Amphenol ICC 68705-536H Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68705-536H is a rectangular connector header designed for through-hole mounting applications. This BERGSTIK® II series component features 36 vertical positions with 0.100" (2.54mm) pitch spacing, gold-plated mating contacts, and phosphor bronze construction. The connector is classified as Active product status with RoHS non-compliant designation and UL94 V-0 flammability rating. Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: 36-position count, 0.100" pitch, through-hole solder termination, square contact geometry, and board-to-board or cable-compatible style.

Substitute Part Grouping Explanation

Substitute parts for the 68705-536H are qualified based on the following mandatory parameters:

Position Count: 36 positions (exact match required)
Pitch Spacing: 0.100" (2.54mm) mating pitch (exact match required)
Contact Type: Male pin headers
Mounting: Through-hole solder termination
Contact Geometry: Square contact shape
Style Compatibility: Board-to-board or cable-compatible configurations

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and are suitable for direct replacement in applications requiring 36-position, 0.100" pitch through-hole header connectors. The primary differentiation between substitute options is post length, which determines overall connector height and board-to-board spacing requirements.

Sullins Connector Solutions parts (PBC36SAAN, PBC36SABN, PEC36SAAN, PEC36SABN) offer ROHS3 compliance and are available in both gold and tin contact finishes. These parts feature shorter post lengths (0.120" to 0.230") compared to Samtec alternatives, making them suitable for applications with space constraints. Sullins parts with "AA" designation include 0.120" post length; "AB" designation includes 0.230" post length. Contact finish selection between gold (PBC/PEC prefix) and tin (PEC prefix) depends on application requirements.

Samtec TSW series parts (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, TSW-136-22-T-S) provide extended post lengths ranging from 0.300" to 0.600", accommodating applications requiring greater board-to-board separation. Samtec parts are ROHS3 compliant and available in gold-plated (G-S suffix) or tin-plated (T-S suffix) contact finishes. Operating temperature range for gold-plated variants extends to -55°C to 125°C; tin-plated variants operate from -55°C to 105°C.

All substitute parts carry UL94 V-0 flammability certification and maintain phosphor bronze contact material with square contact geometry, ensuring electrical and mechanical compatibility with the original 68705-536H specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute a TSW-136-11-G-S for the 68705-536H in a space-constrained application?

A: The TSW-136-11-G-S features a 0.600" post length, resulting in a 0.930" overall contact length compared to the 68705-536H at 0.395". This extended length requires verification of available board-to-board spacing. For space-constrained designs, Sullins PBC36SAAN or PEC36SAAN with 0.120" post length and 0.450" overall contact length are more suitable.

Q: What is the difference between PBC36SAAN and PEC36SAAN?

A: Both parts share identical mechanical specifications (36 positions, 0.100" pitch, 0.120" post length, 0.450" overall contact length). The primary difference is contact finish: PBC36SAAN features gold-plated mating contacts, while PEC36SAAN features tin-plated mating contacts. Both include tin-plated posts. Selection depends on application corrosion resistance and contact resistance requirements.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are ROHS3 compliant. The original 68705-536H is RoHS non-compliant. If RoHS compliance is a design requirement, any listed substitute part satisfies this requirement.

Q: What post length should I select for my application?

A: Post length determines overall connector height and board-to-board spacing. The 68705-536H uses 0.095" post length. Sullins parts offer 0.120" or 0.230" post lengths for minimal height increase. Samtec parts provide 0.300" to 0.600" post lengths for applications requiring greater separation. Verify PCB layout and mating connector depth before selection.

Q: Can I mix gold and tin contact finishes in the same connector?

A: The listed parts are supplied with uniform contact finish across mating and post surfaces (with minor exceptions noted in specifications). Mixing finishes is not recommended as it may introduce galvanic corrosion at contact interfaces.

Q: What is the operating temperature range for tin-plated variants?

A: Samtec tin-plated variants (TSW-136-09-T-S, TSW-136-10-T-S, TSW-136-22-T-S) operate from -55°C to 105°C. Sullins tin-plated variants (PEC36SAAN, PEC36SABN) operate from -65°C to 125°C. Gold-plated variants from both manufacturers support -55°C to 125°C operation.
