Equivalent & Substitute Parts for UPW1A102MPD

Part Overview

The UPW1A102MPD is a 1000 µF, 10 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product portfolio. The part delivers 5000 hours of operational life at 105°C and is suitable for general-purpose applications requiring stable capacitance and ripple current handling in through-hole mounting configurations.

Equivalent and substitute parts are necessary when the UPW1A102MPD reaches end-of-life status, when inventory becomes unavailable, or when design requirements necessitate alternative performance characteristics such as improved ripple current ratings, reduced impedance, or automotive-grade certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the UPW1A102MPD is determined by strict equivalence across the following parameters:

Primary Equivalence Criteria:

Capacitance: 1000 µF (exact match required)
Voltage Rating: 10 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)

Secondary Compatibility Parameters:

Operating Temperature Range: -55°C ~ 105°C (must meet or exceed)
Lifetime @ 105°C: 5000 Hrs minimum (equal or greater acceptable)
Impedance: 68 mOhms (lower values acceptable; higher values require application verification)
Ripple Current Ratings: Must meet or exceed specified values at rated frequencies

Dimensional Constraints:

Diameter: 0.394" (10.00mm) (exact match required for PCB fit)
Height: 0.630" (16.00mm) (exact match required for clearance; greater heights require board layout verification)

Substitute parts are grouped into three categories: direct equivalents (identical across all parameters), compatible substitutes (meet all primary criteria with acceptable secondary variations), and conditional substitutes (require application-specific verification due to dimensional or performance differences).

Engineering Selection Recommendations

Direct Equivalent (Dimensional and Electrical Match):

EEU-FC1A102 from Panasonic Electronic Components is the primary direct equivalent. It matches the UPW1A102MPD across all critical parameters: 1000 µF capacitance, 10 V rating, ±20% tolerance, 0.394" diameter, 0.197" lead spacing, 68 mOhms impedance, and identical ripple current specifications. The EEU-FC1A102 carries Active product status and AEC-Q200 automotive qualification, providing enhanced long-term availability and reliability assurance. The lifetime specification is 3000 hours at 105°C, which is lower than the UPW1A102MPD's 5000 hours; this difference is acceptable for applications not requiring extended thermal endurance.

Compatible Substitutes (Dimensional Constraints):

EEU-FC1A102B from Panasonic is functionally equivalent to EEU-FC1A102 with identical electrical performance and Active status. The height specification is 0.669" (17.00mm) compared to the UPW1A102MPD's 0.630" (16.00mm), requiring verification of PCB clearance in the target application.

ELXZ100ELL102MJ16S from Chemi-Con maintains the same footprint as the UPW1A102MPD (0.394" diameter, 0.197" lead spacing) with matching impedance and ripple current ratings. This part offers 5000 hours lifetime at 105°C and carries AEC-Q200 certification. Height is 0.689" (17.50mm), requiring clearance verification. The lower ripple current at 120 Hz (630 mA versus 787.5 mA) is acceptable for most applications.

Conditional Substitutes (Dimensional Mismatch):

UPJ1A102MHD6, UPM1A102MHD6, and EEU-FC1A102L feature different lead spacing (0.138" versus 0.197") and/or diameter specifications (0.315" or 0.492" versus 0.394"), requiring PCB redesign or adapter solutions. These parts are not recommended for direct board-level substitution without layout modification.

UPS1A102MPD and UPW1A102MPD6 deliver reduced lifetime specifications (2000 and 3000 hours respectively) and are suitable only for applications with lower thermal stress requirements.

Compliance and Availability:

For new designs or long-term production requirements, EEU-FC1A102 or ELXZ100ELL102MJ16S are preferred due to Active product status and AEC-Q200 certification. All Nichicon UPW, UPJ, UPM, and UPS series parts are classified as Not For New Designs and should be considered end-of-life alternatives only.

Frequently Asked Questions (FAQ)

Q: Can UPJ1A102MHD6 replace UPW1A102MPD directly on the PCB?

A: No. UPJ1A102MHD6 has a diameter of 0.492" (12.50mm) compared to the UPW1A102MPD's 0.394" (10.00mm). This dimensional difference prevents direct board-level substitution. PCB layout modification is required.

Q: What is the difference between EEU-FC1A102 and EEU-FC1A102B?

A: Both parts are electrically identical with matching capacitance, voltage, tolerance, impedance, and ripple current specifications. The primary difference is packaging: EEU-FC1A102 is supplied in Bulk packaging, while EEU-FC1A102B is supplied in Cut Tape (CT) format. Height differs slightly: 0.630" (16.00mm) for EEU-FC1A102 versus 0.669" (17.00mm) for EEU-FC1A102B. For PCB clearance-critical applications, EEU-FC1A102 is preferred.

Q: Why does ELXZ100ELL102MJ16S show lower ripple current at 120 Hz?

A: ELXZ100ELL102MJ16S is specified at 630 mA @ 120 Hz compared to the UPW1A102MPD's 787.5 mA. This reflects different internal construction and thermal characteristics. The part remains suitable for applications where the actual ripple current demand does not exceed 630 mA at 120 Hz. High-frequency ripple current (1.05 A @ 100 kHz) is equivalent.

Q: Is UPM1A102MPD suitable as a substitute despite its greater height?

A: UPM1A102MPD has a height of 0.866" (22.00mm) versus the UPW1A102MPD's 0.630" (16.00mm). This 0.236" increase requires PCB clearance verification. The part offers superior electrical performance with 60 mOhms impedance and AEC-Q200 certification. Substitution is conditional on board layout accommodation.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive-grade reliability standard. Parts carrying this certification (EEU-FC1A102, EEU-FC1A102B, EEU-FC1A102L, ELXZ100ELL102MJ16S, UPM1A102MHD6, UPM1A102MPD) have undergone enhanced qualification testing for automotive applications. For non-automotive applications, this certification provides additional assurance of manufacturing consistency and long-term reliability.

Q: Can UPW1A102MPD6 be used as a direct replacement?

A: No. UPW1A102MPD6 has different lead spacing (0.138" versus 0.197") and diameter (0.315" versus 0.394"), preventing direct PCB substitution. Additionally, it specifies only 3000 hours lifetime at 105°C compared to the UPW1A102MPD's 5000 hours.

Q: Which substitute offers the best long-term availability?

A: EEU-FC1A102 and ELXZ100ELL102MJ16S both carry Active product status, indicating ongoing manufacturing and distribution. EEU-FC1A102 is preferred for applications requiring exact dimensional match (0.630" height). ELXZ100ELL102MJ16S is preferred for applications requiring 5000-hour lifetime specification at 105°C.
