Substitute Part Grouping Explanation

Substitution of the CGB4B3JB1E105M055AB is determined by strict equivalence in the following parameters: capacitance value (1 µF), rated voltage (25V), package type (0805), and mounting configuration (Surface Mount, MLCC). Tolerance and temperature coefficient variations are permitted substitution criteria when the application requirements allow.

The substitute parts are grouped into two categories:

Tolerance Upgrade (±20% to ±10%): CGB4B3JB1E105K055AB maintains identical temperature coefficient (JB) and operating temperature range while improving tolerance specification.

Temperature Coefficient Enhancement (JB to X5R): CGB4B3X5R1E105K055AB and CGB4B3X5R1E105M055AB extend the operating temperature range to -55°C ~ 85°C through X5R temperature coefficient, with tolerance variations of ±10% and ±20% respectively.

All substitute parts maintain identical capacitance, voltage rating, package dimensions, and compliance certifications (ROHS3, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full compliance with ROHS3 and REACH Unaffected status, ensuring regulatory alignment with the original CGB4B3JB1E105M055AB specification.

CGB4B3JB1E105K055AB provides direct substitution with improved tolerance (±10% versus ±20%) while maintaining identical temperature coefficient and operating range. This part is suitable for applications where tighter capacitance tolerance is beneficial without requiring extended low-temperature performance.

CGB4B3X5R1E105K055AB and CGB4B3X5R1E105M055AB extend the operating temperature range to -55°C ~ 85°C through X5R temperature coefficient. These parts are appropriate for applications requiring enhanced low-temperature stability. CGB4B3X5R1E105K055AB offers ±10% tolerance, while CGB4B3X5R1E105M055AB maintains ±20% tolerance matching the original specification.

All parts are available in standard packaging configurations (Cut Tape or Tape & Reel) and share identical physical dimensions and mounting characteristics, ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can CGB4B3JB1E105K055AB be used as a direct replacement for CGB4B3JB1E105M055AB?

A: Yes. Both parts share identical capacitance (1 µF), voltage rating (25V), temperature coefficient (JB), operating temperature range (-25°C ~ 85°C), and package dimensions (0805). The tolerance improvement from ±20% to ±10% represents an upgrade in specification accuracy.

Q: What is the difference between JB and X5R temperature coefficients?

A: JB temperature coefficient operates across -25°C ~ 85°C, while X5R extends the operating range to -55°C ~ 85°C. X5R provides enhanced stability across a wider temperature spectrum. Selection depends on application temperature requirements.

Q: Are the physical dimensions identical across all substitute parts?

A: Yes. All parts are packaged in 0805 (2012 Metric) with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum thickness of 0.022" (0.55mm), ensuring direct PCB compatibility.

Q: What packaging options are available for these substitute parts?

A: CGB4B3JB1E105K055AB is available in Cut Tape (CT). CGB4B3X5R1E105K055AB is available in Tape & Reel (TR). CGB4B3X5R1E105M055AB is available in Cut Tape (CT) and Digi-Reel®. Selection depends on procurement and assembly requirements.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. All parts are ROHS3 Compliant and REACH Unaffected with Moisture Sensitivity Level 1 (Unlimited), matching the original part's regulatory status.
