Engineering Selection Recommendations

Selection of substitute rectangular connectors for obsolete Amphenol ICC (FCI) 68645-008 is based on part status and compliance. The direct substitute, Amphenol ICC (FCI) 68645-008LF, is active and RoHS compliant, providing a matched specification within the same manufacturer and series. TE Connectivity AMP Connectors 103167-7 is also active and fulfills required functional parameters. RoHS and compliance status should be considered for applications where regulatory requirements are in effect.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters governing connector substitution in this product category?
A1: Substitution requires matching connector type, contact type, pitch, number of positions and rows, row spacing, mounting style, shrouding, termination method, fastening, and material flammability rating.

Q2: Do all substitute parts maintain the same mechanical interface as the obsolete part?
A2: All listed alternatives share identical core mechanical parameters: 20 positions, 2.54mm pitch, shrouded, through-hole, right angle, detent lock, and appropriate row spacing.

Q3: Is insulation material or color a factor in substitution?
A3: All substitutes feature black insulation with material flammability rated to UL94 V-0, fulfilling category requirements.

Q4: How do differences in RoHS status affect selection?
A4: The substitute 68645-008LF is RoHS compliant. The 103167-7’s RoHS status is not applicable. Selection is determined by specific application requirements regarding compliance.

Q5: Does packaging variation affect interchangeability?
A5: Packaging (Bulk vs. Tray) does not affect electrical or mechanical compatibility and can be selected based on logistics and assembly preference.

Q6: Are there dimensional differences to consider in post or mating lengths?
A6: Differences are minimal. Both substitutes align closely with main part dimensions within the category tolerances.

Q7: Can the manufacturer’s recommended alternative be used in designs originally intended for Amphenol ICC (FCI)?
A7: When specified parameters match, cross-manufacturer substitution is permitted for rectangular connectors of standardized formats.
