626-037-562-012 D-Sub 37 Position Receptacle Equivalent & Substitute Parts

Part Overview

The 626-037-562-012 is a 37 position D-Sub receptacle connector manufactured by Mercury United Electronics, Inc. This panel mount, through-hole, right-angle solder connector features female sockets with gold-plated phosphor bronze contacts and a nickel-plated steel shell. The connector is actively produced and ROHS3 compliant, designed for applications requiring reliable signal transmission in industrial and commercial environments. Equivalent and substitute parts are identified when component availability changes, supply chain disruptions occur, or design flexibility is needed while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 626-037-562-012 is determined by strict adherence to the following core parameters: 37 position count, D-Sub receptacle configuration with female sockets, shell size 4 (DC, C), panel mount through-hole right-angle orientation, solder termination, and UL94 V-0 flammability rating. All identified substitutes maintain these critical parameters. Variations in contact material (phosphor bronze versus brass), contact finish thickness (10.0µin versus flash), shell finish (nickel plated versus tin plated), dielectric material composition, flange features, and operating temperature ranges are permitted within the substitution framework. Current rating tolerance extends from 5A to 6A. Backset spacing variation from 0.590" (14.99mm) to 0.454" (11.53mm) is acceptable for through-hole mounting applications. Packaging format differences (bulk versus tray) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and meet UL94 V-0 flammability requirements. The 183-037-213R171 and 183-037-213R541 from NorComp Inc. are ROHS3 compliant and support extended operating temperatures to 105°C compared to the primary part's 85°C maximum. The 183-037-213R171 features a ground strap, while the 183-037-213R541 includes board lock functionality on the mating side. The 5745441-4 from TE Connectivity AMP Connectors provides a 6A current rating, exceeding the 5A specification of the primary part, and includes mounting brackets. All substitutes are RoHS compliant and REACH unaffected. Selection should be based on specific application requirements regarding operating temperature range, flange feature necessity, and current capacity needs.

Frequently Asked Questions (FAQ)

Q: Can 183-037-213R171 replace 626-037-562-012 in existing designs? A: Yes. Both connectors share identical 37 position count, shell size 4 (DC, C), panel mount through-hole right-angle configuration, and solder termination. The NorComp part supports higher operating temperatures (-55°C to 105°C versus -55°C to 85°C) and includes a ground strap feature. Contact material differs (brass versus phosphor bronze) and contact finish is flash gold rather than 10.0µin plating, but both maintain gold contact finish and UL94 V-0 compliance.

Q: What are the differences between 183-037-213R171 and 183-037-213R541? A: Both are NorComp 37 position D-Sub receptacles with identical electrical specifications. The primary difference is the flange feature: 183-037-213R171 has a housing/shell (4-40) flange, while 183-037-213R541 features a mating side female screwlock (4-40) with board lock functionality. The 183-037-213R541 also specifies MSL 1 (Unlimited) moisture sensitivity versus not applicable for the 183-037-213R171.

Q: Is the 5745441-4 suitable as a substitute? A: Yes, with considerations. The TE Connectivity part maintains 37 position count, shell size 4 (DC, C), right-angle solder configuration, and UL94 V-0 compliance. It provides 6A current capacity versus 5A and supports -55°C to 105°C operating range. Differences include tin-plated steel shell (versus nickel plated), mounting brackets inclusion, and backset spacing of 0.454" (11.53mm) versus 0.590" (14.99mm). Panel mount designation is not specified for this part.

Q: Does packaging format affect compatibility? A: No. The 626-037-562-012 is supplied in bulk packaging, while NorComp substitutes are supplied in trays and the TE Connectivity part in bulk. Packaging format does not affect electrical or mechanical connector performance or interchangeability.

Q: Are all substitutes ROHS compliant? A: Yes. The 626-037-562-012, 183-037-213R171, and 183-037-213R541 are ROHS3 compliant. The 5745441-4 is RoHS compliant. All parts are REACH unaffected and carry EAR99 ECCN classification.
