Substitute Part Grouping Explanation

Substitute parts for the RS1D are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Voltage Rating: DC reverse voltage (Vr) must equal 200V maximum
Current Rating: Average rectified current (Io) must equal 1A
Forward Voltage: Forward voltage drop (Vf) must equal 1.3V maximum at 1A forward current
Recovery Characteristics: Reverse recovery time (trr) must equal 150ns; fast recovery classification (≤500ns, >200mA)
Leakage Current: Reverse leakage current must equal 5µA at 200V
Capacitance: Junction capacitance must equal 15pF at 4V, 1MHz
Temperature Range: Operating junction temperature range must span -65°C to 150°C
Package: Surface mount SMA (DO-214AC) package format
Compliance: RoHS3 compliance required

The RS1D-13-F manufactured by Diodes Incorporated meets all specified electrical and mechanical parameters and qualifies as a parametric equivalent substitute.

Engineering Selection Recommendations

The RS1D-13-F from Diodes Incorporated is a direct parametric equivalent to the RS1D from SMC Diode Solutions. Both components are Active product status and maintain identical electrical specifications across all critical parameters: reverse voltage rating, forward current capacity, forward voltage drop, recovery time characteristics, leakage current, and junction capacitance. Both components are RoHS3 compliant and operate across the same temperature range.

The primary distinction between these components is packaging format and regulatory status. The RS1D is supplied in Tape & Reel (TR) format, while the RS1D-13-F is available in Cut Tape (CT) and Digi-Reel® format. The RS1D carries REACH Affected status, whereas the RS1D-13-F is REACH Unaffected. Both components share the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Selection between these equivalent parts is determined by packaging requirements, supply chain availability, and regulatory compliance needs specific to the end application and destination market.

Frequently Asked Questions (FAQ)

Q: Can the RS1D-13-F be used as a direct replacement for the RS1D in existing circuit designs?

A: Yes. The RS1D-13-F meets all electrical and mechanical specifications of the RS1D. Both components have identical voltage ratings (200V), current ratings (1A), forward voltage characteristics (1.3V @ 1A), recovery time (150ns), leakage current (5µA @ 200V), and capacitance (15pF @ 4V, 1MHz). Both are surface mount SMA (DO-214AC) packages suitable for identical PCB layouts.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, typically used for high-volume automated assembly. Cut Tape (CT) and Digi-Reel® packaging supplies components on tape segments or alternative reel formats, often used for lower-volume applications or mixed-component orders. Both packaging formats contain identical components; the difference is in supply format and handling.

Q: Are there any temperature or thermal performance differences between these parts?

A: No. Both the RS1D and RS1D-13-F operate across the identical junction temperature range of -65°C to 150°C. Thermal performance characteristics are equivalent.

Q: What does REACH Affected versus REACH Unaffected status mean for component selection?

A: REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) is a European Union regulation. REACH Affected status indicates the component or its materials may contain substances subject to REACH requirements. REACH Unaffected status indicates no REACH-regulated substances are present. Selection depends on end-use market and regulatory requirements for the application.

Q: Do both parts have the same RoHS compliance status?

A: Yes. Both the RS1D and RS1D-13-F are RoHS3 compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these diodes be used interchangeably in high-frequency switching applications?

A: Yes. Both components have identical fast recovery characteristics (≤500ns, >200mA) and reverse recovery time of 150ns, making them suitable for identical high-frequency switching applications.
