RS1BLHM2G Equivalent & Substitute Parts

Part Overview

The RS1BLHM2G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 800 mA average rectified current. This Surface Mount Sub SMA device is designed for fast recovery applications with a reverse recovery time of 150 ns and forward voltage of 1.3 V at 800 mA. The part carries AEC-Q101 automotive qualification and is ROHS3 compliant.

The RS1BLHM2G is currently in Active product status. Substitute parts become necessary when the primary part experiences inventory constraints, supply chain disruptions, or when design requirements permit selection from equivalent alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS1BLHM2G is determined by strict equivalence across the following critical 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
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

The RS1BL is identified as a parametric equivalent to the RS1BLHM2G. Both parts share identical electrical ratings and mechanical specifications. The primary distinction is packaging format: RS1BLHM2G is supplied in standard packaging, while RS1BL is supplied in Tape & Reel (TR) format. Additionally, RS1BL carries a product status designation of "Not For New Designs," indicating it is suitable for replacement and maintenance applications but not recommended for new product development.

Parameter Comparison

Engineering Selection Recommendations

For New Product Development: The RS1BLHM2G is the appropriate selection. This part maintains Active product status and is suitable for incorporation into new designs. It carries full AEC-Q101 automotive qualification and ROHS3 compliance, meeting current regulatory and quality standards.

For Replacement and Maintenance Applications: The RS1BL serves as a direct electrical and mechanical equivalent. Although designated "Not For New Designs," this part is electrically and mechanically identical to the RS1BLHM2G and is suitable for field replacement, repair, and maintenance of existing systems. The Tape & Reel packaging format of RS1BL is appropriate for high-volume production replacement scenarios.

Compliance Considerations: Both parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements. Both carry AEC-Q101 automotive qualification, confirming suitability for automotive-grade applications.

Frequently Asked Questions (FAQ)

Q: Can RS1BL be used as a direct replacement for RS1BLHM2G in new designs?

A: RS1BL is electrically and mechanically equivalent to RS1BLHM2G. However, RS1BL carries a "Not For New Designs" product status designation. For new product development, RS1BLHM2G is the recommended selection. RS1BL is appropriate for replacement and maintenance applications.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching the following parameters: Voltage - DC Reverse (Vr) (Max) of 100 V, Current - Average Rectified (Io) of 800 mA, Voltage - Forward (Vf) (Max) of 1.3 V @ 800 mA, Reverse Recovery Time (trr) of 150 ns, and Current - Reverse Leakage @ Vr of 5 µA @ 100 V. Both RS1BLHM2G and RS1BL meet these specifications identically.

Q: Are there packaging differences between RS1BLHM2G and RS1BL?

A: Yes. RS1BLHM2G is supplied in standard packaging format, while RS1BL is supplied in Tape & Reel (TR) format. Both use the DO-219AB package case and Sub SMA supplier device package. The packaging format difference does not affect electrical or mechanical compatibility; it reflects supply chain and production volume considerations.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RS1BLHM2G and RS1BL carry AEC-Q101 automotive qualification and are graded as Automotive components. Both are ROHS3 compliant and REACH unaffected, meeting current automotive and environmental standards.

Q: What is the operating temperature range for these parts?

A: Both RS1BLHM2G and RS1BL operate across a junction temperature range of -55°C to 150°C, providing equivalent thermal performance across industrial and automotive applications.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, from an electrical and mechanical standpoint. Both parts use Surface Mount technology with DO-219AB package case and Sub SMA supplier device package. PCB layout and assembly processes designed for one part accommodate the other without modification. Packaging format (standard versus Tape & Reel) affects supply chain logistics but not PCB-level compatibility.
