P2602SALRP Equivalent & Substitute Parts

Part Overview

The P2602SALRP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in 220V applications. This Surface Mount Device (SMD) component operates in the DO-214AA package and is classified as Active product status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range for this TVS thyristor category.

Substitute Part Grouping Explanation

Substitution of TVS thyristor components is determined by electrical and mechanical compatibility within defined tolerance ranges. The P2602SALRP can be substituted with the SMTPA220 based on the following criteria:

Critical Substitution Parameters:

• Off-State Voltage: 220V (exact match required)
• Peak Pulse Current (8/20µs): 150A (exact match required)
• Package / Case: DO-214AA, SMB (mechanical compatibility required)
• Mounting Type: Surface Mount (assembly compatibility required)
• RoHS and REACH Compliance: Both parts meet ROHS3 and REACH Unaffected status

Allowable Variation Parameters:

• Voltage - Breakover: 293V to 300V range (within acceptable operating margin)
• Current - Peak Pulse (10/1000µs): 45A to 50A range (within pulse profile tolerance)
• Current - Hold (Ih): 120mA to 150mA range (within holding current tolerance)
• Number of Elements: Single vs. dual element configuration (functional equivalence in application context)
• Capacitance: 25pF (matched specification)

Parameter Comparison

Engineering Selection Recommendations

Both the P2602SALRP and SMTPA220 maintain Active product status and full compliance with ROHS3 and REACH regulations. Selection between these components should be based on:

Availability and Lead Time: The SMTPA220 (STMicroelectronics) currently has 3700 units in stock versus 2300 units for the P2602SALRP (Littelfuse). Packaging format differs: SMTPA220 is supplied in Cut Tape (CT) & Digi-Reel® format, while P2602SALRP is supplied in Tape & Reel (TR) format.

Electrical Performance: Both devices meet the 220V off-state voltage and 150A peak pulse current requirements. The SMTPA220 exhibits a slightly lower breakover voltage (293V vs. 300V) and marginally higher holding current (150mA vs. 120mA), both within acceptable operational margins for 220V protection applications.

Regulatory Compliance: Both components satisfy identical compliance requirements (ROHS3, REACH Unaffected, EAR99 ECCN, 8541.30.0080 HTSUS code), ensuring interchangeability in regulated supply chains.

Frequently Asked Questions (FAQ)

Q: Can the SMTPA220 directly replace the P2602SALRP in existing designs?

A: Yes. Both components share identical off-state voltage (220V), peak pulse current rating (150A), package type (DO-214AA, SMB), and mounting method (Surface Mount). Electrical parameters fall within acceptable tolerance ranges for TVS thyristor substitution.

Q: What is the significance of the different number of elements (2 vs. 1)?

A: The P2602SALRP contains two internal elements (TwinChip™ configuration), while the SMTPA220 contains one element. Both configurations deliver equivalent 150A peak pulse current performance in the same package footprint. Element count does not affect PCB assembly compatibility or electrical substitution validity.

Q: How do the breakover voltage differences (300V vs. 293V) affect circuit protection?

A: The 7V difference in breakover voltage falls within standard design margins for 220V off-state applications. Both devices trigger protection within acceptable thresholds for transient suppression. This variation does not compromise protection effectiveness in equivalent circuit topologies.

Q: Are there packaging format considerations when substituting these parts?

A: Yes. The P2602SALRP is supplied in Tape & Reel (TR) format, while the SMTPA220 is supplied in Cut Tape (CT) & Digi-Reel® format. Verify that your assembly equipment and procurement workflow accommodate the substitute packaging format before implementation.

Q: Do both parts meet the same regulatory and compliance standards?

A: Confirmed. Both the P2602SALRP and SMTPA220 are ROHS3 Compliant, REACH Unaffected, classified under EAR99 ECCN, and share the same HTSUS code (8541.30.0080). Regulatory substitution is valid for controlled supply chain applications.
