Amphenol ICC 68604-236 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68604-236 is a rectangular connector header with 36 vertical positions at 2.54mm pitch, designed for through-hole board-to-board applications. This component is classified as obsolete, necessitating identification of active equivalent parts that maintain functional compatibility.

Engineering Selection Recommendations

Primary Substitute: PEC36SFAN (Sullins Connector Solutions)

The PEC36SFAN is the optimal substitute for the obsolete 68604-236. This part maintains full electrical and mechanical compatibility across all critical parameters: 36-position, 2.54mm pitch, through-hole solder termination, and -65°C to 125°C operating range. The PEC36SFAN carries ROHS3 compliance and active product status, ensuring long-term availability and regulatory alignment. Contact post length of 0.120" (3.05mm) matches the original specification exactly, minimizing PCB redesign requirements.

Secondary Substitute: PBC36SFAN (Sullins Connector Solutions)

The PBC36SFAN provides equivalent functionality with identical contact post length (0.120") and operating temperature range (-65°C to 125°C). This part is suitable for applications where gold mating contact finish is preferred over tin. ROHS3 compliance and high inventory availability (4272 units) support production continuity.

Alternative Substitute: 929705-06-36-I (3M)

The 929705-06-36-I from 3M meets core substitution criteria but exhibits two parameter deviations: reduced operating temperature range (-40°C to 105°C) and lower current rating (2.5A versus 3A). This part is suitable only for applications operating within the narrower temperature and current specifications. Extended contact post length (0.710") requires PCB layout verification.

Not Recommended: PEC36SFCN (Sullins Connector Solutions)

While the PEC36SFCN maintains full electrical compatibility, the extended contact post length (0.320" versus 0.120") introduces significant mechanical differences requiring PCB redesign. This part is suitable only when extended post length is a design requirement.

Frequently Asked Questions (FAQ)

Q: Can the 929705-06-36-I substitute for the 68604-236 in all applications?

A: No. The 929705-06-36-I operates at -40°C to 105°C, which is narrower than the original -65°C to 125°C range. Additionally, its 2.5A current rating is lower than the original 3A specification. Verify that your application operates within these reduced parameters before selection.

Q: What is the primary difference between PEC36SFAN and PBC36SFAN?

A: Both parts are functionally equivalent with identical contact post length and operating temperature range. The primary difference is contact finish: PEC36SFAN uses tin finish on both mating and post surfaces, while PBC36SFAN uses gold on the mating surface and tin on the post. Select based on your application's contact finish requirements.

Q: Why does PEC36SFCN have a longer contact post?

A: The PEC36SFCN contact post length is 0.320" (8.13mm) compared to 0.120" (3.05mm) on the original part. This extended length is a design variant for applications requiring deeper PCB penetration. Verify PCB thickness compatibility before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts carry RoHS compliance (RoHS Compliant or ROHS3 Compliant status). The original 68604-236 is RoHS non-compliant. Regulatory requirements may mandate selection of compliant substitutes.

Q: What is the difference between "Header" and "Header, Breakaway" connector types?

A: All substitute parts are classified as "Header, Breakaway," indicating the connector can be separated into individual pins if required. The original part is classified as "Header" without breakaway capability. Both types are mechanically and electrically compatible for standard board-to-board applications.

Q: Which substitute has the highest inventory availability?

A: PEC36SFAN has the highest inventory with 6328 units in stock, followed by PBC36SFAN with 4272 units. Both Sullins parts provide superior availability compared to the 3M alternative (1268 units).

Q: Can I use these substitutes interchangeably on the same PCB?

A: PEC36SFAN and PBC36SFAN are directly interchangeable due to identical contact post length (0.120"). The 929705-06-36-I and PEC36SFCN require PCB layout verification due to different contact post lengths. Do not mix different post lengths on the same board without design review.
