2SZE100M1.4X7.3 Equivalent & Substitute Parts

Part Overview

The 2SZE100M1.4X7.3 is a 100 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the 2917 (7343 Metric) surface mount package. This component is classified as Not For New Designs, indicating it has been superseded in Rubycon's product portfolio. The part is suitable for general purpose applications requiring low ESR characteristics in compact form factors. Due to its discontinued status, identifying compatible substitute components is essential for ongoing production support and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SZE100M1.4X7.3 is determined by the following critical parameters:

• Capacitance Value: Must be 100 µF (exact match required)
• Package Type: Must be 2917 (7343 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount
• Type: Must be Aluminum Polymer
• Tolerance: Must be ±20% or tighter
• Operating Temperature Range: Must support -55°C ~ 105°C minimum
• Compliance: Must maintain ROHS3 compliance

The substitute part EEF-CX0J101R meets all mechanical and electrical compatibility criteria. While the voltage rating differs (6.3 V vs. 2 V), this represents an upgrade path suitable for applications where the original 2 V specification can accommodate higher voltage-rated components. The identical package footprint, capacitance value, tolerance, temperature range, and compliance status establish direct substitutability.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0J101R from Panasonic is the qualified substitute for the 2SZE100M1.4X7.3. Selection is supported by the following factors:

• Compliance Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.
• Active Product Status: The Panasonic component is in active production, providing supply chain stability and long-term availability compared to the discontinued Rubycon part.
• Mechanical Compatibility: Identical package footprint (2917/7343 Metric) and surface mount configuration enable direct PCB layout compatibility.
• Electrical Equivalence: Matching capacitance (100 µF), tolerance (±20%), and operating temperature range (-55°C ~ 105°C) establish functional equivalence.
• Voltage Upgrade Path: The higher voltage rating (6.3 V) of the substitute provides design margin in applications originally specified at 2 V, with no functional degradation.

The increased ESR (15 mOhm vs. 5 mOhm) and maximum height (0.075" vs. 0.055") should be evaluated against specific application requirements for ripple current handling and board clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0J101R directly replace the 2SZE100M1.4X7.3 on existing PCBs?

A: Yes. Both components share identical footprint dimensions (7.30mm x 4.30mm) and the same 2917 (7343 Metric) package. The maximum height difference (0.075" vs. 0.055") must be confirmed against board clearance specifications. No PCB layout modifications are required.

Q: Why does the substitute have a higher voltage rating (6.3 V vs. 2 V)?

A: The EEF-CX0J101R is specified at 6.3 V, which represents a higher voltage-rated component from Panasonic's active product line. This does not prevent substitution in 2 V applications; the component will operate safely at lower voltages with increased design margin.

Q: Are there differences in electrical performance between these parts?

A: The primary electrical difference is ESR: the 2SZE100M1.4X7.3 has 5 mOhm while the EEF-CX0J101R has 15 mOhm. Both maintain 2000 Hrs @ 105°C lifetime and identical operating temperature range. Applications sensitive to ripple current or thermal dissipation should account for the higher ESR of the substitute.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the 2SZE100M1.4X7.3 has been discontinued by Rubycon and is no longer recommended for new product development. Existing inventory may be available, but long-term supply cannot be guaranteed. The EEF-CX0J101R, with Active status, is the recommended path for ongoing production and new designs.

Q: Are both components RoHS compliant?

A: Yes. Both the 2SZE100M1.4X7.3 and EEF-CX0J101R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can the substitute be used in high-frequency ripple current applications?

A: The EEF-CX0J101R is rated for 5.1 A @ 100 kHz ripple current. Applications requiring higher ripple current handling should evaluate this specification against the original design requirements.
