Key Parameters

Substitute Part Grouping Explanation

Substitution for the EEF-SL0D151R is determined by the following critical parameters: capacitance value (150 µF), package type (2917 / 7343 Metric), mounting configuration (surface mount), and ESR specification (9 mOhm). Voltage rating serves as a key differentiator; substitute parts with equal or higher voltage ratings are electrically compatible with the original 2 V specification. Operating temperature range and lifetime rating at 105°C are secondary considerations for application suitability.

The substitute parts are grouped into two categories:

Upgrade Path (Panasonic SP-Cap SL/SX Series): Parts EEF-SL0E151R, EEF-SX0E151ER, EEF-SX0G151ER, and EEF-SX0J151ER maintain identical capacitance and package dimensions while offering higher voltage ratings (2.5 V to 6.3 V) and improved lifetime specifications (2000 Hrs @ 105°C for SX series).

Direct Equivalent (Murata ECAS Series): Part ECASD40D157M009K00 provides identical electrical specifications (150 µF, 2 V, 9 mOhm, 1000 Hrs @ 105°C) with equivalent package footprint and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement of EEF-SL0D151R with minimal design modification, ECASD40D157M009K00 (Murata) provides identical electrical and thermal specifications. Both parts are obsolete; however, ECASD40D157M009K00 maintains ROHS3 compliance.

For new designs or production transitions, Panasonic SP-Cap SX series parts (EEF-SX0E151ER, EEF-SX0G151ER, EEF-SX0J151ER) are recommended. These active production parts offer extended lifetime (2000 Hrs @ 105°C versus 1000 Hrs), expanded operating temperature range (-55°C to 105°C), ROHS3 compliance, and REACH unaffected status. Voltage rating selection depends on circuit requirements: EEF-SX0E151ER (2.5 V) for minimal voltage margin, EEF-SX0G151ER (4 V) for standard applications, or EEF-SX0J151ER (6.3 V) for designs requiring additional voltage headroom.

Note: EEF-SX series parts have maximum seated height of 0.079" (2.00mm) compared to 0.071" (1.80mm) for the original part. PCB layout verification is required for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0G151ER (4 V) be used as a direct replacement for EEF-SL0D151R (2 V)?

A: Yes. The 4 V rated part is electrically compatible with 2 V circuit requirements. Higher voltage rating provides additional safety margin and does not affect circuit operation. Capacitance (150 µF), tolerance (±20%), ESR (9 mOhm), and package footprint (2917 / 7343 Metric) are identical.

Q: What is the impact of the height difference between EEF-SL0D151R (1.80mm) and EEF-SX series (2.00mm)?

A: The 0.20mm height increase must be evaluated against PCB clearance and component stacking constraints. For most applications with standard PCB spacing, this difference is acceptable. Verify clearance in your specific assembly design before implementation.

Q: Are Panasonic SP-Cap SX series parts (EEF-SX0E151ER, EEF-SX0G151ER, EEF-SX0J151ER) suitable for production use?

A: Yes. All three SP-Cap SX variants are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for new designs and ongoing production. The extended 2000-hour lifetime at 105°C provides improved reliability compared to the obsolete 1000-hour rated original part.

Q: What is the difference between EEF-SL0E151R and EEF-SX0E151ER?

A: Both parts share 150 µF capacitance, 2.5 V rating, and 9 mOhm ESR. EEF-SL0E151R (SP-Cap SL series) is obsolete with 1000-hour lifetime, while EEF-SX0E151ER (SP-Cap SX series) is active production with 2000-hour lifetime, extended temperature range (-55°C to 105°C), and compliance certifications. EEF-SX0E151ER is the recommended upgrade path.

Q: Can ECASD40D157M009K00 (Murata) be used interchangeably with Panasonic parts?

A: Yes, for the original 2 V specification. ECASD40D157M009K00 provides identical capacitance, voltage, ESR, and lifetime ratings with compatible 2917 package footprint. However, it is also obsolete. For new production, Panasonic SP-Cap SX series is preferred due to active status and extended specifications.

Q: What ripple current capability should be considered for these parts?

A: EEF-SX series parts (EEF-SX0E151ER, EEF-SX0G151ER, EEF-SX0J151ER) support 6.3 A ripple current at 100 kHz. The original EEF-SL0D151R and ECASD40D157M009K00 do not specify ripple current in the provided data. For high-frequency ripple current applications, SP-Cap SX series is the appropriate selection.
