RSFJLHRUG Equivalent & Substitute Parts

Part Overview

The RSFJLHRUG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 500 mA average rectified current in a Surface Mount Sub SMA package (DO-219AB). This component is classified as Active product status with AEC-Q101 automotive qualification and ROHS3 compliance.

Substitute parts are necessary when the primary part number becomes unavailable due to inventory constraints, discontinuation, or supply chain disruptions. The parts listed in this reference maintain electrical and mechanical compatibility with the RSFJLHRUG within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSFJLHRUG is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 500 mA
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 500 mA
• Current - Reverse Leakage @ Vr: 5 µA @ 600 V
• Capacitance @ Vr, F: 4 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 150°C
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match):

• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Supplier Device Package: Sub SMA

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Reverse Recovery Time (trr) is permitted to vary within the Fast Recovery classification (≤ 500 ns) as this parameter does not affect functional compatibility in standard rectification applications. Packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Primary Selection: RSFJLHRUG

The RSFJLHRUG maintains Active product status and is recommended for new designs and production applications. This part number is currently in stock with 820 pieces available and carries AEC-Q101 automotive qualification, making it suitable for automotive and industrial rectification applications.

Secondary Selection: RSFJL R3G

The RSFJL R3G is electrically and mechanically equivalent to the RSFJLHRUG with identical reverse recovery time (250 ns). However, this part is marked as Discontinued at DiGi Electronics. Use this substitute only when RSFJLHRUG availability is constrained and existing inventory of RSFJL R3G is confirmed through direct supplier channels. Current inventory shows 1,068 pieces available.

Tertiary Selection: RSFJL

The RSFJL is a parametric equivalent with all electrical specifications matching the RSFJLHRUG except for reverse recovery time (500 ns versus 250 ns). This part is marked as Not For New Designs and should be used only as a last-resort substitute when both RSFJLHRUG and RSFJL R3G are unavailable. The extended reverse recovery time remains within the Fast Recovery classification (≤ 500 ns) and does not affect standard rectification functionality. Current inventory shows 12,300 pieces available in Tape & Reel packaging.

All three parts maintain identical compliance certifications (ROHS3, REACH Unaffected, MSL 1) and are suitable for the full operating temperature range (-55°C to 150°C).

Frequently Asked Questions (FAQ)

Q: Can RSFJL be used as a direct replacement for RSFJLHRUG?

A: RSFJL is electrically compatible with RSFJLHRUG for standard rectification applications. The reverse recovery time differs (500 ns versus 250 ns), but both values fall within the Fast Recovery classification (≤ 500 ns). All other electrical parameters, mechanical specifications, and compliance certifications are identical. However, RSFJL carries Not For New Designs status, so RSFJLHRUG is the preferred selection for new applications.

Q: What is the difference between RSFJL R3G and RSFJLHRUG?

A: RSFJL R3G and RSFJLHRUG are electrically and mechanically identical, including reverse recovery time (250 ns). The primary difference is product status: RSFJLHRUG is Active, while RSFJL R3G is Discontinued at DiGi Electronics. Both parts are suitable for equivalent circuit applications, but RSFJLHRUG is recommended for ongoing production due to its active status.

Q: Are packaging differences between these parts significant?

A: All three substitute parts use identical mechanical packaging: DO-219AB case with Sub SMA supplier device package and Surface Mount mounting type. Packaging format variations (Tape & Reel versus bulk) do not affect electrical or mechanical compatibility and relate only to supply and handling logistics.

Q: Do all substitute parts meet automotive qualification requirements?

A: The RSFJLHRUG carries AEC-Q101 automotive qualification. The substitute parts RSFJL and RSFJL R3G do not list AEC-Q101 qualification in the provided specifications. If automotive qualification is a design requirement, RSFJLHRUG is the only part in this group that meets this criterion.

Q: What compliance certifications apply to all substitute parts?

A: All three parts (RSFJLHRUG, RSFJL, and RSFJL R3G) are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). These certifications ensure compatibility with modern manufacturing processes and environmental regulations.

Q: Can reverse recovery time differences affect circuit performance?

A: Reverse recovery time (250 ns for RSFJLHRUG and RSFJL R3G versus 500 ns for RSFJL) affects switching transient behavior in high-frequency applications. For standard 50/60 Hz rectification and low-frequency switching applications, this difference is not functionally significant. High-frequency switching applications should use parts with shorter reverse recovery times (RSFJLHRUG or RSFJL R3G preferred over RSFJL).
