Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1050770-1 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded
• Frequency - Max: 18 GHz
• Number of Ports: 1

Secondary Compatibility Factors:

• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Center Contact Plating: Gold
• Mating Cycles: 500 or greater
• Voltage Rating: 335 V or greater
• Operating Temperature Range: Must encompass or exceed -65°C ~ 105°C

Cable Group Compatibility: Substitutes must support RG-405 cable specifications (.085" semi-rigid or flexible variants). Minor variations in cable diameter tolerance (.085" to .086") are acceptable within industry standards.

All identified substitutes meet these criteria and are therefore electrically and mechanically compatible with the original part for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer): TE Connectivity 1050735-1 is a direct equivalent to the 1050770-1. Both parts are manufactured by TE Connectivity AMP Connectors and share identical electrical and mechanical specifications. The 1050735-1 maintains the same impedance, frequency rating, operating temperature range, and mating cycle count. Both parts are classified as obsolete; however, 1050735-1 maintains current inventory availability (1052 pcs) compared to 1050770-1 (1196 pcs).

Active Product Alternatives: For new designs or long-term supply chain requirements, three active product alternatives are available:

SF2906-6002 (Amphenol SV Microwave): This part is actively manufactured and meets all critical electrical parameters. It supports RG-405 flexible cable (.085") and maintains the 18 GHz frequency rating and 50 Ohm impedance. The part is ROHS3 compliant and carries higher inventory availability (3228 pcs). Operating temperature and voltage specifications are not provided in available documentation.

132248 (Amphenol RF): This active product meets all primary substitution criteria with extended operating temperature range (-65°C ~ 165°C), exceeding the original part specification. It supports RG-405 semi-rigid cable (.085" to .086" tolerance) and is ROHS3 compliant. Mating cycle rating matches the original specification at 500 cycles.

HRM-101S(09) (Hirose Electric Co Ltd): This active product is rated for 1000 mating cycles, providing enhanced durability compared to the original 500-cycle specification. Operating temperature range (-55°C ~ 125°C) encompasses the original specification. The part is supplied with additional components (coupling nut, gasket, spring washer) and supports RG-402 cable (.141" semi-rigid). RoHS compliance is confirmed.

Compliance Considerations: All substitute parts maintain RoHS compliance. The original part and 1050735-1 are RoHS Compliant; SF2906-6002 and 132248 are ROHS3 Compliant. REACH status is affected for 1050770-1, 1050735-1, and 132248; REACH status is unaffected for SF2906-6002. All parts carry EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the 1050735-1 be used as a direct replacement for the 1050770-1?

A: Yes. The 1050735-1 is a direct equivalent manufactured by the same company (TE Connectivity AMP Connectors) with identical electrical and mechanical specifications. Both parts are SMA Plug connectors rated for 50 Ohms, 18 GHz maximum frequency, solder termination, and free-hanging mounting. Operating temperature ranges, voltage ratings, and mating cycles are identical.

Q: What is the primary difference between the obsolete parts (1050770-1, 1050735-1) and the active alternatives?

A: The obsolete parts are no longer in active production. The active alternatives (SF2906-6002, 132248, HRM-101S(09)) are currently manufactured and offer improved long-term supply chain availability. All active alternatives maintain the critical electrical parameters: SMA connector style, 50 Ohm impedance, 18 GHz frequency rating, and solder termination.

Q: Are there cable compatibility differences between the substitute parts?

A: The original 1050770-1 and most substitutes support RG-405 cable (.085" semi-rigid). SF2906-6002 supports RG-405 flexible cable (.085"). HRM-101S(09) supports RG-402 cable (.141" semi-rigid), which has a larger diameter. Cable selection must match the connector's mechanical design and the application's requirements.

Q: Which substitute part offers the best durability for high-cycle applications?

A: HRM-101S(09) is rated for 1000 mating cycles, compared to 500 cycles for the original part and other substitutes. This doubled cycle rating provides enhanced durability for applications requiring frequent mating and unmating operations.

Q: What is the operating temperature range for each substitute?

A: The original 1050770-1 operates from -65°C to 105°C. The 1050735-1 matches this range. The 132248 extends to -65°C to 165°C, providing wider temperature capability. The HRM-101S(09) operates from -55°C to 125°C. SF2906-6002 operating temperature is not specified in available documentation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original 1050770-1 and 1050735-1 are RoHS Compliant. SF2906-6002 and 132248 are ROHS3 Compliant, which represents a more recent compliance standard. HRM-101S(09) is RoHS Compliant. All parts meet regulatory requirements for lead-free manufacturing.

Q: What additional components are included with HRM-101S(09)?

A: HRM-101S(09) is supplied with four components: the connector, coupling nut, gasket, and spring washer. The original 1050770-1 includes two components: the connector and contact. This additional hardware may require design consideration for mechanical assembly and integration.

Q: Can I use these connectors interchangeably in existing equipment?

A: Electrical and mechanical compatibility is confirmed across all listed substitutes for the specified parameters. However, physical form factor differences (such as body material, finish, and included hardware) may affect mechanical fit in existing equipment. Verification of mechanical clearance and mounting compatibility is necessary before implementation.

Q: Which substitute offers the best inventory availability?

A: SF2906-6002 (Amphenol SV Microwave) offers the highest current inventory at 3228 pcs. This active product status and inventory level provide the most reliable long-term supply chain option for new procurements.
