Substitute Part Grouping Explanation

The P3403ABL60 qualifies as a direct substitute for the P3403AB60 based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Identical voltage ratings: 400V breakover, 300V off-state, 8V on-state
• Identical current specifications: 250A peak pulse (8/20µs), 80A peak pulse (10/1000µs), 150mA hold current
• Identical element count: 3 elements
• Identical capacitance values: 45pF, 65pF
• Identical package configuration: 3-SIP, TO-220 Modified, through-hole mounting
• Same manufacturer: Littelfuse Inc., SIDACtor® series

The P3403ABL60 differs from the P3403AB60 in product status (active vs. obsolete) and packaging format (bulk vs. standard), with improved RoHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

The P3403ABL60 is the appropriate substitute for the obsolete P3403AB60. Both components maintain identical electrical performance and mechanical compatibility. The P3403ABL60 offers the advantage of active product status, ensuring continued availability and manufacturer support. Additionally, the P3403ABL60 meets ROHS3 compliance requirements, whereas the P3403AB60 is non-compliant. For applications subject to RoHS regulations or requiring long-term component availability, the P3403ABL60 is the preferred selection. Both parts share identical ECCN and HTSUS classifications, maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the P3403ABL60 be used as a direct replacement for the P3403AB60?

A: Yes. The P3403ABL60 is electrically and mechanically identical to the P3403AB60. All voltage ratings, current specifications, element count, capacitance values, and package configurations match exactly. The components are pin-compatible and functionally equivalent.

Q: What is the primary difference between these two parts?

A: The P3403AB60 is obsolete, while the P3403ABL60 is active. The P3403ABL60 also provides ROHS3 compliance, whereas the P3403AB60 is non-compliant. Packaging format differs (bulk vs. standard), but electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the P3403ABL60 for the P3403AB60?

A: No compatibility concerns exist. Both parts use the 3-SIP TO-220 Modified through-hole package with identical pin configurations and mounting requirements. PCB layouts and thermal management designs require no modification.

Q: Does the P3403ABL60 meet current regulatory requirements?

A: Yes. The P3403ABL60 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The P3403AB60 does not meet these requirements.

Q: What is the moisture sensitivity level for these components?

A: Both the P3403AB60 and P3403ABL60 have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
