Vishay Sprague 511D475M100AA4D Equivalent & Substitute Parts

Part Overview

The Vishay Sprague 511D475M100AA4D is a 4.7 µF, 100 V aluminum electrolytic capacitor in radial, can package configuration. This component is classified as Active status and serves general-purpose applications requiring polarized capacitive energy storage. Substitute parts become necessary when addressing inventory constraints, extended lead times, or when design requirements permit operation at alternative voltage ratings or with improved reliability specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 511D475M100AA4D is determined by the following mandatory parameters:

• Capacitance: Must be 4.7 µF (exact match required)
• Tolerance: Must be ±20% (exact match required)
• Polarization: Must be Polar (exact match required)
• Lead Spacing: Must be 0.098" (2.50mm) (exact match required)
• Package / Case: Must be Radial, Can (exact match required)
• Mounting Type: Must be Through Hole (exact match required)

Voltage Rating Flexibility: Rated voltage may be equal to or greater than 100 V. Higher voltage ratings provide backward compatibility in circuits designed for 100 V operation.

Lifetime and ESR: These parameters may vary among substitutes without affecting functional compatibility, provided the application does not impose specific reliability or frequency-response constraints.

The following parts meet all substitution criteria:

• 200LLE4R7MEFC6.3X11 (Rubycon) – 200 V rated, extended lifetime
• UPJ2A4R7MED (Nichicon) – 100 V rated, equivalent voltage class
• UVY2D4R7MED (Nichicon) – 200 V rated, higher voltage margin
• UVY2E4R7MED (Nichicon) – 250 V rated, maximum voltage margin
• UVZ2C4R7MED (Nichicon) – 160 V rated, intermediate voltage option

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 200LLE4R7MEFC6.3X11 (Rubycon)

This substitute offers Active product status with RoHS3 compliance and REACH Unaffected certification. The 200 V rating provides voltage margin above the original 100 V specification. Extended lifetime of 12000 Hrs @ 105°C exceeds the original 1000 Hrs specification. Physical dimensions accommodate standard through-hole PCB layouts with 2.50mm lead spacing.

Secondary Recommendation: UPJ2A4R7MED (Nichicon)

This substitute maintains the original 100 V voltage rating with equivalent electrical performance. Extended operating temperature range (-55°C ~ 105°C) provides additional thermal margin. RoHS3 compliance and REACH Unaffected certification are provided. Note: Product status is Obsolete; inventory availability should be confirmed before design commitment.

Alternative Options: UVY2D4R7MED, UVY2E4R7MED, UVZ2C4R7MED (Nichicon)

These substitutes provide voltage ratings of 200 V, 250 V, and 160 V respectively, offering design flexibility for circuits requiring higher voltage margins. All three maintain RoHS3 compliance and REACH Unaffected certification. All three are classified as Obsolete; long-term availability is not assured.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute with a higher voltage rating than the original 100 V specification?

A: Yes. A capacitor rated for higher voltage (200 V, 250 V, or 160 V) operates safely in a 100 V circuit. The higher voltage rating does not affect circuit function and provides additional safety margin. Physical dimensions must remain compatible with PCB layout constraints.

Q: What is the significance of "Obsolete" product status?

A: Obsolete status indicates the manufacturer has discontinued active production. Existing inventory may be available through authorized distributors, but long-term supply cannot be assured. For new designs, Active-status parts such as 200LLE4R7MEFC6.3X11 are preferred.

Q: Are all substitute parts RoHS compliant?

A: The original 511D475M100AA4D is RoHS non-compliant. All listed substitutes are RoHS3 compliant, meeting current environmental regulations for new equipment manufacturing.

Q: Do dimensional differences affect PCB compatibility?

A: Lead spacing remains constant at 0.098" (2.50mm) across all substitutes, ensuring PCB footprint compatibility. Minor variations in can diameter (6.00mm to 6.30mm) and height (12.00mm to 13.00mm) are within standard through-hole component tolerances and do not affect mounting.

Q: What is the difference between ESR and impedance specifications?

A: ESR (Equivalent Series Resistance) is measured at a specific frequency (120 Hz for the original part). Impedance is the total opposition to AC current flow at a given frequency. Both parameters affect high-frequency performance. The original part specifies ESR; substitute parts may not provide this value, indicating design flexibility in frequency-response requirements.

Q: Can I substitute based on capacitance and voltage alone?

A: No. Substitution requires matching capacitance (4.7 µF), tolerance (±20%), polarization (Polar), lead spacing (2.50mm), package type (Radial, Can), and mounting method (Through Hole). All these parameters must align for functional compatibility.
