KY25VB47RM5X11LL Equivalent & Substitute Parts

Part Overview

The KY25VB47RM5X11LL is a 47 µF, 25 V aluminum electrolytic capacitor in radial, can package manufactured by Chemi-Con. This component is classified as obsolete, indicating discontinued production and limited availability in the market. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 5000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance performance in through-hole mounting configurations.

Due to its obsolete status, identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitution of the KY25VB47RM5X11LL is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 47 µF (exact match)
• Voltage rating: 25 V (exact match)
• Tolerance: ±20% (exact match)
• Polarization: Polar (exact match)
• Operating temperature range: -40°C ~ 105°C (exact match)
• Lifetime specification: 5000 Hrs @ 105°C (exact match)

Mechanical Equivalence Requirements:

• Package type: Radial, Can (exact match)
• Mounting type: Through Hole (exact match)
• Lead spacing: 0.079" (2.00mm) (exact match)
• Diameter: 0.197" (5.00mm) (exact match)

The substitute part EEU-EB1E470S meets all electrical and mechanical equivalence criteria. Physical height variation (0.433" vs 0.472") does not preclude substitution in through-hole applications where vertical clearance permits the additional 0.039" (1.00mm) dimension.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: EEU-EB1E470S

The EEU-EB1E470S is the direct electrical and mechanical equivalent for the obsolete KY25VB47RM5X11LL. Selection of this substitute is based on the following factors:

1. Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

2. Regulatory Compliance: The EEU-EB1E470S is ROHS3 compliant, whereas the KY25VB47RM5X11LL is RoHS non-compliant. This compliance status is relevant for applications subject to RoHS regulations.

3. Electrical Equivalence: All critical electrical parameters match exactly: 47 µF capacitance, 25 V voltage rating, ±20% tolerance, -40°C to 105°C operating range, and 5000-hour lifetime at 105°C.

4. Mechanical Compatibility: Lead spacing (2.00mm), diameter (5.00mm), and package type (radial, can through-hole) are identical. The height difference of 1.00mm (0.472" vs 0.433") must be verified against available vertical clearance in the target application.

5. Trade-off Consideration: The substitute exhibits lower ripple current ratings (55 mA @ 120 Hz and 71.5 mA @ 100 kHz versus 84 mA and 210 mA respectively). This difference is acceptable for general-purpose applications where the main part's ripple current specifications were not critical design constraints.

Frequently Asked Questions (FAQ)

Q: Can EEU-EB1E470S be used as a direct replacement for KY25VB47RM5X11LL?

A: Yes. The EEU-EB1E470S meets all electrical and mechanical equivalence criteria: identical capacitance (47 µF), voltage rating (25 V), tolerance (±20%), operating temperature range (-40°C to 105°C), lifetime (5000 Hrs @ 105°C), lead spacing (2.00mm), diameter (5.00mm), and package type (radial, can through-hole). Physical height differs by 1.00mm; verify available vertical clearance in your PCB layout.

Q: What is the significance of the height difference between these parts?

A: The KY25VB47RM5X11LL has a maximum seated height of 0.433" (11.00mm), while the EEU-EB1E470S measures 0.472" (12.00mm). This 1.00mm difference must be evaluated against your circuit board design. If vertical clearance is constrained, this dimension becomes a limiting factor. If clearance is adequate, the height difference does not affect electrical performance or functionality.

Q: Why do the ripple current ratings differ between these parts?

A: Ripple current specifications reflect the internal construction and thermal characteristics of each capacitor design. The KY25VB47RM5X11LL specifies 84 mA @ 120 Hz and 210 mA @ 100 kHz, while the EEU-EB1E470S specifies 55 mA @ 120 Hz and 71.5 mA @ 100 kHz. For general-purpose applications, the substitute's ripple current ratings are sufficient. If your application requires the higher ripple current handling of the original part, this specification must be re-evaluated against actual circuit demands.

Q: Is the RoHS compliance difference important?

A: The EEU-EB1E470S is ROHS3 compliant, whereas the KY25VB47RM5X11LL is RoHS non-compliant. If your application or market region requires RoHS compliance, the substitute part satisfies this requirement. If RoHS compliance is not a requirement, this difference is not relevant to component selection.

Q: Are there any other substitute options available?

A: Based on the provided data, EEU-EB1E470S is the identified equivalent substitute. No additional alternatives are specified in the reference materials.

Q: What should I verify before implementing this substitution?

A: Verify the following: (1) Vertical clearance on the PCB accommodates the 0.472" (12.00mm) maximum height; (2) Ripple current requirements do not exceed the substitute's ratings of 55 mA @ 120 Hz or 71.5 mA @ 100 kHz; (3) RoHS compliance requirements align with the substitute's ROHS3 status; (4) Lead spacing and diameter compatibility with existing PCB footprints.
