Key Parameters

Substitute Part Grouping Explanation

Substitution of the 30KPA260 is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 260V
• Voltage - Clamping (Max) @ Ipp: Must remain within acceptable operating range
• Current - Peak Pulse (10/1000µs): 72.8A
• Power - Peak Pulse: 30000W (30kW)
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C to 175°C (TJ)

The 30KPA260A qualifies as a direct substitute based on matching all critical parameters within the allowed tolerance band for this product category.

Parameter Comparison

Engineering Selection Recommendations

The 30KPA260A is the qualified substitute for the obsolete 30KPA260. Both components maintain identical reverse standoff voltage, peak pulse current, and peak pulse power ratings. The 30KPA260A offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts are ROHS3 compliant and operate across the same temperature range, supporting direct replacement in existing designs. The 30KPA260A features a lower maximum clamping voltage (416V versus 436.8V), which provides improved transient suppression performance while remaining within acceptable operating parameters for general-purpose TVS applications.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA260A be used as a direct replacement for the 30KPA260?

A: Yes. Both components share identical reverse standoff voltage (260V), peak pulse current (72.8A), peak pulse power (30kW), operating temperature range (-55°C to 175°C), and P600 axial package configuration. The 30KPA260A is the designated substitute.

Q: What is the difference in clamping voltage between these parts?

A: The 30KPA260 has a maximum clamping voltage of 436.8V, while the 30KPA260A is rated at 416V. The lower clamping voltage of the substitute provides enhanced transient suppression performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the 30KPA260 and 30KPA260A are ROHS3 compliant.

Q: Why is the 30KPA260 listed as obsolete?

A: The 30KPA260 has been discontinued by Littelfuse Inc. The 30KPA260A, manufactured by MDE Semiconductor Inc., is the active equivalent available for new designs and ongoing system support.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both components use identical P600 axial through-hole packaging, allowing direct PCB footprint compatibility without design modification.
