L513 SCR Module - Equivalent & Substitute Parts

Part Overview

The L513 is a thyristor module manufactured by Sensata-Crydom, classified as an SCR/Diode bridge module rated for 25A at 280VAC. The module features an 800V off-state voltage rating and is designed for single-phase bridge configurations with integrated SCRs and diodes in a through-hole package.

The L513 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L513 is based on strict electrical and mechanical parameter matching within the Sensata-Crydom L series thyristor module portfolio. The following parameters define substitution eligibility:

• Electrical Equivalence: Identical off-state voltage (800V), gate trigger voltage (3V max), gate trigger current (100mA max), and surge current rating (300A @ 60Hz)
• Structural Equivalence: Bridge configuration with single-phase layout, containing 2 SCRs and 2 diodes
• Thermal Equivalence: Operating temperature range of -40°C to 125°C (TJ)
• Mechanical Equivalence: Through-hole mounting type, module package format
• Environmental Compliance: Moisture sensitivity level 1 (unlimited)

The L513F meets all these criteria and is identified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The L513F is a direct electrical and mechanical equivalent to the L513. All critical parameters—voltage ratings, current specifications, thermal range, and package format—are identical. The primary distinction is product status: the L513 is obsolete while the L513F maintains active production status.

For new designs or ongoing production requiring this thyristor module specification, the L513F is the appropriate selection. The active product status ensures continued availability, supply chain support, and compliance with current manufacturing standards. Both parts carry identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

The L513F is RoHS3 compliant and REACH affected, reflecting current regulatory requirements for active products in this category.

Frequently Asked Questions (FAQ)

Q: Can the L513F be used as a direct replacement for the L513?

A: Yes. The L513F is electrically and mechanically identical to the L513 across all specified parameters, including voltage ratings, current specifications, temperature range, and through-hole mounting configuration.

Q: What is the primary reason to substitute the L513 with the L513F?

A: The L513 is obsolete. The L513F is an active product from the same manufacturer and series, ensuring supply availability and ongoing support.

Q: Are there differences in packaging between the L513 and L513F?

A: Both parts use identical module packaging with through-hole mounting. The L513F is supplied in bulk packaging, while the L513 was supplied in standard packaging. This does not affect electrical or mechanical compatibility.

Q: Do compliance certifications differ between the two parts?

A: Both parts share identical ECCN and HTSUS classifications. The L513F carries RoHS3 compliance and REACH affected status, reflecting current regulatory standards for active products.

Q: Are there any thermal or electrical performance differences?

A: No. Both parts operate across the identical temperature range (-40°C to 125°C TJ) and maintain identical electrical specifications for gate trigger voltage, gate trigger current, and surge current ratings.
