Engineering Selection Recommendations

Primary Selection: CMR03F331JOYR

The CMR03F331JOYR is the preferred selection for applications requiring ROHS3 compliance and REACH unaffected status. This part is Active product status with full regulatory alignment for markets with strict environmental compliance requirements.

Substitute Selection: CD5FY331JO3

The CD5FY331JO3 is electrically and mechanically equivalent to the CMR03F331JOYR and is suitable for substitution in applications where RoHS3 compliance and REACH unaffected status are not mandatory requirements. This part is Active product status and maintains identical electrical performance, temperature range, and physical form factor. The CD5FY331JO3 is classified as RoHS non-compliant and REACH Affected; selection of this substitute requires confirmation that the end application and market do not impose these compliance restrictions.

Both parts are manufactured by Cornell Dubilier Electronics (CDE) and share identical core electrical and mechanical specifications, ensuring functional interchangeability within the stated parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can CD5FY331JO3 be used as a direct replacement for CMR03F331JOYR in all applications?

A: CD5FY331JO3 is electrically and mechanically equivalent to CMR03F331JOYR. Substitution is valid for applications where RoHS3 compliance and REACH unaffected status are not required. Applications subject to RoHS3 or REACH regulations must use CMR03F331JOYR.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance (330 pF), tolerance (±5%), voltage rating (50 V), and dielectric material (Mica) must be identical. Both parts meet these requirements.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both CMR03F331JOYR and CD5FY331JO3 share identical dimensions (0.272" L x 0.181" W), lead spacing (0.118" / 3.00mm), and maximum seated height (0.240" / 6.10mm). Both are radial through-hole packages suitable for standard PCB mounting.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 125°C. This range is identical for CMR03F331JOYR and CD5FY331JO3.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts are rated MSL 1 (Unlimited), indicating minimal moisture sensitivity and no special storage or handling requirements.

Q: What compliance differences exist between the two parts?
