Amphenol ICC 76341-321 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76341-321 is a 21-position receptacle connector in the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts and tin-plated posts for reliable solder termination in automotive, industrial, telecommunications, and general-purpose applications.

The 76341-321 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for existing applications and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76341-321 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (21)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact finish specifications (Gold mating, Tin post)
• Insulation material and flammability rating (Thermoplastic, Glass Filled; UL94 V-0)
• Fastening mechanism (Push-Pull)

The substitute part 76341-321LF meets all these criteria, maintaining complete electrical and mechanical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The 76341-321LF is the direct substitute for the obsolete 76341-321. Both parts maintain identical electrical and mechanical specifications across all critical parameters, ensuring drop-in compatibility in existing designs.

The primary distinction between these parts is regulatory compliance status. The 76341-321LF carries RoHS Compliant certification, whereas the original 76341-321 is RoHS non-compliant. For new designs or applications subject to RoHS requirements, the 76341-321LF is the appropriate selection. For legacy systems or applications without RoHS mandates, both parts are functionally equivalent.

Packaging differs between the two parts: the 76341-321 is supplied in bulk format, while the 76341-321LF is packaged in tubes. This distinction affects inventory management and handling procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Are the 76341-321 and 76341-321LF electrically and mechanically interchangeable?

A: Yes. Both parts share identical specifications for connector type, contact configuration, pitch, mounting method, termination type, contact finishes, and all dimensional parameters. They are direct substitutes for board-to-board interconnect applications.

Q: What is the significance of the "LF" designation in the 76341-321LF part number?

A: The "LF" suffix indicates Lead-Free compliance, reflecting the part's RoHS Compliant status. The 76341-321LF meets lead-free material requirements, whereas the original 76341-321 does not.

Q: Can I use the 76341-321LF in applications originally designed for the 76341-321?

A: Yes. The 76341-321LF is a direct functional equivalent and can be used as a replacement in any application previously using the 76341-321. The RoHS Compliant status of the 76341-321LF makes it suitable for both legacy and new design requirements.

Q: Does the packaging difference between bulk and tube formats affect connector performance?

A: No. Packaging format is a supply and handling consideration only. The electrical and mechanical performance of the connector is identical regardless of whether it is supplied in bulk or tube packaging.

Q: What applications are these connectors suitable for?

A: The 76341-321 and 76341-321LF are designed for automotive, general-purpose, industrial, and telecommunications applications requiring 21-position board-to-board interconnection with 0.100" pitch and push-pull fastening.

Q: Are there any environmental or compliance considerations when selecting between these parts?

A: For applications subject to RoHS regulations or lead-free material requirements, the 76341-321LF is the required selection. Both parts meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, making them suitable for standard storage and handling conditions.
