P0220SAMCLRP Equivalent & Substitute Parts

Part Overview

The P0220SAMCLRP is a 15V off-state thyristor transient voltage suppressor (TVS) manufactured by Littelfuse Inc. in the SIDACtor® series. This surface-mount component in DO-214AA (SMB) packaging is designed for transient overvoltage protection applications requiring 150 A peak pulse current capability. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when electrical and mechanical parameters remain within the specified tolerance range for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0220SAMCLRP is determined by equivalence across the following critical parameters:

• Voltage ratings (breakover, off-state, and on-state) must be identical
• Peak pulse current capability (both 8/20µs and 10/1000µs waveforms) must be identical
• Hold current (Ih) must be identical
• Package type (DO-214AA, SMB) must be identical
• Mounting configuration (surface mount) must be identical
• Number of elements must be identical

The P0220SALRP meets all substitution criteria. Both parts share identical voltage specifications, current ratings, hold current, and mechanical packaging. The capacitance parameter differs between the two parts (50pF vs. 150pF); however, this variation remains within the allowable range for TVS thyristor substitution in this category and does not affect the core functional equivalence for transient suppression applications.

Parameter Comparison

Engineering Selection Recommendations

Both P0220SAMCLRP and P0220SALRP are active production parts with identical compliance certifications (RoHS3, REACH Unaffected). Selection between these parts is based on application-specific capacitance requirements. The P0220SAMCLRP features 50pF capacitance, while the P0220SALRP provides 150pF capacitance. All other electrical and mechanical specifications are equivalent. Component selection should be determined by circuit design requirements for transient suppression performance and frequency response characteristics.

Frequently Asked Questions (FAQ)

Q: Can P0220SALRP replace P0220SAMCLRP in all applications?

A: Both parts are electrically equivalent across voltage ratings, current ratings, and hold current specifications. The capacitance difference (50pF vs. 150pF) may affect high-frequency circuit behavior. Application-specific circuit analysis is required to confirm suitability.

Q: Are the package dimensions identical between these parts?

A: Both parts use DO-214AA (SMB) surface-mount packaging with identical mechanical specifications and PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both P0220SAMCLRP and P0220SALRP are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the primary difference between these substitute parts?

A: The capacitance parameter differs: P0220SAMCLRP is rated at 50pF, while P0220SALRP is rated at 150pF. All other specifications are identical.

Q: Are both parts currently in production?

A: Yes. Both parts maintain active product status with Littelfuse Inc. and are available in stock quantities.
