Substitute Part Grouping Explanation

Substitution of the ES1CLHMHG is based on strict equivalence across all critical electrical parameters and mechanical specifications. The substitute part ES1CL RVG maintains identical performance characteristics:

Key Parameters Determining Substitutability:

Voltage - DC Reverse (Vr) (Max): 150 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
Reverse Recovery Time (trr): 35 ns
Current - Reverse Leakage @ Vr: 5 µA @ 150 V
Capacitance @ Vr, F: 10 pF @ 4V, 1MHz
Package / Case: DO-219AB (Sub SMA)
Operating Temperature - Junction: -55°C to 150°C
Technology: Standard
Mounting Type: Surface Mount

Both parts share the same base product number (ES1C), manufacturer (Taiwan Semiconductor Corporation), and compliance certifications (ROHS3, REACH Unaffected, AEC-Q101). The primary difference is packaging format: ES1CLHMHG is supplied in standard packaging, while ES1CL RVG is supplied in Cut Tape (CT) format.

Engineering Selection Recommendations

Both ES1CLHMHG and ES1CL RVG are Active product status components manufactured by Taiwan Semiconductor Corporation with identical electrical specifications and mechanical compatibility. Selection between these parts is determined by packaging and supply requirements:

ES1CLHMHG is appropriate for applications where standard packaging format is specified or preferred, with current inventory of 1163 pieces available.

ES1CL RVG is appropriate for high-volume production environments requiring Cut Tape (CT) packaging format, with significantly higher inventory availability of 59700 pieces. This part is suitable for automated pick-and-place assembly processes.

Both parts carry AEC-Q101 automotive qualification, ROHS3 compliance, and REACH Unaffected status, making them suitable for automotive and industrial applications. The identical electrical parameters (150 V reverse voltage, 1 A average rectified current, 35 ns reverse recovery time) ensure direct functional equivalence in circuit applications. No derating or circuit modification is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can ES1CL RVG be used as a direct replacement for ES1CLHMHG in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus standard packaging). Direct substitution is valid provided the assembly process can accommodate the packaging format.

Q: What is the difference between the packaging formats?

A: ES1CLHMHG uses standard packaging, while ES1CL RVG is supplied in Cut Tape (CT) format. Cut Tape format is designed for automated assembly equipment and high-volume manufacturing. Standard packaging is suitable for manual assembly or lower-volume applications.

Q: Are both parts qualified for automotive applications?

A: Yes. Both ES1CLHMHG and ES1CL RVG carry AEC-Q101 automotive qualification and are suitable for automotive circuit applications.

Q: Do these parts have identical thermal characteristics?

A: Yes. Both parts have identical operating temperature range (-55°C to 150°C junction temperature) and identical reverse recovery time (35 ns).

Q: What is the significance of the 35 ns reverse recovery time?

A: The 35 ns reverse recovery time classifies both parts as fast recovery diodes, suitable for switching power supply applications and high-frequency rectification circuits where switching speed is critical.

Q: Are both parts RoHS compliant?

A: Yes. Both ES1CLHMHG and ES1CL RVG are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic components.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes, provided the assembly process and board layout accommodate the packaging format. The electrical performance and mechanical footprint (DO-219AB Sub SMA) are identical.

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

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