• Tolerance: ±20% (exact match required)
• Lifetime: 7000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)

Critical Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.138" (3.50mm) (exact match required)
• Size / Dimension: 0.315" Dia (8.00mm) (exact match required)
• Height - Seated (Max): 0.453" (11.50mm) (exact match required)

Performance Parameters:

• Impedance: 170 mOhms (exact match required)

Substitute parts must satisfy all critical parameters to ensure direct compatibility in PCB layouts, circuit designs, and thermal management requirements.

Parameter Comparison

Engineering Selection Recommendations

The UHE1H101MPD manufactured by Nichicon is a parametric equivalent to the KY50VB101M8X11LL. Both components share identical electrical and mechanical specifications across all critical parameters: 100 µF capacitance, 50 V voltage rating, ±20% tolerance, 7000-hour lifetime at 105°C, and identical physical dimensions and lead spacing.

Product Status Consideration: The KY50VB101M8X11LL is classified as obsolete. The UHE1H101MPD is classified as "Not For New Designs," indicating limited availability for future production. For new designs requiring long-term component availability, evaluation of alternative suppliers and series with active production status is necessary.

Compliance Consideration: The KY50VB101M8X11LL is RoHS non-compliant. The UHE1H101MPD is ROHS3 compliant, providing regulatory advantage for applications subject to RoHS requirements. The UHE1H101MPD is REACH Affected, whereas the KY50VB101M8X11LL is REACH Unaffected.

Performance Consideration: The UHE1H101MPD exhibits higher ripple current capability at low frequency (388.5 mA @ 120 Hz versus 222 mA @ 120 Hz), while maintaining identical ripple current at high frequency (555 mA @ 100 kHz). This represents improved thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the UHE1H101MPD be used as a direct replacement for the KY50VB101M8X11LL?

A: Yes. The UHE1H101MPD meets all critical electrical and mechanical parameters. Both components have identical capacitance (100 µF), voltage rating (50 V), tolerance (±20%), lifetime (7000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), and physical dimensions. PCB layout compatibility is maintained due to identical lead spacing (0.138" / 3.50mm) and package dimensions (0.315" Dia / 8.00mm, height 0.453" / 11.50mm).

Q: What is the difference in ripple current between these parts?

A: At 120 Hz low frequency, the UHE1H101MPD provides 388.5 mA ripple current compared to 222 mA for the KY50VB101M8X11LL. At 100 kHz high frequency, both parts provide 555 mA ripple current. The higher low-frequency ripple current of the UHE1H101MPD indicates improved thermal performance in applications with significant low-frequency ripple content.

Q: Are there compliance differences between these parts?

A: Yes. The KY50VB101M8X11LL is RoHS non-compliant and REACH Unaffected. The UHE1H101MPD is ROHS3 compliant and REACH Affected. For applications subject to RoHS directives, the UHE1H101MPD provides regulatory compliance.

Q: What is the product status of these parts?

A: The KY50VB101M8X11LL is classified as obsolete. The UHE1H101MPD is classified as "Not For New Designs." Both parts have limited availability. For new production designs requiring extended component availability, alternative suppliers with active production status should be evaluated.

Q: Are the impedance values identical?

A: Yes. Both the KY50VB101M8X11LL and UHE1H101MPD have an impedance of 170 mOhms, ensuring equivalent electrical performance in circuit applications.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. Identical lead spacing (0.138" / 3.50mm), package type (radial, can), and physical dimensions (0.315" Dia / 8.00mm, height 0.453" / 11.50mm) ensure mechanical and electrical interchangeability in existing PCB designs without layout modifications.
