Key Parameters

Substitute Part Grouping Explanation

Substitution of CGB3B3JB0J475M055AB is determined by the following critical parameters:

Fixed Parameters (Must Match):

• Capacitance: 4.7 µF
• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm)
• Thickness (Max): 0.022" (0.55mm)
• Manufacturer: TDK Corporation
• Series: CGB
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage - Rated: 6.3V (original) → 10V (substitute acceptable)
• Tolerance: ±20% (original) → ±10% or ±20% (substitute acceptable)
• Temperature Coefficient: JB (original) → JB or X5R (substitute acceptable)
• Operating Temperature: -25°C ~ 85°C (original) → -55°C ~ 85°C (substitute acceptable)

Substitute parts are grouped into two categories: upgrade substitutes (higher voltage rating or improved temperature coefficient) and manufacturer-recommended alternatives (enhanced performance characteristics).

Parameter Comparison

Engineering Selection Recommendations

Direct Tolerance Match (±20%):

• CGB3B1JB1A475M055AC: Maintains ±20% tolerance with upgraded 10V rating and JB temperature coefficient. Suitable for applications requiring higher voltage margin while preserving original tolerance specification.
• CGB3B3X5R0J475M055AB: Maintains ±20% tolerance with X5R temperature coefficient and extended operating range (-55°C ~ 85°C). Recommended for applications requiring improved temperature stability.

Improved Tolerance (±10%):

• CGB3B3JB0J475K055AB: Tighter ±10% tolerance at original 6.3V rating with JB temperature coefficient. Direct performance upgrade maintaining voltage specification.
• CGB3B1JB1A475K055AC: Tighter ±10% tolerance with upgraded 10V rating and JB temperature coefficient.

Manufacturer-Recommended Alternatives (X5R Temperature Coefficient):

• CGB3B1X5R1A475K055AC: ±10% tolerance, 10V rating, X5R coefficient with extended temperature range (-55°C ~ 85°C). Highest inventory availability (156919 Pcs). Recommended for new designs requiring superior temperature stability and extended operating range.
• CGB3B1X5R1A475M055AC: ±20% tolerance, 10V rating, X5R coefficient with extended temperature range. High inventory availability (53509 Pcs).
• CGB3B3X5R0J475K055AB: ±10% tolerance, 6.3V rating, X5R coefficient with extended temperature range. High inventory availability (65541 Pcs). Maintains original voltage specification with improved temperature performance.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical physical dimensions. Selection should be based on application voltage requirements, tolerance specifications, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CGB3B1JB1A475K055AC replace CGB3B3JB0J475M055AB? A: Yes. Both parts share identical capacitance (4.7 µF), package (0603), and mounting type. The substitute offers improved ±10% tolerance and higher 10V voltage rating, making it suitable for applications where the original 6.3V rating is adequate and tighter tolerance is beneficial.

Q: What is the difference between JB and X5R temperature coefficients? A: JB temperature coefficient provides ±15% capacitance change over -25°C ~ 85°C operating range. X5R temperature coefficient provides ±15% capacitance change over -55°C ~ 85°C operating range, extending the lower temperature limit by 30°C. X5R substitutes are recommended for applications requiring extended low-temperature operation.

Q: Is CGB3B1X5R1A475K055AC a direct replacement? A: CGB3B1X5R1A475K055AC is a manufacturer-recommended alternative, not a direct replacement. It maintains 4.7 µF capacitance and 0603 package but upgrades voltage to 10V, improves tolerance to ±10%, and extends operating temperature to -55°C ~ 85°C with X5R coefficient. It is suitable for new designs and applications requiring enhanced performance.

Q: Can I use a 10V rated capacitor in place of a 6.3V rated capacitor? A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible in circuits designed for lower voltage operation. The capacitor will function correctly in applications where the original 6.3V rating was specified.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory certifications.

Q: Which substitute offers the best availability? A: CGB3B1X5R1A475K055AC offers the highest inventory availability at 156919 Pcs. This part combines ±10% tolerance, 10V rating, X5R temperature coefficient, and extended operating range (-55°C ~ 85°C).
