Substitute Part Grouping Explanation

Substitution for the MALREKB00JS247XG0K is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance: 47 µF (exact match required)
Voltage Rating: 400 V minimum (higher voltage ratings are acceptable)
Tolerance: ±20% (exact match required)
Package: Radial, Can (exact match required)
Lead Spacing: 0.295" (7.50 mm) (exact match required)
Case Diameter: 0.630" (16.00 mm) (exact match required)
Height: 1.319" (34.60 mm) maximum (equal or lower acceptable)
Mounting: Through Hole (exact match required)
Polarization: Polar (exact match required)

Substitute parts are grouped into two categories:

Category 1: Direct 400 V Substitutes — Parts maintaining the original 400 V voltage rating with identical mechanical dimensions and electrical specifications.

Category 2: Upgraded Voltage Substitutes — Parts rated at 450 V or higher, which are electrically compatible in 400 V applications due to voltage derating principles, while maintaining identical mechanical form factors.

All substitute parts listed comply with ROHS3 and maintain the same through-hole radial can package configuration.

Frequently Asked Questions (FAQ)

Q: Can I use a 450 V rated capacitor in place of the 400 V original part?

A: Yes. A 450 V rated capacitor is electrically compatible in a 400 V application. The higher voltage rating provides derating margin and does not affect circuit operation. All mechanical dimensions remain identical.

Q: What is the difference between the 400 V and 450 V substitute options?

A: The primary difference is voltage rating. Both maintain 47 µF capacitance, ±20% tolerance, and identical physical dimensions. The 450 V parts provide additional voltage margin and are suitable for applications requiring enhanced reliability or where voltage transients may occur.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this document are ROHS3 compliant, matching the compliance status of the original MALREKB00JS247XG0K.

Q: Does the height difference between 1.299" and 1.319" affect PCB layout?

A: No. The original part specifies a maximum height of 1.319". Substitute parts with 1.299" height are shorter and will fit within the same PCB footprint without modification.

Q: Which substitute offers the longest operational lifetime?

A: B43890A9476M000 offers 15000 hours at 105°C, the longest lifetime among all 400 V rated options. EEU-EE2W470 offers 10000 hours at 105°C among 450 V rated options.

Q: Can I use EGXE401ELL470MLN3S in standard applications?

A: Yes. EGXE401ELL470MLN3S is a direct 400 V substitute with extended temperature range (-25°C to 125°C) and AEC-Q200 automotive qualification. It is suitable for both standard and automotive applications.

Q: Are the lead spacing and case diameter identical across all substitutes?

A: Yes. All substitute parts maintain 0.295" (7.50 mm) lead spacing and 0.630" (16.00 mm) case diameter, ensuring direct PCB compatibility without layout modification.
