Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEF-SX0D181R is determined by the following criteria:

Parametric Equivalents maintain identical electrical specifications: 180 µF capacitance, 2 V voltage rating, ±20% tolerance, 9 mOhm ESR, and 2000 Hrs @ 105°C lifetime. These parts are interchangeable without circuit modification.

Upgrade Substitutes increase the voltage rating while maintaining all other electrical parameters (180 µF capacitance, ±20% tolerance, 9 mOhm ESR, 2000 Hrs @ 105°C lifetime). Higher voltage ratings provide additional design margin and are compatible with circuits designed for 2 V operation. All substitute parts maintain the identical 2917 (7343 Metric) package footprint and surface mount configuration.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent): Select EEF-SX0D181ER. This part maintains identical electrical specifications to the EEF-SX0D181R while offering Active product status, ensuring long-term availability and supply chain stability. Both parts are ROHS3 compliant and REACH unaffected.

For Voltage Margin Enhancement: Select EEF-SX0E181ER (2.5 V) or EEF-SX0G181ER (4 V). These upgrades provide additional voltage headroom while preserving all other electrical characteristics. Both are Active products with ROHS3 compliance. The 4 V variant (EEF-SX0G181ER) offers the greatest design margin and is recommended for applications requiring enhanced reliability or operating in variable supply conditions.

Inventory Considerations: EEF-SX0E181R offers the highest stock availability (10915 Pcs) among all variants, followed by EEF-SX0D181R (4173 Pcs). For time-sensitive applications, inventory levels should be verified with the supplier.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0D181ER directly replace EEF-SX0D181R? A: Yes. EEF-SX0D181ER is a parametric equivalent with identical capacitance (180 µF), voltage rating (2 V), tolerance (±20%), ESR (9 mOhm), and package (2917 / 7343 Metric). The primary difference is product status: EEF-SX0D181ER is Active, while EEF-SX0D181R is Not For New Designs.

Q: Can I use a higher voltage-rated substitute in place of the 2 V EEF-SX0D181R? A: Yes. Higher voltage ratings (2.5 V or 4 V) are compatible with circuits designed for 2 V operation. The capacitor will operate within its voltage margin, which is acceptable for legacy system support. All substitute parts maintain identical capacitance, tolerance, ESR, and package dimensions.

Q: Are all substitute parts in the same package? A: Yes. All listed parts use the 2917 (7343 Metric) surface mount package with identical footprint dimensions (0.287" L x 0.169" W / 7.30 mm x 4.30 mm) and maximum seated height (0.079" / 2.00 mm). No PCB layout modifications are required.

Q: What is the difference between EEF-SX0D181R and EEF-SX0D181ER? A: Both parts are electrically identical (180 µF, 2 V, ±20%, 9 mOhm, 2000 Hrs @ 105°C). The suffix "ER" indicates Active product status with enhanced ripple current specification (6.3 A @ 100 kHz). EEF-SX0D181R is Not For New Designs.

Q: Which substitute offers the best long-term availability? A: EEF-SX0D181ER and EEF-SX0E181ER both carry Active product status, ensuring continued manufacturing and supply. EEF-SX0G181ER (4 V variant) is also Active and provides the highest voltage margin for enhanced reliability.

Q: Are all parts ROHS3 compliant? A: Yes. All listed parts (EEF-SX0D181R, EEF-SX0D181ER, EEF-SX0E181R, EEF-SX0E181ER, and EEF-SX0G181ER) are ROHS3 compliant and REACH unaffected.
