Substitute Part Grouping Explanation

Substitution eligibility for the EEU-TP1E221B is determined by strict equivalence across the following critical parameters: capacitance value (220 µF), rated voltage (25 V), tolerance (±20%), operating temperature range (-40°C ~ 135°C), lifetime specification (3000 Hrs @ 125°C), ripple current ratings (377 mA @ 120 Hz and 500 mA @ 100 kHz), physical dimensions (0.394" diameter, 0.551" maximum height, 0.197" lead spacing), mounting type (through hole), package configuration (radial can), series designation (TP-A), and compliance certifications (AEC-Q200, ROHS3). The identified substitute part EEU-TP1E221 maintains complete electrical and mechanical equivalence with the main part number, differing only in packaging format (bulk versus cut tape). This packaging variation does not affect component performance, electrical characteristics, or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both EEU-TP1E221B and EEU-TP1E221 are active production components from Panasonic Electronic Components with identical electrical performance and mechanical compatibility. Selection between these part numbers is determined by procurement and assembly requirements rather than technical performance. The EEU-TP1E221B in cut tape packaging is suitable for automated pick-and-place assembly operations. The EEU-TP1E221 in bulk packaging accommodates manual assembly processes or high-volume reel-based automation. Both variants maintain full AEC-Q200 automotive qualification and ROHS3 compliance, ensuring equivalent reliability and regulatory acceptance across automotive applications. Component selection should be based on assembly methodology and supply chain logistics rather than performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can EEU-TP1E221 replace EEU-TP1E221B in automotive applications?

A: Yes. Both part numbers are electrically and mechanically identical, maintaining the same 220 µF capacitance, 25 V rating, AEC-Q200 compliance, and physical dimensions. The difference is packaging format only. Substitution is valid for any application where the original part is specified.

Q: What is the difference between cut tape and bulk packaging?

A: Cut tape (CT) packaging supplies components on individual tape segments suitable for automated assembly equipment. Bulk packaging supplies loose components in larger quantities. Both formats contain identical components with no performance variation.

Q: Are both parts suitable for the full -40°C to 135°C temperature range?

A: Yes. Both EEU-TP1E221B and EEU-TP1E221 are rated for operation across the complete -40°C to 135°C temperature range with 3000-hour lifetime at 125°C.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both components carry AEC-Q200 automotive qualification and ROHS3 compliance certification, meeting equivalent regulatory and reliability standards for automotive applications.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Identical lead spacing (0.197" / 5.00 mm), physical dimensions (0.394" diameter, 0.551" maximum height), and through-hole mounting configuration ensure direct PCB compatibility between both part numbers.
