Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Critical Parameters (Must Match):

Capacitance: 2.2 pF
Temperature Coefficient: C0G/NP0
Package: 0805 (2012 Metric)
Mounting Type: Surface Mount, MLCC
Operating Temperature Range: -55°C ~ 125°C
RoHS Status: ROHS3 Compliant

Allowable Variations:

Voltage Rating: Equal to or greater than 50V
Tolerance: ±0.1pF or ±0.25pF (both acceptable)
Manufacturer: Different manufacturers permitted if all electrical and mechanical parameters align
Packaging Format: Tape & Reel (TR) or Cut Tape (CT) acceptable

Substitute parts are grouped into three categories based on parameter alignment:

Upgrade Substitutes – Parts with improved tolerance (±0.1pF) or higher voltage rating (100V, 200V) while maintaining all other specifications.

Parametric Equivalents – Parts with identical electrical specifications but different packaging format or series designation.

Direct Equivalents – Parts from alternative manufacturers with identical or superior specifications and same package format.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original 08055A2R2CAT2M.

For Direct Replacement (Identical Specifications): KGM21BCG1H2R2CT (KYOCERA AVX) provides parametric equivalence with identical electrical specifications and higher inventory availability (20,367 pcs). C0805C229C5GAC7800 (KEMET) and VJ0805A2R2CXACW1BC (Vishay Vitramon) offer cross-manufacturer alternatives with matching specifications.

For Enhanced Performance (Improved Tolerance): KGM21BCG1H2R2BT (KYOCERA AVX) and CC0805BRNPO9BN2R2 (YAGEO) provide ±0.1pF tolerance at 50V, suitable for applications requiring tighter capacitance control.

For Higher Voltage Margin: KGM21BCG2A2R2CT (KYOCERA AVX) with 100V rating and 26,683 pcs inventory provides voltage headroom while maintaining ±0.25pF tolerance. C0805C229C1GAC7800 (KEMET) at 100V and C0805C229C2GAC7800 (KEMET) at 200V offer additional voltage ratings from an alternative manufacturer.

All substitutes are Surface Mount MLCC components in 0805 package with -55°C to 125°C operating range and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can KGM21BCG1H2R2BT replace 08055A2R2CAT2M directly? A: Yes. Both parts share identical capacitance (2.2 pF), voltage rating (50V), temperature coefficient (C0G/NP0), and 0805 package. KGM21BCG1H2R2BT offers improved ±0.1pF tolerance versus ±0.25pF of the original part.

Q: What is the difference between 50V and 100V rated parts? A: Voltage rating indicates maximum operating voltage. A 100V-rated capacitor (KGM21BCG2A2R2BT, KGM21BCG2A2R2CT, C0805C229C1GAC7800) can be used in 50V circuits with additional voltage margin. The 50V-rated original part cannot be substituted into 100V circuits.

Q: Are KEMET and YAGEO parts compatible with KYOCERA AVX designs? A: Yes, when electrical and mechanical parameters are identical. C0805C229C5GAC7800 (KEMET), CC0805CRNPO9BN2R2 (YAGEO), and VJ0805A2R2CXACW1BC (Vishay Vitramon) maintain the same capacitance, tolerance, voltage, temperature coefficient, and 0805 package format.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance? A: No. Packaging format affects handling and assembly logistics only. Tape & Reel (TR) and Cut Tape (CT) formats contain identical components with the same electrical specifications.

Q: What does ±0.1pF tolerance mean compared to ±0.25pF? A: Tolerance defines the allowable capacitance deviation from the nominal 2.2 pF value. ±0.1pF tolerance (tighter) ranges 2.1–2.3 pF; ±0.25pF tolerance ranges 1.95–2.45 pF. Tighter tolerance parts are suitable for precision circuits requiring closer capacitance control.

Q: Are all listed parts ROHS3 compliant? A: Yes. All substitute parts listed carry ROHS3 Compliant status, matching the original 08055A2R2CAT2M compliance requirement.
