Substitute Part Grouping Explanation

The Amphenol ICC (FCI) part number 98414-G06-34LF qualifies as a substitute for the Molex 0878313429 based on the following critical parameters:

• Connector Type & Contact Configuration: Both are male pin headers with identical 34-position, 2-row configuration
• Pitch Specifications: Both maintain 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Both feature through-hole solder termination with latch holder fastening
• Shrouding: Both incorporate shrouded 4-wall design
• Electrical Ratings: Both support 2A current rating and UL94 V-0 flammability classification
• Compliance: Both are RoHS compliant and carry EAR99 ECCN classification

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0878313429 and Amphenol ICC 98414-G06-34LF are active products with equivalent functional specifications for 34-position, 2.00mm pitch board-to-board connector applications. Selection between these parts should be based on:

• Voltage Margin: The Amphenol ICC part provides 200V rating versus 125V for the Molex part, offering additional voltage headroom for applications requiring higher electrical stress tolerance.
• Compliance Status: Both parts meet UL94 V-0 flammability requirements and carry RoHS compliance certifications suitable for regulated industries.
• Mechanical Dimensions: Minor differences exist in contact length (mating) and insulation height. The Amphenol ICC part features 0.157" mating contact length compared to 0.141" for the Molex part, and 0.232" insulation height versus 0.252" for the Molex part. These dimensional variations require verification against PCB layout and mating connector specifications.
• Supply Availability: Both parts maintain active inventory status with comparable stock levels (1137 pcs for Molex, 1118 pcs for Amphenol ICC).

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 98414-G06-34LF directly replace the Molex 0878313429 in existing designs?

A: Direct mechanical and electrical compatibility exists for the core connector function. However, the dimensional differences in contact length (mating) and insulation height require verification against the mating connector and PCB layout specifications before implementation.

Q: What are the key compatibility criteria for these rectangular connectors?

A: Compatibility is determined by matching pitch (0.079" / 2.00mm), number of positions (34), row configuration (2 rows), mounting type (through hole), shrouding style (4-wall), and termination method (solder). Both parts meet these criteria.

Q: Are there packaging differences between these parts?

A: Yes. The Molex 0878313429 is supplied in tube packaging, while the Amphenol ICC 98414-G06-34LF is supplied in bulk packaging. This affects handling, storage, and procurement workflows but does not impact functional performance.

Q: Do both parts meet automotive and telecommunications application requirements?

A: The Molex part explicitly lists automotive, general purpose, and telecommunications applications. The Amphenol ICC part does not specify applications in the provided data. Both parts meet UL94 V-0 and RoHS compliance standards applicable to these industries.

Q: What is the significance of the voltage rating difference?

A: The Amphenol ICC part is rated for 200V (AC/DC) compared to 125V for the Molex part. This provides additional safety margin in high-voltage applications but does not affect compatibility in designs operating within the 125V specification.
