CD19FA103JO3F Equivalent & Substitute Parts Reference

Part Overview

The CD19FA103JO3F is a 10000 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CD19 series. This through-hole radial component operates at 100 V rated voltage with ±5% tolerance and is designed for general-purpose applications across an operating temperature range of -55°C to 125°C. The part is currently active in production status with 736 units in stock. Mica capacitors of this specification are essential in applications requiring stable capacitance, low loss, and reliable performance in demanding environmental conditions. Identifying equivalent and substitute parts becomes necessary when managing inventory constraints, addressing supply chain variations, or accommodating design flexibility within established electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD19FA103JO3F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (10000 pF), tolerance (±5%), and rated voltage (100 V) must match exactly. The dielectric material must remain mica to preserve the electrical characteristics and performance profile of the original specification.

Mechanical Parameters: Mounting type (through hole), package configuration (radial), lead spacing (0.343" / 8.70mm), and physical dimensions (0.720" L x 0.370" W / 18.30mm x 9.40mm) must be identical to ensure direct board-level compatibility without layout modifications.

Environmental Parameters: Operating temperature range (-55°C to 125°C) must be maintained to support the intended application environment.

Series Designation: Parts must belong to the CD19 series to maintain manufacturer consistency and design validation.

Substitute parts identified within this reference are limited to those meeting all stated parameters. No extrapolation beyond provided specifications is applied.

Parameter Comparison

Engineering Selection Recommendations

The CD19FA103JO3 is electrically and mechanically equivalent to the CD19FA103JO3F across all functional parameters. Both parts deliver identical capacitance, voltage rating, tolerance, temperature performance, and physical form factor.

Compliance Considerations: The main part CD19FA103JO3F carries ROHS3 compliance and REACH Unaffected status. The substitute part CD19FA103JO3 is RoHS non-compliant and REACH Affected. Selection between these parts must account for end-application regulatory requirements. Applications subject to RoHS3 or REACH restrictions require the CD19FA103JO3F. Applications without such constraints may utilize either part based on availability and inventory position.

Inventory Availability: The CD19FA103JO3 maintains higher stock levels (890 units) compared to the CD19FA103JO3F (736 units), which may influence procurement decisions when supply continuity is a priority.

Both parts are active in production status, ensuring continued availability for future procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can the CD19FA103JO3 be used as a direct replacement for the CD19FA103JO3F in all applications?

A: The CD19FA103JO3 is electrically and mechanically equivalent. However, regulatory compliance differs. Use CD19FA103JO3F in applications requiring RoHS3 compliance or REACH Unaffected status. Use CD19FA103JO3 only in applications without such regulatory constraints.

Q: What are the critical parameters that define substitution eligibility for this mica capacitor?

A: Substitution requires exact matching of capacitance (10000 pF), tolerance (±5%), voltage rating (100 V), dielectric material (mica), mounting type (through hole), package configuration (radial), lead spacing (0.343" / 8.70mm), physical dimensions (0.720" L x 0.370" W), and operating temperature range (-55°C to 125°C).

Q: Are there dimensional differences between the main part and substitute?

A: No. Both parts share identical physical dimensions: 0.720" L x 0.370" W (18.30mm x 9.40mm) with maximum seated height of 0.598" (15.20mm) and lead spacing of 0.343" (8.70mm). Direct board-level substitution is supported without layout modification.

Q: What is the difference between ROHS3 Compliant and RoHS non-compliant status?

A: ROHS3 Compliant indicates the part meets Restriction of Hazardous Substances Directive 3 requirements, restricting specific hazardous materials. RoHS non-compliant indicates the part does not meet these restrictions. Selection depends on end-product regulatory requirements and target markets.

Q: What does REACH Unaffected versus REACH Affected mean?

A: REACH Unaffected indicates the part is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. REACH Affected indicates the part falls under REACH regulations. Applications subject to REACH compliance require REACH Unaffected parts.

Q: Can I mix CD19FA103JO3F and CD19FA103JO3 parts in the same production batch?

A: Mixing is not recommended if regulatory compliance documentation or traceability requires consistent compliance status across all components. Maintain separate inventory and procurement streams to ensure compliance consistency.

Q: What is the lead spacing and how does it affect board compatibility?

A: Lead spacing is 0.343" (8.70mm), measured center-to-center between the two radial leads. This spacing determines PCB hole pattern compatibility. Both substitute parts maintain identical lead spacing, ensuring direct compatibility with existing board designs.
