Key Parameters

Substitute Part Grouping Explanation

The Molex 0740612501 qualifies as a direct substitute for the 0740612552 based on the following critical parameters:

• Connector Configuration: Both parts maintain identical VHDM style with guide-left orientation
• Position Count and Layout: 200 positions across 8 rows and 25 columns
• Pitch Specification: 0.079" (2.00mm) pitch ensures mechanical and electrical compatibility
• Electrical Ratings: Matching 3A current rating and 120V voltage rating
• Contact Properties: Gold plating with identical thickness (30.0µin / 0.76µm)
• Mounting and Termination: Through-hole mounting with press-fit termination
• Shielding: Both parts feature shielded construction
• Compliance: Identical UL94 V-0 flammability rating and MSL 1 classification

The primary distinction is product status: the 0740612552 is obsolete, while the 0740612501 maintains active status with improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740612501 is the designated substitute for the obsolete 0740612552. Selection criteria are based on:

• Product Status Alignment: The 0740612501 maintains active product status, ensuring long-term availability and supply chain continuity
• Electrical and Mechanical Equivalence: All critical parameters—connector style, position count, pitch, current and voltage ratings, and contact specifications—are identical
• Compliance Consistency: Both parts share identical UL94 V-0 flammability certification and MSL 1 classification
• Manufacturing Continuity: Both parts are manufactured by Molex within the same VHDM 74061 series, ensuring design consistency

For new designs or system replacements, the 0740612501 should be specified. For legacy system maintenance where the 0740612552 is currently installed, the 0740612501 provides direct functional equivalence without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 0740612501 be used as a direct replacement for the 0740612552 in existing assemblies?

A: Yes. The 0740612501 is electrically and mechanically equivalent. Both parts feature identical connector configuration, position count, pitch, current and voltage ratings, contact finish, and shielding. No PCB redesign or assembly modification is required.

Q: What is the primary reason for substitution?

A: The 0740612552 is classified as obsolete. The 0740612501 is the active equivalent, offering improved availability and supply chain reliability while maintaining identical specifications.

Q: Are there any differences in packaging between these parts?

A: The 0740612552 packaging is not specified in available documentation. The 0740612501 is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are UL94 V-0 rated, MSL 1 classified, and RoHS non-compliant. Compliance profiles are identical.

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

A: Substitution is determined by: connector style (VHDM, Guide Left), position count (200), row/column configuration (8×25), pitch (0.079" / 2.00mm), mounting type (through-hole), termination method (press-fit), current rating (3A), voltage rating (120V), and contact finish specifications (gold, 30.0µin).
