Substitute Part Grouping Explanation

Substitution eligibility for the UHE1V102MHD1TO is determined by strict equivalence across the following parameters:

Capacitance: 1000 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 10,000 Hrs @ 105°C (exact match required)
Operating Temperature: -40°C ~ 105°C (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Package Type: Radial, Can (exact match required)
Mounting: Through Hole (exact match required)
Polarization: Polar (exact match required)
RoHS Compliance: ROHS3 Compliant (required)

All substitute parts listed meet these criteria. Variations in physical dimensions (diameter and height), ripple current ratings, impedance, and product status are noted but do not disqualify substitution when core electrical parameters align.

Engineering Selection Recommendations

For Active Production Lines: EEU-FR1V102B (Panasonic) and EEU-EB1V102B (Panasonic) are recommended as primary substitutes due to their Active product status. Both maintain full electrical equivalence and ROHS3 compliance. EEU-FR1V102B offers superior ripple current performance (1.95 A @ 120 Hz, 2.6 A @ 100 kHz) and lower impedance (18 mOhms) compared to the original part, with a more compact height profile (0.866" vs. 1.063"). EEU-EB1V102B provides identical physical dimensions to the original but with reduced ripple current capacity, suitable for lower-stress applications.

For Continued Support of Legacy Designs: 860040578014 (Würth Elektronik) maintains Active status with electrical performance closely aligned to the original UHE1V102MHD1TO. Slight dimensional variation in diameter (0.512" vs. 0.492") requires PCB layout verification but does not affect electrical substitution.

For Parametric Equivalence Only: 35YXF1000MEFCG412.5X25 (Rubycon) carries "Not For New Designs" status identical to the original part. While electrically equivalent, this part exhibits lower ripple current ratings (1.238 A @ 120 Hz, 1.65 A @ 100 kHz) and higher impedance (48 mOhms), making it suitable only for direct replacement in existing designs where performance margins are confirmed.

Frequently Asked Questions (FAQ)

Q: Can EEU-FR1V102B be used as a direct replacement for UHE1V102MHD1TO on existing PCBs?

A: Yes, with layout verification. Both parts share identical lead spacing (5.00 mm) and capacitance/voltage ratings. However, EEU-FR1V102B has a reduced height (0.866" vs. 1.063"), which may affect clearance in confined spaces. Verify PCB silkscreen dimensions and component placement before substitution.

Q: What is the difference between Cut Tape (CT) and Tape & Box (TB) packaging?

A: Cut Tape packaging supplies individual components on carrier tape suitable for automated pick-and-place assembly. Tape & Box packaging includes the same tape format but with additional protective boxing for storage and handling. Both formats are electrically identical; packaging choice depends on assembly process requirements and inventory management.

Q: Why does EEU-EB1V102B show significantly lower ripple current ratings?

A: EEU-EB1V102B is designed for lower-stress applications and exhibits reduced ripple current capacity (586 mA @ 120 Hz vs. 1.673 A for the original). This part is suitable for circuits where ripple current demands are below 600 mA; applications requiring higher ripple current handling should use EEU-FR1V102B or 860040578014.

Q: Is REACH compliance a factor in selecting substitutes?

A: REACH compliance status indicates regulatory standing in European markets. The original UHE1V102MHD1TO is REACH Affected, while all substitute parts are REACH Unaffected, providing improved regulatory positioning for new designs and long-term supply chain stability.

Q: Can 35YXF1000MEFCG412.5X25 replace UHE1V102MHD1TO in high-ripple-current applications?

A: No. The Rubycon part exhibits lower ripple current capacity (1.238 A @ 120 Hz vs. 1.673 A) and higher impedance (48 mOhms vs. 27 mOhms). Use this part only for direct replacement in existing designs where ripple current stress is confirmed below 1.2 A at 120 Hz.
