Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761652103 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of positions: 90
• Connector type: Header, Male Pins
• Mounting type: Through Hole
• Termination method: Press-Fit
• Contact finish: Gold
• RoHS compliance: ROHS3 Compliant

Secondary Compatibility Considerations:

• Operating temperature range must encompass or exceed the original specification (-55°C ~ 85°C)
• Voltage rating must meet or exceed 30V
• Pitch and row/column configuration must accommodate PCB layout requirements

The Molex 0761653103 qualifies as a direct equivalent, maintaining identical electrical and mechanical specifications while offering active product status. The TE Connectivity 1934339-1 functions as a manufacturer-recommended alternative, though it introduces pitch variation (0.075" vs. 0.053") and enhanced voltage rating (250V vs. 30V), requiring PCB layout verification before implementation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The Molex 0761653103 is the recommended substitute for the obsolete Molex 0761652103. Both parts maintain identical electrical and mechanical specifications, including pitch (0.053"), voltage rating (30V), and operating temperature range (-55°C ~ 85°C). The 0761653103 carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. No PCB layout modifications are required.

For Alternative Implementation: The TE Connectivity 1934339-1 serves as a manufacturer-recommended alternative with enhanced specifications. This part offers extended operating temperature range (-65°C ~ 90°C) and significantly higher voltage rating (250V). However, the pitch difference (0.075" vs. 0.053") necessitates PCB layout verification to confirm mechanical compatibility with existing mounting holes and trace routing. This option is suitable for new designs or systems where PCB modification is feasible.

Compliance Considerations: All three parts maintain ROHS3 compliance and UL94 V-0 flammability rating, supporting regulatory requirements across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761653103 be used as a direct drop-in replacement for the 0761652103? A: Yes. The 0761653103 maintains identical pitch (0.053"), position count (90), voltage rating (30V), and operating temperature range (-55°C ~ 85°C). No PCB modifications are required.

Q: What is the primary difference between the Molex 0761653103 and TE Connectivity 1934339-1? A: The pitch differs: Molex uses 0.053" (1.35mm) while TE Connectivity uses 0.075" (1.90mm). This spacing difference affects PCB hole placement and requires layout verification before substitution.

Q: Is the TE Connectivity 1934339-1 suitable for applications requiring the original 30V rating? A: Yes. The TE Connectivity part exceeds the voltage requirement with a 250V rating, providing additional design margin. However, PCB layout compatibility must be confirmed due to pitch variation.

Q: Are all three parts RoHS compliant? A: Yes. The Molex 0761652103, Molex 0761653103, and TE Connectivity 1934339-1 are all ROHS3 compliant.

Q: What packaging formats are available for these parts? A: The Molex 0761652103 is supplied without specified packaging. The Molex 0761653103 is packaged in trays. The TE Connectivity 1934339-1 is supplied in tubes.

Q: Can the TE Connectivity 1934339-1 operate across the same temperature range as the original part? A: The TE Connectivity part operates across -65°C ~ 90°C, which exceeds the original specification of -55°C ~ 85°C, providing extended thermal performance.
