Engineering Selection Recommendations

Panasonic HA/HB/HC/HD Series (Recommended for Automotive Applications):

The EEE-HB1H2R2AR and EEE-HB1H2R2R are direct upgrades from the EEE-HA1H2R2AR, offering doubled lifetime (2000 hours at 105°C) while maintaining identical electrical specifications and AEC-Q200 automotive qualification. These parts carry Active product status and are suitable for new designs. Height increase from 0.213" to 0.228" requires PCB layout verification but remains within typical board clearance tolerances.

The EEE-HC1H2R2R provides 3000-hour lifetime with Active status and ROHS3 compliance. The EEE-HD1H2R2R offers the highest reliability with 5000-hour lifetime, Active status, and AEC-Q200 qualification, making it optimal for long-lifecycle automotive applications. Both HC and HD series increase height to 0.240", requiring board clearance confirmation.

The EEE-FC1H2R2R and EEE-HA1H2R2R are parametric equivalents with identical 1000-hour lifetime but carry Not For New Designs status, limiting their suitability for new applications despite matching electrical and mechanical specifications.

Cross-Manufacturer Equivalents:

TYEH1H225D55MTR (TE Connectivity) is an Active product with identical electrical specifications and minimal height variation (0.209"). It provides equivalent performance for general-purpose applications but lacks AEC-Q200 automotive qualification.

UUL1H2R2MCL1GS (Nichicon) offers 5000-hour lifetime with Active status and ROHS3 compliance, suitable for extended-life applications. Height of 0.240" requires clearance verification.

UZG1H2R2MCL1GB (Nichicon) is an Active product with 1000-hour lifetime and the lowest profile (0.156"), beneficial for space-constrained designs. Verify compatibility with application requirements.

EMVE500ARA2R2MD55G (Chemi-Con) carries Obsolete status and should be avoided for new designs despite matching electrical specifications.

Selection Criteria:

For new automotive designs, prioritize Panasonic HB, HC, or HD series due to AEC-Q200 qualification and Active product status. For general-purpose applications, TE Connectivity TYEH1H225D55MTR or Nichicon UUL1H2R2MCL1GS provide equivalent performance. Verify PCB layout clearance for parts with increased height. Confirm RoHS compliance requirements with procurement specifications.

Frequently Asked Questions (FAQ)

Q: Can I use EEE-HB1H2R2AR as a direct replacement for EEE-HA1H2R2AR?

A: Yes. Both parts share identical capacitance (2.2 µF), voltage rating (50 V), tolerance (±20%), and surface mount land size (0.169" x 0.169"). The EEE-HB1H2R2AR has increased height (0.228" vs 0.213") and doubled lifetime (2000 vs 1000 hours). Verify PCB clearance for the additional 0.015" height. The HB series carries Active product status, making it preferable for new designs.

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-hour lifetime. The primary difference is packaging: EEE-HB1H2R2AR uses Tape & Reel (TR) packaging, while EEE-HB1H2R2R uses Cut Tape (CT) & Digi-Reel. Select based on procurement and assembly requirements.

Q: Why does the EEE-HA1H2R2AR have "Not For New Designs" status?

A: Panasonic designates this part as Not For New Designs to encourage migration to improved product lines with extended lifetimes and enhanced reliability. The EEE-HB, HC, and HD series offer superior performance characteristics while maintaining compatibility with existing designs.

Q: Can I use Nichicon UUL1H2R2MCL1GS in an automotive application?

A: UUL1H2R2MCL1GS meets the electrical and mechanical requirements (2.2 µF, 50 V, ±20%, surface mount) and carries ROHS3 compliance. However, it lacks AEC-Q200 automotive qualification. Use only if your application does not mandate automotive-grade certification. Verify with your quality and procurement departments.

Q: What is the impact of height variation among substitute parts?

A: Height variations range from 0.156" (UZG1H2R2MCL1GB) to 0.240" (EEE-HC1H2R2R and EEE-HD1H2R2R). The original EEE-HA1H2R2AR is 0.213". Verify PCB layout clearance, component spacing, and board assembly constraints before selecting parts with increased height. Shorter parts may offer space advantages but must meet electrical performance requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry either RoHS Compliant or ROHS3 Compliant status, meeting environmental and regulatory requirements.

Q: Which substitute offers the best reliability for long-lifecycle applications?

A: EEE-HD1H2R2R (Panasonic) and UUL1H2R2MCL1GS (Nichicon) both provide 5000-hour lifetime at 105°C. The EEE-HD1H2R2R is preferred for automotive applications due to AEC-Q200 qualification and Active product status.
