Key Parameters

Substitute Part Grouping Explanation

Substitution of the 71922-434LF is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 34 positions in 2-row arrangement
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole, right-angle solder termination
• Shrouding Design: Shrouded 4-wall construction with keying slot and mounting flange
• Contact Materials & Finishes: Phosphor bronze with gold-plated mating surface (GXT™) and tin-plated posts
• Insulation Properties: Thermoplastic, glass-filled material with UL94 V-0 rating
• Compliance: RoHS compliant, MSL 1 (Unlimited)

The substitute part 71922-134LF maintains identical electrical and mechanical specifications across all these parameters, with the primary distinction being product status (Active vs. Obsolete) and packaging format (Tube vs. unspecified for the original).

Parameter Comparison

Engineering Selection Recommendations

The 71922-134LF is a direct functional equivalent to the 71922-434LF. Both parts are manufactured by Amphenol ICC within the Quickie™ series and share identical electrical, mechanical, and compliance specifications. The primary distinction is product lifecycle status: the 71922-434LF is obsolete while the 71922-134LF maintains active production status.

For new designs or ongoing procurement, the 71922-134LF is the appropriate selection. Both parts maintain RoHS compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. The substitute part is available in tube packaging, which is standard for production quantities.

Frequently Asked Questions (FAQ)

Q: Can the 71922-134LF be used as a direct replacement for the 71922-434LF in existing designs?

A: Yes. The 71922-134LF is electrically and mechanically identical to the 71922-434LF. All contact configurations, pitch specifications, mounting geometry, and material properties are equivalent. The parts are interchangeable at the board level.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 71922-434LF is classified as obsolete, indicating discontinued production. The 71922-134LF is in active production, ensuring long-term availability and supply chain continuity. For new designs or replenishment, the active part number should be specified.

Q: Are there any differences in contact finish or material composition?

A: No. Both parts feature phosphor bronze contacts with identical gold plating (GXT™) on mating surfaces at 30.0µin thickness and tin plating on posts at 78.7µin thickness. Contact material and insulation composition are identical.

Q: Does packaging format affect electrical or mechanical performance?

A: No. The 71922-134LF is supplied in tube packaging, which is a standard distribution format. Packaging does not affect connector performance, contact integrity, or compliance certifications. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Are both parts RoHS compliant?

A: Yes. Both the 71922-434LF and 71922-134LF are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.
