Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 25640401RP2 is determined by strict alignment of the following critical parameters:

• Connector type (Receptacle) and contact type (Female Socket)
• Position count (4 positions) and row configuration (2 rows)
• Pitch spacing (0.079" / 2.00mm) for both mating and row spacing
• Mounting method (Through Hole) and termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact material (Phosphor Bronze) and mating contact finish (Gold)
• Current rating (1A minimum)
• Insulation material composition (Thermoplastic, Glass Filled)
• Regulatory compliance (ROHS3 Compliant)

The substitute part 0791077001 (Molex Milli-Grid 79107 series) meets all these critical parameters, enabling direct functional replacement in applications requiring 4-position rectangular connectors with 2.00mm pitch spacing and push-pull fastening.

Parameter Comparison

Engineering Selection Recommendations

The 0791077001 (Molex Milli-Grid 79107) serves as a direct functional equivalent to the obsolete 25640401RP2. Both components share identical mechanical and electrical specifications across all critical parameters, including pitch spacing, contact configuration, current rating, and material composition. The Molex substitute maintains ROHS3 compliance and is currently in active production status with established supply chain availability. Selection of the 0791077001 is supported by full parameter alignment and regulatory compliance parity with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 0791077001 be used as a direct replacement for the 25640401RP2?

A: Yes. Both connectors share identical specifications for position count, pitch spacing (0.079" / 2.00mm), row configuration, mounting type, termination method, fastening mechanism, contact material, and current rating. PCB footprints and mating interface dimensions are compatible.

Q: What are the key compatibility criteria for this connector category?

A: Substitution requires matching connector type (receptacle), contact type (female socket), position count (4), pitch spacing (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), mounting method (through hole), termination type (solder), fastening type (push-pull), contact material (phosphor bronze), and mating contact finish (gold).

Q: Does the Molex 0791077001 have different operating temperature specifications?

A: The Molex 0791077001 operates across -55°C to 125°C, which exceeds the NorComp 25640401RP2 range of -40°C to 105°C. This provides extended thermal capability for applications requiring broader temperature performance.

Q: Are both components RoHS compliant?

A: Yes. Both the 25640401RP2 and 0791077001 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the packaging format for the substitute part?

A: The Molex 0791077001 is supplied in tube packaging, suitable for automated assembly and manual component handling.
