Engineering Selection Recommendations

77313-124-22LF (Amphenol ICC - Direct Manufacturer Equivalent)

The 77313-124-22LF is the direct successor to the obsolete 77313-124-22, sharing identical BERGSTIK® series design and mechanical specifications. This part is currently in active production status with RoHS Compliant certification and REACH Affected status. The primary distinction is packaging format (Bulk versus original specification). This connector provides the highest compatibility assurance for direct replacement applications and is the preferred selection when maintaining legacy system designs.

1-87215-3 (TE Connectivity - Cross-Manufacturer Alternative)

The TE Connectivity 1-87215-3 from the AMPMODU Mod II series meets all critical electrical and mechanical substitution parameters. This part carries active product status with ROHS3 Compliant and REACH Affected certifications. Dimensional variations exist in contact length and insulation height specifications. This connector is suitable for applications where cross-manufacturer sourcing is acceptable and provides an alternative supply channel for the 22-position 2.54mm pitch header configuration.

BBD-111-T-B (Samtec - Alternative Supply Source)

The Samtec BBD-111-T-B from the BBD series satisfies core pitch, position count, and mounting requirements. This part maintains active product status with ROHS3 Compliant certification and REACH Unaffected status. Notable differences include insulation material composition (Polyester, Glass Filled versus Thermoplastic) and contact finish specifications. This connector provides a third-source option for applications requiring connector redundancy or supply chain diversification.

Frequently Asked Questions (FAQ)

Q: Can the 77313-124-22LF be used as a direct replacement for the obsolete 77313-124-22?

A: Yes. The 77313-124-22LF is the active production equivalent from Amphenol ICC, maintaining identical BERGSTIK® series specifications, pitch (2.54mm), position count (22), row configuration (2 rows), and core mechanical parameters. The primary difference is packaging format. This is the recommended substitution for legacy system support.

Q: What are the key differences between the Amphenol ICC 77313-124-22LF and the TE Connectivity 1-87215-3?

A: Both connectors share identical pitch (2.54mm), position count (22), row spacing (2.54mm), and mounting type (through-hole solder). Differences include: contact length (0.266" versus 0.318" mating contact), insulation height (0.100" versus 0.090"), contact shape (square versus circular), and operating temperature range (-65°C to 130°C versus -65°C to 105°C). The TE Connectivity part represents a cross-manufacturer alternative with slightly different physical dimensions.

Q: Are all three substitute parts RoHS compliant?

A: The 77313-124-22LF and 1-87215-3 are RoHS Compliant (RoHS3 for TE Connectivity). The BBD-111-T-B is ROHS3 Compliant. The original 77313-124-22 is RoHS non-compliant. For applications requiring RoHS compliance, all three substitutes are acceptable.

Q: What is the difference in packaging between these connectors?

A: The 77313-124-22LF is supplied in Bulk packaging. The 1-87215-3 is supplied in Bulk packaging. The BBD-111-T-B is supplied in Tube packaging. Packaging format does not affect electrical or mechanical compatibility; selection depends on inventory management and handling requirements.

Q: Can the BBD-111-T-B be used interchangeably with the Amphenol ICC connectors?

A: The BBD-111-T-B meets core substitution criteria (pitch, position count, row spacing, mounting type, and termination). However, it differs in insulation material (Polyester, Glass Filled versus Thermoplastic) and contact finish specifications. It is functionally compatible for applications where these material differences are acceptable. Verification of thermal and environmental requirements is necessary for specific applications.

Q: What is the significance of the REACH and RoHS status differences?

A: REACH Affected status indicates the part contains substances of concern requiring compliance documentation for European Union applications. REACH Unaffected status indicates no such substances are present. RoHS compliance indicates the part meets restrictions on hazardous substances. For applications subject to EU regulations, the 77313-124-22LF and 1-87215-3 (REACH Affected) require appropriate compliance documentation, while the BBD-111-T-B (REACH Unaffected) does not.

Q: Are there any operating temperature limitations when substituting these connectors?

A: The original 77313-124-22 does not specify an operating temperature range. The 77313-124-22LF operates from -65°C to 130°C, the 1-87215-3 from -65°C to 105°C, and the BBD-111-T-B from -55°C to 125°C. Selection should be based on the application's thermal requirements. The 77313-124-22LF provides the widest high-temperature capability.
