Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761652807 is determined by strict equivalence across the following critical parameters:

• Connector Type and Style: Header with male pins, Impact configuration with left-side guide
• Position Count and Grid Layout: 72 positions arranged in 9 rows × 8 columns
• Pitch Specification: 0.053" (1.35mm) center-to-center spacing
• Mounting and Termination: Through-hole PCB mounting with press-fit termination
• Electrical Characteristics: 24 differential pair contact layout, 30V voltage rating, gold-plated contacts at 30.0µin thickness
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, MSL 1 rating
• Operating Conditions: -55°C to 85°C temperature range

The substitute part 0761653807 maintains identical electrical, mechanical, and environmental specifications while differing only in product status (Active vs. Obsolete) and packaging format (Tray vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761653807 is the direct functional equivalent for the obsolete 0761652807. Both components are manufactured by Molex within the Impact 76165 series and maintain identical electrical, mechanical, and environmental specifications.

Selection of the 0761653807 is supported by:

• Product Status: The substitute carries Active status, ensuring ongoing availability and manufacturing support from Molex
• Compliance Alignment: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification
• Electrical Equivalence: Identical voltage rating (30V), contact configuration (24 differential pairs), and contact finish specifications (gold, 30.0µin thickness)
• Mechanical Compatibility: Identical pitch (0.053"), position count (72), grid layout (9×8), and through-hole press-fit termination
• Environmental Suitability: Both parts operate across the -55°C to 85°C temperature range with MSL 1 rating

The only differences are packaging format (Tray for the substitute) and product lifecycle status. These differences do not affect functional or electrical performance in PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the 0761653807 be used as a direct replacement for the 0761652807 in existing PCB designs?

A: Yes. The 0761653807 maintains identical connector type, position count, pitch, mounting method, and electrical specifications. No PCB layout or design modifications are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 0761652807 is classified as Obsolete, indicating Molex has discontinued active manufacturing and support. The 0761653807 carries Active status, meaning Molex continues to manufacture and support this part. For new designs or ongoing production, the Active part ensures supply chain continuity.

Q: Are there any differences in contact finish or plating between these two parts?

A: No. Both parts feature gold-plated contacts with identical finish thickness of 30.0µin (0.76µm), ensuring equivalent electrical performance and corrosion resistance.

Q: Does the packaging difference (Tray vs. standard) affect component performance?

A: No. Packaging format affects only logistics and handling. The electrical and mechanical properties of the connector header remain identical regardless of packaging type.

Q: Are both parts compliant with current environmental and safety standards?

A: Yes. Both the 0761652807 and 0761653807 are ROHS3 compliant and carry UL94 V-0 flammability certification. Both maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the pitch specification, and why is it critical for substitution?

A: Both parts feature 0.053" (1.35mm) pitch spacing. This specification is critical because it determines PCB hole spacing and connector alignment. Pitch equivalence is mandatory for direct substitution.

Q: Can the 0761653807 handle the same voltage and temperature ranges as the original part?

A: Yes. Both parts are rated for 30V operation and function across the -55°C to 85°C temperature range, ensuring equivalent performance in all specified operating conditions.
