Parameter Comparison

Engineering Selection Recommendations

Both DLS4SS5AN21X and 189-037-513R571 are active products with ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current applications. Both conform to UL94 V-0 flammability requirements and support identical operating temperature ranges.

Selection between these parts depends on specific mounting geometry requirements:

• Select DLS4SS5AN21X when board edge mounting is required or when the 3A current rating is sufficient for the application.
• Select 189-037-513R571 when panel mount configuration is necessary or when the higher 5A current rating is required.

The 0.004" (0.10mm) difference in backset spacing and variance in shell plating material (tin versus nickel) should be evaluated against application-specific environmental exposure and mating cycle durability requirements.

Frequently Asked Questions (FAQ)

Q: Are DLS4SS5AN21X and 189-037-513R571 electrically compatible? A: Both connectors are 37-position D-Sub stacked receptacles with identical pin configurations, operating temperatures, and gold-flashed contacts. They are electrically compatible, provided the current rating and voltage requirements of the application do not exceed the component specifications.

Q: What is the primary functional difference between these two parts? A: The primary difference is mounting type. DLS4SS5AN21X provides board edge mounting, while 189-037-513R571 provides panel mount configuration. The DLS4SS5AN21X is rated for 3A maximum current; the 189-037-513R571 is rated for 5A. Shell plating differs (tin versus nickel).

Q: Can I substitute 189-037-513R571 for DLS4SS5AN21X in an existing design without modification? A: Substitution requires design review. The panel mount configuration of 189-037-513R571 may not be compatible with a board edge mounting application without mechanical rework. The higher current rating of 189-037-513R571 does not require design change, but the mounting type difference is critical for installation compatibility.

Q: What does ROHS3 compliance mean for these connectors? A: ROHS3 compliance indicates both components meet the Restriction of Hazardous Substances Directive, restricting use of specified hazardous materials in electrical equipment. Both parts meet this regulatory requirement for EU and similar markets.

Q: Is packaging type a consideration when selecting between these alternatives? A: Yes. DLS4SS5AN21X is supplied in bulk packaging; 189-037-513R571 is supplied in tray packaging. Packaging selection may affect receiving, storage, and assembly handling procedures based on organizational logistics requirements.
