Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LD033C472KAB2A is determined by the following mandatory parameters:

Fixed Parameters (Must Match):

• Capacitance: 4700 pF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage - Rated: May be equal to or greater than 25V
• Manufacturer: Different manufacturers permitted
• Physical dimensions: Minor variations within 0603 package tolerance
• RoHS/REACH compliance status: May differ

All three substitute parts meet these criteria. LD031C472KAB2A provides a voltage upgrade to 100V from the same manufacturer. C0603C472K5RAL7867 (KEMET) and VJ0603Y472KXACW1BC (Vishay Vitramon) both offer 50V ratings with identical capacitance and tolerance specifications in the same 0603 package.

Parameter Comparison

Engineering Selection Recommendations

LD031C472KAB2A (KYOCERA AVX): This substitute provides a voltage rating upgrade from 25V to 100V while maintaining identical capacitance, tolerance, and package specifications. Both parts share the same manufacturer and series designation. This option is suitable when higher voltage margin is required or when KYOCERA AVX supply chain continuity is preferred. RoHS and REACH compliance status remains unchanged from the main part.

C0603C472K5RAL7867 (KEMET): This substitute offers a 50V voltage rating with identical electrical specifications. KEMET is an established manufacturer in the ceramic capacitor market. This part maintains RoHS non-compliant status but achieves REACH Unaffected compliance, providing supply chain flexibility. Physical dimensions show minor variations within 0603 package tolerance (0.031" width vs. 0.032", thickness 0.034" vs. 0.035").

VJ0603Y472KXACW1BC (Vishay Vitramon): This substitute provides 50V voltage rating with identical electrical specifications and achieves ROHS3 Compliant status, offering improved environmental compliance compared to the main part. REACH status is Unaffected. Physical dimensions are consistent with KEMET substitute. Highest inventory availability (78,323 pcs) among all options.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a substitute? A: Yes. A capacitor rated at higher voltage (50V or 100V) can replace the 25V rated LD033C472KAB2A in the same circuit application, provided all other electrical parameters (capacitance, tolerance, temperature coefficient) remain identical. Higher voltage ratings provide additional safety margin.

Q: Are all substitute parts mechanically compatible with the original 0603 package footprint? A: Yes. All substitute parts are specified for 0603 (1608 Metric) package with surface mount configuration. Minor dimensional variations (width 0.031" to 0.032", thickness 0.034" to 0.035") fall within standard 0603 package tolerance and are compatible with standard PCB footprints designed for 0603 components.

Q: What is the difference between RoHS non-compliant and ROHS3 Compliant status? A: RoHS non-compliant parts may contain restricted substances. ROHS3 Compliant parts meet the Restriction of Hazardous Substances Directive requirements. VJ0603Y472KXACW1BC is ROHS3 Compliant, while LD033C472KAB2A, LD031C472KAB2A, and C0603C472K5RAL7867 are RoHS non-compliant.

Q: Does REACH Unaffected status affect component selection? A: REACH Unaffected status indicates the component is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. Both KEMET and Vishay substitutes have REACH Unaffected status, while the main part and KYOCERA AVX upgrade are REACH Affected. Selection depends on supply chain and regulatory requirements.

Q: Can I mix different manufacturers of these capacitors on the same PCB? A: Yes. All substitute parts meet identical electrical specifications (4700 pF, ±10%, X7R, -55°C ~ 125°C) and package requirements (0603 surface mount). Different manufacturers can be used on the same board without functional impact, provided component sourcing and traceability requirements are met.

Q: What is Moisture Sensitivity Level (MSL) 1? A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All parts listed have MSL 1 rating.
