Substitute Part Grouping Explanation

Substitution of the EEE-1HA2R2AR is determined by strict equivalence in the following parameters: capacitance (2.2 µF), voltage rating (50 V), tolerance (±20%), package type (Radial, Can - SMD), case diameter (4.00 mm), land size (4.30 mm x 4.30 mm), and mounting type (Surface Mount). Parts are grouped into three categories based on substitution relationship:

Direct Manufacturer Substitutes maintain identical electrical and mechanical specifications with different packaging or series variants from the same manufacturer.

Upgrade Substitutes provide enhanced performance characteristics such as extended operating temperature range (-40°C to 105°C) or improved lifetime ratings (2000 Hrs @ 105°C) while maintaining core electrical parameters and mechanical compatibility.

Parametric Equivalents from alternative manufacturers meet all critical electrical and mechanical requirements but may differ in ripple current ratings, ESR values, or application focus.

Engineering Selection Recommendations

For new designs, select from active product status parts: EEE-HD1H2R2R, EEE-HB1H2R2AR, EEE-HB1H2R2R, or EDK225M050A9BAAK. These parts carry current manufacturer support and ROHS3 compliance.

The EEE-HD1H2R2R offers the highest performance specification with 5000 hours lifetime at 105°C and extended operating temperature to 105°C, suitable for high-temperature automotive applications. The EEE-HB series (EEE-HB1H2R2AR and EEE-HB1H2R2R) provides intermediate performance with 2000 hours at 105°C and extended temperature range while maintaining lower profile heights (5.80 mm) compared to the EEE-HD variant (6.10 mm).

The EDK225M050A9BAAK from KEMET is an active alternative from a different manufacturer with identical core specifications and ROHS3 compliance, suitable for applications where multi-source qualification is required.

Parts with Not For New Designs or Obsolete status (EEE-1HA2R2AR, EEE-1HA2R2SR, 50SEV2.2M4X5.5, AVE225M50B12T-F, AVS225M50B12T-F, UWJ1H2R2MCL1GB) are suitable only for legacy system maintenance and repair.

Frequently Asked Questions (FAQ)

Q: Can EEE-HD1H2R2R directly replace EEE-1HA2R2AR in existing designs?

A: Electrical substitution is direct. The EEE-HD1H2R2R maintains identical capacitance, voltage, tolerance, and land size. Physical height increases from 5.40 mm to 6.10 mm; verify PCB clearance before implementation.

Q: What is the difference between EEE-HB1H2R2AR and EEE-HB1H2R2R?

A: Both parts are electrically and mechanically identical with 2.2 µF capacitance, 50 V rating, and 2000 hours lifetime at 105°C. Packaging differs: EEE-HB1H2R2AR uses Cut Tape & Digi-Reel, while EEE-HB1H2R2R uses the same packaging. Selection depends on supply chain and procurement requirements.

Q: Is EDK225M050A9BAAK suitable for automotive applications?

A: EDK225M050A9BAAK meets core electrical and mechanical specifications for 2.2 µF 50 V surface mount applications. However, it does not carry AEC-Q200 certification. Panasonic parts (EEE-HD1H2R2R, EEE-HB series) are recommended for automotive designs requiring AEC-Q200 qualification.

Q: Why does EMVA630ARA2R2MD55G appear in the substitute list but not in the comparison table?

A: EMVA630ARA2R2MD55G has a 63 V voltage rating, which exceeds the 50 V specification of EEE-1HA2R2AR. While it maintains 2.2 µF capacitance and compatible package dimensions, the higher voltage rating places it outside strict electrical equivalence and is not included in direct substitution recommendations.

Q: What is the impact of ripple current differences between substitute parts?

A: Ripple current ratings vary across manufacturers. EEE-1HA2R2AR specifies 27.2 mA @ 10 kHz. Alternatives such as EDK225M050A9BAAK (20 mA @ 10 kHz) and UWJ1H2R2MCL1GB (19.5 mA @ 10 kHz) have lower ratings. Verify ripple current requirements in the target application before substitution.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts carry either RoHS or ROHS3 compliance status. The original EEE-1HA2R2AR is RoHS Compliant; upgrade alternatives are ROHS3 Compliant, which represents a more stringent standard.
