Substitution of the 476HSM050M is determined by strict electrical and mechanical compatibility criteria. All substitute parts must satisfy the following requirements:

Mandatory Electrical Parameters:

Capacitance: 47 µF
Tolerance: ±20%
Voltage Rating: 50 V
Polarization: Polar
Operating Temperature: -40°C to 125°C minimum

Mandatory Mechanical Parameters:

Mounting Type: Through Hole
Package Type: Radial, Can
Lead Spacing: 0.138" (3.50mm)
Diameter: 0.315" (8.00mm)

Acceptable Variations:

Height may vary within component footprint constraints
Lifetime at temperature may equal or exceed 2000 Hrs @ 125°C
Operating temperature upper limit may exceed 125°C

Engineering Selection Recommendations

Direct Equivalent Substitutes (Preferred for Pin-Compatible Replacement):

EEU-TA1H470S (Panasonic Electronic Components) and UBT1H470MPD8 (Nichicon) function as direct electrical equivalents to the 476HSM050M. Both parts maintain identical capacitance, voltage rating, tolerance, and operating temperature specifications. EEU-TA1H470S is classified as active product status with ROHS3 compliance and REACH unaffected designation. UBT1H470MPD8 carries active product status with ROHS3 compliance and REACH affected designation, with automotive application rating. Both parts accommodate the standard 0.138" (3.50mm) lead spacing and 0.315" (8.00mm) diameter footprint.

Upgraded Substitutes (Enhanced Performance for Demanding Applications):

50RX3047M8X11.5 and 50RX3047MRK8X11.5 (Rubycon, RX30 series) provide upgraded performance characteristics while maintaining electrical compatibility. Both parts extend the operating temperature range to -40°C to 130°C and offer 2000 hours lifetime at 130°C, exceeding the original specification. Both carry AEC-Q200 automotive qualification and ROHS3 compliance. The primary distinction between these two variants is height: 50RX3047M8X11.5 measures 0.512" (13.00mm), matching the original part height, while 50RX3047MRK8X11.5 measures 0.531" (13.50mm). Lead spacing and diameter remain compatible at 0.138" (3.50mm) and 0.315" (8.00mm) respectively.

Alternative Substitute (Different Footprint):

860130675005 (Würth Elektronik, WCAP-ATET series) maintains electrical equivalence but differs in mechanical footprint. This part features 0.197" (5.00mm) lead spacing and 0.394" (10.00mm) diameter, requiring PCB layout modification. The component is active product status with ROHS3 compliance and REACH unaffected designation. Selection of this part is appropriate only when PCB redesign is feasible.

Selection Criteria:

For direct replacement without PCB modification, select EEU-TA1H470S or UBT1H470MPD8. For applications requiring extended temperature performance or automotive qualification, select 50RX3047M8X11.5 or 50RX3047MRK8X11.5 based on height constraints. All recommended substitutes are active product status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can EEU-TA1H470S directly replace 476HSM050M without PCB modification?

A: Yes. EEU-TA1H470S maintains identical lead spacing (0.138" / 3.50mm), diameter (0.315" / 8.00mm), and electrical specifications. The height difference (0.492" vs. 0.512") does not affect electrical function or standard PCB mounting.

Q: What is the difference between 50RX3047M8X11.5 and 50RX3047MRK8X11.5?

A: Both parts are electrically identical with identical lead spacing and diameter. The primary difference is seated height: 50RX3047M8X11.5 measures 0.512" (13.00mm), while 50RX3047MRK8X11.5 measures 0.531" (13.50mm). Select based on available vertical clearance on the PCB.

Q: Why does 860130675005 have different lead spacing?

A: 860130675005 features 0.197" (5.00mm) lead spacing and 0.394" (10.00mm) diameter, differing from the standard 0.138" (3.50mm) spacing and 0.315" (8.00mm) diameter of the original part. This part requires PCB layout modification and is suitable only when redesign is feasible.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts (EEU-TA1H470S, UBT1H470MPD8, 50RX3047M8X11.5, 50RX3047MRK8X11.5, and 860130675005) carry ROHS3 compliance certification.

Q: Which substitute part is recommended for automotive applications?

A: UBT1H470MPD8 (Nichicon) and both Rubycon RX30 series parts (50RX3047M8X11.5 and 50RX3047MRK8X11.5) carry automotive application ratings. The Rubycon parts additionally carry AEC-Q200 qualification.

Q: What is the impact of different ESR values on circuit performance?

A: ESR differences between substitute parts do not affect basic capacitance function. The original 476HSM050M specifies 3.527 Ohm @ 120Hz. Substitute parts with lower ESR values (such as 280 mOhms in Rubycon parts) provide improved ripple current handling and reduced heat generation, representing performance enhancement rather than degradation.

Q: Can I use 860130675005 if my PCB has limited horizontal space?

A: No. 860130675005 has larger diameter (0.394" / 10.00mm vs. 0.315" / 8.00mm) and wider lead spacing (0.197" / 5.00mm vs. 0.138" / 3.50mm), requiring more PCB space. This part is suitable only when PCB redesign accommodates the larger footprint.

Q: What is the inventory status of substitute parts?

A: EEU-TA1H470S has 5995 units in stock. UBT1H470MPD8 has 1936 units. 50RX3047M8X11.5 has 9512 units. 50RX3047MRK8X11.5 has 1124 units. 860130675005 has 2160 units. All parts are new original stock.
