Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Capacitance: 2700 µF (exact match required)
Voltage Rating: 63 V (exact match required)
Tolerance: ±20% (exact match required)
Package / Case: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)

Substitute parts are grouped by relationship type: Direct equivalents maintain identical electrical and mechanical specifications; upgrades provide enhanced performance characteristics such as extended lifetime; similar parts meet core electrical requirements but may vary in physical dimensions or secondary performance metrics; parametric equivalents satisfy primary electrical parameters with minor variations in ripple current or ESR specifications.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance, ensuring regulatory alignment for new designs and production environments. The ECO-S1JA272DA is obsolete; direct replacement candidates include 381LX272M063K012, LGU1J272MELB, and LGY1J272MELB25, which maintain identical electrical and mechanical specifications.

For applications requiring extended operational lifetime, LGY1J272MELB25 provides 5000 hours at 105°C compared to the standard 3000 hours, supporting designs with higher reliability requirements. This upgrade maintains identical physical dimensions and electrical parameters.

Parts with dimensional variations—such as 381LX272M063H042, 381LX272M063J032, SLP272M063A7P3, and SLP272M063C5P3—require PCB layout verification to confirm mechanical fit within the available mounting space. These alternatives satisfy core electrical specifications but differ in can diameter and height.

B41252C8278M offers equivalent physical dimensions to the original part but provides reduced lifetime (2000 hours at 105°C), making it suitable only for applications with lower thermal stress or shorter service life expectations.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different physical dimensions?

A: Physical dimensions must be verified against PCB layout and mechanical constraints. Parts with different can diameter or height may not fit existing mounting locations. Confirm available space before selection.

Q: What is the significance of ESR (Equivalent Series Resistance)?

A: ESR affects ripple current handling and thermal performance. The original part specifies 104 mOhm at 120 Hz. Substitute parts with higher ESR values may generate additional heat under high ripple current conditions. Verify thermal requirements for your application.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original ECO-S1JA272DA does not specify RoHS status. Confirm compliance requirements for your end application and regulatory jurisdiction.

Q: What is the difference between direct equivalents and similar parts?

A: Direct equivalents maintain identical electrical and mechanical specifications. Similar parts meet core electrical requirements (capacitance, voltage, tolerance, lifetime) but may vary in physical dimensions, ESR, or ripple current ratings. Verify all parameters against design requirements.

Q: Should I select the upgrade part with 5000-hour lifetime?

A: The LGY1J272MELB25 upgrade provides extended lifetime (5000 hours at 105°C) with identical physical dimensions and electrical parameters. Selection depends on application thermal stress and required service life. No design changes are necessary for this upgrade.

Q: How do I verify lead spacing compatibility?

A: All listed parts maintain 0.394" (10.00 mm) lead spacing, matching the original ECO-S1JA272DA. This parameter is fixed across all substitutes and requires no verification.

Q: What ripple current rating should I use for thermal calculations?

A: Use the ripple current specification at the operating frequency closest to your application. The original part specifies 2.2 A at 120 Hz and 2.53 A at 100 kHz. Substitute parts provide similar or equivalent ripple current ratings at comparable frequencies.
