Key Parameters

Substitute Part Grouping Explanation

Substitution of the 71922-450LF is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (50)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Latch Lock/Eject Hooks)
• Contact materials and finishes (Phosphor Bronze with Gold GXT™ mating finish and Tin post finish)
• Insulation material (Thermoplastic, Glass Filled)
• Compliance certifications (UL94 V-0, RoHS Compliant)

The 71922-150LF meets all these criteria and is classified as an active product within the same Quickie™ series, providing direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 71922-150LF is the direct active equivalent for the obsolete 71922-450LF. Both components share identical electrical and mechanical specifications across all provided parameters. The primary distinction is product status: the 71922-450LF is obsolete, while the 71922-150LF maintains active production status within the Quickie™ series.

Both parts carry equivalent compliance certifications: UL94 V-0 flammability rating, RoHS compliance, and MSL 1 (Unlimited) moisture sensitivity classification. The 71922-150LF is available in tube packaging with higher inventory availability (1079 pieces in stock versus 748 pieces for the obsolete variant).

For new designs or component replenishment, the 71922-150LF is the appropriate selection. For legacy system maintenance requiring the exact original part number, the 71922-450LF remains available from existing inventory while supplies persist.

Frequently Asked Questions (FAQ)

Q: Are the 71922-450LF and 71922-150LF mechanically interchangeable?

A: Yes. Both components feature identical mounting configurations (through-hole, right-angle), shrouding design (4-wall), and contact spacing (0.100" / 2.54mm pitch with 0.100" row spacing). PCB footprints and mating interface dimensions are equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. The 71922-450LF is classified as obsolete, while the 71922-150LF is an active product. All electrical and mechanical parameters are identical. The 71922-150LF is supplied in tube packaging.

Q: Can I use the 71922-150LF as a direct replacement in existing assemblies designed for the 71922-450LF?

A: Yes. The 71922-150LF provides complete functional and mechanical compatibility with the 71922-450LF. No design modifications are required.

Q: Are both parts RoHS compliant?

A: Yes. Both the 71922-450LF and 71922-150LF are RoHS compliant with UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels.

Q: What is the contact finish specification for these headers?

A: Both parts feature gold GXT™ finish on mating contacts (30.0µin / 0.76µm thickness) and tin finish on solder posts (78.7µin / 2.00µm thickness). Contact material is phosphor bronze for both variants.
