Substitute Part Grouping Explanation

Substitution for the UPJ2W4R7MHD1TO is determined by strict equivalence across the following electrical and mechanical parameters:

Capacitance value: 4.7 µF (exact match required)
Voltage rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead spacing: 0.197" (5.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial, Can (exact match required)

Two substitute parts meet these criteria. The UPM2W4R7MHD1TO is a direct manufacturer equivalent from Nichicon with identical electrical specifications. The LL2W4R7MP51016R from Chinsan (Elite) is a similar alternative that maintains all critical electrical and mechanical parameters while offering enhanced ripple current performance.

Engineering Selection Recommendations

The UPM2W4R7MHD1TO is the preferred direct substitute, offering identical electrical specifications and mechanical dimensions from the original manufacturer. This part carries AEC-Q200 automotive qualification and maintains full ROHS3 compliance, making it suitable for applications requiring manufacturer continuity and established reliability data.

The LL2W4R7MP51016R is an active alternative from Chinsan (Elite) that meets all critical electrical and mechanical substitution criteria. This part offers superior ripple current performance and a more compact physical footprint. It is ROHS3 compliant and carries MSL 1 rating. Selection of this alternative is appropriate for applications where enhanced ripple current handling or space constraints are design considerations.

Frequently Asked Questions (FAQ)

Q: Can the LL2W4R7MP51016R be used as a direct drop-in replacement for the UPJ2W4R7MHD1TO?

A: The LL2W4R7MP51016R maintains electrical equivalence across capacitance, voltage rating, tolerance, and operating temperature range. However, physical dimensions differ: the LL series has a smaller diameter (0.394" vs 0.492") and reduced height (0.689" vs 1.043"). PCB layout verification is required to confirm mechanical fit before substitution.

Q: What is the difference between the UPM2W4R7MHD1TO and LL2W4R7MP51016R?

A: Both parts are electrically equivalent at the specified capacitance, voltage, and tolerance levels. The UPM2W4R7MHD1TO maintains identical physical dimensions to the original part and carries automotive qualification. The LL2W4
