Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0740612504 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins; VHDM, Guide Left)
• Position count and array configuration (200 positions; 8 rows × 25 columns)
• Pitch specification (0.079" / 2.00mm)
• Mounting and termination method (Through Hole; Press-Fit)
• Electrical ratings (3A current; 120V voltage)
• Contact material and finish (Gold plating, 30.0µin thickness)
• Shielding requirement
• Physical color and form factor (Black)

The substitute part must maintain identical mechanical and electrical characteristics to ensure direct PCB compatibility without design modification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740612501 is the direct functional equivalent of the 0740612504. Both parts are identical in electrical performance, mechanical dimensions, and contact specifications. The primary distinction is product status: the 0740612504 is obsolete, while the 0740612501 is active and currently manufactured.

For new designs or component replenishment, the 0740612501 is the appropriate selection. It maintains full compatibility with existing PCB layouts and assembly processes designed for the 0740612504. The packaging difference (Tube versus Bulk) reflects standard commercial availability for active products and does not affect functional performance.

Both parts carry identical compliance certifications (UL94 V-0, MSL 1) and RoHS non-compliance status. No design modifications or re-qualification are required when transitioning from the obsolete part number to the active substitute.

Frequently Asked Questions (FAQ)

Q: Can the 0740612501 be used as a direct replacement for the 0740612504 on existing PCBs?

A: Yes. The 0740612501 is mechanically and electrically identical to the 0740612504. Pin count, pitch, mounting holes, contact layout, and electrical ratings are equivalent. No PCB redesign is necessary.

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

A: The 0740612504 is classified as obsolete and is no longer in active production. The 0740612501 is the current active equivalent from Molex, manufactured to the same specifications. The packaging format differs (Bulk versus Tube), but the connector itself is identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry the same UL94 V-0 flammability rating, MSL 1 moisture sensitivity level, and RoHS non-compliance status. Electrical and thermal performance specifications are identical.

Q: Does the packaging change affect connector performance?

A: No. Packaging format (Tube versus Bulk) is a commercial consideration only and does not affect the connector's electrical, mechanical, or thermal characteristics.

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

A: Substitution is determined by: connector type and style (VHDM Header, Male Pins, Guide Left), position count (200), array configuration (8×25), pitch (2.00mm), mounting method (Through Hole, Press-Fit), current rating (3A), voltage rating (120V), contact finish (Gold, 30.0µin), and shielding. Any deviation in these parameters requires re-evaluation of compatibility.
