Amphenol ICC 76341-407 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76341-407 is a 7-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications using through-hole solder termination. This connector features tin-lead contact finish and is part of the Dubox™ series. The main part is currently obsolete, making identification of suitable substitutes necessary for ongoing system support and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 76341-407 is based on maintaining electrical and mechanical compatibility across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts ensures mating compatibility with existing plug connectors
• Position Count & Pitch: 7 positions at 0.100" (2.54mm) spacing maintains PCB layout compatibility
• Mounting & Termination: Through-hole solder termination preserves assembly process compatibility
• Mechanical Form Factor: Board-to-board style with push-pull fastening ensures mechanical interchangeability
• Series Designation: Dubox™ series classification confirms design family compatibility

The substitute part 76341-407LF meets all these criteria while offering updated compliance status and active product availability.

Parameter Comparison

Engineering Selection Recommendations

The 76341-407LF is the direct substitute for the obsolete 76341-407. Both connectors share identical mechanical and electrical specifications across all critical parameters including position count, pitch, mounting type, and contact configuration.

The primary distinction is product status and regulatory compliance. The 76341-407LF is an active product with RoHS compliance, whereas the original 76341-407 is obsolete and RoHS non-compliant. The contact finish differs from tin-lead to tin, which is consistent with RoHS compliance requirements and maintains electrical performance within the specified parameters.

For new designs or replacement applications, the 76341-407LF is the appropriate selection. For legacy systems requiring the exact tin-lead finish specification, the original 76341-407 remains available in current inventory (1170 pcs), though its obsolete status should be considered in long-term supply planning.

Frequently Asked Questions (FAQ)

Q: Are the 76341-407 and 76341-407LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, mounting type (through-hole), pitch (0.100"), position count (7), and form factor (board-to-board). They are directly interchangeable in PCB layouts.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 76341-407 uses tin-lead contact finish, while the 76341-407LF uses tin finish. Both finishes provide equivalent electrical performance and contact resistance. The tin finish on the 76341-407LF reflects RoHS compliance requirements.

Q: Can I use the 76341-407LF as a replacement in existing designs using the 76341-407?

A: Yes. The 76341-407LF is electrically and mechanically compatible with the 76341-407. The contact finish change from tin-lead to tin does not affect functional performance in standard applications.

Q: Why is the 76341-407 listed as obsolete?

A: The 76341-407 is obsolete due to its RoHS non-compliant status. The 76341-407LF represents the current active product line for this connector configuration.

Q: What packaging is available for the 76341-407LF?

A: The 76341-407LF is supplied in tube packaging, with 777 pcs currently in stock.

Q: Are both parts suitable for automotive, industrial, and telecommunications applications?

A: Yes. Both the 76341-407 and 76341-407LF are rated for automotive, general purpose, industrial, and telecommunications applications.
