Key Parameters

Substitute Part Grouping Explanation

Substitution of the 08055U151FAT2A is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 150 pF
• Tolerance: ±1%
• Temperature Coefficient: C0G/NP0
• Package / Case: 0805 (2012 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C

Allowable Variation Parameters:

• Voltage Rating: May be equal to or greater than the original 50V rating

The 08051U151FAT2A qualifies as a direct substitute based on identical capacitance, tolerance, temperature coefficient, package dimensions, and operating temperature range. The voltage rating upgrade from 50V to 100V represents an enhancement that maintains backward compatibility in applications where the original 50V rating was sufficient.

Parameter Comparison

Engineering Selection Recommendations

The 08051U151FAT2A serves as a qualified equivalent substitute for the 08055U151FAT2A. Both parts maintain Active product status and full compliance with RoHS3 and REACH regulations. The substitute part carries identical mechanical and electrical specifications with the exception of voltage rating, which is increased from 50V to 100V. This voltage upgrade does not compromise performance in applications designed for the original 50V rating and provides enhanced margin for transient voltage conditions. Both parts carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage or handling. Selection between these parts should be based on application voltage requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 08051U151FAT2A (100V) replace the 08055U151FAT2A (50V) in my circuit?

A: Yes. The 08051U151FAT2A is a direct substitute with identical capacitance (150 pF), tolerance (±1%), temperature coefficient (C0G/NP0), package (0805), and operating temperature range (-55°C ~ 125°C). The increased voltage rating of 100V is compatible with applications originally specified for 50V.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts share identical package dimensions: 0.079" L x 0.049" W (2.01mm x 1.25mm) with maximum thickness of 0.045" (1.15mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the 08055U151FAT2A and 08051U151FAT2A carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8532.24.0020.

Q: What applications are these capacitors suitable for?

A: Both parts are specified for RF, microwave, and high-frequency applications. The ultra-low ESR characteristic makes them suitable for circuits requiring minimal parasitic resistance and low dissipation factor.
