08055A2R4DAT2A Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 08055A2R4DAT2A is a 2.4 pF ceramic capacitor manufactured by KYOCERA AVX in 0805 (2012 Metric) surface mount package. This C0G/NP0 temperature coefficient capacitor operates at 50V rated voltage with ±0.5pF tolerance across the -55°C to 125°C temperature range. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support design flexibility, inventory optimization, and supply chain continuity for applications requiring 2.4 pF capacitance in 0805 form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08055A2R4DAT2A is determined by the following critical parameters: capacitance value (2.4 pF), temperature coefficient (C0G/NP0), package form factor (0805), and mounting type (surface mount MLCC). Voltage rating and tolerance are secondary parameters that define upgrade or downgrade relationships.

Direct equivalents maintain identical capacitance, tolerance, voltage rating, and temperature coefficient. Upgrade substitutes increase voltage rating or improve tolerance while maintaining the same capacitance and temperature coefficient. All substitute parts must conform to 0805 package dimensions and surface mount assembly requirements.

The following substitute parts meet these criteria:

• 08051A2R4CAT2A (KYOCERA AVX): Upgrade with 100V rating and ±0.25pF tolerance
• C0805C249D5GAC7800 (KEMET): Direct equivalent with 50V rating and ±0.5pF tolerance
• C0805C249C1GAC7800 (KEMET): Upgrade with 100V rating and ±0.25pF tolerance
• CC0805CRNPO9BN2R4 (YAGEO): Upgrade with 50V rating and ±0.25pF tolerance

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. Selection between direct equivalents and upgrade substitutes depends on circuit voltage margin requirements and tolerance specifications.

For applications operating at or near 50V, the direct equivalent C0805C249D5GAC7800 (KEMET) provides identical electrical performance with alternative sourcing. The KYOCERA AVX 08051A2R4CAT2A and KEMET C0805C249C1GAC7800 offer increased voltage headroom at 100V with improved ±0.25pF tolerance, suitable for designs requiring enhanced safety margins or tighter capacitance control. The YAGEO CC0805CRNPO9BN2R4 provides improved tolerance at the original 50V rating.

All parts share identical package dimensions (0805), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and MSL 1 rating, ensuring direct PCB assembly compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can I use a 100V rated substitute in place of the 50V original part?

A: Yes. The 08051A2R4CAT2A and C0805C249C1GAC7800 are rated for 100V and are electrically compatible with circuits designed for 50V operation. Higher voltage rating provides additional safety margin without affecting circuit performance.

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents (C0805C249D5GAC7800) match the original 50V rating and ±0.5pF tolerance. Upgrade substitutes increase voltage rating to 100V or improve tolerance to ±0.25pF, providing enhanced performance characteristics while maintaining the same 2.4 pF capacitance.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All listed substitutes are supplied in Tape & Reel (TR) packaging and conform to 0805 (2012 Metric) surface mount package specifications, ensuring compatibility with standard PCB assembly processes.

Q: Do substitute parts require any PCB layout modifications?

A: No. All substitute parts maintain identical 0805 package dimensions and surface mount footprint. Direct PCB assembly compatibility is maintained without design changes.

Q: Which substitute offers the best tolerance performance?

A: The 08051A2R4CAT2A, C0805C249C1GAC7800, and CC0805CRNPO9BN2R4 all provide ±0.25pF tolerance, compared to ±0.5pF for the original part and C0805C249D5GAC7800 direct equivalent.
