P3002ACMC Equivalent & Substitute Parts

Part Overview

The P3002ACMC is a TVS thyristor from Littelfuse Inc.'s SIDACtor® series, designed for transient voltage suppression applications. It features 140V/280V off-state voltage ratings with 400A peak pulse current capability in a 3-SIP TO-220 Modified package. The P3002ACMC 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 P3002ACMC is determined by electrical and mechanical parameter equivalence across the following criteria:

• Voltage ratings (breakover and off-state) must match exactly: 180V/360V breakover and 140V/280V off-state
• Peak pulse current capability must meet or exceed 400A (8/20µs) and 100A (10/1000µs)
• On-state voltage must remain at 4V
• Hold current (Ih) must be 150 mA
• Capacitance range must fall within 35pF to 55pF
• Package configuration must be 3-SIP with Through Hole mounting
• Supplier device package must be TO-220 Modified

The P3002ACMCL meets all these criteria and serves as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P3002ACMCL is the direct equivalent for the obsolete P3002ACMC. All electrical parameters and mechanical specifications are identical. The primary distinction is product status and compliance posture: the P3002ACMCL is active and ROHS3 compliant, whereas the P3002ACMC is obsolete and RoHS non-compliant. For new designs or ongoing procurement, the P3002ACMCL is the appropriate selection. Both parts share identical packaging (TO-220 Modified, 3-SIP) and mounting methodology (Through Hole), ensuring direct board-level compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the P3002ACMCL directly replace the P3002ACMC in existing designs?

A: Yes. The P3002ACMCL is electrically and mechanically identical to the P3002ACMC. All voltage ratings, current specifications, and package dimensions match exactly. No circuit redesign or PCB modification is required.

Q: What is the difference between these two part numbers?

A: The P3002ACMCL is the active production equivalent of the obsolete P3002ACMC. The suffix "L" indicates the active variant. The P3002ACMCL also carries ROHS3 compliance certification, whereas the P3002ACMC does not.

Q: Are there any packaging differences?

A: No. Both parts use identical 3-SIP TO-220 Modified packaging with Through Hole mounting. They are pin-for-pin and footprint-compatible.

Q: Why is the P3002ACMC listed as obsolete?

A: The P3002ACMC has been superseded by the P3002ACMCL in Littelfuse's product portfolio. The P3002ACMCL provides the same functionality with updated compliance certifications.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching voltage ratings (180V/360V breakover, 140V/280V off-state), peak pulse current (400A at 8/20µs), on-state voltage (4V), hold current (150 mA), and capacitance range (35pF–55pF). The P3002ACMCL meets all these criteria.
