EEF-SL0D181R Equivalent & Substitute Parts

Part Overview

The EEF-SL0D181R is a 180 µF, 2 V aluminum polymer surface mount capacitor manufactured by Panasonic Electronic Components in the 2917 (7343 Metric) package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production support and design continuity. The SP-Cap SL series has been superseded by the SP-Cap SX series, which offers improved lifetime ratings and extended operating temperature ranges while maintaining identical electrical and mechanical specifications for core applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the EEF-SL0D181R is determined by the following criteria:

Direct Electrical Equivalents (Same Voltage Rating): Parts maintaining 180 µF capacitance, 2 V voltage rating, ±20% tolerance, and 9 mOhm ESR are classified as direct substitutes. These include EEF-SX0D181ER and EEF-SX0D181R from the SP-Cap SX series.

Upgraded Voltage Rating Substitutes: Parts with identical capacitance, tolerance, and ESR but rated for higher voltages (2.5 V or 4 V) are functional upgrades. These include EEF-SX0E181ER, EEF-SX0E181R, and EEF-SX0G181ER. Higher voltage ratings provide additional design margin and are electrically compatible in applications where the original 2 V rating is sufficient.

Common Substitution Parameters:

• Capacitance: 180 µF (fixed)
• Tolerance: ±20% (fixed)
• ESR: 9 mOhm (fixed)
• Package: 2917 (7343 Metric) (fixed)
• Mounting: Surface Mount (fixed)
• Physical Dimensions: 0.287" L x 0.169" W (7.30 mm x 4.30 mm) (fixed)

Parameter Comparison

Engineering Selection Recommendations

For Active Production (Recommended Primary Choices):

EEF-SX0D181ER is the preferred direct substitute for the obsolete EEF-SL0D181R. It maintains identical electrical specifications (180 µF, 2 V, 9 mOhm ESR) while offering doubled lifetime (2000 Hrs @ 105°C versus 1000 Hrs), extended low-temperature operation (-55°C versus -40°C), and active product status. RoHS3 and REACH compliance certifications are included.

EEF-SX0E181ER provides an upgraded voltage rating (2.5 V) with the same active status and compliance certifications. This option is suitable for applications where additional voltage margin is beneficial without circuit redesign.

EEF-SX0G181ER offers the highest voltage rating (4 V) within the substitute family, maintaining active status and full compliance. This option provides maximum design flexibility for future applications.

For Existing Inventory Management:

EEF-SX0D181R and EEF-SX0E181R are classified as "Not For New Designs" but remain electrically and mechanically compatible. These parts may be used for legacy system support or inventory consolidation where product status restrictions do not apply.

Compliance Considerations:

All SP-Cap SX series substitutes (EEF-SX0D181ER, EEF-SX0E181ER, EEF-SX0G181ER) carry RoHS3 Compliant and REACH Unaffected certifications, meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0D181ER be used as a direct replacement for EEF-SL0D181R without circuit modification?

A: Yes. Both parts share identical capacitance (180 µF), voltage rating (2 V), tolerance (±20%), ESR (9 mOhm), and package dimensions (2917 / 7343 Metric). The EEF-SX0D181ER is a direct electrical and mechanical substitute. The improved lifetime rating (2000 Hrs versus 1000 Hrs @ 105°C) and extended operating temperature range (-55°C to 105°C versus -40°C to 105°C) provide additional performance margin.

Q: What is the difference between EEF-SX0D181ER and EEF-SX0D181R?

A: Both parts are electrically and mechanically identical. The primary difference is product status: EEF-SX0D181ER is Active, while EEF-SX0D181R is Not For New Designs. For new designs, EEF-SX0D181ER is the recommended choice.

Q: Can higher voltage-rated substitutes (2.5 V or 4 V) be used in place of the 2 V rated EEF-SL0D181R?

A: Yes. EEF-SX0E181ER (2.5 V) and EEF-SX0G181ER (4 V) are electrically compatible substitutes. Higher voltage ratings do not affect circuit operation when the applied voltage remains at or below 2 V. These upgrades provide additional design margin and are suitable for applications where voltage headroom is desired.

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

A: The EEF-SL0D181R is supplied in bulk packaging, while all SP-Cap SX substitutes are supplied in Tape & Reel (TR) format. Physical dimensions and land patterns remain identical (0.287" L x 0.169" W / 7.30 mm x 4.30 mm). Packaging format does not affect electrical or mechanical compatibility.

Q: What is the ripple current specification for the substitute parts?

A: The SP-Cap SX series substitutes (EEF-SX0D181ER, EEF-SX0E181ER, EEF-SX0G181ER) are rated for 6.3 A ripple current at 100 kHz. This specification is not provided for the original EEF-SL0D181R but indicates improved high-frequency performance in the substitute series.

Q: Are all substitute parts RoHS and REACH compliant?

A: All SP-Cap SX series substitutes carry RoHS3 Compliant and REACH Unaffected certifications. The original EEF-SL0D181R compliance status is not specified in the provided data.
