P0300EAMC Equivalent & Substitute Parts

Part Overview

The P0300EAMC is a 25V off-state TVS thyristor from Littelfuse Inc.'s SIDACtor® series, designed for transient voltage suppression applications. This component features a 150 A peak pulse current rating (8/20µs) and is housed in a TO-226-2 package for through-hole mounting. The P0300EAMC 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 P0300EAMC is determined by electrical and mechanical parameter matching within the TVS thyristor category. The critical parameters for substitution are:

• Voltage - Off State: 25V
• Voltage - Breakover: 40V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 150 A
• Current - Peak Pulse (10/1000µs): 45 A
• Current - Hold (Ih): 50 mA
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole

The P0300EAMCL meets all these electrical and mechanical requirements and serves as a direct substitute for the obsolete P0300EAMC.

Parameter Comparison

Engineering Selection Recommendations

The P0300EAMCL is the direct substitute for the obsolete P0300EAMC. Both components are manufactured by Littelfuse Inc. and share identical electrical specifications and package configurations. The P0300EAMCL is currently in active production status, ensuring long-term availability and supply chain continuity.

The P0300EAMCL offers improved compliance posture, meeting ROHS3 requirements compared to the non-compliant status of the P0300EAMC. Both components maintain the same moisture sensitivity level and are suitable for through-hole PCB assembly applications requiring 25V off-state TVS thyristor protection.

Frequently Asked Questions (FAQ)

Q: Can the P0300EAMCL directly replace the P0300EAMC in existing designs?

A: Yes. The P0300EAMCL is electrically and mechanically identical to the P0300EAMC. All voltage ratings, current specifications, and package dimensions are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between the P0300EAMC and P0300EAMCL?

A: The primary differences are product status and RoHS compliance. The P0300EAMC is obsolete and RoHS non-compliant, while the P0300EAMCL is active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The P0300EAMC is supplied in standard packaging, while the P0300EAMCL is supplied in bulk packaging. Both use the same TO-226-2 / TO-92-2 (TO-226AC) package for through-hole mounting. Bulk packaging does not affect component performance or compatibility.

Q: Why should I transition from P0300EAMC to P0300EAMCL?

A: The P0300EAMC is obsolete and subject to discontinuation. The P0300EAMCL ensures continued availability, supply chain reliability, and compliance with current environmental regulations (ROHS3).

Q: Are the electrical characteristics identical between these TVS thyristors?

A: Yes. Both components have identical voltage ratings (25V off-state, 40V breakover, 4V on-state), peak pulse current ratings (150 A at 8/20µs, 45 A at 10/1000µs), hold current (50 mA), and capacitance (140 pF).
