Substitute Part Grouping Explanation

Substitute parts for the UES0J102MHM1TO are qualified based on the following electrical and mechanical parameters:

Capacitance: Must be 1000 µF (exact match)
Voltage Rating: Must be equal to or greater than 6.3 V
Tolerance: Must be ±20% or tighter
Polarization: Must be Bi-Polar
Operating Temperature Range: Must cover -40°C ~ 85°C minimum
Lead Spacing: Must be 0.197" (5.00 mm)
Package Type: Must be Radial, Can
Mounting Type: Must be Through Hole

Two substitute parts meet these criteria:

UVP1C102MHD1TO (Nichicon) – Upgrade with higher voltage rating (16 V) and extended lifetime (2000 Hrs @ 85°C)
ECE-A1CN102UB (Panasonic Electronic Components) – Upgrade with higher voltage rating (16 V), extended lifetime (2000 Hrs @ 85°C), and Active product status

Engineering Selection Recommendations

Both substitute parts are electrically and mechanically compatible with the UES0J102MHM1TO. Selection between them should be based on the following factors:

UVP1C102MHD1TO (Nichicon)

Maintains manufacturer continuity with the original part
Provides higher voltage rating (16 V vs. 6.3 V) for improved design margin
Doubles the operational lifetime (2000 Hrs @ 85°C vs. 1000 Hrs @ 85°C)
Product status remains Not For New Designs
ROHS3 Compliant; REACH Affected

ECE-A1CN102UB (Panasonic Electronic Components)

Offers Active product status, ensuring long-term availability and supply chain stability
Provides higher voltage rating (16 V vs. 6.3 V) for improved design margin
Doubles the operational lifetime (2000 Hrs @ 85°C vs. 1000 Hrs @ 85°C)
Introduces manufacturer change from Nichicon to Panasonic
ROHS3 Compliant; REACH Unaffected

For legacy system support where manufacturer consistency is critical, UVP1C102MHD1TO is appropriate. For new production runs or long-term supply assurance, ECE-A1CN102UB is recommended due to its Active product status.

Frequently Asked Questions (FAQ)

Q: Can UVP1C102MHD1TO or ECE-A1CN102UB be used as direct replacements for UES0J102MHM1TO?

A: Yes. Both parts match the required electrical specifications (1000 µF capacitance, ±20% tolerance, bi-polar configuration) and mechanical parameters (lead spacing, package type, mounting configuration). The higher voltage ratings (16 V) provide additional design margin and are electrically compatible in circuits designed for 6.3 V operation.

Q: What is the impact of the increased voltage rating on circuit performance?

A: A higher voltage rating does not negatively affect circuit performance. The capacitor will operate safely in applications designed for 6.3 V. The increased voltage rating provides additional safety margin and typically results in lower ESR and improved ripple current handling.

Q: Are there physical fit concerns when substituting these parts?

A: The substitute parts have slightly increased maximum seated height (1.063" vs. 1.043"), a difference of 0.020" (0.50 mm). Verify that PCB layout and enclosure clearances accommodate this minor dimensional increase.

Q: What is the difference between "Not For New Designs" and "Active" product status?

A: "Not For New Designs" indicates the manufacturer has superseded the part and does not recommend it for new applications, though existing inventory may remain available. "Active" status indicates the manufacturer actively produces and supports the part for both new and existing applications, ensuring long-term availability.

Q: Are all three parts RoHS3 compliant?

A: Yes. UES0J102MHM1TO, UVP1C102MHD1TO, and ECE-A1CN102UB are all ROHS3 Compliant.

Q: What is the difference in REACH status between the substitute parts?

A: UVP1C102MHD1TO is REACH Affected, while ECE-A1CN102UB is REACH Unaffected. For applications subject to REACH regulations, ECE-A1CN102UB may be the preferred choice.
