Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LKS1V472MESZ is determined by strict equivalence across the following critical parameters:

• Capacitance: 4700 µF (exact match required)
• Voltage Rating: 35 V (minimum; higher ratings acceptable)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Lifetime @ Temperature: 1000 Hrs @ 85°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Physical dimensions (diameter and height) may vary within the snap-in package envelope provided all other electrical and mechanical parameters remain equivalent. Ripple current capacity may differ between substitutes while maintaining functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical equivalence to the LKS1V472MESZ within the constraints of the snap-in package form factor. Selection among substitutes should be based on:

Physical fit within the PCB layout. The LKS1V472MESZ has a 22.00 mm diameter and 30.00 mm height. Substitutes with larger diameters (LKG1V472MESBBK at 30.00 mm diameter) or greater heights (LKG1V472MESZBK at 45.00 mm, LKS1H472MESZ at 40.00 mm, LKS1V472MESY at 35.00 mm) require verification of available board space.

Voltage rating consideration. The LKS1H472MESZ provides a 50 V rating versus the 35 V rating of the original part. This higher voltage rating is electrically compatible and may be selected for applications requiring additional voltage margin.

Ripple current capacity. Substitutes LKG1V472MESBBK, LKG1V472MESZBK, and LKS1H472MESZ offer increased ripple current handling (2.55 A to 2.7 A @ 120 Hz) compared to the original 2.1 A specification. This provides enhanced thermal performance in high-ripple applications.

All substitute parts carry ROHS3 compliance and obsolete product status consistent with the original part, ensuring regulatory alignment and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can LKS1V472MESY be used as a direct replacement for LKS1V472MESZ?

A: LKS1V472MESY is electrically equivalent with identical capacitance, voltage, tolerance, and temperature specifications. The primary difference is physical diameter (20.00 mm versus 22.00 mm). Substitution is valid provided the smaller diameter accommodates the PCB layout.

Q: Is LKS1H472MESZ compatible with a 35 V circuit design?

A: Yes. LKS1H472MESZ carries a 50 V rating, which exceeds the 35 V requirement of the original circuit. Higher voltage-rated capacitors are electrically compatible in lower-voltage applications and provide additional safety margin.

Q: What is the significance of the diameter and height variations among substitutes?

A: Snap-in aluminum electrolytic capacitors maintain consistent lead spacing (10.00 mm) and mounting interface across the product family. Diameter and height variations reflect different internal construction and ripple current ratings. Physical fit must be verified against PCB layout constraints before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes carry ROHS3 compliance status, matching the regulatory requirement of the original LKS1V472MESZ.

Q: Can substitutes with higher ripple current ratings be used interchangeably?

A: Yes. Increased ripple current capacity is a performance enhancement that does not compromise compatibility. Substitutes with higher ripple current ratings (LKG1V472MESBBK, LKG1V472MESZBK, LKS1H472MESZ) provide improved thermal performance in applications with elevated AC ripple content.
