04025A2R5BAT2A Equivalent & Substitute Parts

Part Overview

The 04025A2R5BAT2A is a 2.5 pF ceramic capacitor manufactured by KYOCERA AVX, designed for general-purpose applications requiring stable capacitance across temperature variations. This surface-mount multilayer ceramic capacitor (MLCC) features C0G/NP0 temperature coefficient characteristics and is rated for 50V operation. The part is currently in active production status with 700 units available in inventory.

Equivalent and substitute parts become necessary when the primary manufacturer experiences supply constraints, lead time extensions, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 04025A2R5BAT2A is determined by strict equivalence across the following parameters:

• Capacitance value: 2.5 pF (exact match required)
• Tolerance: ±0.1pF (exact match required)
• Voltage rating: 50V (minimum requirement; higher ratings acceptable)
• Temperature coefficient: C0G/NP0 (required for temperature stability)
• Operating temperature range: -55°C ~ 125°C (minimum requirement)
• Package: 0402 (1005 Metric) (exact match required for PCB compatibility)
• Mounting type: Surface Mount, MLCC (exact match required)
• Physical dimensions: 0.039" L x 0.020" W, 0.022" max thickness (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (required for regulatory alignment)

All substitute parts listed meet these criteria and are electrically and mechanically interchangeable with the primary part.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (04025A2R5BAT2A - KYOCERA AVX): Active product status with current inventory availability. Suitable for new designs and production applications requiring long-term supply continuity.

Direct Equivalent (GRM1555C1H2R5BA01D - Murata Electronics): Meets all electrical and mechanical parameters. Product status is "Not For New Designs," indicating this part is in mature phase with potential future discontinuation. Suitable for legacy system maintenance or when supply from primary manufacturer is constrained. Inventory availability is significantly higher (40,997 units).

Parametric Equivalent (CBR04C259B5GAC - KEMET): Active product status with specialized RF/microwave application features (High Q, Low Loss, Ultra Low ESR). Electrical and mechanical parameters are fully compatible. Recommended for applications requiring enhanced performance in RF and high-frequency circuits. Inventory: 2,975 units.

Parametric Equivalent (CC0402BRNPO9BN2R5 - YAGEO): Active product status with general-purpose application profile. All electrical and mechanical parameters match the primary part. Highest inventory availability (81,679 units). Suitable for general-purpose applications and high-volume production scenarios.

All substitute parts carry ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment with the primary part.

Frequently Asked Questions (FAQ)

Q: Can I substitute GRM1555C1H2R5BA01D for 04025A2R5BAT2A in new designs?

A: GRM1555C1H2R5BA01D is electrically and mechanically equivalent and carries "Not For New Designs" status from Murata. While substitution is technically feasible, KYOCERA AVX 04025A2R5BAT2A or alternative active-status parts (CBR04C259B5GAC or CC0402BRNPO9BN2R5) are preferred for new design implementations to ensure long-term supply continuity.

Q: What is the difference between CBR04C259B5GAC and the other substitutes?

A: CBR04C259B5GAC is optimized for RF and microwave applications with specified High Q, Low Loss, and Ultra Low ESR characteristics. All other substitutes are general-purpose parts. Electrical and mechanical parameters are identical, but CBR04C259B5GAC is recommended when circuit performance in high-frequency applications is critical.

Q: Are all substitute parts pin-compatible with the primary part?

A: Yes. All substitute parts use identical 0402 (1005 Metric) surface-mount package with matching physical dimensions (0.039" L x 0.020" W, 0.022" max thickness). PCB footprints and reflow soldering profiles are directly compatible.

Q: Do all parts meet the same compliance requirements?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the primary part 04025A2R5BAT2A.

Q: Which substitute offers the best inventory availability?

A: CC0402BRNPO9BN2R5 (YAGEO) offers the highest inventory level at 81,679 units, followed by GRM1555C1H2R5BA01D (Murata) at 40,997 units. Both are suitable for high-volume production requirements.

Q: Can I use these substitutes interchangeably in the same circuit?

A: Yes, for general-purpose applications. All parts meet identical electrical specifications (2.5 pF ±0.1pF, 50V, C0G/NP0, -55°C ~ 125°C). For RF/microwave circuits, CBR04C259B5GAC is preferred due to its optimized performance characteristics.
