Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly based on key electrical and mechanical parameters, which must match: Schottky technology, 40 V maximum DC reverse voltage, fast recovery speed, current rating within the applicable range, comparable forward voltage, reverse leakage current at maximum voltage, and compliance status. Mounting type and package/case are considered for mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Substitute selection is based solely on matching product status, RoHS compliance, and ECCN designation. BAT165E6327HTSA1 is active, RoHS3 compliant, shares the same ECCN and HTSUS classification as AK 04WS, and meets the required compliance levels.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when selecting a substitute for AK 04WS? A1: The critical parameters are technology (Schottky), maximum DC reverse voltage (40 V), average rectified current, forward voltage, recovery speed, reverse leakage current at rated voltage, compliance status, mounting type, and package compatibility.

Q2: Can BAT165E6327HTSA1 be directly substituted for AK 04WS? A2: BAT165E6327HTSA1 matches the key electrical parameters, but it features a different mechanical mounting type (surface mount vs through-hole axial). Mechanical compatibility should be reviewed if direct PCB replacement is required.

Q3: Is there a difference in RoHS compliance between AK 04WS and BAT165E6327HTSA1? A3: AK 04WS is RoHS compliant; BAT165E6327HTSA1 is ROHS3 compliant. Both meet RoHS standards as specified.

Q4: What effect does the package or mounting type have on substitution? A4: AK 04WS uses an axial through-hole package, while BAT165E6327HTSA1 is surface mount. Substitution between these packages affects assembly process and PCB layout. Selection should consider the intended board design.

Q5: Are both parts classified under the same ECCN and HTSUS codes? A5: Yes. Both AK 04WS and BAT165E6327HTSA1 are designated ECCN EAR99 and HTSUS 8541.10.0080 as provided.
