Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEU-TA1J101 is permissible when the replacement part maintains the following critical parameters:

• Capacitance: 100 µF (exact match required)
• Tolerance: ±20% (matching tolerance specification)
• Polarization: Polar (same polarity requirement)
• Mounting Type: Through Hole (same PCB assembly method)
• Package / Case: Radial, Can (same physical form factor)
• Lead Spacing: 0.197" (5.00mm) (identical pin pitch for PCB compatibility)
• Size / Dimension: 0.394" Dia (10.00mm) (same diameter for board layout)
• Height - Seated (Max): 0.866" (22.00mm) (same height for clearance compatibility)
• Operating Temperature Range: -40°C ~ 125°C (minimum required range)

The substitute part UBT1K101MPD8 (Nichicon) meets all mechanical and electrical compatibility criteria. The rated voltage of 80 V on the substitute exceeds the 63 V requirement, providing additional voltage margin. The extended lifetime rating of 3000 hours at 125°C compared to 2000 hours represents an operational improvement.

Parameter Comparison

Engineering Selection Recommendations

Both the EEU-TA1J101 and UBT1K101MPD8 are Active product status components with ROHS3 compliance and identical export classification (EAR99). The UBT1K101MPD8 substitute offers a higher rated voltage (80 V versus 63 V) and extended thermal lifetime (3000 hours versus 2000 hours at 125°C), making it suitable for applications requiring enhanced reliability margins. Both components share identical mechanical dimensions and lead spacing, ensuring direct PCB compatibility without layout modifications. Selection between these parts should be based on inventory availability, cost considerations, and application-specific thermal or voltage margin requirements.

Frequently Asked Questions (FAQ)

Q: Can UBT1K101MPD8 be used as a direct replacement for EEU-TA1J101?

A: Yes. Both components share identical capacitance (100 µF), tolerance (±20%), polarization (Polar), lead spacing (5.00mm), physical dimensions (10.00mm diameter, 22.00mm height), and mounting type (Through Hole, Radial Can). PCB layout and assembly procedures require no modification.

Q: What are the differences between these two parts?

A: The primary differences are rated voltage (63 V versus 80 V), thermal lifetime (2000 hours versus 3000 hours at 125°C), ripple current ratings at specific frequencies, and impedance characteristics. The substitute part provides higher voltage and thermal ratings.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and classified under identical ECCN (EAR99) and HTSUS (8532.22.0020) codes. No compliance barriers exist for substitution.

Q: Does the higher voltage rating of the substitute affect circuit operation?

A: No. A component rated for higher voltage than required operates safely within the circuit. The 80 V rating of UBT1K101MPD8 provides additional voltage margin when used in applications designed for 63 V operation.

Q: Are the mechanical packages identical?

A: Yes. Both components are radial, can-style aluminum electrolytic capacitors with identical lead spacing (5.00mm), diameter (10.00mm), and maximum seated height (22.00mm). No PCB footprint changes are required.
