Engineering Selection Recommendations

Both the Molex 0791077018 and Samtec MMS-119-01-S-DV maintain Active product status with full ROHS3 compliance and identical export classification (EAR99). The connectors share identical electrical and mechanical specifications for mating pitch, row configuration, mounting method, and operating temperature range. Selection between these parts should be based on supply chain availability, lead time requirements, or specific application constraints. Both parts are suitable for automotive, general purpose, and telecommunications applications requiring 38-position rectangular connectors with 0.079" pitch and through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Can the Samtec MMS-119-01-S-DV be used as a direct replacement for the Molex 0791077018?

A: Yes. Both connectors share identical mating pitch (0.079"), position count (38), row configuration (2 rows), mounting type (through-hole), termination method (solder), and operating temperature range (-55°C ~ 125°C). The connectors are mechanically and electrically compatible for applications requiring these specifications.

Q: What are the key differences between these two connectors?

A: The primary differences are in contact finish thickness on mating surfaces (Molex: 15.0µin vs. Samtec: 30.0µin), contact length on the post (Molex: 0.118" vs. Samtec: 0.115"), insulation material (Molex: Thermoplastic Glass Filled vs. Samtec: Liquid Crystal Polymer), and current rating per contact (Molex: 1A vs. Samtec: 3.9A per contact). These differences do not affect substitution eligibility for standard applications.

Q: Are both connectors RoHS compliant?

A: Yes. Both the Molex 0791077018 and Samtec MMS-119-01-S-DV are ROHS3 compliant and carry identical HTSUS classification (8536.69.4040).

Q: What packaging format is used for these connectors?

A: Both connectors are supplied in tube packaging, suitable for automated assembly and manual handling.

Q: Do these connectors support the same voltage and current specifications?

A: Both connectors operate within the same temperature range (-55°C ~ 125°C) and support push-pull fastening. The Samtec part specifies a higher current rating per contact (3.9A vs. 1A), making it suitable for applications requiring higher current capacity while maintaining compatibility with standard 1A applications.
