Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76347-401 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Socket contact type (not pin)
• 22-30 AWG wire gauge accommodation
• Crimp termination method
• Tin or tin-lead contact finish
• DUBOX™, MezzSelect™, or Basics+ series membership

Regulatory Considerations:

• RoHS compliance status
• REACH applicability
• Moisture sensitivity level alignment

The substitute parts listed maintain functional equivalence through matching wire gauge, contact type, and termination method. Variations in contact finish composition and thickness, as well as product status transitions from obsolete to active, are documented to support engineering decision-making.

Parameter Comparison

Engineering Selection Recommendations

76347-401LF represents the primary direct substitute for 76347-401. Both components maintain identical wire gauge (22-30 AWG), socket contact type, crimp termination, and series designation. The transition from tin-lead to tin finish and reduced contact finish thickness (78.7µin versus 196.9µin) reflects modern manufacturing standards. Critically, 76347-401LF achieves RoHS compliance and active product status, addressing the obsolescence of the original part while maintaining functional compatibility within the DUBOX™, MezzSelect™, and Basics+ connector families.

77315-101-36LF is a fundamentally different component architecture. This part functions as a header connector with male pins, solder termination, and 36-position configuration. It is not a direct socket contact substitute but rather a board-level connector component from the BERGSTIK® series. Selection of this part requires system-level redesign and is appropriate only when connector topology and termination methodology can be modified.

For applications requiring socket contacts with crimp termination and 22-30 AWG wire gauge accommodation, 76347-401LF is the appropriate selection. For applications requiring header connectors with through-hole solder termination, 77315-101-36LF may be considered within the context of complete connector assembly redesign.

Frequently Asked Questions (FAQ)

Q: Can 76347-401LF directly replace 76347-401 in existing assemblies?

A: Yes, for applications where RoHS compliance is acceptable or required. Both parts maintain socket contact type, 22-30 AWG wire gauge, crimp termination, and series membership. The contact finish change from tin-lead to tin and reduced finish thickness do not affect functional compatibility in standard rectangular connector applications.

Q: What is the significance of the "LF" designation in 76347-401LF?

A: The "LF" suffix indicates lead-free composition, reflecting RoHS compliance. This part is manufactured to eliminate lead content while maintaining electrical and mechanical performance equivalent to the original tin-lead version.

Q: Is 77315-101-36LF suitable as a substitute for 76347-401?

A: No. The 77315-101-36LF is a header connector with male pins and solder termination, fundamentally different from the 76347-401 socket contact with crimp termination. These components serve different connector architectures and cannot be interchanged without complete system redesign.

Q: What packaging options are available for substitute parts?

A: 76347-401LF is supplied in Cut Tape (CT) packaging. 77315-101-36LF is supplied in Bulk packaging. Packaging selection should align with assembly process requirements and inventory management protocols.

Q: Are there compliance differences between 76347-401 and 76347-401LF?

A: Yes. 76347-401 is RoHS non-compliant and REACH Unaffected. 76347-401LF is RoHS Compliant and REACH Affected. For applications subject to RoHS or REACH regulations, 76347-401LF is the required selection.
