Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1051933-1 is determined by strict alignment of the following critical parameters:

Core Compatibility Requirements:

• Connector Style: SMA (all substitutes must be SMA)
• Connector Type: Jack, Female Socket (all substitutes must be female socket configuration)
• Impedance: 50 Ohms (all substitutes must maintain 50 Ohm impedance)
• Mounting Type: Panel Mount with Bulkhead - Front Side Nut configuration
• Fastening Type: Threaded
• Shield Termination: Crimp

Functional Equivalence Parameters:

• Mating Cycles: 500 (all substitutes meet or exceed this specification)
• Center Contact Material: Beryllium Copper (all substitutes utilize this material)
• Dielectric Material: Polytetrafluoroethylene (PTFE) (all substitutes use PTFE)

Acceptable Variations:

• Contact Termination: The main part specifies solder termination. Substitutes with crimp or crimp/solder hybrid termination are acceptable provided the connector maintains mechanical and electrical compatibility with the panel mount bulkhead configuration.
• Frequency - Max: The main part specifies 6 GHz maximum. Substitutes with higher frequency ratings (12.4 GHz) are acceptable as they represent enhanced capability within the same connector family.
• Operating Temperature: The main part specifies -40°C to 95°C. Substitutes with extended temperature ranges (-65°C to 165°C) are acceptable as they provide broader operational capability.
• Cable Group: Substitutes supporting the primary cable groups (RG-174, 316) with additional cable group support are acceptable.

The identified substitutes meet these criteria while maintaining functional equivalence for RF coaxial connector applications.

Parameter Comparison

Engineering Selection Recommendations

M39012/59-3026 (Amphenol SV Microwave)

This substitute is an active product with ROHS3 compliance and REACH affected status. The connector maintains SMA jack female socket configuration with 50 Ohm impedance and panel mount bulkhead mounting. The primary difference is crimp contact termination versus solder termination on the main part. The M39012/59-3026 supports a subset of cable groups (RG-174, 316) and operates across an extended temperature range (-65°C to 165°C). Frequency capability is enhanced to 12.4 GHz. This substitute is suitable for applications where crimp termination is acceptable and extended temperature operation is beneficial.

142-0303-401 (Cinch Connectivity Solutions)

This substitute is an active product with RoHS compliance and MSL 1 rating. The connector maintains SMA jack female socket configuration with 50 Ohm impedance and panel mount bulkhead mounting. The 142-0303-401 offers flexible contact termination (crimp or solder), providing direct compatibility with solder-based assembly processes. The connector supports an expanded cable group range (RG-161, 174, 188, 316) and operates across an extended temperature range (-65°C to 165°C). Frequency capability is enhanced to 12.4 GHz. Voltage rating matches the main part at 250 V. This substitute provides the closest functional equivalence to the 1051933-1 for panel mount applications.

901-9602-3 (Amphenol RF)

This substitute is an active product with ROHS3 compliance and REACH affected status. The connector maintains SMA jack female socket configuration with 50 Ohm impedance and solder contact termination, matching the main part's termination method. However, the mounting type is free hanging (in-line) rather than panel mount bulkhead. This configuration difference makes the 901-9602-3 unsuitable as a direct substitute for panel mount applications. The connector includes weatherproof ingress protection and operates across an extended temperature range (-65°C to 165°C) with enhanced voltage rating (375 V) and frequency capability (12.4 GHz). This part is applicable only for in-line cable assembly applications, not panel mount installations.

Frequently Asked Questions (FAQ)

Q: Can the M39012/59-3026 replace the 1051933-1 in existing panel mount applications?

A: The M39012/59-3026 maintains the same SMA jack female socket configuration, 50 Ohm impedance, and panel mount bulkhead mounting feature. The primary difference is crimp contact termination versus solder termination. If the application assembly process can accommodate crimp termination, this substitute is mechanically and electrically compatible. Cable group support includes RG-174 and RG-316, which are primary cable groups for the main part.

Q: What is the key difference between the 142-0303-401 and the 1051933-1?

A: Both connectors are SMA jack female socket, 50 Ohm, panel mount bulkhead configurations. The 142-0303-401 offers flexible contact termination (crimp or solder), allowing direct substitution in solder-based assembly processes. The 142-0303-401 supports an expanded cable group range and operates across a wider temperature range (-65°C to 165°C versus -40°C to 95°C). Voltage rating is identical at 250 V. The 142-0303-401 is the most functionally equivalent substitute for panel mount applications.

Q: Why is the 901-9602-3 not recommended as a direct substitute?

A: The 901-9602-3 differs fundamentally in mounting type. It is configured as free hanging (in-line) rather than panel mount bulkhead. This configuration difference makes it mechanically incompatible with panel mount installations. The 901-9602-3 is applicable only for in-line cable assembly applications where the connector is soldered directly to cable conductors without panel mounting.

Q: Are all substitutes RoHS compliant?

A: The 1051933-1 is RoHS Compliant. The M39012/59-3026 and 901-9602-3 are ROHS3 Compliant. The 142-0303-401 is RoHS Compliant. All substitutes meet RoHS requirements. The M39012/59-3026 and 901-9602-3 carry REACH Affected status, indicating additional regulatory considerations for certain applications.

Q: What cable groups are supported by each substitute?

A: The 1051933-1 supports RG-174, 179, 187, 188, 316. The M39012/59-3026 supports RG-174, 316 (subset). The 142-0303-401 supports RG-161, 174, 188, 316 (expanded). The 901-9602-3 supports RG-174, 179, 187, 188, 316 (identical). For applications using RG-179 or RG-187, the 901-9602-3 is the only substitute with identical cable group support, though it is limited to in-line applications.

Q: Do the substitutes maintain the same mating cycle rating?

A: Yes. The 1051933-1 specifies 500 mating cycles. All identified substitutes (M39012/59-3026, 142-0303-401, 901-9602-3) maintain the same 500 mating cycle rating.

Q: What is the significance of the extended operating temperature range in the substitutes?

A: The 1051933-1 operates from -40°C to 95°C. The M39012/59-3026, 142-0303-401, and 901-9602-3 all operate from -65°C to 165°C. The extended range provides broader operational capability for applications requiring operation in extreme temperature environments. For applications within the original -40°C to 95°C range, the extended temperature capability of substitutes does not introduce incompatibility.

Q: Are there inventory considerations for selecting a substitute?

A: Current inventory levels are: 1051933-1 (1100 pcs), M39012/59-3026 (703 pcs), 142-0303-401 (738 pcs), 901-9602-3 (973 pcs). All parts are listed as new original in stock. Inventory availability should be evaluated against production volume requirements and lead time considerations.
