P1100ECAP Equivalent & Substitute Parts

Part Overview

The P1100ECAP is a 90V off-state TVS thyristor from Littelfuse Inc.'s SIDACtor® series, designed for transient voltage suppression applications. It features a 400A peak pulse current rating (8/20µs) and is packaged in TO-226-2/TO-92-2 through-hole configuration. The P1100ECAP is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1100ECAP is determined by electrical and mechanical parameter equivalence within the SIDACtor® TVS thyristor category. The critical parameters governing substitution are:

• Voltage - Off State: 90V
• Voltage - Breakover: 130V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Capacitance: 115pF
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole

The P1100ECLAP meets all electrical and mechanical specifications identical to the P1100ECAP, with the primary distinction being packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P1100ECLAP is the direct substitute for the obsolete P1100ECAP. Both components share identical electrical characteristics and mechanical specifications. The P1100ECLAP is currently in active production status, ensuring availability for new designs and replacement applications.

The P1100ECLAP provides ROHS3 compliance, whereas the P1100ECAP is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the P1100ECLAP is the appropriate selection. The P1100ECLAP is supplied in Tape & Box packaging format, compared to the P1100ECAP's standard packaging.

Frequently Asked Questions (FAQ)

Q: Can the P1100ECLAP directly replace the P1100ECAP in existing designs?

A: Yes. The P1100ECLAP is electrically and mechanically equivalent to the P1100ECAP. All voltage ratings, current specifications, capacitance values, and package configurations are identical. The components are pin-compatible and functionally interchangeable.

Q: What is the primary difference between these two parts?

A: The P1100ECAP is obsolete, while the P1100ECLAP is in active production. The P1100ECLAP also provides ROHS3 compliance, whereas the P1100ECAP is RoHS non-compliant. Packaging format differs: P1100ECLAP is supplied in Tape & Box configuration.

Q: Are there any compatibility concerns with the TO-226-2/TO-92-2 package?

A: No. Both parts use identical through-hole package specifications. PCB footprints, lead spacing, and mounting requirements are equivalent.

Q: Why is the P1100ECAP classified as obsolete?

A: The P1100ECAP has been superseded by the P1100ECLAP in Littelfuse Inc.'s product portfolio. The P1100ECLAP provides the same electrical and mechanical functionality with improved compliance status and active manufacturing support.

Q: Is the P1100ECLAP suitable for new designs?

A: Yes. The P1100ECLAP is in active production status and is the recommended selection for new designs requiring 90V off-state TVS thyristor functionality in the SIDACtor® series.
