Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0878313821 is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (38)
• 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)
• Minimum current rating (2A or greater)
• Minimum voltage rating (125V or greater)
• Material flammability rating (UL94 V-0)

The Amphenol ICC (FCI) part 10075025-G01-38ULF meets all critical substitution criteria. Both connectors share identical mating pitch, row configuration, position count, and shrouding design. Both are rated for 2A current and UL94 V-0 flammability. The Amphenol part exceeds the voltage requirement at 200V and maintains through-hole solder termination compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0878313821 and Amphenol ICC 10075025-G01-38ULF are active products with current manufacturing status. Selection between these parts is based on availability, supply chain requirements, and packaging format.

The Molex part is supplied in standard packaging with 945 units in current inventory. The Amphenol ICC equivalent is supplied in tube packaging with 991 units in current inventory.

Both parts maintain ROHS3/RoHS compliance and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Both are rated UL94 V-0 for flammability. The Amphenol part provides higher voltage margin at 200V versus the Molex specification of 125V, while maintaining identical current rating and pitch specifications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10075025-G01-38ULF directly replace the Molex 0878313821 in existing designs?

A: Yes. Both connectors share identical mating pitch (2.00mm), position count (38), row configuration (2 rows), shrouding design (4-wall), and through-hole solder termination. Mechanical and electrical compatibility is maintained.

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

A: The primary differences are manufacturer series designation (Milli-Grid 87831 versus Minitek® 2.00mm), contact finish specification (standard gold versus gold with GXT™ enhancement), insulation material composition, and voltage rating (125V versus 200V). Current rating, pitch, and position count are identical.

Q: Are there packaging considerations when switching between these parts?

A: The Molex part uses standard packaging while the Amphenol ICC part is supplied in tube packaging. Verify packaging compatibility with assembly and procurement workflows.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and rated UL94 V-0 for flammability. Both carry MSL 1 (Unlimited) moisture sensitivity ratings. The Molex part is specifically ROHS3 compliant while the Amphenol part is RoHS compliant.

Q: What is the operating temperature range for these connectors?

A: The Molex 0878313821 operates from -55°C to 105°C. Operating temperature specification for the Amphenol ICC part was not provided in the technical data.
