Engineering Selection Recommendations

For Direct Receptacle Substitution:

The 3M 150250-2020-RB-WF offers the closest functional match to the Molex 0791098674. Both parts feature board guide and pick-and-place capabilities for automated assembly. The 3M part provides higher voltage rating (500VDC vs. 125V) and UL94 V-0 flammability certification, making it suitable for applications requiring enhanced electrical performance and safety compliance. Operating temperature range is reduced to -55°C ~ 105°C compared to the Molex specification of -55°C ~ 125°C.

The 3M 150250-2000-RB (Bulk packaging) provides identical electrical and mechanical specifications to the 150250-2020-RB-WF but without board guide features, suitable for manual assembly workflows.

The Amphenol ICC 55510-150TRLF (Minitek® 2.00mm series) maintains the full operating temperature range (-55°C ~ 125°C) and provides higher current rating (2A vs. 1A). This part includes UL94 V-0 flammability rating and is suitable for general purpose, industrial, and medical applications.

For Header/Receptacle Mating Pairs:

The Sullins Connector Solutions NPPN252FFKS-RC and NPPN252FFKP-RC are header connectors designed to mate with 50-position, 0.079" (2.00mm) pitch receptacles. These parts are suitable for board-to-board interconnect applications where a mating header is required. Both feature ROHS3 compliance and UL94 V-0 flammability rating. Operating temperature range is -40°C ~ 105°C. The NPPN252FFKP-RC includes board guide features; the NPPN252FFKS-RC does not.

Compliance Considerations:

All substitute parts maintain RoHS compliance. The Molex 0791098674 and Sullins parts are ROHS3 compliant. The 3M and Amphenol ICC parts are RoHS compliant. All parts are REACH unaffected and carry EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the 3M 150250-2000-RB be used as a direct replacement for the Molex 0791098674?

A: Yes, for applications operating within -55°C ~ 105°C and 125V or lower. The 3M part provides higher voltage rating (500VDC) and UL94 V-0 flammability certification. The primary difference is packaging (Bulk vs. Tape & Reel) and absence of board guide features in the 150250-2000-RB variant.

Q: What is the difference between the 3M 150250-2000-RB and 150250-2020-RB-WF?

A: Both are 3M 1502 series receptacles with identical electrical specifications. The 150250-2020-RB-WF includes board guide and pick-and-place features and is supplied in Cut Tape packaging. The 150250-2000-RB is supplied in Bulk packaging without board guide features. Select based on assembly process requirements and packaging needs.

Q: Can Sullins NPPN252FFKS-RC or NPPN252FFKP-RC replace the Molex 0791098674?

Q: What are the key differences in operating temperature ranges?

A: The Molex 0791098674 and Amphenol ICC 55510-150TRLF operate across -55°C ~ 125°C. The 3M 150250 series and Sullins parts operate across -55°C ~ 105°C and -40°C ~ 105°C respectively. Select based on application temperature requirements.

Q: Does the Amphenol ICC 55510-150TRLF provide higher current capacity?

A: Yes. The Amphenol ICC part is rated for 2A per contact compared to 1A for the Molex 0791098674. This higher current rating is suitable for applications requiring increased power delivery per contact.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0791098674 and Sullins parts are ROHS3 compliant. The 3M and Amphenol ICC parts are RoHS compliant. All parts are REACH unaffected.

Q: What packaging options are available?

A: Molex 0791098674 is supplied in Tape & Reel (TR). The 3M 150250-2000-RB is Bulk; the 150250-2020-RB-WF is Cut Tape (CT). The Amphenol ICC 55510-150TRLF is Cut Tape (CT). Sullins parts are supplied in Tube packaging. Select based on assembly equipment compatibility and inventory management requirements.
