant, whereas the original part is RoHS compliant. For new designs or applications with RoHS requirements, ROHS3-compliant alternatives (51692-2, 11_N-50-7-43/133_NE) are preferred.

Q: Can I use the 1-51692-6 for RG-213 applications?

A: No. The 1-51692-6 is specified for RG-217 cable, which has different physical dimensions than RG-213. While the connector maintains 50 ohm impedance and N Type configuration, cable compatibility is not interchangeable. Use cable-specific variants to ensure proper mechanical fit and electrical performance.

Q: What is the significance of the body finish differences (Nickel, Silver, White Bronze)?

A: Body finish affects corrosion resistance and environmental performance. Nickel and silver finishes provide excellent RF performance and corrosion resistance. White bronze offers similar performance with different aesthetic and environmental characteristics. All finishes are compatible with the specified operating temperature range and mating cycles. Selection depends on environmental exposure and system requirements.

Q: Are all substitute parts rated for 500 mating cycles?

A: Yes. All listed substitutes are rated for a minimum of 500 mating cycles, matching the original 5225661-2 specification. This ensures equivalent mechanical durability and connector lifespan.

Q: Which substitute offers the best long-term availability?

A: The 51692-2 (TE Connectivity Aerospace, Defense and Marine) is recommended for long-term availability. It is active product status, ROHS3 compliant, and manufactured by a major connector supplier with established aerospace and defense supply chains. Current inventory is 724 units.
