25642201RP2 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 25642201RP2 is a 22-position receptacle connector manufactured by NorComp Inc., designed for through-hole PCB mounting with 0.079" (2.00mm) pitch spacing. This connector features gold-plated mating contacts, tin-plated posts, and push-pull fastening, rated for 1A current operation across -40°C to 105°C. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 25642201RP2 is determined by strict equivalence across the following electrical and mechanical parameters:

• 22-position configuration with 2-row layout
• 0.079" (2.00mm) pitch spacing (both mating and row spacing)
• Through-hole solder termination
• Push-pull fastening mechanism
• Female socket contact type
• Gold-plated mating contacts
• Phosphor bronze contact material
• 1A current rating capability
• Thermoplastic, glass-filled insulation

The substitute part 0791077010 (Molex Milli-Grid 79107 series) meets all these core electrical and mechanical requirements, enabling direct functional replacement in applications where the 25642201RP2 is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The 0791077010 (Molex Milli-Grid 79107) is the direct functional equivalent for the obsolete 25642201RP2. Both connectors are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Molex substitute maintains identical electrical and mechanical specifications across all critical parameters: 22-position configuration, 0.079" pitch, through-hole solder termination, and 1A current rating.

The primary distinction is product status: the 25642201RP2 is obsolete with limited inventory availability, while the 0791077010 is an active product with established supply chain support. The Molex connector operates across an extended temperature range (-55°C ~ 125°C) compared to the NorComp original (-40°C ~ 105°C), providing additional thermal margin for demanding applications.

For new designs or component replenishment, the 0791077010 is the appropriate selection. For legacy system maintenance requiring exact form-factor compatibility, the 25642201RP2 remains available in limited quantities.

Frequently Asked Questions (FAQ)

Q: Can the 0791077010 directly replace the 25642201RP2 in existing PCB designs?

A: Yes. Both connectors share identical pitch spacing (0.079"), position count (22), row configuration (2 rows), mounting type (through-hole), and contact specifications. PCB footprints are compatible without modification.

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

A: The primary differences are manufacturer (NorComp vs. Molex), product status (obsolete vs. active), and operating temperature range. The Molex 0791077010 operates from -55°C to 125°C, while the NorComp 25642201RP2 operates from -40°C to 105°C. Both meet ROHS3 compliance and carry identical electrical ratings.

Q: Are there packaging differences between the two parts?

A: The 25642201RP2 packaging is not specified in available documentation. The 0791077010 is supplied in tube packaging. Verify packaging requirements for your procurement process.

Q: Do both connectors support the same mating interface?

A: Yes. Both use push-pull fastening with identical contact geometry, allowing them to mate with the same plug connectors and cable assemblies.

Q: Which connector should be specified for new designs?

A: The 0791077010 (Molex Milli-Grid 79107) should be specified for new designs due to its active product status, established supply chain availability, and extended operating temperature range.
