Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility):

The part number 5747238-6 from TE Connectivity AMP Connectors is a direct equivalent to 747238-6. Both parts share identical electrical and mechanical specifications, including 6A current rating, 125V voltage rating, mating side female screwlock flange configuration, and operating temperature range of -55°C to 105°C. The primary distinction is that 5747238-6 carries RoHS Compliant status, whereas 747238-6 is RoHS non-compliant. Inventory availability for 5747238-6 is 2351 pieces, providing superior supply continuity.

HARTING Alternatives (09683637813 for Flange Match):

The HARTING part number 09683637813 provides functional equivalence with the following considerations: it features a mating side female screwlock flange matching the 747238-6 configuration, operates across -55°C to 125°C (extended upper temperature limit), and carries ROHS3 Compliant status. Current rating is 6.5A, exceeding the 6A specification. The connector uses copper alloy contacts rather than brass. This part is suitable for applications requiring RoHS compliance and extended temperature operation.

HARTING Alternative (09683635812 for Housing/Shell Flange):

The HARTING part number 09683635812 features a housing/shell flange configuration with 4-40 threading. This part is not a direct mechanical substitute for 747238-6 due to flange feature differences but provides electrical equivalence with 6.5A current rating and ROHS3 Compliant status.

NorComp Alternatives (182 Series):

The NorComp 182 series connectors (182-025-113R161, 182-025-113R171, 182-025-113R181, 182-025-113R531) provide functional alternatives with the following constraints: current rating is 5A (lower than the 6A specification of 747238-6), and mounting type includes panel mount capability in addition to through-hole. All NorComp parts carry ROHS3 Compliant status. The 182-025-113R181 matches the mating side female screwlock flange configuration. The 182-025-113R531 offers the highest inventory availability at 10,862 pieces.

Mercury United Electronics Alternatives (621 Series):

The Mercury 621 series connectors (621-025-260-011 and 621-025-260-012) are not recommended as primary substitutes due to significantly reduced current rating (3A per contact versus 6A) and lower maximum operating temperature (85°C versus 105°C). These parts are suitable only for applications with reduced current and temperature requirements.

Compliance Considerations:

Applications requiring RoHS compliance must select from 5747238-6, HARTING 09683635812, 09683637813, or NorComp 182 series parts. The original 747238-6 is RoHS non-compliant and REACH Affected.

Frequently Asked Questions (FAQ)

Q: Can 5747238-6 be used as a direct replacement for 747238-6?

A: Yes. The 5747238-6 is electrically and mechanically identical to 747238-6, with the same 6A current rating, 125V voltage rating, mating side female screwlock flange, and -55°C to 105°C operating temperature range. The primary difference is RoHS compliance status. Both parts are suitable for identical applications.

Q: What is the significance of the flange feature in selecting a substitute?

A: The flange feature determines the mechanical mounting interface. The 747238-6 uses a mating side female screwlock (4-40) flange, which interfaces with mating connectors equipped with corresponding male screwlock pins. Substitutes with different flange configurations (housing/shell or unthreaded) are not mechanically compatible with equipment designed for the 747238-6 flange type.

Q: Are HARTING 09683635812 and 09683637813 interchangeable with 747238-6?

A: The HARTING 09683637813 is mechanically compatible with 747238-6 due to matching mating side female screwlock flange configuration. The HARTING 09683635812 has a different flange type (housing/shell) and is not mechanically compatible. Both HARTING parts exceed the current rating specification (6.5A versus 6A) and extend the operating temperature range to 125°C.

Q: Why do NorComp 182 series parts have a lower current rating than 747238-6?

A: The NorComp 182 series is specified at 5A current rating, which is lower than the 747238-6 specification of 6A. This difference reflects design variations in contact geometry and material composition. Applications requiring the full 6A rating must use parts specified at 6A or higher.

Q: Can Mercury 621 series connectors substitute for 747238-6?

A: Mercury 621 series connectors are not suitable substitutes for 747238-6 in applications requiring the full electrical specifications. The 621 series is rated at 3A per contact (half the 6A rating of 747238-6) and operates to a maximum of 85°C (versus 105°C for 747238-6). These parts are appropriate only for lower-current, lower-temperature applications.

Q: What packaging differences exist among the substitute parts?

A: The 747238-6 and 5747238-6 are supplied in tray packaging. HARTING parts (09683635812, 09683637812, 09683637813) are supplied in bulk packaging. NorComp 182 series parts are supplied in tray packaging. Mercury 621 series parts are supplied in bulk packaging. Packaging affects handling, storage, and ordering quantities but does not affect electrical or mechanical compatibility.

Q: Are all substitute parts RoHS compliant?

A: No. The original 747238-6 is RoHS non-compliant. The 5747238-6 is RoHS Compliant. All HARTING parts are ROHS3 Compliant. All NorComp 182 series parts are ROHS3 Compliant. All Mercury 621 series parts are ROHS3 Compliant. Applications subject to RoHS requirements must exclude 747238-6 and select from compliant alternatives.

Q: What is the difference between "Mating Side, Female Screwlock" and "Housing/Shell" flange features?

A: "Mating Side, Female Screwlock (4-40)" indicates that the flange is located on the mating face of the connector and features female threaded holes for 4-40 screws, allowing mechanical coupling to mating connectors with corresponding male screwlock pins. "Housing/Shell" flanges are located on the connector body and are used for panel mounting or board edge mounting. These are mechanically incompatible configurations.

Q: Can 747238-6 be used in applications requiring extended temperature operation beyond 105°C?

A: No. The 747238-6 is specified for -55°C to 105°C operation. Applications requiring operation to 125°C must use HARTING 09683635812 or 09683637813, which are rated to -55°C to 125°C.
