P3002AA Equivalent & Substitute Parts

Part Overview

The P3002AA is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. under the SIDACtor® series. This component is designed for overvoltage protection applications, featuring dual-element configuration with 140V/280V off-state voltage ratings and 150A peak pulse current capability in a 3-SIP TO-220 Modified package.

The P3002AA is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Substitute Part Grouping Explanation

Substitute parts for the P3002AA are qualified based on electrical and mechanical parameter equivalence:

Electrical Parameters (Must Match):

• Voltage - Breakover: 180V, 360V
• Voltage - Off State: 140V, 280V
• Voltage - On State: 4 V
• Current - Peak Pulse (8/20µs): 150 A
• Current - Peak Pulse (10/1000µs): 45 A
• Current - Hold (Ih): 150 mA
• Number of Elements: 2
• Capacitance: 25pF, 40pF

Mechanical Parameters (Must Match):

• Package / Case: 3-SIP
• Mounting Type: Through Hole
• Supplier Device Package: TO-220 Modified

Both substitute parts (P3002AAL and P3002AALRP) meet all electrical and mechanical requirements. The primary differences are product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

Both P3002AAL and P3002AALRP are direct electrical and mechanical equivalents to the obsolete P3002AA. Selection between these two active alternatives depends on procurement and assembly requirements:

P3002AAL (Bulk Packaging): Suitable for applications requiring individual component handling or lower-volume procurement. This part maintains active product status with ROHS3 compliance and REACH unaffected certification.

P3002AALRP (Tape & Reel Packaging): Optimized for automated assembly processes and high-volume production environments. This part also maintains active product status with ROHS3 compliance and REACH unaffected certification.

Both substitute parts provide improved regulatory compliance compared to the original P3002AA, which is RoHS non-compliant. The electrical performance and mechanical form factor are identical across all three part numbers.

Frequently Asked Questions (FAQ)

Q: Can P3002AAL or P3002AALRP be used as direct replacements for P3002AA?

A: Yes. Both parts are electrically and mechanically equivalent. They feature identical voltage ratings (140V/280V off-state, 180V/360V breakover), current ratings (150A peak pulse at 8/20µs), on-state voltage (4V), and package configuration (3-SIP TO-220 Modified). The primary differences are product status (active vs. obsolete) and regulatory compliance (ROHS3 compliant vs. non-compliant).

Q: What is the difference between P3002AAL and P3002AALRP?

A: The electrical and mechanical specifications are identical. The difference is packaging format: P3002AAL is supplied in bulk packaging, while P3002AALRP is supplied in Tape & Reel format. Selection depends on assembly method and procurement volume requirements.

Q: Are there any compliance differences between the substitute parts and the original P3002AA?

A: Yes. Both P3002AAL and P3002AALRP are ROHS3 compliant and REACH unaffected, whereas the original P3002AA is RoHS non-compliant. All three parts share the same ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

Q: Can these parts be used interchangeably in PCB assembly?

A: P3002AAL and P3002AALRP can be used interchangeably from an electrical and mechanical standpoint. However, assembly process compatibility depends on whether your production line uses manual (bulk) or automated (tape & reel) component placement. Both parts use the same 3-SIP TO-220 Modified through-hole package.

Q: Why is the original P3002AA listed as obsolete?

A: The P3002AA is classified as obsolete by the manufacturer. The active alternatives P3002AAL and P3002AALRP provide equivalent functionality with improved regulatory compliance and continued manufacturer support.
