P1553ABL60 Equivalent & Substitute Parts

Part Overview

The P1553ABL60 is a 130V off-state, 250A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This three-element device is housed in a TO-220 Modified package 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. Substitute parts are identified to provide equivalent electrical and mechanical performance for applications where the primary part number is unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P1553ABL60 is determined by exact equivalence across all critical electrical parameters and mechanical specifications. The substitute part P1553ABL qualifies as a direct equivalent based on identical values for voltage ratings (breakover, off-state, and on-state), peak pulse current specifications (both 8/20µs and 10/1000µs ratings), hold current, element count, capacitance range, package type, and mounting configuration. Both parts are manufactured by Littelfuse Inc. within the SIDACtor® series and maintain identical compliance certifications. Substitution is valid when the application requires these exact electrical characteristics and the TO-220 Modified through-hole package configuration.

Parameter Comparison

Engineering Selection Recommendations

The P1553ABL serves as a direct substitute for the P1553ABL60 in applications requiring identical electrical performance and mechanical compatibility. Both parts maintain active product status from Littelfuse Inc., ensuring continued manufacturing support and supply chain availability. Selection between these part numbers should be based on inventory availability and procurement lead times, as they are electrically and mechanically interchangeable. Both parts satisfy RoHS3 compliance requirements and REACH regulatory obligations, making them suitable for applications subject to these standards. The unlimited moisture sensitivity rating (MSL 1) permits storage and handling without time-dependent constraints.

Frequently Asked Questions (FAQ)

Q: Can P1553ABL be used as a direct replacement for P1553ABL60? A: Yes. Both parts are manufactured by Littelfuse Inc. and share identical electrical specifications including voltage ratings, peak pulse current ratings, hold current, element count, and capacitance values. The TO-220 Modified package and through-hole mounting configuration are identical, confirming direct substitutability.

Q: Are there any differences in compliance or certifications between these parts? A: No. Both P1553ABL60 and P1553ABL maintain identical RoHS3 compliance status, REACH unaffected designation, and MSL 1 (unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: What determines whether a part can substitute for the P1553ABL60? A: Substitution eligibility is determined by exact equivalence in voltage ratings (breakover, off-state, on-state), peak pulse current specifications (8/20µs and 10/1000µs), hold current, element count, capacitance range, package type (3-SIP), and mounting configuration (through-hole). All these parameters must match precisely.

Q: Does the package configuration affect substitutability? A: Yes. Both parts use the TO-220 Modified package in 3-SIP configuration with through-hole mounting. Any variation in package type or mounting method would disqualify a part from substitution.

Q: Are there inventory or lead time considerations for selecting between these part numbers? A: Inventory levels may differ between part numbers. P1553ABL60 has 1109 pieces in stock, while P1553ABL has 5200 pieces available. Selection should account for project timelines and procurement requirements.
