Amphenol ICC 68656-136 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68656-136 is a rectangular connector header featuring 36 vertical positions with 0.100" (2.54mm) pitch spacing. This through-hole component is part of the BERGSTIK® II series and serves as a board-to-board interface connector with solder termination and push-pull fastening. The part maintains active product status with 829 units in current inventory. Substitute parts are identified based on matching core electrical and mechanical parameters: 36-position configuration, 2.54mm pitch, through-hole mounting, solder termination, and board-to-board connectivity.

Substitute Part Grouping Explanation

Substitution eligibility for the 68656-136 is determined by strict alignment with the following core parameters:

36-position connector configuration
0.100" (2.54mm) mating pitch
Single-row layout
Through-hole solder termination
Push-pull fastening mechanism
Unshrouded header design
Square contact geometry
UL94 V-0 flammability rating
Black insulation color
Board-to-board or board-to-cable interface capability

All four identified substitute parts meet these mandatory criteria. Variations in contact length, contact finish composition, and operating temperature ranges do not disqualify substitution when core mechanical and electrical parameters align.

Engineering Selection Recommendations

All four substitute parts maintain active product status and meet the core mechanical and electrical requirements for direct substitution with the 68656-136.

The 929705-06-36-I (3M) offers RoHS compliance and operates across -40°C to 105°C with a 2.5A current rating. This part is suitable for applications requiring regulatory compliance within the specified temperature range.

The PBC36SFAN, PEC36SFAN, and PEC36SFCN (Sullins Connector Solutions) all provide ROHS3 compliance and extended operating temperature range of -65°C to 125°C with 3A current rating. These parts support both board-to-board and board-to-cable configurations. The primary distinction among the three Sullins options lies in contact post length and contact finish composition:

PBC36SFAN: Gold mating finish, 0.120" post length
PEC36SFAN: Tin mating finish, 0.120" post length
PEC36SFCN: Tin mating finish, 0.320" post length

Selection between these options depends on application-specific requirements for contact finish material and post length compatibility with mating receptacles. The 68656-136 exhibits RoHS non-compliance; applications requiring regulatory compliance should prioritize the RoHS-compliant substitute options.

Frequently Asked Questions (FAQ)

Q: Can the 929705-06-36-I replace the 68656-136 in all applications?

A: The 929705-06-36-I meets all core mechanical and electrical parameters for substitution. However, the operating temperature range differs (-40°C to 105°C versus unspecified for the 68656-136). Verify that your application temperature requirements fall within the 929705-06-36-I specification before implementation.

Q: What is the difference between the three Sullins substitute parts?

A: All three Sullins parts (PBC36SFAN, PEC36SFAN, PEC36SFCN) share identical core specifications: 36 positions, 2.54mm pitch, through-hole solder termination, and push-pull fastening. Differences exist in contact post length (0.120" for PBC36SFAN and PEC36SFAN; 0.320" for PEC36SFCN) and mating contact finish (gold for PBC36SFAN; tin for PEC36SFAN and PEC36SFCN). Select based on your mating receptacle requirements and PCB stack-up depth.

Q: Does contact finish affect substitution compatibility?

A: Contact finish (gold versus tin) does not prevent mechanical or electrical substitution. However, contact finish selection may influence long-term reliability in specific environmental conditions. Verify that your mating receptacle contact material is compatible with the selected substitute's contact finish.

Q: Are all substitute parts available in equivalent quantities?

A: Inventory levels vary. PEC36SFAN maintains the highest inventory (6328 units), followed by PBC36SFAN (4272 units), 929705-06-36-I (1268 units), and PEC36SFCN (1391 units). The original 68656-136 has 829 units in stock.

Q: What does "breakaway" connector type mean?

A: Breakaway indicates that individual positions can be separated from the main connector body. This feature provides design flexibility for applications requiring partial connector configurations. The 68656-136 does not specify breakaway capability, while all substitute parts include this feature.

Q: Is the 68656-136 suitable for new designs?

A: The 68656-136 maintains active product status. However, given that all substitute parts offer RoHS compliance (which the 68656-136 does not), new designs should consider RoHS-compliant alternatives to meet current regulatory requirements.
