Key Parameters

Substitute Part Grouping Explanation

Substitution of the 08055J2R4BAWTR is determined by strict equivalence across the following critical parameters:

• Capacitance value: 2.4 pF (exact match required)
• Tolerance: ±0.1 pF (exact match required)
• Rated voltage: 50 V (minimum requirement)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C ~ 125°C (minimum requirement)
• RF performance characteristics: High Q, Low Loss (functional requirement)

The 08055J2R4BBTTR meets all substitution criteria as a direct equivalent from the same manufacturer, with identical electrical specifications and package dimensions.

Parameter Comparison

Engineering Selection Recommendations

The 08055J2R4BBTTR is the direct substitute for the obsolete 08055J2R4BAWTR. Both components share identical electrical specifications, capacitance values, tolerance, rated voltage, and RF performance characteristics. The substitute part is currently in active production status, ensuring long-term availability.

The primary differences between the main part and substitute are:

• Product status: The substitute is Active, whereas the main part is Obsolete
• RoHS compliance: The substitute is ROHS3 Compliant, while the main part is RoHS non-compliant
• Physical height: The substitute has a maximum seated height of 0.044" (1.13mm) compared to 0.029" (0.73mm) for the main part
• Packaging: The substitute is supplied in Tape & Reel (TR) format

For new designs or production continuity, the 08055J2R4BBTTR is the appropriate selection. The increased height dimension must be verified against PCB layout constraints and assembly equipment specifications. The improved RoHS compliance status of the substitute aligns with current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 08055J2R4BBTTR be used as a direct replacement for the 08055J2R4BAWTR?

A: Yes. Both components have identical capacitance (2.4 pF), tolerance (±0.1 pF), rated voltage (50 V), package type (0805 / 2012 Metric), and RF performance characteristics (High Q, Low Loss). The electrical performance is equivalent.

Q: What is the significance of the height difference between these parts?

A: The substitute part has a maximum seated height of 0.044" (1.13mm) versus 0.029" (0.73mm) for the original part. This 0.015" (0.40mm) difference must be evaluated against PCB layout clearances, component stacking requirements, and assembly equipment specifications to ensure compatibility.

Q: Why is the main part marked as Obsolete?

A: The 08055J2R4BAWTR (Accu-F® series) has been discontinued by the manufacturer. The 08055J2R4BBTTR (Accu-P® series) represents the current production equivalent with identical electrical specifications.

Q: Are there any compliance differences between these parts?

A: The substitute part is ROHS3 Compliant, while the main part is RoHS non-compliant. Both parts are REACH Unaffected and classified under ECCN EAR99. For applications subject to RoHS regulations, the substitute part is the appropriate selection.

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

A: The 08055J2R4BBTTR is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both the main part and substitute are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
