BTA201-800B,112 Equivalent & Substitute Parts

Part Overview

The BTA201-800B,112 is a standard TRIAC rated for 800V off-state voltage and 1A on-state current in a through-hole TO-92-3 package. Manufactured by WeEn Semiconductors, this component is active and RoHS compliant. Substitute parts may be required due to inventory constraints, end-of-life considerations, or application-specific performance requirements such as gate sensitivity or current capacity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Voltage - Off State: Must equal 800V
• Mounting Type: Through Hole or Surface Mount (application-dependent)
• Operating Temperature Range: Must support -40°C ~ 125°C minimum
• RoHS Compliance: Must meet regulatory requirements

The BTA201-800B,112 has two identified substitutes:

1. L0109NE (Littelfuse Inc.): Logic-Sensitive Gate TRIAC, 800V, 1A, through-hole TO-92. Lower gate trigger current (10mA vs 50mA) and hold current (10mA vs 30mA) enable operation with reduced gate drive requirements.

2. MAC4DCN-1G (Littelfuse Inc.): Standard TRIAC, 800V, 4A, surface-mount TO-252 (DPAK). Higher current rating (4A vs 1A) and different mounting technology for applications requiring increased current capacity or surface-mount assembly.

Parameter Comparison

Engineering Selection Recommendations

L0109NE Selection Criteria:

• Direct through-hole replacement for BTA201-800B,112
• Identical 800V voltage rating and 1A current rating
• Lower gate trigger and hold current specifications reduce gate drive circuit complexity
• ROHS3 compliance exceeds RoHS requirements
• Suitable for applications where gate drive power budget is constrained

MAC4DCN-1G Selection Criteria:

• Surface-mount alternative for redesigned PCB layouts
• 4A current rating supports higher load currents than the original 1A specification
• Identical 800V voltage rating maintains voltage compatibility
• ROHS3 compliance and REACH unaffected status meet regulatory requirements
• Requires PCB footprint modification from through-hole to TO-252 (DPAK)

Frequently Asked Questions (FAQ)

Q: Can L0109NE directly replace BTA201-800B,112 without circuit modification? A: L0109NE is a direct through-hole replacement with identical voltage and current ratings. The lower gate trigger current (10mA vs 50mA) may reduce gate drive requirements but does not prevent substitution in existing circuits.

Q: What is the primary difference between L0109NE and BTA201-800B,112? A: L0109NE is classified as a Logic-Sensitive Gate TRIAC with reduced gate trigger and hold current specifications, while BTA201-800B,112 is a Standard TRIAC. Both operate at 800V and 1A.

Q: When should MAC4DCN-1G be selected over L0109NE? A: MAC4DCN-1G is selected when application requirements include higher current capacity (4A vs 1A) or when surface-mount assembly is preferred. PCB redesign is required due to different package type (TO-252 DPAK vs TO-92-3).

Q: Are all substitute parts RoHS compliant? A: Yes. BTA201-800B,112 is RoHS Compliant. L0109NE and MAC4DCN-1G are both ROHS3 Compliant, meeting or exceeding regulatory requirements.

Q: What is the impact of different gate trigger voltage specifications? A: L0109NE and MAC4DCN-1G both have lower maximum gate trigger voltage (1.3V vs 1.5V). This indicates improved gate sensitivity and may reduce gate drive circuit power consumption.

Q: Can MAC4DCN-1G be used in a through-hole PCB design? A: No. MAC4DCN-1G uses a surface-mount TO-252 (DPAK) package. Through-hole PCB designs require L0109NE or equivalent through-hole packages.
