Key Parameters

Substitute Part Grouping Explanation

Substitution is established by strict comparison of key electrical and mechanical parameters: output voltage (12V), output current (420mA), power rating (5W), input voltage range, mounting type, package/case dimensions, and compliance with relevant safety and quality standards. Only products matching these parameters and compliance documentation are considered substitutes.

Parameter Comparison

Engineering Selection Recommendations

PBO-5-S12 is listed as obsolete. Substitution with PBO-5C-12 is established based on matching output voltage, output current, power rating, mounting type, RoHS compliance status, and regulatory approvals specific to each part. Certifying agencies and listed standards should be verified for alignment with end product safety certifications and application regulatory requirements.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters that enable substitution between PBO-5-S12 and PBO-5C-12?
A1: Critical substitution parameters are output voltage (12V), output current (420mA), power rating (5W), electrical input range compatibility, mechanical mounting type, package/case format, and RoHS compliance.

Q2: Do package and mounting differences affect direct replacement?
A2: Both parts utilize through-hole mounting; however, package/case dimensions and configuration differ. Mechanical and PCB layout compatibility should be verified based on published dimensions.

Q3: Are both models compliant with RoHS and relevant standards?
A3: Both PBO-5-S12 and PBO-5C-12 are RoHS compliant and have specified regulatory approvals and standards. The substitute’s listed standards and certifications should meet end-product or application requirements.

Q4: Can substitute parts operate in the same temperature range?
A4: The operating temperature range for PBO-5C-12 extends lower than PBO-5-S12. The upper temperature derating limit for both is 85°C.

Q5: Is there any difference in use-case or application category?
A5: PBO-5-S12 is specified for ITE (Commercial). PBO-5C-12 supports both household appliances and ITE (Commercial). Application category should match the regulatory needs of the intended use.
