Substitute Part Grouping Explanation

Substitution for the UPV1V270MFD is determined by strict electrical and mechanical compatibility criteria:

Electrical Parameters (Must Match):

Capacitance: 27 µF
Tolerance: ±20%
Voltage Rating: 35 V
Operating Temperature Range: -55°C to 105°C
Polarization: Polar (aluminum electrolytic)

Mechanical Parameters (Must Match or Be Compatible):

Lead Spacing: 0.079" (2.00 mm) — primary constraint for PCB layout
Size / Dimension: 0.197" Dia (5.00 mm) — radial can diameter
Height - Seated (Max): 0.492" (12.50 mm) — maximum allowable height
Mounting Type: Through Hole
Package / Case: Radial, Can

Lifetime Consideration: The UPV1V270MFD specifies 5000 hours at 105°C. Substitute parts with lower lifetime ratings (1000 or 2000 hours) remain electrically compatible but may require thermal management review in high-temperature applications.

All identified substitutes meet the core electrical specifications and mechanical form factor requirements. Panasonic EEU-FC and EEA-FC series parts are active products with AEC-Q200 automotive qualification. Nichicon UPM and UPW series are obsolete but remain in stock. Chemi-Con ELXY series offers active product status with automotive qualification.

Engineering Selection Recommendations

Direct Mechanical Compatibility (Preferred):

For applications requiring minimal PCB layout modification, select parts with matching lead spacing (0.079" / 2.00 mm) and compatible height:

EEU-FC1V270 (Panasonic): Active product status, AEC-Q200 automotive qualification, 1000-hour lifetime at 105°C. Height 0.472" (12.00 mm) fits within the original 0.492" (12.50 mm) constraint. Impedance 800 mOhm.
ELXY350ELL270MEB5D (Chemi-Con): Active product status, AEC-Q200 automotive qualification, 2000-hour lifetime at 105°C. Height 0.512" (13.00 mm) exceeds original specification by 0.020" but maintains electrical compatibility. Impedance 750 mOhm.
UPM1V270MDD (Nichicon): Obsolete status but in stock (2697 pcs). Matches original height 0.492" (12.50 mm) exactly. AEC-Q200 automotive qualification. 2000-hour lifetime at 105°C. Impedance 600 mOhm.

Alternative Lead Spacing Options:

If PCB redesign is acceptable, Panasonic EEA-FC1V270H offers the most compact form factor (0.315" height, 8.00 mm) with active product status and AEC-Q200 qualification, though it requires 0.098" (2.50 mm) lead spacing modification.

Lifetime Consideration:

The original UPV1V270MFD specifies 5000 hours at 105°C. All identified substitutes provide lower lifetime ratings (1000–2000 hours). For applications with extended thermal stress, prioritize ELXY350ELL270MEB5D or UPM1V270MDD (both 2000 hours) over Panasonic EEU-FC or EEA-FC series (1000 hours).

Product Status Priority:

For new designs, prioritize active products: Panasonic EEU-FC1V270, EEA-FC1V270H, or Chemi-Con ELXY350ELL270MEB5D. For legacy production support, Nichicon UPM1V270MDD and UPW1V270MDD remain available despite obsolete classification.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different lead spacing on my existing PCB?

A: No. Lead spacing is a fixed mechanical constraint determined by PCB trace routing and component footprint. Changing lead spacing requires PCB redesign. If your design uses 0.079" (2.00 mm) spacing, select only parts with matching spacing: UPV1V270MFD, UPM1V270MDD, UPW1V270MDD, EEU-FC1V270, or ELXY350ELL270MEB5D.

Q: What is the impact of lower lifetime ratings on substitute parts?

A: Lifetime rating indicates hours of operation at maximum rated temperature (105°C) before capacitance degradation reaches 80% of initial value. The original UPV1V270MFD specifies 5000 hours; most substitutes provide 1000–2000 hours. In applications with continuous high-temperature operation, lower lifetime may require thermal management review or more frequent replacement intervals. For room-temperature or moderate-temperature applications, this difference is negligible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitutes carry ROHS3 Compliant status, matching the original UPV1V270MFD specification.

Q: Which substitute offers the best active product status and automotive qualification?

A: Panasonic EEU-FC1V270 and Chemi-Con ELXY350ELL270MEB5D both carry active product status and AEC-Q200 automotive qualification. EEU-FC1V270 matches the original lead spacing (0.079" / 2.00 mm) and height (0.472" / 12.00 mm) most closely. ELXY350ELL270MEB5D provides longer lifetime (2000 hours vs. 1000 hours) but exceeds original height by 0.020".

Q: Can I substitute a part with different capacitance or voltage rating?

A: No. Capacitance and voltage rating are electrical parameters that determine circuit behavior. Substitution requires exact matching: 27 µF capacitance and 35 V voltage rating. Deviating from these values will alter circuit performance and may cause malfunction or component failure.

Q: What does impedance variation mean for my application?

A: Impedance affects high-frequency filtering performance and ripple current handling. The original UPV1V270MFD specifies 1 Ohm impedance; substitutes range from 450 mOhm to 800 mOhm. Lower impedance (Panasonic EEA-FC series at 450 mOhm) provides superior high-frequency filtering. Higher impedance (Panasonic EEU-FC series at 800 mOhm) is acceptable for general-purpose applications but may reduce filtering effectiveness in noise-sensitive circuits.
