Engineering Selection Recommendations

Primary Substitute: 32S107-303L5 (Rosenberger)

The Rosenberger 32S107-303L5 is the preferred substitute for the 1051664-1. This part maintains full parametric equivalence across all critical electrical and mechanical specifications: SMA plug configuration, 50 Ohm impedance, solder contact termination, crimp shield termination, 12.4 GHz maximum frequency, and identical operating temperature range (-65°C ~ 165°C). The 32S107-303L5 is currently in active production status, ensuring long-term supply availability. The connector exceeds the voltage rating requirement (480 V versus 250 V), providing additional design margin. RoHS compliance is confirmed. This part is suitable for direct replacement in applications utilizing RG-316 cable.

Secondary Substitute: 1051654-1 (TE Connectivity AMP Connectors)

The TE Connectivity 1051654-1 provides parametric equivalence with identical contact termination (solder) and shield termination (crimp) characteristics. Operating temperature, voltage rating, and mating cycle specifications match the main part exactly. This connector is also classified as obsolete; however, it remains available in inventory. The 1051654-1 is compatible with RG-188 cable group. This part is suitable when maintaining consistency with the original manufacturer is required.

Alternative Substitute: 2903-6001 (Amphenol SV Microwave)

The Amphenol SV Microwave 2903-6001 differs from the main part in contact termination method (crimp versus solder). This part is currently in active production status, providing superior supply chain continuity. The connector maintains electrical equivalence (50 Ohm impedance, 12.4 GHz frequency, SMA plug configuration) and mechanical compatibility (threaded fastening, free hanging mounting). The 2903-6001 supports a broader cable group range (RG-174, 179B, 187A, 188A, 316), offering greater application flexibility. Operating temperature and voltage rating specifications are not provided for this part. Selection of the 2903-6001 requires confirmation that crimp termination is acceptable for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the 2903-6001 (crimp termination) be used as a direct replacement for the 1051664-1 (solder termination)?

A: The 2903-6001 maintains electrical and mechanical equivalence with the 1051664-1 across all core parameters (impedance, frequency, connector style, mounting type, fastening type). However, the contact termination method differs: the 2903-6001 uses crimp termination while the 1051664-1 uses solder termination. Direct substitution is possible only if the application design and assembly process accommodate crimp termination. Cable preparation and assembly procedures will differ between solder and crimp termination methods.

Q: What is the difference between the 1051664-1 and 1051654-1?

A: Both connectors are manufactured by TE Connectivity AMP Connectors and share identical electrical specifications (50 Ohm impedance, 12.4 GHz frequency, solder contact termination, crimp shield termination). The primary difference is cable group compatibility: the 1051664-1 is rated for RG-174 cable, while the 1051654-1 is rated for RG-188 cable. Both parts are obsolete. Selection between these parts depends on the specific cable type used in the application.

Q: Why is the 32S107-303L5 recommended as the primary substitute?

A: The 32S107-303L5 is recommended because it is currently in active production status, ensuring long-term supply availability and support. It maintains full parametric equivalence with the 1051664-1 across all critical electrical and mechanical parameters. The connector exceeds the voltage rating requirement (480 V versus 250 V), providing additional design margin. RoHS compliance is confirmed. The part is suitable for applications utilizing RG-316 cable.

Q: Are there any compatibility issues with cable group differences?

A: Cable group designation indicates the connector's compatibility with specific cable types and dimensions. The 1051664-1 is rated for RG-174 cable. Substitute parts may support different cable groups: the 1051654-1 supports RG-188, the 32S107-303L5 supports RG-316, and the 2903-6001 supports RG-174, 179B, 187A, 188A, and 316. Selection of a substitute part with a different cable group rating requires confirmation that the cable type used in the application is compatible with the substitute connector.

Q: What does "free hanging (in-line)" mounting type mean?

A: Free hanging (in-line) mounting indicates that the connector is designed to be mounted directly on a cable without a panel or chassis mounting interface. The connector remains suspended by the cable itself. All substitute parts listed maintain this mounting type, ensuring mechanical compatibility with applications designed for in-line cable mounting.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 1051664-1 is RoHS Compliant. The 1051654-1 is RoHS Compliant. The 32S107-303L5 is RoHS Compliant. The 2903-6001 is ROHS3 Compliant. All parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the significance of the 500 mating cycle rating?

A: The mating cycle rating of 500 indicates the connector is rated for 500 connect/disconnect cycles under normal operating conditions. All substitute parts maintain this specification, ensuring equivalent mechanical durability and reliability for applications requiring repeated mating and unmating operations.

Q: Can operating temperature specifications be used to eliminate substitute options?

A: The 1051664-1 operates across -65°C to 165°C. The 1051654-1 and 32S107-303L5 maintain identical operating temperature specifications. The 2903-6001 does not provide an operating temperature specification in available documentation. For applications requiring confirmed operation across the full -65°C to 165°C range, the 32S107-303L5 or 1051654-1 are preferred selections.
