Substitute Part Grouping Explanation

Substitute parts for the SM4006PLHE3-TP are selected based on the following criteria:

Mandatory Compatibility Parameters:

• Package / Case: SOD-123F (surface mount)
• Mounting Type: Surface Mount
• Current - Average Rectified (Io): 1 A (minimum requirement)
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A (maximum allowable)
• Reverse Recovery Time (trr): 3 µs (standard recovery classification)
• Operating Temperature - Junction: -55°C to 150°C (minimum range)

Allowable Parameter Variations:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 800 V
• Current - Reverse Leakage @ Vr: Equal to or less than 1 µA
• Capacitance @ Vr, F: Equal to or less than 10 pF @ 4V, 1MHz

Substitute parts must satisfy all mandatory parameters and fall within allowable variations. Parts with higher reverse voltage ratings are acceptable as they provide enhanced performance margin without affecting circuit operation.

Engineering Selection Recommendations

The SM4007PLHE3-TP is a direct substitute for the SM4006PLHE3-TP based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters are identical or superior. The SM4007PLHE3-TP maintains the same forward voltage drop (1.1 V @ 1 A), reverse recovery time (3 µs), and junction temperature range (-55°C to 150°C). The increased reverse voltage rating (1000 V versus 800 V) provides additional design margin without introducing incompatibility.

Mechanical Compatibility: Both parts utilize identical SOD-123F surface mount packaging and mounting type, ensuring direct PCB footprint compatibility without layout modifications.

Regulatory and Compliance Status: Both parts carry identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining compliance requirements across supply chain transitions.

Product Availability: The SM4007PLHE3-TP carries active product status with substantial inventory availability (125,062 pieces), whereas the SM4006PLHE3-TP is obsolete. This substitution ensures long-term component procurement viability.

Frequently Asked Questions (FAQ)

Q: Can the SM4007PLHE3-TP be used as a direct replacement for the SM4006PLHE3-TP in existing designs?

A: Yes. The SM4007PLHE3-TP meets all electrical and mechanical compatibility requirements. The higher reverse voltage rating (1000 V versus 800 V) does not create incompatibility; it provides enhanced performance margin. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The SM4007PLHE3-TP has a maximum reverse voltage rating of 1000 V compared to 800 V for the SM4006PLHE3-TP. All other electrical parameters, including forward voltage, current rating, recovery time, and temperature range, are identical.

Q: Are the package dimensions identical between SM4006PLHE3-TP and SM4007PLHE3-TP?

A: Yes. Both parts use the SOD-123F surface mount package with identical footprint and mounting characteristics. PCB layout and assembly processes require no modification.

Q: Why is the SM4006PLHE3-TP listed as obsolete?

A: The SM4006PLHE3-TP has reached end-of-life status. The SM4007PLHE3-TP serves as the active product continuation within the Micro Commercial Co rectifier diode portfolio.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical REACH and ECCN classifications, maintaining consistent regulatory compliance across component substitution.

Q: What inventory considerations should be evaluated for this substitution?

A: The SM4006PLHE3-TP has limited remaining inventory (747 pieces). The SM4007PLHE3-TP has substantial active inventory (125,062 pieces), supporting long-term production requirements and supply chain continuity.
