Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by matching the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (26)
Number of rows (2)
Pitch - mating (0.079" / 2.00mm)
Row spacing - mating (0.079" / 2.00mm)
Mounting type (Through Hole)
Shrouding configuration (Shrouded - 4 Wall)
Termination method (Solder)
Contact shape (Square)
Material flammability rating (UL94 V-0)
Moisture sensitivity level (MSL 1)

The identified substitute parts meet all critical parameters. Variations in contact length, insulation height, fastening type, contact finish specifications, and voltage rating do not preclude substitution when the core mating and mounting characteristics are identical.

Engineering Selection Recommendations

Both Amphenol ICC substitute parts are active products with full RoHS compliance and MSL 1 moisture sensitivity rating, matching the environmental and regulatory requirements of the Molex 0878312629.

Amphenol ICC 10075025-G01-26ULF is supplied in tube packaging and maintains electrical specifications equivalent to the original part. This option provides direct packaging compatibility for applications requiring tubed components.

Amphenol ICC 98414-G06-26LF is supplied in bulk packaging with significantly higher inventory availability (2392 units). This part is suitable for high-volume production environments where bulk packaging is acceptable. The REACH Affected status indicates compliance with REACH regulations with substance notification requirements.

Both substitute parts feature enhanced voltage rating (200V versus 125V) and GXT™ gold contact finish, providing improved electrical performance margins. Contact length and insulation height variations are within acceptable tolerances for standard through-hole board mounting applications.

Frequently Asked Questions (FAQ)

Q: Can Amphenol ICC 10075025-G01-26ULF directly replace Molex 0878312629 in existing designs?

A: Yes. Both parts share identical mating pitch (2.00mm), row spacing (2.00mm), position count (26), shrouding configuration (4-wall), and mounting type (through-hole). The contact length difference (0.157" versus 0.141") and insulation height variation (0.220" versus 0.252") do not affect board-level compatibility for standard PCB mounting applications.

Q: What is the difference between the two Amphenol ICC substitute options?

A: Amphenol ICC 10075025-G01-26ULF is packaged in tubes with 848 units in stock, while Amphenol ICC 98414-G06-26LF is supplied in bulk with 2392 units available. The tube option maintains packaging consistency with the original Molex part. The bulk option provides higher inventory availability and lower per-unit cost for volume orders.

Q: Are there voltage rating differences between the original and substitute parts?

A: The Molex 0878312629 is rated at 125V, while both Amphenol ICC substitutes are rated at 200V. The higher voltage rating of the substitute parts provides additional electrical performance margin and does not restrict their use in 125V applications.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All three parts are UL94 V-0 rated, MSL 1 classified, and RoHS compliant. Both Amphenol ICC parts maintain full regulatory compliance with the original Molex specification.

Q: What is the significance of the GXT™ contact finish on the substitute parts?

A: GXT™ is an enhanced gold plating specification that provides improved corrosion resistance and contact reliability compared to standard gold plating. This upgrade does not affect compatibility but offers enhanced performance characteristics.
