Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPB2E470MHD1TO is determined by strict electrical and mechanical compatibility criteria:

Electrical Parameters (Must Match):

• Capacitance: 47 µF
• Voltage Rating: 250 V
• Tolerance: ±20%

Mechanical Parameters (Must Match):

• Package Type: Radial, Can
• Mounting Type: Through Hole
• Lead Spacing: 0.197" (5.00 mm)
• Case Diameter: 0.492" (12.50 mm)

The EKXG251ELL470MK20S from Chemi-Con meets all mandatory electrical and mechanical parameters. Additional performance improvements in this substitute include extended lifetime rating and enhanced ripple current handling, which provide superior reliability without compromising form-factor compatibility.

Parameter Comparison

Engineering Selection Recommendations

The EKXG251ELL470MK20S is a direct electrical and mechanical substitute for the UPB2E470MHD1TO. The substitute part maintains identical capacitance, voltage rating, tolerance, lead spacing, and case diameter specifications, ensuring PCB-level compatibility without layout modifications.

The substitute component offers extended product lifecycle support through active manufacturing status, compared to the obsolete status of the original part. The EKXG251ELL470MK20S is ROHS3 compliant, providing alignment with current environmental and regulatory standards. Both parts share identical REACH and ECCN classifications, confirming regulatory equivalence.

The substitute exhibits improved thermal performance characteristics, including extended lifetime rating (10000 hours versus 5000 hours at 105°C) and enhanced ripple current capacity at both low and high frequencies. The reduced seated height (0.787" versus 1.043") provides additional design flexibility for space-constrained applications while maintaining full electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the EKXG251ELL470MK20S be used as a direct replacement for the UPB2E470MHD1TO?

A: Yes. Both components share identical capacitance (47 µF), voltage rating (250 V), tolerance (±20%), lead spacing (0.197"), and case diameter (0.492"). Through-hole mounting compatibility is confirmed. No PCB modifications are required.

Q: What are the key differences between these parts?

A: The substitute part offers extended lifetime rating (10000 hours at 105°C versus 5000 hours), higher ripple current capacity, wider operating temperature range (-40°C to 105°C versus -25°C to 105°C), and reduced seated height (0.787" versus 1.043"). The substitute maintains active product status with ROHS3 compliance.

Q: Does the reduced height of the substitute part affect compatibility?

A: No. The reduced seated height (0.787" versus 1.043") is a dimensional improvement that provides additional clearance in the assembly. This does not compromise electrical performance or mechanical fit, as lead spacing and case diameter remain identical.

Q: Are there any compliance or regulatory differences?

A: Both parts share identical REACH and ECCN classifications. The substitute part is ROHS3 compliant, providing enhanced regulatory alignment with current environmental standards.

Q: What is the inventory status of these parts?

A: The original UPB2E470MHD1TO is obsolete with limited stock availability (766 pcs). The substitute EKXG251ELL470MK20S is in active production with substantial inventory (68374 pcs), ensuring long-term supply chain reliability.
