ES1CL MQG Equivalent & Substitute Parts

Part Overview

The ES1CL MQG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 150 V DC reverse voltage and 1 A average rectified current. This component is classified as a fast recovery diode with a reverse recovery time of 35 ns, suitable for surface mount applications in the DO-219AB (Sub SMA) package. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across all critical parameters. Alternative packaging formats or inventory configurations may necessitate substitution while preserving circuit functionality.

Substitute Part Grouping Explanation

Substitution of the ES1CL MQG is determined by strict equivalence across the following critical parameters:

Reverse Voltage Rating: 150 V DC maximum
Forward Current Rating: 1 A average rectified current
Forward Voltage Drop: 950 mV maximum at 1 A
Reverse Recovery Time: 35 ns
Reverse Leakage Current: 5 µA at 150 V
Package Type: DO-219AB (Sub SMA) surface mount
Operating Temperature Range: -55°C to 150°C junction temperature
Compliance: RoHS3 compliant, REACH unaffected

The ES1CL RVG maintains identical electrical specifications and mechanical compatibility with the ES1CL MQG. The primary distinction is packaging format: ES1CL RVG is supplied in Cut Tape (CT) configuration, whereas ES1CL MQG uses standard packaging. Both parts share the same base product number (ES1C) and are manufactured by Taiwan Semiconductor Corporation.

Engineering Selection Recommendations

Both ES1CL MQG and ES1CL RVG are active production parts manufactured by Taiwan Semiconductor Corporation with identical electrical and thermal specifications. Selection between these parts is based on supply chain requirements and packaging format preferences rather than functional performance differences.

ES1CL MQG is appropriate for applications where standard packaging configuration is specified or preferred.

ES1CL RVG is appropriate for high-volume manufacturing environments utilizing automated tape-and-reel assembly processes, as it is supplied in Cut Tape (CT) format with significantly higher inventory availability (59,700 pcs vs. 1,121 pcs).

Both parts maintain full compliance with RoHS3 and REACH regulations, carry unlimited moisture sensitivity rating (MSL 1), and are classified under identical export control parameters (EAR99, HTSUS 8541.10.0080). No functional or reliability differences exist between these alternatives.

Frequently Asked Questions (FAQ)

Q: Are ES1CL MQG and ES1CL RVG electrically identical?

A: Yes. Both parts share identical electrical specifications including 150 V reverse voltage rating, 1 A forward current rating, 950 mV forward voltage drop at 1 A, 35 ns reverse recovery time, and 5 µA reverse leakage current at 150 V.

Q: What is the difference between ES1CL MQG and ES1CL RVG?

A: The primary difference is packaging format. ES1CL RVG is supplied in Cut Tape (CT) configuration for automated assembly, while ES1CL MQG uses standard packaging. Both use the DO-219AB (Sub SMA) package type and are surface mount components.

Q: Can ES1CL RVG replace ES1CL MQG in existing designs?

A: Yes. The ES1CL RVG is a direct functional equivalent with identical mechanical compatibility. The DO-219AB package footprint and pin configuration are identical between both parts.

Q: Are there any compliance or regulatory differences?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, EAR99 export classification, and HTSUS code 8541.10.0080. Moisture sensitivity level (MSL 1) is unlimited for both parts.

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing process requirements. For automated tape-and-reel assembly, ES1CL RVG (Cut Tape format) is standard. For manual assembly or specific packaging requirements, ES1CL MQG may be specified. Both are active production parts with equivalent long-term availability.

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

A: Both ES1CL MQG and ES1CL RVG operate across a junction temperature range of -55°C to 150°C, suitable for industrial and commercial applications.
