L412F Equivalent & Substitute Parts Reference

Part Overview

The Sensata-Crydom L412F is a thyristor module designed for bridge rectification in single-phase systems, with a maximum off-state voltage of 600 V and a maximum RMS on-state current of 22 A. The device incorporates two SCRs and two diodes in a bridge layout. Its product status is classified as "Not For New Designs," indicating that alternative models must be considered for new or ongoing projects. Identifying substitute products with exactly matching electrical and mechanical parameters is essential for maintaining design integrity and compliance.

Substitute Part Grouping Explanation

Substitution between Sensata-Crydom L412F and approved equivalents, such as L413F, is determined solely by matching all key electrical, mechanical, and compliance parameters. The following fields form the definitive substitution criteria:

• Structure: Bridge, Single Phase - SCRs/Diodes (Layout 1)
• Number of SCRs, Diodes: 2 SCRs, 2 Diodes
• Voltage - Off State: 600 V
• Current - On State (It (AV)) (Max): 100 A
• Current - On State (It (RMS)) (Max): 22 A
• Voltage - Gate Trigger (Vgt) (Max): 2.5 V
• Current - Gate Trigger (Igt) (Max): 100 mA
• Current - Hold (Ih) (Max): 100 mA
• Operating Temperature: -40°C ~ 125°C (TJ)
• Package / Case: Module
• RoHS Compliance
• Moisture Sensitivity Level (MSL)
• ECCN
• HTSUS

Any alternative must match these parameters precisely, as per the provided data.

Parameter Comparison

Engineering Selection Recommendations

The Sensata-Crydom L412F is classified as "Not For New Designs." As a result, selection should favor parts with an "Active" product status and matching compliance requirements. Where RoHS and moisture sensitivity level (MSL) equivalence are verified, direct substitution is supported. Certifications such as EAR99 and HTSUS classifications must also match to maintain regulatory compliance. Only parts with identical key parameters and compliance certifications are considered suitable substitutes in this category.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for substituting the Sensata-Crydom L412F?
A1: Substitution requires identical values for all electrical, thermal, package, and compliance parameters provided, including off-state voltage, RMS current rating, SCR/diode count, gate trigger levels, package type, and environmental certifications.

Q2: Is the package form factor of L413F identical to L412F?
A2: Yes, both L412F and L413F use the "Module" package/case as specified.

Q3: Does the substitute part meet the same RoHS and MSL standards?
A3: Yes, L413F is ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), which matches the standards required for substitution with L412F.

Q4: Are there any thermal or operating range differences?
A4: No, both modules have an operating temperature range of -40°C to 125°C (TJ).

Q5: Do both modules hold the same regulatory classifications?
A5: Yes, both L412F and L413F are classified as ECCN: EAR99 and HTSUS: 8541.30.0080.
