87606-339LF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 87606-339LF is a 78-position receptacle connector manufactured by Amphenol ICC (FCI) in the Dubox™ series. This board-to-board connector features 0.100" (2.54mm) pitch through-hole solder termination with gold-plated mating contacts and push-pull fastening. The part is currently obsolete, making identification of active equivalent components essential for ongoing production support, maintenance, and design continuity.

Substitute Part Grouping Explanation

The 76342-339LF qualifies as a direct substitute for the 87606-339LF based on the following critical parameters:

Connector Type & Contact Configuration: Both are 78-position female socket receptacles
Pitch & Spacing: Identical 0.100" (2.54mm) mating pitch and row spacing
Electrical Interface: Both feature phosphor bronze contacts with gold mating finish (30.0µin thickness) and tin post finish (78.7µin thickness)
Mounting & Termination: Both use through-hole solder termination with push-pull fastening
Material & Compliance: Both employ thermoplastic glass-filled insulation with UL94 V-0 flammability rating
Series Compatibility: Both belong to the Dubox™ connector series

The primary distinction is product status: 87606-339LF is obsolete, while 76342-339LF is active with current inventory availability.

Engineering Selection Recommendations

The 76342-339LF is the direct active equivalent for the obsolete 87606-339LF. Both connectors share identical electrical and mechanical specifications across all critical mating and termination parameters. The substitute part maintains full compatibility with existing PCB layouts and mating components.

Two dimensional differences exist: the 76342-339LF has a reduced insulation height (0.275" versus 0.335") and increased mated stacking height (11.04mm versus 9.54mm). These variations are within the Dubox™ series design envelope and do not affect electrical performance or contact integrity.

The 76342-339LF offers additional compliance documentation: RoHS Compliant status and REACH Affected designation, providing enhanced regulatory traceability for modern supply chain requirements. Both parts carry identical MSL 1 (Unlimited) moisture sensitivity classification and EAR99 export control designation.

Frequently Asked Questions (FAQ)

Q: Can the 76342-339LF directly replace the 87606-339LF in existing designs?

A: Yes. Both connectors are 78-position Dubox™ receptacles with identical 0.100" pitch, contact materials, finishes, and solder termination. PCB footprints and mating interfaces are compatible.

Q: What is the significance of the insulation height difference?

A: The 76342-339LF has 0.060" lower insulation height (0.275" versus 0.335"). This is a dimensional variation within the Dubox™ series and does not affect electrical performance or contact engagement. Verify clearance in applications with height-constrained layouts.

Q: Does the increased mated stacking height affect compatibility?

A: The 76342-339LF mated stacking height is 1.50mm greater (11.04mm versus 9.54mm). This reflects the reduced insulation height and does not alter electrical characteristics. Confirm available stacking space in board-to-board applications.

Q: What compliance advantages does the 76342-339LF provide?

A: The 76342-339LF carries explicit RoHS Compliant and REACH Affected designations. Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Q: Is packaging different between these parts?

A: The 76342-339LF is supplied in tube packaging. Original packaging specification for the 87606-339LF was not documented. Confirm packaging requirements for your procurement process.

Q: Are there any electrical performance differences?

A: No. Both connectors use phosphor bronze contacts with identical gold mating finish (30.0µin) and tin post finish (78.7µin). Contact length, material composition, and electrical interface are identical.
