Engineering Selection Recommendations

Cinch Connectivity Solutions 142-0203-011

The Cinch 142-0203-011 is an active product with ROHS3 compliance and REACH affected status, matching the regulatory framework of the original TE Connectivity part. This substitute maintains identical operating temperature range, voltage rating, and mating cycle specifications. The connector supports an extended cable group compatibility (RG-161, 174, 179, 187, 188, 316) compared to the original RG-188 specification, providing broader application flexibility. Maximum frequency rating of 12.4 GHz is lower than the original 18 GHz specification; this substitute is suitable for applications operating within the 12.4 GHz frequency envelope. The clamp shield termination method matches the original design approach.

Winchester Interconnect 910A204M

The Winchester 910A204M is an active product with RoHS compliance and Series 900 designation. This substitute provides a higher voltage rating of 500 V compared to the original 250 V specification, offering enhanced electrical performance margin. Maximum frequency rating of 12.5 GHz is lower than the original 18 GHz specification; this substitute is suitable for applications operating within the 12.5 GHz frequency envelope. The crimp shield termination differs from the original clamp method, requiring evaluation of assembly process compatibility. Cable group support includes RG-174, 188, and 316, with RG-188 compatibility maintained.

Both substitute parts maintain core SMA connector functionality, 50 ohm impedance, solder contact termination, free hanging mounting, and threaded fastening. Selection between substitutes depends on specific application frequency requirements, voltage margin requirements, and assembly process compatibility with shield termination methods.

Frequently Asked Questions (FAQ)

Q: Can the Cinch 142-0203-011 be used in applications requiring 18 GHz operation?

A: No. The Cinch 142-0203-011 has a maximum frequency rating of 12.4 GHz. Applications requiring 18 GHz operation exceed this specification. The original TE Connectivity AMP 1050720-1 operates to 18 GHz; no active substitute identified maintains this frequency specification.

Q: What is the difference between clamp and crimp shield termination?

A: The TE Connectivity AMP 1050720-1 and Cinch 142-0203-011 use clamp shield termination, which secures the cable shield through mechanical clamping. The Winchester 910A204M uses crimp shield termination, which secures the cable shield through permanent deformation of a ferrule. Assembly processes and tooling differ between these methods.

Q: Are both substitute parts RoHS compliant?

A: Yes. The Cinch 142-0203-011 is ROHS3 compliant. The Winchester 910A204M is RoHS compliant. Both meet RoHS regulatory requirements.

Q: What cable types are compatible with each substitute?

A: The Cinch 142-0203-011 supports RG-161, 174, 179, 187, 188, and 316 cable groups. The Winchester 910A204M supports RG-174, 188, and 316 cable groups. Both support RG-188, which is the primary cable group for the original TE Connectivity part.

Q: Do the substitute parts have the same operating temperature range?

A: Yes. Both the Cinch 142-0203-011 and Winchester 910A204M operate across -65°C to 165°C, matching the original TE Connectivity AMP 1050720-1 specification.

Q: What is the voltage rating difference between the substitutes?

A: The Cinch 142-0203-011 maintains the original 250 V voltage rating. The Winchester 910A204M provides a higher 500 V voltage rating, offering additional electrical performance margin for high-voltage applications.

Q: Are the substitute parts available in bulk packaging?

A: Yes. Both the Cinch 142-0203-011 and Winchester 910A204M are available in bulk packaging with current inventory levels of 2701 and 1179 units respectively.

Q: What is the mating cycle rating for the substitute parts?

A: Both substitute parts are rated for 500 mating cycles, matching the original TE Connectivity AMP 1050720-1 specification.

Q: Do the substitute parts include the same components as the original?

A: No. The TE Connectivity AMP 1050720-1 includes 5 components (connector, clamp, collar, contact, insulator). The Cinch 142-0203-011 includes 6 components (connector, clamp cone, clamp nut, clamp stem, contact, insulator). The Winchester 910A204M includes 3 components (connector, contact, ferrule). Component count and configuration differ between parts.
