Parameter Comparison

Engineering Selection Recommendations

Selection of STK5Q4U362J-E as a substitute for STK625-720MB-E is based on the following engineering criteria:

Regulatory and Compliance Alignment: Both parts share identical REACH, ECCN, and HTSUS classifications, ensuring regulatory compliance continuity. The STK5Q4U362J-E carries explicit ROHS3 compliance certification, providing additional environmental compliance assurance.

Product Status Consideration: Both components are classified as obsolete. When sourcing either part, availability through authorized distributors should be verified, as inventory levels for obsolete components are finite.

Functional Category: Both parts operate within the Power Management (PMIC) category and serve motor driver applications. The STK5Q4U362J-E provides half bridge driver functionality with specified electrical parameters (10A output current, 20A peak output, 12.5V–17.5V supply voltage, 400V maximum load voltage) suitable for AC motor control applications.

Packaging and Mounting: The STK5Q4U362J-E is specified as a 38-DIP Module with 24 leads in through-hole mounting configuration. PCB layout and socket compatibility must be evaluated against the original STK625-720MB-E design requirements.

Frequently Asked Questions (FAQ)

Q: Why is the STK625-720MB-E obsolete, and what does this mean for component sourcing?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory from authorized distributors may be available in limited quantities. The STK5Q4U362J-E is identified as a functional substitute within the same manufacturer's product line, though it is also obsolete. Long-term sourcing strategies should consider design migration to current-generation motor driver components.

Q: What are the key parameters that determine substitution compatibility between STK625-720MB-E and STK5Q4U362J-E?

A: Substitution is based on shared manufacturer (onsemi), identical regulatory classifications (REACH, ECCN, HTSUS), matching MSL ratings, and aligned motor driver functionality. The STK5Q4U362J-E provides half bridge driver capability with specified current handling (10A output, 20A peak) and voltage parameters (12.5V–17.5V supply, 400V load maximum).

Q: Are there packaging differences between these parts?

A: Yes. The STK5Q4U362J-E is specified as a 38-DIP Module with 24 leads in through-hole mounting, packaged in tubes. The STK625-720MB-E packaging details are not provided in available documentation. PCB footprint and socket compatibility must be verified before substitution.

Q: Does the STK5Q4U362J-E meet RoHS requirements?

A: The STK5Q4U362J-E is ROHS3 compliant. RoHS status for the STK625-720MB-E is not specified in available data. If RoHS compliance is a design requirement, the STK5Q4U362J-E provides documented compliance.

Q: What electrical parameters should be evaluated for motor driver substitution?

A: For the STK5Q4U362J-E, key electrical parameters include output current rating (10A per channel), peak output current (20A), supply voltage range (12.5V–17.5V), maximum load voltage (400V), and operating temperature (150°C junction temperature). These specifications must align with the original application's motor control requirements.

Q: What protection features are included in the STK5Q4U362J-E?

A: The STK5Q4U362J-E includes current limiting and under-voltage lockout (UVLO) fault protection, with status flag output for system monitoring.
