P3002AC Equivalent & Substitute Parts

Part Overview

The P3002AC is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for overvoltage protection applications requiring 140V/280V off-state voltage ratings with 400A peak pulse current capability. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Direct substitutes maintain identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3002AC is determined by strict equivalence across all electrical parameters: off-state voltage (140V, 280V), breakover voltage (180V, 360V), on-state voltage (4V), peak pulse current ratings (400A at 8/20µs and 100A at 10/1000µs), hold current (150mA), element count (2), capacitance values (55pF, 95pF), and mechanical form factor (3-SIP, TO-220 Modified through-hole package). The identified substitutes P3002ACL and P3002ACLRP maintain complete electrical and mechanical compatibility with the original P3002AC specification. Differentiation between substitutes is based solely on packaging format (bulk versus tape & reel) and product status (active versus obsolete), with no variation in functional performance or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both P3002ACL and P3002ACLRP provide direct functional equivalence to the obsolete P3002AC with identical electrical performance across all specified parameters. Selection between the two active substitutes depends on procurement and assembly requirements: P3002ACL is supplied in bulk packaging suitable for manual assembly or small-volume applications, while P3002ACLRP is supplied in tape & reel format optimized for automated pick-and-place assembly processes. Both substitutes carry ROHS3 compliance and REACH unaffected status, providing improved regulatory alignment compared to the non-compliant original part. For new designs and production transitions, either substitute provides equivalent performance with enhanced product lifecycle support due to active status.

Frequently Asked Questions (FAQ)

Q: Can P3002ACL or P3002ACLRP be used as direct replacements for P3002AC in existing designs?

A: Yes. Both substitutes maintain complete electrical equivalence across all specified parameters including voltage ratings, current ratings, capacitance, and element count. The 3-SIP TO-220 Modified package geometry is identical, enabling direct board-level substitution without circuit modification.

Q: What is the difference between P3002ACL and P3002ACLRP?

A: The parts are electrically and mechanically identical. The difference is packaging format: P3002ACL is supplied in bulk packaging, while P3002ACLRP is supplied in tape & reel format. Selection depends on assembly method and volume requirements.

Q: Why is the original P3002AC marked as obsolete?

A: Product obsolescence reflects end-of-life status from the manufacturer. The active substitutes P3002ACL and P3002ACLRP provide continued access to equivalent functionality with improved compliance certifications and ongoing product support.

Q: Are there compliance differences between P3002AC and its substitutes?

A: Yes. P3002AC is RoHS non-compliant, while both P3002ACL and P3002ACLRP are ROHS3 compliant and REACH unaffected. For applications subject to RoHS or REACH requirements, the substitutes are the appropriate selection.

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

A: P3002ACLRP in tape & reel format is optimized for automated pick-and-place assembly. P3002ACL in bulk format is suitable for manual or semi-automated processes. Both are mechanically compatible with standard through-hole assembly equipment.
