P3100ECMCL Equivalent & Substitute Parts

Part Overview

The P3100ECMCL is a 275V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling capability in a compact TO-226-2 package. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints or application-specific packaging preferences.

Substitute Part Grouping Explanation

Substitution of the P3100ECMCL with the P3100ECL is permissible based on the following criteria:

Electrical Equivalence Parameters:

• Voltage - Off State: 275V (identical)
• Voltage - Breakover: 350V (identical)
• Voltage - On State: 4V (identical)
• Current - Peak Pulse (8/20µs): 400A (identical)
• Current - Peak Pulse (10/1000µs): 100A (identical)
• Current - Hold (Ih): 150mA (identical)
• Number of Elements: 1 (identical)

Mechanical Compatibility Parameters:

• Package / Case: TO-226-2, TO-92-2 (TO-226AC) (identical)
• Mounting Type: Through Hole (identical)

Compliance & Status:

• Series: SIDACtor® (identical)
• Product Status: Active (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• REACH Status: REACH Unaffected (identical)

The P3100ECL differs only in capacitance (70pF versus 45pF), which remains within acceptable tolerance for TVS thyristor applications where this parameter is not a primary selection criterion for the specified voltage and current ratings.

Parameter Comparison

Engineering Selection Recommendations

Both P3100ECMCL and P3100ECL maintain active product status within the Littelfuse SIDACtor® series and satisfy identical regulatory requirements under RoHS3 and REACH standards. Selection between these parts should be based on inventory availability and application-specific requirements. The P3100ECMCL carries 867 units in stock, while the P3100ECL provides 8290 units. Both components are rated for unlimited moisture sensitivity and carry identical electrical performance across all critical parameters: 275V off-state voltage, 350V breakover voltage, 400A peak pulse current (8/20µs), and 150mA hold current. The capacitance difference (45pF versus 70pF) does not affect substitution eligibility for standard TVS thyristor applications.

Frequently Asked Questions (FAQ)

Q: Can P3100ECL replace P3100ECMCL in my circuit?

A: Yes. Both parts are electrically equivalent across all critical parameters: off-state voltage, breakover voltage, on-state voltage, peak pulse current ratings, and hold current. Both use identical TO-226-2 through-hole packaging and maintain the same compliance certifications.

Q: What is the difference between these two parts?

A: The primary difference is capacitance: P3100ECMCL is rated at 45pF while P3100ECL is rated at 70pF. Both parts share identical voltage and current specifications, package type, and regulatory compliance status.

Q: Are there any package compatibility concerns?

A: No. Both parts use TO-226-2, TO-92-2 (TO-226AC) packaging with through-hole mounting. PCB layouts and footprints are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both P3100ECMCL and P3100ECL are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1).

Q: Which part should I select based on availability?

A: Selection should prioritize application requirements and inventory status. P3100ECL offers significantly higher stock availability (8290 units versus 867 units). If capacitance specification is not a critical design parameter, P3100ECL is the preferred choice for supply chain continuity.
