Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HS1AL MHG are identified through parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following matching criteria:

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

Mechanical Parameters (Must Match Exactly):

• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Compliance & Status (Must Match Exactly):

• Technology: Standard
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts may differ in packaging format (tape reel, cut tape, or bulk) without affecting electrical or mechanical compatibility, as these represent distribution methods only.

Parameter Comparison

Engineering Selection Recommendations

The HS1AL RVG is a direct parametric equivalent to the HS1AL MHG. Both components share identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. Selection between these parts is determined by packaging and inventory requirements rather than technical performance.

HS1AL MHG is suitable for applications where standard packaging format is required and current inventory availability is adequate.

HS1AL RVG is suitable for applications requiring cut tape (CT) packaging format, offering higher inventory availability (2549 pcs vs. 989 pcs) and alternative distribution logistics.

Both parts maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with current manufacturing and environmental standards. No performance degradation or functional limitation occurs when substituting between these parts in any circuit application.

Frequently Asked Questions (FAQ)

Q: Can HS1AL RVG be used as a direct replacement for HS1AL MHG?

A: Yes. Both parts are parametrically identical across all electrical specifications (50 V reverse voltage, 1 A rectified current, 950 mV forward voltage, 50 ns recovery time) and mechanical parameters (DO-219AB Sub SMA package, surface mount, -55°C to 150°C operating range). The only difference is packaging format (cut tape vs. standard), which does not affect circuit performance.

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

A: The parts differ only in packaging format. HS1AL MHG uses standard packaging, while HS1AL RVG is supplied in cut tape (CT) format. All electrical and mechanical specifications are identical. The packaging difference affects only handling, storage, and assembly logistics.

Q: Are both parts ROHS3 compliant?

A: Yes. Both HS1AL MHG and HS1AL RVG are ROHS3 compliant with REACH Unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

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 requiring wide thermal operating windows.

Q: Can these diodes be used in fast switching applications?

A: Yes. Both parts are classified as fast recovery diodes with a reverse recovery time of 50 ns, enabling use in switching power supplies, inverters, and other applications requiring rapid diode turn-off characteristics.

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

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

Q: Are there any inventory considerations when selecting between these parts?

A: HS1AL RVG has higher current inventory availability (2549 pcs) compared to HS1AL MHG (989 pcs). Selection based on packaging format and delivery timeline may be necessary for high-volume production requirements.
