Molex 0761458608 Equivalent & Substitute Parts

Part Overview

The Molex 0761458608 is a 288-position backplane connector header with male pins, designed for through-hole PCB mounting. This connector features an Impact style with guide right configuration, 18 rows by 16 columns arrangement, and gold-plated contacts rated for 30V operation across -55°C to 85°C. The part is currently obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations where this connector type is specified.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0761458608 are qualified based on strict electrical and mechanical parameter matching within the Impact 76145 series. All substitute candidates maintain identical specifications across the following critical parameters:

288-position connector count with 18×16 row-column configuration
0.053" (1.35mm) pitch spacing
Male pin header with Impact style and guide right orientation
Through-hole press-fit termination
Gold contact finish at 30.0µin thickness
30V voltage rating and -55°C to 85°C operating temperature range
UL94 V-0 flammability classification
ROHS3 compliance and REACH unaffected status

The primary distinction between the main part and substitutes is product status and packaging configuration, not electrical or mechanical performance.

Engineering Selection Recommendations

Both 0761455608 and 0761459608 are direct functional equivalents to the obsolete 0761458608. Selection between active substitutes should be based on:

Product Status: Both substitute parts carry Active product status, ensuring continued availability and manufacturer support. The main part 0761458608 is obsolete and should not be specified for new designs.

Compliance & Certifications: All three parts maintain identical ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Packaging Consideration: The main part ships in bulk packaging, while both substitutes are supplied in tray packaging. Tray packaging provides improved handling and storage protection for high-position-count connectors.

Inventory Availability: 0761455608 maintains 850 units in stock, while 0761459608 maintains 642 units. Both provide adequate supply for production requirements.

For new designs and ongoing production, either 0761455608 or 0761459608 is acceptable. For legacy system support requiring the exact original part number, 0761458608 remains available at 852 units in current inventory.

Frequently Asked Questions (FAQ)

Q: Can 0761455608 and 0761459608 be used interchangeably with 0761458608?

A: Yes. All three parts are electrically and mechanically identical across all specified parameters including connector position count, pitch, voltage rating, temperature range, and contact finish. The substitutes differ only in product status and packaging format.

Q: Why is the main part 0761458608 marked as obsolete?

A: Obsolescence indicates the manufacturer has discontinued active production. The substitute parts 0761455608 and 0761459608 remain in active production status and are the recommended selections for new designs and ongoing procurement.

Q: Does packaging format affect connector performance?

A: No. Bulk and tray packaging formats do not affect electrical or mechanical performance. Tray packaging provides improved protection during storage and handling but does not alter connector specifications or compatibility.

Q: Are there any compliance differences between the three parts?

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

Q: What is the contact layout configuration for these connectors?

A: All three parts feature 96 differential pairs within the 288-position array, configured as 18 rows by 16 columns with 0.053" (1.35mm) pitch spacing.

Q: Can these connectors be used in applications requiring -55°C to 85°C operation?

A: Yes. All three parts are rated for the full -55°C to 85°C operating temperature range and maintain UL94 V-0 flammability classification across this entire temperature spectrum.
