Amphenol ICC 68602-226 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68602-226 is a BERGSTIK® II unshrouded header connector for through-hole board-to-board applications. This 26-position, 2-row rectangular connector operates at 3A per contact and maintains performance across -65°C to 130°C. The part is currently active in production. Substitute parts may be required due to inventory constraints, design revisions, or end-of-life considerations for legacy components in the AMPMODU Mod II series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68602-226 is determined by strict alignment of core electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type: Header (with or without breakaway capability)
• Position count: 26 positions
• Row configuration: 2 rows
• Pitch specification: 0.100" (2.54mm) mating pitch and row spacing
• Contact type: Male pin
• Mounting: Through-hole solder termination
• Current capacity: 3A minimum
• Shrouding: Unshrouded
• Flammability: UL94 V-0

Acceptable Variations:

• Contact finish material (Gold, Tin, or Tin-Lead on post)
• Insulation material (Liquid Crystal Polymer or Thermoplastic)
• Operating temperature upper limit (105°C or 130°C)
• Product status (Active or Obsolete)
• Packaging format (Bag or Bulk)

The TE Connectivity AMP Connectors parts 6-146256-3 and 4-103186-0-13 meet all critical parameters and are classified as direct or similar substitutes based on their identical pitch, position count, row configuration, and electrical ratings.

Engineering Selection Recommendations

6-146256-3 (TE Connectivity AMP Connectors) - Direct Substitute

This part is the preferred substitute for the 68602-226. It maintains active product status, meets all critical electrical and mechanical parameters, and carries RoHS3 compliance certification. The 6-146256-3 features breakaway capability, which provides additional design flexibility. The reduced post length (0.120" vs. 0.150") and insulation height (0.090" vs. 0.100") are within acceptable mechanical tolerances for standard through-hole PCB applications. Operating temperature is rated to 105°C, which covers most industrial and commercial applications; designs requiring operation above 105°C must retain the original 68602-226. Inventory availability is higher (1578 pcs vs. 795 pcs).

4-103186-0-13 (TE Connectivity AMP Connectors) - Similar Substitute

This part meets all critical electrical and mechanical parameters but carries obsolete product status and RoHS non-compliant designation. The Tin-Lead post finish (100.0µin) differs from the Tin finish on the 6-146256-3. Use of this part is not recommended for new designs or applications requiring RoHS compliance. It may be considered only for legacy system maintenance where existing inventory exists and no alternative is available.

Frequently Asked Questions (FAQ)

Q: Can the 6-146256-3 be used as a direct replacement for the 68602-226 in all applications?

A: The 6-146256-3 is mechanically and electrically compatible for most applications. However, verify that your PCB design accommodates the reduced post length (0.120" vs. 0.150") and insulation height (0.090" vs. 0.100"). If your application requires operation above 105°C, the 68602-226 must be retained due to its 130°C upper temperature limit.

Q: What is the difference between the 6-146256-3 and 4-103186-0-13?

A: Both parts share identical pitch, position count, and electrical ratings. The primary differences are: (1) 6-146256-3 is active; 4-103186-0-13 is obsolete; (2) 6-146256-3 uses Tin post finish and LCP insulation; 4-103186-0-13 uses Tin-Lead post finish and Thermoplastic insulation; (3) 6-146256-3 is RoHS3 compliant; 4-103186-0-13 is RoHS non-compliant. The 6-146256-3 is the recommended choice.

Q: Are there any mechanical compatibility issues when substituting the 68602-226 with the 6-146256-3?

A: The contact mating length (0.230") is identical, ensuring proper mating depth. The post length difference (0.150" vs. 0.120") and insulation height difference (0.100" vs. 0.090") may affect solder joint geometry and PCB clearance. Verify your PCB design accommodates these dimensional variations before implementation.

Q: Does the breakaway feature on the 6-146256-3 affect compatibility?

A: The breakaway feature is an additional capability that does not compromise compatibility. It allows individual positions to be separated if required by your application. Standard non-breakaway use is fully supported.

Q: What is the significance of the contact finish differences?

A: All three parts use Gold mating contact finish at 15.0µin thickness, ensuring equivalent mating performance. Post finish (Tin vs. Tin-Lead) affects solder joint formation and long-term reliability. Tin finish (6-146256-3) is preferred for RoHS-compliant applications. Tin-Lead finish (4-103186-0-13) is obsolete and not recommended for new designs.

Q: Can I mix the 68602-226 and 6-146256-3 in the same assembly?

A: Yes. Both parts are mechanically and electrically compatible and can coexist in the same assembly. However, standardizing on a single part number is recommended for manufacturing consistency and inventory management.
