Engineering Selection Recommendations

For RoHS Compliance Requirements: Select from Amphenol ICC 63453-128LF, Hirose Electric A3C-28DA-2DSA(71), A3C-28DA-2DSC(71), Harwin M22-7141442, or Samtec MMS-114-01-H-DV and MMS-114-01-L-DV-07. These parts carry RoHS or ROHS3 compliance certifications.

For Extended Temperature Range (-55°C to 125°C): Molex 0791070013, Amphenol ICC 63453-128LF, Mill-Max 833-13-028-10-002000, and all Samtec MMS series variants maintain the full -55°C to 125°C operating range. Hirose A3 series and Harwin M22 series operate within narrower ranges.

For Higher Current Capacity: Samtec MMS series (3.9A per contact), Mill-Max 833-13-028-10-002000 (3A), and Amphenol ICC 63453-128LF (2A) exceed the original 1A rating.

For Higher Voltage Rating: Harwin M22-7141442 (500VAC) and Amphenol ICC 63453-128LF (200V) provide enhanced voltage performance over the original 125V specification.

For Active Production Support: All substitute parts listed carry Active product status, ensuring ongoing availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different current rating? A: Yes. Substitute parts with equal or higher current ratings are functionally compatible. The Molex 0791070013 specifies 1A; substitutes rated at 2A, 3A, or 3.9A per contact will operate safely in applications requiring 1A or less.

Q: Are the Samtec MMS-114-01-L-DV-04 and MMS-114-01-L-DV-07 compatible if only 27 positions are loaded instead of 28? A: These parts are mechanically and electrically compatible with the 28-position Molex 0791070013. The "27 Loaded" designation indicates the connector body accommodates 28 positions but only 27 are populated with contacts. This does not affect compatibility with fully populated 28-position mating connectors.

Q: What is the difference between Hirose A3C-28DA-2DSA(71) and A3C-28DA-2DSC(71)? A: Both are 28-position receptacles with identical electrical specifications. The primary difference is packaging: A3C-28DA-2DSA(71) is supplied in Tray packaging, while A3C-28DA-2DSC(71) is supplied in Tube packaging. Electrical and mechanical performance are equivalent.

Q: Does the contact finish material affect compatibility? A: No. The Molex 0791070013 features Tin-Lead post finish; substitutes with Tin or Gold post finishes are fully compatible. Post finish does not affect mating performance with standard connector plugs.

Q: Which substitute offers the best compliance profile? A: Amphenol ICC 63453-128LF, Hirose A3C-28DA-2DSA(71), A3C-28DA-2DSC(71), Harwin M22-7141442, and Samtec MMS-114-01-L-DV-07 all carry RoHS or ROHS3 compliance certifications, meeting modern regulatory requirements.

Q: Can I substitute the Molex 0791070013 in automotive applications? A: Yes. The original part lists automotive applications. Amphenol ICC 63453-128LF, Hirose A3 series, Harwin M22-7141442, and Samtec MMS series are all suitable for general purpose and industrial applications. Verify specific automotive qualification requirements with your application engineer.

Q: What is the impact of operating temperature range differences? A: The Molex 0791070013 operates -55°C to 125°C. Hirose A3 series and Harwin M22 operate within narrower ranges (-55°C to 85°C and -40°C to 105°C respectively). Select substitutes based on your application's actual operating temperature requirements.
