Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740601004 is determined by strict equivalence across the following critical parameters:

Connector style: VHDM
Number of positions: 80
Position arrangement: 8 rows × 10 columns
Pitch: 0.079" (2.00mm)
Connector type: Header with male pins
Mounting method: Through-hole, press-fit termination
Shielded construction
Contact finish: Gold plating at 30.0µin (0.76µm) thickness
Color: Black
Material flammability: UL94 V-0

Engineering Selection Recommendations

The Molex 0761349001 is the direct substitute for the obsolete 0740601004. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector geometry, pitch, contact configuration, and operating ratings.

The 0761349001 offers the advantage of active product status, ensuring ongoing availability and manufacturing support. Additionally, the 0761349001 achieves ROHS3 compliance, whereas the 0740601004 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 0761349001 is the appropriate selection.

Both parts carry identical certifications for material flammability (UL94 V-0) and moisture sensitivity (MSL 1). The substitute part is supplied in tube packaging, which may differ from the original part's packaging configuration.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761349001 be used as a direct replacement for the 0740601004 in existing designs?

A: Yes. The 0761349001 is electrically and mechanically equivalent to the 0740601004 across all specified parameters. PCB footprints, mounting hole patterns, and connector pin assignments are identical. No design modifications are required.

Q: What is the primary difference between these two parts?

A: The 0740601004 is obsolete, while the 0761349001 is an active product. The 0761349001 also achieves ROHS3 compliance, whereas the 0740601004 is RoHS non-compliant. All other electrical and mechanical characteristics are identical.

Q: Are there any compatibility concerns with the packaging difference?

A: The 0740601004 packaging is not specified in available documentation. The 0761349001 is supplied in tube packaging. Packaging differences do not affect component functionality or PCB integration. Verify packaging requirements for your specific procurement and assembly processes.

Q: What are the critical parameters that define substitution eligibility for this connector?

A: Substitution is determined by equivalence in connector style (VHDM), position count (80), row/column configuration (8×10), pitch (2.00mm), mounting method (through-hole press-fit), shielding, contact finish specifications, color, flammability rating, and operating temperature range. All these parameters must match for functional equivalence.

Q: Is the 0761349001 suitable for applications with RoHS compliance requirements?

A: Yes. The 0761349001 is ROHS3 compliant and is the appropriate choice for designs subject to RoHS regulatory requirements. The original 0740601004 is RoHS non-compliant.
