Substitute Part Grouping Explanation

Substitution of the 87606-403 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for connector type, position count, pitch, row configuration, mounting method, termination style, fastening mechanism, contact geometry, and insulation properties.

The primary distinction between the main part and its substitute relates to contact finish composition and product status. The 87606-403 uses tin-lead contact finish and is classified as obsolete. The substitute part 87606-403LF employs tin contact finish (lead-free) and maintains active product status.

Key parameters governing substitution:

Connector type: Receptacle
Position configuration: 6 positions, 2 rows, 0.100" pitch
Mounting and termination: Through-hole solder
Fastening: Push-pull mechanism
Contact geometry and material: Square phosphor bronze contacts
Insulation specifications: Thermoplastic glass-filled, UL94 V-0 rated

Engineering Selection Recommendations

The 87606-403LF serves as the direct substitute for the obsolete 87606-403. Both parts maintain identical mechanical and electrical interface specifications, ensuring mechanical and electrical compatibility in board-to-board applications.

The 87606-403LF is classified as an active product with RoHS compliance and REACH affected status, providing regulatory alignment with current environmental and hazardous substance directives. The transition from tin-lead to tin contact finish reflects industry-standard lead-free manufacturing practices while maintaining equivalent contact performance and reliability characteristics.

Selection of the 87606-403LF is appropriate for new designs, production continuity, and system maintenance where the 87606-403 is no longer available through standard supply channels.

Frequently Asked Questions (FAQ)

Q: Are the 87606-403 and 87606-403LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, pitch, row spacing, mounting type, and fastening mechanism. They are directly interchangeable in board-to-board applications.

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

A: The 87606-403 uses tin-lead contact finish, while the 87606-403LF uses tin (lead-free) contact finish. Both maintain the same contact finish thickness of 78.7µin (2.00µm). The lead-free composition of the 87606-403LF aligns with RoHS compliance requirements.

Q: Why is the 87606-403 classified as obsolete?

A: The 87606-403 has reached end-of-life status. The 87606-403LF represents the active product continuation within the Dubox™ series, incorporating lead-free manufacturing standards.

Q: Does the 87606-403LF meet RoHS requirements?

A: Yes. The 87606-403LF is RoHS compliant. The 87606-403 is RoHS non-compliant due to its tin-lead contact finish.

Q: Are there packaging differences between these parts?

A: The 87606-403 packaging is not specified in available documentation. The 87606-403LF is supplied in tube packaging.

Q: Can the 87606-403 and 87606-403LF be used in the same circuit board design?

A: Yes. The identical electrical and mechanical specifications ensure functional equivalence. Design changes are not required when transitioning from the 87606-403 to the 87606-403LF.
