Substitute Part Grouping Explanation

Substitution is determined by matching or exceeding the key parameters that define electrical and mechanical compatibility within the AC/DC converter product category. Substitutes are grouped strictly by:

Output voltage (must match: 3.3V)
Output current (substitute must meet or exceed 2A)
Input voltage range (substitute must include or exceed original input range)
Power rating (substitute must meet or exceed 6.6W)
Number of outputs (must match: 1)
Mounting type and package (must be through-hole module)
Agency approvals and compliance (comparable or broader certification scope)
Operating temperature (substitute must include at least the original range)

Engineering Selection Recommendations

Both PSK-S10C-3 and PSK-10D-3 are listed as active and are compliant with RoHS and REACH requirements. Both are classified as EAR99 for export purposes and share similar standard and approval numbers relevant for household appliances and ITE (commercial) applications. Product selection can proceed based on status as active, relevant approvals, and compliance with environmental and export regulations.

Frequently Asked Questions (FAQ)

Q1: Which parameters must match for a substitute AC/DC converter to be valid?
A1: Output voltage, output current (must meet or exceed), input voltage range (must include the original range), number of outputs, mounting type, and agency approvals/certifications are the primary matching criteria.

Q2: Are there differences in output capabilities between PSK-S10C-3 and PSK-10D-3?
A2: Yes. PSK-10D-3 has a higher maximum output current (2.6A vs. 2A) and higher power rating (8.6 W vs. 6.6 W).

Q3: Can PSK-10D-3 be used in the same applications as PSK-S10C-3?
A3: Based on output voltage, current capability, number of outputs, mounting type, and certification coverage provided, PSK-10D-3 matches the critical criteria for substitution.

Q4: Do enclosure, packaging, or dimensional differences affect direct substitution?
A4: The PSK-10D-3 has a different mechanical size and pinout (6-DIP Module, 4 Leads), so form factor and PCB footprint should be verified for physical compatibility.

Q5: Are both parts compliant with RoHS and REACH requirements?
A5: Both PSK-S10C-3 and PSK-10D-3 are listed as RoHS and REACH compliant.

Q6: What are the temperature ranges for operation?
A6: PSK-S10C-3 operates from -40°C to 70°C (with derating), while PSK-10D-3 operates from -40°C to 85°C (with derating).

Q7: Do both parts have universal AC input ranges?
A7: PSK-10D-3 has a broader AC input range (85 ~ 305 VAC) than PSK-S10C-3 (85 ~ 264 VAC).
