P2600GALRP Equivalent & Substitute Parts

Part Overview

The P2600GALRP is a 220V off-state thyristor-based transient voltage suppressor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for overvoltage protection applications requiring fast response to transient events. The part is currently in Active product status with 1165 units available in inventory.

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when design requirements allow for alternative specifications within acceptable electrical and mechanical parameters. The TPA220 from STMicroelectronics represents a qualified alternative that maintains compatibility with the DO-204AC package and core voltage specifications while offering different current handling characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2600GALRP is determined by the following critical parameters:

• Off-State Voltage: Must be 220V to maintain circuit protection threshold
• Breakover Voltage: Must be within acceptable range (293V–300V) to ensure consistent triggering behavior
• On-State Voltage: Must be 5V or lower to minimize voltage drop during conduction
• Hold Current (Ih): Must be 150 mA to sustain latching after triggering
• Package / Case: Must be DO-204AC, DO-15, Axial for mechanical and thermal compatibility
• Mounting Type: Must be Through Hole for PCB integration compatibility
• Number of Elements: Must be 1 for single-channel protection

The TPA220 meets all these core substitution criteria. Peak pulse current specifications may vary based on different measurement standards (10/1000µs vs. 8/20µs), but both parts maintain the same hold current and voltage characteristics necessary for functional equivalence in protection circuits.

Engineering Selection Recommendations

P2600GALRP (Primary Selection)

The P2600GALRP is recommended for new designs and applications where component availability is not constrained. This part maintains Active product status and has 1165 units in current inventory. Both the P2600GALRP and TPA220 are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements.

TPA220 (Substitute Selection)

The TPA220 is qualified as a direct substitute when P2600GALRP availability is limited or when design flexibility permits. The TPA220 carries Last Time Buy status, indicating reduced future availability. The substitute maintains electrical compatibility across all critical parameters: identical off-state voltage (220V), hold current (150mA), package configuration (DO-204AC), and mounting type (Through Hole). The breakover voltage differential (293V vs. 300V) and peak pulse current increase (50A vs. 45A at 10/1000µs) remain within acceptable operating margins for transient suppression applications.

Both parts satisfy identical compliance certifications (ROHS3, REACH unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can the TPA220 be used as a direct replacement for the P2600GALRP in existing designs?

A: Yes. Both parts share identical off-state voltage (220V), hold current (150mA), package type (DO-204AC), and mounting configuration (Through Hole). The 7V difference in breakover voltage (293V vs. 300V) and the higher peak pulse current rating of the TPA220 (50A vs. 45A) do not prevent functional substitution in transient suppression circuits.

Q: What is the significance of the different peak pulse current measurements (10/1000µs vs. 8/20µs)?

A: These represent different test pulse standards. The P2600GALRP specifies 45A at 10/1000µs, while the TPA220 specifies 50A at 8/20µs and 50A at 10/1000µs. Both measurements characterize the component's ability to handle transient energy. The TPA220's higher rating provides additional margin in protection applications.

Q: Are there package compatibility concerns when substituting?

A: No. Both the P2600GALRP and TPA220 use the DO-204AC (DO-15) axial package with Through Hole mounting. PCB layout and thermal design remain unchanged during substitution.

Q: What is the product status difference between these parts?

A: The P2600GALRP is Active with ongoing production and inventory support. The TPA220 is Last Time Buy, indicating STMicroelectronics has announced end-of-production. For new designs requiring long-term supply, the P2600GALRP is the preferred choice.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the P2600GALRP and TPA220 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8541.30.0080.
