Substitute Part Grouping Explanation

The Nichicon UBW1E101MPD qualifies as a substitute for the UBW1C101MPD based on the following allowed substitution criteria:

Matching Parameters:

• Capacitance: 100 µF (identical)
• Tolerance: ±20% (identical)
• Operating Temperature Range: -55°C ~ 135°C (identical)
• Lifetime @ Temperature: 1000 Hrs @ 135°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial, Can (identical)
• Lead Spacing: 0.138" (4.60mm) (identical)
• Size / Dimension: 0.315" Dia (8.00mm) (identical)
• Height - Seated (Max): 0.531" (14.60mm) (identical)
• Series: UBW (identical)
• Manufacturer: Nichicon (identical)
• RoHS Status: ROHS3 Compliant (identical)

Upgrade Parameter:

• Voltage - Rated: 25 V (upgraded from 16 V)

The UBW1E101MPD operates at a higher voltage rating while maintaining all other electrical and mechanical specifications. This upgrade substitution is valid for circuits designed for 16 V operation, as the higher voltage rating provides additional safety margin without affecting form factor, thermal characteristics, or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the UBW1C101MPD and UBW1E101MPD maintain active product status with full ROHS3 compliance and REACH compliance. The UBW1E101MPD represents an upgrade substitution option, offering higher voltage rating (25 V versus 16 V) while preserving identical mechanical form factor and thermal performance specifications.

Selection between these parts depends on circuit voltage requirements. For applications operating at or below 16 V, either part is suitable. The UBW1E101MPD provides additional voltage margin and improved ripple current handling (250 mA @ 120 Hz and 500 mA @ 100 kHz versus 170 mA and 340 mA respectively) with lower impedance (130 mOhms versus 320 mOhms), making it the preferred choice when design flexibility permits.

Both parts are automotive-rated and suitable for through-hole PCB assembly with identical lead spacing and package dimensions, ensuring direct mechanical and electrical compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can UBW1E101MPD replace UBW1C101MPD in a 16 V circuit?

A: Yes. The UBW1E101MPD is rated for 25 V operation and is fully compatible with 16 V circuits. The higher voltage rating provides additional safety margin without affecting performance or mechanical fit.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical lead spacing (0.138" / 4.60mm), diameter (0.315" / 8.00mm), and maximum seated height (0.531" / 14.60mm). Direct PCB mounting compatibility is confirmed.

Q: What is the difference in ripple current handling?

A: The UBW1E101MPD handles higher ripple currents: 250 mA @ 120 Hz and 500 mA @ 100 kHz, compared to 170 mA and 340 mA for the UBW1C101MPD. This results from the lower impedance specification (130 mOhms versus 320 mOhms).

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both UBW1C101MPD and UBW1E101MPD are automotive-rated, ROHS3 compliant, and REACH affected. Both maintain 1000 hours lifetime rating at 135°C and operate across -55°C to 135°C temperature range.

Q: Is inventory availability a consideration for selection?

A: The UBW1E101MPD has higher inventory availability (3636 pcs) compared to UBW1C101MPD (1276 pcs), which may influence procurement decisions for high-volume applications.
