Amphenol ICC 76347-402 Socket Contact Rectangular Connector

Part Overview

The 76347-402 is a socket contact for rectangular connectors manufactured by Amphenol ICC (FCI), designed for wire gauges 22-30 AWG with crimp termination. This component is part of the DUBOX™, MezzSelect™, and Basics+ series. The part is currently obsolete, which necessitates identification of active equivalent alternatives to maintain supply chain continuity for applications requiring this contact type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76347-402 is determined by the following critical parameters that must remain constant:

• Manufacturer and Series: Amphenol ICC (FCI) DUBOX™, MezzSelect™, Basics+ series
• Contact Type: Socket configuration
• Termination Method: Crimp termination
• Wire Gauge Compatibility: 22-30 AWG
• Base Product Number: 76347 family

The 76347-402LF qualifies as a direct substitute based on matching all functional and mechanical parameters. The primary differences are contact finish composition (Tin vs. Tin-Lead), finish thickness, packaging format, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 76347-402LF is the active equivalent for the obsolete 76347-402. Selection between these parts should be based on the following factors:

For new designs and applications requiring regulatory compliance: The 76347-402LF is the appropriate choice. It maintains RoHS compliance and is an active product with established supply availability (30,758 pcs in stock). The REACH Affected status indicates compliance with current environmental regulations.

For legacy system maintenance: The 76347-402 remains available in limited inventory (1,053 pcs) if exact historical specifications are required, though its obsolete status and RoHS non-compliant designation make it unsuitable for new applications.

Contact finish considerations: The 76347-402LF uses pure Tin finish (78.7µin / 2.00µm thickness) compared to the Tin-Lead finish (196.9µin / 5.00µm thickness) of the 76347-402. Both finishes are suitable for crimp termination on 22-30 AWG wire within the DUBOX™, MezzSelect™, and Basics+ connector series.

Packaging format: The 76347-402LF is supplied in Cut Tape (CT) format, while the original 76347-402 was supplied in Tape & Reel (TR) format. Packaging selection should align with assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the 76347-402LF be used as a direct replacement for the 76347-402?

A: Yes. Both parts are socket contacts within the same Amphenol ICC series, support identical wire gauges (22-30 AWG), use crimp termination, and share the same base product number (76347). Functional compatibility is maintained across applications using these connector series.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: The contact finish affects corrosion resistance and solderability characteristics. The 76347-402LF uses pure Tin finish with reduced thickness (2.00µm), while the 76347-402 uses Tin-Lead with greater thickness (5.00µm). Both finishes are appropriate for crimp-terminated contacts in this product category.

Q: Why is the 76347-402 listed as obsolete?

A: Product obsolescence reflects manufacturing discontinuation. The 76347-402LF represents the current active product line for this contact type and should be specified for all new applications.

Q: Does the packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats are logistics and assembly considerations only. Electrical and mechanical specifications remain identical. Packaging selection should align with manufacturing equipment and assembly processes.

Q: What is the importance of RoHS compliance in this substitution?

A: RoHS compliance is a regulatory requirement for products sold in many markets. The 76347-402LF meets RoHS standards, while the 76347-402 does not. For applications subject to RoHS regulations, the 76347-402LF is the required choice.

Q: Are there inventory implications for this substitution?

A: The 76347-402LF has significantly higher inventory availability (30,758 pcs) compared to the 76347-402 (1,053 pcs). For ongoing production requirements, the 76347-402LF provides superior supply chain stability.
