Substitute Part Grouping Explanation

Substitution for the 68457-336 is determined by strict equivalence across the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (36)
Pitch specification (0.100" / 2.54mm)
Mounting method (Through Hole)
Termination type (Solder)
Board-to-board style compatibility
Unshrouded configuration
Square contact shape
UL94 V-0 flammability rating

The identified substitute parts maintain these core electrical and mechanical characteristics. Variations in contact length, contact finish thickness, current rating, voltage rating, and operating temperature ranges are secondary parameters that do not prevent functional substitution when the primary criteria are met. All substitute parts are active products with current manufacturing status, providing improved availability compared to the obsolete main part.

Engineering Selection Recommendations

Amphenol ICC 68004-336HLF is the primary substitute within the same manufacturer family. This part maintains BERGSTIK® II series compatibility with active product status, RoHS compliance, and specified electrical ratings (5A at 110V). Contact post length differs minimally (0.107" vs. 0.130"), presenting negligible impact on board-level integration.

Amphenol ICC 68771-336HLF offers extended operating temperature range (-65°C to 125°C) with active status and RoHS compliance. Contact post length is shorter (0.100"), requiring verification against PCB pad depth specifications. This variant is suitable for applications requiring wider temperature performance.

TE Connectivity 8-146274-6 (AMPMODU Mod II series) provides cross-manufacturer substitution with active status and RoHS compliance. Insulation height is reduced to 0.090" (2.29mm), and contact finish is tin rather than gold. This part supports breakaway configuration and operates across -65°C to 105°C.

3M 2336-6211-TG (2300 series) offers active status with operating temperature range -55°C to 105°C. Contact finish thickness is reduced (10.0µin), and post finish is tin-lead. This part supports both board-to-board and cable configurations.

3M 929705-06-36-I (929 series) features extended contact post length (0.710"), suitable for applications requiring deeper board penetration or stacking configurations. Operating temperature range is -40°C to 105°C with active status and RoHS compliance.

For new designs, prioritize active products with RoHS compliance. For legacy system maintenance, 68004-336HLF provides the closest electrical and mechanical equivalence within the Amphenol ICC product line.

Frequently Asked Questions (FAQ)

Q: Can I substitute the obsolete 68457-336 with any of these parts directly?

A: Yes, all listed parts maintain the critical functional parameters: 36-position, 2.54mm pitch, through-hole solder termination, unshrouded male pin headers. Physical board-level integration requires verification of contact post length and insulation height against your PCB design specifications.

Q: What is the primary difference between the Amphenol ICC substitutes (68004-336HLF and 68771-336HLF)?

A: Both are BERGSTIK® II series with active status. The 68004-336HLF provides specified electrical ratings (5A/110V) with contact post length of 0.107". The 68771-336HLF extends operating temperature to -65°C to 125°C with shorter contact post (0.100") and 3A current rating.

Q: Why does the 3M 929705-06-36-I have a significantly longer contact post (0.710")?

A: The extended post length accommodates applications requiring deeper board penetration, stacking configurations, or extended mating depth. This part is functionally equivalent for standard board-to-board applications but requires PCB design verification.

Q: Are there RoHS compliance differences I should consider?

A: The main part (68457-336) is RoHS non-compliant. All active substitutes (68004-336HLF, 68771-336HLF, 8-146274-6, 929705-06-36-I) are RoHS compliant. The 3M 2336-6211-TG RoHS status is not specified. For regulated applications, confirm compliance requirements with your procurement standards.

Q: What is the impact of contact finish differences (gold vs. tin)?

A: Gold-finished contacts (68457-336, 68004-336HLF, 68771-336HLF, 2336-6211-TG, 929705-06-36-I) provide superior corrosion resistance and lower contact resistance. The TE Connectivity 8-146274-6 uses tin finish, which is acceptable for standard applications but may require environmental protection consideration in corrosive environments.

Q: Can I use the TE Connectivity 8-146274-6 as a direct replacement?

A: Yes, with design verification. The insulation height is reduced to 0.090" (2.29mm) compared to 0.100" on the main part. Confirm this dimension against your PCB layout and mating connector specifications before implementation.

Q: Which substitute offers the widest operating temperature range?

A: The Amphenol ICC 68771-336HLF operates from -65°C to 125°C, providing the widest temperature specification among all substitutes. This makes it suitable for industrial and automotive applications with extended temperature requirements.
