Substitute Part Grouping Explanation

Substitution eligibility for the 960242-6303-AR is determined by the following critical parameters:

Connector Type & Style: Receptacle, board-to-board configuration
Position Count & Pitch: 42 positions at 0.100" (2.54mm) mating pitch
Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
Mounting & Termination: Through-hole solder termination with push-pull fastening
Electrical Performance: Minimum 2A current rating and 500VDC voltage rating
Environmental Compliance: UL94 V-0 flammability rating, operating temperature range compatibility

Three substitute parts meet these core substitution criteria with variations in contact finish, insulation material, and electrical ratings.

Engineering Selection Recommendations

0015445142 (Molex C-Grid 71850): This part is the primary recommended substitute. It maintains full mechanical and electrical compatibility with identical pitch, row spacing, and position count. The Molex part offers enhanced current rating (2.5A vs. 2A) and extended operating temperature range (-40°C ~ 125°C). Both parts carry UL94 V-0 certification and unlimited moisture sensitivity level (MSL 1). The Molex part is ROHS3 compliant and REACH unaffected, providing superior regulatory compliance for modern applications.

2-146762-2 (TE Connectivity AMPMODU Mod IV): This substitute provides mechanical compatibility with identical connector geometry and pitch specifications. The TE part features tin-lead contact finish instead of gold and supports the same 2A current rating. Operating temperature range extends to -65°C ~ 125°C, suitable for extended environmental conditions. ROHS3 compliance is confirmed. Voltage rating is not specified for this part.

PPPC212LFBN-RC (Sullins Connector Solutions): This part differs in connector type (header vs. receptacle) and is suitable only for applications where the mating interface can accommodate a header configuration. It provides higher current rating (3A) and gold contact finish. Operating temperature range is -40°C ~ 105°C with UL94 V-0 certification and ROHS3 compliance. Voltage rating is limited to 250V.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0015445142 directly replace the 3M 960242-6303-AR?

A: Yes. Both parts share identical mechanical specifications: 42 positions, 0.100" (2.54mm) pitch, 2-row configuration, through-hole solder termination, and push-pull fastening. The Molex part meets or exceeds the electrical requirements of the original part.

Q: What is the key difference between the TE Connectivity 2-146762-2 and the Molex substitute?

A: The TE part uses tin-lead contact finish instead of gold and does not specify a voltage rating. Both maintain identical mechanical compatibility and 2A current rating. The TE part supports a wider operating temperature range (-65°C ~ 125°C).

Q: Why is the Sullins PPPC212LFBN-RC listed as a substitute if it is a header, not a receptacle?

A: The Sullins part is a header connector with identical pitch, position count, and row spacing. It functions as a substitute only in applications where the mating interface is designed for header-type connectors. Mechanical and electrical parameters are otherwise compatible.

Q: Are all substitute parts RoHS compliant?

A: The Molex 0015445142 and TE Connectivity 2-146762-2 are ROHS3 compliant. The Sullins PPPC212LFBN-RC is also ROHS3 compliant. The original 3M part status regarding RoHS compliance is not specified.

Q: What packaging formats are available for these substitutes?

A: The Molex 0015445142 is supplied in tray packaging. The TE Connectivity 2-146762-2 is supplied in tube packaging. The Sullins PPPC212LFBN-RC is supplied in tray packaging.

Q: Does the operating temperature range affect substitution decisions?

A: The original 3M part operates from -25°C ~ 105°C. All three substitutes support this range or exceed it. The Molex and TE parts extend to -40°C and -65°C respectively at the lower end, and to 125°C at the upper end. The Sullins part matches the upper limit at 105°C. Selection depends on specific application temperature requirements.
