Key Parameters

Substitute Part Grouping Explanation

The P2353AB60 has one direct equivalent substitute: P2353ABL60. Substitution eligibility is determined by the following critical parameters:

• Voltage ratings (breakover, off-state, on-state) must be identical
• Peak pulse current specifications (8/20µs and 10/1000µs) must match exactly
• Hold current (Ih) must be identical
• Number of elements must be the same
• Package and mounting type must be identical
• Capacitance values must be within the same range

The P2353ABL60 meets all these criteria, providing functional equivalence with the obsolete P2353AB60.

Parameter Comparison

Engineering Selection Recommendations

The P2353ABL60 is the direct substitute for the obsolete P2353AB60. Selection of the P2353ABL60 is supported by:

• Identical electrical performance across all specified parameters
• Active product status ensuring continued availability
• ROHS3 compliance, addressing regulatory requirements not met by the original part
• Equivalent moisture sensitivity rating and handling requirements
• Same packaging and mounting configuration, enabling direct board-level replacement

The transition from P2353AB60 to P2353ABL60 requires no circuit redesign or thermal management modifications.

Frequently Asked Questions (FAQ)

Q: Can P2353ABL60 be used as a direct replacement for P2353AB60?

A: Yes. The P2353ABL60 provides identical electrical performance across all specified parameters including voltage ratings, peak pulse currents, hold current, and capacitance values. The package and mounting type are identical, enabling direct substitution.

Q: What is the difference between P2353AB60 and P2353ABL60?

A: The primary differences are product status and compliance. P2353AB60 is obsolete and RoHS non-compliant, while P2353ABL60 is active and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: No. Both parts use the same 3-SIP TO-220 modified package with through-hole mounting. No PCB layout modifications are required.

Q: Does the RoHS3 compliance of P2353ABL60 affect circuit performance?

A: No. RoHS3 compliance indicates material composition standards and does not alter electrical performance, thermal characteristics, or functional behavior in the circuit.

Q: What is the inventory status of these parts?

A: P2353AB60 has 843 pieces in stock (obsolete status). P2353ABL60 has 735 pieces in stock and is actively produced by Littelfuse Inc.
