GRM033R70J392KA01D Equivalent & Substitute Parts

Part Overview

The GRM033R70J392KA01D is a 3900 pF ceramic capacitor manufactured by Murata Electronics, rated at 6.3V with X7R temperature coefficient in 0201 (0603 Metric) surface mount package. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is used in general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts are identified when design requirements allow for higher voltage ratings or when inventory constraints necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GRM033R70J392KA01D is permissible when the following conditions are met:

Capacitance value remains 3900 pF with ±10% tolerance. Tolerance specification must match or be tighter than the original part. Temperature coefficient must remain X7R to ensure stable performance across the full operating temperature range of -55°C to 125°C. Voltage rating may be increased above 6.3V provided the circuit design permits higher voltage components. Package and mounting type must remain 0201 (0603 Metric) surface mount to ensure PCB compatibility. Physical dimensions (length, width, thickness) must match the specified tolerances. RoHS3 compliance and MSL 1 rating must be maintained.

The substitute part GRM033R71A392KA01D meets all substitution criteria with the primary difference being an increased voltage rating of 10V, which is acceptable in applications where the original 6.3V rating provides sufficient margin.

Parameter Comparison

Engineering Selection Recommendations

Both the GRM033R70J392KA01D and GRM033R71A392KA01D are Active status products manufactured by Murata Electronics with identical ROHS3 compliance and MSL 1 ratings. The GRM033R71A392KA01D provides a voltage rating upgrade from 6.3V to 10V while maintaining all other electrical and mechanical specifications. Selection between these parts depends on circuit voltage requirements and design margins. The 10V rated substitute is suitable for applications where the original 6.3V specification is adequate, as higher voltage ratings do not degrade performance in lower voltage applications. Both parts maintain identical capacitance, tolerance, temperature coefficient, and physical dimensions, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can GRM033R71A392KA01D replace GRM033R70J392KA01D in all applications?

A: Yes, provided the circuit design permits a 10V rated component. The higher voltage rating does not affect performance in circuits operating below 6.3V. Physical dimensions and electrical characteristics remain identical.

Q: Are there any performance differences between the main part and substitute?

A: No. Both parts share identical capacitance (3900 pF), tolerance (±10%), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and physical dimensions. The only difference is the voltage rating.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both GRM033R70J392KA01D and GRM033R71A392KA01D are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected.

Q: Can the substitute part be used in high-frequency applications?

A: Substitution suitability for high-frequency applications depends on circuit-specific requirements not provided in the component specifications. Consult application-specific design documentation.

Q: Is the 0201 package size identical between both parts?

A: Yes. Both parts use the 0201 (0603 Metric) surface mount package with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm).
