08051A2R4DAT2A Equivalent & Substitute Parts

Part Overview

The 08051A2R4DAT2A is a 2.4 pF ceramic capacitor manufactured by KYOCERA AVX in 0805 (2012 Metric) surface mount package. This component operates at 100V rated voltage with C0G/NP0 temperature coefficient, suitable for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 08051A2R4DAT2A are qualified based on the following critical parameters:

• Capacitance value: 2.4 pF (exact match required)
• Voltage rating: 100V (minimum requirement)
• Temperature coefficient: C0G/NP0 (mandatory for stability)
• Package: 0805 (2012 Metric) surface mount (physical compatibility)
• Operating temperature range: -55°C ~ 125°C (functional compatibility)
• RoHS and REACH compliance status (regulatory alignment)
• Moisture sensitivity: MSL 1 (handling and storage compatibility)

The identified substitutes meet all these criteria. Tolerance variations (±0.25pF vs ±0.5pF) represent tighter specifications in substitute parts, which are acceptable for applications requiring the original tolerance or better.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified alternatives to the 08051A2R4DAT2A based on electrical and mechanical compatibility:

08051A2R4CAT2A (KYOCERA AVX) maintains manufacturer continuity with identical physical dimensions and improved tolerance specification (±0.25pF). This part is suitable for direct replacement in applications where tighter capacitance tolerance is acceptable or beneficial.

C0805C249C1GAC7800 (KEMET) provides cross-manufacturer substitution with equivalent electrical performance. The slightly reduced thickness (0.035" vs 0.037") and marginally smaller length (2.00mm vs 2.01mm) remain within acceptable mechanical tolerances for 0805 package footprints. This part includes Low ESL feature designation.

All three parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring regulatory and handling compatibility across the product lifecycle.

Frequently Asked Questions (FAQ)

Q: Can 08051A2R4CAT2A replace 08051A2R4DAT2A in existing designs?

A: Yes. Both parts share identical capacitance (2.4 pF), voltage rating (100V), temperature coefficient (C0G/NP0), package (0805), and operating temperature range (-55°C ~ 125°C). The substitute has tighter tolerance (±0.25pF vs ±0.5pF), which is compatible with applications designed for the original part.

Q: What is the difference between the two KYOCERA AVX parts?

A: The primary difference is tolerance specification. 08051A2R4DAT2A carries ±0.5pF tolerance, while 08051A2R4CAT2A carries ±0.25pF tolerance. Both are electrically and mechanically identical otherwise.

Q: Can KEMET C0805C249C1GAC7800 be used as a direct replacement?

A: Yes. The KEMET part meets all critical electrical parameters (2.4 pF, 100V, C0G/NP0, -55°C ~ 125°C) and physical package requirements (0805). Dimensional variations (thickness 0.035" vs 0.037", length 2.00mm vs 2.01mm) are within acceptable tolerances for standard PCB assembly processes.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent regulatory and handling requirements.

Q: What does MSL 1 (Unlimited) mean for storage and handling?

A: MSL 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All three parts share this classification.
