SMP-J-C-GF-ST-CA7 Equivalent & Substitute Parts

Part Overview

The SMP-J-C-GF-ST-CA7 is a 50 Ohm SMP Connector Jack with female socket configuration, designed for cable termination in RF applications. Manufactured by Samtec Inc., this connector features solder termination for both contact and shield, free hanging (in-line) mounting, and operates across a frequency range up to 40 GHz. The connector is ROHS3 compliant and maintains an active product status. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component procurement, inventory management, or design flexibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SMP-J-C-GF-ST-CA7 and 127-0693-001 maintain active product status and are ROHS3 compliant, ensuring regulatory compliance for current and future applications. The substitute part 127-0693-001 provides documented insertion loss specification of 0.12 dB, whereas the main part does not specify this parameter. Both connectors are MSL Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. Selection between these parts may be based on availability, lead time, or procurement source, as all electrical and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can 127-0693-001 be used as a direct replacement for SMP-J-C-GF-ST-CA7?

A: Yes. Both connectors share identical electrical and mechanical specifications, including 50 Ohm impedance, SMP jack female socket configuration, solder termination, RG-405 cable compatibility, 40 GHz frequency rating, and operating temperature range of -65°C to 165°C.

Q: What are the key parameters that determine substitution eligibility?

A: Connector style (SMP), connector type (jack, female socket), impedance (50 Ohms), contact and shield termination method (solder), mounting type (free hanging in-line), cable group (RG-405), frequency rating (40 GHz), and material specifications (beryllium copper body with gold finish, PTFE dielectric).

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) rating. The substitute part 127-0693-001 includes REACH Affected status, which is not specified for the main part.

Q: Does the insertion loss specification affect substitution?

A: The substitute part 127-0693-001 specifies 0.12 dB insertion loss, while the main part does not provide this specification. This documented value does not preclude substitution; it represents additional technical data available for the Cinch part.

Q: Are packaging and inventory considerations relevant to substitution?

A: Both parts are supplied in bulk packaging. Current inventory shows 934 pcs for SMP-J-C-GF-ST-CA7 and 813 pcs for 127-0693-001. Packaging format is identical, and both include 2 pcs per unit (1 connector, 1 contact).
