SPSX101M04R Equivalent & Substitute Parts Reference

Part Overview

The SPSX101M04R is a 100 µF, 4 V aluminum polymer surface mount capacitor manufactured by Cornell Dubilier Electronics (CDE) in the 2917 (7343 Metric) package. This component is classified as Obsolete, indicating it is no longer in active production. The part features a 9 mOhm equivalent series resistance (ESR) and supports a 1000-hour lifetime rating at 105°C with a maximum ripple current of 3 A at 100 kHz.

Due to its obsolete status, direct procurement from the original manufacturer is limited. Equivalent substitute parts from active manufacturers are available to maintain design continuity and ensure supply chain reliability for applications requiring this capacitance, voltage, and package specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPSX101M04R are qualified based on the following criteria:

Electrical Parameters (Critical):

• Capacitance: 100 µF (exact match required)
• Voltage Rating: 4 V (exact match required)
• Type: Aluminum Polymer (exact match required)
• Tolerance: ±20% (exact match required)
• ESR: 9 mOhm (exact match required)

Mechanical Parameters (Critical):

• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) (exact match required)

Environmental & Compliance Parameters (Important):

• Operating Temperature Range: Must support -40°C to 105°C minimum
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• REACH Status: REACH Unaffected (regulatory requirement)

Performance Enhancement (Beneficial but not required):

• Lifetime @ Temperature: Substitute parts with extended lifetime ratings (2000 Hrs @ 105°C vs. 1000 Hrs @ 105°C) provide improved reliability
• Ripple Current Capability: Higher ripple current ratings indicate enhanced performance margin

All substitute parts listed meet or exceed the critical electrical, mechanical, and compliance parameters of the original SPSX101M04R.

Engineering Selection Recommendations

Primary Recommendation: EEF-SX0G101ER

The EEF-SX0G101ER from Panasonic Electronic Components is the preferred substitute for the obsolete SPSX101M04R. This part meets all critical electrical and mechanical parameters while offering the following advantages:

• Active Product Status: Currently in active production, ensuring long-term supply chain availability
• Enhanced Reliability: 2000-hour lifetime rating at 105°C (double the original specification)
• Improved Performance: 6.3 A ripple current capability at 100 kHz (2.1× the original specification)
• Extended Temperature Range: -55°C to 105°C operating range provides broader environmental compatibility
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected
• Inventory Availability: 7147 pieces in stock

Secondary Option: EEF-SX0G101R

The EEF-SX0G101R is an alternative Panasonic substitute that meets all critical specifications. However, this part carries a "Not For New Designs" status, indicating it is in the later stages of its product lifecycle. This part is suitable for replacement applications only and should not be selected for new design implementations.

Compatibility Notes:

Both Panasonic substitutes feature a maximum seated height of 0.079" (2.00mm), which is 0.004" (0.10mm) lower than the original SPSX101M04R at 0.083" (2.10mm). This dimensional difference is within typical PCB design tolerances and does not affect functional compatibility. Verify clearance in your specific PCB layout if height-constrained applications are present.

Frequently Asked Questions (FAQ)

Q1: Can I use EEF-SX0G101ER as a direct replacement for SPSX101M04R?

Yes. The EEF-SX0G101ER meets all critical electrical parameters (100 µF, 4 V, 9 mOhm ESR, ±20% tolerance), mechanical specifications (2917 package, surface mount), and regulatory requirements (ROHS3, REACH Unaffected). The parts are electrically and mechanically interchangeable.

Q2: What is the difference between EEF-SX0G101ER and EEF-SX0G101R?

Both parts are electrically and mechanically identical in terms of capacitance, voltage, ESR, and package. The primary difference is product status: EEF-SX0G101ER is Active (recommended for new designs and replacements), while EEF-SX0G101R is Not For New Designs (suitable for replacement applications only). For new designs, select EEF-SX0G101ER.

Q3: Does the height difference between the original and substitute parts affect PCB compatibility?

The substitute parts are 0.004" (0.10mm) shorter in seated height (2.00mm vs. 2.10mm). This difference is negligible for most applications and falls within standard PCB design tolerances. Verify clearance in your specific layout if the application has height constraints or proximity to other components.

Q4: Are the substitute parts available in the same packaging as the original?

The substitute parts are supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly. The original SPSX101M04R packaging specification was not provided. Confirm your assembly process requirements with your manufacturing partner.

Q5: What are the key parameters that must match for substitution?

The following parameters must match exactly for electrical and mechanical compatibility:

• Capacitance: 100 µF
• Voltage Rating: 4 V
• Package / Case: 2917 (7343 Metric)
• Type: Aluminum Polymer
• Tolerance: ±20%
• ESR: 9 mOhm
• Mounting Type: Surface Mount

Q6: Can I use a substitute part with a higher voltage rating?

The provided substitute parts are specified at 4 V, matching the original. Using a higher voltage-rated part is not addressed in this reference and requires separate engineering evaluation.

Q7: What is the advantage of the extended lifetime rating on the substitute parts?

The substitute parts offer 2000-hour lifetime at 105°C compared to 1000 hours for the original. This provides improved reliability margin and extended operational life in high-temperature applications, reducing the risk of capacitor degradation over extended service periods.

Q8: Are both substitute parts ROHS3 compliant?

Yes. Both EEF-SX0G101ER and EEF-SX0G101R are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components in most markets.
