Substitute Part Grouping Explanation

Substitution of the IPD80R2K4P7ATMA1 is determined by strict alignment of the following critical parameters:

Voltage Rating: Both main and substitute parts must maintain 800V Vdss rating to ensure equivalent blocking capability in high-voltage applications.

Package Compatibility: Both devices use TO-252-3 DPAK surface mount packaging, ensuring mechanical and thermal interface compatibility with existing PCB layouts.

Current Rating: The substitute part (STD4LN80K5) provides 3A continuous drain current, which exceeds the 2.5A requirement of the main part, maintaining operational headroom.

On-State Resistance: Rds On values (2.4Ohm vs. 2.6Ohm) are within acceptable tolerance for equivalent conduction loss performance in switching applications.

Gate Charge: Lower gate charge in the substitute (3.7nC vs. 7.5nC) indicates improved switching speed characteristics, representing a performance enhancement rather than degradation.

Compliance: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating, ensuring equivalent environmental and regulatory compatibility.

Product Status: Both devices are Active in product status, confirming ongoing manufacturer support and availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (IPD80R2K4P7ATMA1): Use when the design requires the specific CoolMOS™ P7 series characteristics, existing inventory is available, or when the 2.5A current rating and 22W power dissipation are precisely matched to application requirements.

Substitute Selection (STD4LN80K5): Use when supply continuity is required, higher current capacity (3A) provides design margin, or when the MDmesh™ K5 series performance characteristics are acceptable. The lower gate charge (3.7nC) offers improved switching speed performance. Both devices maintain identical voltage rating (800V), package form factor (TO-252-3 DPAK), and compliance certifications (ROHS3, REACH unaffected, MSL 1).

Compliance Verification: Both parts are Active in product status, ensuring ongoing manufacturer support. Both carry ROHS3 compliance and REACH unaffected status, confirming equivalent environmental and regulatory standing for applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q: Can STD4LN80K5 directly replace IPD80R2K4P7ATMA1 in existing designs?

A: Yes. Both devices share identical 800V Vdss rating, TO-252-3 DPAK package, and surface mount compatibility. The substitute provides higher current capacity (3A vs. 2.5A) and lower gate charge (3.7nC vs. 7.5nC), representing equivalent or enhanced performance for the specified voltage class and package form factor.

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

A: The primary differences are manufacturer series (CoolMOS™ P7 vs. MDmesh™ K5), continuous drain current rating (2.5A vs. 3A), power dissipation capability (22W vs. 60W), and gate charge (7.5nC vs. 3.7nC). Voltage rating, package type, operating temperature range, and compliance certifications are identical.

Q: Are there any thermal considerations when substituting?

A: The STD4LN80K5 has higher power dissipation capability (60W vs. 22W), which may allow operation at higher power levels. However, thermal design should be based on actual application current and switching frequency requirements. Both devices operate across the same temperature range (-55°C to 150°C).

Q: Do both parts have the same gate drive requirements?

A: Both parts are specified for 10V drive voltage for maximum Rds On performance. The STD4LN80K5 accepts higher maximum gate voltage (±30V vs. ±20V), providing additional gate drive flexibility. Gate threshold voltages differ slightly (3.5V vs. 5V), which may affect switching characteristics in low-voltage gate drive circuits.

Q: Are packaging and moisture sensitivity equivalent?

A: Yes. Both devices use TO-252-3 DPAK surface mount packaging and carry MSL 1 (unlimited) moisture sensitivity rating, indicating equivalent handling and storage requirements.

Q: What compliance certifications apply to both parts?

A: Both IPD80R2K4P7ATMA1 and STD4LN80K5 are ROHS3 compliant and REACH unaffected, ensuring equivalent environmental and regulatory compliance for applications requiring these certifications.
