Equivalent & Substitute Parts for UVR1H102MHD1TO

Part Overview

The UVR1H102MHD1TO is a 1000 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line. The part operates across -40°C to 85°C with a rated lifetime of 2000 hours at 85°C and is ROHS3 compliant. Due to its obsolescence status, equivalent and substitute parts from active product lines are necessary for ongoing production and design continuity.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance (1000 µF), voltage rating (50 V), tolerance (±20%), package type (radial can), lead spacing (5.00 mm), case diameter (12.50 mm), height (27.00 mm), mounting type (through hole), and polarization (polar). Parts are grouped into three categories based on their relationship to the main part:

Upgrade Substitutes maintain all electrical and mechanical parameters while offering improved product status (Active vs. Not For New Designs) or enhanced thermal performance (105°C vs. 85°C operating temperature).

Parametric Equivalents match all critical electrical and mechanical specifications but may originate from different manufacturers or series, ensuring functional interchangeability.

Direct Equivalents are from different manufacturers but share identical electrical ratings and physical dimensions, providing alternative sourcing options.

Engineering Selection Recommendations

For Active Product Line Transition: ECA-1HHG102B and EEU-HD1H102B from Panasonic Electronic Components are recommended as primary upgrade substitutes. Both parts are Active status with extended operating temperature range (-55°C to 105°C) and improved thermal lifetime (2000 Hrs @ 105°C). Physical dimensions and electrical ratings are identical to the UVR1H102MHD1TO, ensuring direct board-level compatibility.

For Enhanced Thermal Performance: 860020678026 (Würth Elektronik WCAP-ATG5) provides upgraded thermal specifications with 105°C operating temperature and 2000 Hrs @ 105°C lifetime. Minor dimensional variations (case diameter 13.00 mm vs. 12.50 mm, height 26.50 mm vs. 27.00 mm) require PCB layout verification but remain within typical through-hole tolerance margins.

For Parametric Equivalence: 50PK1000MEFCG412.5X25 (Rubycon PK series) and ECA-1HM102B (Panasonic M-A series) maintain identical electrical and mechanical specifications with Active product status. These parts are suitable for direct substitution in applications where thermal performance requirements match the original -40°C to 85°C specification.

For Same-Manufacturer Alternatives: UFW1H102MHD1TO and UKW1H102MHD1TO from Nichicon provide parametric equivalence within the same manufacturer ecosystem, though both retain Not For New Designs status. These are appropriate for legacy system maintenance where manufacturer continuity is prioritized.

Frequently Asked Questions (FAQ)

Q: Can ECA-1HHG102B be used as a direct replacement for UVR1H102MHD1TO?

A: Yes. Both parts share identical capacitance (1000 µF), voltage rating (50 V), tolerance (±20%), case diameter (12.50 mm), height (27.00 mm), lead spacing (5.00 mm), and through-hole mounting configuration. ECA-1HHG102B is Active status with extended thermal range (-55°C to 105°C vs. -40°C to 85°C), making it a functional upgrade.

Q: What is the difference between 860010678024 and 860020678026 from Würth Elektronik?

A: Both are 1000 µF, 50 V radial capacitors with identical electrical ratings. The primary difference is thermal performance: 860010678024 (WCAP-ATG8) operates to 85°C with 2000 Hrs @ 85°C lifetime, while 860020678026 (WCAP-ATG5) operates to 105°C with 2000 Hrs @ 105°C lifetime. Minor dimensional variations exist (case diameter 13.00 mm vs. 12.50 mm original), requiring PCB verification.

Q: Are there packaging differences between substitute parts?

A: Most substitutes use Cut Tape (CT) packaging identical to the original UVR1H102MHD1TO. The exception is 50PK1000MEFCG412.5X25 (Rubycon), which uses Tape & Box (TB) packaging. This affects handling and storage but does not impact electrical or mechanical compatibility.

Q: Which substitute offers the best thermal performance?

A: ECA-1HHG102B and EEU-HD1H102B both provide 2000 Hrs @ 105°C lifetime with -55°C to 105°C operating range, representing the highest thermal specification among available substitutes. 860020678026 also offers 105°C thermal performance but with slightly different physical dimensions.

Q: Can UFW1H102MHD1TO and UKW1H102MHD1TO be used interchangeably with UVR1H102MHD1TO?

A: Yes, from an electrical and mechanical standpoint. All three Nichicon parts (UVR, UFW, UKW series) share identical 1000 µF, 50 V specifications, case dimensions, and lead spacing. However, UFW and UKW series are designated for audio applications, while UVR is general purpose. All three retain Not For New Designs status.

Q: What should be verified when substituting parts with different case diameters?

A: When substituting 860010678024 or 860020678026 (13.00 mm diameter) for the original 12.50 mm diameter UVR1H102MHD1TO, verify PCB pad spacing and component clearance to adjacent parts. The 0.50 mm diameter increase may affect board layout in space-constrained applications. Height differences (26.50 mm vs. 27.00 mm) are negligible for through-hole mounting.
