Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5747252-4 (Direct Manufacturer Substitute)

The 5747252-4 is the primary substitute option. This part is manufactured by TE Connectivity, the same manufacturer as the main part, and maintains identical electrical and mechanical specifications including 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. The primary difference is packaging format (Tray versus Bulk) and RoHS3 compliance certification. The 5747252-4 is suitable for applications requiring ROHS3 compliance documentation and offers higher inventory availability (2762 pieces).

NorComp 174-E37-113R001 (Alternative Manufacturer Substitute)

The 174-E37-113R001 provides substitution from an alternative manufacturer with active product status. This part maintains the 37-position, 2-row D-Sub plug configuration with solder termination and UL94 V-0 flammability rating. Notable differences include reduced current rating (5A versus 6A), unthreaded flange feature, nickel-plated shell finish, and slightly different backset spacing (0.370" versus 0.318"). Operating temperature range is -50°C to 100°C, which is narrower than the main part. This substitute is appropriate for applications with lower current requirements and where nickel plating is acceptable.

NorComp 182-037-113R171 (Alternative Manufacturer Substitute)

The 182-037-113R171 provides substitution from NorComp with matching backset spacing (0.318") and operating temperature range (-55°C to 105°C) to the main part. This connector features a 4-40 threaded flange, ground strap, and grounding indents identical to the main part. The primary limitation is reduced current rating (5A versus 6A) and nickel-plated shell finish. This substitute is appropriate for applications with lower current requirements and where the matching backset spacing and temperature range are critical.

All substitute parts maintain active product status and are manufactured by established connector suppliers with ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can the 5747252-4 be used as a direct replacement for the 747252-4?

A: Yes. The 5747252-4 is electrically and mechanically equivalent to the 747252-4. Both parts are manufactured by TE Connectivity, feature identical 37-position D-Sub plug configuration, 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. The primary difference is packaging format (Tray versus Bulk). The 5747252-4 includes ROHS3 compliance certification.

Q: What are the limitations of the NorComp 174-E37-113R001 as a substitute?

A: The 174-E37-113R001 has a reduced current rating of 5A compared to the 6A rating of the main part. The operating temperature range is narrower (-50°C to 100°C versus -55°C to 105°C). The backset spacing is 0.370" instead of 0.318", which may affect PCB layout compatibility. The flange feature is unthreaded rather than 4-40 threaded. These differences require verification against application requirements before substitution.

Q: What are the limitations of the NorComp 182-037-113R171 as a substitute?

A: The 182-037-113R171 has a reduced current rating of 5A compared to the 6A rating of the main part. The shell material finish is nickel-plated rather than tin-plated. These differences require verification against application requirements before substitution. The backset spacing (0.318") and operating temperature range (-55°C to 105°C) match the main part.

Q: Are all substitute parts RoHS compliant?

A: The main part 747252-4 has RoHS status listed as "Not applicable." All three substitute parts (5747252-4, 174-E37-113R001, and 182-037-113R171) are ROHS3 compliant. Applications requiring RoHS compliance documentation should specify one of the substitute parts.

Q: What is the difference between Bulk and Tray packaging?

A: The main part 747252-4 is supplied in Bulk packaging with 690 pieces in stock. The substitute parts are supplied in Tray packaging with higher inventory levels (2762 pieces for 5747252-4, 1282 pieces for 174-E37-113R001, and 962 pieces for 182-037-113R171). Tray packaging provides better organization and handling for automated assembly processes.

Q: Can the NorComp parts be used in high-current applications?

A: The NorComp parts (174-E37-113R001 and 182-037-113R171) are rated for 5A maximum current, compared to 6A for the TE Connectivity parts. Applications requiring 6A current capacity must use either the main part 747252-4 or the substitute 5747252-4.

Q: Are there differences in contact material between the substitute parts?

A: The main part 747252-4 and substitute 5747252-4 specify brass contact material. The 174-E37-113R001 does not specify contact material in the provided data. The 182-037-113R171 specifies brass contact material. All parts feature gold contact finish.

Q: What is the significance of the flange feature differences?

A: The main part 747252-4 and substitute 182-037-113R171 feature 4-40 threaded flanges for secure mounting with fasteners. The substitute 174-E37-113R001 features an unthreaded flange. The flange configuration affects mechanical mounting and should be verified against application requirements.

Q: Do all parts meet the same flammability standards?

A: Yes. All four parts (747252-4, 5747252-4, 174-E37-113R001, and 182-037-113R171) meet UL94 V-0 material flammability rating, indicating compliance with flame propagation requirements.

Q: What is the difference in shell material finish between the parts?

A: The main part 747252-4 and substitute 5747252-4 feature tin-plated steel shells. The NorComp substitutes (174-E37-113R001 and 182-037-113R171) feature nickel-plated steel shells. Shell material finish affects corrosion resistance and environmental performance characteristics.
