Key Parameters

Substitute Part Grouping Explanation

Substitution of the 87606-418 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Position count (36 positions)
• Pitch spacing (0.100" / 2.54mm mating pitch and row spacing)
• Row configuration (2 rows)
• Mounting method (Through hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact geometry (Square shape, Phosphor Bronze material)
• Insulation specifications (Thermoplastic, Glass Filled, UL94 V-0)

The primary distinction between the main part and its substitute lies in contact finish composition and product status. The 87606-418 uses tin-lead finish and is obsolete, while the substitute employs tin finish and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The 87606-418LF serves as the direct substitute for the obsolete 87606-418. Both connectors maintain identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in board-to-board applications.

The 87606-418LF offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the 87606-418LF achieves RoHS compliance, whereas the original 87606-418 does not. The transition from tin-lead to tin contact finish in the 87606-418LF aligns with modern environmental and regulatory standards while maintaining the same contact finish thickness specification of 78.7µin (2.00µm).

Both parts retain UL94 V-0 material flammability rating, MSL 1 classification, and identical mechanical dimensions, confirming full functional equivalence for replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the 87606-418LF directly replace the 87606-418 in existing designs?

A: Yes. The 87606-418LF is mechanically and electrically equivalent to the 87606-418. Both connectors share identical pitch spacing (0.100"), position count (36), row configuration (2 rows), mounting method (through hole), and contact geometry (square phosphor bronze). The connectors are pin-for-pin compatible.

Q: What is the difference between the tin-lead finish of the 87606-418 and the tin finish of the 87606-418LF?

A: The primary difference is the contact finish composition. The 87606-418 uses tin-lead plating, while the 87606-418LF uses tin plating. Both maintain the same finish thickness of 78.7µin (2.00µm). The 87606-418LF's tin finish reflects compliance with RoHS regulations, whereas the 87606-418 is RoHS non-compliant.

Q: Why is the 87606-418 listed as obsolete?

A: The 87606-418 has been discontinued by the manufacturer. The 87606-418LF represents the active product line continuation within the Dubox™ series, offering equivalent functionality with updated compliance certifications.

Q: Are there packaging differences between these parts?

A: The 87606-418 packaging specification is not provided. The 87606-418LF is supplied in tube packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both connectors meet the same flammability and moisture sensitivity standards?

A: Yes. Both the 87606-418 and 87606-418LF are rated UL94 V-0 for material flammability and MSL 1 (Unlimited) for moisture sensitivity level, indicating equivalent environmental performance characteristics.
