Substitute Part Grouping Explanation

The EEU-TP1E332SB qualifies as a direct substitute based on the following criteria:

Matching parameters across both parts:

• Capacitance: 3300 µF (identical)
• Tolerance: ±20% (identical)
• Lead Spacing: 0.295" (7.50 mm) (identical)
• Physical Dimensions: 0.709" Dia (18.00 mm), Height 1.063" (27.00 mm) (identical)
• Package / Case: Radial, Can (identical)
• Mounting Type: Through Hole (identical)
• Polarization: Polar (identical)

The substitute part EEU-TP1E332SB provides enhanced electrical performance with a higher rated voltage (25 V vs. 16 V), extended lifetime (5000 Hrs @ 125°C vs. 2000 Hrs @ 125°C), and expanded operating temperature range (-40°C ~ 135°C vs. -40°C ~ 125°C). These characteristics make it suitable for applications requiring improved reliability margins or automotive-grade specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the EEU-TA1C332SB and EEU-TP1E332SB are active production parts with ROHS3 compliance. The EEU-TP1E332SB carries AEC-Q200 automotive qualification, indicating suitability for automotive applications. Selection between these parts should be based on application voltage requirements and reliability specifications. The substitute part's higher voltage rating (25 V) and extended lifetime (5000 Hrs @ 125°C) provide additional design margin for applications operating at or near the 16 V rating of the main part. Both parts share identical physical footprints and lead spacing, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can EEU-TP1E332SB replace EEU-TA1C332SB in existing designs?

A: Yes. Both parts have identical capacitance (3300 µF), tolerance (±20%), physical dimensions, lead spacing (0.295" / 7.50 mm), and mounting configuration (through-hole radial). The substitute part is electrically and mechanically compatible.

Q: What are the key differences between these parts?

A: The EEU-TP1E332SB has a higher rated voltage (25 V vs. 16 V), extended lifetime (5000 Hrs @ 125°C vs. 2000 Hrs @ 125°C), wider operating temperature range (-40°C ~ 135°C vs. -40°C ~ 125°C), and AEC-Q200 automotive qualification. Ripple current capability at 120 Hz is also higher (2.368 A vs. 1.976 A).

Q: Are there packaging differences?

A: Yes. The main part is supplied in Tape & Box (TB) packaging, while the substitute is supplied in Cut Tape (CT) packaging. This affects order quantities and handling but does not impact component performance or PCB compatibility.

Q: Is the substitute part suitable for automotive applications?

A: The EEU-TP1E332SB carries AEC-Q200 qualification, making it suitable for automotive applications. The main part does not have this certification.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both parts have identical lead spacing (0.295" / 7.50 mm), diameter (0.709" / 18.00 mm), and height (1.063" / 27.00 mm), ensuring direct PCB compatibility without layout modifications.
