Key Parameters

Substitute Part Grouping Explanation

The P1553ACL60 qualifies as a direct substitute for the P1553AC60 based on electrical and mechanical parameter equivalence. Substitution is valid when the following criteria are met:

• Identical voltage ratings: breakover voltage of 180V, off-state voltage of 130V, and on-state voltage of 8V
• Identical current specifications: peak pulse current of 400A (8/20µs) and 100A (10/1000µs), with hold current of 150mA
• Matching element count: 3 elements
• Identical capacitance values: 60pF and 95pF
• Identical package configuration: 3-SIP with TO-220 Modified supplier device package
• Through-hole mounting compatibility

The P1553ACL60 meets all these criteria and is the direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The P1553ACL60 is the appropriate substitute for the obsolete P1553AC60. Both parts are manufactured by Littelfuse and share identical electrical and mechanical specifications across all critical parameters. The P1553ACL60 offers the additional advantage of active product status and ROHS3 compliance, making it suitable for new designs and systems requiring regulatory compliance. The transition from P1553AC60 to P1553ACL60 requires no circuit modifications or design changes, as all functional parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can P1553ACL60 be used as a direct replacement for P1553AC60 in existing designs?

A: Yes. The P1553ACL60 is electrically and mechanically identical to the P1553AC60 across all specified parameters, including voltage ratings, current handling, element count, capacitance, and package configuration. No circuit modifications are required.

Q: What is the difference between P1553AC60 and P1553ACL60?

A: The primary differences are product status and compliance certification. The P1553AC60 is obsolete and non-RoHS compliant, while the P1553ACL60 is an active product with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: No. Both parts use the identical 3-SIP package with TO-220 Modified supplier device package configuration. Through-hole mounting compatibility is maintained.

Q: Why should I transition from P1553AC60 to P1553ACL60?

A: The P1553AC60 is obsolete and subject to discontinuation. The P1553ACL60 is an active product with guaranteed availability and ROHS3 compliance, ensuring long-term supply chain reliability and regulatory compliance for new and ongoing applications.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Breakover voltage, off-state voltage, on-state voltage, peak pulse currents, hold current, element count, and capacitance values are identical across both parts.
