Substitute Part Grouping Explanation

Substitution of the UPW1H121MPD1TA is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 120 µF (exact match required)
• Voltage rating: 50 V (minimum acceptable)
• Tolerance: ±20% (matching specification)
• Polarization: Polar (radial aluminum electrolytic)
• Physical dimensions: 0.315" Dia × 0.650" Height (board layout compatibility)
• Lead spacing: 0.138" (4.60mm) (PCB footprint compatibility)
• Mounting type: Through Hole (assembly process compatibility)
• Operating temperature range: -55°C ~ 105°C (thermal envelope)
• Lifetime rating: 2000 Hrs @ 105°C (reliability requirement)

The substitute part EEU-FC1H121LJ meets all these criteria and is qualified as a direct equivalent.

Frequently Asked Questions (FAQ)

Q: Can the EEU-FC1H121LJ be used as a direct replacement for the UPW1H121MPD1TA?

A: Yes. Both parts share identical capacitance (120 µF), voltage rating (50 V), tolerance (±20%), physical dimensions, lead spacing, and thermal specifications. No circuit modifications or PCB layout changes are required.

Q: Are there any packaging differences between these parts?

A: The UPW1H121MPD1TA is supplied in Cut Tape (CT) packaging, while the EEU-FC1H121LJ is supplied in Tape & Box (TB) packaging. Both are through-hole radial components with identical footprints.

Q: What is the significance of the AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive qualification standard. The EEU-FC1H121LJ meets this specification, making it suitable for automotive applications. The original UPW1H121MPD1TA does not carry this designation but remains suitable for general-purpose applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the UPW1H121MPD1TA and EEU-FC1H121LJ are ROHS3 compliant.

Q: What is the difference in product status between these parts?

A: The UPW1H121MPD1TA carries "Not For New Designs" status, indicating it is in end-of-life phase. The EEU-FC1H121LJ carries "Active" status, indicating it is in current production and recommended for new designs.
