Amphenol ICC 68603-436 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68603-436 is a rectangular connector header for through-hole mounting, featuring 36 positions at 0.100" (2.54mm) pitch. This BERGSTIK® II series connector is designed for board-to-board applications with unshrouded, single-row configuration and push-pull fastening. The part is currently active in production with 692 units in stock.

Substitute parts are necessary when addressing supply chain constraints, design requirement changes, or when alternative manufacturers offer improved compliance status or extended operating temperature ranges.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Connector type classification (Header with optional Breakaway feature)
Contact type (Male Pin)
Position count (36 positions)
Mating pitch (0.100" / 2.54mm)
Single-row configuration
Through-hole mounting capability
Solder termination
Push-pull fastening mechanism
Unshrouded design
Square contact shape
UL94 V-0 flammability rating
Black insulation color

All four substitute parts meet these core criteria. Variations in contact length, contact finish, contact material, operating temperature range, current rating, and RoHS compliance status do not disqualify substitution but represent design trade-offs for specific applications.

Engineering Selection Recommendations

All four substitute parts are active products with confirmed availability. Selection criteria based on compliance and certification status:

929705-06-36-I (3M): This part offers RoHS compliance and extended operating temperature range (-40°C to 105°C) compared to the original part. The gold contact finish provides enhanced corrosion resistance. However, the significantly longer post length (0.710" vs. 0.120") requires PCB design accommodation and may not be suitable for applications with space constraints. Current rating is 2.5A.

PBC36SFAN (Sullins): This part combines ROHS3 compliance with the widest operating temperature range (-65°C to 125°C) and highest current rating (3A). The gold mating contact finish with tin post finish offers a balanced approach. Post length matches the original part (0.120"), making it a direct mechanical substitute. Highest inventory availability (4272 units).

PEC36SFAN (Sullins): This part provides ROHS3 compliance, extended operating temperature range (-65°C to 125°C), and 3A current rating. Tin finish on both mating and post surfaces matches the original part specification. Post length is identical (0.120"), ensuring direct mechanical compatibility. Highest inventory level (6328 units).

PEC36SFCN (Sullins): This part offers ROHS3 compliance and extended operating temperature range (-65°C to 125°C) with 3A current rating. Tin finish matches the original specification. The longer post length (0.320" vs. 0.120") requires PCB design verification but may be beneficial for applications requiring extended insertion depth.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the 68603-436?

A: All four substitute parts share the same core functional parameters: 36-position, 0.100" pitch, single-row header with through-hole solder termination and push-pull fastening. However, physical dimensions differ, particularly post length. PBC36SFAN and PEC36SFAN have identical post lengths (0.120") to the original part and require no PCB modification. The 3M 929705-06-36-I and PEC36SFCN have longer posts and require PCB design verification.

Q: What is the difference between tin and gold contact finishes?

A: Tin finish (100.0µin / 2.54µm) provides cost-effective corrosion resistance suitable for standard applications. Gold finish (10.0µin / 0.25µm on 3M part, 10.0µin on PBC36SFAN) offers superior corrosion resistance and lower contact resistance, beneficial for high-reliability or harsh environment applications. The original 68603-436 uses tin finish; PBC36SFAN uses gold mating with tin post; PEC36SFAN and PEC36SFCN use tin on both surfaces.

Q: Why do some parts have longer post lengths?

A: Post length determines how far the solder tail extends below the PCB surface. The original part and PBC36SFAN/PEC36SFAN use 0.120" posts for standard PCB thickness. The 3M 929705-06-36-I (0.710") and PEC36SFCN (0.320") have extended posts for applications requiring deeper insertion or thicker PCB assemblies. Verify PCB design compatibility before selection.

Q: What is the significance of RoHS compliance?

A: The original 68603-436 is RoHS non-compliant, meaning it may contain restricted substances such as lead. All substitute parts (929705-06-36-I, PBC36SFAN, PEC36SFAN, PEC36SFCN) are RoHS or ROHS3 compliant, meeting environmental and regulatory requirements for new designs and markets with RoHS mandates.

Q: Which substitute part has the best operating temperature range?

A: The three Sullins parts (PBC36SFAN, PEC36SFAN, PEC36SFCN) all operate from -65°C to 125°C, providing the widest range. The 3M 929705-06-36-I operates from -40°C to 105°C. The original part does not specify an operating temperature range. Select based on your application's thermal requirements.

Q: Are there inventory considerations for these parts?

A: Current inventory levels are: PEC36SFAN (6328 units), PBC36SFAN (4272 units), 929705-06-36-I (1268 units), PEC36SFCN (1391 units), and 68603-436 (692 units). PEC36SFAN offers the highest availability for high-volume applications.

Q: What is the current rating difference, and does it matter?

A: The original part does not specify a current rating. Substitute parts are rated at 2.5A (3M 929705-06-36-I) or 3A (all Sullins parts). Current rating indicates maximum continuous current per contact. Select based on your circuit's actual current requirements; higher-rated parts provide design margin but do not improve performance in lower-current applications.
