Substitute Part Grouping Explanation

Substitution of the UCY2C151MHD91TO is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 150 µF (exact match required)
• Voltage rating: 160 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 12000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Ripple current ratings: 760 mA @ 120 Hz and 1.52 A @ 100 kHz (exact match required)
• Lead spacing: 0.197" (5.00mm) (exact match required)
• Package type: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Compliance certifications: ROHS3 and REACH (exact match required)

The UCY2C151MHD9TO meets all substitution criteria. The primary difference is packaging configuration: the main part uses standard packaging while the substitute uses Cut Tape (CT) packaging. Both parts are manufactured by Nichicon within the UCY series and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the UCY2C151MHD91TO and UCY2C151MHD9TO are Active products from Nichicon's UCY series. Selection between these parts should be based on procurement and supply chain requirements rather than electrical or mechanical performance differences. Both parts maintain full ROHS3 compliance and REACH regulatory status. The substitute part UCY2C151MHD9TO is available in Cut Tape packaging, which may be advantageous for automated assembly processes or specific inventory management requirements. Electrical performance, thermal characteristics, and physical dimensions are identical across both part numbers, ensuring direct functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can UCY2C151MHD9TO be used as a direct replacement for UCY2C151MHD91TO?

A: Yes. Both parts are electrically and mechanically identical. They share the same capacitance (150 µF), voltage rating (160 V), tolerance (±20%), lifetime specification (12000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), ripple current ratings, lead spacing (5.00mm), physical dimensions, and compliance certifications. The only difference is packaging format.

Q: What is the difference between the packaging configurations?

A: The UCY2C151MHD91TO uses standard packaging, while the UCY2C151MHD9TO is supplied in Cut Tape (CT) format. Both configurations contain identical components with the same electrical and mechanical specifications. Cut Tape packaging is typically used for automated pick-and-place assembly operations.

Q: Are both parts compliant with current regulations?

A: Yes. Both the UCY2C151MHD91TO and UCY2C151MHD9TO are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements for electronic components.

Q: Will substituting these parts require PCB layout changes?

A: No. Both parts have identical lead spacing (0.197" / 5.00mm), physical dimensions (0.492" diameter / 12.50mm), and height (1.043" / 26.50mm). PCB footprints and mounting requirements remain unchanged.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts are rated for identical operating temperatures (-40°C ~ 105°C) and maintain the same lifetime specification of 12000 hours at 105°C. Ripple current handling at both low frequency (760 mA @ 120 Hz) and high frequency (1.52 A @ 100 kHz) is identical.
