Equivalent & Substitute Parts for RS1BLHRQG

Part Overview

The RS1BLHRQG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100V DC reverse voltage and 800mA average rectified current. This surface mount component operates across a junction temperature range of -55°C to 150°C and features fast recovery characteristics with a reverse recovery time of 150 nanoseconds. The part is classified as Active product status and carries AEC-Q101 automotive qualification.

Substitute parts become necessary when the primary part number reaches end-of-life status, experiences supply constraints, or when alternative packaging configurations are required for manufacturing optimization. The RS1BLHRQG has identified equivalent alternatives that maintain identical electrical performance while offering different product statuses or packaging formats.

Substitute Part Grouping Explanation

Substitution eligibility for the RS1BLHRQG is determined by strict equivalence across the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 800 mA
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 800 mA
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 100 V
• Capacitance @ Vr, F: 10 pF @ 4V, 1MHz
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

The identified substitute part RS1BL maintains complete electrical equivalence across all parameters listed above. Differences between the main part and substitute are limited to product status classification and packaging format (Tape & Reel versus standard packaging), which do not affect functional performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

RS1BLHRQG Selection Criteria: The RS1BLHRQG is the preferred selection for new designs. This part carries Active product status, indicating ongoing manufacturer support and availability. It holds AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade reliability standards. The part maintains ROHS3 compliance and REACH unaffected status, meeting environmental regulatory requirements.

RS1BL Selection Criteria: The RS1BL substitute part is electrically and mechanically equivalent to the RS1BLHRQG across all functional parameters. However, this part is classified as Not For New Designs, indicating it is in mature or declining production phase. The RS1BL is available in Tape & Reel packaging format, which may be advantageous for high-volume manufacturing operations requiring automated component handling. Selection of RS1BL is appropriate for legacy system maintenance, repair operations, or applications where existing design validation has been completed on this specific part number.

Both parts share identical electrical performance, temperature operating range, package configuration, and regulatory compliance status. The choice between them depends on product lifecycle phase and manufacturing process requirements rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can RS1BL be used as a direct replacement for RS1BLHRQG in new product designs?

A: RS1BL maintains complete electrical and mechanical equivalence to RS1BLHRQG. However, RS1BL carries Not For New Designs status, indicating the manufacturer does not recommend this part for new development. For new designs, RS1BLHRQG is the appropriate selection due to its Active product status and ongoing manufacturer support.

Q: What is the difference between the packaging formats of these two parts?

A: RS1BLHRQG is supplied in standard packaging format, while RS1BL is supplied in Tape & Reel (TR) format. Both parts use the same DO-219AB package case and Sub SMA supplier device package. The packaging format difference affects component handling and automated assembly processes but does not alter electrical performance or physical dimensions.

Q: Are both parts qualified to the same automotive standards?

A: RS1BLHRQG carries AEC-Q101 automotive qualification. RS1BL specifications provided do not explicitly list AEC-Q101 qualification status. For applications requiring automotive-grade qualification, RS1BLHRQG is the specified selection.

Q: Do these parts have identical reverse recovery time characteristics?

A: Yes. Both RS1BLHRQG and RS1BL have a reverse recovery time (trr) of 150 nanoseconds and are classified as Fast Recovery diodes with speed ≤ 500ns for currents greater than 200mA. This parameter is identical across both parts.

Q: What is the moisture sensitivity level for these components?

A: Both parts have Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these parts be used interchangeably in existing production lines?

A: Electrical and mechanical parameters are identical, allowing functional interchangeability. However, the Tape & Reel packaging of RS1BL may require different handling equipment or feeder configurations compared to standard packaging of RS1BLHRQG. Manufacturing process compatibility should be evaluated based on existing assembly equipment specifications.
