CMPS5062 TR Equivalent & Substitute Parts

Part Overview

The CMPS5062 TR is a Sensitive Gate SCR (Silicon Controlled Rectifier) rated for 200V off-state voltage with 250mA RMS on-state current capability in a surface mount SOT-23 package. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity. The part's sensitive gate characteristics and compact form factor define its application scope in low-power thyristor switching circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMPS5062 TR is determined by strict alignment with the following electrical and mechanical parameters:

• Off-state voltage rating: 200V minimum
• On-state current capability: 250mA RMS minimum
• Gate trigger voltage: 800mV maximum
• Gate trigger current: 200µA maximum
• On-state voltage drop: 1.7V maximum
• Hold current: 5mA maximum
• Package form factor: SOT-23 surface mount
• SCR type classification: Sensitive Gate

The CMPS5062 TR H qualifies as a direct substitute based on matching all critical electrical specifications and identical package configuration.

Engineering Selection Recommendations

The CMPS5062 TR H is the direct substitute for the obsolete CMPS5062 TR. Selection is based on the following factors:

• Both parts share identical package configuration (SOT-23-3) and mounting type (surface mount), ensuring mechanical compatibility without PCB redesign.
• The substitute maintains the 200V off-state voltage rating required for circuit operation.
• The CMPS5062 TR H carries Active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.
• The substitute is ROHS3 compliant, meeting current environmental and regulatory requirements.
• Both parts carry identical REACH and ECCN classifications, maintaining compliance posture.
• The substitute is rated for 160mA on-state current (RMS), which is lower than the main part's 250mA rating. Circuit designs operating at or below 160mA RMS can use this substitute without derating. Designs requiring the full 250mA capability must evaluate alternative sources or redesign considerations.

Frequently Asked Questions (FAQ)

Q: Can the CMPS5062 TR H replace the CMPS5062 TR in all applications?

A: The CMPS5062 TR H is mechanically and electrically compatible for applications operating at 160mA RMS or below. Applications requiring the full 250mA RMS capability of the original part require alternative solutions.

Q: What is the difference between CMPS5062 TR and CMPS5062 TR H?

A: Both parts are Sensitive Gate SCRs in SOT-23 packages with 200V ratings. The primary difference is product status: the TR variant is obsolete, while the TR H variant is active. The TR H is rated for 160mA RMS versus the TR's 250mA RMS on-state current.

Q: Are there package compatibility concerns with the substitute?

A: No. Both the main part and substitute use identical TO-236-3 / SC-59 / SOT-23-3 package specifications, ensuring direct PCB compatibility without layout modifications.

Q: Does the CMPS5062 TR H meet current compliance standards?

A: Yes. The CMPS5062 TR H is ROHS3 compliant and maintains REACH Unaffected status, meeting current environmental regulations.

Q: What should I do if my circuit requires 250mA RMS capability?

A: Circuits requiring the full 250mA RMS rating must source alternative thyristor components with matching electrical specifications or evaluate circuit redesign to operate within the 160mA RMS capability of the substitute part.
