Substitute Part Grouping Explanation

Substitution of the CD19FD112JO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 1100 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Type: Mica (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Physical Dimensions: Lead spacing 0.343" (8.70 mm), body dimensions 0.650" L x 0.220" W (16.50 mm x 5.60 mm), seated height 0.520" (13.20 mm) (exact match required)
• Temperature Range: -55°C to 125°C (exact match required)

The substitute part CD19FD112JO3F meets all electrical and mechanical parameters identically to the main part, with the distinction of differing compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

CD19FD112JO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material sourcing is permissible. This part maintains active production status and is available in moderate inventory quantities.

CD19FD112JO3F is the appropriate selection for designs requiring ROHS3 compliance and REACH-unaffected material composition. This variant is also in active production with higher inventory availability (1613 units), providing improved supply chain security. Both parts are classified under identical export control (EAR99) and tariff (HTSUS 8532.29.0020) categories.

Selection between these two parts should be based solely on regulatory compliance requirements applicable to the end application and target market.

Frequently Asked Questions (FAQ)

Q: Are CD19FD112JO3 and CD19FD112JO3F electrically identical?

A: Yes. Both parts are 1100 pF mica capacitors with ±5% tolerance, 500 V rating, and identical operating temperature range (-55°C to 125°C). Electrical performance and circuit behavior are equivalent.

Q: Can these parts be used interchangeably on a printed circuit board?

A: Yes. Both parts share identical physical dimensions, lead spacing (0.343" / 8.70 mm), body size (0.650" L x 0.220" W / 16.50 mm x 5.60 mm), and seated height (0.520" / 13.20 mm). PCB footprints and mounting procedures are identical.

Q: What is the primary difference between these two parts?

A: The primary difference is regulatory compliance. CD19FD112JO3F is ROHS3 compliant and REACH unaffected, while CD19FD112JO3 is RoHS non-compliant and REACH affected. Both are manufactured by Cornell Dubilier Electronics in the CD19 series.

Q: Which part should be selected for new designs?

A: Selection depends on applicable regulatory requirements. For applications subject to RoHS3 or REACH restrictions, CD19FD112JO3F is required. For applications without such restrictions, either part is acceptable based on availability and supply chain considerations.

Q: Is inventory availability a factor in part selection?

A: CD19FD112JO3F has higher inventory availability (1613 units) compared to CD19FD112JO3 (972 units). This may influence supply chain planning but does not affect electrical or mechanical compatibility.
