Parameter Comparison

Engineering Selection Recommendations

CD15CD120JO3F is the primary substitute for applications requiring regulatory compliance. This part maintains identical electrical and mechanical specifications while offering ROHS3 compliance and REACH unaffected status, making it suitable for designs subject to environmental regulations.

CM05CD120JO3 is a functional equivalent from the CM05 series. It matches all critical electrical and mechanical parameters and is suitable for general-purpose applications where the CD15 series is not available. This part carries REACH Affected status and RoHS non-compliant classification, consistent with the original CD15CD120JO3.

All three parts are active products with confirmed inventory availability and are interchangeable based on electrical performance and physical form factor.

Frequently Asked Questions (FAQ)

Q: Can CD15CD120JO3F replace CD15CD120JO3 in existing designs?

A: Yes. CD15CD120JO3F is a direct substitute with identical capacitance (12 pF), tolerance (±5%), voltage rating (500 V), and physical dimensions. The primary difference is improved regulatory compliance (ROHS3 Compliant and REACH Unaffected status).

Q: What is the difference between CD15CD120JO3 and CM05CD120JO3?

A: Both parts share identical electrical specifications (12 pF, ±5%, 500 V) and mechanical form factors (radial, through-hole, 0.232" lead spacing). The difference is the product series designation (CD15 versus CM05). Both are functionally equivalent for circuit applications.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts have identical dimensions: 0.449" L x 0.169" W (11.40mm x 4.30mm) with maximum seated height of 0.358" (9.10mm) and lead spacing of 0.232" (5.90mm). They are mechanically interchangeable on PCBs designed for radial mica capacitors.

Q: Which substitute should be selected for new designs?

A: CD15CD120JO3F is recommended for new designs due to ROHS3 compliance and REACH unaffected status. CM05CD120JO3 is suitable when CD15 series availability is limited or when regulatory requirements do not mandate RoHS3 compliance.

Q: Do all parts operate across the same temperature range?

A: Yes. All three parts operate from -55°C to 125°C, ensuring thermal compatibility in equivalent circuit applications.
