Amphenol ICC 67997-626 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 67997-626 is a rectangular connector header from the BERGSTIK® II series, configured as a through-hole, vertical-mount component with 26 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector features male pins with gold-plated mating contacts and phosphor bronze contact material, rated for 3A current and operating temperatures from -65°C to 130°C.

The 67997-626 carries an obsolete product status. Locating equivalent and substitute parts is necessary to support ongoing maintenance, repair, and new design implementations where this connector type remains functionally required but original inventory is depleted or unavailable.

Substitute Part Grouping Explanation

Substitution of the 67997-626 is determined by strict alignment of the following electrical and mechanical parameters:

Connector configuration: 26 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
Contact type: Male pin headers with push-pull fastening
Mounting and termination: Through-hole solder termination
Current and temperature ratings: 3A minimum current capacity; operating range encompassing or exceeding -65°C to 130°C
Contact material and finish: Phosphor bronze or copper alloy contacts with gold or tin mating finish
Flammability compliance: UL94 V-0 rating

Substitute parts are grouped into two categories based on product status and compliance posture:

Category A - Active Status, Modern Compliance: TE Connectivity AMPMODU Mod II series (6-146254-3, 6-146256-3, 6-146257-3, 6-146261-3) and Samtec Flex Stack HMTSW series (HMTSW-113-07-G-D-205, HMTSW-113-07-L-D-210). These parts meet current RoHS3 compliance requirements and maintain active manufacturing status.

Category B - Active Status, Legacy Compliance: 3M 2300 series (2326-6121TB) and Preci-Dip 450 series (450-10-226-00-013101, 450-80-226-00-001101, 450-80-226-00-013101). These parts are actively manufactured but carry non-compliant or undefined RoHS status, suitable for legacy system support.

Engineering Selection Recommendations

For new designs and systems requiring RoHS3 compliance, select from the TE Connectivity AMPMODU Mod II series (6-146256-3, 6-146257-3, 6-146261-3) or Samtec Flex Stack HMTSW series (HMTSW-113-07-G-D-205, HMTSW-113-07-L-D-210). These parts carry active product status and meet current regulatory requirements. The TE Connectivity 6-146256-3 and 6-146257-3 provide gold mating contact finish matching the original 67997-626 specification. The Samtec HMTSW-113-07-G-D-205 maintains phosphor bronze contact material identical to the original part.

For legacy system maintenance and retrofit applications, the 3M 2326-6121TB and Preci-Dip 450 series (450-10-226-00-013101, 450-80-226-00-001101, 450-80-226-00-013101) remain viable alternatives. These parts are actively manufactured and maintain the 26-position, 2.54mm pitch configuration. The Preci-Dip 450-10-226-00-013101 offers gold mating finish and gold post finish, providing closest electrical and mechanical alignment to the original specification.

Temperature range consideration: The original 67997-626 operates from -65°C to 130°C. The TE Connectivity AMPMODU Mod II series and 3M 2300 series operate to -65°C and -55°C respectively, with upper limits of 105°C. The Preci-Dip 450 series and Samtec HMTSW series extend to 125°C. Applications requiring the full -65°C to 130°C range should evaluate thermal performance requirements against the reduced upper temperature limit of substitute options.

Frequently Asked Questions (FAQ)

Q: Can the 67997-626 be directly replaced with any of these substitute parts?

A: Direct mechanical and electrical replacement is possible for all listed substitutes, provided the application does not require the full -65°C to 130°C operating range of the original part. All substitutes maintain the 26-position, 2-row, 0.100" (2.54mm) pitch configuration, 3A current rating, through-hole solder termination, and push-pull fastening. Verify contact finish requirements (gold vs. tin) and post finish specifications against your mating connector design.

Q: What is the difference between the TE Connectivity 6-146254-3, 6-146256-3, 6-146257-3, and 6-146261-3?

A: All four parts are AMPMODU Mod II series headers with identical mechanical configuration. The primary differences are contact finish specifications: 6-146254-3 features tin mating finish; 6-146256-3 and 6-146257-3 feature gold mating finish with varying thickness (15.0µin and 30.0µin respectively); 6-146261-3 features gold mating finish with 30.0µin thickness and shorter post length (0.090" vs. 0.120"). Select based on mating connector contact finish and required post length for your PCB stack-up.

Q: Are the Preci-Dip 450 series parts interchangeable with each other?

A: The Preci-Dip 450-10-226-00-013101 and 450-80-226-00-013101 share identical contact length specifications (0.134" mating, 0.121" post) but differ in contact finish: 450-10 provides gold mating and post finish, while 450-80 provides tin finish on both. The 450-80-226-00-001101 differs in contact length (0.156" mating, 0.164" post) and is suitable only where these longer dimensions are compatible with your PCB design. Verify contact finish and length requirements before selection.

Q: What is the significance of the Samtec HMTSW series contact finish thickness specifications?

A: The HMTSW-113-07-G-D-205 specifies 10.0µin (0.25µm) gold mating finish with 3.00µin (0.076µm) gold post finish. The HMTSW-113-07-L-D-210 specifies 10.0µin (0.25µm) gold mating finish with tin post finish. These thinner gold specifications reduce material cost while maintaining electrical performance for standard applications. Applications requiring enhanced wear resistance or extended mating cycle life should specify thicker gold finishes available in the TE Connectivity or Preci-Dip alternatives.

Q: Which substitute part most closely matches the original 67997-626 specification?

A: The Samtec HMTSW-113-07-G-D-205 provides the closest match: phosphor bronze contact material (identical to original), gold mating finish, 3A current rating, UL94 V-0 flammability rating, and operating temperature range of -55°C to 125°C. The primary limitation is the reduced lower temperature limit (-55°C vs. -65°C). For applications not requiring the full -65°C lower limit, this part is the preferred substitute.

Q: Are there packaging or inventory considerations for these substitute parts?

A: All listed substitute parts are actively manufactured and maintain current inventory levels ranging from 637 to 1578 pieces. The original 67997-626 carries 1162 pieces in stock but is obsolete. Preci-Dip 450 series parts are supplied in bulk packaging, while TE Connectivity AMPMODU Mod II and Samtec HMTSW series are supplied in bulk packaging. Verify packaging format compatibility with your procurement and assembly processes.
