P0900ECAP Equivalent & Substitute Parts

Part Overview

The P0900ECAP is a 75V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring through-hole mounting in TO-226-2 or TO-92-2 packages. The P0900ECAP is currently classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0900ECAP is determined by matching the following critical electrical and mechanical parameters:

• Voltage - Off State: 75V
• Voltage - Breakover: 98V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Capacitance: 140pF
• Number of Elements: 1
• Mounting Type: Through Hole
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)

The P0900ECLAP meets all these criteria and is therefore a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P0900ECLAP is the direct substitute for the obsolete P0900ECAP. Both components share identical electrical specifications and mechanical packaging. The P0900ECLAP is currently in active production status, ensuring availability for new designs and system replacements.

The P0900ECLAP offers improved compliance status: it is ROHS3 compliant and REACH unaffected, whereas the P0900ECAP is RoHS non-compliant. For applications subject to environmental or regulatory requirements, the P0900ECLAP is the appropriate selection. The P0900ECLAP is supplied in Tape & Box packaging, suitable for both manual and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the P0900ECLAP directly replace the P0900ECAP in existing designs?

A: Yes. The P0900ECLAP is electrically and mechanically identical to the P0900ECAP. All voltage ratings, current specifications, capacitance, and package dimensions are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between P0900ECAP and P0900ECLAP?

A: The primary differences are product status and compliance. The P0900ECAP is obsolete and RoHS non-compliant. The P0900ECLAP is active production and ROHS3 compliant. Packaging differs: P0900ECAP is supplied loose, while P0900ECLAP is supplied in Tape & Box format.

Q: Are there any performance differences between these parts?

A: No. Both parts are rated for identical electrical performance: 75V off-state voltage, 98V breakover voltage, 400A peak pulse current (8/20µs), and 150mA hold current. Functional behavior in circuit is identical.

Q: Which part should be selected for new designs?

A: The P0900ECLAP should be selected for new designs. It is in active production, offers improved regulatory compliance, and ensures long-term availability.

Q: Is the TO-226-2 package compatible with TO-92-2 footprints?

A: Both the P0900ECAP and P0900ECLAP are available in TO-226-2 and TO-92-2 (TO-226AC) package options with formed leads. Verify the specific package variant required for your application footprint.
