Substitute Part Grouping Explanation

Substitute parts for the RS1GLHRUG are identified through parametric equivalence based on the following critical electrical and mechanical parameters:

Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 400 V
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ rated current
Reverse Recovery Time (trr): 150 ns
Current - Reverse Leakage @ Vr: 5 µA @ 400 V
Speed Classification: Fast Recovery ≤ 500ns, > 200mA
Operating Temperature - Junction: -55°C to 150°C
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant

Substitutes are grouped into two categories based on current rating and package configuration:

Category 1 - Identical Package (DO-219AB Sub SMA): Parts maintaining the same package form factor and current rating of 800mA.

Category 2 - Upgraded Current Rating (SOD-123F): Parts with higher current capacity (1A) in an alternative surface mount package, suitable for applications where package footprint flexibility exists.

Engineering Selection Recommendations

RS1GL R3G (Preferred Direct Substitute): The RS1GL R3G is the primary equivalent substitute for the RS1GLHRUG. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, thermal operating range, and package configuration (DO-219AB Sub SMA). The RS1GL R3G differs only in packaging format (Tape & Reel versus cut tape), making it suitable for high-volume production environments. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating. This substitute provides direct form-fit-function compatibility with no circuit redesign required.

RS1GL (Alternative Substitute with Upgraded Current Rating): The RS1GL manufactured by SMC Diode Solutions is a parametric equivalent with upgraded current capacity (1A versus 800mA). This part maintains all critical electrical parameters including 400V reverse voltage, 150ns reverse recovery time, and identical forward voltage characteristics. The primary distinction is the alternative package format (SOD-123F versus DO-219AB Sub SMA). This substitute is applicable in applications where the higher current rating provides design margin and package footprint flexibility is acceptable. ROHS3 compliance is maintained; however, REACH status differs (REACH Affected versus REACH Unaffected).

Compliance Considerations: All substitute parts maintain active product status and ROHS3 compliance. The RS1GL R3G preserves identical REACH and ECCN classifications. Selection between substitutes depends on packaging requirements, supply chain availability, and regulatory compliance needs specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can RS1GL R3G be used as a direct replacement for RS1GLHRUG?

A: Yes. The RS1GL R3G is a direct parametric equivalent with identical electrical specifications, thermal range, and package configuration. The only difference is the packaging format (Tape & Reel versus cut tape), which does not affect circuit performance.

Q: What is the primary difference between RS1GL and RS1GLHRUG?

A: The RS1GL has a higher average rectified current rating (1A versus 800mA) and uses an alternative surface mount package (SOD-123F versus DO-219AB Sub SMA). All other electrical parameters, including reverse voltage, forward voltage, and recovery time, are identical. Circuit board layout modifications are required to accommodate the different package footprint.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitutes (RS1GL R3G and RS1GL) are ROHS3 compliant. The RS1GL R3G maintains identical REACH and ECCN classifications to the main part. The RS1GL has REACH Affected status, which may require evaluation based on end-use application requirements.

Q: Can the RS1GL be used in automotive applications?

A: The RS1GL R3G is qualified to AEC-Q101 automotive standards. The RS1GL does not list AEC-Q101 qualification in the provided specifications. Automotive application requirements should be verified against the specific qualification status of the selected substitute.

Q: What is the impact of package change when substituting with RS1GL?

A: The RS1GL uses SOD-123F package instead of DO-219AB Sub SMA. This requires circuit board layout redesign to accommodate the different footprint dimensions and pin configuration. Electrical performance remains equivalent; however, PCB assembly tooling and placement programs must be updated.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Inventory availability differs between parts. RS1GL R3G has 1036 pieces in stock, RS1GLHRUG has 1006 pieces, and RS1GL has 1061300 pieces available. Supply chain requirements and lead time considerations should factor into substitute selection.

Q: Do all substitutes have the same operating temperature range?

A: Yes. All parts (RS1GLHRUG, RS1GL R3G, and RS1GL) operate across the identical junction temperature range of -55°C to 150°C.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is based on matching critical electrical parameters: reverse voltage (400V), forward voltage (1.3V), reverse recovery time (150ns), reverse leakage current (5µA), speed classification (fast recovery), thermal range (-55°C to 150°C), surface mount mounting type, and RoHS3 compliance. Package configuration and current rating may differ if the application permits.
