Substitute Part Grouping Explanation

Substitution for the UPS2A2R2MDD is determined by strict adherence to the following electrical and mechanical parameters:

Capacitance: 2.2 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.079" (2.00 mm) (exact match required)
Package / Case: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)

All substitute parts listed below meet these core parameters. Variations in ripple current ratings, impedance, height, and lifetime at temperature are permitted within the scope of general-purpose and automotive applications, provided the part maintains compatibility with the specified electrical and mechanical envelope.

Engineering Selection Recommendations

Nichicon UPW2A2R2MDD, UPJ2A2R2MDD, and UPM2A2R2MDD are direct Nichicon series alternatives. UPM2A2R2MDD carries AEC-Q200 automotive qualification and is suitable for automotive applications. All three Nichicon alternatives maintain 2000-hour lifetime at 105°C and are ROHS3 compliant.

Panasonic EEU-FC2A2R2 is an active product with AEC-Q200 automotive qualification. It provides lower impedance (5.4 Ω) but has a reduced lifetime rating of 1000 hours at 105°C compared to the original part. This part is suitable for applications where active product availability and automotive compliance are prioritized.

Cornell Dubilier 225KXM100M is an active product maintaining 2000-hour lifetime at 105°C. It has higher impedance (18.36 Ω) and is ROHS3 compliant. This part is suitable for general-purpose applications where active product status is required.

Frequently Asked Questions (FAQ)

Q: Can UPW2A2R2MDD replace UPS2A2R2MDD directly?

A: Yes. UPW2A2R2MDD meets all core electrical and mechanical parameters. The height difference (0.433" vs. 0.492") is within acceptable tolerance for through-hole radial can packages and does not affect electrical performance or circuit board layout compatibility in standard applications.

Q: What is the difference between Nichicon UPJ2A2R2MDD and UPM2A2R2MDD?

A: Both parts share identical electrical specifications (2.2 µF, 100 V, ±20%, 2000 Hrs @ 105°C). UPM2A2R2MDD carries AEC-Q200 automotive qualification and is rated for automotive applications. UPJ2A2R2MDD is rated for general-purpose applications. Height and impedance are equivalent between the two.

Q: Why does EEU-FC2A2R2 have a lower lifetime rating?

A: EEU-FC2A2R2 is rated for 1000 hours at 105°C, compared to 2000 hours for the original UPS2A2R2MDD. This is a design characteristic of the Panasonic FC series. For applications requiring extended thermal life, Nichicon or Cornell Dubilier alternatives with 2000-hour ratings are recommended.

Q: Is EEU-FC2A2R2 suitable for automotive applications?

A: Yes. EEU-FC2A2R2 carries AEC-Q200 automotive qualification and is rated for automotive applications. It is an active product with current availability.

Q: Can 225KXM100M be used in place of UPS2A2R2MDD?

A: Yes. 225KXM100M meets all core electrical and mechanical parameters and maintains 2000-hour lifetime at 105°C. The higher impedance (18.36 Ω) is a design characteristic of the Cornell Dubilier KXM series and does not prevent direct substitution in standard applications. Verify impedance compatibility in ripple-current-sensitive circuits.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original UPS2A2R2MDD.

Q: What is the lead spacing tolerance for these parts?

A: All parts maintain 0.079" (2.00 mm) lead spacing, ensuring compatibility with existing through-hole PCB layouts designed for the UPS2A2R2MDD.
