Substitute Part Grouping Explanation

Substitution for the Molex 0740611124 is determined by strict equivalence across the following critical parameters:

• Connector Series and Style: VHDM 74061 series with Guide Left orientation
• Electrical Configuration: 80-position header with 8 rows × 10 columns
• Contact Pitch: 0.079" (2.00mm) spacing
• Electrical Ratings: 3A current capacity and 120V voltage rating
• Physical Characteristics: Male pins, through-hole mounting, press-fit termination
• Contact Properties: Gold plating at 30.0µin (0.76µm) thickness
• Mechanical Features: Shielded design, black color, UL94 V-0 flammability rating

The substitute part Molex 0740611004 maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional equivalence for PCB integration and system performance.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct functional equivalent for the obsolete 0740611124. Both parts maintain identical electrical and mechanical specifications, ensuring seamless integration into existing PCB designs without layout or performance modifications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 0740611004 is currently in active production status with ROHS3 compliance certification, whereas the 0740611124 is obsolete and RoHS non-compliant. For new designs or system refreshes, the 0740611004 is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part functions identically.

Packaging differs between the two parts: the 0740611004 is supplied in tube packaging, which may affect procurement workflows and inventory management practices compared to standard packaging for the 0740611124.

Frequently Asked Questions (FAQ)

Q: Can the 0740611004 be used as a direct replacement for the 0740611124 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 80-position configuration, 2.00mm pitch, 3A current rating, 120V voltage rating, gold contact finish, and shielded VHDM design. No PCB layout modifications or design changes are required.

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

A: The 0740611004 is the active production equivalent of the obsolete 0740611124. The substitute part includes ROHS3 compliance certification and is supplied in tube packaging. All functional specifications remain identical.

Q: Does the tube packaging of the 0740611004 affect compatibility?

A: No. Packaging format does not affect electrical or mechanical performance. Tube packaging is a supply and handling consideration only and does not impact connector functionality or PCB integration.

Q: Are there any electrical performance differences between these connectors?

A: No. Both parts maintain identical current ratings (3A), voltage ratings (120V), contact finish specifications (gold at 30.0µin thickness), and flammability ratings (UL94 V-0).

Q: Which part should be specified for new designs?

A: The 0740611004 should be specified for new designs due to its active product status and ROHS3 compliance. The 0740611124 is obsolete and should not be selected for new applications.
