Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (916B524FT): The 916B524FT remains the primary specification when Winchester Interconnect supply is available. This part carries RoHS compliance certification and maintains active production status with confirmed inventory of 1099 units.

Substitute Part Selection (132145): The Amphenol RF 132145 qualifies as a direct substitute when Winchester Interconnect 916B524FT is unavailable. This part meets all critical electrical and mechanical parameters with the following considerations:

• Frequency capability of 12.4 GHz is within acceptable range for applications specified at 12.5 GHz maximum
• ROHS3 compliance exceeds RoHS baseline requirements
• Extended insulation feature provides additional design margin
• Inventory availability of 1612 units supports procurement continuity
• Packaging format (Bag) differs from primary part but does not affect functional compatibility

Both parts are rated for identical operating temperature ranges, mating cycle counts, and moisture sensitivity levels, confirming environmental equivalence.

Frequently Asked Questions (FAQ)

Q: Can 132145 be used as a direct replacement for 916B524FT in all applications?

A: Yes, the 132145 meets all critical electrical and mechanical parameters for direct substitution. The 12.4 GHz maximum frequency of the 132145 is compatible with applications specified for the 916B524FT's 12.5 GHz capability. Both parts share identical impedance, termination methods, mounting configuration, and environmental ratings.

Q: What is the difference between "Solder Tab" and "Solder" contact termination?

A: Both termination methods use solder for electrical connection. The terminology difference reflects manufacturer documentation conventions but does not indicate functional incompatibility. Both parts are designed for solder-based assembly processes.

Q: Does the packaging difference (unspecified for 916B524FT versus Bag for 132145) affect compatibility?

A: No. Packaging format affects only handling, storage, and logistics. It does not impact electrical performance, mechanical fit, or functional compatibility in the application.

Q: Are both parts suitable for high-frequency RF applications?

A: Yes. Both the 916B524FT and 132145 are rated for operation up to 12.4-12.5 GHz with 50-ohm impedance, PTFE dielectric, and gold-plated brass construction. These specifications support RF applications across microwave frequency bands.

Q: What is the significance of the Extended Insulation feature on the 132145?

A: Extended insulation on the 132145 provides additional dielectric material coverage, offering enhanced electrical isolation. This feature is compatible with applications requiring the 916B524FT and represents an equivalent or superior design characteristic.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The 916B524FT carries RoHS compliance certification. The 132145 carries ROHS3 compliance, which represents a more recent regulatory standard. Both parts meet MSL 1 (Unlimited) moisture sensitivity requirements and are suitable for standard industrial and commercial applications.

Q: What is the mating cycle rating, and does it affect part selection?

A: Both parts are rated for 500 mating cycles, indicating the number of times the connector can be mated and unmated while maintaining electrical and mechanical specifications. This identical rating confirms equivalent reliability and service life expectations.
