Substitute Part Grouping Explanation

Substitution eligibility for the LKS1J472MESA is determined by the following critical parameters:

Capacitance: Must be 4700 µF (±20% tolerance acceptable)
Voltage Rating: Minimum 63 V (higher ratings are acceptable as they provide backward compatibility)
Package Type: Radial, Can - Snap-In with through-hole mounting
Lead Spacing: 0.394" (10.00 mm) for PCB compatibility
Polarization: Polar configuration required
Operating Temperature Range: Must support -40°C ~ 85°C minimum
RoHS Compliance: ROHS3 Compliant status required

Three substitute parts meet these criteria and are grouped as follows:

Direct Equivalent (Same Voltage Rating): LKS1J472MESB and SLPX472M063C7P3 maintain the 63 V rating with identical capacitance and package specifications.

Voltage Upgrade (Higher Rating): LKS1K472MESA provides 80 V rating with the same 4700 µF capacitance, suitable for applications requiring enhanced voltage margin.

Engineering Selection Recommendations

LKS1J472MESB: Direct equivalent with identical electrical specifications. Differs only in physical dimensions (larger diameter and shorter height). Suitable for direct replacement where PCB layout accommodates the 1.181" diameter can. Product status is obsolete.

LKS1K472MESA: Provides voltage upgrade to 80 V while maintaining 4700 µF capacitance and 10.00 mm lead spacing. Increased ripple current rating (3.6 A @ 120 Hz) offers enhanced performance margin. Physical dimensions differ (0.984" diameter, 1.969" height). Product status is obsolete.

SLPX472M063C7P3: Active product from Cornell Dubilier Electronics with identical voltage and capacitance ratings. Offers extended lifetime of 3000 hours at 85°C compared to 1000 hours for Nichicon LKS series. Physical dimensions match the original LKS1J472MESA (0.984" diameter, 1.575" height). ESR specification provided at 85 mOhm @ 120 Hz. ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can LKS1J472MESB be used as a direct replacement for LKS1J472MESA?

A: Yes, LKS1J472MESB is electrically equivalent with identical capacitance (4700 µF), voltage rating (63 V), tolerance (±20%), and operating temperature range (-40°C ~ 85°C). The primary difference is physical dimensions: the can diameter increases from 0.984" to 1.181" and height decreases from 1.575" to 1.181". PCB layout must accommodate these dimensional changes.

Q: What is the advantage of using LKS1K472MESA over LKS1J472MESA?

A: LKS1K472MESA provides a higher voltage rating of 80 V versus 63 V, offering increased voltage margin for the same 4700 µF capacitance. Ripple current capability increases to 3.6 A @ 120 Hz. Physical dimensions differ: diameter remains 0.984" but height increases to 1.969". This part is suitable for applications requiring enhanced voltage headroom.

Q: Why is SLPX472M063C7P3 recommended as an upgrade?

A: SLPX472M063C7P3 maintains the same electrical specifications as LKS1J472MESA (4700 µF, 63 V, ±20% tolerance) with identical physical dimensions (0.984" diameter, 1.575" height). The key advantage is active product status and extended lifetime of 3000 hours at 85°C compared to 1000 hours for the obsolete Nichicon LKS series. ESR is specified at 85 mOhm @ 120 Hz.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all substitute parts listed (LKS1J472MESB, LKS1K472MESA, and SLPX472M063C7P3) are ROHS3 compliant and REACH unaffected, matching the compliance status of the original LKS1J472MESA.

Q: What is the lead spacing requirement for PCB compatibility?

A: All listed parts maintain 0.394" (10.00 mm) lead spacing, ensuring PCB footprint compatibility. Physical can diameter and height may vary, requiring verification of available board space.

Q: Can a higher voltage-rated part substitute for a lower voltage requirement?

A: Yes, LKS1K472MESA (80 V rating) is electrically compatible with applications designed for 63 V operation. Higher voltage ratings provide backward compatibility and increased safety margin. Physical dimensions must still be verified for PCB fit.
