Amphenol ICC 66226-014 FFC Connector Header Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66226-014 is a 14-position FFC (Flat Flexible Cable) connector header with 0.100" (2.54mm) pitch, designed for free-hanging in-line mounting applications. This connector features IDC (Insulation Displacement Contact) termination and is rated for 500V operation across a temperature range of -65°C to 105°C. The part is currently active in production with 687 units available in inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component sourcing flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

The 66226-014LF qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Electrical Compatibility: Identical voltage rating (500V), current rating (2A), and contact material (Copper Nickel Alloy with Tin finish)
• Mechanical Compatibility: Same number of positions (14), pitch (0.100"/2.54mm), connector type (Header), and mounting configuration (Free Hanging In-Line)
• Environmental Ratings: Matching operating temperature range (-65°C ~ 105°C) and flammability rating (UL94 V-0)
• Series Consistency: Both parts belong to the Clincher™ series from Amphenol ICC (FCI)
• Mating Cycles: Equivalent mechanical durability specification (100 cycles)

The primary difference between these parts is the termination method: the 66226-014 uses IDC termination, while the 66226-014LF uses solder termination. This distinction affects assembly methodology but does not alter electrical or mechanical compatibility in applications where the termination type is appropriate.

Parameter Comparison

Engineering Selection Recommendations

Both the 66226-014 and 66226-014LF are active production parts from Amphenol ICC (FCI) with equivalent electrical and mechanical specifications. Selection between these parts depends on assembly methodology and regulatory requirements:

The 66226-014LF offers RoHS compliance and REACH affected status, making it suitable for applications subject to environmental regulations. The 66226-014 remains non-compliant with RoHS but maintains full electrical and mechanical equivalence for applications without such constraints.

The termination difference (IDC versus solder) is the primary technical distinction. IDC termination in the 66226-014 provides tool-based assembly without soldering, while solder termination in the 66226-014LF requires thermal processing. Both termination methods deliver equivalent electrical performance when properly executed.

The 66226-014LF supports both 0.30mm and 0.33mm FFC thickness, providing broader cable compatibility compared to the 66226-014 specification of 0.33mm. The 66226-014LF also includes slide lock and zero insertion force (ZIF) features with solder retention capability.

Frequently Asked Questions (FAQ)

Q: Can the 66226-014 and 66226-014LF be used interchangeably in the same application?

A: Electrical and mechanical interchangeability is confirmed based on matching voltage rating (500V), current rating (2A), position count (14), pitch (2.54mm), and operating temperature range (-65°C ~ 105°C). Interchangeability depends on assembly methodology: IDC termination (66226-014) requires crimping tools, while solder termination (66226-014LF) requires reflow or wave soldering equipment. Select based on your assembly process capability.

Q: What is the difference between IDC and solder termination?

A: IDC (Insulation Displacement Contact) termination in the 66226-014 pierces the cable insulation without stripping, using mechanical pressure from a crimping tool. Solder termination in the 66226-014LF requires thermal bonding of the cable to the connector contacts. Both methods achieve equivalent electrical connections when properly executed with appropriate equipment.

Q: Does the 66226-014LF support different FFC cable thicknesses?

A: Yes. The 66226-014LF accommodates both 0.30mm and 0.33mm FFC thickness, while the 66226-014 is specified for 0.33mm only. This broader compatibility in the 66226-014LF provides flexibility for cable sourcing.

Q: What is the significance of RoHS compliance difference between these parts?

A: The 66226-014LF is RoHS compliant, meeting restrictions on hazardous substances in electrical and electronic equipment. The 66226-014 is RoHS non-compliant. Select the RoHS-compliant 66226-014LF for applications subject to environmental regulations or customer requirements mandating RoHS compliance.

Q: Are both parts suitable for the same voltage and current applications?

A: Yes. Both parts share identical voltage rating (500V) and current rating (2A), confirming electrical equivalence for power delivery specifications.

Q: What does the Clincher™ series designation indicate?

A: Clincher™ is the Amphenol ICC (FCI) product series designation for these FFC connector headers. Both the 66226-014 and 66226-014LF belong to this series, indicating design family consistency and compatibility within the series ecosystem.
