Amphenol ICC 68691-218 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68691-218 is a rectangular connector header featuring 18 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. This through-hole solder-terminated connector is part of the BERGSTIK® II series and is designed for board-to-board applications. The part maintains active product status with 913 units in current inventory.

Substitute parts become necessary when the original manufacturer part is unavailable, when design requirements demand alternative compliance certifications, or when specific contact finish or insulation material specifications must be modified for application compatibility.

Engineering Selection Recommendations

PBC09DFAN and PEC09DFAN are direct functional equivalents to the 68691-218 with identical contact post length (0.120" / 3.05mm) and overall contact length (0.538" / 13.67mm). Both parts are manufactured by Sullins Connector Solutions and maintain active product status. PBC09DFAN features gold mating contact finish, while PEC09DFAN specifies tin mating contact finish. Both achieve ROHS3 compliance, addressing regulatory requirements where the original part does not.

PBC09DFBN provides an alternative with extended contact post length (0.220" / 5.58mm) and overall contact length (0.638" / 16.21mm). This variant accommodates applications requiring deeper PCB penetration or extended solder joint engagement. PBC09DFBN maintains ROHS3 compliance and active product status.

All three substitute parts satisfy the core electrical and mechanical requirements of the 68691-218 application space. Selection between PBC09DFAN, PBC09DFBN, and PEC09DFAN depends on specific contact finish requirements (gold versus tin), post length specifications, and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can PBC09DFAN be used as a direct replacement for 68691-218?

A: Yes. PBC09DFAN matches all critical parameters: 18 positions, 2 rows, 0.100" pitch, through-hole solder termination, square contact shape, and UL94 V-0 flammability rating. Contact post length and overall contact length are identical. The primary difference is manufacturer (Sullins versus Amphenol ICC) and compliance certification (ROHS3 compliant versus RoHS non-compliant).

Q: What is the difference between PBC09DFAN and PBC09DFBN?

A: Both parts are manufactured by Sullins and share identical position count, pitch, and row spacing. The distinction lies in contact post length: PBC09DFAN specifies 0.120" (3.05mm) post length with 0.538" (13.67mm) overall contact length, while PBC09DFBN specifies 0.220" (5.58mm) post length with 0.638" (16.21mm) overall contact length. PBC09DFBN accommodates applications requiring extended solder joint depth.

Q: Why does PEC09DFAN specify tin mating contact finish instead of gold?

A: PEC09DFAN is a valid substitute with tin mating contact finish (100.0µin / 2.54µm thickness) and tin post finish. This specification represents an alternative contact finish option within the Sullins connector portfolio. Selection between gold and tin finish depends on application-specific requirements for corrosion resistance, contact resistance, and environmental exposure.

Q: Are all substitute parts currently in stock?

A: Inventory status at time of reference: PBC09DFAN (1054 units), PBC09DFBN (1393 units), and PEC09DFAN (972 units) are all available as new original stock.

Q: What compliance certifications apply to the substitute parts?

A: PBC09DFAN, PBC09DFBN, and PEC09DFAN all achieve ROHS3 compliance and carry REACH Unaffected status. The original 68691-218 is RoHS non-compliant. Substitute parts are suitable for applications requiring RoHS3 certification.
