Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2202AB is determined by strict equivalence across the following critical parameters:

• Voltage ratings (Breakover: 130V/260V; Off-State: 90V/180V)
• Peak pulse current capability (250A at 8/20µs; 80A at 10/1000µs)
• Hold current (150 mA minimum)
• Dual-element configuration (2 elements)
• Physical package (3-SIP TO-220 Modified)
• Through-hole mounting compatibility

Parts meeting all these specifications are classified as direct functional equivalents and may be used interchangeably in circuit applications designed for the P2202AB.

Parameter Comparison

Engineering Selection Recommendations

The P2202ABL is a direct electrical and mechanical equivalent to the P2202AB, with identical performance specifications across all critical parameters. The primary distinction between these components is product lifecycle status and regulatory compliance.

The P2202AB is obsolete and carries RoHS non-compliant status. The P2202ABL is an active product with ROHS3 compliance and REACH unaffected designation, making it the appropriate selection for new designs and systems requiring current regulatory compliance. Both components are manufactured by Littelfuse Inc. within the SIDACtor® series and maintain identical electrical characteristics, package geometry, and mounting requirements.

For applications currently using the P2202AB, the P2202ABL provides a direct replacement without circuit modification or re-qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the P2202ABL replace the P2202AB in existing designs?

A: Yes. The P2202ABL is electrically and mechanically identical to the P2202AB. All voltage ratings, current specifications, hold current, capacitance values, and package dimensions are equivalent. Direct substitution is possible without circuit changes.

Q: What is the primary reason to transition from P2202AB to P2202ABL?

A: The P2202AB is obsolete. The P2202ABL is an active product with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory alignment for new and ongoing applications.

Q: Are there any package or mounting differences between these parts?

A: No. Both components use the 3-SIP TO-220 Modified package with through-hole mounting. Pin configuration and physical dimensions are identical.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution requires equivalence in breakover voltage (130V/260V), off-state voltage (90V/180V), on-state voltage (4V), peak pulse current (250A at 8/20µs), hold current (150 mA), element count (2), and package type (3-SIP TO-220 Modified).

Q: Is the P2202ABL the only substitute for the P2202AB?

A: Based on the provided data, the P2202ABL is the identified direct substitute. Any additional equivalents would require matching all specified electrical and mechanical parameters.
