Substitute Part Grouping Explanation

Substitution for the MALREKB00JS447E00K is determined by strict adherence to the following parameters:

Critical Parameters (Must Match):

Capacitance: 4700 µF
Tolerance: ±20%
Package Type: Radial, Can
Lead Spacing: 0.295" (7.50 mm)
Diameter: 0.630" (16.00 mm)
Height: 1.319" (34.60 mm)
Mounting Type: Through Hole
Operating Temperature Range: -55°C to 105°C
Lifetime: 2000 Hrs @ 105°C

Voltage Rating Consideration: Substitute parts are grouped into two categories based on voltage rating. Parts rated at 25 V provide direct equivalence. Parts rated at 35 V are classified as upgrades, offering higher voltage margin while maintaining all other mechanical and electrical specifications.

Engineering Selection Recommendations

For Direct Replacement (Same Voltage Rating): UKA1E472MHD, ECA-1EHG472, and ECA-1EHG472U are parametric equivalents to MALREKB00JS447E00K, matching the 25 V voltage rating and all mechanical dimensions. ECA-1EHG472 and ECA-1EHG472U carry Active product status, making them suitable for new designs and long-term availability. UKA1E472MHD is classified as Not For New Designs but remains available for legacy system maintenance.

For Upgraded Performance (Higher Voltage Margin): EEU-HD1V472 is rated at 35 V while maintaining identical mechanical form factor and all other electrical specifications. This part carries Active product status and provides enhanced voltage margin for applications where circuit conditions may exceed nominal 25 V operation. The upgrade is electrically and mechanically compatible with the original specification.

Compliance and Availability: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. ECA-1EHG472, ECA-1EHG472U, and EEU-HD1V472 are classified as Active products with substantial inventory availability, ensuring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can UKA1E472MHD be used as a direct replacement for MALREKB00JS447E00K? A: Yes. UKA1E472MHD matches all critical parameters including capacitance, voltage rating, tolerance, package dimensions, and lead spacing. The height difference of 0.020" (0.50 mm) is within acceptable mechanical tolerance for through-hole mounting. However, UKA1E472MHD is classified as Not For New Designs; for new applications, ECA-1EHG472 or EEU-HD1V472 are preferred.

Q: What is the difference between ECA-1EHG472 and ECA-1EHG472U? A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is packaging designation. Both are Active products suitable for new designs and carry equivalent performance characteristics.

Q: Why is EEU-HD1V472 listed as an upgrade rather than a direct substitute? A: EEU-HD1V472 is rated at 35 V compared to the 25 V rating of MALREKB00JS447E00K. While all other parameters match exactly, the higher voltage rating represents an enhancement. This part is electrically and mechanically compatible and provides additional voltage margin for circuit protection.

Q: Are all substitute parts through-hole mounted? A: Yes. All substitute parts listed maintain through-hole mounting type with identical lead spacing of 0.295" (7.50 mm), ensuring direct PCB compatibility without layout modifications.

Q: Do all substitute parts meet current regulatory compliance? A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the significance of product status classification? A: Product status indicates lifecycle stage. Active products are in current production with guaranteed long-term availability. Not For New Designs indicates the part remains available but is not recommended for new circuit designs. Obsolete indicates the part is no longer manufactured.
