Substitute Part Grouping Explanation

Substitution for the UPB1E102MHD1TO is based on strict electrical and mechanical compatibility. The following parameters must match or exceed the original specification:

Capacitance: 1000 µF (exact match required)
Voltage Rating: 25 V (minimum requirement)
Tolerance: ±20% (acceptable range)
Lead Spacing: 0.197" (5.00 mm) (mechanical fit requirement)
Package Type: Radial, Can (form factor requirement)
Mounting Type: Through Hole (PCB compatibility)
Lifetime @ Temperature: 7000 Hrs @ 105°C (minimum performance requirement)

The substitute parts ELXZ250ETD102MK20S and ELXZ250ETE102MK20S, both manufactured by Chemi-Con, meet all mandatory electrical and mechanical parameters. Both parts are active products with enhanced ripple current ratings and extended operating temperature range (-55°C ~ 105°C), providing superior performance margins compared to the obsolete original.

Engineering Selection Recommendations

Both Chemi-Con substitute parts are suitable direct replacements for the obsolete UPB1E102MHD1TO. Selection between ELXZ250ETD102MK20S and ELXZ250ETE102MK20S depends on packaging requirements and supply chain considerations.

ELXZ250ETD102MK20S and ELXZ250ETE102MK20S are active products with ROHS3 compliance and AEC-Q200 automotive-grade ratings, providing enhanced reliability margins. Both parts maintain identical electrical specifications and mechanical form factors, ensuring PCB-level compatibility without design modification. The extended operating temperature range (-55°C ~ 105°C) and higher ripple current ratings provide performance headroom beyond the original specification.

Frequently Asked Questions (FAQ)

Q: Can ELXZ250ETD102MK20S or ELXZ250ETE102MK20S be used as direct replacements for UPB1E102MHD1TO?

A: Yes. Both substitute parts match the mandatory electrical parameters (1000 µF, 25 V, ±20% tolerance) and mechanical specifications (lead spacing, package type, mounting configuration). No PCB redesign is required.

Q: What is the difference between ELXZ250ETD102MK20S and ELXZ250ETE102MK20S?

A: Both parts are electrically and mechanically identical. The difference lies in packaging format: ELXZ250ETD102MK20S and ELXZ250ETE102MK20S are supplied in Tape & Box (TB) configuration. Selection depends on assembly process requirements and inventory management.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both Chemi-Con parts carry AEC-Q200 automotive-grade certification, making them suitable for automotive and industrial applications requiring enhanced reliability standards.

Q: What are the advantages of the substitute parts over the original?

A: The substitute parts offer extended operating temperature range (-55°C vs. -40°C minimum), higher ripple current capacity (996 mA @ 120 Hz and 1.66 A @ 100 kHz vs. 500 mA and 575 mA), lower impedance (38 mOhms), and active product status with ongoing manufacturer support and ROHS3 compliance.

Q: Is PCB layout modification necessary when switching to substitute parts?

A: No. Identical lead spacing (0.197" / 5.00 mm), can diameter (0.492" / 12.50 mm), and seated height (0.846" / 21.50 mm) ensure direct mechanical compatibility without PCB rework.
