Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 08055A3R0DAT2A are classified based on the following substitution criteria:

Upgrade Substitutes maintain identical capacitance (3 pF) and package (0805), with improved tolerance specifications (±0.25pF versus ±0.5pF) or higher voltage ratings (100V versus 50V). These parts are direct functional upgrades with enhanced performance margins.

Direct Equivalents match all critical electrical parameters (3 pF capacitance, ±0.5pF tolerance, 50V rating, C0G/NP0 temperature coefficient) and mechanical specifications (0805 package) from alternative manufacturers. These parts provide equivalent functionality with interchangeable performance.

All substitute parts maintain the same operating temperature range (-55°C ~ 125°C), surface mount configuration, and environmental compliance (ROHS3, MSL 1).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active production components with ROHS3 compliance and MSL 1 rating, meeting the environmental and regulatory requirements of the original 08055A3R0DAT2A.

For direct replacement with identical electrical performance: Select C0805C309D5GAC7800 (KEMET) as a direct equivalent. This part matches the original ±0.5pF tolerance and 50V rating while maintaining the same 0805 package footprint and C0G/NP0 temperature stability.

For improved tolerance specifications: Select 08055A3R0CAT2A (KYOCERA AVX) or CC0805CRNPO9BN3R0 (YAGEO). Both offer ±0.25pF tolerance, providing tighter capacitance control compared to the original ±0.5pF specification while maintaining 50V rating and 0805 package compatibility.

For higher voltage margin applications: Select 08051A3R0CAT2A (KYOCERA AVX), which provides 100V rating with ±0.25pF tolerance. This upgrade is suitable for circuits requiring enhanced voltage headroom while maintaining identical capacitance and package specifications.

Physical height variations exist among substitutes (ranging from 0.024" to 0.037" maximum thickness). Verify PCB layout clearance requirements before final selection, particularly in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can I use CC0805CRNPO9BN3R0 as a direct replacement for 08055A3R0DAT2A?

A: Yes. Both parts share identical capacitance (3 pF), voltage rating (50V), temperature coefficient (C0G/NP0), and 0805 package specification. The CC0805CRNPO9BN3R0 offers improved tolerance (±0.25pF versus ±0.5pF) and reduced thickness (0.024" versus 0.037"), making it a compatible upgrade with better performance margins.

Q: What is the difference between the KYOCERA AVX 08055A3R0DAT2A and 08055A3R0CAT2A?

A: Both parts are manufactured by KYOCERA AVX in the same 0805 package with identical 3 pF capacitance and 50V rating. The primary difference is tolerance: 08055A3R0DAT2A specifies ±0.5pF, while 08055A3R0CAT2A specifies ±0.25pF. The tighter tolerance part (CAT2A) provides improved capacitance stability.

Q: Is the 08051A3R0CAT2A suitable for my 50V circuit?

A: Yes. The 08051A3R0CAT2A is rated for 100V operation, which exceeds the 50V requirement. This part is electrically compatible and provides additional voltage margin. All other specifications (3 pF capacitance, ±0.25pF tolerance, C0G/NP0 coefficient, 0805 package, -55°C to 125°C operating range) match the original design requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (unlimited moisture sensitivity) rating, matching the environmental compliance profile of the original 08055A3R0DAT2A.

Q: Does package thickness affect PCB assembly compatibility?

A: Package thickness variations exist among substitutes (0.024" to 0.037" maximum). Verify that selected substitute parts do not exceed PCB layout clearance specifications, particularly in applications with limited vertical space or components mounted on both sides of the board.
