Tolerance: ±20% (exact match required)
Voltage Rating: 63 V minimum (equal or higher acceptable)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Case Diameter: 0.866" (22.00 mm) (exact match required)
Height: 1.063" (27.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)

Substitute parts are categorized as follows:

Direct Equivalents maintain identical electrical and mechanical specifications with active product status and improved performance characteristics (lower ESR, extended lifetime).

Upgrade Substitutes provide higher voltage ratings (80 V vs. 63 V) or extended lifetime ratings while maintaining identical physical dimensions and mounting compatibility. These are suitable for applications where higher voltage margin or reliability is beneficial.

Parametric Equivalents match all critical specifications including ESR characteristics and are functionally interchangeable with identical performance profiles.

Engineering Selection Recommendations

For Direct Replacement with Enhanced Performance: B41505A8108M000 and B41505A8108M007 from EPCOS - TDK Electronics are active products offering lower ESR (149 mOhm vs. 282 mOhm) and extended lifetime (5000 hours vs. 3000 hours) while maintaining identical voltage and capacitance ratings. Both are ROHS3 compliant and REACH unaffected, providing regulatory compliance advantages over the obsolete ECO-S1JA102BA.

For Parametric Equivalence: 381LX102M063H012 from Cornell Dubilier Electronics provides matching ESR characteristics (280 mOhm @ 120Hz) and identical lifetime rating (3000 hours @ 105°C), making it a direct functional equivalent. This part maintains the same physical footprint and is ROHS3 compliant.

For Higher Voltage Margin Applications: 381LX102M080H012, LGU1K102MELZ, and LGY1K102MELZ25 provide 80 V ratings instead of 63 V while maintaining identical physical dimensions and mounting compatibility. These are suitable for applications requiring additional voltage headroom. LGY1K102MELZ25 offers extended 5000-hour lifetime at 105°C.

For Extended Reliability: 63VXG1000MEFC22X25 from Rubycon and ELXG630VSN102MP25S from Chemi-Con both provide 5000-hour lifetime ratings at 105°C with matching 63 V voltage and identical physical specifications, offering improved long-term reliability over the original part.

All recommended substitutes maintain through-hole mounting compatibility, identical lead spacing (10.00 mm), and case dimensions (22.00 mm diameter, 27.00 mm height seated).

Frequently Asked Questions (FAQ)

Q: Can B41505A8108M000 and B41505A8108M007 be used interchangeably with ECO-S1JA102BA? A: Yes. Both parts share identical capacitance (1000 µF), voltage rating (63 V), tolerance (±20%), package type (radial snap-in), lead spacing (10.00 mm), and case dimensions (22.00 mm diameter, 27.00 mm height). Both are active products with ROHS3 compliance and lower ESR than the original part.

Q: What is the difference between 63 V and 80 V rated substitutes? A: The 80 V rated parts (381LX102M080H012, LGU1K102MELZ, LGY1K102MELZ25) provide higher voltage margin for the same physical footprint. They are suitable for applications where additional voltage headroom is beneficial or where circuit design margins require higher rated voltage. All maintain identical capacitance, tolerance, and mechanical dimensions.

Q: Are all substitute parts RoHS compliant? A: All listed substitute parts are RoHS compliant (either ROHS3 or RoHS Compliant status). The original ECO-S1JA102BA is REACH Affected, while all substitutes are REACH Unaffected, providing regulatory compliance advantages.

Q: Does ESR difference affect circuit performance? A: ESR values are provided where specified. B41505A8108M000 and B41505A8108M007 offer lower ESR (149 mOhm @ 100Hz) compared to the original (282 mOhm @ 120Hz), which may improve ripple current handling and thermal performance in high-frequency applications. ELXG630VSN102MP25S provides 120 mOhms impedance. 381LX102M063H012 matches the original ESR at 280 mOhm @ 120Hz for parametric equivalence.

Q: Can I use a substitute with different physical dimensions? A: No. All substitute parts listed maintain identical lead spacing (0.394" / 10.00 mm), case diameter (0.866" / 22.00 mm), and seated height (1.063" / 27.00 mm) to ensure PCB compatibility. 381LX102M063J202 has different dimensions (0.984" diameter, 0.866" height) and is not suitable for direct board replacement.

Q: What is the advantage of 5000-hour lifetime parts over 3000-hour parts? A: Parts rated for 5000 hours at 105°C (B41505A8108M000, B41505A8108M007, 63VXG1000MEFC22X25, LGY1K102MELZ25) provide extended operational life under thermal stress compared to 3000-hour rated parts. This is relevant for applications with continuous operation or elevated ambient temperatures.
