Key Parameters

Substitute Part Grouping Explanation

Substitution of ceramic capacitors is determined by strict equivalence in the following parameters:

• Capacitance Value: Must be 4.7 µF
• Voltage Rating: Must be 100V or higher
• Package / Case: Must be 1812 (4532 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C
• RoHS and Compliance Status: Must maintain ROHS3 compliance

Tolerance and temperature coefficient variations are permitted within the substitute group, as these parameters define performance characteristics rather than fundamental compatibility. Tolerance tighter than ±20% (such as ±10%) represents an upgrade path. Temperature coefficient differences (X7S vs. X7R) are acceptable substitutes provided the application requirements are met.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Line Integration: C4532X7S2A475K230KB is the recommended upgrade path from C4532X7S2A475M230KB. Both are TDK Corporation products with identical electrical specifications except for improved tolerance (±10% vs. ±20%). The upgrade part maintains Active product status, ensuring long-term availability and supply chain stability. This substitution is direct and requires no design modifications.

For Automotive Applications: CGA8N3X7S2A475M230KB and KTS101B475K43E0T00 are both qualified to AEC-Q200 automotive standards. CGA8N3X7S2A475M230KB maintains TDK manufacturing with identical X7S temperature coefficient. KTS101B475K43E0T00 (Chemi-Con) offers an alternative with X7R temperature coefficient and Active product status, though it has slightly increased maximum thickness (0.110" vs. 0.098").

For Legacy System Support: CGA8N3X7S2A475M230KB provides direct equivalence to the main part with identical electrical and mechanical specifications, suitable for replacement in existing designs where the original part is no longer available.

Frequently Asked Questions (FAQ)

Q: Can C4532X7S2A475K230KB directly replace C4532X7S2A475M230KB? A: Yes. Both parts are identical in capacitance (4.7 µF), voltage rating (100V), temperature coefficient (X7S), package (1812), and operating temperature range (-55°C ~ 125°C). The upgrade part has tighter tolerance (±10% vs. ±20%), which is a performance improvement with no compatibility concerns.

Q: What is the difference between X7S and X7R temperature coefficients? A: Both X7S and X7R are temperature coefficient classifications for ceramic capacitors. X7S specifies ±15% capacitance change over -55°C ~ 125°C. X7R specifies ±15% capacitance change over -55°C ~ 125°C as well. The substitution is valid when application requirements permit either coefficient.

Q: Is KTS101B475K43E0T00 compatible with the original part? A: KTS101B475K43E0T00 is electrically compatible (4.7 µF, 100V, -55°C ~ 125°C, ±10% tolerance). The primary difference is maximum thickness: 0.110" (2.80mm) versus 0.098" (2.50mm) for the original part. Verify PCB layout clearance before substitution.

Q: Why is the main part marked "Not For New Designs"? A: This designation indicates the part has been superseded in the manufacturer's active product line. Existing inventory remains available, but new designs should specify active alternatives such as C4532X7S2A475K230KB or KTS101B475K43E0T00.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, ensuring regulatory and environmental compatibility.
