Substitute Part Grouping Explanation

Substitution for the P0300ECMCL is determined by equivalence in the following critical parameters:

• Voltage - Off State: 25V
• Voltage - Breakover: 40V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 50mA
• Package / Case: TO-226-2, TO-92-2
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

The P0300ECL meets all substitution criteria and is classified as a direct equivalent part within the SIDACtor® series.

Parameter Comparison

Engineering Selection Recommendations

Both P0300ECMCL and P0300ECL are active production parts with identical electrical performance specifications and mechanical compatibility. Both components carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts may be based on application-specific capacitance requirements, as the P0300ECL exhibits higher capacitance (250pF versus 45pF). Inventory availability should also be considered in procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can P0300ECL replace P0300ECMCL in existing designs? A: Yes. Both parts share identical voltage ratings, current ratings, hold current specifications, and package configurations. They are electrically and mechanically interchangeable for the specified electrical parameters.
