Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SLG150M1.4X7.3 is determined by the following critical parameters:

Capacitance value must remain 150 µF to maintain circuit functionality. Tolerance of ±20% is acceptable across all candidates. The package and case designation 2917 (7343 Metric) is mandatory for mechanical and electrical compatibility on the PCB. Surface mount mounting type is required. Operating temperature range of -55°C ~ 105°C must be supported. ESR of 9 mOhm establishes the electrical performance baseline. Lifetime specification of 2000 hours at 105°C defines reliability expectations. Polymer type ensures consistent electrical characteristics. Voltage rating may exceed the original 2 V specification without compromising circuit operation, provided the application does not require voltage derating. RoHS3 compliance and REACH unaffected status are required for regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0J151ER from Panasonic Electronic Components is a direct functional substitute for the 2SLG150M1.4X7.3. Both components share identical capacitance, tolerance, ESR, lifetime rating, operating temperature range, package dimensions, and mounting configuration. The Panasonic part carries Active product status, ensuring continued availability and manufacturing support, whereas the Rubycon part is designated Not For New Designs. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. The EEF-SX0J151ER features a higher voltage rating of 6.3 V compared to the original 2 V specification, which provides additional design margin and does not introduce compatibility issues in applications operating at or below 2 V. The increased ripple current capability of 6.3 A at 100 kHz in the Panasonic part exceeds the original 2.7 A specification, offering improved thermal performance under high-frequency ripple conditions.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0J151ER replace the 2SLG150M1.4X7.3 in existing designs?

A: Yes. Both components share the same capacitance value, tolerance, ESR, lifetime rating, operating temperature range, and 2917 (7343 Metric) package. The higher voltage rating of the Panasonic part does not compromise compatibility in circuits designed for 2 V operation.

Q: What is the significance of the voltage rating difference?

A: The EEF-SX0J151ER is rated for 6.3 V, while the original part is rated for 2 V. In applications operating at 2 V or below, the higher voltage rating of the substitute provides additional design margin without affecting circuit performance.

Q: Are the physical dimensions identical?

A: Yes. Both components are packaged in the 2917 (7343 Metric) case with identical length, width, and maximum seated height specifications. PCB land patterns and mounting procedures remain unchanged.

Q: What is the difference in ripple current capability?

A: The EEF-SX0J151ER supports 6.3 A ripple current at 100 kHz, compared to 2.7 A for the original part. This enhanced capability reduces thermal stress in high-frequency applications.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 2SLG150M1.4X7.3 and EEF-SX0J151ER are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the Rubycon part marked as Not For New Designs?

A: This designation indicates that Rubycon has discontinued active promotion and development of this part number. The Panasonic EEF-SX0J151ER, with Active product status, is the recommended choice for new designs and ongoing production.
