Substitute Part Grouping Explanation

Substitute parts for the EEF-LL0G101R must maintain electrical and mechanical compatibility based on the following criteria:

• Capacitance Value: Must be 100 µF (exact match required)
• Voltage Rating: Must be 4 V or higher (equal or greater)
• Tolerance: Must be ±20% or tighter
• Package / Case: Must be 2917 (7343 Metric) for PCB compatibility
• Mounting Type: Must be Surface Mount
• Type: Must be Aluminum - Polymer
• Operating Temperature Range: Must encompass or exceed -40°C ~ 105°C
• Physical Dimensions: Must match or be compatible with the 0.287" L x 0.169" W footprint

The identified substitutes (EEF-SX0G101R and EEF-SX0G101ER) meet all mandatory electrical and mechanical parameters while offering improved performance in ESR and lifetime ratings.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: EEF-SX0G101ER is the recommended substitute. This part carries Active product status, ROHS3 compliance, and REACH unaffected designation, making it suitable for current and future production. The improved ESR (9 mOhm vs. 18 mOhm) and extended lifetime (2000 Hrs vs. 1000 Hrs @ 105°C) provide superior performance margins.

For Legacy System Maintenance: EEF-SX0G101R provides functional equivalence with identical electrical specifications to EEF-SX0G101ER. However, this part is designated Not For New Designs. Use only when EEF-SX0G101ER is unavailable and legacy system compatibility is required.

Compliance Considerations: Both substitute parts meet ROHS3 and REACH requirements, ensuring regulatory compliance for applications subject to these standards.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0G101R and EEF-SX0G101ER be used interchangeably?

A: Yes. Both parts share identical electrical specifications (100 µF, 4 V, ±20%, 9 mOhm ESR, 2000 Hrs @ 105°C) and the same 2917 (7343 Metric) package. The primary difference is product status: EEF-SX0G101ER is Active, while EEF-SX0G101R is Not For New Designs.

Q: What is the physical compatibility between the main part and substitutes?

A: All three parts use the 2917 (7343 Metric) package with identical footprints (0.287" L x 0.169" W). Height differences are minimal (1.90 mm main part vs. 2.00 mm substitutes), presenting no PCB layout conflicts for standard surface mount applications.

Q: Are there performance improvements with the substitute parts?

A: Yes. The EEF-SX series substitutes offer 50% lower ESR (9 mOhm vs. 18 mOhm) and doubled operational lifetime (2000 Hrs vs. 1000 Hrs @ 105°C). The operating temperature range is also extended to -55°C ~ 105°C, providing broader environmental tolerance.

Q: Which substitute should be selected for production applications?

A: EEF-SX0G101ER is the appropriate choice for production. Its Active status and full compliance certifications (ROHS3, REACH) ensure long-term availability and regulatory alignment.

Q: Are the substitutes available in the same packaging format?

A: Both substitutes are supplied in Tape & Reel (TR) packaging, standard for high-volume surface mount assembly. The main part EEF-LL0G101R does not specify packaging format in available data.
