EEF-SX0G101R Equivalent & Substitute Parts

Part Overview

The EEF-SX0G101R is a 100 µF, 4 V aluminum polymer surface mount capacitor manufactured by Panasonic Electronic Components in the SP-Cap SX series. This component is classified as Not For New Designs, indicating it has been superseded in Panasonic's product portfolio. The part operates across a temperature range of -55°C to 105°C with a 2000-hour lifetime rating at 105°C, making it suitable for general-purpose applications requiring stable capacitance in compact form factors.

Identifying equivalent and substitute parts is necessary due to the product's discontinued status for new designs. Equivalent alternatives maintain identical electrical and mechanical specifications while offering improved availability or active product status.

Substitute Part Grouping Explanation

Substitute parts for the EEF-SX0G101R are determined by strict equivalence across the following critical parameters:

Capacitance: 100 µF (exact match required)
Voltage Rating: 4 V (exact match required)
Tolerance: ±20% (exact match required)
Type: Aluminum Polymer (exact match required)
ESR: 9 mOhm (exact match required)
Lifetime: 2000 Hrs @ 105°C (exact match required)
Operating Temperature: -55°C to 105°C (exact match required)
Package: 2917 (7343 Metric) (exact match required)
Mounting: Surface Mount (exact match required)
Physical Dimensions: 0.287" L x 0.169" W, Height 0.079" max (exact match required)

Two substitute parts meet these criteria: EEF-SX0G101ER (Panasonic, Active status) and 875035019001 (Würth Elektronik, Active status). Both maintain full electrical and mechanical compatibility with the original part.

Engineering Selection Recommendations

For new designs, EEF-SX0G101ER is the primary recommended substitute. This part is manufactured by Panasonic, the original equipment manufacturer, maintains Active product status, and provides full parametric equivalence to the EEF-SX0G101R. The EEF-SX0G101ER offers superior long-term availability and supply chain stability compared to the discontinued original part.

The 875035019001 manufactured by Würth Elektronik is a secondary equivalent option. This part maintains identical electrical and mechanical specifications and holds Active product status. The Würth Elektronik alternative provides supply diversification and is suitable for applications where multi-source qualification is required. Both substitute parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0G101ER be used as a direct replacement for EEF-SX0G101R?

A: Yes. The EEF-SX0G101ER is a direct parametric equivalent. All electrical specifications (capacitance, voltage, tolerance, ESR, lifetime, operating temperature) and mechanical specifications (package, dimensions, mounting type) are identical. The primary difference is product status: EEF-SX0G101ER is Active, while EEF-SX0G101R is Not For New Designs.

Q: What is the difference between the Panasonic and Würth Elektronik substitutes?

A: Both EEF-SX0G101ER and 875035019001 are parametrically equivalent. The difference is manufacturer: Panasonic versus Würth Elektronik. Both parts meet identical electrical and mechanical requirements, RoHS3 compliance, and REACH status. Selection between them depends on supply availability, procurement preferences, and multi-source qualification requirements.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts use the 2917 (7343 Metric) package with identical dimensions: 0.287" L x 0.169" W (7.30 mm x 4.30 mm) and maximum seated height of 0.079" (2.00 mm). They are mechanically interchangeable on PCB layouts.

Q: What does "Not For New Designs" mean for the EEF-SX0G101R?

A: This designation indicates the part has been superseded in the manufacturer's product line. While existing inventory may be available, Panasonic does not recommend this part for new circuit designs. The EEF-SX0G101ER is the active replacement.

Q: Are there any compliance or certification differences?

A: No. All three parts are ROHS3 Compliant and REACH Unaffected. Regulatory compliance is identical across the main part and both substitutes.
