Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2703AB60 is determined by electrical and mechanical parameter equivalence across the following criteria:

• Voltage ratings: Breakover voltage of 300V, off-state voltage of 230V, and on-state voltage of 8V must remain constant
• Current specifications: Peak pulse current (8/20µs) of 250A and (10/1000µs) of 80A, with hold current of 150mA
• Element configuration: Three integrated elements required
• Capacitance values: 50pF and 75pF specifications
• Package compatibility: 3-SIP through-hole configuration in TO-220 Modified supplier package

Parts meeting all these parameters are considered direct functional equivalents suitable for replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The P2703ABL60 is the direct equivalent substitute for the obsolete P2703AB60. Both components share identical electrical specifications and package configurations, ensuring functional interchangeability without circuit modification.

The primary distinction between these parts is product status and regulatory compliance. The P2703ABL60 maintains active product status with Littelfuse Inc., ensuring continued availability and supply chain reliability. Additionally, the P2703ABL60 is ROHS3 compliant, whereas the P2703AB60 is RoHS non-compliant. For applications subject to RoHS requirements or environmental regulations, the P2703ABL60 is the appropriate selection.

Both components carry identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications, indicating equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the P2703ABL60 replace the P2703AB60 in existing designs?

A: Yes. The P2703ABL60 is electrically and mechanically identical to the P2703AB60 across all specified parameters, including voltage ratings, current handling, element count, capacitance values, and 3-SIP through-hole package configuration. No circuit redesign is required.

Q: What is the primary reason to transition from P2703AB60 to P2703ABL60?

A: The P2703AB60 is classified as obsolete, while the P2703ABL60 maintains active product status. This ensures long-term availability, supply chain continuity, and access to current manufacturing processes. Additionally, the P2703ABL60 is ROHS3 compliant, meeting modern environmental and regulatory standards.

Q: Are there packaging differences between these parts?

A: Both components use identical 3-SIP through-hole packages in TO-220 Modified supplier configuration. The only packaging distinction is that P2703AB60 is supplied in standard packaging, while P2703ABL60 is supplied in bulk packaging. This does not affect electrical or mechanical compatibility.

Q: Do these parts have the same regulatory classifications?

A: Yes. Both the P2703AB60 and P2703ABL60 share identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications. The difference in RoHS status (non-compliant versus ROHS3 compliant) reflects manufacturing process updates in the active P2703ABL60 variant.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by matching voltage specifications (300V breakover, 230V off-state, 8V on-state), current ratings (250A peak pulse at 8/20µs, 80A at 10/1000µs, 150mA hold current), three-element configuration, capacitance values (50pF and 75pF), and 3-SIP through-hole package format.
