Key Parameters

Substitute Part Grouping Explanation

Substitution for the 87606-433LF is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle
• Number of positions: 66
• Pitch specification: 0.100" (2.54mm) mating pitch with 0.100" row spacing
• Number of rows: 2
• Mounting configuration: Through-hole solder termination
• Fastening mechanism: Push-pull
• Insulation material and flammability: Thermoplastic glass-filled, UL94 V-0
• Contact geometry: Square phosphor bronze contacts
• Series compatibility: Dubox™

The primary distinction among qualified substitutes is the contact finish specification on mating surfaces. The 87606-433LF uses tin finish (78.7µin/2.00µm), while alternative configurations within the same series may employ gold finish (30.0µin/0.76µm) for enhanced corrosion resistance and contact reliability in demanding environments.

Parameter Comparison

Engineering Selection Recommendations

The 87606-333LF serves as the direct substitute for the obsolete 87606-433LF. Both connectors maintain identical mechanical and electrical interface specifications within the Dubox™ series, ensuring mechanical and functional compatibility in board-to-board applications.

The 87606-333LF is currently in active production status with established inventory availability, addressing the obsolescence of the original part. The substitute incorporates gold plating on mating contacts (30.0µin/0.76µm) compared to the tin finish of the original specification. Gold contact finish provides enhanced resistance to oxidation and corrosion, particularly beneficial in automotive and industrial environments subject to thermal cycling and moisture exposure.

The 87606-333LF carries RoHS compliance and REACH compliance certifications, meeting current regulatory requirements for electronic components in regulated markets. Both parts maintain UL94 V-0 flammability ratings and identical moisture sensitivity classifications.

Frequently Asked Questions (FAQ)

Q: Are the 87606-433LF and 87606-333LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 66 positions, 0.100" (2.54mm) pitch, 2-row configuration, through-hole mounting, and push-pull fastening. Physical dimensions, insulation height (0.335"), and contact post length (0.114") are identical.

Q: What is the functional difference between these connectors?

A: The primary difference is the contact finish on mating surfaces. The 87606-433LF uses tin finish (78.7µin/2.00µm), while the 87606-333LF uses gold finish (30.0µin/0.76µm). Gold finish provides superior corrosion resistance and contact reliability in harsh environments.

Q: Can I use the 87606-333LF as a direct replacement for the 87606-433LF in existing designs?

A: Yes. The connectors are functionally equivalent for board-to-board applications. The gold contact finish of the substitute offers equivalent or improved performance characteristics compared to the tin finish of the original part.

Q: What is the packaging difference between these parts?

A: The 87606-433LF packaging information is not specified in available documentation. The 87606-333LF is supplied in tube packaging.

Q: Are there compliance differences between these connectors?

A: The 87606-333LF carries RoHS and REACH compliance certifications. Both parts maintain UL94 V-0 flammability ratings and identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Why is the 87606-433LF obsolete?

A: Product obsolescence is determined by manufacturer production decisions. The 87606-333LF represents the active production equivalent within the Dubox™ series.
