EEF-CD1C8R2R Equivalent & Substitute Parts

Part Overview

The EEF-CD1C8R2R is an 8.2 µF, 16 V aluminum polymer capacitor manufactured by Panasonic Electronic Components in the SP-Cap CD series. This surface mount component is designed for general purpose applications with a rated lifetime of 1000 hours at 105°C. The part is currently obsolete, making identification of suitable substitute components necessary for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitution of the EEF-CD1C8R2R is based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance value: 8.2 µF (exact match required)
Tolerance: ±20% (exact match required)
Type: Aluminum Polymer (exact match required)
Mounting: Surface Mount (exact match required)

Allowable Parameter Variations:

Voltage Rating: Equal to or greater than 16 V
ESR: Equal to or lower than 45 mOhm
Lifetime @ Temperature: Equal to or greater than 1000 Hrs @ 105°C
Operating Temperature Range: Must encompass or exceed -40°C ~ 105°C
Package / Case: Functionally equivalent surface mount packages acceptable

The substitute part PCV1H8R2MCL1GS meets these criteria with a higher voltage rating (50 V), lower ESR (81 mOhm), and extended lifetime (3000 Hrs @ 105°C), making it electrically compatible for applications requiring the EEF-CD1C8R2R.

Engineering Selection Recommendations

The PCV1H8R2MCL1GS from Nichicon is an active product suitable for replacing the obsolete EEF-CD1C8R2R. The substitute part maintains identical capacitance and tolerance specifications while providing enhanced electrical characteristics: a higher voltage rating (50 V vs. 16 V) and extended operational lifetime (3000 Hrs @ 105°C vs. 1000 Hrs @ 105°C).

The substitute part carries RoHS3 compliance and REACH compliance status, meeting current regulatory requirements. The higher voltage rating provides additional design margin and reliability for the application. The extended temperature range (-55°C ~ 105°C) offers broader operational flexibility compared to the original part.

Note that the substitute part features a different package configuration (Radial, Can - SMD vs. 2917 Metric) and higher ESR (81 mOhm vs. 45 mOhm). PCB layout modifications may be required to accommodate the different physical dimensions and land pattern. The reduced ripple current rating (800 mA vs. 1.3 A @ 100 kHz) should be evaluated against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the PCV1H8R2MCL1GS directly replace the EEF-CD1C8R2R without circuit modifications?

A: Electrical substitution is valid based on capacitance, tolerance, and voltage rating compatibility. However, physical package differences require PCB layout evaluation. The substitute part uses a Radial, Can - SMD package versus the original 2917 (7343 Metric) package, necessitating land pattern and mounting area assessment.

Q: What is the impact of the higher voltage rating (50 V vs. 16 V) on circuit performance?

A: A higher voltage rating does not negatively affect circuit operation in applications designed for 16 V. The substitute part provides additional voltage margin and typically improves reliability and lifetime in the application.

Q: Does the higher ESR (81 mOhm vs. 45 mOhm) affect circuit functionality?

A: ESR impact depends on application-specific ripple current and frequency requirements. The substitute part's ESR is within acceptable ranges for general purpose applications. High-frequency or high-ripple-current circuits should be evaluated against the reduced ripple current specification (800 mA vs. 1.3 A @ 100 kHz).

Q: Are there compliance or certification differences between the two parts?

A: The EEF-CD1C8R2R carries MSL 3 rating. The PCV1H8R2MCL1GS is RoHS3 and REACH compliant, meeting current regulatory standards. Both parts share the same ECCN and HTSUS classifications.

Q: What packaging format is the substitute part supplied in?

A: The PCV1H8R2MCL1GS is supplied in Tape & Reel (TR) format, standard for surface mount production environments.
