Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0878331221 is determined by strict alignment of the following critical parameters:

Connector Type: Header
Contact Type: Male Pin
Pitch - Mating: 0.079" (2.00mm)
Number of Positions: 12
Number of Rows: 2
Row Spacing - Mating: 0.079" (2.00mm)
Mounting Type: Through Hole, Right Angle
Shrouding: Shrouded - 4 Wall
Termination: Solder
Contact Finish - Mating: Gold
Material Flammability Rating: UL94 V-0

Both identified substitute parts meet these core requirements. Variations in fastening type, contact length specifications, insulation material composition, and packaging format do not preclude functional substitution when these critical parameters align.

Engineering Selection Recommendations

All three parts maintain active product status and comply with UL94 V-0 flammability requirements and RoHS standards. The Molex 0878331221 is ROHS3 compliant, while both Amphenol ICC substitutes are RoHS compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity classification.

The Amphenol ICC 10072354-G01-12ULF and 98464-G61-12LF are functionally equivalent for applications requiring the specified 2.00mm pitch, 12-position, 2-row header configuration with right-angle through-hole mounting and 4-wall shrouding. Selection between substitute parts should be based on fastening mechanism requirements (Detent Lock versus Latch Holder), contact post length specifications, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10072354-G01-12ULF directly replace the Molex 0878331221?

A: Yes. Both parts share identical pitch (2.00mm), position count (12), row configuration (2), mounting type (through-hole right-angle), shrouding (4-wall), and contact finish specifications (gold mating surface). Differences in fastening type and contact length do not prevent functional substitution when mechanical envelope constraints are satisfied.

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

A: The 10072354-G01-12ULF uses Detent Lock fastening with 0.079" (2.00mm) contact post length, while the 98464-G61-12LF uses Latch Holder fastening with 0.098" (2.50mm) contact post length. The 10072354-G01-12ULF is packaged in Tube format; the 98464-G61-12LF is packaged in Bulk format.

Q: Are there voltage or current rating differences between these parts?

A: The Molex 0878331221 does not specify voltage or current ratings in the provided data. The Amphenol ICC 10072354-G01-12ULF is rated for 3A at 200V (AC/DC), and the 98464-G61-12LF is rated for 2A at 200V (AC/DC). Application-specific electrical requirements must be evaluated independently.

Q: Do insulation material differences affect substitution?

A: The Molex part uses glass-filled polyamide insulation; both Amphenol ICC substitutes use thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements. Material selection should be confirmed against specific application thermal and chemical exposure requirements.

Q: What packaging options are available?

A: The Molex 0878331221 and Amphenol ICC 10072354-G01-12ULF are supplied in Tube packaging. The Amphenol ICC 98464-G61-12LF is supplied in Bulk packaging. Packaging format selection depends on assembly process requirements and inventory management practices.
