Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0761558804 are qualified based on strict electrical and mechanical parameter matching within the Impact 76155 series. The following criteria determine substitution eligibility:

• Identical number of positions (96)
• Identical pitch specification (0.053" / 1.35mm)
• Identical connector type and style (Header, Male Pins; Impact, Guide Right)
• Identical mounting type (Through Hole) and termination method (Press-Fit)
• Identical contact finish specification (Gold, 30.0µin)
• Identical voltage and temperature ratings (30V, -55°C ~ 85°C)
• Identical material flammability rating (UL94 V-0)
• ROHS3 compliance maintained

The substitute parts 0761555804 and 0761559804 meet all these criteria and are classified as active products, providing design continuity for the obsolete 0761558804.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 0761555804 and 0761559804 are direct functional equivalents to the obsolete 0761558804. Selection between the two active alternatives should be based on procurement availability and packaging requirements, as both are classified as active products with full ROHS3 compliance and REACH unaffected status.

The 0761555804 carries 823 units in current inventory, while the 0761559804 carries 1068 units. Both maintain identical electrical and mechanical specifications, ensuring seamless integration into existing PCB designs without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can 0761555804 and 0761559804 be used interchangeably with 0761558804?

A: Yes. Both substitute parts meet all electrical and mechanical parameters of the obsolete 0761558804, including connector position count, pitch, contact finish, voltage rating, temperature range, and flammability classification.

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

A: The substitute parts differ only in packaging format (Tray) and current inventory levels. All electrical and mechanical specifications are identical.

Q: Why is the original 0761558804 classified as obsolete?

A: Product status reflects Molex's manufacturing and support lifecycle. The active substitute parts 0761555804 and 0761559804 provide equivalent functionality for new designs and ongoing production.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All three parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and identical moisture sensitivity level (MSL 1 - Unlimited).

Q: Does packaging format affect electrical performance?

A: No. Packaging format (bulk versus tray) does not affect connector electrical or mechanical performance. Selection should be based on procurement and assembly process requirements.
