P0721CA2 Equivalent & Substitute Parts

Part Overview

The P0721CA2 is a Transient Voltage Suppressor (TVS) device manufactured by Littelfuse Inc., designed for circuit protection in SLIC applications. This mixed-technology TVS operates at 88V clamping voltage and features dual circuits in a compact DO-214AA surface mount package. The P0721CA2 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0721CA2 is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: 88V (exact match required)
• Technology: Mixed Technology (exact match required)
• Number of Circuits: 2 (exact match required)
• Package / Case: DO-214AA, SMB (3 Leads), Compak (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Applications: SLIC (exact match required)
• Series: TwinSLIC™ (exact match required)

The P0721CA2LRP meets all substitution criteria as a direct equivalent. The primary distinction between these parts is packaging format and product status, not electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The P0721CA2LRP is the direct active equivalent for the obsolete P0721CA2. Both parts share identical electrical specifications, clamping voltage, circuit configuration, and mechanical package dimensions. Selection between these parts is determined by procurement requirements and regulatory compliance needs.

The P0721CA2LRP offers the advantage of active product status, ensuring continued manufacturer support and availability. Additionally, the P0721CA2LRP meets ROHS3 compliance requirements, whereas the P0721CA2 is RoHS non-compliant. For new designs or applications requiring RoHS compliance, the P0721CA2LRP is the appropriate selection.

The packaging difference (bulk versus Tape & Reel) reflects standard industry practice for active versus obsolete product lines and does not affect electrical or mechanical compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can P0721CA2LRP be used as a direct replacement for P0721CA2?

A: Yes. The P0721CA2LRP is a direct equivalent. Both parts feature identical 88V clamping voltage, mixed-technology design, dual-circuit configuration, and DO-214AA surface mount package. Electrical and mechanical compatibility is complete.

Q: What is the primary difference between P0721CA2 and P0721CA2LRP?

A: The P0721CA2 is obsolete with bulk packaging, while P0721CA2LRP is an active product supplied in Tape & Reel format. The P0721CA2LRP also meets ROHS3 compliance standards. Electrical specifications and package dimensions are identical.

Q: Does the Tape & Reel packaging of P0721CA2LRP affect circuit performance?

A: No. Tape & Reel packaging is a distribution format only and does not affect electrical performance, clamping characteristics, or mechanical fit in the circuit. The component itself is identical.

Q: Is the P0721CA2LRP suitable for new designs?

A: Yes. The P0721CA2LRP is the recommended choice for new designs due to its active product status, ROHS3 compliance, and assured long-term availability from Littelfuse Inc.

Q: Are there any compliance differences between these parts?

A: The P0721CA2LRP meets ROHS3 compliance requirements, while the P0721CA2 is RoHS non-compliant. For applications requiring RoHS compliance, the P0721CA2LRP is the appropriate selection.
