Substitute Part Grouping Explanation

Substitution for the UVR2W010MPD1TD is determined by strict equivalence in the following parameters:

Capacitance: 1 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.138" (4.60 mm) (exact match required)
Case Diameter: 0.315" (8.00 mm) (exact match required)

Two substitute parts meet these criteria:

ECA-2WM010BJ (Panasonic) — Direct equivalent with identical electrical and mechanical specifications. Active product status.
ECA-2WHG010BJ (Panasonic) — Upgrade option with enhanced temperature rating (2000 Hrs @ 105°C vs. 2000 Hrs @ 85°C) and extended operating temperature range (-25°C ~ 105°C vs. -25°C ~ 85°C). Active product status.

Engineering Selection Recommendations

ECA-2WM010BJ is the direct functional equivalent to UVR2W010MPD1TD. Both parts share identical electrical ratings, mechanical dimensions, and thermal specifications. This part is suitable for direct replacement in applications where the original component is unavailable. The part carries Active product status and maintains full ROHS3 and REACH compliance.

ECA-2WHG010BJ is an upgrade option that maintains all core electrical and mechanical compatibility while providing enhanced thermal performance. The extended operating temperature range (-25°C ~ 105°C) and higher temperature lifetime rating (2000 Hrs @ 105°C) make this part suitable for applications requiring improved thermal margin or operation in elevated temperature environments. This part also carries Active product status with full regulatory compliance.

Both substitute parts are through-hole radial capacitors with identical lead spacing and case diameter, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can ECA-2WM010BJ be used as a direct replacement for UVR2W010MPD1TD?

A: Yes. Both parts have identical capacitance (1 µF), voltage rating (450 V), tolerance (±20%), operating temperature range (-25°C ~ 85°C), and mechanical dimensions. Lead spacing and case diameter are identical, allowing direct PCB substitution without layout changes.

Q: What is the difference between ECA-2WM010BJ and ECA-2WHG010BJ?

A: Both parts are electrically and mechanically equivalent to the original UVR2W010MPD1TD. The primary difference is thermal performance: ECA-2WHG010BJ has an extended operating temperature range (-25°C ~ 105°C vs. -25°C ~ 85°C) and a higher temperature lifetime rating (2000 Hrs @ 105°C vs. 2000 Hrs @ 85°C). ECA-2WHG010BJ is suitable for applications requiring enhanced thermal capability.

Q: Are there any physical dimension differences between these parts?

A: The case diameter (0.315" / 8.00 mm) and lead spacing (0.138" / 4.60 mm) are identical across all three parts. The seated height differs slightly: UVR2W010MPD1TD is 0.512" (13.00 mm), while both Panasonic substitutes are 0.492" (12.50 mm). This minor difference does not affect PCB compatibility for standard through-hole applications.

Q: Do these parts meet current regulatory requirements?

A: Yes. Both ECA-2WM010BJ and ECA-2WHG010BJ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The original UVR2W010MPD1TD also meets these requirements.

Q: Which substitute should I select for a new design?

A: Both substitute parts carry Active product status. For new designs, either part is acceptable. ECA-2WHG010BJ is recommended if the application operates at elevated temperatures or requires extended thermal margin.
