76342-435LF Equivalent & Substitute Parts

Part Overview

The 76342-435LF is a 70-position receptacle connector from the Dubox™ series manufactured by Amphenol ICC (FCI). This board-to-board rectangular connector features a 0.100" (2.54mm) pitch, through-hole solder termination, and tin-plated mating contacts. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support, maintenance, and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76342-435LF is determined by the following critical parameters that must remain constant:

• Connector type: Receptacle
• 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
• Insulation material: Thermoplastic, glass filled
• Contact shape: Square
• Contact material: Phosphor bronze
• Series: Dubox™

The 76342-335LF qualifies as a direct substitute based on these parameters. The primary difference is the contact finish on mating surfaces: the 76342-435LF uses tin plating (78.7µin / 2.00µm), while the 76342-335LF uses gold plating (30.0µin / 0.76µm). Both maintain identical mechanical and electrical interface specifications, allowing functional interchangeability in applications where the connector footprint and pin configuration are the determining factors.

Parameter Comparison

Engineering Selection Recommendations

The 76342-335LF serves as the active production equivalent to the obsolete 76342-435LF. Both connectors maintain identical mechanical and electrical interface specifications within the Dubox™ series. The 76342-335LF is currently in active production status with RoHS compliance certification and REACH compliance documentation, making it suitable for new designs and ongoing system support where the 76342-435LF is no longer available.

The contact finish difference (tin versus gold) reflects the primary distinction between these parts. The 76342-335LF's gold-plated mating contacts provide enhanced corrosion resistance and contact reliability compared to the tin-plated contacts of the 76342-435LF. Both finishes are applied to phosphor bronze contact substrates with identical post-side tin plating.

Selection between these parts should be based on application requirements, regulatory compliance mandates, and supply chain availability. The 76342-335LF is the recommended choice for new implementations due to its active product status and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 76342-335LF directly replace the 76342-435LF in existing applications?

A: Yes. Both connectors share identical mechanical dimensions, pin configurations, pitch specifications, and mounting characteristics. The 70-position, 0.100" pitch, two-row through-hole receptacle interface is functionally equivalent between the two parts.

Q: What is the significance of the contact finish difference between these parts?

A: The 76342-435LF features tin-plated mating contacts, while the 76342-335LF features gold-plated mating contacts. Gold plating provides superior corrosion resistance and contact reliability in environments with moisture, temperature cycling, or corrosive atmospheres. Tin plating is suitable for controlled indoor environments with stable conditions.

Q: Why is the 76342-435LF listed as obsolete?

A: The 76342-435LF has been discontinued by the manufacturer. The 76342-335LF represents the active production alternative within the Dubox™ series, offering improved contact finish specifications and current compliance certifications.

Q: Are there any compliance differences between these parts?

A: The 76342-335LF carries RoHS Compliant and REACH Affected certifications. Compliance documentation for the 76342-435LF is not specified in available technical data. For applications requiring regulatory compliance verification, the 76342-335LF is the appropriate selection.

Q: What is the packaging difference between these parts?

A: The 76342-435LF packaging specification is not provided. The 76342-335LF is supplied in tube packaging. Confirm packaging requirements with your procurement specifications.

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

A: Yes. Both the 76342-435LF and 76342-335LF are specified for automotive, general purpose, industrial, and telecommunications applications. The identical application range reflects their functional equivalence within the Dubox™ connector series.
