Engineering Selection Recommendations

Primary Substitute: Cinch Connectivity Solutions 142-1701-626

The 142-1701-626 is the preferred substitute for the obsolete TE Connectivity AMP 1052634-1. Both components are ROHS3 compliant and REACH affected, ensuring regulatory alignment. The 142-1701-626 maintains identical core electrical and mechanical parameters including 50 Ohm impedance, compression contact termination, screw shield termination, panel mount configuration with flange, and PTFE dielectric material. Operating temperature range (-65°C ~ 165°C) and mating cycle rating (500) are identical. The substitute features a higher maximum frequency rating (26.5 GHz versus 18 GHz), providing enhanced performance margin. Housing color is silver, matching the original part. Active product status ensures ongoing availability and supply chain support.

Secondary Substitute: Cinch Connectivity Solutions 142-1701-621

The 142-1701-621 is an alternative substitute meeting all core substitution parameters. This component is RoHS compliant and maintains identical electrical and mechanical specifications. The primary distinction is housing color (gold versus silver) and body finish (gold plating). Maximum frequency rating is 26.5 GHz. Active product status supports long-term availability. Selection of this substitute is appropriate when gold housing color is functionally acceptable or preferred for specific applications.

Both substitute parts are manufactured by Cinch Connectivity Solutions and classified as active products, providing superior supply chain continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the Cinch Connectivity Solutions 142-1701-621 and 142-1701-626 be used interchangeably with the TE Connectivity AMP 1052634-1?

A: Both Cinch parts meet all core electrical and mechanical substitution parameters. The primary differences are body material (brass versus stainless steel), body finish (gold or nickel versus unspecified), and housing color (gold or silver). These variations do not affect electrical performance or mechanical compatibility in standard panel mount applications. Selection between the two Cinch substitutes depends on specific application requirements regarding housing color and finish.

Q: What is the significance of the higher frequency maximum rating in the substitute parts?

A: The substitute parts are rated to 26.5 GHz maximum frequency, compared to 18 GHz for the original part. This higher frequency capability provides additional performance margin and supports applications requiring extended frequency range operation. The substitute parts remain fully compatible with applications designed for the original 18 GHz maximum frequency.

Q: Are there compliance differences between the original part and substitutes?

A: The original TE Connectivity AMP 1052634-1 is ROHS3 compliant and REACH affected. The Cinch 142-1701-626 is also ROHS3 compliant and REACH affected, providing identical regulatory status. The Cinch 142-1701-621 is RoHS compliant (not specifically ROHS3 designated). All three parts carry EAR99 ECCN classification and 8536.69.4010 HTSUS code. For applications requiring ROHS3 compliance and REACH status, the 142-1701-626 is the preferred substitute.

Q: What is the difference between "Receptacle, Female Socket" and "Jack, Female Socket" connector types?

A: Both designations refer to female socket connectors in SMA connector terminology. The functional electrical and mechanical characteristics are identical for the specified parameters. The terminology variation reflects different manufacturer naming conventions for the same connector type.

Q: How do the body material differences affect performance?

A: The original part uses stainless steel body material, while substitute parts use brass body material. Both materials provide adequate shielding and mechanical support for 50 Ohm SMA connectors. Brass body material with appropriate plating (gold or nickel) provides equivalent RF performance and environmental protection. Material selection does not affect electrical impedance, frequency response, or operating temperature range.

Q: Are the substitute parts available in sufficient quantity for production requirements?

A: Current inventory status shows 905 units of 142-1701-621 and 939 units of 142-1701-626 in stock. Both substitute parts are classified as active products, ensuring ongoing manufacturing availability and supply chain support, unlike the obsolete original part with limited remaining inventory of 1306 units.

Q: What is the voltage rating specification for the substitute parts?

A: The Cinch substitute parts are rated for 335 V. The original TE Connectivity AMP part does not specify a voltage rating in the provided parameters. The 335 V rating of the substitutes supports standard RF connector applications and does not represent a limiting factor for typical coaxial connector installations.
