Littelfuse P1100EA TVS Thyristor Equivalent & Substitute Parts

Part Overview

The Littelfuse P1100EA is a 90V off-state transient voltage suppressor (TVS) thyristor in the SIDACtor® series, rated for 150A peak pulse current (8/20µs). This component is designed for transient overvoltage protection in electronic circuits requiring fast response and high current handling capability.

The P1100EA is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1100EA is determined by electrical and mechanical parameter equivalence within the SIDACtor® TVS thyristor product line. The following parameters establish substitution validity:

• Voltage ratings (breakover, off-state, and on-state) must match exactly
• Peak pulse current ratings (both 8/20µs and 10/1000µs) must match exactly
• Hold current (Ih) must match exactly
• Capacitance must match exactly
• Package and mounting type must be identical or mechanically compatible
• Number of elements must be identical

The P1100EAL meets all substitution criteria as a direct equivalent to the P1100EA, with identical electrical specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The P1100EAL is the direct substitute for the obsolete P1100EA. Both components share identical electrical specifications and mechanical packaging.

Key differentiation factors:

• P1100EA: Obsolete product status; RoHS non-compliant
• P1100EAL: Active product status; ROHS3 compliant; REACH unaffected

For new designs or ongoing production requiring transient voltage suppression at 90V off-state with 150A peak pulse capability, the P1100EAL is the appropriate selection. The active product status and RoHS3 compliance of the P1100EAL provide regulatory alignment and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the P1100EAL be used as a direct replacement for the P1100EA?

A: Yes. The P1100EAL is electrically and mechanically identical to the P1100EA. All voltage ratings, current ratings, capacitance, and package specifications match exactly. The components are pin-compatible and functionally equivalent.

Q: What is the difference between the P1100EA and P1100EAL?

A: The primary differences are product status and regulatory compliance. The P1100EA is obsolete and RoHS non-compliant. The P1100EAL is an active product that meets ROHS3 compliance standards. Electrical and mechanical specifications are identical.

Q: Are there any package or mounting differences between these parts?

A: No. Both the P1100EA and P1100EAL use the TO-226-2 and TO-92-2 (TO-226AC) package with through-hole mounting. They are mechanically interchangeable.

Q: Why should I select the P1100EAL over the P1100EA?

A: The P1100EAL should be selected because it is an active product with current manufacturing support and RoHS3 compliance. The P1100EA is obsolete and may face supply constraints. For new applications or ongoing production, the P1100EAL ensures regulatory compliance and supply chain reliability.

Q: What are the key electrical parameters that define substitution for this TVS thyristor?

A: Substitution is determined by exact matching of breakover voltage (130V), off-state voltage (90V), on-state voltage (4V), peak pulse current ratings (150A at 8/20µs and 45A at 10/1000µs), hold current (150mA), and capacitance (50pF). Package type and mounting method must also be identical.
