Key Parameters

Substitute Part Grouping Explanation

The Molex 0740612501 qualifies as a direct substitute for the 0740612581 based on the following critical parameters:

Matching Electrical Specifications:

• Identical connector type: Header, Male Pins
• Identical connector style: VHDM, Guide Left
• Identical position count: 200 positions
• Identical row and column configuration: 8 rows × 25 columns
• Identical pitch: 0.079" (2.00mm)
• Identical current rating: 3A
• Identical voltage rating: 120V
• Identical contact finish: Gold at 30.0µin (0.76µm)

Matching Mechanical Specifications:

• Identical mounting type: Through Hole
• Identical termination method: Press-Fit
• Identical features: Shielded
• Identical color: Black
• Identical material flammability rating: UL94 V-0

Key Difference: The primary distinction is product status: the 0740612501 is active and available, whereas the 0740612581 is obsolete. Both parts belong to the same VHDM 74061 series and share identical electrical and mechanical characteristics, making them functionally interchangeable.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740612501 is the direct active equivalent for the obsolete 0740612581. Both parts maintain identical electrical and mechanical specifications across all critical parameters: connector configuration, position count, pitch, current and voltage ratings, contact finish, and flammability certification.

Selection of the 0740612501 is appropriate for:

• New production designs requiring VHDM 200-position backplane connectors
• Replacement of obsolete 0740612581 units in existing applications
• Designs requiring UL94 V-0 rated materials and gold-plated contacts
• Through-hole PCB mounting applications with 3A per-contact current requirements

Both parts carry identical RoHS non-compliance status and MSL rating, ensuring consistency in supply chain compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the 0740612501 be used as a direct replacement for the 0740612581?

A: Yes. The 0740612501 is a direct substitute. All electrical specifications (current rating, voltage rating, contact finish), mechanical specifications (mounting type, pitch, position count, guide configuration), and material certifications (UL94 V-0) are identical between the two parts.

Q: What is the primary reason for substitution?

A: The 0740612581 is classified as obsolete. The 0740612501 is the active equivalent from the same VHDM 74061 series, offering identical performance and compatibility.

Q: Are there packaging differences between these parts?

A: The 0740612501 is supplied in tube packaging. The original packaging specification for the 0740612581 was not provided in the technical data.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are RoHS non-compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited). Both meet UL94 V-0 material flammability standards.

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

A: Substitution is based on matching: connector type and style (VHDM, Guide Left), position count (200), pitch (2.00mm), mounting method (through-hole, press-fit), contact specifications (gold finish, 30.0µin thickness), current rating (3A), voltage rating (120V), and material certifications (UL94 V-0).
