Amphenol ICC 68653-136H Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68653-136H is an active rectangular connector header designed for through-hole board-to-board applications. This 36-position, single-row header operates at a 0.100" (2.54mm) pitch and features unshrouded male pin contacts with solder termination. The connector is part of the BERGSTIK® II series and maintains UL94 V-0 material flammability rating with gold-plated mating contacts. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 68653-136H is determined by the following critical parameters:

Connector type (Header), contact type (Male Pin), number of positions (36), number of rows (1), pitch (0.100"/2.54mm), mounting type (Through Hole), termination method (Solder), shrouding (Unshrouded), contact shape (Square), and insulation height (0.100"/2.54mm) must remain constant across substitute parts.

The Samtec TSW-136-15-G-S meets all these core requirements. While minor variations exist in contact length specifications and contact finish thickness, these differences fall within acceptable tolerances for board-to-board header applications and do not affect mechanical or electrical compatibility in standard PCB mounting scenarios.

Engineering Selection Recommendations

Both the Amphenol ICC 68653-136H and Samtec TSW-136-15-G-S are active products with UL94 V-0 material flammability certification. The primary distinction is RoHS compliance status: the Samtec TSW-136-15-G-S is ROHS3 compliant, while the Amphenol ICC 68653-136H is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. The Samtec part provides documented operating temperature range (-55°C ~ 125°C), whereas the Amphenol part does not specify this parameter. Contact length variations between the two parts are minimal and do not affect standard PCB mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TSW-136-15-G-S directly replace the Amphenol ICC 68653-136H in existing designs?

A: Yes, from a mechanical and electrical standpoint. Both connectors share identical pitch (0.100"/2.54mm), position count (36), row configuration (1), contact type (Male Pin), and mounting method (Through Hole Solder). Contact length differences are within typical tolerance ranges for board-to-board header applications.

Q: What is the significance of the RoHS compliance difference?

A: The Samtec TSW-136-15-G-S is ROHS3 compliant, while the Amphenol ICC 68653-136H is RoHS non-compliant. RoHS compliance is a regulatory requirement in certain markets and applications. Selection depends on whether your application or end market mandates RoHS compliance.

Q: Are there differences in contact finish that affect performance?

A: Both parts feature gold-plated mating contacts on phosphor bronze base material. The Amphenol part specifies 30.0µin (0.76µm) finish thickness, while the Samtec part specifies 10.0µin (0.25µm). Both thicknesses provide adequate corrosion resistance and electrical conductivity for standard applications.

Q: Does the operating temperature specification affect substitution eligibility?

A: The Samtec part provides an operating temperature range of -55°C ~ 125°C. The Amphenol part does not specify this parameter in the provided data. If your application requires documented temperature performance, the Samtec part offers explicit specification. Absence of specification in the Amphenol data does not indicate temperature limitations.

Q: Are the contact length variations significant?

A: Contact length differences are minimal (0.015" mating contact difference, 0.020" post length difference). These variations fall within standard tolerance ranges for through-hole solder termination and do not affect PCB mounting compatibility or electrical performance in typical board-to-board applications.
