08055J2R2BAWTR Thin Film Capacitor - Equivalent & Substitute Parts

Part Overview

The 08055J2R2BAWTR is a 2.2 pF thin film capacitor manufactured by KYOCERA AVX in the 0805 (2012 Metric) surface mount package. This component is rated for 50 V operation and features RF characteristics with high Q and low loss performance. The part is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08055J2R2BAWTR is determined by the following critical parameters:

• Capacitance value: 2.2 pF (exact match required)
• Tolerance: ±0.1 pF (exact match required)
• Voltage rating: 50 V (minimum requirement)
• Package: 0805 (2012 Metric) surface mount (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Dielectric type: Thin film (exact match required)
• RF characteristics: High Q, Low Loss (exact match required)

The 08055J2R2BBTTR meets all substitution criteria as a direct functional equivalent from the same manufacturer, differing only in series designation (Accu-P® vs. Accu-F®), packaging format (Tape & Reel vs. standard), and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 08055J2R2BBTTR is the direct functional substitute for the obsolete 08055J2R2BAWTR. Both parts are manufactured by KYOCERA AVX and share identical electrical specifications: 2.2 pF capacitance, ±0.1 pF tolerance, 50 V voltage rating, and 0805 surface mount package with RF performance characteristics.

The primary distinction is product status: the 08055J2R2BBTTR is currently active in production, whereas the 08055J2R2BAWTR is obsolete. The substitute part also provides ROHS3 compliance, whereas the original part is RoHS non-compliant. The seated height difference (0.73 mm vs. 1.13 mm) must be evaluated against specific PCB layout constraints.

For new designs or ongoing procurement, the 08055J2R2BBTTR is the appropriate selection. For legacy systems requiring the exact original part, the 08055J2R2BAWTR remains available in current inventory (766 pcs).

Frequently Asked Questions (FAQ)

Q: Can the 08055J2R2BBTTR be used as a direct replacement for the 08055J2R2BAWTR?

A: Yes. Both parts are electrically and mechanically equivalent with identical capacitance (2.2 pF), tolerance (±0.1 pF), voltage rating (50 V), package (0805), and operating temperature range (-55°C to 125°C). The substitute is actively manufactured and RoHS3 compliant.

Q: What is the difference between the Accu-F® and Accu-P® series?

A: Both series are thin film capacitor lines from KYOCERA AVX with identical electrical performance for this application. The Accu-P® series (08055J2R2BBTTR) is the current active production line, while the Accu-F® series (08055J2R2BAWTR) is obsolete.

Q: Does the height difference (0.73 mm vs. 1.13 mm) affect PCB compatibility?

A: The seated height difference must be evaluated against specific PCB layout and clearance requirements. Both parts use the same 0805 footprint and are surface mount compatible. Height variation may impact applications with strict vertical space constraints.

Q: Is the 08055J2R2BBTTR RoHS compliant?

A: Yes, the 08055J2R2BBTTR is ROHS3 compliant. The original 08055J2R2BAWTR is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulations.

Q: What packaging formats are available for the substitute part?

A: The 08055J2R2BBTTR is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement process.
