Amphenol ICC 68490-236 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68490-236 is a rectangular connector header for through-hole mounting with 36 positions at 0.100" (2.54mm) pitch. This BERGSTIK® II series component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The connector features unshrouded, board-to-board configuration with solder termination and push-pull fastening. Substitutes must maintain electrical and mechanical compatibility while accommodating modern component availability and compliance requirements.

Substitute Part Grouping Explanation

Substitution for the 68490-236 is determined by strict adherence to the following core parameters:

Connector Type & Configuration: Header, male pin, 36 positions, single row, board-to-board or cable style
Pitch Specification: 0.100" (2.54mm) mating pitch (non-negotiable for mechanical compatibility)
Mounting & Termination: Through-hole solder termination with push-pull fastening
Contact Geometry: Square contact shape with 0.230" (5.84mm) mating contact length
Insulation Height: 0.100" (2.54mm) to maintain PCB footprint compatibility
Material Compliance: UL94 V-0 flammability rating required

Substitute parts are grouped by contact post length, which affects overall connector height and board clearance. Contact finish (gold vs. tin) and insulation material variations are secondary parameters that do not prevent substitution when primary electrical and mechanical criteria are met. Product status transition from obsolete to active components is acceptable for design continuity.

Engineering Selection Recommendations

All listed substitute parts maintain the core electrical and mechanical specifications required for direct replacement of the 68490-236. Selection among substitutes depends on contact post length requirements and compliance objectives.

For RoHS Compliance Transition: All substitute parts are RoHS compliant (RoHS or ROHS3), addressing the non-compliant status of the original 68490-236. This transition is necessary for modern supply chain requirements and regulatory adherence.

For Identical Mating Contact Length: HTSW-136-26-TM-S, PGC36SAAN, TSW-136-07-F-S, TSW-136-09-G-S, TSW-136-09-T-S, TSW-136-10-G-S, TSW-136-10-T-S, TSW-136-11-G-S, and TSW-136-13-F-S all maintain the 0.230" (5.84mm) mating contact length, ensuring consistent mating interface performance.

For Post Length Variations: Contact post length differs across substitutes, ranging from 0.100" to 0.900". Selection must account for PCB thickness, component clearance, and solder joint depth requirements. The 8-146274-6 features the shortest post length at 0.125" (3.18mm), suitable for thin PCB applications. TSW-136-13-F-S provides the longest post at 0.900" (22.86mm) for applications requiring extended solder joint engagement.

For Temperature Operating Range: TSW series parts (TSW-136-07-F-S through TSW-136-13-F-S) and HTSW-136-26-TM-S support -55°C to 125°C or -55°C to 105°C operating ranges, exceeding the original part's unspecified temperature rating. PGC36SAAN and 8-146274-6 provide -65°C to 105°C and 3A current rating respectively.

For Active Product Status: All substitutes are classified as active products with current manufacturing support, ensuring long-term availability and supply chain stability compared to the obsolete 68490-236.

Frequently Asked Questions (FAQ)

Q: Can the 68490-236 be directly replaced with any of these substitutes without PCB modification?

A: Direct replacement depends on contact post length. Substitutes with identical or longer post lengths (0.230" mating contact length maintained across all options) are mechanically compatible with existing PCB footprints. However, post length variations (ranging from 0.100" to 0.900") may require solder joint depth adjustment. Verify PCB hole depth and clearance specifications before selection.

Q: What is the primary reason for substitution?

A: The 68490-236 is classified as obsolete. All listed substitutes are active products with current manufacturing support. Additionally, the original part is RoHS non-compliant, while all substitutes meet RoHS or ROHS3 compliance requirements.

Q: Are there electrical performance differences between gold and tin contact finishes?

A: Contact finish (gold vs. tin) does not affect electrical compatibility. Both finishes maintain the required contact resistance and signal integrity for this connector category. Selection between gold-plated (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S, TSW-136-13-F-S, PGC36SAAN) and tin-plated (TSW-136-09-T-S, TSW-136-10-T-S, 8-146274-6, HTSW-136-26-TM-S) options is based on application environment and cost considerations.

Q: Does insulation material affect substitution compatibility?

A: Insulation material variations (Polybutylene Terephthalate, Liquid Crystal Polymer, Thermoplastic Polyester) do not prevent substitution. All materials meet UL94 V-0 flammability requirements. Material selection impacts mechanical durability and temperature performance but does not affect electrical compatibility or PCB footprint.

Q: Which substitute offers the best compatibility for existing designs?

A: HTSW-136-26-TM-S and PGC36SAAN provide closest dimensional alignment with the original 68490-236, maintaining 0.230" mating contact length and 0.100" insulation height. Both are active products with RoHS compliance. HTSW-136-26-TM-S offers -55°C to 105°C operating range, while PGC36SAAN provides 3A current rating specification.

Q: What post length should be selected for new designs?

A: Post length selection depends on PCB thickness and solder joint requirements. Standard PCB applications (1.6mm thickness) typically use TSW-136-09-G-S or TSW-136-09-T-S (0.400" post). Thicker PCBs or applications requiring deeper solder engagement benefit from TSW-136-10-G-S, TSW-136-10-T-S (0.500" post), or TSW-136-11-G-S (0.600" post). Thin PCB applications may use 8-146274-6 (0.125" post) or TSW-136-07-F-S (0.100" post).

Q: Are all substitutes available in bulk packaging?

A: Most substitutes are available in bulk packaging. 8-146274-6, PGC36SAAN, TSW-136-07-F-S, TSW-136-09-G-S, TSW-136-09-T-S, TSW-136-10-G-S, TSW-136-10-T-S, TSW-136-11-G-S, and TSW-136-13-F-S are confirmed bulk packaged. HTSW-136-26-TM-S packaging specification is not provided; verify with supplier for bulk availability.
