Engineering Selection Recommendations

Primary Substitute (Same Manufacturer): 191-037-223R001 from NorComp Inc. is the direct equivalent with identical electrical and mechanical specifications. This part maintains the same panel mount configuration, material composition, and operating temperature range. Selection of this part eliminates any cross-manufacturer compatibility considerations.

Secondary Substitutes (TE Connectivity AMP Connectors - AMPLIMITE Series): Parts 5745589-2, 5747713-2, 5747714-2, 5747715-2, and 747713-2 are functionally equivalent in core electrical parameters but feature through-hole mounting instead of panel mount. These parts are suitable for applications where PCB-mounted receptacles are acceptable. All TE Connectivity parts maintain UL94 V-0 flammability compliance and RoHS compliance status. Operating temperature range is -55°C ~ 105°C, which is 20°C lower than the primary part at the upper limit.

Tertiary Substitutes (Amphenol ICC / FCI - Delta D Series): Parts D37S91C4PA00LF, D37S91C4PL00LF, and D37S91C4PV00LF from Amphenol ICC (FCI) provide equivalent functionality with through-hole mounting. These parts maintain the full -55°C ~ 125°C operating temperature range and RoHS compliance. Shell material finish is tin-nickel plated, and dielectric material is polybutylene terephthalate (PBT). Current rating is specified at 5A per contact.

Compliance Considerations: All substitute parts listed maintain UL94 V-0 material flammability rating and RoHS compliance status. REACH compliance status varies across manufacturers and should be verified against specific supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute a through-hole mounted connector for the panel mount 191-037-222-001?

A: Through-hole mounted D-Sub connectors (5745589-2, 5747713-2, 5747714-2, 5747715-2, 747713-2, D37S91C4PA00LF, D37S91C4PL00LF, D37S91C4PV00LF) are electrically and mechanically equivalent but require different mechanical integration. Panel mount connectors are designed for mounting directly to an enclosure or panel, while through-hole connectors mount to a printed circuit board. Substitution is possible only if the application design permits PCB mounting instead of panel mounting.

Q: What is the difference between the NorComp 191-037-222-001 and 191-037-223R001?

A: Both parts are 37 position D-Sub receptacles from NorComp Inc. with identical electrical and mechanical specifications. The primary difference is packaging: 191-037-223R001 is supplied in tray packaging, while 191-037-222-001 packaging is not specified. Both maintain the same performance characteristics and are direct substitutes.

Q: Are TE Connectivity and Amphenol ICC connectors interchangeable with the NorComp part?

A: TE Connectivity (AMPLIMITE series) and Amphenol ICC (Delta D series) connectors are electrically and mechanically equivalent in core parameters: 37 positions, 2 rows, shell size 4, press-fit termination, and UL94 V-0 compliance. However, mounting type differs (through-hole versus panel mount). Physical integration into the application must be evaluated before substitution.

Q: What is the operating temperature difference between the primary part and TE Connectivity substitutes?

A: The 191-037-222-001 operates from -55°C to 125°C. TE Connectivity parts (5745589-2, 5747713-2, 5747714-2, 5747715-2, 747713-2) operate from -55°C to 105°C, a 20°C reduction at the upper temperature limit. Amphenol ICC parts (D37S91C4PA00LF, D37S91C4PL00LF, D37S91C4PV00LF) maintain the full -55°C to 125°C range. Application thermal requirements must be verified before selecting TE Connectivity alternatives.

Q: Do all substitute parts meet RoHS compliance?

A: All listed substitute parts are RoHS compliant. The primary part is ROHS3 compliant. TE Connectivity parts are marked as RoHS Compliant or ROHS3 Compliant. Amphenol ICC parts are RoHS Compliant. Part 747713-2 is marked as "Not Applicable" for RoHS status. Verify specific RoHS certification requirements for your supply chain before final part selection.

Q: What packaging options are available for these connectors?

A: Packaging formats include tray and bulk. Tray packaging is used for 191-037-223R001, 5745589-2, D37S91C4PA00LF, D37S91C4PL00LF, and D37S91C4PV00LF. Bulk packaging is used for 5745459-2, 5747713-2, 5747714-2, 5747715-2, and 747713-2. Packaging format does not affect electrical or mechanical function and is selected based on assembly process requirements.
