Substitute Part Grouping Explanation
Substitute parts for the EEF-SX0J181ER are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:
- Capacitance value: 180 µF (exact match required)
- Voltage rating: 6.3 V (exact match required)
- Capacitor type: Aluminum Polymer (exact match required)
- Tolerance: ±20% (exact match required)
- ESR: 9 mOhm (exact match required)
- Lifetime rating: 2000 Hrs @ 105°C (exact match required)
- Operating temperature range: -55°C ~ 105°C (exact match required)
- Package: 2917 (7343 Metric) (exact match required)
- Mounting: Surface Mount, Tape & Reel (exact match required)
- Ripple current capability: 6.3 A @ 100 kHz (exact match required)
Only components meeting all of these specifications are considered parametric equivalents and direct substitutes.

Frequently Asked Questions (FAQ)
Q: Can the 875035119002 be used as a direct replacement for the EEF-SX0J181ER?
A: Yes. Both parts are parametric equivalents with identical capacitance (180 µF), voltage rating (6.3 V), ESR (9 mOhm), lifetime rating (2000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), package (2917/7343 Metric), and ripple current capability (6.3 A @ 100 kHz). No circuit modifications are required.
Q: Are there any differences in physical dimensions between these parts?
A: No. Both parts have identical dimensions of 0.287" L x 0.169" W x 0.079" H (7.30mm x 4.30mm x 2.00mm) and use the same 2917 (7343 Metric) package. They are mechanically interchangeable on PCBs designed for either part.
Q: Do both parts meet the same compliance standards?
A: Yes. Both the EEF-SX0J181ER and 875035119002 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Both carry the same HTSUS code (8532.22.0020).
Q: What is the Moisture Sensitivity Level (MSL) for the Panasonic part?
A: The MSL rating is not specified in the provided data for the EEF-SX0J181ER. The Würth Elektronik 875035119002 is rated MSL 3 (168 Hours). Consult Panasonic datasheets for the EEF-SX0J181ER MSL specification if moisture sensitivity is a critical factor in your manufacturing process.
Q: Can these parts be used interchangeably in high-ripple-current applications?
A: Yes. Both parts are rated for 6.3 A ripple current at 100 kHz and share identical ESR characteristics (9 mOhm), making them suitable for equivalent performance in high-frequency ripple current applications.
