Substitute Part Grouping Explanation

Substitution eligibility for the CD5EC510JO3F is determined by matching the following critical electrical and mechanical parameters:

Capacitance Value: 51 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 300 V (exact match required)
Dielectric Material: Mica (exact match required)
Mounting Type: Through Hole (exact match required)
Package Configuration: Radial (exact match required)
Lead Spacing: 0.118" / 3.00 mm (exact match required)
Physical Dimensions: 0.272" L x 0.142" W / 6.90 mm x 3.60 mm (exact match required)

The substitute part CD5EC510JO3 matches all electrical and mechanical parameters with the primary part. Differences in RoHS compliance status and REACH classification do not affect functional equivalence but may impact suitability for specific regulatory environments.

Engineering Selection Recommendations

CD5EC510JO3F is the recommended primary selection for applications requiring ROHS3 compliance and REACH unaffected status. This part is suitable for regulated environments where RoHS certification is mandatory.

CD5EC510JO3 serves as a functional equivalent for applications where RoHS compliance is not required. This substitute provides identical electrical and mechanical performance and is available in higher inventory quantity (1038 units versus 731 units). Selection of this substitute should be limited to applications where RoHS non-compliance and REACH affected status are acceptable.

Both parts are active products from the same manufacturer and series, ensuring consistent quality and performance characteristics. The choice between primary and substitute should be determined by regulatory requirements specific to the end application and target market.

Frequently Asked Questions (FAQ)

Q: Can CD5EC510JO3 be used as a direct replacement for CD5EC510JO3F?

A: CD5EC510JO3 is electrically and mechanically equivalent to CD5EC510JO3F. Both parts have identical capacitance (51 pF), tolerance (±5%), voltage rating (300 V), dielectric material (mica), mounting type (through hole), package configuration (radial), lead spacing (0.118" / 3.00 mm), and physical dimensions. The substitute is suitable for applications where RoHS3 compliance and REACH unaffected status are not required.

Q: What are the differences between CD5EC510JO3F and CD5EC510JO3?

A: The primary differences are regulatory compliance classifications. CD5EC510JO3F is ROHS3 compliant and REACH unaffected, while CD5EC510JO3 is RoHS non-compliant and REACH affected. All electrical parameters, mechanical dimensions, and performance characteristics are identical.

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

A: Yes. Both parts have identical dimensions of 0.272" L x 0.142" W (6.90 mm x 3.60 mm), maximum seated height of 0.209" (5.30 mm), and lead spacing of 0.118" (3.00 mm). They are pin-compatible and occupy the same board space.

Q: Which part should be selected for consumer electronics applications?

A: For consumer electronics applications subject to RoHS regulations, CD5EC510JO3F is the appropriate selection due to its ROHS3 compliance status. CD5EC510JO3 should not be used in applications where RoHS compliance is required.

Q: Are both parts available in the same packaging format?

A: Yes. Both CD5EC510JO3F and CD5EC510JO3 are supplied in bulk packaging as radial through-hole components with identical lead configurations and spacing.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C and are suitable for high-temperature applications within this specification.
