Substitute Part Grouping Explanation

Substitution eligibility for the 68457-436 is determined by the following critical parameters:

Pitch - Mating: 0.100" (2.54mm) - must match exactly for mechanical compatibility
Number of Positions: 36 positions - determines connector footprint and pin count
Connector Type: Header with male pins - defines mating interface
Mounting Type: Through hole - establishes PCB assembly method
Termination: Solder - specifies connection method to PCB
Fastening Type: Push-pull - defines mechanical engagement mechanism
Contact Shape: Square - ensures proper mating with corresponding receptacles

Substitute parts are grouped into two categories:

Category A - Direct 36-Position Substitutes: Parts maintaining identical position count (36) with matching pitch, connector type, and mounting specifications. These include 78511-436HLF (Amphenol ICC), 2336-6211-TG (3M), and 929705-06-36-I (3M).

Category B - Functional Alternative: Part 8-146274-6 (TE Connectivity) provides equivalent electrical and mechanical function with 36 positions but differs in insulation material and contact post length specifications.

Category C - Position Variance: Part 9-146274-0 (TE Connectivity) contains 40 positions instead of 36, making it unsuitable for direct substitution in applications requiring exactly 36 positions.

Engineering Selection Recommendations

Primary Substitute - 78511-436HLF (Amphenol ICC)

The 78511-436HLF is the recommended direct substitute for the obsolete 68457-436. Both parts are from Amphenol ICC and share identical mechanical specifications including 36 positions, 2.54mm pitch, and through-hole solder termination. The 78511-436HLF is active in production with superior compliance status (RoHS Compliant vs. RoHS non-compliant), extended operating temperature range (-65°C to 125°C), and higher current rating (5A). This part provides the most seamless transition for existing designs.

Secondary Substitute - 2336-6211-TG (3M)

The 2336-6211-TG from 3M's 2300 series maintains the critical 36-position, 2.54mm pitch configuration with identical contact mating length. This part is active and RoHS compliant. The primary distinction is the gold-plated mating contact finish compared to tin on the original part, which may provide enhanced corrosion resistance in certain environments. Operating temperature range is -55°C to 105°C with 3A current rating.

Tertiary Substitute - 929705-06-36-I (3M)

The 929705-06-36-I from 3M's 929 series provides 36-position compatibility with 2.54mm pitch and is RoHS compliant. This part features extended post length (0.710" vs. 0.130" on the original), making it suitable for applications requiring deeper PCB penetration or stacking configurations. Gold-plated contacts provide enhanced durability. Operating temperature range is -40°C to 105°C with 2.5A current rating.

Functional Alternative - 8-146274-6 (TE Connectivity)

The 8-146274-6 from TE Connectivity's AMPMODU Mod II series maintains 36-position, 2.54mm pitch specifications with breakaway capability. This part is RoHS compliant and active. The insulation material differs (Liquid Crystal Polymer vs. unspecified on original), and insulation height is slightly reduced (0.090" vs. 0.100"). Operating temperature range is -65°C to 105°C with 3A current rating.

Not Recommended - 9-146274-0 (TE Connectivity)

The 9-146274-0 contains 40 positions instead of 36, making it unsuitable for direct substitution in applications requiring exactly 36 positions. This part should only be considered if design modifications to accommodate additional positions are feasible.

Frequently Asked Questions (FAQ)

Q: Can I use the 78511-436HLF as a direct replacement for the 68457-436?

A: Yes. The 78511-436HLF is the recommended direct substitute. Both parts share identical pitch (2.54mm), position count (36), connector type (header), contact type (male pin), mounting method (through hole), and termination (solder). The 78511-436HLF is active in production and offers improved compliance and performance specifications.

Q: What is the primary difference between the 68457-436 and its substitutes?

A: The main difference is product status. The 68457-436 is obsolete, while all recommended substitutes are active. Additionally, the original part is RoHS non-compliant, whereas active substitutes are RoHS compliant. Mechanical and electrical specifications remain compatible across the primary substitute options.

Q: Why does the 929705-06-36-I have a much longer post length (0.710" vs. 0.130")?

A: The extended post length on the 929705-06-36-I is designed for applications requiring deeper PCB penetration or connector stacking. This part is suitable for designs where standard post lengths are insufficient. Verify PCB thickness and assembly requirements before selecting this variant.

Q: Can I use the 2336-6211-TG with its gold-plated contacts instead of tin-plated alternatives?

A: Yes. Gold plating provides enhanced corrosion resistance and is compatible with standard solder assembly processes. The gold finish on the 2336-6211-TG mating contacts is a functional upgrade that does not compromise compatibility with standard receptacles designed for 2.54mm pitch headers.

Q: Why is the 9-146274-0 listed if it has 40 positions instead of 36?

A: The 9-146274-0 is included for reference only. It is not a direct substitute due to the position count difference. This part should only be considered if your application can accommodate 40 positions or if design modifications are acceptable.

Q: What packaging options are available for these substitutes?

A: The 78511-436HLF is supplied in bag packaging. The 8-146274-6, 2336-6211-TG, 929705-06-36-I, and 9-146274-0 are supplied in bulk packaging. Verify packaging requirements with your procurement process before finalizing part selection.

Q: Are all substitute parts suitable for high-temperature applications?

A: The 78511-436HLF offers the widest operating temperature range (-65°C to 125°C). The 8-146274-6 and 9-146274-0 support -65°C to 105°C. The 2336-6211-TG supports -55°C to 105°C, and the 929705-06-36-I supports -40°C to 105°C. Select based on your specific temperature requirements.

Q: What current ratings should I consider when selecting a substitute?

A: The 78511-436HLF supports 5A, while the 8-146274-6, 2336-6211-TG, and 9-146274-0 support 3A. The 929705-06-36-I supports 2.5A. Verify your application's current requirements and select accordingly. The original 68457-436 does not specify a current rating.
