Substitute Part Grouping Explanation

Substitution of the CD5EC300JO3 is permitted with parts that maintain identical electrical specifications and mechanical form factors. The critical parameters governing substitution eligibility are:

• Capacitance value: 30 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 300 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: 0.118" (3.00 mm) (exact match required)
• Physical dimensions: 0.272" L x 0.130" W; 0.201" max height (exact match required)

Parts meeting all these parameters are directly interchangeable. Additional considerations include product compliance status and availability.

Parameter Comparison

Engineering Selection Recommendations

The CD5EC300JO3 and CD5EC300JO3F are functionally equivalent across all electrical and mechanical specifications. Both parts carry Active product status and share identical ECCN and HTSUS classifications.

Selection between these parts should be based on regulatory compliance requirements:

The CD5EC300JO3F is RoHS3 compliant and REACH unaffected, making it the appropriate selection for applications subject to European Union regulations or customer specifications requiring RoHS compliance. The original CD5EC300JO3 is RoHS non-compliant and REACH affected.

Inventory availability favors the CD5EC300JO3F with 2323 pieces in stock compared to 751 pieces for the CD5EC300JO3.

Frequently Asked Questions (FAQ)

Q: Are CD5EC300JO3 and CD5EC300JO3F directly interchangeable? A: Yes. Both parts are identical in capacitance (30 pF), tolerance (±5%), voltage rating (300 V), dielectric material (mica), operating temperature range (-55°C to 125°C), and all mechanical specifications including mounting type, package configuration, lead spacing, and physical dimensions.

Q: What is the primary difference between these parts? A: The CD5EC300JO3F offers RoHS3 compliance and is REACH unaffected, while the CD5EC300JO3 is non-compliant with RoHS and is REACH affected. Both parts are electrically and mechanically identical.

Q: Will either part fit the same PCB footprint? A: Yes. Both parts have identical lead spacing (0.118" / 3.00 mm), physical dimensions (0.272" L x 0.130" W), and maximum seated height (0.201"), ensuring compatibility with the same through-hole mounting pattern.

Q: Which part should be selected for new designs? A: Selection is determined by regulatory requirements. For applications requiring RoHS compliance or REACH compliance, the CD5EC300JO3F is the appropriate choice. Both parts maintain Active product status and are suitable for general purpose applications.

Q: Are there any temperature or voltage derating considerations? A: Both parts operate identically across the -55°C to 125°C temperature range with a 300 V rated voltage. No differential derating applies between the two parts.
