Panasonic EEE-1HA0R1SR Equivalent & Substitute Parts

Part Overview

The Panasonic EEE-1HA0R1SR is a 0.1 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package, rated for 2000 hours at 85°C with AEC-Q200 automotive qualification. This part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain electrical performance across the specified operating temperature range (-40°C to 85°C) and mechanical compatibility with existing PCB designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-1HA0R1SR is determined by the following critical parameters:

• Electrical Equivalence: Capacitance (0.1 µF), voltage rating (50 V), and tolerance (±20%) must be identical
• Thermal Performance: Lifetime rating at 85°C must meet or exceed 2000 hours
• Mechanical Compatibility: Package dimensions and surface mount land size (0.169" L x 0.169" W) must accommodate existing PCB layouts
• Environmental Compliance: RoHS3 compliance and REACH unaffected status required
• Automotive Qualification: AEC-Q200 rating preferred for automotive applications

Two Nichicon alternatives meet these substitution criteria: UZR1H0R1MCL1GB and UZS1H0R1MCL1GB. Both share identical capacitance, voltage, tolerance, operating temperature range, and mounting specifications. The primary distinction lies in thermal lifetime rating and product status.

Parameter Comparison

Engineering Selection Recommendations

Nichicon UZS1H0R1MCL1GB is the primary substitute for the Panasonic EEE-1HA0R1SR. This part maintains identical thermal lifetime (2000 hours at 85°C), matching the original specification exactly. Both parts are classified as obsolete, indicating limited future availability. The UZS1H0R1MCL1GB offers the lowest seated height (4.60mm) among available alternatives, providing superior PCB layout flexibility while maintaining full electrical and mechanical compatibility.

Nichicon UZR1H0R1MCL1GB serves as a secondary alternative. While it meets all electrical and mechanical requirements, its thermal lifetime rating of 1000 hours at 85°C is reduced compared to the original 2000-hour specification. This part is classified as "Not For New Designs," indicating manufacturer discontinuation intent. The UZR1H0R1MCL1GB features the lowest seated height (3.95mm) of all options, suitable for space-constrained applications where thermal lifetime reduction is acceptable.

Both Nichicon substitutes maintain AEC-Q200 automotive qualification status (UZR1H0R1MCL1GB) or general-purpose classification (UZS1H0R1MCL1GB), RoHS3 compliance, and REACH unaffected status, ensuring regulatory compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can UZR1H0R1MCL1GB be used as a direct replacement for EEE-1HA0R1SR?

A: UZR1H0R1MCL1GB is electrically and mechanically compatible with identical capacitance, voltage, tolerance, and operating temperature specifications. However, its thermal lifetime is rated at 1000 hours at 85°C versus the original 2000-hour specification. Selection depends on application thermal stress requirements.

Q: What is the primary difference between the two Nichicon substitutes?

A: Both UZR1H0R1MCL1GB and UZS1H0R1MCL1GB share identical electrical specifications. The key distinction is thermal lifetime: UZR1H0R1MCL1GB is rated for 1000 hours at 85°C, while UZS1H0R1MCL1GB matches the original 2000-hour rating. Physical height also differs: UZR1H0R1MCL1GB (3.95mm) is shorter than UZS1H0R1MCL1GB (4.60mm).

Q: Are the substitute parts compatible with existing PCB designs?

A: Yes. All substitute parts maintain identical surface mount land size (0.169" L x 0.169" W / 4.30mm x 4.30mm) and diameter (0.157" / 4.00mm). Height variations (3.95mm to 5.40mm) are within typical PCB clearance tolerances for surface mount components.

Q: Do the substitutes maintain automotive qualification?

A: UZR1H0R1MCL1GB retains AEC-Q200 automotive qualification. UZS1H0R1MCL1GB is classified for general-purpose applications without specific automotive rating designation.

Q: What is the ripple current difference between the original and substitutes?

A: The original EEE-1HA0R1SR is rated for 1.7 mA at 10 kHz. Both Nichicon substitutes are rated for 1.5 mA at 10 kHz. Both maintain 1 mA at 120 Hz. This reduction in high-frequency ripple current capacity should be evaluated against application requirements.
