Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0740621111 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins; VHDM, Guide Right)
• Position count and matrix configuration (80 positions; 8×10 rows/columns)
• Pitch specification (0.079" / 2.00mm)
• Electrical ratings (3A current, 120V voltage)
• Mounting and termination method (Through Hole, Press-Fit)
• Operating temperature range (-55°C to 105°C)
• Contact finish specification (Gold plating)
• Shielding requirement

The substitute part 0740621001 maintains identical electrical, mechanical, and dimensional specifications while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740621001 is the direct functional equivalent of the obsolete 0740621111. Both parts are identical in electrical performance, mechanical dimensions, and connector specifications. The primary distinction is product lifecycle status and regulatory compliance.

The 0740621001 is recommended for all new designs and production applications due to its active product status and ROHS3 compliance. For legacy system maintenance where the original 0740621111 is specified, the 0740621001 provides drop-in compatibility without design modification.

The transition from RoHS non-compliant to ROHS3 compliant status reflects current regulatory requirements and does not affect electrical or mechanical performance in the application.

Frequently Asked Questions (FAQ)

Q: Can the 0740621001 be used as a direct replacement for the 0740621111?

A: Yes. Both parts share identical connector type, position count, pitch, electrical ratings, and mounting specifications. The 0740621001 is functionally equivalent and mechanically compatible.

Q: What is the difference between these two part numbers?

A: The 0740621111 is obsolete and RoHS non-compliant. The 0740621001 is an active product with ROHS3 compliance. All electrical and mechanical parameters are identical.

Q: Does the packaging difference affect compatibility?

A: No. The 0740621111 uses standard packaging while the 0740621001 is supplied in tube packaging. This affects only handling and storage logistics, not component performance or PCB integration.

Q: Are there any design considerations when switching from 0740621111 to 0740621001?

A: No design changes are required. The parts are pin-for-pin and footprint-compatible. PCB layouts, mating connectors, and electrical specifications remain unchanged.

Q: What certifications apply to the substitute part?

A: The 0740621001 carries UL94 V-0 flammability rating and ROHS3 compliance. Both parts maintain the same voltage (120V) and current (3A) ratings with identical operating temperature range (-55°C to 105°C).
