Littelfuse P1300EC TVS Thyristor Equivalent & Substitute Parts

Part Overview

The Littelfuse P1300EC is a 120V off-state, 400A peak pulse TVS thyristor in TO-226-2 packaging, part of the SIDACtor® series. This component is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The P1300EC provides transient voltage suppression through a thyristor-based architecture with a 160V breakover voltage and 4V on-state voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1300EC is determined by electrical and mechanical parameter equivalence within the TVS thyristor category. The following parameters establish substitution validity:

• Voltage ratings (breakover, off-state, and on-state) must match exactly
• Peak pulse current ratings (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
• Number of elements must be identical

The P1300ECL meets all substitution criteria as a direct equivalent, with identical electrical specifications and packaging. The primary distinction is product status: P1300ECL is active and RoHS3 compliant, whereas P1300EC is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The P1300ECL is the direct substitute for the P1300EC. All electrical parameters and mechanical specifications are identical. Selection of P1300ECL is appropriate for:

• Replacement in existing designs currently using P1300EC
• New production designs requiring 120V off-state, 400A peak pulse TVS thyristor functionality
• Applications requiring RoHS3 compliance

The P1300ECL maintains active product status with established supply availability (54,672 pcs in stock), whereas P1300EC is obsolete with limited remaining inventory (691 pcs). The P1300ECL is REACH unaffected, providing additional regulatory compliance assurance.

Frequently Asked Questions (FAQ)

Q: Can P1300ECL be used as a direct replacement for P1300EC?

A: Yes. All electrical parameters (voltage ratings, current ratings, capacitance) and mechanical specifications (package, mounting type) are identical. P1300ECL is the active equivalent.

Q: What is the difference between P1300EC and P1300ECL?

A: The primary differences are product status and compliance certifications. P1300EC is obsolete and RoHS non-compliant. P1300ECL is active, RoHS3 compliant, and REACH unaffected. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use TO-226-2 and TO-92-2 (TO-226AC) packaging with through-hole mounting. Pinout and mechanical dimensions are identical.

Q: What parameters must match for substitution validity?

A: Breakover voltage (160V), off-state voltage (120V), on-state voltage (4V), peak pulse current ratings (400A at 8/20µs, 100A at 10/1000µs), hold current (150mA), capacitance (105pF), package type, and mounting method must all match exactly.

Q: Is P1300ECL suitable for new designs?

A: Yes. P1300ECL is active and compliant with current regulatory requirements (RoHS3, REACH unaffected), making it appropriate for new product development.
