Substitute Part Grouping Explanation

Substitution for the Molex 0761550825 is organized into two categories based on allowed electrical and mechanical parameters:

Category 1: Direct Molex Series Substitute The part 0761551825 is a direct substitute within the same Molex Impact 76155 series. This substitute maintains identical connector specifications including pitch (0.053" / 1.35mm), position count (96), row/column configuration (12×8), mounting type (through hole), termination method (press-fit), contact finish (gold), color (black), flammability rating (UL94 V-0), operating temperature range (-55°C ~ 85°C), and voltage rating (30V). The primary difference is product status: 0761551825 is active, whereas the original part is obsolete. Packaging differs (tray versus unspecified), but electrical and mechanical compatibility is complete.

Category 2: TE Connectivity High-Speed Alternative Parts 1934303-1, 1934304-1, 1934305-1, and 1934306-1 are TE Connectivity AMP Connectors from the Z-PACK TinMan series. These substitutes share the same 96-position count, 12×8 row/column configuration, through-hole mounting, press-fit termination, gold contact finish, black color, UL94 V-0 flammability rating, and MSL 1 rating. However, these parts operate at a different pitch (0.075" / 1.90mm), higher voltage rating (250V), higher current rating (0.5A), and extended operating temperature range (-65°C ~ 90°C). These differences represent design trade-offs for higher-performance applications.

Key Parameters Determining Substitution:

• Number of positions: 96 (fixed)
• Connector type: Header, male pins (fixed)
• Mounting type: Through hole (fixed)
• Termination: Press-fit (fixed)
• Contact finish: Gold (fixed)
• Color: Black (fixed)
• Flammability: UL94 V-0 (fixed)
• MSL: 1 (fixed)
• Pitch: 0.053" (1.35mm) for Category 1; 0.075" (1.90mm) for Category 2
• Voltage rating: 30V (original); 250V (Category 2)
• Current rating: Not specified (original); 0.5A (Category 2)
• Operating temperature: -55°C ~ 85°C (original); -65°C ~ 90°C (Category 2)

Engineering Selection Recommendations

For Direct Replacement (Same Electrical and Mechanical Specifications): Select Molex 0761551825 when the original design parameters must be preserved exactly. This part is active in production, ensuring long-term availability and supply chain stability. It maintains identical pitch (0.053" / 1.35mm), voltage rating (30V), operating temperature range (-55°C ~ 85°C), and all mechanical dimensions. ROHS3 compliance and MSL 1 rating are maintained. This substitute is appropriate for designs where PCB layout, mating connector specifications, and electrical performance are fixed.

For Higher-Performance Applications: Select TE Connectivity parts 1934303-1, 1934304-1, 1934305-1, or 1934306-1 when design requirements permit increased voltage rating (250V), current capacity (0.5A), and extended operating temperature range (-65°C ~ 90°C). These parts are active in production and ROHS3 compliant. The larger pitch (0.075" / 1.90mm) requires PCB layout modification but provides improved signal integrity for high-speed backplane applications. All four TE Connectivity part numbers are functionally equivalent; selection among them depends on packaging preference (all supplied in tubes) and inventory availability.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with modern manufacturing and storage requirements. No additional environmental or regulatory modifications are required when transitioning from the obsolete Molex 0761550825 to either substitute category.

Frequently Asked Questions (FAQ)

Q: Can Molex 0761551825 be used as a direct drop-in replacement for Molex 0761550825? A: Yes. Both parts share identical electrical and mechanical specifications including pitch (0.053" / 1.35mm), position count (96), voltage rating (30V), operating temperature range (-55°C ~ 85°C), contact finish (gold), flammability rating (UL94 V-0), and mounting configuration (through-hole, press-fit). The primary difference is product status: 0761551825 is active, while 0761550825 is obsolete. No design modifications are required.

Q: What are the key differences between the Molex Impact series and TE Connectivity Z-PACK TinMan series substitutes? A: The primary differences are pitch (0.053" versus 0.075"), voltage rating (30V versus 250V), current rating (not specified versus 0.5A), and operating temperature range (-55°C ~ 85°C versus -65°C ~ 90°C). Both series maintain 96 positions, 12×8 configuration, through-hole mounting, press-fit termination, gold contact finish, and UL94 V-0 flammability rating. The TE Connectivity parts are designed for higher-performance backplane applications.

Q: Do the TE Connectivity substitutes require PCB layout changes? A: Yes. The TE Connectivity parts operate at 0.075" (1.90mm) pitch compared to the original 0.053" (1.35mm) pitch. This difference requires PCB layout modification, including changes to connector footprint, trace routing, and mating connector specifications. The larger pitch may provide improved signal integrity for high-speed applications.

Q: Are all four TE Connectivity part numbers (1934303-1, 1934304-1, 1934305-1, 1934306-1) functionally equivalent? A: Yes. All four TE Connectivity parts share identical electrical and mechanical specifications. They differ only in base product number designation and inventory availability. Selection among them depends on packaging preference and supply chain considerations. Part 1934305-1 is designated for backplane connector usage.

Q: What is the packaging difference between the Molex direct substitute and TE Connectivity alternatives? A: Molex 0761551825 is supplied in trays. TE Connectivity parts 1934303-1, 1934304-1, 1934305-1, and 1934306-1 are supplied in tubes. Packaging selection depends on production volume, handling requirements, and inventory management practices.

Q: Are all substitutes ROHS3 compliant? A: Yes. The original part (Molex 0761550825), direct substitute (Molex 0761551825), and all TE Connectivity alternatives (1934303-1, 1934304-1, 1934305-1, 1934306-1) are ROHS3 compliant. MSL 1 rating is maintained across all parts, indicating unlimited shelf life under controlled storage conditions.

Q: Which substitute should be selected for a new design? A: For new designs, Molex 0761551825 is recommended if the original electrical and mechanical specifications are appropriate. This part is active in production and maintains complete compatibility with existing designs. TE Connectivity alternatives should be selected only if higher voltage rating (250V), current capacity (0.5A), or extended operating temperature range (-65°C ~ 90°C) are required, and if PCB layout modification is acceptable.
