Key Parameters

Substitute Part Grouping Explanation

The Molex 0761453604 qualifies as a direct substitute for the 0761452604 based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type, style, and orientation remain unchanged (Header, Male Pins, Impact, Guide Left)
• Position count and array configuration are identical (288 positions, 18 rows × 16 columns)
• Pitch specification matches exactly (0.053" / 1.35mm)
• Contact material and finish are equivalent (Gold, 30.0µin thickness)
• Electrical ratings are identical (30V, -55°C to 85°C operating range)
• Mounting method and termination type are the same (Through Hole, Press-Fit)
• Compliance certifications are maintained (ROHS3, UL94 V-0)

The primary distinction between these parts is product status: the 0761453604 is active and available, while the 0761452604 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761453604 is the appropriate selection for applications currently using or requiring the 0761452604. Both parts maintain identical electrical and mechanical specifications, ensuring direct compatibility in PCB designs and assembly processes. The 0761453604 carries active product status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete 0761452604. Both parts satisfy ROHS3 compliance and UL94 V-0 flammability requirements, maintaining regulatory alignment for industrial and commercial applications. The packaging difference (tray for the substitute) does not affect functional performance and represents a standard distribution format for active components.

Frequently Asked Questions (FAQ)

Q: Can the 0761453604 be used as a direct replacement for the 0761452604 in existing designs?

A: Yes. The 0761453604 is electrically and mechanically identical to the 0761452604. All connector specifications, pin configurations, electrical ratings, and mounting characteristics are equivalent. No design modifications are required.

Q: What is the primary reason for substitution?

A: The 0761452604 is classified as obsolete. The 0761453604 is the active equivalent from the same manufacturer and series, ensuring continued availability and supply chain stability.

Q: Are there differences in compliance or certifications?

A: No. Both parts are ROHS3 compliant and carry UL94 V-0 flammability ratings. Regulatory and environmental compliance requirements are identical.

Q: Does packaging format affect compatibility?

A: No. The 0761453604 is supplied in tray packaging, a standard format for active components. Packaging does not impact electrical performance, mechanical fit, or PCB assembly compatibility.

Q: What parameters must remain identical for substitution to be valid?

A: Position count (288), pitch (0.053" / 1.35mm), row/column configuration (18 × 16), connector style (Impact, Guide Left), mounting type (Through Hole), contact finish (Gold), and electrical ratings (30V, -55°C to 85°C) must all match exactly.
