EET-HC2G561LA Equivalent & Substitute Parts

Part Overview

The Panasonic EET-HC2G561LA is a 560 µF, 400 V aluminum electrolytic capacitor in radial, can snap-in package format, rated for general-purpose applications. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical equivalence across capacitance, voltage rating, tolerance, and mechanical compatibility while meeting current product availability and compliance requirements.

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict electrical and mechanical compatibility criteria. All substitute parts maintain the core specifications: 560 µF capacitance, 400 V voltage rating, ±20% tolerance, and radial snap-in package with 10.00 mm lead spacing and 35.00 mm diameter. Substitution validity is determined by:

Identical capacitance and voltage rating
Matching tolerance specification
Compatible package geometry (lead spacing, diameter, mounting type)
Operating temperature range that meets or exceeds the original specification
Polarization type (polar)

Height variation is permitted within the snap-in package design, as the mechanical interface is determined by lead spacing and diameter. Lifetime at temperature and ESR characteristics are performance differentiators but do not prevent substitution when electrical and mechanical parameters align.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically compatible with the EET-HC2G561LA. Selection should be based on product status and compliance requirements:

Primary Recommendation: B43644B9567M000 (EPCOS - TDK Electronics) provides the closest electrical match with identical height (1.654" / 42.00 mm), superior lifetime rating (5000 Hrs @ 105°C versus 2000 Hrs), and lower ESR (170 mOhm @ 100 Hz). This part is active, RoHS3 compliant, and REACH unaffected.

Alternative Options: Rubycon 400MXG560MEFCSN35X40 offers extended lifetime (3000 Hrs @ 105°C) with matching height geometry. EPCOS B43508 series variants (B43508B9567M60, B43508B9567M67, B43508B9567M7, B43508B9567M80, B43508B9567M87) provide 3000-hour lifetime ratings with active product status and RoHS3 compliance, though with slightly increased height (1.661" / 42.20 mm).

Compact Alternative: For applications with height constraints, B43640B9567M000 or Rubycon 400MXH560MEFC35X35 / 400MXH560MEFCSN35X35 reduce height to 1.457" (37.00 mm) while maintaining 2000-hour lifetime and full electrical compatibility.

All substitute parts carry RoHS3 compliance and REACH unaffected or REACH affected status consistent with the original component classification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the EET-HC2G561LA with any of these parts directly?

A: Yes. All listed parts maintain 560 µF capacitance, 400 V voltage rating, ±20% tolerance, and radial snap-in package geometry with 10.00 mm lead spacing and 35.00 mm diameter. Mechanical compatibility is ensured across all substitutes.

Q: Does height variation affect compatibility?

A: Height variation does not affect electrical or mechanical compatibility in snap-in package designs. The snap-in interface is determined by lead spacing (10.00 mm) and can diameter (35.00 mm). Height differences range from 1.457" to 1.661" across all substitutes and the original part. Verify available board space if height is a design constraint.

Q: What is the difference between the Rubycon and EPCOS options?

A: Both manufacturers provide equivalent electrical performance. Rubycon 400MXG560MEFCSN35X40 offers 3000-hour lifetime with matching original height (42.00 mm). EPCOS B43644B9567M000 provides superior 5000-hour lifetime with lower ESR (170 mOhm). EPCOS B43508 series variants deliver 3000-hour lifetime with slightly increased height (42.20 mm). Selection depends on lifetime requirements and available board space.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance certification. The original EET-HC2G561LA is REACH affected; substitute parts are either REACH unaffected (EPCOS, Rubycon) or REACH affected (Panasonic). Verify REACH compliance requirements for your specific application and region.

Q: What does ESR mean and why does it vary?

A: ESR (Equivalent Series Resistance) is measured at 100 Hz or 120 Hz and represents internal resistance. Lower ESR indicates better high-frequency performance and reduced heat generation. The original part specifies 326 mOhm @ 120 Hz. Substitutes range from 170 to 220 mOhm @ 100 Hz, representing equivalent or superior performance. ESR is not a substitution barrier when other parameters align.

Q: Can I use a substitute with longer lifetime (5000 Hrs) in place of the original (2000 Hrs)?

A: Yes. Extended lifetime is a performance enhancement and does not create compatibility issues. B43644B9567M000 with 5000-hour rating is a direct upgrade for the original 2000-hour specification.
