Equivalent & Substitute Parts for Molex 0791077134

Part Overview

The Molex 0791077134 is a 20-position receptacle connector in the Milli-Grid 79107 series, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch spacing. This through-hole mounted connector features gold-plated mating contacts, tin-plated posts, and operates across -55°C to 125°C. The part is active and in production with 793 units currently in stock.

Equivalent and substitute parts are identified when design requirements change, inventory constraints occur, or performance specifications demand higher ratings or alternative material properties. The substitute connectors listed maintain core mechanical and electrical compatibility while offering variations in current capacity, voltage rating, insulation material, and flammability certification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following core parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 20
• Pitch - Mating: 0.079" (2.00mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Insulation Color: Black

Variable Parameters (Allowed to Differ):

• Current Rating (Amps)
• Voltage Rating
• Operating Temperature Range
• Insulation Material
• Material Flammability Rating
• Contact Finish Thickness values
• Insulation Height (within mechanical tolerance)
• Contact Length - Post (within mechanical tolerance)

All four substitute parts meet the mandatory matching criteria and are therefore electrically and mechanically compatible with the Molex 0791077134 in applications where the variable parameters are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Amphenol ICC 63453-120LF (Minitek® 2.00mm Series)

This substitute offers increased current capacity (2A vs. 1A) and voltage rating (200V vs. 125V) with UL94 V-0 flammability certification. The insulation material is PCT with glass fill. All parts are active and in production. This option is suitable for applications requiring higher electrical performance within the same mechanical footprint.

Harwin M22-7141042 (M22 Series)

This substitute provides the highest voltage rating (500VAC) and current capacity (2A) with UL94 V-0 flammability certification. The insulation material is Liquid Crystal Polymer (LCP). Operating temperature range is -40°C to 105°C, which is narrower than the original part. All parts are active and in production. This option is suitable for industrial and telecommunications applications requiring enhanced voltage performance.

Samtec MMS-110-01-F-DV and MMS-110-01-S-DV (MMS Series)

Both Samtec options provide the highest current rating (3.9A per contact) with Liquid Crystal Polymer (LCP) insulation. Operating temperature range matches the original (-55°C to 125°C). Voltage rating is not specified for these parts. Moisture Sensitivity Level is Not Applicable. All parts are active and in production. These options are suitable for applications requiring maximum current capacity within the same thermal operating range.

All substitute parts maintain ROHS3 compliance or equivalent RoHS compliance and are classified under the same HTSUS code (8536.69.4040).

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0791077134 with any of these parts without design changes?

A: Yes, all four substitute parts are mechanically and electrically compatible. They share identical pitch spacing (0.079" / 2.00mm), number of positions (20), row configuration (2 rows), mounting type (through hole), and contact finish specifications. No PCB layout or mating connector changes are required.

Q: What is the primary difference between these substitutes?

A: The primary differences are current rating, voltage rating, insulation material, and flammability certification. The Molex original is rated 1A at 125V. The Amphenol and Harwin options increase to 2A with higher voltage ratings. The Samtec options provide the highest current capacity (3.9A per contact) but do not specify voltage rating.

Q: Which substitute should I choose if my application requires higher current capacity?

A: The Samtec MMS-110-01-F-DV and MMS-110-01-S-DV both provide 3.9A per contact, the highest available among the listed substitutes. Both maintain the -55°C to 125°C operating temperature range of the original part.

Q: Are all these parts RoHS compliant?

A: Yes. The Molex original, Harwin, and both Samtec parts are ROHS3 compliant. The Amphenol part is RoHS compliant. All meet environmental compliance requirements.

Q: What is the difference between the two Samtec options (MMS-110-01-F-DV and MMS-110-01-S-DV)?

A: Both Samtec parts are identical in electrical and mechanical specifications. The difference is in the contact finish thickness on the mating side: MMS-110-01-F-DV has 3.00µin (0.076µm) while MMS-110-01-S-DV has 30.0µin (0.76µm). Both are functionally equivalent for standard applications.

Q: Does the Harwin M22-7141042 have any temperature limitations compared to the original?

A: Yes. The Harwin part operates from -40°C to 105°C, which is narrower than the Molex original (-55°C to 125°C). If your application requires the full -55°C to 125°C range, use the Molex original, Amphenol, or Samtec options instead.

Q: What does the flammability rating UL94 V-0 mean?

A: UL94 V-0 indicates the material meets UL94 vertical flame test requirements with no flaming drips and burn time less than 10 seconds. The Amphenol and Harwin substitutes carry this certification. The Molex original and Samtec options do not specify a flammability rating.

Q: Are there any REACH compliance differences?

A: The Molex original and both Samtec parts are REACH Unaffected. The Amphenol part is REACH Affected. The Harwin part status is not specified in the provided data. Verify REACH compliance requirements for your specific application and region.
