Substitute Part Grouping Explanation

Substitution eligibility for the 71922-020 is determined by strict alignment with the following core parameters: connector type (header), contact type (male pin), mating pitch (2.54mm), position count (20), row configuration (2 rows), mounting method (through-hole right-angle), termination (solder), fastening mechanism (push-pull), and shrouding design (4-wall). Mechanical compatibility requires matching contact length specifications and insulation height within acceptable tolerances. Electrical compatibility is maintained through equivalent contact material and finish specifications. All listed substitutes meet these criteria while accommodating variations in contact post length, contact material composition, and manufacturer-specific design implementations.

Engineering Selection Recommendations

The 71922-020LF represents the primary direct substitute, maintaining identical mechanical and electrical specifications while offering active product status and RoHS compliance. This part is recommended for new designs and production continuity where the original 71922-020 is no longer available.

For applications requiring alternative manufacturers, the 3M N3428-5002RB and D3428-5002-AR provide functionally equivalent solutions with ROHS3 compliance and active product status. Both parts maintain the critical 2.54mm pitch, 20-position, 2-row configuration with push-pull fastening and 4-wall shrouding. The N3428-5002RB offers standard contact post length (0.112"), while the N3428-5003RB provides extended post length (0.155") for applications requiring deeper PCB penetration.

The TE Connectivity 102159-4 (AMP-Latch series) and Amphenol ICC 8428162032035 (816 series) are functionally compatible alternatives. The 102159-4 features slightly reduced insulation height (0.315") and operates across -65°C to 105°C. The 8428162032035 uses 2-wall shrouding instead of 4-wall, which may affect mechanical fit in constrained applications.

For legacy system maintenance where RoHS compliance is not required, the original 71922-020 remains available in inventory (661 pcs) with identical specifications to the 71922-020LF.

Frequently Asked Questions (FAQ)

Q: Can the 71922-020LF be used as a direct replacement for the 71922-020?

A: Yes. The 71922-020LF maintains identical contact pitch (2.54mm), position count (20), row configuration (2), mounting type (through-hole right-angle), and shrouding (4-wall). The primary differences are product status (active vs. obsolete) and RoHS compliance. Mechanical and electrical compatibility is complete.

Q: What is the significance of the contact post length variation between N3428-5002RB (0.112") and N3428-5003RB (0.155")?

A: Contact post length determines PCB penetration depth during solder assembly. The N3428-5002RB (0.112") matches the original 71922-020 post length (0.114"), ensuring consistent solder joint formation. The N3428-5003RB (0.155") provides extended post length for applications requiring deeper through-hole engagement or thicker PCB assemblies.

Q: Why does the 8428162032035 use 2-wall shrouding instead of 4-wall?

A: The 816 series design uses 2-wall shrouding, which reduces overall connector profile but provides less mechanical protection. This may affect fit in applications designed for 4-wall shrouded connectors. Verify mechanical clearance before substitution.

Q: Are all substitute parts rated for the same operating temperature range?

A: No. The original 71922-020 and 71922-020LF do not specify operating temperature. The 102159-4 operates from -65°C to 105°C. The 3M parts (N3428-5002RB, N3428-5003RB, D3428-5002-AR) and 8428162032035 operate from -55°C to 105°C. Verify temperature requirements for your application.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates compliance with the updated RoHS 3 directive (2011/65/EU as amended). Both designations confirm absence of restricted substances. ROHS3 represents the current regulatory standard.

Q: Can the 102159-4 be used in applications designed for the 71922-020?

A: Mechanical compatibility exists for standard applications. However, the 102159-4 has slightly reduced insulation height (0.315" vs. 0.339") and different contact material (brass vs. phosphor bronze). Verify mechanical fit and electrical performance requirements before substitution.

Q: What packaging options are available for these substitute parts?

A: The 71922-020LF is supplied in tube packaging. The 102159-4 is supplied in bulk. The 8428162032035 packaging is not specified. The 3M parts (D3428-5002-AR, N3428-5002RB, N3428-5003RB) are supplied in tray and bulk configurations. Confirm packaging requirements for your procurement process.
