Amphenol ICC 76341-405 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76341-405 is a 5-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications in automotive, industrial, telecommunications, and general purpose environments. This part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement planning. The connector features through-hole solder termination, tin-lead contact finish, and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76341-405 is determined by the following critical parameters:

• Connector Type & Contact Type: Must be receptacle with female socket contacts
• Number of Positions: Must be 5 positions
• Pitch - Mating: Must be 0.100" (2.54mm)
• Mounting Type: Must be through hole
• Termination: Must be solder
• Insulation Material: Must be thermoplastic, glass filled
• Material Flammability Rating: Must be UL94 V-0

The 76341-405LF qualifies as a direct substitute within the same Dubox™ series, differing only in contact finish composition (tin versus tin-lead) and RoHS compliance status. The 77313-120-06LF does not qualify as a substitute due to fundamental differences in connector type (header versus receptacle), contact type (male pin versus female socket), and number of positions (6 versus 5).

Parameter Comparison

Engineering Selection Recommendations

The 76341-405LF is the qualified substitute for the obsolete 76341-405. Both connectors maintain identical mechanical and electrical interface specifications within the Dubox™ series. The primary distinction is the contact finish composition: the 76341-405LF uses tin finish instead of tin-lead, and achieves RoHS compliance status. The 76341-405LF is currently in active production with higher inventory availability (1252 pcs versus 886 pcs for the original part).

The 77313-120-06LF is not suitable for direct substitution due to incompatible connector architecture (header versus receptacle), contact gender (male versus female), and position count (6 versus 5). This part belongs to a different connector family and would require complete circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the 76341-405LF be used as a direct replacement for the 76341-405?

A: Yes. The 76341-405LF maintains identical mating pitch (0.100"), position count (5), connector type (receptacle), contact type (female socket), mounting method (through hole), and termination (solder). The contact finish differs (tin versus tin-lead), and the substitute achieves RoHS compliance.

Q: Why is the 77313-120-06LF listed but not recommended as a substitute?

A: The 77313-120-06LF is a header connector with male pins and 6 positions, fundamentally incompatible with the 76341-405 receptacle design requiring female sockets and 5 positions. These are distinct connector families requiring different mating components.

Q: What is the impact of the contact finish change from tin-lead to tin in the 76341-405LF?

A: Both finishes provide equivalent contact thickness (78.7µin / 2.00µm) and maintain the same electrical and mechanical interface. The tin finish in the 76341-405LF enables RoHS compliance.

Q: Are there packaging differences between the main part and substitute?

A: Yes. The 76341-405 packaging is not specified, while the 76341-405LF is supplied in tube packaging. This affects procurement and handling procedures but does not impact electrical or mechanical compatibility.

Q: What is the inventory status for each part?

A: The 76341-405 (obsolete) has 886 pcs in stock. The 76341-405LF (active) has 1252 pcs in stock. The 77313-120-06LF (active) has 1105 pcs in stock.
