Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76342-316 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 32 positions in 2-row configuration
• Pitch Specification: 0.100" (2.54mm) mating pitch with matching row spacing
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Contact Material & Finish: Gold-plated mating surface with phosphor bronze base material
• Insulation Properties: Thermoplastic, glass-filled construction with UL94 V-0 rating

Direct Substitute (76342-316LF): Maintains identical electrical and mechanical specifications. The primary distinction is product status (active vs. obsolete) and RoHS compliance status.

Functional Alternative (77313-127-72LF): This header connector shares the 0.100" (2.54mm) pitch and through-hole solder termination but differs fundamentally in connector type (header vs. receptacle), contact gender (male pin vs. female socket), and position count (72 vs. 32). This part is not a direct substitute and requires mating interface redesign.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible Substitution):

The 76342-316LF is the appropriate selection for applications requiring functional equivalence to the obsolete 76342-316. Both parts maintain identical electrical and mechanical interfaces, connector geometry, and contact specifications. The 76342-316LF offers the advantage of active product status and RoHS compliance, making it suitable for new designs and systems requiring regulatory adherence. The transition from REACH Unaffected to REACH Affected status requires compliance verification within your supply chain documentation.

For System Redesign (Interface Modification Required):

The 77313-127-72LF is applicable only when system architecture permits connector type modification. This header connector introduces a male pin contact interface, requiring corresponding receptacle redesign on the mating assembly. The 72-position configuration necessitates PCB layout revision. This option is suitable for applications where connector standardization across multiple assemblies justifies redesign effort. The specified 3A per contact current rating and -65°C ~ 130°C operating temperature range should be evaluated against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 76342-316LF be used as a direct replacement for the 76342-316?

A: Yes. The 76342-316LF maintains identical pin count (32 positions), pitch (0.100"), row configuration (2 rows), contact type (female socket), and termination method (solder). Both parts are receptacle connectors with push-pull fastening and gold-plated mating contacts. Physical and electrical compatibility is confirmed.

Q: What is the significance of the "LF" suffix in the 76342-316LF part number?

A: The "LF" designation indicates lead-free construction and RoHS compliance. The 76342-316LF meets RoHS requirements, whereas the original 76342-316 does not. This distinction is critical for applications subject to RoHS regulations or customer specifications requiring lead-free components.

Q: Why is the 77313-127-72LF listed as a functional alternative rather than a direct substitute?

A: The 77313-127-72LF differs in three fundamental parameters: connector type (header vs. receptacle), contact gender (male pin vs. female socket), and position count (72 vs. 32). These differences require mating interface redesign and are not pin-compatible with existing 76342-316 receptacles. This part is suitable only for applications where system architecture modification is feasible.

Q: What packaging options are available for these parts?

A: The 76342-316 is supplied in standard packaging (not specified). The 76342-316LF is packaged in tubes. The 77313-127-72LF is supplied in bulk packaging. Packaging selection may affect procurement lead times and handling requirements.

Q: Are there operating temperature specifications for the 76342-316 and 76342-316LF?

A: Operating temperature is not specified for either the 76342-316 or 76342-316LF. The 77313-127-72LF specifies -65°C ~ 130°C operating range. For applications requiring temperature-dependent performance data, contact the manufacturer directly.

Q: What is the current rating for the 76342-316 and 76342-316LF?

A: Current rating is not specified for either part. The 77313-127-72LF specifies 3A per contact. For applications requiring current capacity verification, manufacturer documentation should be consulted.

Q: How do the RoHS and REACH compliance statuses differ between these parts?

A: The 76342-316 is RoHS non-compliant and REACH Unaffected. The 76342-316LF is RoHS Compliant and REACH Affected. The 77313-127-72LF is RoHS Compliant and REACH Affected. Selection should align with regulatory requirements applicable to your end application and geographic market.
