Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740622522 is determined by strict equivalence across the following critical parameters:

• Connector type, style, and orientation (Header, Male Pins; VHDM, Guide Right)
• 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; 30.0µin thickness)
• Environmental specifications (Operating temperature -55°C to 105°C; UL94 V-0)

The substitute parts identified—Molex 0740622502 and Molex 0740622504—maintain complete electrical and mechanical equivalence across all specified parameters. Both substitutes are classified as active products, addressing the obsolescence status of the original component. Packaging format (Tube) differs from the main part but does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts provide direct functional equivalence to the obsolete Molex 0740622522. Selection between the two active alternatives is determined by regulatory compliance requirements:

Molex 0740622502 maintains RoHS non-compliant status consistent with the original component, suitable for applications where legacy compliance posture is maintained or where RoHS exemptions apply.

Molex 0740622504 achieves ROHS3 compliance, providing regulatory alignment for new designs or applications subject to RoHS3 requirements. This part is recommended for applications requiring current environmental compliance certifications.

Both parts carry identical electrical and mechanical specifications, ensuring direct pin-for-pin and form-factor compatibility. Inventory availability differs between substitutes, with 0740622504 offering higher stock levels (2360 units) compared to 0740622502 (776 units).

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 0740622502 and 0740622504 electrically interchangeable with 0740622522?

A: Yes. Both substitute parts maintain identical electrical ratings (3A current, 120V voltage), contact specifications (gold finish, 30.0µin thickness), and operating temperature range (-55°C to 105°C). They are direct electrical equivalents.

Q: What is the primary difference between the two substitute parts?

A: The primary difference is RoHS compliance status. Molex 0740622504 is ROHS3 compliant, while Molex 0740622502 maintains RoHS non-compliant status. All other electrical and mechanical parameters are identical.

Q: Can I use these substitutes in existing PCB designs without modification?

A: Yes. Both substitute parts are mechanically and electrically equivalent to the original component. They feature identical pitch (0.079" / 2.00mm), position count (200), array configuration (8 rows × 25 columns), and through-hole mounting specifications. No PCB redesign is required.

Q: Does packaging format affect component compatibility?

A: No. Packaging format (Tube) is a logistics consideration only and does not affect electrical or mechanical compatibility. The connector itself remains functionally identical regardless of packaging.

Q: Which substitute should I select for new production?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify Molex 0740622504. For applications where RoHS non-compliant status is acceptable, either part is suitable. Verify compliance requirements for your specific application.
