Amphenol ICC 90309-124 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 90309-124 is a shrouded rectangular connector header designed for through-hole board-to-board applications. This 24-position, 2-row connector operates at 2A (AC/DC) and 200V (AC/DC) with a 0.079" (2.00mm) pitch configuration. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The 90309-124LF qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type, contact type, and gender remain unchanged (Header, Male Pin)
• Position count and row configuration are identical (24 positions, 2 rows)
• Pitch specifications match exactly (0.079" mating pitch, 0.079" row spacing)
• Mounting method is identical (Through Hole)
• Shrouding configuration matches (Shrouded - 2 Wall)
• Current and voltage ratings are equal or exceed requirements (2A, 200V)
• Contact finish specifications are equivalent (Gold mating surface)
• Flammability rating meets or exceeds original specification (UL94 V-0)

The primary distinction between the main part and substitute is product status and compliance certification, not functional or dimensional characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 90309-124LF is the direct functional equivalent of the 90309-124. All electrical and mechanical parameters are identical. The primary advantages of selecting the 90309-124LF are:

• Active product status ensures ongoing availability and manufacturer support
• RoHS Compliant certification meets current environmental regulations
• REACH Affected status indicates compliance with chemical substance restrictions
• Bulk packaging option provides flexibility for procurement strategies

The 90309-124 is classified as obsolete. For new designs or system refreshes, the 90309-124LF is the appropriate selection. For legacy system maintenance where original part specifications must be preserved, the 90309-124LF maintains full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 90309-124LF be used as a direct replacement for the 90309-124?
