Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS and UL94 V-0 flammability requirements, ensuring regulatory alignment with the original 171-015-212-021 specification.

Panel Mount Configuration: Parts 171-015-213R021, 628-015-320-017, and SDAB-15S(55) provide panel mount options matching the original mounting style. The 171-015-213R021 is a direct NorComp variant with identical electrical ratings (5A current).

Through-Hole Vertical Mount Configuration: Parts D15S24A6RX09LF, DLS2XS4AA35X, and DLS2XS4AA39X offer vertical through-hole mounting with reduced current ratings (3A to 5A per contact). These variants include additional features such as board lock or female screwlock mechanisms.

Shell Finish Variation: DLS2XS4AA35X and DLS2XS4AA39X feature tin-plated steel shells instead of nickel plating, with equivalent gold contact finish and UL94 V-0 compliance.

Current Rating Consideration: The original part supports 5A current. Substitutes 628-015-320-017, DLS2XS4AA35X, DLS2XS4AA39X, and SDAB-15S(55) are rated at 3A per contact, suitable for lower-current signal applications.

Frequently Asked Questions (FAQ)

Q: Can 171-015-213R021 be used as a direct replacement for 171-015-212-021?

A: Yes. Both parts are manufactured by NorComp Inc., share the same 15-position, 2-row DA/A configuration, and support 5A current with solder termination. The primary difference is packaging (tray vs. standard). Electrical and mechanical compatibility is confirmed.

Q: What is the difference between panel mount and through-hole vertical mount variants?

A: Panel mount connectors (171-015-212-021, 171-015-213R021, 628-015-320-017, SDAB-15S(55)) are designed for mounting on panel surfaces with flange features. Through-hole vertical mount variants (D15S24A6RX09LF, DLS2XS4AA35X, DLS2XS4AA39X) are oriented vertically on PCBs. Mounting type selection depends on application layout requirements.

Q: Are tin-plated and nickel-plated shells interchangeable?

A: Both finishes provide corrosion resistance and meet UL94 V-0 flammability requirements. Tin plating (DLS2XS4AA35X, DLS2XS4AA39X) and nickel plating (171-015-212-021, 171-015-213R021, 628-015-320-017, SDAB-15S(55)) are functionally equivalent for signal applications. Selection may depend on environmental exposure and cost considerations.

Q: What is the significance of the 3A vs. 5A current rating difference?

A: The original 171-015-212-021 supports 5A per contact. Substitutes rated at 3A per contact are suitable for applications with lower current requirements. For applications requiring 5A per contact, use 171-015-213R021 or D15S24A6RX09LF.

Q: Can solder paste termination (D15S24A6RX09LF) be used in place of standard solder termination?

A: Solder paste termination is compatible with automated assembly processes. D15S24A6RX09LF maintains the same 15-position, 2-row configuration and gold contact finish. Termination method selection depends on assembly process compatibility.

Q: What additional features do DLS2XS4AA35X and DLS2XS4AA39X provide?

A: DLS2XS4AA35X includes board lock feature. DLS2XS4AA39X includes both board lock and female screwlock (4-40) on the mating side. These features provide mechanical retention and secure mating. Both maintain full electrical and mechanical compatibility with the 15-position, 2-row DA/A specification.

Q: Are all substitute parts ROHS3 compliant?

A: Six of seven substitutes are ROHS3 compliant (171-015-213R021, 628-015-320-017, DLS2XS4AA35X, DLS2XS4AA39X). D15S24A6RX09LF and SDAB-15S(55) are RoHS Compliant. All meet regulatory requirements for lead-free applications.
