CS220-16M Equivalent & Substitute Parts

Part Overview

The CS220-16M is a 600V 16A Standard Recovery SCR (Silicon Controlled Rectifier) in TO-220-3 through-hole packaging manufactured by Central Semiconductor Corp. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates across a temperature range of -40°C to 125°C and is suitable for applications requiring thyristor switching and control functions at moderate current levels.

Substitute Part Grouping Explanation

Substitution of the CS220-16M is determined by the following critical parameters:

Voltage Rating (Off State): Must be 600 V or higher to maintain blocking capability
Current Rating (On State RMS): Must support minimum 16 A RMS current requirement
Gate Trigger Parameters: Vgt (Max) 1.5 V and Igt (Max) 15 mA define gate drive compatibility
On State Voltage (Vtm): Maximum 1.6 V ensures thermal performance consistency
SCR Type: Standard Recovery classification ensures switching characteristics compatibility
Package: TO-220-3 through-hole mounting maintains mechanical and thermal interface compatibility
Operating Temperature Range: -40°C to 125°C defines environmental suitability

The TXN612RG from STMicroelectronics meets the voltage, gate trigger, on-state voltage, SCR type, package, and temperature requirements. However, its on-state current rating of 12 A RMS is below the 16 A requirement of the CS220-16M, making it suitable only for applications with reduced current demands.

Engineering Selection Recommendations

The TXN612RG is an active product from STMicroelectronics with ROHS3 compliance and REACH unaffected status, providing supply chain continuity for the obsolete CS220-16M. Both components share identical voltage ratings, gate trigger specifications, on-state voltage characteristics, SCR type classification, package configuration, and operating temperature range.

The primary design consideration is the current rating differential: the TXN612RG supports 12 A RMS versus the CS220-16M's 16 A RMS capability. Selection of the TXN612RG is appropriate for applications where the actual operating current does not exceed 12 A RMS. Applications requiring the full 16 A RMS capability of the original part require evaluation of alternative 600V SCR devices with higher current ratings in compatible packaging.

Frequently Asked Questions (FAQ)

Q: Can the TXN612RG directly replace the CS220-16M in all applications?

A: Direct replacement is limited by current rating. The TXN612RG is suitable only for applications where operating current remains at or below 12 A RMS. Applications requiring 16 A RMS operation require alternative components.

Q: Are the gate drive requirements identical between these parts?

A: Yes. Both components specify identical maximum gate trigger voltage (1.5 V) and gate trigger current (15 mA), ensuring gate drive circuit compatibility.

Q: Do both parts use the same package and mounting method?

A: Yes. Both components use TO-220-3 through-hole packaging, maintaining identical mechanical fit and thermal interface characteristics on PCB assemblies.

Q: What is the significance of the product status difference?

A: The CS220-16M is obsolete, indicating discontinued manufacturing and limited availability. The TXN612RG is active, ensuring ongoing supply and manufacturing support from STMicroelectronics.

Q: Are there compliance or regulatory differences?

A: The TXN612RG carries ROHS3 compliance certification, whereas the CS220-16M status is not specified in the provided data. Both are REACH unaffected and classified under identical ECCN and HTSUS codes.
