Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 916B524B is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Impedance (50 Ohms), connector style (SMA), connector type (Plug, Male Pin), and maximum frequency rating must match or exceed the main part specification.

Mechanical Parameters: Contact termination method (Solder Cup), shield termination (Solder), mounting type (Panel Mount), mounting feature (Flange), and fastening type (Threaded) must be identical.

Material & Environmental Parameters: Body material (Brass), body finish (Gold), center contact material (Brass), center contact plating (Gold), and dielectric material (PTFE) must be consistent. Operating temperature range and mating cycle ratings must meet or exceed the main part.

Compliance Parameters: RoHS compliance status and moisture sensitivity level must be equivalent or superior.

The Amphenol RF 132145 meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Part - Winchester Interconnect 916B524B: Active product status with RoHS compliance. Current inventory of 812 pieces supports immediate procurement requirements. Suitable for applications requiring standard SMA male plug configuration with 50-ohm impedance up to 12.5 GHz.

Substitute Part - Amphenol RF 132145: Active product status with ROHS3 compliance and REACH affected designation. Higher inventory availability (1612 pieces) supports extended procurement windows. Maximum frequency rating of 12.4 GHz remains within acceptable parameters for most RF applications. Extended insulation feature provides additional design flexibility. Packaging in bag format differs from main part but does not affect electrical or mechanical performance.

Both parts satisfy identical electrical and mechanical requirements for SMA connector plug applications. Selection between primary and substitute parts should be based on inventory availability, delivery timeline, and packaging requirements specific to manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 132145 directly replace the Winchester 916B524B in existing designs?

A: Yes. Both connectors maintain identical SMA male plug configuration, 50-ohm impedance, panel mount flange design, and threaded fastening. Electrical and mechanical compatibility is confirmed across all critical parameters.

Q: What is the significance of the 0.1 GHz frequency difference between the two parts?

A: The Winchester 916B524B operates to 12.5 GHz while the Amphenol RF 132145 operates to 12.4 GHz. This 0.1 GHz difference does not affect compatibility for standard RF applications operating below 12.4 GHz. Applications requiring operation above 12.4 GHz must use the Winchester part.

Q: How do the packaging differences affect component selection?

A: The Winchester 916B524B packaging is not specified in available data. The Amphenol RF 132145 is supplied in bag packaging. Packaging format does not affect electrical performance or mechanical compatibility. Selection should consider manufacturing assembly requirements and inventory management procedures.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both connectors operate across the identical temperature range of -65°C to 165°C, supporting applications in thermal environments within this specification.

Q: What compliance certifications apply to each part?

A: Winchester 916B524B carries RoHS compliance certification. Amphenol RF 132145 carries ROHS3 compliance certification and is REACH affected. Both meet current regulatory requirements for electronic component procurement.

Q: Do the solder termination specifications differ between the two parts?

A: The Winchester 916B524B specifies solder cup contact termination with solder shield termination. The Amphenol RF 132145 specifies solder contact termination with solder shield termination. Both employ solder-based termination methods compatible with standard PCB assembly processes.
