Panasonic EEF-SL0E101ER Equivalent & Substitute Parts

Part Overview

The Panasonic EEF-SL0E101ER is a 100 µF, 2.5 V aluminum polymer surface mount capacitor in the 2917 (7343 Metric) package. This component is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. The SP-Cap SL series has been superseded by newer polymer capacitor lines with improved performance characteristics and extended product lifecycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the EEF-SL0E101ER is determined by the following criteria:

Electrical Parameters (Must Match or Exceed):

• Capacitance: 100 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: Minimum 2.5 V (higher ratings acceptable for backward compatibility)
• ESR: 9 mOhm (exact match required)
• Operating Temperature Range: Must encompass -40°C ~ 105°C minimum

Mechanical Parameters (Must Match):

• Package / Case: 2917 (7343 Metric)
• Mounting Type: Surface Mount
• Physical Dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm)

Substitute Categories:

1. Upgrade Substitutes – Higher voltage rating with improved lifetime specifications
2. Parametric Equivalents – Identical electrical and mechanical specifications with different packaging options

Engineering Selection Recommendations

For New Designs and Active Production: Select EEF-SX0G101ER. This part is classified as Active and offers superior performance characteristics: 4 V voltage rating (backward compatible with 2.5 V applications), doubled lifetime rating (2000 Hrs @ 105°C versus 1000 Hrs), extended operating temperature range (-55°C ~ 105°C), and increased ripple current capability (6.3 A @ 100 kHz). RoHS3 and REACH compliance certifications are provided.

For Legacy System Maintenance: EEF-SL0E101R provides parametric equivalence to the original EEF-SL0E101ER with identical electrical specifications and operating temperature range. This part is available in Cut Tape (CT) & Digi-Reel® packaging, offering flexibility for lower-volume applications.

Not Recommended for New Designs: EEF-SX0G101R carries a "Not For New Designs" status and should be avoided for new product development, though it remains available for legacy system support if EEF-SX0G101ER is unavailable.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0G101ER replace EEF-SL0E101ER in existing designs? A: Yes. The EEF-SX0G101ER maintains identical capacitance (100 µF), tolerance (±20%), ESR (9 mOhm), and package dimensions (2917 / 7343 Metric). The 4 V rating is backward compatible with 2.5 V circuit requirements. The extended lifetime (2000 Hrs @ 105°C) and lower operating temperature limit (-55°C) provide improved reliability margins.

Q: What is the difference between EEF-SX0G101ER and EEF-SX0G101R? A: Both parts share identical electrical specifications and package dimensions. EEF-SX0G101ER is classified as Active with full RoHS3 and REACH compliance documentation. EEF-SX0G101R is classified as "Not For New Designs" and should not be selected for new product development.

Q: Are there packaging differences between substitute options? A: EEF-SX0G101ER and EEF-SX0G101R are supplied in Tape & Reel (TR) packaging. EEF-SL0E101R is available in Cut Tape (CT) & Digi-Reel® packaging, suitable for applications requiring smaller order quantities or manual assembly processes.

Q: Does the higher voltage rating of EEF-SX0G101ER affect circuit performance? A: No. A 4 V rated capacitor operates safely in 2.5 V circuits. The higher voltage rating does not alter capacitance value, ESR, or frequency response characteristics. It provides additional safety margin and improved reliability in the application.

Q: What compliance certifications apply to substitute parts? A: EEF-SX0G101ER is RoHS3 Compliant and REACH Unaffected. EEF-SL0E101R compliance certifications are not specified in available documentation. Verify compliance requirements with your procurement or quality assurance department for specific applications.
