Substitute Part Grouping Explanation

Substitution eligibility for the MALREKA05JS247P00K is determined by strict adherence to the following parameters:

Capacitance: 47 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: 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 (Seated Max): 1.319" (34.60 mm) or 1.299" (33.00 mm) acceptable (within PCB layout tolerance)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Differences in ESR, ripple current ratings, and lifetime specifications reflect manufacturer design variations and do not affect form-fit-function compatibility.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and REACH unaffected status, making them suitable for new designs and production environments. The MALREKA05JS247P00K is obsolete; therefore, selection of an active substitute is required for ongoing availability.

Direct substitutes (B43851F5476M000, ESMQ451ELL470MLN3S, 450PK47MEFC16X31.5) maintain identical electrical and mechanical specifications to the original part and require no design modification.

Enhanced substitutes (EEU-EE2W470, EKMQ451ELL470MLN3S, 450PX47MEFC16X31.5) offer extended operating temperature ranges (-25°C to 105°C) and improved lifetime ratings, providing design margin for applications requiring higher thermal performance. These parts are pin-compatible and mechanically interchangeable with the original part.

All substitute parts are through-hole mounted radial aluminum electrolytic capacitors with identical lead spacing and case dimensions, ensuring PCB compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for MALREKA05JS247P00K?

A: Yes. All listed parts meet the core electrical and mechanical parameters: 47 µF capacitance, 450 V voltage rating, ±20% tolerance, radial can package, 0.295" lead spacing, 0.630" case diameter, and through-hole mounting. Physical height varies between 1.299" and 1.319", which is within standard PCB layout tolerance for through-hole components.

Q: What is the difference between direct and enhanced substitutes?

A: Direct substitutes maintain the original operating temperature range of -25°C to 85°C. Enhanced substitutes extend the upper operating temperature to 105°C and provide longer lifetime ratings at elevated temperatures. Enhanced substitutes are mechanically and electrically interchangeable but offer improved thermal performance for demanding applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

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

A: No. The 0.020" (0.50 mm) height difference is within standard PCB design tolerance for through-hole radial capacitors and does not affect mechanical fit or electrical performance.

Q: Which substitute offers the best long-term reliability?

A: EEU-EE2W470 (Panasonic) provides the highest rated lifetime of 10,000 hours at 105°C, compared to 2000-3000 hours at 85-105°C for other substitutes. This part is suitable for applications requiring extended service life and thermal stability.
