P3203ACL60 Equivalent & Substitute Parts

Part Overview

The P3203ACL60 is a 270V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This three-element device is housed in a TO-220 Modified package (3-SIP configuration) and is designed for transient voltage suppression applications requiring high current handling capability. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when electrical parameters, mechanical packaging, and compliance certifications remain equivalent across the component family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P3203ACL60 is determined by exact equivalence across the following critical parameters: voltage ratings (breakover, off-state, and on-state), peak pulse current specifications (both 8/20µs and 10/1000µs ratings), hold current, element count, capacitance values, physical package configuration, and compliance certifications. The P3203ACL qualifies as a direct substitute because it maintains identical electrical specifications, mechanical packaging (3-SIP TO-220 Modified), and regulatory compliance status. Both parts are manufactured by Littelfuse Inc. within the SIDACtor® series and retain Active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the P3203ACL60 and P3203ACL are qualified for direct substitution in applications requiring 270V off-state TVS thyristor protection with 400A peak pulse current handling. Selection between these parts is based on inventory availability and supply chain considerations rather than electrical or mechanical differentiation. The P3203ACL maintains 1600 units in stock compared to 698 units for the P3203ACL60, providing enhanced supply continuity. Both parts maintain Active product status, full RoHS3 compliance, and REACH unaffected classification, ensuring regulatory compatibility across current and future procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can P3203ACL be used as a direct replacement for P3203ACL60? A: Yes. Both parts are electrically and mechanically identical, with matching voltage ratings (350V breakover, 270V off-state, 8V on-state), current specifications (400A peak pulse at 8/20µs, 100A at 10/1000µs), and physical packaging (3-SIP TO-220 Modified through-hole configuration).

Q: Are there differences in compliance or certifications between these parts? A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity ratings.

Q: What determines substitution eligibility for TVS thyristors in this category? A: Substitution requires exact equivalence in breakover voltage, off-state voltage, on-state voltage, peak pulse current ratings (both 8/20µs and 10/1000µs specifications), hold current, element count, capacitance values, physical package type, and regulatory compliance certifications.

Q: Are there any package or mounting differences? A: No. Both the P3203ACL60 and P3203ACL use identical 3-SIP packaging with TO-220 Modified supplier configuration and through-hole mounting.

Q: Which part should be selected for new designs? A: Either part is suitable for new designs. Selection may be based on current inventory levels and supplier availability, as electrical and mechanical specifications are fully equivalent.
