CD5FA181JO3 Equivalent & Substitute Parts

Part Overview

The CD5FA181JO3 is a 180 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CD5 series. This through-hole radial capacitor 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 with 658 units in stock. Identifying equivalent substitute parts is necessary when the original part becomes unavailable, when compliance requirements change, or when inventory constraints require alternative sourcing from the same manufacturer's product line.

Substitute Part Grouping Explanation

Substitute parts for the CD5FA181JO3 are identified based on strict parametric equivalence. The following electrical and mechanical parameters must match identically for a part to function as a direct substitute:

• Capacitance value: 180 pF
• Tolerance: ±5%
• Rated voltage: 100 V
• Dielectric material: Mica
• Operating temperature range: -55°C to 125°C
• Mounting type: Through Hole
• Package type: Radial
• Lead spacing: 0.118" (3.00 mm)
• Physical dimensions: 0.272" L x 0.181" W (6.90 mm x 4.60 mm)
• Maximum seated height: 0.240" (6.10 mm)

The CD5FA181JO3F is identified as a parametric equivalent within the CD5 series. This substitute maintains all electrical specifications and mechanical dimensions required for direct board-level replacement. The primary distinction between the original part and its substitute relates to compliance certifications and product status, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

The CD5FA181JO3F serves as a direct parametric substitute for the CD5FA181JO3 in applications where all electrical and mechanical specifications are identical. Both parts are active products from Cornell Dubilier Electronics within the CD5 series and maintain identical functional performance characteristics.

The primary distinction between these parts is regulatory compliance status. The CD5FA181JO3F achieves ROHS3 compliance, whereas the CD5FA181JO3 is RoHS non-compliant. Additionally, the CD5FA181JO3F is REACH Unaffected, while the original part is REACH Affected. These compliance differences are significant for applications subject to European Union regulations or customer-mandated environmental standards.

Selection between these parts should be based on the specific compliance requirements of the end application and target market. Both parts are suitable for general-purpose through-hole applications requiring 180 pF capacitance at 100 V with ±5% tolerance across the -55°C to 125°C operating range. The CD5FA181JO3F offers higher current inventory availability at 891 units compared to 658 units for the original part.

Frequently Asked Questions (FAQ)

Q: Can the CD5FA181JO3F be used as a direct replacement for the CD5FA181JO3 on a printed circuit board?

A: Yes. The CD5FA181JO3F is a parametric equivalent with identical electrical specifications (180 pF, ±5%, 100 V), dielectric material (mica), mounting type (through-hole radial), and physical dimensions (0.272" L x 0.181" W, 0.118" lead spacing, 0.240" maximum seated height). Direct board-level substitution is supported without circuit modification.

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

A: The electrical and mechanical specifications are identical. The differences are compliance-related: the CD5FA181JO3F is ROHS3 compliant and REACH Unaffected, while the CD5FA181JO3 is RoHS non-compliant and REACH Affected. Both parts are active products in the CD5 series.

Q: Are there any temperature or voltage derating considerations when substituting between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and share the same 100 V rated voltage specification. No derating adjustments are required.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance or REACH compliance, the CD5FA181JO3F is the appropriate choice. Both parts are active and available from Cornell Dubilier Electronics.

Q: Is the lead spacing identical between these parts?

A: Yes. Both parts have 0.118" (3.00 mm) lead spacing and are packaged as radial through-hole components with identical physical dimensions.
