Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based on the following allowed parameters:

Primary Criteria (Must Match):

• Capacitance: 1 pF (exact match required)
• Temperature Coefficient: C0G/NP0 (mandatory for RF/microwave stability)
• Package / Case: 0805 (2012 Metric) (PCB footprint compatibility)
• Mounting Type: Surface Mount, MLCC (assembly process)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

Secondary Criteria (Acceptable Variation):

• Voltage Rating: 250V minimum (higher ratings are acceptable upgrades)
• Tolerance: ±0.1pF or tighter (tighter tolerance is acceptable)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Substitute Categories:

1. Upgrade Substitute – Higher voltage rating with improved tolerance
2. Direct Equivalent – Identical electrical and mechanical specifications from alternative manufacturer
3. Similar Equivalent – Matching core parameters with minor dimensional variation

Engineering Selection Recommendations

CBR08C109ACGAC (KEMET Upgrade Substitute)

This part is a direct upgrade within the KEMET CBR-SMD RF C0G series. It maintains identical physical dimensions and package footprint while providing 500V voltage rating and improved ±0.05pF tolerance. Selection is appropriate for applications requiring higher voltage margin or tighter capacitance tolerance. Both parts share identical operating temperature range, RoHS3 compliance, and MSL 1 rating. No design modification required for PCB assembly.

GQM2195C2E1R0BB12D (Murata Direct Equivalent)

This Murata Electronics part provides electrical and mechanical equivalence to the main part with identical 1 pF capacitance, ±0.1pF tolerance, and 250V rating. Physical dimensions are within 0805 package specification with maximum thickness of 1.00mm. All compliance certifications match (ROHS3, MSL 1). Selection is appropriate for multi-source procurement strategies or when Murata supply chain is preferred.

QSCT251Q1R0B1GV001E (Johanson Technology Similar Equivalent)

This Johanson Technology part meets all core electrical requirements with 1 pF capacitance, ±0.1pF tolerance, and 250V rating in 0805 package. Dimensional variation exists with maximum thickness of 1.17mm compared to 0.95mm for the main part. This thickness difference requires verification of available PCB clearance in high-density layouts. All compliance certifications are equivalent (ROHS3, MSL 1). Selection is appropriate when Johanson supply availability is advantageous and PCB height clearance permits.

Frequently Asked Questions (FAQ)

Q: Can CBR08C109ACGAC replace CBR08C109BAGAC in all applications?

A: Yes. CBR08C109ACGAC is a direct upgrade with higher voltage rating (500V vs 250V) and tighter tolerance (±0.05pF vs ±0.1pF). Identical package, temperature coefficient, and operating range ensure PCB compatibility without design modification. Higher voltage rating provides additional safety margin.

Q: What is the key difference between the KEMET and Murata parts?

A: Both CBR08C109BAGAC and GQM2195C2E1R0BB12D are electrically and mechanically equivalent with identical 1 pF capacitance, ±0.1pF tolerance, and 250V rating in 0805 package. The primary difference is manufacturer. Selection depends on supply chain preference and inventory availability.

Q: Is the Johanson Technology part (QSCT251Q1R0B1GV001E) suitable for my design?

A: QSCT251Q1R0B1GV001E meets all electrical specifications and is electrically equivalent. However, its maximum thickness of 1.17mm exceeds the main part's 0.95mm. Verify available PCB clearance in your layout before selection, particularly in high-density or multi-layer designs with limited vertical space.

Q: Do all substitute parts have the same packaging format?

A: CBR08C109BAGAC and CBR08C109ACGAC are supplied in Tape & Reel (TR) format. GQM2195C2E1R0BB12D is also Tape & Reel. QSCT251Q1R0B1GV001E is supplied in Cut Tape (CT) format. Verify packaging compatibility with your procurement and assembly processes.

Q: Are all parts RoHS3 compliant?

A: Yes. All four parts (CBR08C109BAGAC, CBR08C109ACGAC, GQM2195C2E1R0BB12D, and QSCT251Q1R0B1GV001E) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the tolerance difference between the main part and the upgrade?

A: CBR08C109BAGAC has ±0.1pF tolerance. CBR08C109ACGAC has ±0.05pF tolerance (tighter). For RF and microwave applications, tighter tolerance provides improved circuit accuracy and performance consistency.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, all parts use identical 0805 (2012 Metric) package footprint and surface mount assembly process. Physical dimensions are compatible with standard PCB layouts. The Johanson part has slightly greater thickness; verify clearance in your specific design.
