Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1051942-1 is determined by strict adherence to the following core parameters: SMA connector style, female socket jack type, 50 Ohm impedance, panel mount bulkhead configuration with threaded fastening, and operational frequency capability of 12.4 GHz or greater. All substitute parts must maintain compatibility with the operating temperature range of -65°C to 165°C and utilize beryllium copper center contacts with PTFE dielectric material housed in stainless steel bodies.

The substitute parts are grouped into two categories:

Direct Substitutes maintain all critical electrical and mechanical parameters with active product status:

• Amphenol RF 901-9610-3
• Amphenol SV Microwave M39012/59-3026

Similar Substitutes provide functional equivalence with enhanced frequency capability:

• Molex 0732511960

Termination method variations (solder versus crimp) and shield termination differences are acceptable substitution parameters provided the core connector geometry, impedance, and frequency specifications remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

Amphenol RF 901-9610-3 is the primary direct substitute for the TE Connectivity 1051942-1. This part maintains identical electrical specifications including 50 Ohm impedance, 12.4 GHz maximum frequency, and -65°C to 165°C operating temperature range. The connector features solder termination for both contact and shield, matching the original design. The part holds active product status with ROHS3 compliance and weatherproof ingress protection. Higher voltage rating (375 V versus 250 V) provides enhanced electrical margin. Availability of 26,182 pieces ensures supply continuity.

Amphenol SV Microwave M39012/59-3026 provides direct electrical equivalence with crimp termination for both contact and shield. This part is suitable for applications where crimp termination is preferred or required. Active product status and ROHS3 compliance are confirmed. The connector maintains all core RF parameters and temperature specifications. Lower inventory (703 pieces) should be considered for long-term supply planning.

Molex 0732511960 functions as a similar substitute with enhanced frequency capability (18 GHz versus 12.4 GHz). This part utilizes crimp termination and offers the highest voltage rating (500 V) among all options. The extended frequency range provides additional design margin for future applications. Active product status, ROHS3 compliance, and REACH unaffected status are confirmed. Inventory of 1,184 pieces supports availability requirements.

All three substitute parts are RoHS compliant and maintain the critical SMA jack female socket configuration with 50 Ohm impedance and panel mount bulkhead mounting. Selection should be based on termination method requirements (solder versus crimp), voltage rating needs, and frequency margin specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 901-9610-3 directly replace the TE Connectivity 1051942-1 in existing designs?

A: Yes. The Amphenol RF 901-9610-3 maintains identical SMA connector geometry, 50 Ohm impedance, 12.4 GHz frequency capability, and -65°C to 165°C operating temperature range. Both parts feature solder termination and panel mount bulkhead configuration. The higher voltage rating (375 V versus 250 V) provides additional electrical margin without affecting compatibility.

Q: What is the difference between solder and crimp termination options?

A: The TE Connectivity 1051942-1 features solder termination for both center contact and shield. The Amphenol SV Microwave M39012/59-3026 and Molex 0732511960 utilize crimp termination. Solder termination requires soldering the cable to the connector, while crimp termination uses a mechanical crimping process. Selection depends on assembly process capabilities and design requirements.

Q: Does the Molex 0732511960 provide any advantages over direct substitutes?

A: The Molex 0732511960 offers 18 GHz maximum frequency capability compared to 12.4 GHz for the original part and direct substitutes. This provides additional frequency margin for applications operating below 12.4 GHz. The part also features the highest voltage rating (500 V) among all options. Crimp termination is utilized rather than solder.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TE Connectivity 1051942-1 is RoHS Compliant. All three substitute parts are ROHS3 Compliant, which represents the current RoHS standard. ROHS3 compliance ensures restriction of hazardous substances in accordance with current regulatory requirements.

Q: What cable groups are compatible with each substitute part?

A: The TE Connectivity 1051942-1 supports RG-174, 179, 187, 188, and 316 cable groups. The Amphenol RF 901-9610-3 supports RG-174, 188, 188A, 316, LMR-100, and M17/119-RG174. The Amphenol SV Microwave M39012/59-3026 supports RG-174 and 316. The Molex 0732511960 supports RG-174, 188, and 316. Cable compatibility should be verified for specific applications.

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

A: All parts, including the original and substitutes, are rated for 500 mating cycles. This specification defines the number of times the connector can be mated and unmated while maintaining electrical and mechanical performance within specification. This rating is consistent across all options and indicates equivalent mechanical durability.

Q: How does ingress protection differ among the options?

A: The TE Connectivity 1051942-1 does not specify ingress protection. The Amphenol RF 901-9610-3 features weatherproof ingress protection, providing enhanced environmental sealing. The Amphenol SV Microwave M39012/59-3026 and Molex 0732511960 do not specify ingress protection. Weatherproof protection is beneficial for outdoor or harsh environment applications.

Q: Are there REACH compliance considerations for these parts?

A: The TE Connectivity 1051942-1 does not specify REACH status. The Amphenol RF 901-9610-3 is REACH Affected. The Amphenol SV Microwave M39012/59-3026 is REACH Affected. The Molex 0732511960 is REACH Unaffected. REACH compliance status should be verified against specific regulatory requirements for the target application and end market.
