Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly determined by matched key parameters: output characteristics (voltage, current, power), input voltage range, mechanical mounting type, compliance status, and relevant safety certifications. Alternative models included here are based on identical or extended electrical and mechanical specifications, series compatibility, and RoHS compliance, referenced directly from available manufacturer data. Parameters used for grouping are:

• Output voltage, current, and power rating
• Input voltage range
• Mounting type
• Package type
• Safety and environmental compliance (RoHS, agency approvals)
• Product status (active or obsolete)

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute AC/DC converters should be based on product status (preferably active models), regulatory compliance (such as RoHS), and confirmed safety agency approvals. The substitute part PBO-5C-5 maintains compatibility with key output specifications and environmental standards. Approval agency and standard numbers must be reviewed for system certification alignment.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting PBO-5-S5? A1: Primary criteria include identical output voltage, output current, total power, input voltage range, mounting type, package compatibility, and compliant safety/environmental certifications.

Q2: Is the package of PBO-5C-5 mechanically identical to PBO-5-S5? A2: The main dimensions and mounting type are similar (through-hole SIP modules), but the number of leads, size, and specific mechanical format differ. Verification against PCB layout requirements is necessary.

Q3: Will the substitute part provide the same electrical performance? A3: The substitute part PBO-5C-5 offers matching output voltage, current, and power ratings. Input voltage range is broader, ensuring electrical specification compatibility.

Q4: Are regulatory approvals directly interchangeable? A4: Both devices are RoHS compliant, but safety and EMC standards and approval agencies differ. Review of system-level certification requirements is required to confirm full compliance.

Q5: Can PBO-5C-5 be installed in existing designs for PBO-5-S5? A5: Installation feasibility depends on matching mounting type and package dimensions. Engineering assessment of PCB footprint compatibility is recommended.
