EEE-HD1H2R2R Equivalent & Substitute Parts

Part Overview

The EEE-HD1H2R2R is a 2.2 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package, manufactured by Panasonic Electronic Components. This component is rated for automotive applications and high-temperature reflow processes, with a 5000-hour lifetime at 105°C. The part is currently in active production status.

Substitute parts become necessary when the primary part reaches end-of-life, experiences supply constraints, or when design requirements permit relaxation of specific performance parameters such as lifetime rating or ripple current handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-HD1H2R2R is determined by the following mandatory parameters:

• Capacitance Value: Must be 2.2 µF
• Voltage Rating: Must be 50 V or higher
• Tolerance: Must be ±20% or tighter
• Package Type: Must be Radial, Can - SMD
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must support -40°C ~ 105°C minimum
• Polarization: Must be Polar
• AEC-Q200 Compliance: Required for automotive applications
• RoHS Compliance: Must meet RoHS requirements

The EEE-FC1H2R2R meets all mandatory substitution criteria. However, it differs in lifetime rating (1000 Hrs @ 105°C versus 5000 Hrs), ripple current specifications, impedance, physical height, and product status (Not For New Designs). These differences must be evaluated against specific application requirements.

Engineering Selection Recommendations

The EEE-HD1H2R2R is the preferred choice for new designs due to its active product status and extended 5000-hour lifetime rating at 105°C. This part is suitable for automotive applications requiring long-term reliability and high-temperature performance.

The EEE-FC1H2R2R is classified as "Not For New Designs" and should be considered only for legacy system maintenance, repair, or retrofit applications where the reduced 1000-hour lifetime at 105°C is acceptable. This part maintains AEC-Q200 compliance and RoHS compliance, ensuring compatibility with automotive standards. The lower impedance (5 Ohms versus 12 Ohms) and higher ripple current ratings of the EEE-FC1H2R2R may provide advantages in specific high-ripple-current applications, but the reduced lifetime rating represents a significant trade-off.

Both parts share identical capacitance, voltage rating, tolerance, operating temperature range, and mounting footprint, enabling direct PCB-level substitution. The 0.7mm height difference (6.10mm versus 5.40mm) must be evaluated against mechanical clearance constraints in the application.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FC1H2R2R be used as a direct replacement for the EEE-HD1H2R2R in new designs?

A: No. The EEE-FC1H2R2R carries a "Not For New Designs" status. While it meets the same electrical specifications and AEC-Q200 automotive rating, its 1000-hour lifetime at 105°C is significantly lower than the EEE-HD1H2R2R's 5000-hour rating. New designs should use the EEE-HD1H2R2R.

Q: Are there physical compatibility issues between these parts?

A: Both parts use identical surface mount land sizes (0.169" L x 0.169" W / 4.30mm x 4.30mm) and the same 0.157" diameter (4.00mm). The EEE-FC1H2R2R is 0.7mm shorter (5.40mm versus 6.10mm), which may provide a clearance advantage in space-constrained designs but does not prevent substitution from a PCB layout perspective.

Q: What is the impact of the impedance difference between these parts?

A: The EEE-FC1H2R2R has lower impedance (5 Ohms versus 12 Ohms), which results in better high-frequency ripple current performance. However, this does not affect the fundamental capacitance or voltage rating. The impedance difference is relevant only in applications with specific ripple current or noise filtering requirements.

Q: Are both parts compliant with automotive standards?

A: Yes. Both the EEE-HD1H2R2R and EEE-FC1H2R2R carry AEC-Q200 ratings and are suitable for automotive applications. The EEE-HD1H2R2R is ROHS3 compliant, while the EEE-FC1H2R2R is RoHS compliant. Both meet REACH requirements.

Q: What packaging formats are available for these parts?

A: The EEE-HD1H2R2R is supplied in Cut Tape (CT) and Digi-Reel packaging. The EEE-FC1H2R2R is supplied in Tape & Reel (TR) format. Packaging selection should align with production volume and assembly process requirements.
