Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 227676-2 is determined by strict equivalence across the following core parameters: connector style (BNC), connector type (jack, female socket), impedance (50 ohms), mounting configuration (panel mount, through hole, right angle with bulkhead front-side nut), contact and shield termination method (solder), fastening type (bayonet lock), maximum frequency (4 GHz), port count (1), voltage rating (500 V), and mating cycle rating (500). All identified substitute parts maintain these electrical and mechanical specifications. Variations in packaging format, center contact material composition, center contact plating, body material specification, dielectric material, operating temperature range, RoHS compliance status, and REACH classification do not preclude substitution when core parameters remain constant. The substitute parts are grouped into two categories: TE Connectivity AMP Connectors variants (5227661-1, 5227676-1, 5227677-1) and cross-manufacturer equivalent (031-6121 from Amphenol RF).

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the TE Connectivity 227676-2 across core functional parameters. Selection among substitutes should be based on compliance requirements and product status considerations.

TE Connectivity 5227676-1 is the direct parametric equivalent with RoHS compliance and REACH unaffected status. This part is suitable for applications requiring regulatory compliance with standard environmental directives while maintaining identical electrical specifications and gold-plated center contact.

TE Connectivity 5227677-1 provides ROHS3 compliance and REACH affected status with equivalent electrical performance and gold-plated center contact. This variant is available in higher inventory quantity (2402 pieces) compared to the main part.

TE Connectivity 5227661-1 offers ROHS3 compliance and REACH affected status with tin-plated center contact instead of gold plating. This part is available in significantly higher inventory (210158 pieces) and packaged in tube format, suitable for high-volume applications where center contact plating material variation is acceptable.

Amphenol RF 031-6121 is a cross-manufacturer equivalent from Amphenol RF with ROHS3 compliance and REACH affected status. This part features beryllium copper center contact material, PTFE dielectric material, and extended operating temperature range (-65°C ~ 165°C). The 031-6121 includes specified insertion loss of 0.2 dB and includes three components (connector, lockwasher, nut) per unit. This option is suitable for applications requiring extended temperature performance or cross-manufacturer sourcing strategy.

The original TE Connectivity 227676-2 is RoHS non-compliant with vendor-undefined REACH status. Applications subject to RoHS or REACH regulatory requirements must transition to one of the compliant substitute parts.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5227661-1 substitute for the 227676-2 if center contact plating differs?

A: Yes. The 5227661-1 with tin-plated center contact is electrically and mechanically equivalent to the 227676-2 across all core parameters including impedance, frequency rating, voltage rating, and mating cycles. Center contact plating material does not affect substitution eligibility for these specifications.

Q: What is the primary difference between the TE Connectivity variants (5227661-1, 5227676-1, 5227677-1)?

A: The three TE Connectivity variants differ in packaging format, center contact plating, and regulatory compliance status. The 5227661-1 is tube-packaged with tin plating. The 5227676-1 is bulk-packaged with gold plating and RoHS compliance. The 5227677-1 is bulk-packaged with gold plating and ROHS3 compliance. All three maintain identical electrical and mechanical specifications.

Q: Is the Amphenol RF 031-6121 suitable for the same applications as the TE Connectivity 227676-2?

A: The 031-6121 is electrically and mechanically equivalent across core parameters. However, it features different center contact material (beryllium copper versus phosphor bronze), different dielectric material (PTFE versus PMP), extended operating temperature range (-65°C ~ 165°C versus -55°C ~ 85°C), and specified insertion loss of 0.2 dB. These differences do not preclude substitution but should be evaluated against specific application requirements.

Q: Does the inclusion of lockwasher and nut with the Amphenol RF 031-6121 affect substitution compatibility?

A: No. The 031-6121 includes three components (connector, lockwasher, nut) as standard. The TE Connectivity 227676-2 mounting feature specification (bulkhead front-side nut) indicates nut inclusion is standard for this connector type. The additional lockwasher component does not affect electrical or mechanical compatibility.

Q: Which substitute part should be selected for RoHS-compliant applications?

A: Three substitute parts meet RoHS compliance requirements: TE Connectivity 5227676-1 (RoHS Compliant), TE Connectivity 5227677-1 (ROHS3 Compliant), and Amphenol RF 031-6121 (ROHS3 Compliant). The 5227676-1 is additionally REACH unaffected, making it suitable for applications with both RoHS and REACH requirements.

Q: What packaging options are available among the substitute parts?

A: The TE Connectivity 5227661-1 is supplied in tube packaging. The TE Connectivity 5227676-1 and 5227677-1 are supplied in bulk packaging. The Amphenol RF 031-6121 is supplied in bulk packaging. Packaging selection should align with procurement and assembly process requirements.

Q: Can the 227676-2 be used interchangeably with the 5227661-1 in existing designs?

A: Yes, within the constraints of regulatory compliance. Both parts are electrically and mechanically equivalent across all core parameters. The 5227661-1 is ROHS3 compliant and REACH affected, whereas the 227676-2 is RoHS non-compliant. If the design or application is subject to RoHS or REACH regulations, the 5227661-1 is the appropriate substitute.
