Substitute Part Grouping Explanation

Substitution of the UVK2D470MHD1TO is determined by the following critical parameters:

Electrical Parameters:

Capacitance: 47 µF (exact match required)
Voltage Rating: 200 V minimum (equal or higher voltage ratings are acceptable)
Tolerance: ±20% (standard tolerance for this category)
Polarization: Polar (radial aluminum electrolytic)

Mechanical Parameters:

Lead Spacing: 0.197" (5.00 mm) — must match for PCB compatibility
Package Type: Radial, Can — form factor must be identical
Diameter: 0.492" (12.50 mm) — physical fit requirement
Mounting Type: Through Hole — connection method must match

Performance Parameters:

Operating Temperature Range: -40°C ~ 85°C minimum (equal or wider range acceptable)
Ripple Current Ratings: Must meet or exceed application requirements

Substitute parts are grouped into three categories:

Direct Equivalents (UCY Series): Same electrical and mechanical specifications as the main part, with improved lifetime ratings (12000 Hrs @ 105°C) and higher operating temperature capability (-40°C ~ 105°C). These are pin-compatible direct replacements with enhanced reliability.

Upgrade Options (UCS Series): Same electrical and mechanical specifications with intermediate lifetime (10000 Hrs @ 105°C) and extended operating temperature range (-40°C ~ 105°C). These represent a performance upgrade path for active designs.

Parametric Equivalents (UVR Series): Identical electrical and mechanical specifications to the main part with matching lifetime and temperature ratings. These are legacy-series alternatives with equivalent performance characteristics.

Voltage-Rated Variants: Parts with 250 V ratings (UCY2E470MHD3TO, UCS2E470MHD1TO, UVK2E470MHD1TO) are suitable for applications where higher voltage margin is required, maintaining all other mechanical and electrical compatibility.

Engineering Selection Recommendations

For Direct Replacement (Maintenance & Repair): Select UCY2D470MHD3TO or UCS2D470MHD1TO for immediate substitution. Both maintain the 200 V rating and 47 µF capacitance with identical mechanical fit. The UCY series offers superior lifetime (12000 Hrs @ 105°C) and extended operating temperature range. The UCS series provides a balance between performance upgrade and cost. Both are Active status products with full availability.

For Voltage Margin Applications: If the circuit design permits, UCY2E470MHD3TO or UCS2E470MHD1TO provide 250 V rating while maintaining all mechanical compatibility. These are suitable for applications requiring higher voltage headroom or operating in elevated ambient conditions.

For Legacy System Compatibility: UVR2D470MHD1TO provides parametric equivalence with identical lifetime and temperature characteristics to the original UVK2D470MHD1TO. This option is appropriate when design validation has been completed on the original specification and performance matching is critical.

Compliance Considerations: All substitute parts maintain ROHS3 compliance. UCY series parts carry REACH Affected status; UCS and UVR series parts are REACH Unaffected. Verify compliance requirements for your specific application and regulatory jurisdiction before final selection.

Frequently Asked Questions (FAQ)

Q: Can I use a 250 V rated part in place of a 200 V part? A: Yes. Higher voltage ratings provide additional safety margin and are electrically compatible in circuits designed for lower voltages. The 250 V variants (UCY2E470MHD3TO, UCS2E470MHD1TO) are direct mechanical substitutes with identical physical dimensions and lead spacing.

Q: What is the difference between UCY and UCS series substitutes? A: Both are Active status products with extended operating temperature range (-40°C ~ 105°C). The UCY series offers longer lifetime (12000 Hrs @ 105°C) compared to UCS (10000 Hrs @ 105°C). The UCS series carries REACH Unaffected status, while UCY is REACH Affected. Physical dimensions differ slightly in height (UCY: 0.846", UCS: 0.846" vs. original UVK: 0.866"), but both fit standard through-hole PCB layouts.

Q: Is the UVR2D470MHD1TO a true equivalent? A: Yes. The UVR2D470MHD1TO is a parametric equivalent with identical electrical specifications (47 µF, 200 V, ±20% tolerance), lifetime (2000 Hrs @ 85°C), and operating temperature range (-40°C ~ 85°C). It is mechanically compatible with identical lead spacing, diameter, and height. It is classified as "Not For New Designs" status, similar to the original part.

Q: Will these parts fit my existing PCB without modification? A: All substitute parts maintain the critical mechanical parameters: 0.197" (5.00 mm) lead spacing, 0.492" (12.50 mm) diameter, and Through Hole mounting type. The height varies slightly (0.846" for UCY/UCS vs. 0.866" for UVK/UVR), but this difference is within standard PCB clearance tolerances and does not require layout modification.

Q: What is the ripple current capability of the substitute parts? A: UCY and UCS series parts provide significantly higher ripple current ratings (490 mA @ 120 Hz, 980 mA @ 100 kHz) compared to the original UVK series (270 mA @ 120 Hz, 432 mA @ 10 kHz). This enhanced capability supports higher current applications and improved thermal performance.

Q: Should I choose an Active status part over a "Not For New Designs" part? A: For new designs and long-term production, select Active status parts (UCY or UCS series). For maintenance of existing equipment where the original specification is validated, either Active or "Not For New Designs" equivalents are acceptable. Active status parts offer extended availability and improved performance characteristics.
