ECA-2WHG010BJ Equivalent & Substitute Parts

Part Overview

The ECA-2WHG010BJ is a 1 µF, 450 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This component is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring polar capacitance in through-hole configurations. The part is currently active in production with ROHS3 compliance and REACH unaffected status.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for components with different thermal ratings or physical dimensions while maintaining electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECA-2WHG010BJ is determined by the following core parameters:

• Electrical Parameters: Capacitance (1 µF), voltage rating (450 V), and tolerance (±20%) must match exactly
• Mechanical Compatibility: Through-hole mounting and radial, can package format are required for direct board-level substitution
• Environmental Specifications: Operating temperature range (-25°C to 105°C) and polarization (polar) must be maintained
• Compliance: ROHS3 compliance and REACH unaffected status ensure regulatory alignment

Substitute parts are grouped into two categories:

1. Direct Equivalents: Identical electrical and mechanical specifications with matching or superior thermal ratings
2. Compatible Alternatives: Matching electrical specifications with variations in physical dimensions, thermal ratings, or product status that may require design review

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: ECA-2WHG010

The ECA-2WHG010 from Panasonic is the direct equivalent to ECA-2WHG010BJ with identical electrical specifications, thermal rating, and physical dimensions. Both parts are active in production status and ROHS3 compliant. This part is suitable for direct substitution without design modification.

Secondary Recommendations for Active Parts:

EKMG451ELL1R0MJC5S (Chemi-Con) maintains electrical compatibility with identical capacitance, voltage, and tolerance specifications. However, this part features larger physical dimensions (0.394" diameter, 0.551" height versus 0.315" diameter, 0.492" height) and a reduced thermal rating (1000 hours at 105°C versus 2000 hours). This part is suitable only when PCB layout accommodates the larger footprint and the reduced thermal rating meets application requirements.

Not Recommended for New Designs:

UPJ2W010MPD, UPS2W010MPD, UPW2W010MPD, and UVZ2W010MPD are all obsolete or marked "Not For New Designs" and should not be selected for new product development. These parts may be considered only for legacy system maintenance or repair where original part specifications are mandatory.

Frequently Asked Questions (FAQ)

Q: Can I use ECA-2WHG010 as a direct replacement for ECA-2WHG010BJ?

A: Yes. Both parts are manufactured by Panasonic with identical electrical specifications (1 µF, 450 V, ±20%), thermal rating (2000 hours at 105°C), and physical dimensions. The primary difference is packaging format (tape and reel versus bulk). Direct substitution is possible without design changes.

Q: What is the difference between the Panasonic and Chemi-Con alternatives?

A: The Chemi-Con EKMG451ELL1R0MJC5S matches the electrical specifications but differs in three ways: thermal rating is reduced to 1000 hours at 105°C (versus 2000 hours), physical dimensions are larger (0.394" diameter and 0.551" height versus 0.315" diameter and 0.492" height), and lead spacing is 0.197" (5.00mm) versus 0.138" (4.60mm). Substitution requires verification that the PCB layout accommodates the larger footprint and that the reduced thermal rating is acceptable for the application.

Q: Why are the Nichicon parts marked as obsolete?

A: UPJ2W010MPD, UPS2W010MPD, UPW2W010MPD, and UVZ2W010MPD are obsolete or not recommended for new designs. These designations indicate that the manufacturer has discontinued active production or recommends against their use in new product development. These parts should be used only for maintenance of existing systems.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference, including the main part ECA-2WHG010BJ and all substitutes, are ROHS3 compliant and REACH unaffected. Regulatory compliance is maintained across all options.

Q: What happens if I use a substitute with a different thermal rating?

A: Thermal rating (lifetime at 105°C) affects component reliability under sustained elevated temperature operation. A part with a lower thermal rating (such as 1000 hours versus 2000 hours) will have a shorter operational life in high-temperature environments. Selection must be based on the actual operating temperature profile and required system lifetime for the application.

Q: Can I use parts with larger physical dimensions as substitutes?

A: Physical dimensions determine PCB footprint compatibility. Parts with larger diameters or heights may not fit existing PCB layouts without design modification. Verify that the substitute part's dimensions (diameter, height, and lead spacing) are compatible with the available PCB space before selection.
