Engineering Selection Recommendations

Primary Substitutes (Closest Dimensional Match):

The 68497-136, 68497-236, 68497-536H, and 68497-636 variants provide the closest overall contact length (0.612" / 15.54mm) to the original 926141-01-36-EU (0.628" / 15.95mm). These parts maintain active product status and are available in volume. Selection between these variants depends on contact finish thickness requirements: 30.0µin (0.76µm) for 68497-136 and 68497-636, or 15.0µin (0.38µm) for 68497-236 and 68497-536H.

Extended Mating Contact Length Option:

The 68653-136, 68653-136H, and 68653-236 series offer extended mating contact length (0.540" / 13.72mm) and overall contact length (0.735" / 18.67mm), suitable for applications requiring deeper insertion or higher contact engagement. These parts are active and available in high inventory quantities.

Longer Mating Contact Option:

The 68487-136 and 68487-236 provide extended mating contact length (0.495" / 12.57mm) with increased overall contact length (0.705" / 17.91mm), appropriate for applications with specific depth requirements.

RoHS Compliant Alternative:

The 68604-436HLF is the only RoHS-compliant substitute in this group. It features tin plating instead of gold, operates across an extended temperature range (-65°C ~ 125°C), and supports 3A current rating. This part is suitable for applications with RoHS compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 3M 926141-01-36-EU with any of the listed Amphenol ICC (FCI) parts?

A: Direct replacement depends on your specific application requirements. All listed substitutes maintain the core 36-position, 2.54mm pitch, through-hole solder configuration. However, contact length variations (ranging from 0.380" to 0.540" mating length) may affect board layout and mating depth. Verify your PCB design accommodates the selected substitute's dimensional specifications.

Q: What is the difference between the contact finish options?

A: The original 926141-01-36-EU uses gold plating at 10.0µin (0.25µm) thickness. Substitute options include gold plating at 15.0µin (0.38µm) or 30.0µin (0.76µm) thickness, offering enhanced durability and corrosion resistance. The 68604-436HLF uses tin plating at 100.0µin (2.54µm), providing different electrical and environmental characteristics suitable for RoHS-compliant applications.

Q: Are there temperature rating differences I should consider?

A: The original part operates from -40°C to 105°C. Most Amphenol ICC (FCI) BERGSTIK® II substitutes do not specify operating temperature ranges in the provided data. The 68604-436HLF explicitly supports -65°C to 125°C, making it suitable for extended temperature applications.

Q: Which substitute should I choose for RoHS compliance?

A: The 68604-436HLF is the only RoHS-compliant option among the listed substitutes. All other Amphenol ICC (FCI) parts are marked as RoHS non-compliant. If RoHS compliance is mandatory, the 68604-436HLF is the required selection, noting its tin finish and extended temperature range specifications.

Q: How do contact length variations affect my design?

A: Contact length determines how far the male pins extend from the insulation body. Shorter mating contact lengths (68604-436HLF at 0.380") require less insertion depth, while longer lengths (68653 series at 0.540") provide deeper engagement. Post length affects solder joint formation on the PCB. Verify your board thickness and connector pocket depth accommodate the selected part's dimensions.

Q: What is the difference between the 68497 and 68653 series?

A: Both are BERGSTIK® II series headers with identical pitch and position count. The primary difference is contact length: 68497 series has 0.427" mating contact length, while 68653 series has 0.540" mating contact length. The 68653 series provides extended engagement for applications requiring deeper insertion or higher contact force.

Q: Can I mix different substitute part numbers in the same design?

A: All listed substitutes maintain identical pitch (2.54mm), position count (36), and core electrical characteristics. However, mixing parts with different contact lengths in the same assembly may create mechanical inconsistencies. Standardize on a single part number for each connector location in your design.
