Substitute Part Grouping Explanation

Substitution of the ECO-S1VA152BA is determined by the following critical parameters: capacitance value (1500 µF), tolerance (±20%), rated voltage (35 V minimum), package type (radial, can snap-in), lead spacing (10.00 mm), physical dimensions (22.00 mm diameter, 27.00 mm height maximum), and operating temperature range (-40°C to 105°C). All substitute parts maintain identical capacitance, tolerance, and package specifications. Substitute parts are grouped into three categories:

Direct Equivalent (381LX152M035H202): Identical electrical and mechanical specifications with matching 35 V rating and 3000-hour lifetime at 105°C. Height is reduced to 22.00 mm, maintaining compatibility with the snap-in mounting interface.

Voltage Upgrades (381LX152M050H012, 381LX152M063H012): Higher rated voltages (50 V and 63 V respectively) with identical capacitance and tolerance. These parts are electrically compatible in applications where the original 35 V rating is sufficient, as higher-rated components operate safely at lower voltages. Physical dimensions remain consistent with the original specification.

Parametric Equivalent (381LX152M035H012): Matches all electrical parameters of the original part with identical 35 V rating, ESR, and lifetime. Height specification is 27.00 mm, matching the original seated height.

Engineering Selection Recommendations

For Direct Replacement: Select 381LX152M035H012 (Parametric Equivalent) when exact electrical and mechanical specifications are required. This part maintains identical ESR (287 mOhm @ 120 Hz), voltage rating (35 V), and lifetime (3000 Hrs @ 105°C). Product status is active with ROHS3 compliance and REACH unaffected designation.

For Height-Constrained Applications: Select 381LX152M035H202 (Direct Equivalent) when PCB space is limited vertically. This part reduces seated height from 27.00 mm to 22.00 mm while maintaining all electrical parameters and 35 V rating. Product status is active with ROHS3 compliance.

For Enhanced Performance or Margin: Select 381LX152M050H012 or 381LX152M063H012 (Voltage Upgrades) when higher voltage margin is beneficial. The 50 V variant offers reduced ESR (155 mOhm @ 120 Hz) and increased ripple current capability (1.25 A @ 120 Hz). The 63 V variant provides maximum voltage headroom with ESR of 235 mOhm @ 120 Hz and ripple current of 1.5 A @ 120 Hz. Both maintain active product status and ROHS3 compliance. Physical dimensions match the original 27.00 mm seated height.

All substitute parts are manufactured by Cornell Dubilier Electronics (CDE), series 381LX, with active product status and ROHS3 compliance, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can 381LX152M035H202 be used as a direct replacement for ECO-S1VA152BA?

A: Yes, with one consideration. The 381LX152M035H202 maintains identical capacitance (1500 µF), tolerance (±20%), voltage rating (35 V), and operating temperature range (-40°C to 105°C). However, its seated height is 22.00 mm compared to the original 27.00 mm. Verify that the reduced height does not conflict with PCB layout or mechanical constraints before substitution.

Q: What is the difference between the direct equivalent and parametric equivalent options?

A: The 381LX152M035H202 (Direct Equivalent) has a reduced seated height of 22.00 mm. The 381LX152M035H012 (Parametric Equivalent) maintains the original 27.00 mm seated height and identical ESR specification (287 mOhm @ 120 Hz). Both have identical electrical performance; selection depends on available PCB space.

Q: Can I use a 50 V or 63 V rated capacitor in place of the 35 V original?

A: Yes. The 381LX152M050H012 (50 V) and 381LX152M063H012 (63 V) are electrically compatible in applications designed for 35 V operation. Higher-rated capacitors operate safely at lower voltages. These upgrades offer reduced ESR and increased ripple current capability. Physical dimensions remain compatible with the original snap-in mounting interface.

Q: Are all substitute parts RoHS compliant?

A: Yes. All Cornell Dubilier Electronics 381LX series substitute parts are ROHS3 compliant. The original Panasonic ECO-S1VA152BA RoHS status is not specified in the provided data.

Q: What is the lead spacing for all parts in this comparison?

A: All parts, including the original ECO-S1VA152BA and all substitute options, have identical lead spacing of 0.394" (10.00 mm), ensuring compatibility with existing PCB footprints.

Q: Are there inventory considerations for these substitute parts?

A: All substitute parts are listed as active products with new original stock available. The 381LX152M050H012 has 958 pieces in stock, 381LX152M063H012 has 845 pieces, 381LX152M035H202 has 878 pieces, and 381LX152M035H012 has 787 pieces available.
