Amphenol ICC 76342-335 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76342-335 is a 70-position receptacle connector in the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This connector features through-hole solder termination, gold-plated mating contacts, and is rated for automotive, industrial, and telecommunications applications. The part is currently obsolete, making identification of suitable substitutes essential for ongoing system support and new designs requiring compatible interconnect solutions.

Substitute Part Grouping Explanation

Substitution for the 76342-335 is determined by strict alignment of electrical and mechanical parameters. The primary substitute is identified based on matching connector type, contact configuration, position count, pitch spacing, mounting method, and termination style.

Direct Substitute Criteria:

Connector Type: Receptacle
Contact Type: Female Socket
Number of Positions: 70
Pitch - Mating: 0.100" (2.54mm)
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole
Termination: Solder
Fastening Type: Push-Pull

Identified Substitute:

The part 76342-335LF meets all substitution criteria as a direct equivalent. This part maintains identical electrical and mechanical specifications while offering active product status and improved compliance characteristics.

The part 77313-801-28LF is listed in the original substitute field but does not meet substitution criteria due to fundamental differences in connector type (Header vs. Receptacle), contact type (Male Pin vs. Female Socket), and position count (28 vs. 70).

Engineering Selection Recommendations

The 76342-335LF is the appropriate substitute for the obsolete 76342-335. Both parts share identical electrical and mechanical specifications, ensuring direct compatibility in board-to-board interconnect applications. The primary distinction is product status: the 76342-335LF is active and carries RoHS compliance certification, whereas the original part is obsolete and RoHS non-compliant.

For new designs and ongoing production requiring 70-position receptacle connectors with 0.100" pitch spacing, the 76342-335LF provides continuity with enhanced regulatory compliance. The shift from REACH Unaffected to REACH Affected status reflects current regulatory alignment of the active part variant.

Packaging differs between the two parts: the original ships in bulk configuration while the substitute is supplied in tube packaging. This distinction affects handling and inventory management but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 76342-335LF directly replace the 76342-335 in existing designs?

A: Yes. The 76342-335LF maintains identical connector type, contact configuration, position count, pitch spacing, mounting method, and termination specifications. Physical and electrical compatibility is complete.

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

A: The "LF" suffix indicates lead-free compliance and RoHS certification. The 76342-335LF incorporates lead-free solder termination and meets RoHS requirements, whereas the original 76342-335 does not.

Q: Are there differences in contact finish between these parts?

A: No. Both parts feature identical gold plating on mating contacts (30.0µin thickness) and tin plating on posts (78.7µin thickness).

Q: Does packaging affect compatibility?

A: Packaging format (bulk vs. tube) affects handling, storage, and inventory management but does not impact electrical or mechanical compatibility. The connector specifications remain identical.

Q: What applications are these connectors suitable for?

A: Both parts are specified for automotive, general purpose, industrial, and telecommunications applications.

Q: Is the 77313-801-28LF a suitable alternative?

A: No. The 77313-801-28LF is a header connector with male pins and 28 positions, fundamentally different from the 70-position receptacle configuration. This part does not meet substitution criteria.
