Amphenol ICC 861400142YO2 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 861400142YO2 is a vertical rectangular header connector from the BERGSTIK® series, designed for through-hole board-to-board or cable applications. This 14-position connector with 2.54mm pitch provides solder termination and push-pull fastening for applications requiring 3A current capacity at 1000V. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 861400142YO6LF is classified as a direct equivalent based on the following critical parameters that determine substitutability:

• Connector Type & Configuration: Both parts are Header, Breakaway connectors with identical 14-position, 2-row configuration
• Pitch & Spacing: Both maintain 0.100" (2.54mm) mating pitch and row spacing
• Electrical Ratings: Both support 3A current and 1000V voltage specifications
• Mounting & Termination: Both use through-hole mounting with solder termination
• Operating Environment: Both rated for -55°C ~ 125°C temperature range and UL94 V-0 flammability
• Contact Configuration: Both feature male pin contacts with square contact shape and copper alloy material

The primary differences between these parts are product status (obsolete vs. active), RoHS compliance status, and contact finish thickness specifications, which do not affect functional interchangeability in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

The 861400142YO6LF serves as the active production equivalent for the obsolete 861400142YO2. Selection between these parts should be based on the following criteria:

Use 861400142YO6LF when:

• New designs or production runs require active component availability
• RoHS compliance is mandated by application requirements or regulatory standards
• Long-term supply chain continuity is required

Use 861400142YO2 when:

• Existing inventory of the obsolete part is available and acceptable for legacy system support
• RoHS non-compliance does not conflict with application requirements
• Cost considerations favor existing stock utilization

Both parts maintain identical electrical and mechanical specifications for connector pitch, position count, current and voltage ratings, and operating temperature range. The increased contact finish thickness in the 861400142YO6LF (29.5µin vs. 8.00µin) provides enhanced durability and wear resistance without affecting functional compatibility.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable? A: Yes. Both parts share identical pitch (2.54mm), position count (14), row configuration (2 rows), and mounting type (through-hole). They are mechanically interchangeable in board layouts and mechanical assemblies.

Q: What is the difference in contact finish thickness, and does it affect performance? A: The 861400142YO6LF has a thicker gold plating (29.5µin vs. 8.00µin). This provides increased contact durability and resistance to wear from repeated mating cycles, but does not affect electrical performance in standard applications.

Q: Can I use the RoHS-compliant part as a direct replacement for the non-compliant version? A: Yes, from an electrical and mechanical standpoint. However, verify that your application and supply chain requirements do not specifically mandate the non-compliant version. The RoHS-compliant 861400142YO6LF is the recommended choice for new designs.

Q: What is the packaging difference between these parts? A: The 861400142YO2 packaging is not specified in available data. The 861400142YO6LF is supplied in bag packaging. Confirm packaging requirements with your procurement specifications.

Q: Are both parts rated for the same electrical specifications? A: Yes. Both parts are rated for 3A current, 1000V voltage, and operate across the -55°C ~ 125°C temperature range with UL94 V-0 flammability rating.

Q: Which part should I specify for new designs? A: Specify 861400142YO6LF for new designs. It is the active production part with RoHS compliance and improved contact durability through increased plating thickness.
