BTA201-600E,112 Equivalent & Substitute Parts

Part Overview

The BTA201-600E,112 is a logic-sensitive gate TRIAC manufactured by WeEn Semiconductors, rated for 600 V off-state voltage and 1 A on-state current in a TO-92-3 through-hole package. The device is active and RoHS compliant. Substitute parts are identified based on matching electrical specifications and mechanical compatibility to ensure functional equivalence in circuit applications.

Substitute Part Grouping Explanation

Substitute parts are grouped based on the following critical parameters that determine functional equivalence:

Voltage - Off State: Must be 600 V
Current - On State (It (RMS)) (Max): Must be 1 A or higher
Triac Type: Must be Logic - Sensitive Gate
Package / Case: Must be TO-92-3 or TO-226-3 compatible
Mounting Type: Must be Through Hole

Parts meeting these criteria are electrically and mechanically compatible with the BTA201-600E,112. Variations in gate trigger voltage (Vgt), gate trigger current (Igt), and hold current (Ih) within the specified ranges do not prevent substitution, as these parameters remain within acceptable operating margins for sensitive-gate TRIAC applications.

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct replacement of the BTA201-600E,112. Selection among substitutes should be based on:

Littelfuse Q601E3 and Q601E3RP: Both parts offer extended lower operating temperature range (-65°C) and higher hold current (15 mA), providing enhanced performance margin in sensitive-gate applications. Both are ROHS3 compliant.

STMicroelectronics Z0103MA series (1AA2, 2AL2, 5AL2): These parts feature lower gate trigger current (3 mA) and are available in bulk and cut tape packaging. Operating temperature range matches the original part (-40°C ~ 125°C). All variants are ROHS3 compliant.

STMicroelectronics Z0107MA 1AA2: Offers gate trigger current of 5 mA with hold current of 10 mA, providing balanced performance characteristics. ROHS3 compliant with standard operating temperature range.

STMicroelectronics Z0109MA series (1AA2, 2AL2, 5AL2): Gate trigger current matches the original specification (10 mA) with hold current of 10 mA. Available in bulk and cut tape packaging. All variants are ROHS3 compliant.

STMicroelectronics Z00607MA 5BL2: This part is rated for 800 mA on-state current, which is lower than the 1 A specification. Use only in applications where the reduced current rating is acceptable.

Frequently Asked Questions (FAQ)

Q: Can Z00607MA 5BL2 be used as a direct replacement for BTA201-600E,112?

A: Z00607MA 5BL2 has a maximum on-state current of 800 mA, compared to 1 A for the BTA201-600E,112. It is suitable only for applications where the circuit current does not exceed 800 mA.

Q: What is the difference between Q601E3 and Q601E3RP?

A: Both parts are electrically identical. Q601E3RP is supplied in cut tape packaging, while Q601E3 is supplied in bulk packaging. Selection depends on assembly process requirements.

Q: Are all STMicroelectronics Z0103MA variants interchangeable?

A: Yes. Z0103MA 1AA2, Z0103MA 2AL2, and Z0103MA 5AL2 are electrically identical. The suffix indicates packaging format: 1AA2 is bulk, 2AL2 and 5AL2 are cut tape variants.

Q: Do substitute parts require circuit redesign?

A: No. All listed substitutes maintain the same voltage rating (600 V), on-state current (1 A or higher), and package form factor (TO-92-3). Gate trigger parameters remain within acceptable operating ranges for sensitive-gate TRIAC circuits.

Q: Which substitute offers the widest operating temperature range?

A: Littelfuse Q601E3 and Q601E3RP both operate from -65°C to 125°C, providing the widest temperature range among available substitutes.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original BTA201-600E,112 is RoHS compliant. All listed substitutes are either RoHS compliant or ROHS3 compliant, meeting current environmental standards.
