Engineering Selection Recommendations
Selection of PSK-5D-15 as a substitute for PBO-5-S15-B is supported by:
- Matching output voltage and closely matching output current and power rating.
- Both parts satisfy RoHS compliance and share the ECCN and HTSUS classification.
- PSK-5D-15 is Active while PBO-5-S15-B is Obsolete.
- Regulatory approvals and certifications are listed for both, with slight differences in agency and standard coverage.
- Mounting types are through hole for both units, though package/case formats differ.
Frequently Asked Questions (FAQ)
Q: Can PSK-5D-15 directly replace PBO-5-S15-B in existing designs?
A: Direct replacement depends on key matching parameters: output voltage, maximum output current, power rating, input voltage range, and mounting compatibility. The package and lead configuration differ and require mechanical review.
Q: What should be checked for mechanical compatibility?
A: Compare the package dimensions and lead count: PBO-5-S15-B uses a 14-SIP module with 6 leads, PSK-5D-15 uses a 5-DIP module with 4 leads. Board layouts may require modification.
Q: Are approvals and certifications equivalent?
A: Review provided standard numbers and agencies. Both meet the 62368-1 standard, but other certifications differ and must be matched to application requirements.
Q: How do the efficiency and regulation specifications compare?
A: PSK-5D-15 offers higher efficiency (81.5%) and tighter load regulation (±1%) versus PBO-5-S15-B’s 77% efficiency and ±1.5% load regulation.
Q: What is the difference in environmental compliance?
A: Both products are RoHS compliant. PSK-5D-15 states ROHS3 compliance and REACH unaffected status; PBO-5-S15-B offers RoHS compliance with no further detail.
Q: What if the application requires identical mounting and form factor?
A: Examine the package, dimensions, and lead configuration listed in the parameter comparison table before selecting the substitute.
