Equivalent & Substitute Parts for 2.5SLG150M1.4X7.3

Part Overview

The 2.5SLG150M1.4X7.3 is a 150 µF aluminum polymer capacitor manufactured by Rubycon, rated at 2.5 V with a tolerance of ±20%. This component is classified as not for new designs, indicating its legacy status in the product portfolio. The part is housed in a 2917 (7343 Metric) surface mount package with an ESR of 9 mOhm and a rated lifetime of 2000 hours at 105°C. Finding equivalent substitute parts is necessary for applications requiring active production support, improved availability, or design flexibility while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the 2.5SLG150M1.4X7.3 is determined by the following critical parameters:

• Capacitance Value: 150 µF (exact match required)
• Package Type: 2917 (7343 Metric) surface mount (exact match required for PCB compatibility)
• Tolerance: ±20% (acceptable range for general purpose applications)
• Type: Aluminum Polymer (functional equivalence)
• ESR: 9 mOhm (electrical performance baseline)
• Lifetime Rating: 2000 Hrs @ 105°C (reliability specification)
• Operating Temperature Range: -55°C ~ 105°C (environmental compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part EEF-SX0J151ER meets all mechanical and electrical compatibility criteria. While the voltage rating differs (6.3 V versus 2.5 V), the higher voltage rating of the substitute provides functional equivalence in applications where the original 2.5 V specification is not a limiting constraint. Both parts share identical capacitance, package dimensions, ESR characteristics, and thermal ratings.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0J151ER from Panasonic is a qualified substitute for the 2.5SLG150M1.4X7.3. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Panasonic part carries an active product status, ensuring continued availability and manufacturing support compared to the legacy Rubycon component.

The primary consideration for substitution is the height difference: the Panasonic part measures 0.079" (2.00 mm) seated height versus 0.043" (1.10 mm) for the Rubycon part. This dimensional variance must be evaluated against PCB layout constraints and available board space. The higher voltage rating (6.3 V) of the substitute provides additional design margin in applications where the original 2.5 V specification permits such substitution.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0J151ER replace the 2.5SLG150M1.4X7.3 in all applications?

A: The EEF-SX0J151ER is mechanically and electrically compatible for applications where the 2.5 V voltage specification is not a hard constraint. The higher 6.3 V rating of the substitute provides functional equivalence. However, the seated height difference (2.00 mm versus 1.10 mm) must be verified against PCB layout requirements.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Rubycon versus Panasonic), product status (legacy versus active), voltage rating (2.5 V versus 6.3 V), seated height (1.10 mm versus 2.00 mm), and ripple current capability (2.7 A versus 6.3 A at 100 kHz). Capacitance, tolerance, ESR, package type, and thermal ratings are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the 2.5SLG150M1.4X7.3 and EEF-SX0J151ER are ROHS3 compliant and REACH unaffected.

Q: Does the package footprint remain the same?

A: Yes, both parts use the 2917 (7343 Metric) surface mount package with identical length and width dimensions (7.30 mm x 4.30 mm). The seated height differs, which may affect PCB clearance in space-constrained designs.

Q: What is the significance of the product status difference?

A: The 2.5SLG150M1.4X7.3 is marked as not for new designs, indicating Rubycon has discontinued active development and support. The EEF-SX0J151ER carries active status from Panasonic, ensuring ongoing manufacturing, quality support, and availability for new production runs.
