P0220SARP Equivalent & Substitute Parts

Part Overview

The P0220SARP is a 15V off-state TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA (SMB) surface mount package. This component is designed for transient voltage suppression applications requiring 150 A peak pulse current capability at 8/20µs pulse width.

The P0220SARP is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, maintenance, and system redesigns where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

The P0220SALRP qualifies as a direct substitute for the P0220SARP based on the following electrical and mechanical parameters:

• Identical voltage ratings: 32V breakover, 15V off-state, 4V on-state
• Identical current specifications: 150 A peak pulse (8/20µs), 45 A peak pulse (10/1000µs), 50 mA hold current
• Identical capacitance: 150 pF
• Identical package and mounting: DO-214AA (SMB) surface mount
• Single element configuration

The primary distinction between these parts is packaging format and product status. The P0220SALRP is supplied in Tape & Reel (TR) format and maintains Active product status, whereas the P0220SARP is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The P0220SALRP is the direct substitute for the P0220SARP. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in transient voltage suppression applications.

The P0220SALRP offers two significant advantages:

1. Active product status ensures continued availability and supply chain support
2. ROHS3 compliance meets current environmental and regulatory requirements, whereas the P0220SARP is RoHS non-compliant

For new designs or production transitions, the P0220SALRP is the appropriate selection. The Tape & Reel packaging format is standard for high-volume manufacturing and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the P0220SALRP be used as a direct replacement for the P0220SARP in existing designs?

A: Yes. The P0220SALRP is electrically and mechanically identical to the P0220SARP. All voltage ratings, current specifications, capacitance values, and package dimensions are equivalent. The components are pin-compatible and functionally interchangeable.

Q: What is the difference between the P0220SARP and P0220SALRP?

A: The primary differences are packaging format and product status. The P0220SALRP is supplied in Tape & Reel format and maintains Active status, while the P0220SARP is obsolete. Additionally, the P0220SALRP is ROHS3 compliant, whereas the P0220SARP is RoHS non-compliant.

Q: Why is the P0220SARP classified as obsolete?

A: Littelfuse Inc. has discontinued the P0220SARP. The P0220SALRP serves as the active replacement part for ongoing production and new applications.

Q: Are there any performance differences between these parts?

A: No. Both components deliver identical electrical performance: 32V breakover voltage, 15V off-state voltage, 4V on-state voltage, 150 A peak pulse current (8/20µs), 45 A peak pulse current (10/1000µs), and 50 mA hold current.

Q: What packaging formats are available?

A: The P0220SARP was supplied in bulk packaging. The P0220SALRP is supplied in Tape & Reel (TR) format, which is standard for automated assembly and high-volume production environments.

Q: Does the P0220SALRP meet RoHS requirements?

A: Yes. The P0220SALRP is ROHS3 compliant. The obsolete P0220SARP is RoHS non-compliant.
