ECA-2WHG010B Equivalent & Substitute Parts

Part Overview

The ECA-2WHG010B is a 1 µF, 450 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This component is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring polar capacitive energy storage. The part is currently active in production with ROHS3 compliance and is available in cut tape packaging.

Equivalent and substitute parts are necessary when the original ECA-2WHG010B becomes unavailable, when alternative packaging formats are required, or when design specifications allow for components with different thermal ratings or dimensional characteristics while maintaining electrical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ECA-2WHG010B is determined by the following mandatory parameters:

Capacitance: Must be 1 µF
Voltage Rating: Must be 450 V or higher
Polarization: Must be Polar
Package Type: Must be Radial, Can
Mounting Type: Must be Through Hole
Operating Temperature Range: Must support -25°C to 105°C minimum

Engineering Selection Recommendations

Primary Recommendation: ECA-2WHG010 (Panasonic)

The ECA-2WHG010 is the direct equivalent to ECA-2WHG010B, differing only in packaging format (bulk versus cut tape). Both parts are manufactured by Panasonic, share identical electrical specifications, and maintain active product status with ROHS3 compliance. This part is suitable for direct substitution when cut tape packaging is not required.

Secondary Recommendation: UPS2W010MPD (Nichicon)

The UPS2W010MPD matches the thermal rating of the ECA-2WHG010B (2000 hours at 105°C) and maintains all mandatory electrical parameters. However, this part is marked as obsolete and features larger physical dimensions (0.394" diameter, 0.551" height). Selection of this part is appropriate only when inventory constraints exist and PCB layout accommodates the increased size.

Alternative for Extended Lifetime Applications: UPJ2W010MPD or UPW2W010MPD (Nichicon)

Both UPJ2W010MPD and UPW2W010MPD offer extended thermal ratings (5000 hours at 105°C), providing superior reliability in high-temperature environments. Both parts are obsolete. UPW2W010MPD maintains the same height as the original part (0.492") while UPJ2W010MPD is taller (0.650"). These parts are suitable only when extended lifetime is a design requirement and obsolete component sourcing is feasible.

Not Recommended for New Designs: UVZ2W010MPD (Nichicon)

The UVZ2W010MPD is designated "Not For New Designs" and features a reduced thermal rating (1000 hours at 105°C). This part should be avoided in new designs despite meeting mandatory electrical parameters.

Dimensional Consideration: EKMG451ELL1R0MJC5S (Chemi-Con)

The EKMG451ELL1R0MJC5S is manufactured by Chemi-Con and meets all mandatory electrical specifications. However, it features the largest physical dimensions (0.394" diameter, 0.551" height) and the lowest thermal rating (1000 hours at 105°C). This part is suitable only when PCB layout permits increased size and reduced thermal performance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can I substitute ECA-2WHG010B with ECA-2WHG010?

A: Yes. Both parts are identical in electrical specifications and thermal rating. The only difference is packaging format. ECA-2WHG010B is supplied in cut tape while ECA-2WHG010 is supplied in bulk. Electrical substitution is direct.

Q: What is the difference between lead spacing of 0.138" and 0.197"?

A: Lead spacing determines the distance between the two radial leads on the capacitor. A 0.138" spacing (4.60mm) is narrower than 0.197" (5.00mm). PCB design must accommodate the specific lead spacing of the selected part. Parts with different lead spacing are not interchangeable on the same PCB without layout modification.

Q: Can I use a substitute part with a higher voltage rating?

A: Yes. A capacitor rated for 450 V or higher can be substituted for a 450 V application. Higher voltage ratings provide additional safety margin. However, physical size typically increases with voltage rating, which may affect PCB layout.

Q: Why are some substitute parts marked as obsolete?

A: Obsolete parts are no longer manufactured by the supplier but may remain available through inventory channels. Obsolete parts should be used only when active alternatives are unavailable or when specific performance characteristics (such as extended thermal lifetime) justify the sourcing challenge.

Q: Does thermal lifetime rating affect substitutability?

A: Thermal lifetime rating does not prevent substitution but indicates expected operational life at maximum temperature. A part with 2000 hours at 105°C can be substituted with a part rated for 5000 hours at 105°C without electrical compatibility issues. However, substituting a 2000-hour part for a 5000-hour requirement may result in premature failure.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed maintain ROHS3 compliance, ensuring compatibility with environmental and regulatory requirements.

Q: What happens if I use a substitute part with different physical dimensions?

A: Physical dimensions affect PCB layout and mechanical fit. A substitute part with larger diameter or height may not fit the original PCB footprint. Verify that PCB layout accommodates the selected part's dimensions before implementation.
