P2600SCRP Equivalent & Substitute Parts

Part Overview

The P2600SCRP is a 220V off-state thyristor TVS (Transient Voltage Suppressor) manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA (SMB) surface mount package. This component is designed for transient voltage protection applications requiring 400A peak pulse current capability at 8/20µs waveform.

The P2600SCRP is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure availability for new production runs and field replacements where the original component is no longer procurable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of TVS thyristor components is determined by electrical and mechanical compatibility within the following criteria:

Electrical Parameters (Critical for Substitution):

• Voltage - Off State: Must match 220V
• Voltage - Breakover: Must be within acceptable tolerance range (290V–300V)
• Voltage - On State: Must be compatible with circuit requirements (3V–4V acceptable)
• Current - Peak Pulse (8/20µs): Must meet or exceed application requirements
• Current - Hold (Ih): Must match 150mA
• Number of Elements: Must be 1

Mechanical Parameters (Required for Compatibility):

• Package / Case: Must be DO-214AA, SMB
• Mounting Type: Must be Surface Mount

Compliance & Availability:

• Product Status: Active status preferred for new designs; obsolete parts require substitution
• RoHS Status: ROHS3 compliance recommended for regulatory alignment

All substitute parts listed below satisfy these criteria and are electrically and mechanically interchangeable with the P2600SCRP within the specified parameter ranges.

Engineering Selection Recommendations

P2600SCLRP (Littelfuse Inc.)

This part is the direct equivalent to P2600SCRP with identical electrical specifications. It maintains the same 400A peak pulse current rating, 220V off-state voltage, and 80pF capacitance. The primary difference is product status: P2600SCLRP is active and ROHS3 compliant, whereas P2600SCRP is obsolete and non-compliant. P2600SCLRP is supplied in Tape & Reel packaging. This is the preferred substitute for direct replacement in new designs and production.

SMTPA220 (STMicroelectronics)

This part operates at the same 220V off-state voltage with a breakover voltage of 293V, within the acceptable range. However, the peak pulse current rating is 150A (8/20µs), which is lower than the P2600SCRP specification of 400A. The capacitance is also reduced to 25pF. SMTPA220 is suitable only for applications where the lower current rating is acceptable. This part is ROHS3 compliant and active.

TISP4290T3BJR-S (Bourns Inc.)

This part operates at 220V off-state voltage with a breakover voltage of 290V and an on-state voltage of 3V. The peak pulse current rating is 250A (8/20µs), which is lower than the P2600SCRP specification of 400A. The capacitance is 52pF. TISP4290T3BJR-S is suitable for applications where the 250A current rating meets system requirements. This part is ROHS3 compliant and active, though REACH status is affected.

Frequently Asked Questions (FAQ)

Q: Can P2600SCLRP be used as a direct replacement for P2600SCRP?

A: Yes. P2600SCLRP is electrically and mechanically identical to P2600SCRP. Both parts share the same 220V off-state voltage, 300V breakover voltage, 400A peak pulse current (8/20µs), 150mA hold current, 80pF capacitance, and DO-214AA SMB package. The primary difference is that P2600SCLRP is active and ROHS3 compliant, making it the recommended substitute for the obsolete P2600SCRP.

Q: Can SMTPA220 replace P2600SCRP in all applications?

A: SMTPA220 can replace P2600SCRP only in applications where the lower peak pulse current rating of 150A is acceptable. The P2600SCRP is rated for 400A (8/20µs), while SMTPA220 is rated for 150A. Both parts maintain the same 220V off-state voltage and 150mA hold current. Verify that your circuit design does not require the higher current capability before substituting.

Q: Can TISP4290T3BJR-S replace P2600SCRP in all applications?

A: TISP4290T3BJR-S can replace P2600SCRP only in applications where the lower peak pulse current rating of 250A is acceptable. The P2600SCRP is rated for 400A (8/20µs), while TISP4290T3BJR-S is rated for 250A. Both parts maintain the same 220V off-state voltage and 150mA hold current. Verify that your circuit design does not require the higher current capability before substituting.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts listed (P2600SCLRP, SMTPA220, and TISP4290T3BJR-S) use the DO-214AA (SMB) surface mount package. They are mechanically compatible and can be used on the same PCB layout without modification.

Q: What is the difference between the packaging options?

A: P2600SCLRP is supplied in Tape & Reel (TR) format. SMTPA220 is supplied in Cut Tape (CT) and Digi-Reel® format. TISP4290T3BJR-S is supplied in Tape & Reel (TR) format. The packaging format affects handling and automated assembly processes but does not affect electrical or mechanical compatibility.

Q: Are all substitute parts RoHS compliant?

A: P2600SCLRP, SMTPA220, and TISP4290T3BJR-S are all ROHS3 compliant. The original P2600SCRP is RoHS non-compliant. For new designs and applications subject to RoHS regulations, use one of the compliant substitute parts.
