Key Parameters

Substitute Part Grouping Explanation

Substitution for the 76347-303 is determined by the following critical parameters:

• Contact type: Socket
• Termination method: Crimp
• Wire gauge compatibility: 22-30 AWG
• Contact finish: Gold plating
• Series compatibility: DUBOX™, MezzSelect™, Basics+

The primary substitute, 76347-303LF, maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications. This part is functionally equivalent and represents the direct successor in the product line.

The secondary substitute, 77313-824-14LF, operates under different mechanical and electrical parameters (header connector, through-hole termination, 14-position configuration) and is not a direct functional equivalent. This part is listed as an alternative contact option only and requires design verification for compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the 76347-303, the 76347-303LF is the recommended direct substitute. Both parts share identical electrical and mechanical specifications, including wire gauge, contact finish, and termination method. The 76347-303LF offers the advantage of active product status and RoHS compliance, making it suitable for new designs and long-term procurement strategies.

The 76347-303LF transitions from REACH Unaffected to REACH Affected status, requiring compliance verification within your supply chain documentation if REACH compliance is a design requirement.

The 77313-824-14LF is not recommended as a direct substitute due to fundamental differences in connector type (header vs. socket contact), termination method (solder vs. crimp), and series designation (BERGSTIK® vs. DUBOX™/MezzSelect™/Basics+). Selection of this part requires complete design re-evaluation and is applicable only to applications with different mechanical and electrical requirements.

Frequently Asked Questions (FAQ)

Q: Can 76347-303LF be used as a direct replacement for 76347-303?

A: Yes. The 76347-303LF maintains identical specifications for wire gauge (22-30 AWG), contact termination (crimp), contact finish (gold at 30.0µin thickness), and series designation. The primary difference is product status (active vs. obsolete) and improved compliance certifications.

Q: What is the significance of the "LF" suffix in 76347-303LF?

A: The "LF" designation indicates lead-free compliance and RoHS compliance status. This part meets current environmental and regulatory requirements for electronic component manufacturing.

Q: Is 77313-824-14LF compatible with designs using 76347-303?

A: No. The 77313-824-14LF operates under different mechanical and electrical parameters. It is a header connector with solder termination and 14-position configuration, whereas the 76347-303 is a socket contact with crimp termination. These parts serve different connector applications and are not interchangeable.

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

A: The 76347-303LF is available in Cut Tape (CT) packaging. The 77313-824-14LF is available in Bulk packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Are there compliance differences between 76347-303 and 76347-303LF?

A: Yes. The 76347-303 is RoHS non-compliant and REACH Unaffected. The 76347-303LF is RoHS Compliant and REACH Affected. For applications requiring RoHS or REACH compliance, the 76347-303LF is the appropriate selection.

Q: What is the current inventory status for these parts?

A: The 76347-303 (obsolete) has 788 pieces in stock. The 76347-303LF (active) has 4594 pieces in stock. The 77313-824-14LF has 1114 pieces in stock. Inventory levels should be verified with your supplier for current availability.
