Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 000-36875 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/In-Line)
• Fastening type (Bayonet Lock)
• Voltage rating (500 V minimum)
• Mating cycles (500 minimum)

Secondary Compatibility Factors:

• Cable group compatibility (must support at least one common cable type)
• Contact termination method (Crimp or Solder capability)
• Shield termination (Crimp)
• Frequency rating (must meet or exceed application requirements)
• Operating temperature range (must encompass -65°C to 165°C or be suitable for intended use)

Substitution Categories:

Direct Equivalents (Active Status): Parts meeting all primary criteria with active product status and full compliance certifications.

Functional Equivalents (Active Status): Parts meeting all primary criteria with enhanced frequency ratings or expanded cable compatibility, suitable for direct replacement in new assemblies.

Legacy Equivalents (Obsolete Status): Parts meeting all primary criteria but with obsolete status; suitable only for legacy system maintenance where original specifications are required.

Cross-Manufacturer Equivalents: Parts from alternative manufacturers meeting all primary criteria with active status and appropriate certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation for New Designs:

Amphenol RF 031-326 is the direct successor to the 000-36875. It maintains identical mechanical and electrical specifications while offering enhanced frequency capability (4 GHz versus 1 GHz) and identical operating temperature range (-65°C to 165°C). The part is Active status with ROHS3 compliance, making it suitable for new designs and legacy replacements where the original cable groups (RG-55, 142, 223, 400) are specified.

Alternative for RG-142 Cable Applications:

TE Connectivity 5225395-6 is suitable for applications specifically using RG-142, 142A, or 142B cables. This part is Active status with RoHS compliance and provides 4 GHz frequency capability. Operating temperature range is -55°C to 85°C, which is narrower than the original part; verify compatibility with intended application environment.

Alternative for RG-55/223 Cable Applications:

TE Connectivity 5227079-6 is suitable for applications using RG-55, 55A, 55B, or 223 cables. This part is Active status with the highest inventory availability (64,520 units) and RoHS compliance. Frequency capability is 4 GHz. Operating temperature range is -55°C to 85°C; verify compatibility with intended application environment.

Cross-Manufacturer Alternative:

Pomona Electronics 4488 offers the broadest cable group compatibility (RG-55, 55A, 55B, 58, 58C, 141, 141A, 142B, 223) and supports both Crimp and Solder termination. Shield termination is Clamp rather than Crimp. This part is Active status with ROHS3 compliance and 4 GHz frequency capability. Operating temperature is not specified; contact manufacturer for thermal specifications if required.

Legacy System Maintenance:

TE Connectivity 5225395-3 (Obsolete status) maintains identical specifications to 5225395-6 and is suitable only for legacy system repairs where original part specifications must be preserved. This part should not be used for new designs or new installations.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 031-326 be used as a direct replacement for the 000-36875?

A: Yes. The 031-326 is the direct successor with identical mechanical and electrical specifications. It maintains the same operating temperature range (-65°C to 165°C), voltage rating (500 V), and cable group compatibility (RG-55, 142, 223, 400). The 031-326 offers enhanced frequency capability (4 GHz versus 1 GHz) and is Active status, making it the recommended choice for both new designs and legacy replacements.

Q: What is the difference between the TE Connectivity 5225395-6 and 5227079-6?

A: Both parts are Active status with 4 GHz frequency capability and 500 V voltage rating. The primary difference is cable group compatibility: 5225395-6 supports RG-142, 142A, and 142B cables, while 5227079-6 supports RG-55, 55A, 55B, and 223 cables. Select based on the specific cable type in your application. The 5227079-6 has significantly higher inventory availability (64,520 units).

Q: Why does the Pomona Electronics 4488 have a different shield termination (Clamp versus Crimp)?

A: The 4488 uses a Clamp shield termination method instead of Crimp. This is a functional difference in how the shield is secured to the connector body. Both methods provide electrical continuity and mechanical retention. Verify that the Clamp termination method is compatible with your cable assembly process and application requirements before substitution.

Q: Can I use the TE Connectivity 5225395-3 (Obsolete) for new installations?

A: No. The 5225395-3 is classified as Obsolete and should be used only for legacy system maintenance and repairs where original part specifications must be preserved. For new installations and new designs, use Active status parts such as the Amphenol RF 031-326, TE Connectivity 5225395-6, or TE Connectivity 5227079-6.

Q: What is the operating temperature range for the Pomona Electronics 4488?

A: The operating temperature range for the 4488 is not specified in the available technical data. Contact Pomona Electronics directly for thermal specifications if your application requires operation outside standard industrial temperature ranges or if you need to verify compatibility with the original part's -65°C to 165°C range.

Q: Are all substitute parts RoHS compliant?

A: The Amphenol RF 031-326 and Pomona Electronics 4488 are ROHS3 compliant. The TE Connectivity parts (5225395-6 and 5227079-6) are RoHS compliant. The TE Connectivity 225395-3 has "Not applicable" RoHS status. Verify RoHS compliance requirements for your specific application and regulatory jurisdiction before final part selection.

Q: Which substitute part has the best inventory availability?

A: TE Connectivity 5227079-6 has the highest inventory availability with 64,520 units in stock. This part is suitable for applications using RG-55, 55A, 55B, or 223 cables and is Active status with RoHS compliance and 4 GHz frequency capability.

Q: Can the 000-36875 be used with RG-400 cable?

A: Yes. The 000-36875 supports RG-400 cable according to its cable group compatibility specification. However, if substituting with alternative parts, verify that the selected substitute also lists RG-400 in its cable group compatibility. The Amphenol RF 031-326 maintains this compatibility, while TE Connectivity alternatives support different cable groups (RG-55/223 or RG-142 variants).
