76342-445LF Equivalent & Substitute Parts

Part Overview

The 76342-445LF is a 90-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 76342-445LF is determined by strict alignment of the following critical parameters:

• Connector Type & Style: Must be receptacle, board-to-board configuration
• Position Count & Pitch: Must maintain 90 positions at 0.100" (2.54mm) mating pitch with 2 rows at 0.100" (2.54mm) row spacing
• Mounting & Termination: Must support through-hole solder termination
• Physical Compatibility: Insulation height (0.275"), contact length (0.114"), and mated stacking height (11.04mm) must remain consistent
• Contact Material & Finish: Phosphor bronze contacts with tin or gold plating are acceptable; contact finish thickness variations are permissible within industry standards

The 76342-345LF qualifies as a direct substitute based on these parameters. The primary difference is the contact finish specification: 76342-345LF features gold-plated mating contacts (30.0µin) versus tin-plated contacts (78.7µin) on the 76342-445LF. Both maintain identical mechanical and electrical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 76342-345LF is the qualified substitute for the obsolete 76342-445LF. Selection between these parts should be based on the following criteria:

Use 76342-345LF when:

• Active product support and availability are required
• RoHS compliance is mandated (76342-345LF is RoHS Compliant)
• REACH compliance is required (76342-345LF is REACH Affected)
• Gold-plated contacts provide enhanced corrosion resistance for the application environment
• New designs or system updates are being implemented

Use 76342-445LF only when:

• Exact original component replacement is necessary for legacy systems
• Tin-plated contact finish is specifically required by design specification
• Inventory of the original part is available

Both parts maintain identical mechanical interfaces, electrical characteristics, and physical dimensions. The transition from tin to gold plating represents an upgrade in contact durability and environmental resistance.

Frequently Asked Questions (FAQ)

Q: Can 76342-345LF be used as a direct replacement for 76342-445LF in existing designs?

A: Yes. Both connectors maintain identical mechanical and electrical interfaces. The 90-position configuration, 0.100" pitch, through-hole solder termination, and physical dimensions are identical. The primary difference is the contact finish material.

Q: What is the significance of the contact finish difference between tin and gold plating?

A: Contact finish affects corrosion resistance and long-term reliability. Gold plating (76342-345LF) provides superior protection against oxidation and environmental degradation compared to tin plating (76342-445LF). Both finishes are suitable for standard industrial applications.

Q: Are there compliance differences between these two parts?

A: Yes. The 76342-345LF is RoHS Compliant and REACH Affected, while the 76342-445LF (obsolete) does not list these certifications. For applications requiring regulatory compliance, 76342-345LF is the appropriate selection.

Q: What is the packaging difference?

A: The 76342-345LF is supplied in Tube packaging. Packaging specifications for 76342-445LF were not provided in the original documentation.

Q: Are both parts available for purchase?

A: The 76342-445LF is obsolete and availability is limited to existing inventory (1146 pcs reported in stock). The 76342-345LF is an active product with current inventory (747 pcs reported in stock).

Q: Do these connectors support the same mating partner components?

A: Yes. Both receptacles are designed for the same Dubox™ series plug connectors with matching 90-position, 0.100" pitch configuration.
