Substitute Part Grouping Explanation

Substitution for the EEE-1HA2R2SR is determined by strict equivalence across the following critical parameters: capacitance (2.2 µF), voltage rating (50 V), tolerance (±20%), package type (Radial, Can - SMD), physical dimensions (0.157" diameter, maximum height compatibility), surface mount land size (0.169" L x 0.169" W), and mounting type (Surface Mount). Additional considerations include operating temperature range, lifetime rating at specified temperature, polarization (Polar), and compliance certifications (RoHS, REACH, AEC-Q200 where applicable).

Substitute parts are categorized as follows:

Direct Equivalents: Parts with identical electrical specifications and physical dimensions, differing only in packaging format or minor manufacturing variations.

Upgrade Substitutes: Parts with enhanced performance characteristics (higher temperature ratings, extended lifetime) while maintaining full backward compatibility with the original part's electrical and mechanical specifications.

Parametric Equivalents: Parts from the same manufacturer series with identical core electrical parameters but different packaging or product status.

Cross-Manufacturer Equivalents: Parts from alternative manufacturers meeting the same electrical and mechanical specifications.

Engineering Selection Recommendations

For Active Production (Recommended Primary Choices):

EEE-HB1H2R2R and EEE-HB1H2R2AR from Panasonic are active products offering improved operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C) and extended lifetime at elevated temperature (2000 Hrs @ 105°C). Both maintain identical electrical specifications and are RoHS3 compliant with AEC-Q200 automotive ratings. Height difference (0.228" versus 0.213") requires PCB layout verification.

EDK225M050A9BAAK from KEMET is an active product with identical electrical and physical specifications to the original part. RoHS3 compliant with matching 2000 Hrs @ 85°C lifetime rating. Suitable for direct substitution in existing designs.

EMVL500ARA2R2MD60G from Chemi-Con is active with enhanced lifetime (3000 Hrs @ 105°C) and extended operating temperature range. Height of 0.236" requires PCB clearance verification.

For Obsolete or Legacy Designs:

50SEV2.2M4X5.5 (Rubycon, Obsolete), AVE225M50B12T-F (CDE, Obsolete), and AVS225M50B12T-F (CDE, Not For New Designs) are available in limited inventory but carry obsolete or legacy status. Use only for maintenance of existing products or when active alternatives are unavailable.

EMVA630ARA2R2MD55G (Chemi-Con, Last Time Buy) carries a higher voltage rating (63 V) and is suitable only where voltage derating is acceptable. Height of 0.205" provides improved PCB space efficiency.

Frequently Asked Questions (FAQ)

Q: Can EEE-HD1H2R2R replace EEE-1HA2R2SR directly on the PCB?

A: Electrical substitution is valid. Physical compatibility requires verification. EEE-HD1H2R2R has a maximum height of 0.240" compared to 0.213" for the original part. Confirm PCB clearance and reflow profile compatibility for the higher temperature rating (105°C operating temperature).

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

A: Both are identical in electrical specifications, physical dimensions, and performance ratings. The difference is in packaging format: EEE-HB1H2R2AR uses standard Cut Tape (CT) & Digi-Reel® packaging, while EEE-HB1H2R2R uses the same packaging. Consult your procurement requirements for packaging preference.

Q: Is EDK225M050A9BAAK suitable for automotive applications?

A: EDK225M050A9BAAK meets the electrical and physical specifications for 50 V, 2.2 µF applications. However, it does not carry AEC-Q200 automotive certification. Use only in non-automotive applications or where automotive certification is not required.

Q: Why does EMVA630ARA2R2MD55G have a different voltage rating?

A: EMVA630ARA2R2MD55G is rated at 63 V instead of 50 V. This part is suitable only where the higher voltage rating provides design margin or where voltage derating is acceptable. It is not a direct replacement for 50 V-rated designs.

Q: Can I use parts with different heights interchangeably?

A: Height differences require PCB layout verification. Parts with heights exceeding the original specification may violate clearance requirements for adjacent components or enclosure constraints. Confirm mechanical compatibility before substitution.

Q: What does "Not For New Designs" status mean?

A: Parts with this status are available from existing inventory but are not recommended for new product designs. Panasonic recommends using active alternatives such as EEE-HB1H2R2R or EEE-HD1H2R2R for new designs.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are RoHS3 compliant or RoHS compliant. Verify specific RoHS certification requirements for your application and supply chain documentation.
