Amphenol ICC 68629-436 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68629-436 is a rectangular connector header designed for through-hole mounting applications. This 36-position, single-row connector operates at a 0.100" (2.54mm) pitch and features male pins with tin-plated phosphor bronze contacts. The connector is classified as active product status and serves board-to-board interconnection requirements in electronic assemblies. Substitute parts are identified to address inventory availability, compliance requirements, or specific application constraints while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68629-436 is determined by the following critical parameters: connector type (header), contact type (male pin), mating pitch (0.100" / 2.54mm), position count (36), row configuration (1 row), mounting method (through hole), termination type (solder), contact shape (square), and fastening mechanism (push-pull). All identified substitutes maintain these core specifications, ensuring mechanical and electrical compatibility at the board interface level.

The substitute parts listed—TE Connectivity AMP Connectors 8-146274-6 and 3M 929705-06-36-I—satisfy these substitution criteria. Variations in contact material, contact finish composition, insulation material, and post length do not preclude functional substitution when the mating interface parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The 68629-436 is an active product with UL94 V-0 flammability certification and unlimited moisture sensitivity rating. Both substitute parts maintain these certifications and active product status.

The TE Connectivity 8-146274-6 achieves RoHS compliance, whereas the original 68629-436 does not. This substitute is suitable for applications requiring regulatory compliance with lead-free manufacturing standards. The 8-146274-6 operates across -65°C to 105°C and carries a 3A current rating.

The 3M 929705-06-36-I also achieves RoHS compliance and operates across -40°C to 105°C with a 2.5A current rating. This part features gold-plated mating contacts, which may be selected for applications requiring enhanced corrosion resistance or contact reliability in specific environmental conditions.

Selection between substitutes should be based on compliance requirements, operating temperature range, current capacity, and contact finish specifications appropriate to the end application.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the 68629-436?

A: Substitution is determined by matching the core mating interface parameters: 0.100" (2.54mm) pitch, 36-position single-row configuration, male pin contact type, square contact shape, through-hole mounting, solder termination, and push-pull fastening. All listed substitutes meet these criteria.

Q: Are there differences in contact finish between the main part and substitutes?

A: Yes. The 68629-436 features tin-plated contacts. The TE Connectivity 8-146274-6 also uses tin plating. The 3M 929705-06-36-I uses gold plating on both mating and post contacts. Gold plating may provide enhanced corrosion resistance in specific environments but does not affect mechanical compatibility.

Q: What is the significance of RoHS compliance in these parts?

A: The 68629-436 is RoHS non-compliant. Both substitute parts—8-146274-6 and 929705-06-36-I—are RoHS compliant. RoHS compliance indicates lead-free manufacturing and is required for applications subject to EU Directive 2011/65/EU or equivalent regulations. Selection depends on regulatory requirements of the target application.

Q: Do the substitutes have different operating temperature ranges?

A: Yes. The 68629-436 does not specify an operating temperature range. The TE Connectivity 8-146274-6 operates from -65°C to 105°C. The 3M 929705-06-36-I operates from -40°C to 105°C. Applications requiring extended low-temperature operation should specify the TE Connectivity part.

Q: Are there differences in current rating between these parts?

A: Yes. The 68629-436 does not specify a current rating. The TE Connectivity 8-146274-6 is rated for 3A. The 3M 929705-06-36-I is rated for 2.5A. Applications with defined current requirements should select the part with appropriate current capacity.

Q: What is the difference in contact post length between these parts?

A: The 68629-436 has a post length of 0.203" (5.16mm). The TE Connectivity 8-146274-6 has a post length of 0.125" (3.18mm). The 3M 929705-06-36-I has a post length of 0.710" (18.03mm). Post length affects solder joint formation and PCB stack-up considerations. Selection should account for PCB thickness and solder process parameters.

Q: Can these parts be used interchangeably in existing designs?

A: Mechanical and electrical compatibility at the mating interface is maintained across all three parts. However, differences in post length, contact finish, and operating temperature range may require design review. PCB layout, solder process parameters, and thermal management should be evaluated for the specific substitute selected.
