EEF-SX0G820R Equivalent & Substitute Parts

Part Overview

The EEF-SX0G820R is an 82 µF, 4 V aluminum polymer capacitor manufactured by Panasonic Electronic Components in the SP-Cap SX series. This surface mount component is housed in a 2917 (7343 Metric) package with a rated lifetime of 2000 hours at 105°C and an equivalent series resistance (ESR) of 9 mOhm. The part is marked as "Not For New Designs," indicating it has been superseded. Identifying equivalent substitute parts is necessary for design continuity, inventory management, and ensuring component availability for existing applications and legacy system support.

Substitute Part Grouping Explanation

Substitution of the EEF-SX0G820R is determined by strict equivalence across the following critical parameters:

Capacitance value: 82 µF (exact match required)
Voltage rating: 4 V (exact match required)
Capacitor type: Aluminum Polymer (exact match required)
Tolerance: ±20% (exact match required)
ESR: 9 mOhm (exact match required)
Lifetime rating: 2000 Hrs @ 105°C (exact match required)
Operating temperature range: -55°C ~ 105°C (exact match required)
Package / Case: 2917 (7343 Metric) (exact match required)
Mounting type: Surface Mount (exact match required)
Physical dimensions: 0.287" L x 0.169" W x 0.079" H max (exact match required)

The EEF-SX0G820ER meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is packaging format: the EEF-SX0G820R is supplied in Tape & Reel (TR) format, while the EEF-SX0G820ER is supplied in Cut Tape (CT) format. Both parts share identical electrical and mechanical specifications within the SP-Cap SX series.

Engineering Selection Recommendations

The EEF-SX0G820ER is the direct parametric equivalent to the EEF-SX0G820R. Both parts are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements. The EEF-SX0G820ER carries an "Active" product status, whereas the EEF-SX0G820R is designated "Not For New Designs." For applications requiring component replacement or new procurement, the EEF-SX0G820ER is the appropriate selection within the SP-Cap SX series. The substitution is valid for all electrical and mechanical applications where the main part was originally specified, provided that the packaging format change from Tape & Reel to Cut Tape is compatible with the assembly process.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0G820ER be used as a direct replacement for the EEF-SX0G820R?

A: Yes. The EEF-SX0G820ER is a parametric equivalent with identical electrical specifications (82 µF, 4 V, 9 mOhm ESR, 2000 Hrs @ 105°C) and mechanical dimensions (2917 package, 7.30mm x 4.30mm x 2.00mm). The only difference is the packaging format: Cut Tape (CT) versus Tape & Reel (TR). Compatibility depends on whether your assembly process can accommodate Cut Tape packaging.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, typically used for lower-volume assembly or manual placement. Both formats contain the same component with identical specifications.

Q: Why is the EEF-SX0G820R marked "Not For New Designs"?

A: This designation indicates the part has been superseded by newer alternatives within the product line. The EEF-SX0G820ER, marked as "Active," is the current production equivalent and is recommended for new designs and ongoing procurement.

Q: Are there any compliance differences between these parts?

A: No. Both the EEF-SX0G820R and EEF-SX0G820ER are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards.

Q: Can I use the EEF-SX0G820ER in high-frequency applications?

A: The EEF-SX0G820ER is rated for 6.3 A ripple current at 100 kHz. Verify that this ripple current specification meets your application requirements before selection.
