Key Parameters

Substitute Part Grouping Explanation

Substitution of the 71922-426LF is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 26 positions in 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Orientation: Through-hole, right-angle mounting
• Shrouding Design: Shrouded 4-wall construction
• Termination Method: Solder termination
• Contact Materials & Finishes: Phosphor bronze with gold mating finish (GXT™) and tin post finish
• Insulation Properties: Thermoplastic, glass-filled material with UL94 V-0 rating
• Compliance Standards: RoHS compliance and MSL rating

The substitute part 71922-126LF maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 71922-126LF serves as the direct active equivalent for the obsolete 71922-426LF. Both components are manufactured by Amphenol ICC within the Quickie™ series and maintain identical electrical and mechanical specifications. The primary distinction is product status: the 71922-426LF is obsolete while the 71922-126LF is active and currently in production.

For new designs or ongoing procurement requirements, the 71922-126LF is the appropriate selection. Both parts carry RoHS compliance certification and MSL Level 1 rating, ensuring compatibility with modern manufacturing and storage requirements. The UL94 V-0 flammability rating is maintained across both variants.
