Key Parameters

Substitute Part Grouping Explanation

Substitution for the C1608JB0J106K080AB is determined by the following allowable parameters:

• Capacitance: Must remain 10 µF
• Tolerance: Must remain ±10%
• Package / Case: Must remain 0603 (1608 Metric)
• Mounting Type: Must remain Surface Mount, MLCC
• Physical Dimensions: Must remain 0.063" L x 0.031" W (1.60mm x 0.80mm) and 0.035" (0.90mm) maximum thickness
• RoHS & Compliance: Must maintain ROHS3 Compliant and REACH Unaffected status

Substitutes are grouped into two categories:

Category 1 - Same Temperature Coefficient (JB):

• C1608JB1A106K080AC: Identical temperature coefficient with upgraded voltage rating (10V vs. 6.3V)

Category 2 - Enhanced Temperature Coefficient (X5R):

• C1608X5R0J106K080AB: X5R temperature coefficient with same 6.3V rating; extended operating temperature range (-55°C ~ 85°C)
• C1608X5R1A106K080AC: X5R temperature coefficient with upgraded 10V rating; extended operating temperature range (-55°C ~ 85°C)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): The C1608JB1A106K080AC provides the closest functional equivalent with identical temperature coefficient (JB) and operating temperature range. The sole difference is the elevated voltage rating (10V vs. 6.3V), which is backward compatible for applications operating at or below 6.3V. Both parts maintain Last Time Buy status.

For Long-Term Supply Assurance: The C1608X5R0J106K080AB and C1608X5R1A106K080AC are manufacturer-recommended alternatives with Active product status, ensuring continued availability. These parts feature X5R temperature coefficient with extended operating temperature range (-55°C ~ 85°C vs. -25°C ~ 85°C). The X5R coefficient provides superior temperature stability compared to JB. Both parts are available in high inventory quantities and support extended thermal operating conditions.

Voltage Rating Considerations: Applications designed for 6.3V operation are compatible with 10V-rated substitutes (C1608JB1A106K080AC and C1608X5R1A106K080AC). No circuit modifications are required; the higher voltage rating provides additional design margin.

Compliance Status: All substitute parts maintain ROHS3 Compliant and REACH Unaffected certifications, ensuring regulatory compliance across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can C1608JB1A106K080AC replace C1608JB0J106K080AB directly? A: Yes. Both parts share identical capacitance (10 µF), tolerance (±10%), temperature coefficient (JB), package (0603), and physical dimensions. The C1608JB1A106K080AC has a higher voltage rating (10V vs. 6.3V), which is compatible with circuits designed for 6.3V operation.

Q: What is the difference between JB and X5R temperature coefficients? A: JB and X5R are temperature coefficient classifications defining capacitance variation across temperature ranges. X5R provides a wider operating temperature range (-55°C ~ 85°C) compared to JB (-25°C ~ 85°C) and offers superior temperature stability. Selection depends on application thermal requirements.

Q: Why are C1608X5R0J106K080AB and C1608X5R1A106K080AC marked as Active while the original part is Last Time Buy? A: Active status indicates ongoing production and long-term availability. These X5R variants are manufacturer-recommended alternatives designed to provide supply continuity for applications requiring 10 µF 6.3V or 10V ceramic capacitors in 0603 package.

Q: Are all substitute parts identical in physical dimensions? A: Yes. All parts maintain 0603 (1608 Metric) package specification with dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum thickness of 0.035" (0.90mm). They are mechanically interchangeable on PCBs designed for 0603 components.

Q: Do substitute parts maintain the same moisture sensitivity level? A: Yes. All parts, including substitutes, have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute should I select for new designs? A: For new designs, C1608X5R1A106K080AC is recommended. It combines Active product status for long-term availability, 10V voltage rating for design margin, and X5R temperature coefficient for superior thermal performance across the extended -55°C ~ 85°C operating range.
