Molex 0740612554 VHDM 200-Position Backplane Connector Header

Part Overview

The Molex 0740612554 is a 200-position VHDM backplane connector header designed for through-hole PCB mounting applications. This component features male pins with shielding, gold-plated contacts, and a guide-left configuration. The part is classified as obsolete, making identification of compatible alternatives essential for ongoing system support and new design implementations. The active substitute part maintains identical electrical and mechanical specifications while offering current availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740612554 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)
• Contact pitch (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)
• Mechanical features (Shielded; Black color)
• Compliance standards (UL94 V-0 flammability rating)

The substitute part 0740612501 meets all these criteria, differing only in product status (Active vs. Obsolete) and packaging configuration (Tube vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740612501 is the direct functional equivalent of the 0740612554. Both parts are manufactured by Molex within the VHDM 74061 series and maintain identical electrical, mechanical, and dimensional specifications. The primary distinction is product lifecycle status: the 0740612554 is obsolete, while the 0740612501 carries active product status with current manufacturing support.

For new designs and ongoing system support, the 0740612501 is the appropriate selection. Both parts share identical compliance certifications (UL94 V-0 flammability rating, EAR99 export classification) and non-compliant RoHS status. The packaging difference (Tube for 0740612501 versus standard for 0740612554) does not affect functional compatibility or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can the 0740612501 be used as a direct replacement for the 0740612554 in existing designs?

A: Yes. The 0740612501 is electrically and mechanically identical to the 0740612554. All contact positions, pitch spacing, mounting holes, and electrical ratings are equivalent. No design modifications are required.

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

A: The 0740612554 is classified as obsolete, while the 0740612501 is an active product. Both parts are from the same VHDM 74061 series and share identical specifications. The 0740612501 includes tube packaging, whereas the 0740612554 uses standard packaging.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: UL94 V-0 flammability rating, EAR99 export classification, and HTSUS code 8536.69.4040. Both are RoHS non-compliant.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these connectors be used in applications requiring RoHS compliance?

A: No. Both the 0740612554 and 0740612501 are RoHS non-compliant. Applications with RoHS requirements require alternative connector solutions.

Q: What is the current and voltage rating for this connector header?

A: The connector is rated for 3A current and 120V voltage. These ratings apply to both the main part and substitute.
