107SAK010M Equivalent & Substitute Parts Reference

Part Overview

The 107SAK010M is a 100 µF, 10 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the SAK series. This radial, through-hole component is rated for 2000 hours at 85°C with an operating temperature range of -40°C to 85°C. The part is currently Active in product status and ROHS3 compliant.

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required):

UFW1A101MDD, UKW1A101MDD, and SK101M010ST are direct electrical and mechanical equivalents to the 107SAK010M. All three parts maintain identical capacitance, voltage rating, tolerance, lead spacing, diameter, and mounting configuration. UFW1A101MDD and UKW1A101MDD are Nichicon products with Obsolete status but equivalent performance specifications. SK101M010ST is a Cornell Dubilier product with Active status, offering supply continuity within the same manufacturer family.

Height variation exists among direct substitutes: UFW1A101MDD and EKZE100ELL101ME11D measure 0.492" (12.50 mm), UKW1A101MDD and UHE1A101MDD measure 0.433" (11.00 mm), and SK101M010ST measures 0.512" (13.00 mm) compared to the original 0.413" (10.50 mm). PCB clearance must be verified before selection.

For Enhanced Performance (Design Upgrade Path):

EEU-EB1A101S (Panasonic) provides the highest lifetime rating at 5000 hours at 105°C with extended operating temperature range to 105°C. This part is Active in product status and suitable for applications requiring enhanced reliability.

EKZE100ELL101ME11D (Chemi-Con) offers 2000 hours at 105°C with extended operating temperature range and Active product status. This part provides a balance between performance enhancement and availability.

UHE1A101MDD (Nichicon) delivers 4000 hours at 105°C with extended operating temperature range, though product status is Obsolete.

UPW1A101MDD (Nichicon) extends the operating temperature range to -55°C to 105°C with 2000 hours at 105°C lifetime, suitable for extreme temperature applications.

Compliance and Certification:

All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the 107SAK010M. All parts carry ECCN EAR99 and HTSUS 8532.22.0020 classifications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher height rating?

A: Yes, provided PCB layout clearance is verified. The 107SAK010M has a seated height of 0.413" (10.50 mm). Substitute parts range from 0.433" to 0.512" in height. Confirm that the increased height does not interfere with adjacent components, solder bridges, or enclosure constraints before implementation.

Q: What is the difference between Direct Substitutes and Upgrade Substitutes?

A: Direct Substitutes (UFW1A101MDD, UKW1A101MDD, SK101M010ST) maintain identical electrical specifications and lifetime ratings as the 107SAK010M. Upgrade Substitutes (EEU-EB1A101S, EKZE100ELL101ME11D, UHE1A101MDD, UPW1A101MDD) extend lifetime ratings or operating temperature ranges while maintaining all critical electrical parameters. Upgrade substitutes are suitable when design requirements demand enhanced reliability or operation in higher temperature environments.

Q: Are Obsolete product status parts acceptable for new designs?

A: Obsolete parts (UFW1A101MDD, UKW1A101MDD, UHE1A101MDD, UPW1A101MDD) are no longer manufactured by their respective suppliers. While electrical specifications remain valid, long-term supply availability is not guaranteed. For new designs, Active status parts (107SAK010M, EEU-EB1A101S, EKZE100ELL101ME11D, SK101M010ST) are recommended to ensure supply chain continuity.

Q: Can I substitute a 16 V rated capacitor for the 10 V 107SAK010M?

A: No. The 107SAK010M is specified for 10 V operation. Substitution with higher voltage ratings (such as UKW1C101MDD at 16 V) changes the electrical characteristics and is not a valid equivalent. Voltage rating must match exactly for direct substitution.

Q: What parameters must match exactly between the main part and substitute?

A: Capacitance (100 µF), voltage rating (10 V), tolerance (±20%), lead spacing (0.079" / 2.00 mm), diameter (0.197" / 5.00 mm), package type (Radial, Can), and mounting type (Through Hole) must match exactly. Operating temperature range, lifetime rating, and height may vary within the constraints of PCB design and application requirements.

Q: Which substitute offers the best long-term reliability?

A: EEU-EB1A101S (Panasonic EB-A series) offers the highest lifetime rating at 5000 hours at 105°C with Active product status. This part is suitable for applications requiring extended service life and is currently manufactured and available.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (UFW1A101MDD, UKW1A101MDD, EEU-EB1A101S, EKZE100ELL101ME11D, UHE1A101MDD, UPW1A101MDD, SK101M010ST) are ROHS3 compliant and REACH unaffected, matching the regulatory compliance of the 107SAK010M.

Q: What is the difference between ESR and Impedance specifications?

A: ESR (Equivalent Series Resistance) and Impedance are related but distinct parameters. The 107SAK010M specifies ESR at 3.979 Ohm @ 120 Hz. Substitute parts may list Impedance values (measured in milliohms at different frequencies) instead of ESR. Both parameters indicate the capacitor's resistance to AC current flow. Specific values depend on measurement frequency and are provided in individual datasheets.

Q: Can I use SK101M010ST as a direct replacement for 107SAK010M?

A: Yes. SK101M010ST is a Cornell Dubilier product with identical electrical specifications (100 µF, 10 V, ±20% tolerance) and mechanical dimensions (0.079" lead spacing, 0.197" diameter, radial through-hole package). SK101M010ST has Active product status, providing supply continuity. Height is 0.512" (13.00 mm) compared to 0.413" (10.50 mm) for the 107SAK010M; PCB clearance must be verified.
