Engineering Selection Recommendations

Primary Recommendation for Active Designs: UPA1V102MHD1TO (Nichicon) is the preferred upgrade path. This part maintains identical mechanical footprint and electrical core specifications while offering extended lifetime (5000 Hrs @ 105°C vs. 2000 Hrs @ 85°C) and Active product status. The expanded operating temperature range (-55°C ~ 105°C) provides additional design margin.

Alternative Active Options: EEU-FR1V102B (Panasonic) and 35ZLH1000MEFCG412.5X20 (Rubycon) both carry Active status with superior lifetime ratings (10000 Hrs @ 105°C). These are suitable where extended operational life is required. Both maintain identical mechanical dimensions to the original part.

For Legacy System Maintenance: UFW1V102MHD1TO, UKW1V102MHD1TO, and UVK1V102MHD1TO (Nichicon) provide direct electrical and mechanical equivalence with identical footprints. These are appropriate for repair applications where design changes are not feasible.

Cross-Manufacturer Alternatives: 860020578018 (Würth Elektronik) offers Active status with extended temperature range (-40°C ~ 105°C). Case diameter is 0.512" (13.00 mm) versus 0.492" (12.50 mm) on the original part; height is 0.846" (21.50 mm) versus 0.866" (22.00 mm). These dimensional differences require PCB layout verification before implementation.

ECA-1VHG102B (Panasonic) maintains identical mechanical dimensions with Active status and extended temperature range (-55°C ~ 105°C).

All recommended substitutes carry ROHS3 compliance matching the original part.

Frequently Asked Questions (FAQ)

Q: Can UFW1V102MHD1TO, UKW1V102MHD1TO, and UPA1V102MHD1TO be used interchangeably with UVR1V102MHD1TO?

A: Yes, all three parts meet the mandatory matching parameters: 1000 µF capacitance, 35 V voltage rating, ±20% tolerance, identical lead spacing (0.197" / 5.00 mm), case diameter (0.492" / 12.50 mm), and height (0.866" / 22.00 mm). They are mechanically and electrically compatible. UPA1V102MHD1TO offers enhanced performance with Active product status and extended lifetime.

Q: What is the difference between Cut Tape and Bulk packaging?

A: Cut Tape (CT) packaging provides individual components on carrier tape suitable for automated assembly. Bulk packaging provides loose components. UVR1V102MHD (Bulk) and UVR1V102MHD1TO (Cut Tape) are electrically and mechanically identical; packaging selection depends on assembly process requirements.

Q: Are Würth Elektronik parts 860010578017 and 860020578018 direct replacements?

A: Both parts match the mandatory electrical specifications and lead spacing. However, case diameter is 0.512" (13.00 mm) versus 0.492" (12.50 mm) on the original, and height is 0.846" (21.50 mm) versus 0.866" (22.00 mm). PCB layout verification is required to confirm clearance before substitution.

Q: Why should I choose an Active product status part over Not For New Designs?

A: Active status indicates the manufacturer continues production and provides ongoing technical support. Not For New Designs parts are obsolete in the manufacturer's portfolio. For new designs or long-term system support, Active parts ensure supply chain continuity and access to technical documentation.

Q: What is the significance of lifetime rating differences?

A: Lifetime rating indicates expected operational hours at specified temperature. UVR1V102MHD1TO is rated 2000 Hrs @ 85°C. UPA1V102MHD1TO extends this to 5000 Hrs @ 105°C, and EEU-FR1V102B to 10000 Hrs @ 105°C. Higher ratings indicate greater reliability margin in thermal stress environments.

Q: Can I use EEU-FR1V102B or 35ZLH1000MEFCG412.5X20 in place of UVR1V102MHD1TO?

A: Yes. Both parts maintain identical mechanical footprint (0.492" / 12.50 mm diameter, 0.866" / 22.00 mm height, 0.197" / 5.00 mm lead spacing) and electrical specifications (1000 µF, 35 V, ±20% tolerance). Both carry Active status with superior lifetime ratings, making them suitable upgrades.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed carry ROHS3 compliance matching the original UVR1V102MHD1TO specification.
