Equivalent & Substitute Parts for EEU-EE2G101

Part Overview

The Panasonic EEU-EE2G101 is a 100 µF, 400 V aluminum electrolytic capacitor in radial, can package configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement. The part operates across a temperature range of -25°C to 105°C with a rated lifetime of 10,000 hours at 105°C, serving general-purpose applications requiring stable capacitance and ripple current handling.

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-EE2G101 is determined by strict equivalence across the following parameters: capacitance value (100 µF), voltage rating (400 V), tolerance (±20%), operating temperature range (-25°C to 105°C), polarization (polar), mounting type (through hole), and package configuration (radial, can). All identified substitutes maintain these core electrical and mechanical specifications. Physical dimensions and lifetime ratings may vary within acceptable tolerances for through-hole radial capacitors, provided lead spacing and mounting footprint remain compatible at 0.295" (7.50mm) spacing.

Engineering Selection Recommendations

All three substitute parts maintain full electrical equivalence to the EEU-EE2G101 across capacitance, voltage rating, tolerance, temperature range, and polarization. All substitutes carry active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The UPT2G101MHD6 presents the closest physical match to the original part, with identical diameter (0.709" / 18.00mm) and lead spacing (0.295" / 7.50mm), minimizing PCB layout modifications. This variant supports 5000-hour lifetime at 105°C.

The UPT2G101MHD offers similar electrical performance with 5000-hour lifetime but features a smaller diameter (0.630" / 16.00mm), requiring verification of available board space.

The LDQ2G101MERYGA provides an alternative from Nichicon's LDQ series with identical lead spacing but increased physical height (0.787" / 20.00mm). This part carries a reduced lifetime rating of 2000 hours at 105°C, suitable only for applications where extended thermal endurance is not critical.

Frequently Asked Questions (FAQ)

Q: Can the UPT2G101MHD6 directly replace the EEU-EE2G101 without PCB modification?

A: Yes. The UPT2G101MHD6 maintains identical lead spacing (0.295" / 7.50mm) and diameter (0.709" / 18.00mm), ensuring mechanical and electrical compatibility with existing through-hole footprints.

Q: What is the primary difference between UPT2G101MHD and UPT2G101MHD6?

A: Both parts share identical electrical specifications and 5000-hour lifetime ratings. The primary difference is physical diameter: UPT2G101MHD measures 0.630" (16.00mm), while UPT2G101MHD6 measures 0.709" (18.00mm). Selection depends on available board space.

Q: Is the LDQ2G101MERYGA suitable for high-reliability applications?

A: The LDQ2G101MERYGA carries a 2000-hour lifetime rating at 105°C, compared to 10,000 hours for the original EEU-EE2G101. This reduced endurance rating limits suitability to applications with lower thermal stress or shorter operational lifespans.

Q: Are all substitutes RoHS compliant?

A: Yes. All three substitute parts carry ROHS3 compliance certification, matching the regulatory status of the original EEU-EE2G101.

Q: Do the substitute parts maintain the same ripple current handling?

A: Ripple current ratings vary across substitutes. The EEU-EE2G101 supports 824 mA at 120 Hz. The UPT series supports 580 mA at 120 Hz, while the LDQ series supports 700 mA at 120 Hz. Applications requiring maximum ripple current handling should reference the specific ripple current specifications for the selected substitute.
