STP7NK30Z Equivalent & Substitute Parts

Part Overview

The STP7NK30Z is an N-Channel MOSFET manufactured by STMicroelectronics, rated for 300V drain-to-source voltage and 5A continuous drain current in a TO-220 through-hole package. This device is part of the SuperMESH™ series and is classified as obsolete. Due to its obsolete status, equivalent substitute parts with active product status are necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STP7NK30Z is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Mounting Type: Through Hole
• Package / Case: TO-220-3
• Operating Temperature Range: -55°C to 150°C (TJ)

Electrical Performance Criteria:

• Drain to Source Voltage (Vdss): Equal to or greater than 300V
• Current - Continuous Drain (Id) @ 25°C: Equal to or greater than 5A (Tc)
• Power Dissipation (Max): Equal to or greater than 50W (Tc)

Regulatory & Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The STP10N60M2 qualifies as a substitute part because it meets all mandatory compatibility criteria and exceeds the electrical performance requirements while maintaining equivalent regulatory compliance.

Engineering Selection Recommendations

STP10N60M2 as Primary Substitute:

The STP10N60M2 is the appropriate substitute for the obsolete STP7NK30Z based on the following factors:

1. Product Status: The STP10N60M2 maintains active product status, ensuring continued availability and manufacturing support, whereas the STP7NK30Z is obsolete.

2. Regulatory Compliance: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) ratings, ensuring no regulatory barriers to substitution.

3. Electrical Performance: The STP10N60M2 exceeds the electrical specifications of the STP7NK30Z across all critical parameters:

   • Vdss: 600V (vs. 300V) provides enhanced voltage margin
   • Id: 7.5A (vs. 5A) provides increased current capacity
   • Power Dissipation: 85W (vs. 50W) provides thermal headroom

4. Package Compatibility: Both devices use identical TO-220-3 through-hole packaging, enabling direct mechanical substitution without PCB redesign.

5. Thermal Operating Range: Both parts operate across the identical temperature range (-55°C to 150°C TJ), maintaining thermal compatibility.

The STP10N60M2 is suitable for direct substitution in applications where the STP7NK30Z was previously specified, with the understanding that the substitute part provides superior electrical performance and active product support.

Frequently Asked Questions (FAQ)

Q: Can the STP10N60M2 be used as a direct replacement for the STP7NK30Z?

A: Yes. Both devices share identical FET type (N-Channel), technology (MOSFET), mounting type (Through Hole), and package configuration (TO-220-3). The STP10N60M2 meets or exceeds all electrical performance requirements of the STP7NK30Z.

Q: What are the key differences between these two parts?

A: The STP10N60M2 provides higher voltage rating (600V vs. 300V), higher continuous drain current (7.5A vs. 5A), higher power dissipation capability (85W vs. 50W), and active product status compared to the obsolete STP7NK30Z. The STP10N60M2 uses the MDmesh™ II Plus series technology versus the SuperMESH™ series of the STP7NK30Z.

Q: Are there any circuit design considerations when substituting the STP10N60M2 for the STP7NK30Z?

A: Circuit design remains compatible. The STP10N60M2 has slightly lower on-resistance (600 mOhm vs. 900 mOhm at comparable conditions), which reduces power dissipation. Gate charge is nearly identical (13.5 nC vs. 13 nC), ensuring compatible gate drive requirements. The maximum gate voltage specification differs slightly (±25V vs. ±30V), but this does not affect standard gate drive circuits.

Q: Do both parts have the same regulatory compliance?

A: Yes. Both the STP7NK30Z and STP10N60M2 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings. No regulatory barriers exist to substitution.

Q: What is the inventory status of these parts?

A: The STP7NK30Z has 1435 pieces in stock as new original inventory. The STP10N60M2 has 1296 pieces in stock as new original inventory. Both are available for immediate procurement.

Q: Is the TO-220-3 package identical for both parts?

A: Yes. Both devices use the TO-220-3 through-hole package configuration, enabling mechanical and thermal compatibility without PCB modification.

Q: Why is the STP7NK30Z classified as obsolete?

A: The STP7NK30Z is listed as obsolete by the manufacturer. The STP10N60M2, with superior electrical specifications and active product status, represents the current technology offering from STMicroelectronics for this device category.
