Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 71922-020LF is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - mating (0.100" / 2.54mm)
• Number of positions (20)
• Number of rows (2)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Material flammability rating (UL94 V-0)

Both identified substitute parts (D3428-5002-AR and N3428-5002RB) meet all critical parameter requirements. Variations in contact material, contact finish thickness, insulation material composition, and operating temperature specifications do not affect functional interchangeability within the defined connector category.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with RoHS and UL94 V-0 flammability requirements. The 71922-020LF, D3428-5002-AR, and N3428-5002RB are electrically and mechanically equivalent for board-to-cable/wire header applications with 20-position, 2.54mm pitch configurations.

Selection between these parts should be based on:

• Packaging requirements (Tube, Tray, or Bulk)
• Inventory availability and lead time
• Contact finish thickness specifications for your application
• Insulation material compatibility with your assembly process
• Operating temperature range requirements

The 3M D3428-5002-AR and N3428-5002RB both provide documented operating temperature ranges (-55°C to 105°C) and current ratings (1.75A), which may be advantageous for applications requiring explicit thermal and electrical performance specifications.

Frequently Asked Questions (FAQ)

Q: Can D3428-5002-AR or N3428-5002RB be used as direct replacements for 71922-020LF?

A: Yes. Both parts are functionally equivalent. They share identical connector type, contact type, pitch, position count, row configuration, mounting type, shrouding, termination method, and fastening type. Minor variations in contact material, contact finish thickness, and insulation material do not affect interchangeability within this connector category.

Q: What is the difference between D3428-5002-AR and N3428-5002RB?

A: Both are 3M 20-position, 2.54mm pitch right-angle headers with identical electrical and mechanical specifications. The primary differences are packaging format (Tray vs. Bulk) and contact finish thickness on the mating surface (10.0µin vs. 30.0µin). N3428-5002RB has thicker gold plating on mating contacts, matching the 71922-020LF specification.

Q: Does the difference in contact material (Phosphor Bronze vs. Brass vs. Copper Alloy) affect compatibility?

A: No. All three contact materials are acceptable for this connector category and do not affect functional interchangeability. Material selection is driven by manufacturing process and performance characteristics rather than compatibility requirements.

Q: Why do the substitute parts specify operating temperature and current ratings while the 71922-020LF does not?

A: The 3M parts provide explicit performance specifications. The absence of these specifications in the 71922-020LF datasheet does not indicate incompatibility; it reflects different documentation practices between manufacturers. All three parts are suitable for standard industrial and commercial applications.

Q: Does packaging format affect electrical performance?

A: No. Tube, Tray, and Bulk packaging formats are logistics and handling considerations only. They do not affect the electrical or mechanical performance of the connector header itself.

Q: Are there any compliance differences between these parts?

A: All three parts are RoHS compliant and UL94 V-0 rated. The 71922-020LF is RoHS Compliant; the 3M parts are ROHS3 Compliant. Both designations meet current regulatory requirements. The 71922-020LF is REACH Affected; N3428-5002RB is REACH Unaffected. Verify REACH status requirements for your specific application and region.
