Engineering Selection Recommendations

Both CD42FD473GO3 and CD42FD473GO3F are functionally equivalent 0.047 µF mica capacitors with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory and compliance requirements:

CD42FD473GO3 is suitable for applications where RoHS compliance is not mandated and REACH-affected material usage is acceptable. This part maintains full compatibility with legacy designs and systems without RoHS requirements.

CD42FD473GO3F is the appropriate selection for applications requiring ROHS3 compliance and REACH-unaffected material composition. This variant is required for new designs, products destined for markets with RoHS mandates, and systems where regulatory compliance documentation is necessary.

Both parts share identical ECCN (EAR99) and HTSUS (8532.29.0020) classifications. Functional performance, thermal characteristics, and electrical behavior are identical across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Are CD42FD473GO3 and CD42FD473GO3F electrically interchangeable?

A: Yes. Both parts are electrically identical with 0.047 µF capacitance, ±2% tolerance, 500 V rating, and mica dielectric. They perform identically in all circuit applications.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts have identical physical dimensions (1.469" L x 0.449" W), lead spacing (1.063" / 27.00 mm), and radial through-hole mounting configuration. They occupy the same footprint and require no PCB modifications.

Q: What is the difference between these two part numbers?

A: The primary differences are regulatory compliance status. CD42FD473GO3F is ROHS3 compliant and REACH unaffected, while CD42FD473GO3 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.
