Substitute Part Grouping Explanation
Substitute part selection for AC/DC converters is determined strictly by matching primary electrical and mechanical parameters:
- Output Voltage (9V)
- Output Power (5W)
- Maximum Output Current (approximate equivalence)
- Number of Outputs (1)
- Input Voltage Range (must cover the original specification)
- Mounting Type (Through Hole)
- Package / Case format
- Regulatory and RoHS/REACH compliance status
Substitutes are grouped based on these key compatibility criteria as explicitly provided.

Engineering Selection Recommendations
Selection of PSK-5D-9 as a substitute is based on full compliance with RoHS and REACH criteria, approval agency listing, and the continued active manufacturing status. Both the main and substitute part are certified to recognized standards within their respective approval agency lists. The substitute covers and exceeds the input voltage range and maintains matching output voltage, current, and power ratings in the same mounting configuration, enabling direct cross-reference by these parameters.
Frequently Asked Questions (FAQ)
Q: What are the primary criteria for selecting a substitute for PSK-S5B-9?
A: Output voltage, power, maximum output current, number of outputs, input voltage range, mounting type, package dimensions, regulatory approvals, and environmental compliance were strictly used to match substitute models.
Q: Is the substitute PSK-5D-9 compatible with the same mounting type as PSK-S5B-9?
A: Both PSK-S5B-9 and PSK-5D-9 utilize through-hole mounting, as specified.
Q: Does the substitute require adjustments to approval or certification processes?
A: PSK-5D-9 holds recognized certifications (CE, cURus) and conforms to regulatory standards explicitly listed in its documentation, matching the compliance status of the main part.
Q: How do package/case formats compare?
A: The main part uses a 26-DIP Module, 5 Leads, while the substitute uses a 5-DIP Module, 4 Leads. Package and lead configuration are listed for direct mechanical comparison.
Q: Are environmental and regulatory requirements comparable between the main and substitute parts?
A: Both PSK-S5B-9 and PSK-5D-9 are RoHS and REACH compliant, and classified under ECCN EAR99.
