Amphenol ICC 68405-372 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68405-372 is a rectangular connector header, right-angle mounted, with 72 positions at 0.100" (2.54mm) pitch. This through-hole component is part of the BERGSTIK® II series and is designed for board-to-board applications. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Substitute parts must maintain compatibility across pitch, position count, row configuration, and mounting style while accommodating minor variations in electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 68405-372 is determined by the following critical parameters:

Primary Matching Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 72
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Length - Mating: 0.230" (5.84mm)
• Contact Shape: Square
• Style: Board to Board or Board to Board/Cable

Secondary Compatibility Parameters:

• Insulation Height (tolerance range acceptable)
• Contact Finish - Mating (Gold acceptable)
• Contact Material (Phosphor Bronze or Copper Alloy acceptable)
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black

Substitute parts meeting all primary criteria are considered functionally equivalent. Variations in contact post length, contact finish thickness, and operating temperature ranges do not affect mating compatibility but may impact application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (72-Position, Exact Match):

The 3M 2372-5121-TG, Samtec TSW-136-08-F-D-RA, and Samtec TSW-136-10-G-D-RA are direct functional equivalents to the Amphenol ICC 68405-372. All three maintain the critical 72-position, 2-row, 0.100" pitch configuration with identical mating contact length and right-angle through-hole mounting. These parts are currently in active production status, ensuring long-term availability.

For new designs requiring RoHS compliance, the Samtec TSW-136-08-F-D-RA and TSW-136-10-G-D-RA are ROHS3 compliant, while the 3M 2372-5121-TG remains RoHS non-compliant. The TE Connectivity 4-103740-0 is RoHS compliant but features 80 positions instead of 72, making it suitable only for applications where the additional 8 positions can be accommodated or left unused.

Secondary Consideration (80-Position Alternative):

The TE Connectivity 4-103740-0 offers an alternative for applications where position count flexibility exists. This part maintains all critical mating parameters but provides 80 positions, requiring PCB layout modification. This option is suitable only when the additional positions do not conflict with board design constraints.

Compliance and Availability:

All substitute parts carry UL94 V-0 flammability ratings and black insulation, matching the original specification. The Samtec parts offer extended operating temperature ranges (-55°C to 125°C) compared to the 3M part (-55°C to 105°C), providing additional thermal margin for demanding applications. Current rating specifications vary; the original part specifies 5A, while 3M and TE parts specify 3A. Applications requiring the full 5A rating should be evaluated against actual circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3M 2372-5121-TG directly replace the Amphenol ICC 68405-372 on existing PCBs?

A: Yes. The 3M 2372-5121-TG maintains identical pitch (0.100"), position count (72), row configuration (2 rows), mating contact length (0.230"), and right-angle through-hole mounting. Insulation height variation (0.242" vs. 0.190") does not affect mating compatibility. The part is a direct mechanical and electrical substitute.

Q: What is the difference between the Samtec TSW-136-08-F-D-RA and TSW-136-10-G-D-RA?

A: Both Samtec parts are functionally equivalent for mating purposes. The primary difference is contact post length: the TSW-136-08-F-D-RA has 0.090" posts, while the TSW-136-10-G-D-RA has 0.390" posts. Selection depends on PCB thickness and solder joint requirements. The TSW-136-10-G-D-RA also features gold-plated posts versus tin-plated posts on the TSW-136-08-F-D-RA.

Q: Why does the TE Connectivity 4-103740-0 have 80 positions instead of 72?

A: The TE Connectivity 4-103740-0 is part of the AMPMODU Mod II series with a different position configuration. While it maintains the same 0.100" pitch and 2-row layout, it accommodates 80 positions. This part is suitable only for applications where PCB layout can accommodate the additional positions or where unused positions are acceptable.

Q: Are there current rating differences between the main part and substitutes?

A: Yes. The Amphenol ICC 68405-372 specifies 5A current rating, while the 3M 2372-5121-TG and TE Connectivity 4-103740-0 specify 3A. The Samtec parts do not specify current rating. Applications requiring sustained 5A operation should evaluate actual circuit current draw against substitute specifications.

Q: Which substitute offers the best RoHS compliance?

A: The Samtec TSW-136-08-F-D-RA and TSW-136-10-G-D-RA are both ROHS3 compliant. The TE Connectivity 4-103740-0 is RoHS compliant. The 3M 2372-5121-TG is RoHS non-compliant. For new designs requiring RoHS compliance, Samtec or TE Connectivity options are recommended.

Q: What is the operating temperature range for each substitute?

A: The 3M 2372-5121-TG operates from -55°C to 105°C. The TE Connectivity 4-103740-0 operates from -65°C to 105°C. Both Samtec parts (TSW-136-08-F-D-RA and TSW-136-10-G-D-RA) operate from -55°C to 125°C. The original Amphenol ICC 68405-372 does not specify operating temperature. Applications in extreme temperature environments should select based on these ranges.

Q: Can I use these substitutes interchangeably on the same PCB?

A: The 3M 2372-5121-TG, Samtec TSW-136-08-F-D-RA, and Samtec TSW-136-10-G-D-RA are mechanically and electrically interchangeable for 72-position applications. The TE Connectivity 4-103740-0 is not interchangeable due to its 80-position configuration. Samtec post length variations (0.090" vs. 0.390") may affect solder joint characteristics depending on PCB thickness.
