Molex 0791077061 Equivalent & Substitute Parts

Part Overview

The Molex 0791077061 is a 24-position receptacle connector from the Milli-Grid 79107 series, designed for board-to-board or cable applications. This through-hole mounted connector features 0.079" (2.00mm) pitch spacing, gold-plated mating contacts, and solder termination with push-pull fastening. The part is active in production with 941 units currently in stock. Equivalent parts are necessary when primary inventory is depleted, when alternative manufacturers offer superior performance characteristics, or when design requirements necessitate enhanced electrical ratings or operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0791077061 is determined by strict alignment with the following core parameters: 24-position configuration, 0.079" (2.00mm) mating pitch, 2-row layout with 0.079" row spacing, receptacle connector type with female socket contacts, through-hole mounting, solder termination, push-pull fastening, gold-plated mating contacts, square contact geometry, and phosphor bronze contact material. All substitute parts listed maintain these mandatory specifications. Variations in secondary parameters such as insulation height, contact post length, current rating, voltage rating, operating temperature range, and insulation material are permitted when the primary mechanical and electrical interface requirements remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full mechanical and electrical interface compatibility with the Molex 0791077061 through identical pitch, row configuration, contact geometry, and termination specifications. All parts are ROHS3 compliant and active in production status.

The Harwin M22-7141242 provides enhanced current capacity (2A versus 1A) and significantly higher voltage rating (500VAC versus 125V), making it suitable for higher-power applications. However, its operating temperature range is restricted to -40°C ~ 105°C compared to the Molex specification of -55°C ~ 125°C, and insulation height is marginally reduced to 0.173" (4.40mm). Contact post length is shorter at 0.094" (2.40mm).

The Samtec MMS-112-01-F-DV and MMS-112-01-S-DV both maintain the full operating temperature range of -55°C ~ 125°C and identical insulation height of 0.175" (4.45mm) to the Molex part. Both offer substantially higher current capacity at 3.9A per contact. Contact post length is 0.115" (2.92mm), slightly shorter than the Molex specification. Moisture sensitivity level is listed as not applicable for both Samtec variants. The primary distinction between the two Samtec options is the contact finish thickness on mating surfaces: MMS-112-01-F-DV specifies 3.00µin (0.076µm) while MMS-112-01-S-DV specifies 30.0µin (0.76µm), matching the Molex gold plating thickness.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M22-7141242 be used in applications requiring the full -55°C ~ 125°C operating temperature range?

A: No. The Harwin part is rated only to -40°C ~ 105°C. Applications requiring operation below -40°C or above 105°C must use the Molex 0791077061 or Samtec alternatives.

Q: What is the difference between the two Samtec substitute parts?

A: MMS-112-01-F-DV and MMS-112-01-S-DV are mechanically and electrically identical. The only specified difference is the gold plating thickness on mating contacts: MMS-112-01-F-DV at 3.00µin (0.076µm) versus MMS-112-01-S-DV at 30.0µin (0.76µm). The MMS-112-01-S-DV matches the Molex gold plating thickness specification.

Q: Are all substitute parts through-hole mounted with solder termination?

A: Yes. All substitute parts use through-hole mounting with solder termination and push-pull fastening, maintaining full compatibility with PCB layouts designed for the Molex 0791077061.

Q: Do the substitute parts maintain the same 24-position, 2-row configuration with 0.079" pitch?

A: Yes. All substitute parts maintain identical 24-position configuration, 2-row layout, and 0.079" (2.00mm) mating pitch and row spacing.

Q: Which substitute part offers the highest current capacity?

A: Both Samtec parts (MMS-112-01-F-DV and MMS-112-01-S-DV) offer 3.9A per contact, compared to 1A for the Molex original and 2A for the Harwin alternative.

Q: Are all parts RoHS3 compliant?

A: Yes. The Molex 0791077061 and all three substitute parts are ROHS3 compliant.
