Substitute Part Grouping Explanation

Substitution of the CM05ED820JO3 is determined by strict equivalence across the following critical parameters:

Capacitance Value: 82 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 500 V (exact match required)
Dielectric Material: Mica (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
Mounting Type: Through Hole (exact match required)
Package Configuration: Radial (exact match required)
Lead Spacing: 0.232" (5.90 mm) (exact match required)
Physical Dimensions: 0.449" L x 0.181" W, Height 0.358" max (exact match required)

All identified substitute parts meet these criteria. Variations in RoHS compliance status, REACH classification, and MSL rating do not affect electrical or mechanical interchangeability but may influence suitability for specific regulatory environments or end applications.

Engineering Selection Recommendations

CM05ED820JO3 (Original Part)

The CM05ED820JO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material status does not present regulatory constraints. This part is Active and maintains adequate inventory levels.

CD15ED820JO3 (Parametric Equivalent)

The CD15ED820JO3 provides direct electrical and mechanical equivalence to the CM05ED820JO3 while maintaining identical performance characteristics. This substitute shares the same RoHS non-compliant and REACH-affected status as the original part. Inventory availability is higher at 2496 units, supporting supply chain continuity.

CD15ED820JO3F (Parametric Equivalent with Enhanced Compliance)

The CD15ED820JO3F is electrically and mechanically identical to the CM05ED820JO3 and CD15ED820JO3 but carries ROHS3 compliance certification and REACH-unaffected status. This variant is required for applications subject to RoHS3 regulations or REACH restrictions. Inventory is available at 869 units.

Selection between these three parts depends solely on regulatory compliance requirements mandated by the end application or regional market. All three parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the CM05ED820JO3, CD15ED820JO3, and CD15ED820JO3F electrically interchangeable?

A: Yes. All three parts share identical electrical specifications: 82 pF capacitance, ±5% tolerance, 500 V rating, mica dielectric, and -55°C to 125°C operating temperature range. They perform identically in circuit applications.

Q: Are these parts mechanically interchangeable?

A: Yes. All three parts feature identical mechanical specifications: radial through-hole mounting, 0.232" (5.90 mm) lead spacing, 0.449" L x 0.181" W body dimensions, and 0.358" maximum seated height. They mount identically on PCBs with the same footprint.

Q: What is the difference between the three parts?

A: The primary differences are RoHS compliance status and REACH classification. The CM05ED820JO3 and CD15ED820JO3 are RoHS non-compliant and REACH-affected. The CD15ED820JO3F is ROHS3 compliant and REACH-unaffected. These differences do not affect electrical or mechanical performance.

Q: Which part should I select for RoHS3-regulated applications?

A: The CD15ED820JO3F is the only variant with ROHS3 compliance certification and is required for applications subject to RoHS3 regulations.

Q: Which part should I select for REACH-restricted applications?

A: The CD15ED820JO3F is REACH-unaffected and is suitable for applications with REACH material restrictions. The CM05ED820JO3 and CD15ED820JO3 are REACH-affected and may not be suitable depending on application requirements.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, provided regulatory compliance requirements are met. All three parts have identical footprints, lead spacing, and mounting requirements. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What is the inventory status for each part?

A: CM05ED820JO3 has 925 units in stock, CD15ED820JO3 has 2496 units, and CD15ED820JO3F has 869 units available.
