EEF-SL0D101R Equivalent & Substitute Parts

Part Overview

The EEF-SL0D101R is a 100 µF, 2 V aluminum polymer capacitor in 2917 (7343 Metric) surface mount package manufactured by Panasonic Electronic Components. This part is classified as obsolete, making substitute components necessary for ongoing production and maintenance applications. The SP-Cap SL series has been superseded by newer polymer capacitor lines with improved performance characteristics and extended operational lifetimes.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the EEF-SL0D101R is determined by the following critical parameters:

Primary Compatibility Criteria:

• Capacitance value: 100 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical footprint: 0.287" L x 0.169" W (7.30mm x 4.30mm) (exact match required)

Secondary Compatibility Criteria (Allowable Variations):

• Voltage Rating: Rated voltage must be equal to or greater than 2 V
• ESR: Lower or equal ESR values are acceptable
• Lifetime @ Temperature: Extended lifetime is acceptable
• Operating Temperature Range: Extended range is acceptable
• Product Status: Active or Not For New Designs status preferred over obsolete

The substitute parts identified are grouped as follows:

Upgrade Category: EEF-SX0G101ER and EEF-SX0G101R provide higher voltage ratings (4 V) with identical capacitance, tolerance, and package specifications. These parts offer extended operational lifetime (2000 Hrs @ 105°C) and improved temperature range (-55°C ~ 105°C).

Similar Category: ECASD40D107M016K00 from Murata Electronics maintains the same 2 V voltage rating and 100 µF capacitance with identical package and footprint. This part is from a different manufacturer but meets the same electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: EEF-SX0G101ER is the preferred substitute. This part carries Active product status, ROHS3 compliance, and REACH unaffected certification. The 4 V voltage rating provides design margin above the original 2 V specification. Extended lifetime (2000 Hrs @ 105°C) and expanded operating temperature range (-55°C ~ 105°C) enhance system reliability. Identical ESR (9 mOhm) ensures equivalent electrical performance. Height increase from 0.071" to 0.079" must be verified against PCB layout constraints.

For Existing Designs (Maintenance/Repair): EEF-SX0G101R is available as an alternative upgrade option with identical electrical specifications to EEF-SX0G101ER. Product status is Not For New Designs, but the part remains in stock. ROHS3 compliance and REACH unaffected status are confirmed.

For Voltage-Matched Substitution: ECASD40D107M016K00 from Murata Electronics maintains the original 2 V voltage rating and identical package footprint. This part is suitable for applications where voltage margin is not required. ESR is higher at 16 mOhm compared to the original 9 mOhm specification. Product status is Obsolete, limiting long-term availability.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0G101ER be used as a direct replacement for EEF-SL0D101R?

A: Yes. Both parts share identical capacitance (100 µF), tolerance (±20%), package (2917 / 7343 Metric), and footprint (0.287" L x 0.169" W). The EEF-SX0G101ER provides higher voltage rating (4 V vs. 2 V), lower ESR (9 mOhm), and extended lifetime (2000 Hrs @ 105°C vs. 1000 Hrs @ 105°C). The seated height increases from 0.071" to 0.079", which must be confirmed against PCB clearance requirements.

Q: What is the difference between EEF-SX0G101ER and EEF-SX0G101R?

A: Both parts have identical electrical specifications: 100 µF, 4 V, 9 mOhm ESR, 2000 Hrs @ 105°C lifetime, and 2917 package. The primary difference is product status: EEF-SX0G101ER is Active, while EEF-SX0G101R is Not For New Designs. For new production, EEF-SX0G101ER is recommended.

Q: Why is the Murata part ECASD40D107M016K00 listed as a similar substitute rather than an upgrade?

A: ECASD40D107M016K00 maintains the original 2 V voltage rating and identical package footprint, making it voltage-matched to the EEF-SL0D101R. However, ESR is higher at 16 mOhm compared to 9 mOhm in the original part. The product status is Obsolete, similar to the main part. This part is suitable only when voltage margin is not required and ESR increase is acceptable.

Q: Are there height clearance concerns when substituting with upgrade parts?

A: Yes. The EEF-SX0G101ER and EEF-SX0G101R have a maximum seated height of 0.079" (2.00mm) compared to 0.071" (1.80mm) for the EEF-SL0D101R. This 0.008" (0.20mm) increase must be verified against PCB layout, component stacking, and enclosure clearance specifications.

Q: Are all substitute parts RoHS and REACH compliant?

A: EEF-SX0G101ER and EEF-SX0G101R are both ROHS3 Compliant and REACH Unaffected. ECASD40D107M016K00 is ROHS3 Compliant and REACH Unaffected. The original EEF-SL0D101R compliance status is not specified in the provided data.

Q: What is the Moisture Sensitivity Level (MSL) for substitute parts?

A: MSL information is provided only for the main part (EEF-SL0D101R: MSL 3, 168 Hours) and the Murata part (ECASD40D107M016K00: MSL 3, 168 Hours). MSL data for the Panasonic upgrade parts (EEF-SX0G101ER and EEF-SX0G101R) is not specified in the provided data.
