Key Parameters

Substitute Part Grouping Explanation

Substitution for the EEF-SL0E151R is determined by the following critical parameters: capacitance value (150 µF), package type (2917 Metric), mounting method (surface mount), and physical dimensions (0.287" L x 0.169" W). The voltage rating and lifetime specifications define substitution categories.

Direct equivalents maintain identical voltage rating (2.5 V) and ESR (9 mOhm) while offering improved product status and extended lifetime. Upgrade substitutes increase voltage rating above the original specification while maintaining all other electrical and mechanical parameters. Similar substitutes reduce voltage rating below the original specification.

Parameter Comparison

Engineering Selection Recommendations

EEF-SX0E151ER serves as the primary direct equivalent, offering identical electrical specifications (150 µF, 2.5 V, 9 mOhm ESR) with active product status, extended lifetime (2000 hours versus 1000 hours), and expanded operating temperature range (-55°C to 105°C). This part is ROHS3 compliant and REACH unaffected.

EEF-SX0G151ER and EEF-SX0J151ER are upgrade substitutes suitable for applications where higher voltage margins are acceptable. Both maintain 150 µF capacitance, 9 mOhm ESR, and 2000-hour lifetime with active status and full compliance certifications. EEF-SX0G151ER provides 4 V rating; EEF-SX0J151ER provides 6.3 V rating.

EEF-SX0D151ER is a similar substitute with reduced voltage rating (2 V) and active status. This part is suitable only for applications with maximum operating voltage of 2 V or lower.

All substitute parts maintain identical package type (2917 Metric), physical dimensions, and surface mount configuration, ensuring PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0E151ER directly replace EEF-SL0E151R?

A: Yes. Both parts share identical capacitance (150 µF), voltage rating (2.5 V), ESR (9 mOhm), and package type (2917 Metric). EEF-SX0E151ER offers improved product status (active versus obsolete), extended lifetime (2000 hours versus 1000 hours), and wider operating temperature range (-55°C to 105°C versus -40°C to 105°C).

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents (EEF-SX0E151ER) maintain the original voltage specification of 2.5 V. Upgrade substitutes (EEF-SX0G151ER at 4 V and EEF-SX0J151ER at 6.3 V) increase voltage rating while preserving all other parameters. Upgrade substitutes are suitable when circuit design permits higher voltage components.

Q: Are all substitute parts RoHS and REACH compliant?

A: EEF-SX0E151ER, EEF-SX0G151ER, and EEF-SX0J151ER are ROHS3 compliant and REACH unaffected. EEF-SX0D151ER is also ROHS3 compliant and REACH unaffected. The original EEF-SL0E151R compliance status is not specified in available documentation.

Q: Does packaging format affect electrical performance?

A: No. The original part uses Cut Tape (CT) packaging; substitute parts use Tape & Reel (TR) packaging. Packaging format affects procurement and handling only, not electrical characteristics or PCB performance.

Q: Can EEF-SX0D151ER replace EEF-SL0E151R?

A: No. EEF-SX0D151ER has a reduced voltage rating of 2 V, below the original 2.5 V specification. This part is suitable only for applications with maximum operating voltage of 2 V or lower.
