EEE-HD1H3R3R Equivalent & Substitute Parts

Part Overview

The EEE-HD1H3R3R is a 3.3 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This component is rated for automotive and high-temperature reflow applications with a 5000-hour lifetime at 105°C and AEC-Q200 compliance. 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 relaxed performance specifications such as reduced lifetime ratings or lower ripple current handling.

Substitute Part Grouping Explanation

Substitution of the EEE-HD1H3R3R is permissible with the EEE-FC1H3R3R based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters (Substitution Basis):

• Capacitance: 3.3 µF (identical)
• Voltage Rating: 50 V (identical)
• Tolerance: ±20% (identical)
• Polarization: Polar (identical)
• Operating Temperature Range: -40°C ~ 105°C (identical)
• Package / Case: Radial, Can - SMD (identical)
• Mounting Type: Surface Mount (identical)
• Physical Dimensions: 0.157" Dia (4.00mm) (identical)
• Surface Mount Land Size: 0.169" L x 0.169" W (4.30mm x 4.30mm) (identical)
• AEC-Q200 Compliance: Both parts rated (identical)
• RoHS Compliance: Both parts compliant (identical)
• MSL Rating: 1 (Unlimited) (identical)

Differing Parameters (Design Consideration):

• Lifetime @ 105°C: EEE-HD1H3R3R rated 5000 hours; EEE-FC1H3R3R rated 1000 hours
• Height - Seated (Max): EEE-HD1H3R3R is 0.240" (6.10mm); EEE-FC1H3R3R is 0.213" (5.40mm)
• Ripple Current @ Low Frequency: EEE-HD1H3R3R is 16 mA @ 120 Hz; EEE-FC1H3R3R is 22.5 mA @ 120 Hz
• Ripple Current @ High Frequency: EEE-HD1H3R3R is 27.2 mA @ 10 kHz; EEE-FC1H3R3R is 30 mA @ 100 kHz
• Impedance: EEE-HD1H3R3R is 12 Ohms; EEE-FC1H3R3R is 5 Ohms
• Product Status: EEE-HD1H3R3R is Active; EEE-FC1H3R3R is Not For New Designs

Parameter Comparison

Engineering Selection Recommendations

The EEE-HD1H3R3R remains the preferred choice for new designs due to its active production status and extended 5000-hour lifetime rating at 105°C. This part meets automotive-grade AEC-Q200 compliance and ROHS3 requirements.

The EEE-FC1H3R3R is electrically and mechanically compatible as a substitute where design specifications permit a reduced lifetime rating of 1000 hours at 105°C. The EEE-FC1H3R3R carries a "Not For New Designs" status, making it suitable only for legacy system maintenance, repair, or applications where the lower lifetime specification is acceptable. Both parts maintain identical capacitance, voltage rating, tolerance, operating temperature range, and package footprint.

Selection between these parts depends on application lifetime requirements and supply availability. The EEE-FC1H3R3R offers a lower impedance profile (5 Ohms versus 12 Ohms) and slightly reduced physical height (5.40mm versus 6.10mm), which may provide secondary benefits in specific circuit topologies or space-constrained layouts.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FC1H3R3R be used as a direct replacement for the EEE-HD1H3R3R in automotive applications?

A: The EEE-FC1H3R3R is electrically and mechanically compatible for automotive applications, as both parts carry AEC-Q200 certification. However, the EEE-FC1H3R3R has a reduced lifetime rating of 1000 hours at 105°C compared to the EEE-HD1H3R3R's 5000-hour rating. Substitution is permissible only if the application's thermal stress profile and expected service life are compatible with the lower lifetime specification.

Q: Are the physical dimensions identical between these two parts?

A: The diameter and surface mount land size are identical (0.157" Dia / 4.00mm and 0.169" L x 0.169" W / 4.30mm x 4.30mm). The seated height differs slightly: EEE-HD1H3R3R is 0.240" (6.10mm) maximum, while EEE-FC1H3R3R is 0.213" (5.40mm) maximum. Both parts use the same PCB footprint and are interchangeable from a mounting perspective.

Q: What is the significance of the "Not For New Designs" status on the EEE-FC1H3R3R?

A: This designation indicates that Panasonic has discontinued active development and promotion of the EEE-FC1H3R3R series for new product designs. The part remains available for existing applications and legacy system support. New designs should prioritize the EEE-HD1H3R3R to ensure long-term supply continuity and access to the latest manufacturing improvements.

Q: How do the ripple current ratings differ between these parts?

A: The EEE-HD1H3R3R is rated for 16 mA at 120 Hz and 27.2 mA at 10 kHz. The EEE-FC1H3R3R is rated for 22.5 mA at 120 Hz and 30 mA at 100 kHz. The EEE-FC1H3R3R exhibits higher ripple current capacity at low frequencies and comparable performance at high frequencies, reflecting its lower impedance design (5 Ohms versus 12 Ohms).

Q: Are both parts RoHS compliant?

A: Yes. The EEE-HD1H3R3R is ROHS3 compliant, and the EEE-FC1H3R3R is RoHS compliant. Both parts meet environmental compliance requirements for restricted substance use.
