Substitute Part Grouping Explanation

Substitution of the MALREKA00JS247PG0K is determined by strict equivalence across the following electrical and mechanical parameters:

Capacitance Value: 47 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package Configuration: Radial, Can with identical lead spacing (0.295" / 7.50 mm)
Physical Dimensions: Case diameter 0.630" (16.00 mm) and compatible height specifications
Mounting Interface: Through-hole PCB mounting
Polarization: Polar configuration

All substitute parts listed maintain these core parameters. Variations in lifetime ratings, operating temperature ranges, ESR values, and ripple current specifications represent performance enhancements or different thermal characteristics but do not affect basic functional compatibility in applications designed for the original part.

Engineering Selection Recommendations

All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. The original MALREKA00JS247PG0K is obsolete; therefore, selection of an active substitute is necessary for new production and ongoing support.

For applications operating within the original thermal envelope (-25°C to 85°C), direct parametric equivalents include ESMQ451ELL470MLN3S and 450PK47MEFC16X31.5, both maintaining identical lifetime specifications of 2000 hours at 85°C.

For applications requiring extended operational life or higher temperature tolerance, active substitutes with enhanced thermal performance include B43851F5476M000 (3000 hours at 105°C), 450PX47MEFC16X31.5 (2000 hours at 105°C), EKMQ451ELL470MLN3S (2000 hours at 105°C), and EEU-EE2W470 (10000 hours at 105°C). These parts maintain full electrical and mechanical compatibility while offering superior reliability margins.

All substitute parts are currently in active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for MALREKA00JS247PG0K?

A: Yes. All listed parts maintain identical capacitance (47 µF), voltage rating (450 V), tolerance (±20%), lead spacing (0.295" / 7.50 mm), case diameter (0.630" / 16.00 mm), and through-hole mounting configuration. Physical height varies minimally (1.299" to 1.319"), remaining within standard PCB layout tolerances.

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents maintain the original lifetime specification of 2000 hours at 85°C (ESMQ451ELL470MLN3S, 450PK47MEFC16X31.5). Upgrade substitutes offer extended lifetime ratings or higher operating temperature ranges while maintaining all core electrical and mechanical parameters. Selection depends on application thermal requirements and desired reliability margin.

Q: Are there any compatibility concerns with PCB layout or footprint?

A: No. All substitute parts use identical lead spacing (0.295" / 7.50 mm) and case diameter (0.630" / 16.00 mm). Maximum height specifications range from 1.299" to 1.319", which is negligible for standard through-hole PCB designs. Existing footprints and layouts require no modification.

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

A: EEU-EE2W470 provides the highest lifetime rating at 10000 hours at 105°C, offering maximum reliability margin for critical applications. This part maintains all electrical and mechanical compatibility with the original specification.

Q: Do all substitutes meet current regulatory compliance?

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