Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761652808 is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Header with male pins, Impact configuration with left-side guide
• Position Count & Grid Layout: 72 positions arranged in 9 rows × 8 columns
• Pitch Specification: 0.053" (1.35mm) center-to-center spacing
• Contact Configuration: 24 differential pairs
• Mounting & Termination: Through-hole PCB mounting with press-fit termination
• Electrical & Environmental Ratings: 30V voltage rating, -55°C to +85°C operating range, UL94 V-0 flammability
• Contact Finish: Gold plating at 30.0µin thickness
• Compliance: ROHS3 compliance and MSL Level 1

The substitute part 0761653808 maintains identical electrical, mechanical, and environmental specifications while differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761653808 is a direct functional equivalent to the 0761652808. Both parts share identical electrical specifications, mechanical dimensions, contact configurations, and environmental ratings. The primary distinction is product lifecycle status: the 0761652808 is classified as Obsolete, while the 0761653808 maintains Active status with current manufacturing support.

For new designs, production runs, and long-term supply chain planning, the 0761653808 is the appropriate selection due to its Active product status and confirmed availability. Both parts meet ROHS3 compliance requirements and carry identical UL94 V-0 flammability certification, ensuring regulatory alignment across applications.

The packaging difference (bulk versus tray) does not affect electrical or mechanical performance and represents a logistics consideration only.

Frequently Asked Questions (FAQ)

Q: Can the 0761653808 be used as a direct replacement for the 0761652808 in existing designs?

A: Yes. The 0761653808 is electrically and mechanically identical to the 0761652808. All critical parameters—position count, pitch, contact configuration, voltage rating, temperature range, and contact finish—are equivalent. PCB footprints and mating interface specifications are identical.

Q: What is the significance of the Obsolete status on the 0761652808?

A: Obsolete status indicates that Molex has discontinued active manufacturing and support for this part number. The 0761653808 carries Active status, meaning it remains in current production with ongoing manufacturer support, technical documentation, and supply availability.

Q: Does the packaging difference between these parts affect compatibility?

A: No. The packaging format (bulk versus tray) is a logistics and handling consideration only. It does not affect the electrical performance, mechanical fit, or functional characteristics of the connector header itself.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 0761652808 and 0761653808 are ROHS3 compliant and carry UL94 V-0 flammability certification. The 0761653808 additionally carries REACH Unaffected status, confirming compliance with European chemical regulations.

Q: What is the differential pair configuration used in these connectors?

A: Both parts support 24 differential pairs within the 72-position grid. This configuration is suitable for high-speed signaling applications requiring controlled impedance and signal integrity across the backplane interface.

Q: What mounting considerations apply to these through-hole connectors?

A: Both parts use press-fit termination for through-hole PCB mounting. Press-fit contacts provide mechanical retention without solder, enabling automated assembly and rework capability. Ensure PCB via hole dimensions conform to Molex Impact series specifications for proper contact seating.
