Substitute Part Grouping Explanation
Substitution is based strictly on matching or exceeding the key electrical and mechanical parameters: input voltage range, output voltage, output current, number of outputs, mounting type, package/case, operating temperature, and compliance certifications. Only parts that meet these criteria, as explicitly stated, are grouped for substitution. For PBO-1-S15, substitute parts must provide a 15V single output, operate within the input voltage range specified, support the required mounting type and package, and hold equivalent or stronger compliance and certification status.

Engineering Selection Recommendations
The PBO-1-S15 part is listed as obsolete, requiring the selection of an alternative with equal or improved compliance and certification status. The recommended substitute, PBO-3C-15, is active and holds RoHS compliance. Both parts support through hole mounting and include necessary agency approvals and standard numbers. The substitute maintains compatibility with the key electrical parameters, including input voltage, output voltage, and operating temperature.
Frequently Asked Questions (FAQ)
Q1: What are the primary criteria for selecting a substitute for PBO-1-S15?
A1: Substitute selection is based exclusively on matching input voltage range, output voltage, output current (must meet or exceed), number of outputs, mounting type, package/case, operating temperature, and compliance certifications.
Q2: Does the PBO-3C-15 offer the same output voltage as the PBO-1-S15?
A2: Yes, both PBO-1-S15 and PBO-3C-15 provide a single output of 15V.
Q3: Are there any differences in package or mechanical footprint between PBO-1-S15 and its substitute?
A3: PBO-1-S15 is specified as a 12-SIP Module, 6 Leads, whereas PBO-3C-15 is listed as a 6-SIP Module. Size and lead configuration should be reviewed for compatibility in the intended application.
Q4: Are both parts compliant with RoHS standards?
A4: Yes, both PBO-1-S15 and PBO-3C-15 are RoHS Compliant.
Q5: Is the substitute, PBO-3C-15, suitable for the same operating temperature range?
A5: Yes, both parts specify an operating temperature of -40°C to 85°C (with derating).
Q6: Does the substitute provide higher output current or power ratings?
A6: PBO-3C-15 supports up to 200mA output current and 3W power, exceeding the 67mA and 1W parameters of PBO-1-S15.
