Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM04FA331JO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 330 pF
• Tolerance: ±5%
• Voltage - Rated: 100 V
• Dielectric Material: Mica

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.142" (3.60 mm)
• Size / Dimension: 0.390" L x 0.220" W (9.90 mm x 5.60 mm)
• Height - Seated (Max): 0.370" (9.40 mm)

Environmental Parameters (Must Match Exactly):

• Operating Temperature Range: -55°C to 125°C

The CM04FA331JO3 belongs to the CM04 series. Substitute parts identified are from the CD10 series (CD10FA331JO3 and CD10FA331JO3F), which maintain identical electrical and mechanical specifications while differing in regulatory compliance status. Both substitute parts satisfy all substitution criteria and are functionally equivalent for circuit applications.

Parameter Comparison

Engineering Selection Recommendations

CM04FA331JO3 (Original Part): Use when the application requires RoHS non-compliant components or when existing inventory of the CM04 series is preferred. This part is Active status and suitable for general-purpose applications within the specified electrical and thermal parameters.

CD10FA331JO3 (Substitute - RoHS Non-Compliant): This part provides functional equivalence to the CM04FA331JO3 with identical electrical and mechanical specifications. It is classified as Active status and maintains REACH Affected regulatory status. Use when CD10 series inventory is available and RoHS compliance is not a design requirement.

CD10FA331JO3F (Substitute - RoHS3 Compliant): This part provides functional equivalence with ROHS3 Compliant certification and REACH Unaffected status. Use when regulatory compliance with RoHS3 and REACH requirements is mandated by design specifications or customer requirements. This part has the highest available inventory (1154 Pcs) and is recommended for new designs requiring environmental compliance.

All three parts are electrically and mechanically interchangeable for through-hole PCB applications requiring 330 pF, 100 V mica capacitors with radial lead configuration.

Frequently Asked Questions (FAQ)

Q: Can CM04FA331JO3 be directly replaced with CD10FA331JO3 or CD10FA331JO3F?

A: Yes. All three parts share identical electrical specifications (330 pF, ±5%, 100 V), dielectric material (Mica), and mechanical dimensions (radial, 0.142" lead spacing, 0.390" L x 0.220" W). Direct substitution is functionally valid for circuit operation.

Q: What is the difference between CD10FA331JO3 and CD10FA331JO3F?

A: Both parts are electrically and mechanically identical. The primary difference is regulatory compliance: CD10FA331JO3F is ROHS3 Compliant and REACH Unaffected, while CD10FA331JO3 is RoHS non-compliant and REACH Affected. Select CD10FA331JO3F for applications requiring environmental compliance certifications.

Q: Are there any physical differences between these parts?

A: No. All three parts have identical physical dimensions: 0.390" L x 0.220" W (9.90 mm x 5.60 mm), maximum seated height of 0.370" (9.40 mm), and lead spacing of 0.142" (3.60 mm). They are mechanically interchangeable on PCBs designed for radial through-hole capacitors.

Q: What operating temperature range applies to all substitute parts?

A: All parts operate across -55°C to 125°C. This temperature range is identical across CM04FA331JO3, CD10FA331JO3, and CD10FA331JO3F.

Q: Which part should be selected for new designs?

A: CD10FA331JO3F is recommended for new designs due to ROHS3 Compliant status and REACH Unaffected certification, combined with the highest inventory availability (1154 Pcs). This ensures compliance with current environmental regulations and supply chain continuity.

Q: Are all parts rated for 100 V operation?

A: Yes. All three parts are rated at 100 V. Voltage rating is identical across CM04FA331JO3, CD10FA331JO3, and CD10FA331JO3F.

Q: What is the tolerance specification for these capacitors?

A: All parts maintain ±5% capacitance tolerance, ensuring consistent performance across the 330 pF nominal value (range: 313.5 pF to 346.5 pF).
