HS1AL MQG Equivalent & Substitute Parts

Part Overview

The HS1AL MQG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or packaging format preferences while maintaining identical functional specifications.

Substitute Part Grouping Explanation

Substitute parts for the HS1AL MQG are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V
• Capacitance @ Vr, F: 20 pF @ 4V, 1MHz
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match Exactly):

• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Operating Temperature - Junction: -55°C to 150°C

Substitute parts may differ in packaging format (tape reel versus bulk) and inventory availability but maintain identical electrical performance and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the HS1AL MQG and HS1AL RVG are Active product status components manufactured by Taiwan Semiconductor Corporation with identical electrical specifications and mechanical compatibility. Selection between these parts is based on packaging format and inventory availability:

HS1AL MQG is suitable for applications requiring bulk packaging format with 863 pieces currently in stock.

HS1AL RVG is suitable for applications requiring cut tape (CT) packaging format with 2549 pieces currently in stock.

Both parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and identical functional performance across all electrical parameters. No performance degradation occurs when substituting between these parts within the same application circuit. Component selection should be based on assembly process requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can HS1AL RVG be used as a direct replacement for HS1AL MQG in circuit design?

A: Yes. Both parts are electrically and mechanically identical with matching voltage ratings (50 V), current ratings (1 A), forward voltage (950 mV @ 1 A), reverse recovery time (50 ns), and package specifications (DO-219AB Sub SMA). The only difference is packaging format (cut tape versus bulk).

Q: What is the difference between HS1AL MQG and HS1AL RVG?

A: The parts are identical in all electrical and mechanical specifications. The difference is in packaging format: HS1AL MQG is supplied in bulk packaging, while HS1AL RVG is supplied in cut tape (CT) format. Both are surface mount components in DO-219AB Sub SMA packages.

Q: Are both parts RoHS compliant?

A: Yes. Both HS1AL MQG and HS1AL RVG are ROHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity level).

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

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

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

A: HS1AL RVG in cut tape (CT) format is optimized for automated pick-and-place assembly. HS1AL MQG in bulk format requires manual handling or bulk feeder systems. Selection depends on assembly equipment capabilities.

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

A: Substitution compatibility is determined by: reverse voltage rating (50 V), average rectified current (1 A), forward voltage drop (950 mV @ 1 A), reverse recovery time (50 ns), reverse leakage current (5 µA @ 50 V), and junction capacitance (20 pF @ 4V, 1MHz). All these parameters must match exactly between the main part and substitute.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical RoHS status (ROHS3 Compliant), REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.10.0080).
