EEF-UD0J101CE Equivalent & Substitute Parts

Part Overview

The EEF-UD0J101CE is a 100 µF, 6.3 V aluminum polymer capacitor manufactured by Panasonic Electronic Components in the 2917 (7343 Metric) surface mount package. This part is classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and production continuity. The UD series represents an earlier generation of Panasonic's polymer capacitor lineup with a rated lifetime of 1000 hours at 105°C. Substitute parts must maintain electrical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEF-UD0J101CE is based on strict equivalence of the following electrical and mechanical parameters:

• Capacitance value: 100 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Component type: Aluminum Polymer (exact match required)

The substitute part EEF-CX0J101R meets all these criteria. While the CX series offers improved performance characteristics (lower ESR, extended lifetime, wider operating temperature range), these enhancements do not disqualify it as a direct substitute. The substitute maintains full electrical and mechanical compatibility with the original part specification.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0J101R is the direct substitute for the obsolete EEF-UD0J101CE. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications (100 µF, 6.3 V, ±20% tolerance) and mechanical form factor (2917 package, surface mount).

The substitute part is classified as Active, ensuring continued availability and manufacturing support. The EEF-CX0J101R carries RoHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

The CX series provides enhanced performance over the UD series through improved ESR characteristics (15 mOhm specified) and extended operational lifetime (2000 hours at 105°C versus 1000 hours). The wider operating temperature range (-55°C to 105°C) provides additional design margin compared to the original part (-40°C to 105°C).

Frequently Asked Questions (FAQ)

Q: Can EEF-CX0J101R be used as a direct replacement for EEF-UD0J101CE?

A: Yes. Both parts share identical capacitance (100 µF), voltage rating (6.3 V), tolerance (±20%), package (2917 Metric), and mounting type (surface mount). The substitute is electrically and mechanically compatible.

Q: What is the primary reason for substitution?

A: The EEF-UD0J101CE is classified as obsolete. The EEF-CX0J101R is an active product from the same manufacturer, ensuring long-term availability and supply chain continuity.

Q: Are there differences in physical dimensions?

A: Both parts use the 2917 (7343 Metric) package with identical land size (0.287" L x 0.169" W / 7.30mm x 4.30mm). The seated height differs: EEF-UD0J101CE is 0.118" (3.00mm) maximum, while EEF-CX0J101R is 0.075" (1.90mm) maximum. This reduced height of the substitute part does not affect compatibility and may provide PCB layout advantages.

Q: Does the substitute part meet current compliance standards?

A: Yes. The EEF-CX0J101R is RoHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: What is the packaging difference between the two parts?

A: The main part (EEF-UD0J101CE) packaging is not specified in available data. The substitute part (EEF-CX0J101R) is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.
