Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Capacitance: 4700 µF (exact match required)
Voltage Rating: 10 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.492" (12.50 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)

Lifetime at 105°C, ripple current ratings, and impedance may vary within acceptable ranges for general-purpose applications. All substitute parts meet or exceed the electrical and mechanical specifications of the original part.

Engineering Selection Recommendations

Direct Substitutes (Identical Electrical and Mechanical Specifications):

UHE1A472MHD is the direct equivalent from Nichicon with identical electrical performance and mechanical dimensions. This part carries ROHS3 compliance, addressing regulatory requirements absent in the obsolete UHE1A472MHT.

Enhanced Performance Alternatives (Active Product Status):

Parts with 10000-hour lifetime ratings (UHW1A472MHD, 10ZLH4700MEFC12.5X30, 10ZLJ4700M12.5X30, EEU-FR1A472L, EKZN100ELL472MK30S) provide extended operational life and improved ripple current handling. These components are suitable for applications requiring higher reliability margins. Height variations range from 1.240" to 1.319", accommodating most PCB layouts with standard through-hole spacing.

Compact Form Factor Option:

EEU-FS1A472 offers the smallest height at 1.063" (27.00 mm) while maintaining 10000-hour lifetime and ROHS3 compliance. This part is appropriate for space-constrained designs.

Equivalent Lifetime Match:

EKY-100ELL472MK35S matches the original 8000-hour lifetime specification with active product status and ROHS3 compliance. Height is 1.437" (36.50 mm), slightly taller than the original.

All substitute parts maintain identical capacitance, voltage rating, tolerance, polarization, lead spacing, case diameter, and mounting type. All active-status alternatives carry ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height?

A: Yes. All substitute parts maintain the 0.197" (5.00 mm) lead spacing and 0.492" (12.50 mm) case diameter. Height variations (ranging from 1.063" to 1.457") do not affect electrical compatibility. Verify PCB clearance for your specific application layout.

Q: What is the difference between 8000-hour and 10000-hour lifetime ratings?

A: Lifetime rating indicates operational duration at maximum rated temperature (105°C). Both ratings are valid for general-purpose applications. The 10000-hour rating provides extended service life for designs requiring higher reliability margins.

Q: Are all substitute parts RoHS compliant?

A: All active-status substitute parts listed carry ROHS3 compliance. The original UHE1A472MHT is RoHS non-compliant. UHE1A472MHD and UHW1A472MHD are ROHS3 compliant alternatives from the same manufacturer.

Q: Does impedance variation affect circuit performance?

A: Impedance values range from 12 to 20 mOhms across substitute parts. For general-purpose applications, these variations are within acceptable tolerance. Applications with strict impedance requirements should specify the preferred range during component selection.

Q: Which substitute offers the best ripple current performance?

A: UHW1A472MHD and EKZN100ELL472MK30S deliver the highest ripple current ratings at 100 kHz (3.795 A and 3.66 A respectively), compared to the original 2.88 A. These parts are suitable for applications with elevated ripple current demands.

Q: Can I mix different substitute parts in the same design?

A: Yes. All substitute parts meet identical electrical specifications for capacitance, voltage, tolerance, and operating temperature. Physical height differences require verification against PCB layout constraints.
