SMA Connector Plug 916B524 Equivalent & Substitute Parts

Part Overview

The Winchester Interconnect 916B524 is an SMA connector plug with male pin configuration, designed for 50-ohm RF applications. This straight connector features panel mount capability with threaded fastening and solder cup termination for both center contact and shield. The component operates across a frequency range up to 12.5 GHz with an operating temperature range of -65°C to 165°C.

The 916B524 maintains Active product status and is RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate component alternatives meeting equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 916B524 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Impedance must be 50 Ohms. Frequency maximum rating must support the application bandwidth. Operating temperature range must encompass -65°C to 165°C minimum.

Mechanical Configuration: Connector style must be SMA. Connector type must be Plug with Male Pin. Contact termination must be Solder Cup. Shield termination must be Solder. Mounting type must be Panel Mount with Flange feature. Fastening type must be Threaded.

Material & Environmental Compliance: Center contact and body materials must be Brass. Dielectric material must be PTFE. Mating cycle rating must be 500 cycles minimum. RoHS compliance status must be maintained. MSL rating must be 1 (Unlimited).

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

Parameter Comparison

Engineering Selection Recommendations

Both the Winchester Interconnect 916B524 and Amphenol RF 132145 maintain Active product status with full regulatory compliance. The 916B524 carries RoHS Compliant certification, while the 132145 carries ROHS3 Compliant certification, indicating enhanced compliance scope.

The frequency maximum specification differs marginally: 916B524 at 12.5 GHz versus 132145 at 12.4 GHz. This 0.1 GHz difference does not affect substitution eligibility for applications operating within the lower frequency specification.

Both components share identical electrical impedance (50 Ohms), mechanical configuration (SMA Plug, Male Pin, Panel Mount, Threaded), material composition (Brass body and center contact with PTFE dielectric), and environmental ratings (operating temperature -65°C to 165°C, 500 mating cycles, MSL 1).

Selection between these parts should be based on availability, packaging format (Winchester in standard packaging, Amphenol RF in Bag), and inventory levels (Winchester 697 Pcs, Amphenol RF 1612 Pcs).

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 132145 directly replace the Winchester 916B524 in existing designs?

A: Yes. Both connectors meet identical specifications for SMA Plug configuration, 50-ohm impedance, solder termination, panel mount flange, threaded fastening, operating temperature range, and mating cycle rating. The frequency maximum difference of 0.1 GHz does not affect compatibility for applications designed within the lower specification.

Q: What is the significance of the contact termination difference listed as "Solder Cup" versus "Solder"?

A: Both termination methods are solder-based. The Winchester 916B524 specifies "Solder Cup" as the contact termination method, while the Amphenol RF 132145 specifies "Solder." Both achieve equivalent electrical and mechanical connection through solder attachment.

Q: Are there compliance differences between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant represents an enhanced compliance designation with broader scope than RoHS Compliant. The Amphenol RF 132145 with ROHS3 Compliant status meets all requirements of the Winchester 916B524 with RoHS Compliant status and extends compliance coverage further.

Q: Does packaging format affect electrical or mechanical performance?

A: No. The Winchester 916B524 standard packaging and Amphenol RF 132145 Bag packaging contain identical components. Packaging format affects only handling, storage, and inventory management, not connector performance or specifications.

Q: What is the MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates Moisture Sensitivity Level 1 with unlimited floor life. Both connectors can be stored and handled without time-based moisture absorption constraints, simplifying inventory management and component shelf life.

Q: Are the mating cycle ratings equivalent?

A: Yes. Both the 916B524 and 132145 are rated for 500 mating cycles, indicating identical mechanical durability and connector life expectancy under normal use conditions.
