Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based solely on matching the following parameters: structure (Bridge, Single Phase - SCRs/Diodes (Layout 1)), number of SCRs/diodes (2 SCRs, 2 Diodes), off-state voltage (800 V), gate trigger voltage and current (Vgt and Igt), surge current capability (Itsm), operating temperature, mounting type, package/case, RoHS compliance, and MSL. Only parts that fulfill these criteria and are in the same product category (Thyristors) are considered valid equivalents.

Parameter Comparison

Engineering Selection Recommendations

The L313F is classified as obsolete, while the substitute L513F is active. Both parts satisfy RoHS requirements and share identical MSL ratings and ECCN classifications. The provided compliance information indicates the substitute part is suitable for selection in contexts where regulatory and certification equivalence is required. Packaging and mounting types differ, so compatibility with system mechanical requirements must be referenced from the parameters above.

Frequently Asked Questions (FAQ)

Q: What are the essential electrical parameters for substitution between L313F and L513F?
A: Key parameters include voltage-off state (800 V), number and layout of SCRs and diodes (2 SCRs, 2 Diodes; Bridge, Single Phase), gate trigger voltage and current, and surge current rating.

Q: Do both parts comply with RoHS and MSL requirements?
A: L313F is RoHS compliant and MSL 1 (Unlimited). L513F is ROHS3 compliant and MSL 1 (Unlimited).

Q: Is the mounting style interchangeable?
A: L313F is chassis mount; L513F is through hole. Mechanical system requirements determine interchangeability based on this parameter only.

Q: Why select L513F as a substitute for L313F?
A: L513F shares the same electrical specifications within the stated criteria and is active, matching compliance and certification parameters provided.

Q: Are both modules bridge, single-phase SCR/diode layouts?
A: Yes, both L313F and L513F are specified as bridge, single-phase SCR/diode modules with Layout 1.

Q: What differences exist in surge current rating?
A: L313F offers 2250A @ 60Hz; L513F specifies 300A @ 60Hz. Selection depends strictly on this parameter and application requirements.
