Substitute Part Grouping Explanation

Substitution of the 225974-1 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Connector style (BNC)
Connector type (Plug, Male Pin)
Impedance (50 Ohms)
Mounting type (Free Hanging, Right Angle)
Fastening type (Bayonet Lock)
Number of ports (1)
Frequency maximum (4 GHz or higher)
Voltage rating (500 V or higher)
Mating cycles (500 or higher)

Secondary Compatibility Factors:

Cable group compatibility (RG-58 series minimum)
Contact and shield termination methods
Dielectric material (PTFE)

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity AMP Connectors 225973-1

The 225973-1 serves as the direct parametric equivalent to the obsolete 225974-1. Both components share identical electrical specifications, mechanical configuration, and performance characteristics across all critical parameters including impedance, frequency response, voltage rating, and mating cycles. The 225973-1 maintains active product status, ensuring ongoing availability and supply chain continuity. The only material difference is the body finish (silver versus nickel), which does not affect electrical performance or mechanical compatibility. This part is the preferred replacement for direct substitution in existing designs.

Secondary Recommendation: Amphenol RF 031-335

The 031-335 provides full parametric equivalence with extended cable group compatibility, supporting RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cables. This connector features an enhanced operating temperature range of -65°C to 165°C compared to the original -55°C to 85°C specification. The 031-335 holds ROHS3 compliance and REACH affected status, meeting modern regulatory requirements. This part is suitable for applications requiring broader cable compatibility or extended thermal performance.

Tertiary Option: Molex 0731000015

The 0731000015 provides functional equivalence with a critical difference in contact termination methodology. This connector employs solder termination for the center contact rather than crimp termination. The part supports RG-58C, 141A, and 303 cable groups and holds ROHS3 compliance. Selection of this part requires verification that solder termination is compatible with the assembly process and application requirements. Frequency and insertion loss specifications are not provided for this component.

Frequently Asked Questions (FAQ)

Q: Can the 225973-1 be used as a direct replacement for the 225974-1?

A: Yes. The 225973-1 is a parametric equivalent with identical electrical and mechanical specifications. The only difference is the body finish material (silver versus nickel), which does not affect electrical performance, mechanical fit, or cable compatibility. The 225973-1 is the recommended replacement for the obsolete 225974-1.

Q: What is the primary difference between the 031-335 and the 225974-1?

A: The 031-335 maintains all critical electrical and mechanical parameters but offers extended cable group compatibility (supporting RG-141, 303, LMR-195, and additional cable types) and an enhanced operating temperature range (-65°C to 165°C versus -55°C to 85°C). The 031-335 also provides ROHS3 compliance, whereas the 225974-1 is non-compliant.

Q: Why is the Molex 0731000015 listed as a substitute if it uses solder termination instead of crimp?

A: The 0731000015 is listed as a similar alternative based on matching connector style, type, impedance, mounting configuration, and fastening method. However, the contact termination difference (solder versus crimp) represents a significant process change. This part is suitable only for applications where solder termination is acceptable and compatible with assembly procedures.

Q: Are all substitute parts compatible with RG-58 cable?

A: Yes. All listed substitutes support RG-58 cable compatibility. The 031-335 and 0731000015 extend compatibility to additional cable types (RG-141, 303, LMR-195, and others), but all maintain minimum RG-58 series support.

Q: What is the significance of the ROHS3 compliance difference?

A: The 225974-1 and 225973-1 are RoHS non-compliant, whereas the 031-335 and 0731000015 are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating compliance, the 031-335 or 0731000015 must be selected. For legacy systems without regulatory constraints, non-compliant parts remain functionally equivalent.

Q: Can the 225973-1 be used in applications requiring extended temperature operation?

A: The 225973-1 maintains the same operating temperature range as the 225974-1 (-55°C to 85°C). For applications requiring extended thermal performance, the 031-335 with its -65°C to 165°C range is the appropriate selection.

Q: What packaging differences exist among the substitute parts?

A: The 225974-1 and 225973-1 packaging is not specified. The 031-335 is supplied in bulk packaging, while the 0731000015 is supplied in bag packaging. Packaging format may affect procurement quantities and handling procedures but does not impact electrical or mechanical performance.

Q: Are all substitutes rated for 500 mating cycles?

A: Yes. All listed substitutes maintain the 500 mating cycle rating, ensuring equivalent mechanical durability and connector lifespan.
