Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740611073 is determined by strict equivalence across the following critical parameters:

• Connector type and style: Header, Male Pins with VHDM, Guide Left configuration
• Position count and arrangement: 80 positions in 8 rows × 10 columns
• Pitch specification: 0.079" (2.00mm)
• Mounting and termination: Through-hole with press-fit termination
• Electrical ratings: 3A current rating and 120V voltage rating
• Physical characteristics: Shielded design with gold-plated contacts at 30.0µin thickness
• Material compliance: UL94 V-0 flammability rating

The substitute part 0740611004 meets all these criteria while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct functional equivalent of the 0740611073. Both parts share identical electrical, mechanical, and physical specifications across all critical parameters. The primary distinctions are product lifecycle status and regulatory compliance.

The 0740611073 is classified as obsolete and does not meet RoHS3 compliance requirements. The 0740611004 maintains active product status and achieves ROHS3 compliance while preserving all functional characteristics. For new designs and ongoing system support, the 0740611004 is the appropriate selection. The substitute part is available in tube packaging, whereas the original part was supplied in bulk format.

Frequently Asked Questions (FAQ)

Q: Are the 0740611073 and 0740611004 mechanically interchangeable?

A: Yes. Both parts feature identical connector geometry, pitch spacing (0.079" / 2.00mm), position count (80), row and column arrangement (8×10), and mounting configuration (through-hole, press-fit termination). They are direct mechanical substitutes.

Q: Do these parts have the same electrical ratings?

A: Yes. Both parts are rated for 3A current and 120V voltage. Contact finish specifications, including gold plating thickness (30.0µin / 0.76µm), are identical.

Q: What is the difference in RoHS compliance?

A: The 0740611073 is RoHS non-compliant. The 0740611004 achieves ROHS3 compliance. For applications subject to RoHS3 regulatory requirements, the 0740611004 must be used.

Q: Is the packaging difference significant?

A: The 0740611073 was supplied in bulk packaging, while the 0740611004 is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Can the 0740611004 be used as a direct replacement in existing assemblies?

A: Yes. The 0740611004 is functionally and mechanically equivalent to the 0740611073 and can be used as a direct replacement in PCB assemblies without design modifications.
