Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740622604 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins; VHDM, Guide Right)
• 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)
• Operating temperature range (-55°C to 105°C)
• Contact material and finish (Gold plating)
• Shielding requirement

The substitute part 0740622504 maintains identical specifications across all these parameters, ensuring direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740622504 is the direct functional equivalent of the obsolete 0740622604. Both parts are identical in electrical performance, mechanical configuration, and physical dimensions. The primary distinction is product status and regulatory compliance.

The 0740622504 is currently in active production status, ensuring long-term availability and supply chain continuity. This part achieves ROHS3 compliance, meeting current environmental and regulatory requirements, whereas the original part does not. For new designs or system refreshes, the 0740622504 is the appropriate selection. For legacy system maintenance requiring exact historical equivalence, the 0740622604 remains functionally interchangeable where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the 0740622504 be used as a direct replacement for the 0740622604?

A: Yes. Both parts are electrically and mechanically identical. They share the same connector type, position count, pitch, current and voltage ratings, operating temperature range, and contact finish specifications. The 0740622504 is the active production equivalent.

Q: What is the difference between these two parts?

A: The 0740622604 is obsolete; the 0740622504 is active production. The 0740622504 achieves ROHS3 compliance, while the 0740622604 does not. Packaging differs: the original ships in bulk; the substitute is supplied in tubes.

Q: Are there any compatibility concerns when substituting the 0740622504 for the 0740622604?

A: No compatibility concerns exist. The parts are functionally equivalent across all specified parameters. PCB footprints, mounting hole patterns, and contact positions are identical.

Q: Does the ROHS3 compliance of the 0740622504 affect its performance in existing applications?

A: No. ROHS3 compliance indicates material composition and environmental standards. It does not alter electrical performance, current capacity, voltage rating, or operating temperature range. The part performs identically to the non-compliant version.

Q: What packaging options are available?

A: The 0740622604 is supplied in bulk packaging. The 0740622504 is supplied in tube packaging, which provides improved component protection and handling during storage and assembly.
