Key Parameters

Substitute Part Grouping Explanation

Substitution of the CNC Tech 3110-24-003-13-99 is determined by the following critical parameters that must remain consistent:

• Connector Type & Contact Type: Header with male pins
• Position Count & Row Configuration: 24 positions in 2 rows
• Pitch Specifications: 0.079" (2.00mm) mating pitch and row spacing
• Mounting Technology: Surface mount solder termination
• Shrouding Configuration: Shrouded 4-wall design
• Electrical Performance: Current and voltage ratings must meet or exceed original specifications
• Environmental Compliance: RoHS compliance and flammability rating (UL94 V-0)
• Mechanical Interface: Square contact shape and keying slot presence

The Amphenol ICC (FCI) 10078995-G01-24BLF satisfies all critical substitution criteria. This part maintains identical position count, pitch, row configuration, mounting type, and shrouding. The substitute is active in production status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 10078995-G01-24BLF is a direct functional substitute for the obsolete CNC Tech 3110-24-003-13-99. Selection of this substitute is supported by the following factors:

Mechanical Compatibility: All critical dimensional and positional parameters are identical, including 24-position count, 2-row configuration, 0.079" (2.00mm) pitch, and shrouded 4-wall construction. The keying slot feature is present on both parts, ensuring proper mating orientation.

Electrical Performance: The substitute part exceeds the original current rating (2A versus 1A) and provides specified voltage rating (200V AC/DC), delivering enhanced electrical capability within the same physical envelope.

Regulatory Compliance: Both parts maintain UL94 V-0 flammability rating and RoHS compliance, satisfying environmental and safety requirements. Moisture sensitivity level remains at MSL 1 (Unlimited) on both parts.

Supply Chain Status: The substitute part is active in production with established inventory availability, eliminating obsolescence risk associated with the original CNC Tech component.

Contact Finish Differences: The substitute features gold-plated contacts (GXT™ mating finish with 30.0µin thickness) compared to the original tin finish (80.0µin thickness). Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10078995-G01-24BLF be used as a direct replacement in existing designs?

A: Yes. The substitute maintains identical mechanical and electrical interfaces. All critical parameters including position count, pitch, row spacing, mounting type, and shrouding are identical. The part will mate with existing cable assemblies and PCB layouts designed for the original CNC Tech component.

Q: What are the differences in contact finish between the original and substitute parts?

A: The original CNC Tech part features tin plating at 80.0µin thickness on mating contacts. The Amphenol ICC substitute uses gold plating (GXT™) at 30.0µin thickness on mating contacts with gold flash on posts. Gold plating provides superior corrosion resistance and is suitable for applications requiring extended shelf life or exposure to corrosive environments.

Q: Does the higher current rating of the substitute part affect compatibility?

A: No. The substitute's 2A current rating exceeds the original 1A specification, providing additional electrical margin. This enhancement does not compromise compatibility and may improve performance in current-sensitive applications.

Q: Are there packaging differences between the original and substitute parts?

A: The original CNC Tech part packaging is not specified. The Amphenol ICC substitute is supplied in tube packaging. Verify tube packaging compatibility with your assembly and handling processes.

Q: What is the operating temperature range for the substitute part?

A: The operating temperature range for the Amphenol ICC substitute is not specified in the provided data. The original CNC Tech part operates from -40°C to 105°C. Confirm temperature requirements with Amphenol ICC technical documentation if operation outside standard industrial ranges is required.

Q: Are both parts RoHS compliant?

A: Yes. The original CNC Tech 3110-24-003-13-99 is ROHS3 compliant. The Amphenol ICC 10078995-G01-24BLF is RoHS compliant. Both parts satisfy RoHS requirements for lead-free and restricted substance compliance.
