Substitute Part Grouping Explanation

Substitution for the URZ1E221MPD is determined by strict adherence to the following electrical and mechanical parameters:

Core Electrical Requirements:

Capacitance: 220 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 25 V minimum (equal or higher voltage rating acceptable)
Operating Temperature Range: -55°C ~ 105°C (must encompass or match)
Polarization: Polar (exact match required)

Mechanical Requirements:

Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00mm) preferred for direct PCB compatibility
Physical Dimensions: Compatible with 0.394" Dia (10.00mm) footprint

Performance Considerations:

Lifetime @ Temperature: 1000 Hrs @ 105°C minimum (extended lifetime acceptable)
Ripple Current Ratings: Must meet or exceed application requirements

Substitute parts are grouped into two categories: direct mechanical replacements (identical lead spacing and dimensions) and functional equivalents (same electrical specifications with different physical form factors).

Engineering Selection Recommendations

Direct Mechanical Replacement (Preferred for PCB Retrofit):

UPJ1E221MPD6 and UPM1E221MPD6 are the primary candidates for direct mechanical substitution. Both maintain the 0.197" (5.00mm) lead spacing and 0.394" Dia (10.00mm) footprint of the URZ1E221MPD. UPJ1E221MPD6 offers 5000 hours lifetime at 105°C with ROHS3 compliance. UPM1E221MPD6 provides the same 5000-hour lifetime with AEC-Q200 automotive qualification and REACH compliance, suitable for applications requiring automotive-grade reliability.

Functional Equivalents (Different Physical Form):

UVZ1E221MPD maintains identical electrical specifications (220 µF, 25 V, ±20%, 1000 Hrs @ 105°C) with 0.138" (4.60mm) lead spacing. This part requires PCB layout modification but is available in higher quantities. UPS1E221MPD provides 2000-hour lifetime with the same lead spacing consideration.

Higher Voltage Alternative:

UVZ1V221MPD is rated at 35 V with 220 µF capacitance and 2000-hour lifetime. This part is suitable for applications where voltage margin is required and maintains the 0.197" (5.00mm) lead spacing for direct mechanical compatibility.

Surface Mount Option:

UWT1E221MNL1GS is an active product offering 220 µF, 25 V in surface mount radial can package. This part is suitable for new designs requiring SMD assembly and provides the longest product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can UPJ1E221MPD6 directly replace URZ1E221MPD on existing PCBs?

A: Yes. UPJ1E221MPD6 maintains identical lead spacing (0.197" / 5.00mm) and footprint diameter (0.394" / 10.00mm), enabling direct PCB substitution without layout modification. Height difference (0.551" vs 0.413") must be verified for clearance in confined spaces.

Q: What is the difference between UPJ1E221MPD and UPJ1E221MPD6?

A: Both are Nichicon UPJ series parts with identical electrical specifications (220 µF, 25 V, ±20%). The primary difference is lifetime rating: UPJ1E221MPD is rated 3000 hours at 105°C, while UPJ1E221MPD6 is rated 5000 hours at 105°C. Lead spacing differs: UPJ1E221MPD uses 0.138" (4.60mm), while UPJ1E221MPD6 uses 0.197" (5.00mm).

Q: Why is UWT1E221MNL1GS listed as Active when others are Obsolete or Not For New Designs?

A: UWT1E221MNL1GS is an active surface mount variant of the 220 µF, 25 V capacitor family. It represents the current production option for new designs requiring SMD assembly. Through-hole variants are generally phased out in favor of surface mount technology.

Q: Can UVZ1V221MPD (35 V) be used in place of URZ1E221MPD (25 V)?

A: Yes, from an electrical standpoint. The 35 V rating provides voltage margin above the 25 V requirement. However, physical dimensions differ: UVZ1V221MPD has 0.492" (12.50mm) height versus URZ1E221MPD's 0.413" (10.50mm). PCB clearance must be verified before substitution.

Q: What does ROHS3 Compliant mean for capacitor selection?

A: ROHS3 Compliant indicates the part meets Restriction of Hazardous Substances Directive 3 requirements, restricting lead, mercury, cadmium, and other hazardous materials. All listed substitute parts carry ROHS3 compliance, ensuring regulatory alignment with current environmental standards.

Q: Are automotive-rated parts (AEC-Q200) required for this application?

A: AEC-Q200 qualification is not required unless the application is automotive. UPM1E221MPD and UPM1E221MPD6 carry AEC-Q200 ratings for automotive applications. General-purpose applications can use non-automotive variants such as UPJ or UPS series.

Q: What is the impact of different lead spacing on PCB compatibility?

A: Lead spacing determines PCB hole pattern compatibility. URZ1E221MPD uses 0.197" (5.00mm) spacing. Substitutes with 0.138" (4.60mm) spacing (UPJ1E221MPD, UPM1E221MPD, UPS1E221MPD, UPW1E221MPD, UVZ1E221MPD) require PCB modification or adapter solutions. Direct mechanical replacement requires matching lead spacing.
