Substitute Part Grouping Explanation

Substitute parts for the Amphenol ICC 91036-125 are identified based on strict equivalence of core electrical and mechanical parameters. The substitution criteria are:

• Connector type must be Header
• Contact type must be Male Pin
• Mating pitch must be 0.050" (1.27mm)
• Number of positions must be 50
• Number of rows must be 2
• Row spacing must be 0.050" (1.27mm)
• Style must be Board to Board
• Shrouding must be Shrouded - 4 Wall
• Mounting type must be Surface Mount
• Termination must be Solder
• Fastening type must be Push-Pull

The TE Connectivity AMP Connectors part number 5-104693-5 meets all these core requirements and qualifies as a direct substitute within the AMPMODU 50/50 Grid series.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 91036-125 and TE Connectivity 5-104693-5 are active production parts meeting UL94 V-0 flammability requirements. The TE Connectivity substitute offers ROHS3 compliance, which may be advantageous for applications subject to RoHS regulations. The Amphenol ICC part supports a higher maximum operating temperature of 130°C compared to 105°C for the TE Connectivity alternative, making it more suitable for elevated-temperature applications. The TE Connectivity part specifies a current rating of 0.5A per contact, providing explicit electrical performance data. Mated stacking heights are equivalent within 0.02mm tolerance. Selection between these parts should be based on specific application temperature requirements, regulatory compliance mandates, and electrical performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-104693-5 be used as a direct replacement for the Amphenol ICC 91036-125?

A: Yes, within the constraints of your application's operating temperature and regulatory requirements. Both parts share identical core mechanical and electrical parameters: 50-position, 1.27mm pitch, board-to-board, surface mount headers with push-pull fastening and 4-wall shrouding. Verify that your application's maximum operating temperature does not exceed 105°C if using the TE Connectivity substitute, as the Amphenol ICC part supports operation to 130°C.

Q: What are the key differences between these two connector headers?

A: Primary differences include operating temperature range (Amphenol ICC: -55°C to 130°C; TE Connectivity: -65°C to 105°C), insulation material (Amphenol ICC: Thermoplastic, Glass Filled; TE Connectivity: Liquid Crystal Polymer), contact shape (Amphenol ICC: Square; TE Connectivity: Circular), and RoHS compliance status (Amphenol ICC: non-compliant; TE Connectivity: ROHS3 compliant). Mating contact length differs by 0.010" (0.25mm).

Q: Are there any compatibility concerns with PCB footprints?

A: Mated stacking heights are nearly identical (9.93mm vs. 9.91mm), and both parts maintain the same 1.27mm pitch and 50-position configuration. Verify that your PCB footprint accommodates the slight differences in contact length and insulation height. The circular contact shape of the TE Connectivity part may require footprint validation against the square contact design of the Amphenol ICC part.

Q: Which part should I select for high-temperature applications?

A: The Amphenol ICC 91036-125 is rated to 130°C and is the appropriate choice for applications requiring sustained operation above 105°C. The TE Connectivity 5-104693-5 is limited to 105°C maximum operating temperature.

Q: Does RoHS compliance affect my selection?

A: If your application or end-market requires RoHS3 compliance, the TE Connectivity 5-104693-5 is the compliant option. The Amphenol ICC 91036-125 is RoHS non-compliant. Verify regulatory requirements for your specific application before selection.
