Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KY50VB2R2M5X11LL is determined by strict alignment of the following electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Capacitance: 2.2 µF
• Voltage Rating: 50 V
• Tolerance: ±20%
• Polarization: Polar

Mechanical Parameters (Must Match):

• Lead Spacing: 0.079" (2.00mm)
• Size / Dimension: 0.197" Dia (5.00mm)
• Mounting Type: Through Hole
• Package / Case: Radial, Can

Acceptable Variations:

• Lifetime @ Temperature: Equal to or greater than 5000 Hrs @ 105°C
• Operating Temperature Range: Equal to or wider than -40°C ~ 105°C
• Height - Seated (Max): Physical height may vary within PCB layout constraints
• Ripple Current ratings: May vary based on impedance characteristics
• Product Status: Active status preferred for long-term availability

The following parts meet these substitution criteria:

1. 860160672003 (Würth Elektronik WCAP-ATLL Series) – Active status, meets all electrical and mechanical parameters; lifetime rated at 4000 Hrs @ 105°C
2. EEU-EB1H2R2S (Panasonic Electronic Components EB-A Series) – Active status, meets all electrical and mechanical parameters; lifetime rated at 5000 Hrs @ 105°C

Parameter Comparison

Engineering Selection Recommendations

EEU-EB1H2R2S (Panasonic Electronic Components) is the primary substitute for the KY50VB2R2M5X11LL. This part maintains identical electrical specifications (2.2 µF, 50 V, ±20% tolerance) and mechanical compatibility (lead spacing, diameter, through-hole mounting). The EEU-EB1H2R2S carries Active product status, ensuring long-term availability and supply chain stability. It meets ROHS3 compliance requirements and provides equivalent 5000-hour lifetime rating at 105°C. Current inventory of 28,670 units supports production requirements.

860160672003 (Würth Elektronik WCAP-ATLL Series) serves as a secondary substitute. This part meets all electrical and mechanical substitution criteria with identical capacitance, voltage rating, tolerance, and lead spacing. The 860160672003 carries Active product status and ROHS3 compliance. The primary consideration is the reduced lifetime rating of 4000 hours at 105°C compared to the original 5000-hour specification. The extended operating temperature range (-55°C ~ 105°C) provides additional thermal margin. Inventory availability of 2,680 units supports component procurement.

Both substitute parts are suitable for direct PCB replacement. Height variations (11.00mm original vs. 12.50mm and 12.00mm for substitutes) require verification within specific PCB layout constraints. Active product status and regulatory compliance of both substitutes support long-term design continuity.

Frequently Asked Questions (FAQ)

Q: Can the 860160672003 be used as a direct replacement for the KY50VB2R2M5X11LL?

A: The 860160672003 meets all electrical and mechanical substitution criteria: 2.2 µF capacitance, 50 V voltage rating, ±20% tolerance, 0.079" lead spacing, 0.197" diameter, and through-hole radial can package. The primary difference is the reduced lifetime rating of 4000 hours at 105°C versus the original 5000 hours. Physical height is 12.50mm compared to the original 11.00mm; verify PCB layout clearance before implementation.

Q: What is the key difference between the EEU-EB1H2R2S and 860160672003 substitutes?

A: Both parts match the electrical specifications of the KY50VB2R2M5X11LL. The EEU-EB1H2R2S maintains the original 5000-hour lifetime rating at 105°C, while the 860160672003 is rated for 4000 hours. The 860160672003 provides an extended operating temperature range of -55°C to 105°C compared to -40°C to 105°C for both the original and EEU-EB1H2R2S. Physical heights differ: EEU-EB1H2R2S is 12.00mm, 860160672003 is 12.50mm, and the original is 11.00mm.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both the EEU-EB1H2R2S and 860160672003 carry ROHS3 compliance certification. The original KY50VB2R2M5X11LL is RoHS non-compliant. If RoHS compliance is a design requirement, either substitute part satisfies regulatory requirements.

Q: Will the increased height of substitute parts affect PCB assembly?

A: The substitute parts have greater seated heights than the original: EEU-EB1H2R2S at 12.00mm and 860160672003 at 12.50mm compared to the original 11.00mm. Verify clearance within your specific PCB layout, including proximity to adjacent components, enclosure constraints, and any mechanical fixtures. Lead spacing and diameter remain identical, ensuring footprint compatibility.

Q: What is the impact of impedance differences between the parts?

A: The original KY50VB2R2M5X11LL has an impedance of 2.5 Ohms, while the 860160672003 is rated at 3.6 Ohms. The EEU-EB1H2R2S impedance is not specified in available data. Impedance affects ripple current handling and high-frequency performance. For general-purpose applications, the impedance variation is within acceptable tolerances. For noise-sensitive or high-ripple-current applications, conduct circuit analysis to confirm performance margins.

Q: Can I use the 860160672003 in applications requiring the full 5000-hour lifetime specification?

A: The 860160672003 is rated for 4000 hours at 105°C, which is 1000 hours less than the original 5000-hour specification. If your application requires the full 5000-hour lifetime guarantee, use the EEU-EB1H2R2S, which maintains this rating. For applications with lower lifetime requirements or shorter operational duty cycles, the 860160672003 is acceptable.

Q: Are all three parts suitable for the same general-purpose applications?

A: Yes. All three parts are rated for general-purpose applications with identical capacitance (2.2 µF), voltage (50 V), and tolerance (±20%) specifications. Electrical functionality is equivalent across all three components. Selection should be based on product availability, compliance requirements, lifetime specifications, and physical height constraints within your specific design.
