Substitute Part Grouping Explanation

Substitution of the UPJ1E102MHD1TO is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Allowable Variation Parameters:

Voltage Rating: 25 V or higher (substitutes rated at 35 V are acceptable as they provide equal or greater voltage margin)
Operating Temperature Range: -55°C ~ 105°C or wider (substitutes with extended upper temperature limits are acceptable)
Lifetime @ Temperature: 5000 Hrs @ 105°C or longer (extended lifetime is acceptable)
Physical Dimensions: Minor variations in diameter and height are acceptable if lead spacing and mounting footprint remain compatible

Substitute parts are grouped into two categories:

Category 1 - Parametric Equivalents (Same Voltage Rating): Parts maintaining the 25 V voltage rating with identical or superior electrical characteristics.

Category 2 - Voltage Upgrades (Higher Voltage Rating): Parts rated at 35 V, providing enhanced voltage margin while maintaining all other critical parameters. These are suitable for direct substitution in applications where the original 25 V rating is not a limiting constraint.

Engineering Selection Recommendations

Direct Parametric Equivalent: UPM1E102MHD1TO maintains identical voltage rating (25 V) and electrical specifications as the UPJ1E102MHD1TO. This part is suitable for direct substitution in applications requiring the same voltage margin. The UPM series includes AEC-Q200 automotive qualification, making it appropriate for automotive applications. However, this part is also classified as "Not For New Designs."

Voltage-Upgraded Substitutes (35 V Rating): The following parts provide voltage upgrade capability while maintaining mechanical compatibility and core electrical parameters:

UPW1V102MHD1TO (Nichicon): Offers 35 V rating with extended lifetime (7000 Hrs @ 105°C) and lower impedance (30 mOhms). Classified as "Not For New Designs."
EEU-FC1V102B (Panasonic): Provides 35 V rating with AEC-Q200 automotive qualification and active product status. Impedance is 30 mOhms. This part is actively supported and suitable for new designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute UPJ1E102MHD1TO with a 35 V rated capacitor? A: Yes. A 35 V rated capacitor with identical capacitance (1000 µF), tolerance (±20%), lead spacing (5.00 mm), and package type (radial, through-hole) is a valid substitute. The higher voltage rating provides additional safety margin and does not negatively impact circuit performance in applications designed for 25 V operation.

Q: What is the difference between the Nichicon UPW1V102MHD1TO and UPM1E102MHD1TO? A: UPW1V102MHD1TO is rated at 35 V with 7000 Hrs lifetime @ 105°C and 30 mOhms impedance. UPM1E102MHD1TO maintains the original 25 V rating with 5000 Hrs lifetime @ 105°C and 36 mOhms impedance. Both are Nichicon products classified as "Not For New Designs."

Q: Why do some substitute parts have different physical dimensions? A: Würth Elektronik parts (860080578021 and 860160578032) have a diameter of 0.512" (13.00 mm) compared to the original 0.492" (12.50 mm). Lead spacing remains identical at 5.00 mm. PCB layout must be verified to confirm adequate clearance for the slightly larger diameter before substitution.

Q: Which substitute parts are suitable for automotive applications? A: EEU-FC1V102B (Panasonic), MAL214630102E3 (Vishay), and both Würth Elektronik parts (860080578021 and 860160578032) include AEC-Q200 automotive qualification. These parts are appropriate for automotive circuit designs.

Q: What does "Not For New Designs" mean? A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. Existing inventory may remain available, but long-term supply is not guaranteed. For new designs, select from parts with "Active" product status.

Q: How do impedance differences affect circuit performance? A: Lower impedance (measured in mOhms) indicates better high-frequency performance and lower voltage ripple. Würth 860080578021 offers the lowest impedance at 19 mOhms, while 860160578032 has higher impedance at 60 mOhms. Selection depends on specific ripple current and frequency requirements of the application.

Q: Can I use MAL214630102E3 in applications requiring -55°C ~ 105°C operation? A: Yes. MAL214630102E3 is rated for -55°C ~ 125°C, which exceeds the original -55°C ~ 105°C requirement. The extended upper temperature limit provides additional operational margin.
