Substitute Part Grouping Explanation

Substitute parts for the CMR03C1R0DOCR are identified based on strict equivalence of the following critical parameters:

Capacitance Value: 1 pF (exact match required)
Tolerance: ±0.5 pF (exact match required)
Voltage Rating: 300 V (exact match required)
Dielectric Material: Mica (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
Mounting Type: Through Hole (exact match required)
Package Configuration: Radial (exact match required)
Lead Spacing: 0.118" (3.00 mm) (exact match required)
Physical Dimensions: 0.272" L x 0.110" W; Height 0.189" max (exact match required)

Engineering Selection Recommendations

CMR03C1R0DOCR is the primary reference part with ROHS3 compliance and REACH Unaffected status, suitable for applications with regulatory compliance requirements.

CD5CC010DO3F provides full electrical and mechanical equivalence with identical ROHS3 compliance and REACH Unaffected status. This part is functionally interchangeable with the CMR03C1R0DOCR and maintains equivalent compliance certifications.

CD5CC010DO3 provides full electrical and mechanical equivalence but carries RoHS non-compliant status and REACH Affected classification. Selection of this part is appropriate only when regulatory compliance is not a design constraint.

All three parts share identical electrical performance, temperature operating range, and mechanical form factor. Selection between them is determined by compliance requirements and regulatory environment of the application.

Frequently Asked Questions (FAQ)

Q: Can CD5CC010DO3 and CD5CC010DO3F be used interchangeably with CMR03C1R0DOCR?

A: CD5CC010DO3F is a direct functional equivalent with identical electrical specifications and compliance status. CD5CC010DO3 is electrically equivalent but differs in RoHS and REACH compliance classifications. Selection depends on regulatory requirements of the application.

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

A: Substitutability is determined by exact equivalence in capacitance (1 pF), tolerance (±0.5 pF), voltage rating (300 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.118" / 3.00 mm), and physical dimensions (0.272" L x 0.110" W, 0.189" max height).

Q: Are there physical compatibility concerns when substituting between these parts?

A: No. All three parts share identical lead spacing (0.118" / 3.00 mm), package dimensions (0.272" L x 0.110" W), and maximum seated height (0.189"). PCB footprints and mechanical mounting are fully compatible.

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

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. RoHS non-compliant status indicates the part does not meet these restrictions. Selection is determined by regulatory requirements of the end application and market region.

Q: How does REACH Affected versus REACH Unaffected status impact part selection?

A: REACH Affected status indicates the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. REACH Unaffected status indicates no such substances are present. Selection depends on regulatory compliance requirements of the application and supply chain.

Q: Are all three parts currently in stock?

A: Yes. CMR03C1R0DOCR has 1045 pcs in stock, CD5CC010DO3 has 758 pcs in stock, and CD5CC010DO3F has 1748 pcs in stock.
