Amphenol ICC 86381-426 Rectangular Connector Header — Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 86381-426 is a through-hole, right-angle rectangular connector header with 26 positions arranged in 2 rows at 0.100" (2.54mm) pitch. Classified as part of the BERGSTIK® II series, this component is designed for board-to-board applications requiring press-fit and solder termination. The part maintains active product status with 829 units in current inventory.

Substitute parts become necessary when addressing supply chain constraints, design revisions requiring alternative contact finishes or insulation materials, or when operational temperature ranges exceed the original specification. The substitute parts listed maintain electrical and mechanical compatibility while offering variations in contact materials, finishes, and thermal performance.

Substitute Part Grouping Explanation

Substitution eligibility for the 86381-426 is determined by strict adherence to the following core parameters:

Connector Type: Header (with or without breakaway feature)
Contact Type: Male Pin
Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 26
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole, Right Angle
Contact Shape: Square
Material Flammability Rating: UL94 V-0
Moisture Sensitivity Level: 1 (Unlimited)

All four substitute parts meet these mandatory criteria. Variations in contact finish (tin vs. gold), contact material (phosphor bronze vs. brass vs. copper alloy), insulation material composition, and operating temperature ranges are permitted within the substitution framework, as these parameters do not affect mechanical fit or basic electrical function in standard applications.

Engineering Selection Recommendations

All substitute parts maintain active product status and meet the core mechanical and electrical compatibility requirements for the 86381-426. Selection among substitutes should be based on the following compliance and certification factors:

RoHS Compliance: The original 86381-426 is RoHS non-compliant. All four substitute parts (1-826634-3, 6-146310-3, TSW-113-22-G-D-RA, and TSW-113-22-L-D-RA) are ROHS3 compliant. Applications requiring RoHS compliance must use one of the substitute parts.

Operating Temperature Range: The 86381-426 does not specify an operating temperature range. The TE Connectivity parts (1-826634-3 and 6-146310-3) operate from -65°C to 105°C. The Samtec TSW series parts (TSW-113-22-G-D-RA and TSW-113-22-L-D-RA) operate from -55°C to 125°C, providing extended high-temperature capability.

Contact Finish and Material: The original part features tin-plated phosphor bronze contacts. Substitute parts offer gold-plated contacts with varying base materials (brass, copper alloy, or phosphor bronze). Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments.

Termination Options: The 86381-426 supports both press-fit and solder termination. The TE Connectivity 1-826634-3 supports solder termination only. The TE Connectivity 6-146310-3 and all Samtec parts support solder termination; the 6-146310-3 also supports press-fit termination.

Current Rating: The TE Connectivity 1-826634-3 is rated for 5A, and the 6-146310-3 is rated for 3A. The original part and Samtec parts do not specify current ratings. Applications with defined current requirements should reference the rated values.

Frequently Asked Questions (FAQ)

Q: Can the 86381-426 be directly replaced with any of the listed substitute parts?

A: Yes, all four substitute parts are mechanically and electrically compatible with the 86381-426 due to matching pitch (0.100"), position count (26), row configuration (2 rows), and mounting type (through-hole, right-angle). Physical fit and mating interface are preserved across all substitutes.

Q: What is the primary reason to substitute the 86381-426?

A: The most common reason is RoHS compliance. The original part is RoHS non-compliant, while all substitutes are ROHS3 compliant. Additional reasons include extended operating temperature requirements (Samtec TSW series to 125°C) or specific termination method preferences.

Q: Are there differences in contact length between the main part and substitutes?

A: Yes. The 86381-426 has a mating contact length of 0.250" (6.35mm) and post length of 0.120" (3.05mm). The TE Connectivity 1-826634-3 has slightly longer mating contacts (0.264" / 6.70mm). The TE Connectivity 6-146310-3 and both Samtec parts have shorter mating contacts (0.230" / 5.84mm). These variations are within acceptable tolerance for standard board-to-board applications but should be verified for designs with tight mechanical constraints.

Q: What is the difference between the two Samtec TSW parts?

A: Both TSW-113-22-G-D-RA and TSW-113-22-L-D-RA are identical except for post contact finish. The TSW-113-22-G-D-RA has gold-plated posts, while the TSW-113-22-L-D-RA has tin-plated posts. Both have gold-plated mating contacts and operate from -55°C to 125°C.

Q: Does packaging type affect substitution eligibility?

A: No. The 86381-426 is supplied in bulk packaging, while the TE Connectivity 6-146310-3 is supplied in tray packaging. All other parts are bulk. Packaging affects logistics and handling but does not affect electrical or mechanical compatibility.

Q: Which substitute part most closely matches the original 86381-426 specifications?

A: The TE Connectivity 6-146310-3 most closely matches the original part, with identical contact post length (0.120" / 3.05mm), support for both press-fit and solder termination, and black insulation color. However, it has a lower current rating (3A vs. unspecified) and slightly different insulation height.

Q: Are all substitute parts suitable for high-temperature applications?

A: The Samtec TSW series (TSW-113-22-G-D-RA and TSW-113-22-L-D-RA) are rated to 125°C, making them suitable for extended high-temperature operation. The TE Connectivity parts are rated to 105°C. The original 86381-426 does not specify an operating temperature range.
