Key Parameters

Substitute Part Grouping Explanation

The Amphenol ICC (FCI) part number 98414-G06-34LF qualifies as a direct substitute for the Molex 0878313421 based on the following critical parameters:

• Connector configuration: Both are 34-position, 2-row headers with 0.079" (2.00mm) pitch and row spacing
• Contact system: Both feature male pin contacts with square shape and gold mating finish
• Mounting and termination: Both use through-hole solder termination with latch holder fastening
• Shrouding: Both incorporate shrouded 4-wall design
• Electrical ratings: Both support 2A current and meet UL94 V-0 flammability requirements
• Environmental compliance: Both are RoHS compliant and have MSL 1 rating

The substitute part maintains mechanical and electrical compatibility while offering alternative sourcing from a different manufacturer within the same connector family classification.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0878313421 and Amphenol ICC 98414-G06-34LF are active products with equivalent core specifications for rectangular connector header applications. Selection between these parts should be based on:

• Supply availability: The Amphenol ICC part currently has 1118 units in stock versus 892 units for the Molex part
• Compliance requirements: Both meet UL94 V-0 flammability and RoHS compliance standards
• Voltage margin: The Amphenol ICC part offers 200V rating compared to 125V for the Molex part, providing additional design margin for applications operating below 125V
• Contact engagement length: The Amphenol ICC part features 0.157" (4.00mm) mating contact length versus 0.141" (3.60mm) for the Molex part, which may affect mating force characteristics in specific connector designs
• Packaging format: Molex supplies in tube packaging while Amphenol ICC supplies in bulk packaging

Both parts maintain identical electrical performance at rated specifications and are suitable for direct substitution in board-to-board and cable connector applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 98414-G06-34LF directly replace the Molex 0878313421 in existing designs?

A: Yes. Both connectors share identical pitch (2.00mm), position count (34), row configuration (2), contact type (male pin), and mounting method (through-hole solder). The mechanical and electrical compatibility is maintained across both parts.

Q: What is the difference in contact engagement length between these parts?

A: The Molex part has 0.141" (3.60mm) mating contact length while the Amphenol ICC part has 0.157" (4.00mm). This 0.016" difference may affect mating force and connector stack height in applications with tight mechanical constraints.

Q: Are there compliance differences between the two parts?

A: Both parts meet UL94 V-0 flammability requirements and RoHS compliance. The Molex part is ROHS3 compliant while the Amphenol ICC part is RoHS compliant. Both have MSL 1 rating with unlimited moisture sensitivity.

Q: What is the voltage rating difference?

A: The Molex part is rated for 125V while the Amphenol ICC part is rated for 200V. For applications operating at or below 125V, both parts are suitable. The Amphenol ICC part provides additional voltage margin for designs requiring higher ratings.

Q: Does packaging format affect part selection?

A: The Molex part is supplied in tube packaging while the Amphenol ICC part is supplied in bulk packaging. Packaging selection depends on manufacturing processes, inventory management, and handling requirements specific to your production environment.

Q: Are the insulation materials compatible?

A: The Molex part uses polyamide (PA) nylon with glass fill while the Amphenol ICC part uses thermoplastic material. Both meet UL94 V-0 flammability standards and are suitable for the specified operating temperature range.
