Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPB2W100MHD1TO is determined by the following critical parameters:

• Capacitance Value: Must be 10 µF (no tolerance variation acceptable)
• Voltage Rating: Minimum 450 V (equal or higher ratings are acceptable)
• Tolerance: ±20% (matching specification)
• Polarization: Polar (required for electrolytic type)
• Package Configuration: Radial, can format with 0.197" (5.00 mm) lead spacing
• Physical Footprint: 0.492" diameter, 0.846" maximum height
• Mounting Method: Through hole only

Substitute parts are classified into two categories:

1. Direct Manufacturer Equivalents: Nichicon parts from successor series (UCA, UCY) with identical or superior electrical performance
2. Parametric Equivalents: Alternative manufacturer components (Chinsan/Elite) meeting all critical electrical and mechanical specifications

Engineering Selection Recommendations

UCA2W100MHD1TO (Nichicon Direct Equivalent)

This part maintains identical electrical specifications to the UPB2W100MHD1TO while offering extended lifetime (12000 Hrs @ 105°C versus 5000 Hrs). The UCA series represents Nichicon's direct successor to the UPB line. Product status is "Not For New Designs," indicating this is a transitional option suitable for legacy system maintenance and repair applications where Nichicon continuity is required.

UCY2H100MHD (Nichicon Active Alternative)

The UCY2H100MHD provides the highest voltage rating (500 V) among all options, exceeding the original 450 V specification. This part is classified as Active, ensuring long-term availability and supply chain stability. The extended operating temperature range (-40°C to 105°C) provides additional environmental margin. This option is preferred for new designs and applications requiring extended component lifecycle support.

LL2W100MP51220ER (Chinsan/Elite Parametric Equivalent)

This alternative manufacturer component meets all critical electrical and mechanical specifications. The LL series demonstrates superior ripple current handling (315 mA @ 120 Hz and 504 mA @ 100 kHz) compared to the original part, with equivalent lifetime rating (5000 Hrs @ 105°C). This option is suitable for cost-sensitive applications where multi-source qualification is acceptable. Product status is Active with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can UCY2H100MHD replace UPB2W100MHD1TO in existing circuits?

A: Yes. The UCY2H100MHD meets all critical substitution parameters: identical 10 µF capacitance, ±20% tolerance, radial can package with 5.00 mm lead spacing, and through-hole mounting. The 500 V rating exceeds the original 450 V requirement, providing voltage margin. Operating temperature range is expanded to -40°C to 105°C.

Q: What is the difference between direct manufacturer equivalents and parametric equivalents?

A: Direct manufacturer equivalents (UCA2W100MHD1TO, UCY2H100MHD) are Nichicon products from successor series, ensuring design continuity and manufacturer support. Parametric equivalents (LL2W100MP51220ER) are alternative manufacturer components meeting identical electrical and mechanical specifications but from different manufacturers. Both categories are electrically compatible within the specified parameters.

Q: Does the extended lifetime of UCA2W100MHD1TO affect circuit performance?

A: No. Extended lifetime (12000 Hrs @ 105°C versus 5000 Hrs) indicates improved internal construction and materials but does not alter electrical performance. Capacitance, voltage rating, tolerance, and ripple current specifications remain compatible with the original UPB2W100MHD1TO design.

Q: Are there packaging differences between substitute parts?

A: UCA2W100MHD1TO is supplied in Cut Tape (CT) packaging. UCY2H100MHD is supplied in Bulk packaging. LL2W100MP51220ER is supplied in Cut Tape (CT) packaging. All three maintain identical through-hole radial can format with 5.00 mm lead spacing, ensuring PCB footprint compatibility.

Q: Which substitute part should be selected for new designs?

A: UCY2H100MHD is recommended for new designs. This part carries Active product status, ensuring long-term availability and supply chain support. The 500 V rating provides voltage margin, and the extended operating temperature range (-40°C to 105°C) offers additional environmental protection compared to the original -25°C to 105°C specification.

Q: Is the LL2W100MP51220ER suitable for high-ripple-current applications?

A: Yes. The LL2W100MP51220ER demonstrates superior ripple current performance (315 mA @ 120 Hz and 504 mA @ 100 kHz) compared to the original UPB2W100MHD1TO (150 mA @ 120 Hz and 300 mA @ 100 kHz). This characteristic makes it suitable for applications with elevated ripple current demands while maintaining the same 5000 Hrs @ 105°C lifetime rating.
