08055J0R8BAWTR Equivalent & Substitute Parts

Part Overview

The 08055J0R8BAWTR is a 0.8 pF thin film capacitor manufactured by KYOCERA AVX in the Accu-F® series, rated for 50 V operation in a 0805 (2012 Metric) surface mount package. This component is designed for RF applications requiring high Q and low loss characteristics. The part is currently listed as obsolete, making identification of compatible substitute components essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the 08055J0R8BAWTR is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.8 pF (exact match required)
• Tolerance: ±0.1 pF (exact match required)
• Voltage rating: 50 V (minimum acceptable)
• Package / Case: 0805 (2012 Metric) (exact match required for PCB compatibility)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Features: RF, High Q, Low Loss (functional requirement match)

The 08055J0R8BBTTR from KYOCERA AVX meets all substitution criteria. Both parts are manufactured by the same supplier, share identical electrical specifications, and are housed in the same physical package. The primary distinction is product status: the substitute part is active and currently available, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The 08055J0R8BBTTR is the direct functional equivalent for the obsolete 08055J0R8BAWTR. Both components deliver identical electrical performance across all specified parameters: capacitance, tolerance, voltage rating, temperature range, and RF characteristics.

The substitute part offers two additional advantages: it maintains active product status with current manufacturing availability, and it achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This compliance improvement supports modern supply chain requirements and environmental regulations.

A single design consideration exists: the substitute part has a maximum seated height of 0.044" (1.13 mm) compared to 0.029" (0.73 mm) for the original part. This 0.015" (0.40 mm) height difference must be evaluated against PCB layout constraints and clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 08055J0R8BBTTR be used as a direct replacement for the 08055J0R8BAWTR?

A: Yes. Both parts share identical electrical specifications (0.8 pF capacitance, ±0.1 pF tolerance, 50 V rating) and are housed in the same 0805 (2012 Metric) surface mount package. The substitute part is electrically and mechanically compatible for PCB assembly.

Q: What is the primary reason to switch from the 08055J0R8BAWTR to the 08055J0R8BBTTR?

A: The original part is obsolete and no longer manufactured. The substitute part is active and currently available from KYOCERA AVX, ensuring reliable procurement for new production and field service applications.

Q: Are there any compliance differences between these parts?

A: Yes. The 08055J0R8BBTTR is ROHS3 compliant, while the 08055J0R8BAWTR is RoHS non-compliant. This compliance improvement may be required for applications subject to environmental regulations or customer specifications.

Q: Does the height difference between these parts affect PCB design?

A: The substitute part is 0.015" (0.40 mm) taller when seated. PCB layouts with tight vertical clearance constraints must be evaluated to confirm adequate space. In most standard RF applications, this height difference does not present a design obstacle.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 08055J0R8BAWTR and 08055J0R8BBTTR are manufactured by KYOCERA AVX. The parts belong to different product series (Accu-F® and Accu-P® respectively) but maintain equivalent electrical and mechanical specifications.

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

A: The 08055J0R8BBTTR is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
