• Identical isolation voltage and regulatory classification (EAR99, HTSUS 8504.31.4035)
• Equivalent REACH compliance status

Frequently Asked Questions (FAQ)

Q: Can the PC-24-50 directly replace the PC-24-50B17 in existing designs?

A: Yes. The PC-24-50 meets all electrical and mechanical specifications of the PC-24-50B17, including primary voltage (115V), dual secondary windings (12V/100mA parallel, 24V/50mA series), power rating (1.2VA), isolation voltage (1500Vrms), mounting type (Through Hole), and termination style (PC Pin). Physical dimensions are equivalent within manufacturing tolerance.

Q: What is the difference in RoHS compliance between the two parts?

A: The PC-24-50B17 carries RoHS Compliant certification, while the PC-24-50 carries ROHS3 Compliant certification. ROHS3 represents the current regulatory standard and indicates enhanced compliance with the latest Restriction of Hazardous Substances directive requirements.

Q: Are there packaging differences between these parts?

A: The PC-24-50B17 is packaged with a dash designation, while the PC-24-50 is packaged in a Box. Both use identical PC Pin termination and Through Hole mounting, ensuring functional compatibility regardless of packaging format.

Q: Why is the PC-24-50B17 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Pulse Electronics. The PC-24-50 from Signal Transformer provides continued access to equivalent transformer functionality with active product status and current regulatory compliance.

Q: Are the physical dimensions identical?

A: Dimensions are equivalent within standard manufacturing tolerance. PC-24-50B17: 34.93mm L × 28.58mm W × 30.18mm H (seated). PC-24-50: 34.90mm L × 28.60mm W × 30.15mm H (seated). These variations fall within acceptable PCB layout and mechanical assembly tolerances.
