Substitute Part Grouping Explanation

Substitutes are selected based strictly on matching or exceeding the essential electrical and mechanical characteristics: input voltage range, output voltage, number of outputs, mounting type, RoHS status, and regulatory certification. Only models explicitly listed as substitutes with validated datasheet parameters comparable or compatible to the PBO-1-S5-B are included. The following key parameters guide all substitution: voltage input range, output voltage, output current, number of outputs, mounting method, operating temperature, efficiency, package dimensions, certification, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The PBO-1-S5-B part is classified as obsolete. The substitute part PBO-3C-5 is active and carries RoHS compliance. Both models are approved by regulatory agencies and offer matching input voltage ranges, output voltage, and mounting type. Differences in certification standards and package dimensions should be reviewed against system requirements to confirm physical compatibility for through hole mounting in related applications.

Frequently Asked Questions (FAQ)

Q1: What parameters are required to select a substitute for PBO-1-S5-B?
A1: Substitute selection is governed by input voltage range, output voltage, number of outputs, output current capability, mounting type, operating temperature, efficiency, package/case, and certification/regulatory compliance.

Q2: Is the output voltage and input range identical between PBO-1-S5-B and PBO-3C-5?
A2: Both PBO-1-S5-B and PBO-3C-5 support a 5V output and accept 85 ~ 305 VAC, 70 ~ 430 VDC input ranges.

Q3: Can the substitute PBO-3C-5 deliver higher output current than PBO-1-S5-B?
A3: Yes, PBO-3C-5 supports up to 600mA output compared to PBO-1-S5-B’s 200mA maximum.

Q4: Are there differences in physical package and size?
A4: PBO-3C-5 uses a 6-SIP module with smaller dimensions than the 12-SIP module of PBO-1-S5-B. Review for footprint compatibility.

Q5: Do both converters meet RoHS compliance?
A5: Both models are RoHS compliant.

Q6: What considerations apply to mounting type?
