Package Type: Radial, Can
Lead Spacing: 0.197" (5.00 mm)
Size / Dimension: 0.492" Dia (12.50 mm)
Mounting Type: Through Hole
RoHS Status: ROHS3 Compliant

Secondary Considerations (Allowable Variations):

Height - Seated (Max): ±0.020" tolerance acceptable

Engineering Selection Recommendations

Direct Mechanical Equivalents (Identical Footprint):

688CKS6R3M, ESMG6R3ELL682MK25S, and ESMQ6R3ELL682MK25S are direct substitutes with identical lead spacing (0.197"), diameter (0.492"), and height within 0.020" of the original. All are ROHS3 compliant and active products. These parts maintain the same electrical specifications and thermal performance as UVR0J682MHD.

Enhanced Thermal Performance Options:

6.3YXJ6800M12.5X25, ECA-0JHG682, and ECA-0JHG682B offer extended lifetime ratings (8000 Hrs @ 105°C and 2000 Hrs @ 105°C respectively) with identical physical footprints. These are suitable for applications requiring improved reliability or operation at elevated temperatures. All maintain ROHS3 compliance and active product status.

Higher Voltage Rating Option:

10PK6800MEFC12.5X25 provides 10 V rating while maintaining identical physical dimensions and lead spacing. This upgrade is applicable where circuit voltage margins require additional headroom, with no mechanical redesign necessary.

Non-Compatible Substitute:

URS0J682MHD, while electrically equivalent, features different lead spacing (0.295" vs. 0.197") and larger physical dimensions. This part requires PCB layout modification and is not a direct drop-in replacement.

Frequently Asked Questions (FAQ)

Q: Can URS0J682MHD replace UVR0J682MHD directly on the PCB?

A: No. URS0J682MHD has lead spacing of 0.295" (7.50 mm) compared to UVR0J682MHD's 0.197" (5.00 mm), and larger overall dimensions. PCB layout modification is required.

Q: Are 688CKS6R3M and ESMG6R3ELL682MK25S interchangeable with UVR0J682MHD?

A: Yes. Both parts match the critical parameters: 6800 µF capacitance, 6.3 V rating, ±20% tolerance, 0.197" lead spacing, 0.492" diameter, and height within acceptable tolerance. All are ROHS3 compliant and active products.

Q: What is the advantage of 6.3YXJ6800M12.5X25 over the original UVR0J682MHD?

A: 6.3YXJ6800M12.5X25 provides 8000 Hrs @ 105°C lifetime versus 2000 Hrs @ 85°C for UVR0J682MHD, with extended operating temperature range (-40°C ~ 105°C). Physical footprint is identical, enabling direct substitution with improved reliability.

Q: Can 10PK6800MEFC12.5X25 be used in place of UVR0J682MHD?

A: Yes, mechanically and electrically. 10PK6800MEFC12.5X25 has 10 V rating instead of 6.3 V, which is acceptable in circuits designed for 6.3 V operation. The higher voltage rating provides additional safety margin with no physical redesign required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original UVR0J682MHD specification.

Q: What is the difference between ECA-0JHG682 and ECA-0JHG682B?

A: Both parts are electrically and mechanically identical with 6800 µF capacitance, 6.3 V rating, and 2000 Hrs @ 105°C lifetime. The "B" designation indicates a variant within the same product line. Both are suitable substitutes with identical performance characteristics.
