Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEF-SL0E101R is determined by the following electrical and mechanical parameters:

Mandatory Compatibility Parameters:

• Capacitance: 100 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Aluminum Polymer (exact match required)

Allowable Upgrade Parameters:

• Voltage Rating: May be equal to or greater than 2.5 V
• ESR: May be equal to or lower than 9 mOhm
• Lifetime @ Temperature: May be equal to or greater than 1000 Hrs @ 105°C
• Operating Temperature Range: May be equal to or wider than -40°C to 105°C

The substitute parts EEF-SX0G101R and EEF-SX0G101ER meet all mandatory compatibility requirements and provide electrical upgrades in voltage rating and thermal lifetime specifications.

Parameter Comparison

Engineering Selection Recommendations

EEF-SX0G101ER is the recommended substitute for new designs and ongoing production. This part carries Active product status, is RoHS3 compliant, and REACH unaffected. It provides upgraded voltage rating (4 V versus 2.5 V), extended thermal lifetime (2000 Hrs @ 105°C versus 1000 Hrs @ 105°C), and wider operating temperature range (-55°C to 105°C versus -40°C to 105°C). Packaging is Tape & Reel (TR) format with 7147 units in stock.

EEF-SX0G101R is an alternative substitute with identical electrical specifications to EEF-SX0G101ER but carries Not For New Designs status. This part is suitable only for legacy production support or replacement applications where design changes are not feasible. RoHS3 compliance and REACH unaffected status are maintained. Packaging is Tape & Reel (TR) format with 3679 units in stock.

Both substitute parts maintain identical mechanical compatibility and ESR characteristics while providing electrical performance upgrades suitable for applications originally designed for the EEF-SL0E101R.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0G101ER or EEF-SX0G101R be used as direct replacements for EEF-SL0E101R?

A: Yes. Both substitute parts maintain identical capacitance (100 µF), tolerance (±20%), package (2917 Metric), and ESR (9 mOhm) specifications. The higher voltage rating (4 V) and extended thermal lifetime represent electrical upgrades compatible with circuits designed for the original 2.5 V part.

Q: What is the difference between EEF-SX0G101R and EEF-SX0G101ER?

A: Both parts have identical electrical and mechanical specifications. The primary difference is product status: EEF-SX0G101ER is Active (recommended for new designs), while EEF-SX0G101R is Not For New Designs. EEF-SX0G101ER is the preferred choice for new production.

Q: Are there packaging differences between the main part and substitutes?

A: The main part EEF-SL0E101R uses Cut Tape (CT) & Digi-Reel packaging. Both substitute parts use Tape & Reel (TR) packaging. The physical component dimensions and land pattern remain identical (2917 Metric package, 7.30mm × 4.30mm).

Q: Can the 4 V rated substitutes be used in circuits designed for 2.5 V?

A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible with lower voltage circuit designs. The 4 V rated parts will function correctly in applications originally specified for 2.5 V operation.

Q: What is the temperature range difference?

A: The EEF-SL0E101R operates from -40°C to 105°C. Both substitute parts extend the lower temperature limit to -55°C, providing wider operating range suitable for industrial and extended temperature applications.
