Amphenol ICC 78229-136 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78229-136 is a vertical through-hole rectangular connector header with 36 positions at 0.100" (2.54mm) pitch, part of the BERGSTIK® II series. This connector is designed for board-to-board applications with press-fit and solder termination options. The part is currently active in production with 886 units in stock.

Substitute parts become necessary when the original part is unavailable, when alternative compliance certifications are required, or when design specifications allow for compatible alternatives that meet the same electrical and mechanical interface requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 78229-136 is determined by strict alignment with the following critical parameters:

Mating pitch: 0.100" (2.54mm) — exact match required
Number of positions: 36 — exact match required
Number of rows: 1 — exact match required
Contact type: Male pin — exact match required
Mounting type: Through hole — exact match required
Contact mating length: 0.318" (8.08mm) — exact match required
Insulation height: 0.100" (2.54mm) — exact match required
Contact shape: Square — exact match required
Flammability rating: UL94 V-0 — exact match required

All four substitute parts (8-146274-6, PBC36SFAN, PEC36SFAN, PEC36SFCN) meet these critical parameters. Variations in contact finish, contact material, insulation material, and post length do not affect mating compatibility when the above parameters are identical.

Engineering Selection Recommendations

All four substitute parts maintain full mating compatibility with the 78229-136 based on identical pitch, position count, row configuration, contact type, and mating dimensions.

TE Connectivity 8-146274-6: This part offers RoHS compliance and is recommended for applications requiring regulatory adherence to RoHS directives. The insulation height of 0.090" (2.29mm) represents a minor deviation from the 0.100" specification; this difference does not affect mating compatibility but should be evaluated for board layout clearance. Operating temperature range extends to 105°C.

Sullins PBC36SFAN: This part provides ROHS3 compliance with gold mating contact finish, matching the original part's contact finish specification. Phosphor bronze contact material and PBT insulation material align with the 78229-136 design. Operating temperature range extends to 125°C. Contact post length matches the original specification exactly.

Sullins PEC36SFAN: This part provides ROHS3 compliance with tin mating contact finish and phosphor bronze contact material. PBT insulation material and contact dimensions match the original specification. Operating temperature range extends to 125°C. This part offers the highest inventory availability at 6328 units.

Sullins PEC36SFCN: This part provides ROHS3 compliance with tin mating contact finish and phosphor bronze contact material. The contact post length is 0.320" (8.13mm), significantly longer than the original 0.120" (3.05mm) specification. This extended post length is suitable for applications requiring deeper board penetration or extended solder joint engagement. Operating temperature range extends to 125°C.

Frequently Asked Questions (FAQ)

Q: Can I use these substitute parts interchangeably with the 78229-136?

A: Yes, all four substitute parts maintain identical mating pitch (0.100"), position count (36), row configuration (1), contact type (male pin), and mating contact length (0.318"). These parameters define mating compatibility. Differences in contact finish, insulation material, and post length do not affect the ability to mate with a compatible receptacle.

Q: What is the significance of the contact post length variation in PEC36SFCN?

A: The PEC36SFCN features a contact post length of 0.320" (8.13mm) compared to 0.120" (3.05mm) in the original part. This extended post provides greater solder joint engagement on the PCB and is suitable for applications requiring enhanced mechanical strength or deeper board penetration. Board layout and solder pad design must accommodate this longer post.

Q: Why does the 8-146274-6 have a different insulation height?

A: The 8-146274-6 specifies an insulation height of 0.090" (2.29mm) versus 0.100" (2.54mm) in the original part. This 0.010" (0.25mm) difference does not affect mating compatibility but may impact board-level clearance calculations. Verify that PCB layout accommodates this dimension before selection.

Q: What is the difference between RoHS and ROHS3 compliance?

A: RoHS compliance restricts hazardous substances in electrical and electronic equipment. ROHS3 represents the third iteration of the RoHS directive with updated substance restrictions. The original 78229-136 is RoHS non-compliant. All substitute parts are RoHS or ROHS3 compliant, making them suitable for applications subject to RoHS regulatory requirements.

Q: How do contact finish differences affect performance?

A: Contact finish (gold, tin, or gold with GXT™) affects corrosion resistance, contact resistance, and wear characteristics. Gold finishes provide superior corrosion resistance and lower contact resistance but increase cost. Tin finishes are cost-effective and suitable for standard applications. Selection depends on environmental conditions and electrical performance requirements specified in the application design.

Q: Which substitute part should I select for maximum inventory availability?

A: The Sullins PEC36SFAN offers the highest inventory at 6328 units. This part provides ROHS3 compliance, tin mating contact finish, phosphor bronze contact material, and standard contact post length matching the original specification.

Q: Are there any temperature rating considerations?

A: The original 78229-136 does not specify an operating temperature range. All substitute parts specify -65°C to 105°C or -65°C to 125°C operating ranges. For applications requiring operation above 105°C, select PBC36SFAN, PEC36SFAN, or PEC36SFCN, which all support -65°C to 125°C.
