STN1NK60Z Equivalent & Substitute Parts

Part Overview

The STN1NK60Z is an N-Channel 600V 300mA MOSFET manufactured by STMicroelectronics in the SuperMESH™ series. This surface mount device is housed in a SOT-223 package and is designed for applications requiring high voltage switching with moderate current handling. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified based on matching electrical characteristics within the N-Channel MOSFET category, including drain-source voltage rating, continuous drain current capability, gate charge specifications, and thermal performance parameters. Alternative components are necessary when primary inventory is unavailable or when design flexibility permits operation within specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the STN1NK60Z is based on the following criteria:

Parametric Equivalent Classification: Parts matching all critical electrical parameters including Vdss (600V), Id (300mA), Rds On (15 Ohm @ specified conditions), gate charge (6.9 nC), and power dissipation (3.3W) within the same package type (SOT-223) are classified as parametric equivalents. These parts are direct functional replacements with identical performance characteristics.

Similar Part Classification: Parts with reduced voltage rating (Vdss < 600V) or different current specifications are classified as similar parts. These components operate within the same package and mounting technology but with different electrical performance envelopes. Similar parts require circuit-level evaluation to confirm suitability for the intended application.

Key Substitution Parameters:

• Drain to Source Voltage (Vdss)
• Continuous Drain Current (Id)
• On-State Resistance (Rds On)
• Gate Charge (Qg)
• Power Dissipation capability
• Package and mounting compatibility

Engineering Selection Recommendations

STN1NK60ZL (Parametric Equivalent): This STMicroelectronics part is a direct parametric equivalent to the STN1NK60Z with identical electrical specifications across all measured parameters. Both parts maintain Active product status and are suitable for new designs. Selection between STN1NK60Z and STN1NK60ZL is determined by inventory availability and packaging format (Cut Tape vs. Digi-Reel for STN1NK60Z; Cut Tape vs. Digi-Reel for STN1NK60ZL).

BSP126,115 and BSP126,135 (Similar Parts): These Nexperia components operate at reduced voltage (250V Vdss) compared to the STN1NK60Z (600V Vdss). Both parts are marked as Not For New Designs, indicating obsolescence trajectory. These components are suitable only for legacy system maintenance or applications where 250V voltage rating is sufficient. The lower power dissipation (1.5W vs. 3.3W) and reduced gate charge specifications indicate different thermal and switching characteristics.

Compliance and Certification: All listed parts maintain RoHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating. Selection should prioritize parts with Active product status for new design implementations.

Frequently Asked Questions (FAQ)

Q: Can BSP126,115 or BSP126,135 be used as direct replacements for STN1NK60Z?

A: No. These Nexperia parts have a maximum Vdss rating of 250V, compared to 600V for the STN1NK60Z. Direct substitution is only possible in applications where the circuit operates at voltages not exceeding 250V. Additionally, both Nexperia parts are marked Not For New Designs, indicating obsolescence status.

Q: What is the difference between STN1NK60Z and STN1NK60ZL?

A: Both parts are parametrically identical with matching Vdss (600V), Id (300mA), Rds On (15 Ohm), gate charge (6.9 nC), and power dissipation (3.3W). The primary difference is packaging format: STN1NK60Z is available in Cut Tape and Digi-Reel formats, while STN1NK60ZL follows the same packaging options. Both maintain Active product status and are suitable for new designs.

Q: Are all substitute parts available in SOT-223 packaging?

A: Yes. All listed substitute parts (STN1NK60ZL, BSP126,115, BSP126,135) are supplied in SOT-223 surface mount packages with TO-261-4 and TO-261AA case designations, ensuring mechanical and thermal compatibility with the STN1NK60Z.

Q: What compliance certifications apply to all listed parts?

A: All parts maintain RoHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating. ECCN classification is EAR99 for all components, and HTSUS code 8541.29.0095 applies uniformly across the part group.

Q: Which substitute part should be selected for new product designs?

A: STN1NK60ZL is the recommended parametric equivalent for new designs, offering identical electrical performance to the STN1NK60Z with Active product status. The Nexperia BSP126 variants are not recommended for new designs due to Not For New Designs status and reduced voltage rating.

Q: How do gate charge specifications affect substitution decisions?

A: Gate charge (Qg) directly impacts switching speed and driver circuit requirements. The STN1NK60Z and STN1NK60ZL both specify 6.9 nC @ 10V. The BSP126 variants do not provide gate charge specifications in the available data, requiring additional evaluation if switching frequency or driver compatibility is critical to the application.

Q: What is the significance of the SuperMESH™ series designation?

A: SuperMESH™ is a STMicroelectronics technology series for high-voltage MOSFETs. Both STN1NK60Z and STN1NK60ZL belong to this series. The Nexperia BSP126 parts do not carry this designation, indicating different internal device architecture and manufacturing process.
