Amphenol ICC 68629-536 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68629-536 is a vertical through-hole rectangular connector header with 36 positions at 2.54mm pitch, part of the BERGSTIK® II series. This connector is designed for board-to-board applications requiring reliable solder termination and push-pull fastening. The part maintains active product status with 934 units in current inventory. Substitute parts are identified to address availability, compliance requirements, or specific application constraints while maintaining functional compatibility within the 36-position 2.54mm pitch connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68629-536 is determined by strict alignment with the following core parameters: 36-position count, 2.54mm mating pitch, male pin contact type, through-hole mounting, solder termination, push-pull fastening, square contact shape, unshrouded configuration, and UL94 V-0 flammability rating. All identified substitutes meet these mandatory criteria. Variations in contact finish (gold versus tin), contact material composition (phosphor bronze versus copper alloy), insulation material (unspecified versus LCP or PBT), post length, and operating temperature ranges are permitted within the substitute group, as these parameters do not affect the core mating interface or board-level compatibility. RoHS compliance status and contact finish thickness may differ between the main part and substitutes based on manufacturing and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 8-146274-6: This substitute is recommended for applications requiring RoHS compliance and reduced post length. The 0.125" post length accommodates standard PCB thicknesses and provides compact board-level integration. Tin contact finish meets industrial soldering standards. Operating temperature range of -65°C to 105°C supports extended environmental conditions. Current rating of 3A exceeds typical header applications. Active product status ensures supply continuity.

3M 929705-06-36-I: This substitute is suitable for applications where extended post length (0.710") is required for through-hole mounting into thicker substrates or when additional mechanical standoff is necessary. Gold contact finish provides enhanced corrosion resistance. RoHS compliance and REACH unaffected status support regulatory requirements. Operating temperature range of -40°C to 105°C covers standard industrial applications. Current rating of 2.5A is appropriate for standard signal distribution. Active product status ensures availability.

Both substitutes maintain full functional compatibility with the 68629-536 at the mating interface. Selection between substitutes depends on post length requirements, RoHS compliance mandates, and operating temperature specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 8-146274-6 directly replace the Amphenol ICC 68629-536 on existing PCBs?

A: Direct replacement is possible if the PCB is designed for standard post length tolerance. The TE Connectivity part features a shorter post length (0.125" versus 0.203"), which may require PCB via depth adjustment. Verify PCB hole depth and solder pad design before substitution.

Q: What is the primary difference between the 3M 929705-06-36-I and the other two parts?

A: The 3M part has a significantly longer post length (0.710" versus 0.203" and 0.125"), making it suitable for applications requiring extended mechanical standoff or mounting into thicker substrates. This difference affects PCB design and assembly procedures.

Q: Are all three parts compatible with the same mating connectors?

A: Yes. All three parts share identical mating pitch (2.54mm), contact type (male pin), contact shape (square), and mating contact length (0.318"). They are compatible with standard 2.54mm pitch female connectors and sockets.

Q: Which substitute should be selected for new designs?

A: For new designs, the TE Connectivity 8-146274-6 is recommended due to RoHS compliance, standard post length, and active product status with high inventory availability. The 3M 929705-06-36-I is selected only when extended post length is a design requirement.

Q: Does contact finish affect electrical performance?

A: Contact finish (gold, tin, or GXT™) does not affect mating interface electrical performance for standard signal applications. Selection is based on corrosion resistance requirements and soldering process compatibility. Gold finishes provide enhanced corrosion resistance in harsh environments; tin finishes are standard for industrial applications.

Q: What is the impact of insulation height variation between parts?

A: Insulation height variation (0.090" to 0.100") is within standard tolerance for 2.54mm pitch headers and does not affect mating compatibility or board-level integration. This parameter is non-critical for substitution purposes.
