Substitute Part Grouping Explanation

Substitution for the Molex 0791070010 is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 22 positions at 0.079" (2.00mm) mating pitch
Row Configuration: 2 rows with 0.079" (2.00mm) row spacing
Mounting & Termination: Through-hole solder termination with push-pull fastening
Contact Finish: Gold-plated mating surface
Operating Range: -55°C to 125°C temperature capability

The substitute parts listed below meet these core electrical and mechanical requirements. Both Amphenol ICC (FCI) Minitek® 2.00mm connectors (63453-022LF and 63453-122LF) maintain identical position count, pitch, row configuration, mounting type, and fastening mechanism. These parts are active products with enhanced electrical ratings and improved compliance status compared to the obsolete Molex original.

Engineering Selection Recommendations

The Molex 0791070010 is obsolete and no longer manufactured. Both Amphenol ICC Minitek® 2.00mm alternatives (63453-022LF and 63453-122LF) are active products that maintain full mechanical and electrical compatibility with the original connector.

Key advantages of substitute parts:

Both substitutes are RoHS compliant, whereas the original is non-compliant
Current rating increased from 1A to 2A
Voltage rating increased from 125V to 200V
Active product status ensures ongoing availability and supply chain support
Identical connector geometry, pitch, row configuration, and fastening mechanism
Operating temperature range maintained at -55°C to 125°C

The primary difference between the two Amphenol ICC substitutes is the gold plating thickness on mating contacts: 63453-022LF provides 8.00µin (0.203µm) while 63453-122LF provides 30.0µin (0.76µm). Selection between these two should be based on specific contact durability and mating cycle requirements for your application.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 63453-022LF or 63453-122LF directly replace the Molex 0791070010?

A: Yes. Both parts are mechanically and electrically compatible. They share identical position count (22), pitch (0.079" / 2.00mm), row configuration (2 rows at 0.079" spacing), mounting type (through-hole), termination method (solder), and fastening mechanism (push-pull). The substitute parts exceed the original specifications in current rating (2A vs. 1A) and voltage rating (200V vs. 125V).

Q: What is the difference between Amphenol ICC 63453-022LF and 63453-122LF?

A: The primary difference is the gold plating thickness on mating contacts. The 63453-022LF has 8.00µin (0.203µm) gold plating, while the 63453-122LF has 30.0µin (0.76µm) gold plating. Both maintain the same electrical and mechanical specifications. The thicker plating on the 63453-122LF may provide enhanced durability for high-cycle mating applications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both Amphenol ICC 63453-022LF and 63453-122LF are RoHS compliant. The original Molex 0791070010 is RoHS non-compliant.

Q: Will the substitute connectors fit the same PCB footprint?

A: The substitute parts maintain the same pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), and through-hole termination as the original. Insulation height differs slightly (0.177" vs. 0.175"), but this does not affect PCB footprint compatibility. Verify board layout clearances for the minor dimensional variations listed in the parameter comparison table.

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

A: Both Amphenol ICC substitutes are supplied in tube packaging, whereas the original Molex part packaging is not specified in available documentation.

Q: Are the operating temperature ranges identical?

A: Yes. All three connectors operate across -55°C to 125°C, ensuring thermal compatibility across the full operating range.
