CD5FY301JO3F Equivalent & Substitute Parts

Part Overview

The CD5FY301JO3F is a 300 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CD5 series. This through-hole radial component operates at 50 V rated voltage with ±5% tolerance and is designed for general-purpose applications. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when inventory constraints, compliance requirements, or manufacturing discontinuation necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD5FY301JO3F is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• Capacitance Value: 300 pF (no tolerance variation acceptable)
• Tolerance Grade: ±5% (circuit design dependent)
• Voltage Rating: 50 V (minimum requirement for safe operation)
• Dielectric Type: Mica (electrical performance specification)
• Mounting Configuration: Through Hole Radial (assembly process requirement)
• Lead Spacing: 0.118" / 3.00mm (PCB footprint requirement)
• Operating Temperature Range: -55°C ~ 125°C (environmental specification)

Substitute parts identified within this specification maintain full functional and physical compatibility with the original CD5FY301JO3F design. Variations in compliance certifications (RoHS status, REACH classification) do not affect electrical substitutability but may impact procurement and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The CD5FY301JO3 functions as a parametric equivalent to the CD5FY301JO3F with complete electrical and mechanical compatibility. Both parts are manufactured by Cornell Dubilier Electronics within the CD5 series and maintain identical specifications across all critical performance parameters: 300 pF capacitance, ±5% tolerance, 50 V rating, mica dielectric, through-hole radial mounting, and 3.00mm lead spacing.

Compliance Considerations:

The primary distinction between these parts exists in regulatory compliance status. The CD5FY301JO3F carries ROHS3 compliance certification and REACH Unaffected status, making it suitable for applications subject to European Union environmental directives. The CD5FY301JO3 is RoHS non-compliant and REACH Affected, requiring evaluation against specific procurement and end-use regulations.

Selection between these parts depends on compliance requirements of the target application and market jurisdiction. Both parts maintain identical electrical performance and physical compatibility for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Can CD5FY301JO3 replace CD5FY301JO3F in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both parts are parametrically identical with 300 pF capacitance, ±5% tolerance, 50 V rating, mica dielectric, and identical physical dimensions. Substitution is valid for circuit functionality. Compliance requirements must be evaluated separately based on application jurisdiction and regulatory obligations.

Q: What is the difference between these two part numbers?

A: The parts are electrically and mechanically identical. The difference lies in compliance certifications: CD5FY301JO3F is ROHS3 compliant and REACH Unaffected, while CD5FY301JO3 is RoHS non-compliant and REACH Affected. The suffix designation reflects manufacturing date or compliance batch classification.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions: 0.272" L x 0.169" W (6.90mm x 4.30mm) body size, 0.228" (5.80mm) maximum seated height, and 0.118" (3.00mm) lead spacing. PCB footprints are interchangeable.

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

A: Electrical and mechanical interchangeability is confirmed. High-reliability applications must verify compliance certifications independently. The CD5FY301JO3F with ROHS3 compliance is recommended for regulated markets. The CD5FY301JO3 requires compliance assessment for specific end-use requirements.

Q: What is the lead spacing specification?

A: Lead spacing is 0.118 inches or 3.00 millimeters for both parts. This dimension determines PCB hole pattern and is identical across both part numbers.

Q: Are both parts currently in production?

A: Yes. Both CD5FY301JO3F and CD5FY301JO3 maintain Active product status with current inventory availability (786 pcs and 844 pcs respectively).
