Key Parameters

Substitute Part Grouping Explanation

The Molex 0761653803 qualifies as a direct substitute for the 0761652803 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 matrix configuration are identical (72 positions; 9×8 layout)
• Pitch specification matches exactly (0.053" / 1.35mm)
• Contact finish, voltage rating, and temperature range are equivalent
• Mounting method and termination type are identical (Through Hole; Press-Fit)
• Compliance certifications are maintained (ROHS3, UL94 V-0, MSL 1)

The primary distinction between these parts is product status and packaging: the 0761652803 is obsolete with bulk packaging, while the 0761653803 is active with tray packaging.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761653803 is the appropriate selection for applications currently specified with the 0761652803. Both parts maintain identical electrical and mechanical specifications, including voltage rating, operating temperature range, contact finish, and compliance certifications. The 0761653803 carries active product status with established supply availability, whereas the 0761652803 is obsolete. For new designs and production continuity, the 0761653803 should be specified. Existing inventory of the 0761652803 may be utilized in applications where supply constraints exist, provided that packaging and handling procedures accommodate the bulk format.

Frequently Asked Questions (FAQ)

Q: Are the 0761652803 and 0761653803 electrically interchangeable?

A: Yes. Both parts are identical in electrical specifications, including voltage rating (30V), contact finish (gold, 30.0µin), and operating temperature range (-55°C ~ 85°C).

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The 0761652803 is obsolete with bulk packaging, while the 0761653803 is active with tray packaging. All functional and mechanical parameters are equivalent.

Q: Can I use the 0761652803 in new designs?

A: The 0761652803 is classified as obsolete. For new designs, the 0761653803 should be specified to ensure long-term supply availability and support.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0761652803 and 0761653803 are ROHS3 compliant with UL94 V-0 material flammability rating.

Q: Does packaging affect connector performance?

A: No. Packaging format (bulk versus tray) does not affect electrical or mechanical performance. Packaging selection is determined by handling, storage, and assembly process requirements.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
