Amphenol ICC 76342-408 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76342-408 is a 16-position receptacle connector from the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This connector features through-hole solder termination with tin-lead contact finish and is rated for automotive, general purpose, industrial, and telecommunications applications.

The 76342-408 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production and maintenance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 76342-408 is determined by strict alignment with the following critical parameters:

Connector type: Receptacle
Contact type: Female socket
Position count: 16 positions
Pitch spacing: 0.100" (2.54mm) mating pitch with 0.100" (2.54mm) row spacing
Mounting configuration: Through-hole solder termination
Fastening mechanism: Push-pull
Insulation material: Thermoplastic, glass-filled
Flammability rating: UL94 V-0
Mated stacking height: 11.04mm
Series family: Dubox™

The substitute part 76342-408LF meets all these criteria. The primary difference is the contact finish specification: the substitute uses tin finish on both mating and post contacts, whereas the original part specifies tin-lead finish. This represents a material composition change while maintaining equivalent electrical and mechanical performance within the established parameter set.

Engineering Selection Recommendations

The 76342-408LF serves as the direct substitute for the obsolete 76342-408. Both parts maintain identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in board-to-board applications.

The 76342-408LF carries active product status, providing assured long-term availability and supply chain continuity. The substitute achieves RoHS compliance through its tin contact finish specification, whereas the original tin-lead finish does not meet RoHS requirements. For applications subject to RoHS regulations or environmental compliance mandates, the 76342-408LF is the appropriate selection.

Both parts are rated for automotive, general purpose, industrial, and telecommunications applications with UL94 V-0 flammability certification and unlimited moisture sensitivity level (MSL 1).

Frequently Asked Questions (FAQ)

Q: Are the 76342-408 and 76342-408LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing (0.100"), row configuration (2 rows), position count (16), mounting type (through-hole), and fastening mechanism (push-pull). They are pin-for-pin compatible for board-to-board applications.

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

A: The original 76342-408 uses tin-lead plating on both mating and post contacts. The substitute 76342-408LF uses tin plating. Both maintain the same contact finish thickness (78.7µin / 2.00µm). The tin finish in the 76342-408LF enables RoHS compliance.

Q: Can I use the 76342-408LF in applications originally designed for the 76342-408?

A: Yes, provided your application does not have specific requirements for tin-lead contact finish. The electrical and mechanical performance characteristics are equivalent. If your design specifies tin-lead finish for particular environmental or performance reasons, consult your design documentation before substitution.

Q: Why is the original 76342-408 marked as obsolete?

A: The 76342-408 is obsolete due to the industry transition toward RoHS-compliant components. The 76342-408LF represents the current active equivalent within the Dubox™ series.

Q: What packaging is available for the 76342-408LF?

A: The 76342-408LF is supplied in tube packaging, whereas packaging information for the original 76342-408 was not specified.

Q: Are there any compliance differences I should consider?

A: The 76342-408LF is RoHS compliant and REACH affected, whereas the original 76342-408 is RoHS non-compliant and REACH unaffected. For applications in regulated markets or subject to environmental directives, the 76342-408LF is the required selection.
