Engineering Selection Recommendations

TE Connectivity AMP Connectors 5221402-2 (Direct Substitute)

The 5221402-2 is the primary direct substitute for the obsolete 221402-2. This part maintains identical electrical and mechanical specifications, including impedance, frequency response, voltage rating, and mating cycles. The 5221402-2 is currently in active production status with 727 pieces in stock inventory. This component achieves RoHS compliance and REACH affected status, addressing regulatory requirements absent in the original part. The direct manufacturer lineage (TE Connectivity AMP Connectors) ensures design continuity and compatibility with existing cable assemblies and termination tooling.

Amphenol RF 031-71010 (Similar Substitute)

The 031-71010 provides an alternative from a different manufacturer while maintaining core BNC 75 ohm specifications. This part offers enhanced performance characteristics, including maximum frequency of 4 GHz (versus 2 GHz) and extended operating temperature range of -65°C ~ 165°C (versus -55°C ~ 85°C). The 031-71010 achieves ROHS3 compliance and REACH affected status. Insertion loss is 0.2 dB, representing a 0.05 dB increase over the original specification. Cable group compatibility extends to RG-59, 59B, 62, 140, 210, and Belden series 8241, 8263, 8279, 9209. This part is suitable for applications requiring broader temperature operation or higher frequency performance margins.

Both substitute parts maintain the critical 75 ohm impedance, bayonet lock fastening, crimp termination, and 500 mating cycle rating required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 5221402-2 directly replace the obsolete 221402-2 in existing assemblies?

A: Yes. The 5221402-2 maintains identical electrical and mechanical parameters including impedance, frequency response, voltage rating, and mating cycles. The connector style, mounting type, and termination method are unchanged. Existing cable assemblies and termination tooling are compatible.

Q: What is the primary difference between the 5221402-2 and 031-71010 substitutes?

A: The 5221402-2 is a direct manufacturer equivalent from TE Connectivity AMP Connectors with identical specifications to the original part. The 031-71010 is from Amphenol RF and offers enhanced performance with 4 GHz maximum frequency (versus 2 GHz), extended operating temperature range (-65°C ~ 165°C versus -55°C ~ 85°C), and broader cable group compatibility. Insertion loss increases to 0.2 dB.

Q: Are both substitute parts RoHS compliant?

A: Yes. The 5221402-2 is RoHS Compliant, and the 031-71010 is ROHS3 Compliant. The original 221402-2 is RoHS non-compliant. Both substitutes meet current regulatory requirements.

Q: What cable types are compatible with these BNC connectors?

A: The 221402-2 and 5221402-2 are compatible with RG-59, 59A, and 59B cables. The 031-71010 supports a broader range including RG-59, 59B, 62, 140, 210, and Belden series 8241, 8263, 8279, 9209.

Q: Is the insertion loss difference between 0.15 dB and 0.2 dB significant?

A: The 0.05 dB difference between the 221402-2/5221402-2 (0.15 dB) and the 031-71010 (0.2 dB) represents a 33 percent increase in insertion loss. For applications operating at or near the 2 GHz frequency limit, this difference may be measurable. For lower frequency applications, the difference is typically negligible.

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

A: The 221402-2 and 5221402-2 operate from -55°C to 85°C. The 031-71010 operates from -65°C to 165°C, providing a 30°C lower minimum and 80°C higher maximum temperature capability.

Q: Are the connector packages identical across all three parts?

A: Yes. All three parts include 3 pieces: 1 connector, 1 contact, and 1 ferrule. The physical form factor and packaging are equivalent.

Q: What is the maximum frequency rating for each connector?

A: The 221402-2 and 5221402-2 are rated to 2 GHz maximum frequency. The 031-71010 is rated to 4 GHz maximum frequency, providing a 2 GHz performance margin for higher frequency applications.
