Amphenol ICC 90309-326 Equivalent & Substitute Parts
Part Overview
The Amphenol ICC 90309-326 is a rectangular connector header designed for through-hole board-to-board applications. This shrouded 26-position connector operates at 2A and 200V with a 2mm pitch configuration. The part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation
The 90309-326LF 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 position count remain unchanged (Header, Male Pin, 26 positions)
- Pitch and row spacing match exactly (0.079" / 2.00mm)
- Mounting configuration is identical (Through Hole, Shrouded - 2 Wall)
- Electrical ratings are equivalent or exceed requirements (2A / 200V minimum)
- Contact finish specifications are maintained (Gold mating surface, Tin post finish)
- Flammability and material compliance are preserved (UL94 V-0)
The primary distinction between these parts is product status and RoHS compliance, not functional or dimensional characteristics.

Engineering Selection Recommendations
The 90309-326LF is the direct active equivalent for the obsolete 90309-326. Both parts share identical electrical specifications, mechanical dimensions, and contact configurations. The 90309-326LF carries active product status and RoHS compliance certification, making it the appropriate selection for new designs and ongoing production requirements. No functional or dimensional modifications are required when transitioning from the 90309-326 to the 90309-326LF.
Frequently Asked Questions (FAQ)
Q: Are the 90309-326 and 90309-326LF mechanically interchangeable?
A: Yes. Both parts feature identical connector type, position count, pitch, row spacing, shrouding configuration, and mounting method. PCB footprints and mating interface dimensions are equivalent.
Q: What is the significance of the "LF" suffix in the 90309-326LF part number?
A: The "LF" designation indicates lead-free construction and RoHS compliance. The 90309-326LF meets RoHS requirements, whereas the original 90309-326 does not specify this compliance.
Q: Can the 90309-326LF handle the same electrical load as the 90309-326?
A: Yes. Both parts are rated for 2A at 200V (AC/DC). Electrical performance and current-carrying capacity are identical.
Q: Are there packaging differences between these parts?
A: The 90309-326LF is supplied in bag packaging. The original 90309-326 packaging specification is not provided in the technical data.
Q: What contact finish specifications apply to both parts?
A: Both parts feature gold-plated mating contacts (GXT™ finish, 15.0µin thickness) and tin-plated posts (78.7µin thickness). Contact material is copper alloy in both cases.
Q: Is the keying slot feature present on both parts?
A: Yes. Both the 90309-326 and 90309-326LF include keying slot features for polarization control.
