RS1JAL Equivalent & Substitute Parts

Part Overview

The RS1JAL is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 1 A average rectified current. This surface mount component is housed in a DO-221AC package with SMA flat leads and is classified as a fast recovery diode with a reverse recovery time of 250 ns. The part is Active in product status and fully compliant with RoHS3 and REACH regulations. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RS1JAL are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must match exactly:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Reverse Recovery Time (trr): 250 ns
• Current - Reverse Leakage @ Vr: 1 µA @ 600 V
• Capacitance @ Vr, F: 7 pF @ 4V, 1MHz
• Package / Case: DO-221AC, SMA Flat Leads
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Parts meeting all these criteria are classified as parametric equivalents and are suitable for direct substitution in applications where the RS1JAL is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the RS1JAL and FR1JAFC_R1_00001 are Active products with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences.

The RS1JAL, manufactured by Taiwan Semiconductor Corporation, is the primary part number with 6886 pieces in stock. The FR1JAFC_R1_00001, manufactured by Panjit International Inc., is a parametric equivalent with 3471 pieces in stock and serves as a substitute when the primary part is unavailable.

Both parts carry ROHS3 compliance and REACH Unaffected status, making them suitable for applications subject to environmental regulations. Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

The identical electrical performance, package configuration, and regulatory compliance of these parts ensure functional interchangeability in circuit applications. Selection should be based on procurement lead time, cost, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the FR1JAFC_R1_00001 be used as a direct replacement for the RS1JAL?

A: Yes. The FR1JAFC_R1_00001 is a parametric equivalent with identical voltage rating (600 V), current rating (1 A), forward voltage drop (1.3 V @ 1 A), reverse recovery time (250 ns), reverse leakage current (1 µA @ 600 V), junction capacitance (7 pF @ 4V, 1MHz), operating temperature range (-55°C to 150°C), and package configuration (DO-221AC, SMA Flat Leads). Direct substitution is supported.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the DO-221AC package with SMA flat leads and are configured for surface mount assembly. The physical footprint and PCB layout requirements are identical.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the RS1JAL and FR1JAFC_R1_00001 are ROHS3 compliant, REACH Unaffected, classified as EAR99 for export control, and carry HTSUS code 8541.10.0080. Both maintain Moisture Sensitivity Level 1 (Unlimited).

Q: What is the difference between the Thin SMA and SMAF-C supplier device packages?

A: The Thin SMA and SMAF-C designations refer to supplier-specific package nomenclature. Both parts conform to the same DO-221AC physical standard with SMA flat leads and are mechanically and electrically interchangeable.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on component availability, lead time, and cost. Both parts are Active products with identical performance characteristics.

Q: Are there any thermal or performance considerations when substituting between these parts?

A: No. Both parts share identical thermal specifications with an operating junction temperature range of -55°C to 150°C and identical electrical performance parameters. Thermal behavior and performance are equivalent.
