Engineering Selection Recommendations
Direct Equivalents (Highest Compatibility):
The 172-037-183L021 from NorComp Inc. is the primary direct equivalent to the 172-037-182-021. Both parts share identical electrical and mechanical specifications, including 37 positions, panel mount configuration, steel nickel-plated shell, gold contact finish, 5A current rating, and -50°C to 125°C operating temperature range. Both are ROHS3 compliant. This part is recommended as the first choice for direct replacement.
The SDCB-37P(55) from Hirose Electric Co Ltd is functionally equivalent in connector style, position count, shell size, and mounting configuration. It features identical panel mount and through-hole capability with steel nickel-plated shell and gold contact finish. However, the current rating is 3A compared to 5A in the original part. This part is suitable for applications where current requirements do not exceed 3A and is RoHS compliant.
Compatible Alternatives (Extended Temperature Range):
HARTING parts 09654296701, 09654296702, 09654616711, 09654616712, 09664216701, 09664216703, and 09664217703 are compatible substitutes with extended operating temperature range (-55°C to 125°C versus -50°C to 125°C). These parts maintain the 37-position D-Sub configuration, shell size 4, solder termination, and UL94 V-0 flammability rating. Current ratings range from 6.5A to 7.5A, exceeding the original 5A specification. All HARTING parts are ROHS3 compliant. These parts are suitable for applications requiring enhanced temperature performance or higher current capacity.
Compliance Verification:
All substitute parts listed maintain ROHS3 compliance or equivalent RoHS compliance status, ensuring regulatory alignment with the original part. All parts are rated UL94 V-0 for material flammability, meeting safety requirements for industrial applications.
Frequently Asked Questions (FAQ)
Q: Can I use HARTING 09654296702 as a direct replacement for the NorComp 172-037-182-021?
A: Yes. Both connectors share the critical specifications: 37 positions, D-Sub style, shell size 4, solder termination, and UL94 V-0 rating. The HARTING part offers higher current capacity (6.5A vs. 5A) and extended temperature range (-55°C to 125°C vs. -50°C to 125°C), making it compatible for the same applications. Mounting type differs slightly (through-hole vs. panel mount), but both support through-hole installation.
Q: What is the difference between the NorComp 172-037-182-021 and 172-037-183L021?
A: These parts are functionally identical. Both are 37-position D-Sub plugs with male pins, panel mount configuration, solder termination, steel nickel-plated shells, and gold contact finish. The primary difference is packaging: 172-037-183L021 is supplied in trays, while 172-037-182-021 packaging is not specified. Both are ROHS3 compliant and suitable for direct substitution.
Q: Can I use the Hirose SDCB-37P(55) in place of the NorComp part?
A: The SDCB-37P(55) is mechanically and electrically compatible for most applications. It maintains the 37-position configuration, D-Sub style, panel mount capability, and solder termination. However, the current rating is 3A compared to 5A in the original part. Use this substitute only if your application current requirements do not exceed 3A. Operating temperature range is not specified for this part.
Q: Are all substitute parts ROHS compliant?
A: Yes. All listed substitute parts are either ROHS3 compliant or RoHS compliant, matching or exceeding the compliance status of the original NorComp 172-037-182-021 part.
Q: What are the key parameters I should verify before selecting a substitute?
A: Verify the following parameters match your application requirements: connector position count (37), connector type (plug with male pins), shell size (4), termination method (solder), current rating (minimum 5A for direct equivalence), and operating temperature range (minimum -50°C to 125°C). Confirm that mounting type (panel mount or through-hole) is compatible with your PCB or panel layout.
Q: Do HARTING parts with higher current ratings (6.5A or 7.5A) work in applications designed for 5A?
A: Yes. Higher current ratings indicate greater capacity and are backward compatible with applications designed for lower current ratings. The HARTING parts can safely operate in circuits requiring 5A or less. Select HARTING parts when higher current capacity or extended temperature range provides design margin for your application.
