Parameter Comparison

Engineering Selection Recommendations

108SAK025M (Cornell Dubilier / Illinois Capacitor, SAK Series)

This is the primary part specification. Selection is appropriate when original manufacturer continuity is required or when the specific ESR and ripple current characteristics are critical to circuit performance. Product status is Active with full RoHS3 and REACH compliance.

SK102M025ST (Cornell Dubilier Electronics, SK Series)

This substitute is qualified for applications where the lower ESR value (180 mOhm versus 265 mOhm) provides performance advantage. Physical dimensions differ: the SK102M025ST has a larger diameter (0.512" versus 0.492") and greater height (0.906" versus 0.650"), requiring PCB layout verification. Lead spacing remains identical at 0.197" (5.00mm). Product status is Active with full RoHS3 and REACH compliance. This part is suitable when space constraints permit the larger form factor and lower ESR is beneficial.

URS1E102MHD (Nichicon, URS Series)

This substitute is qualified as a parametric equivalent with identical physical dimensions to the 108SAK025M (0.492" diameter, 0.650" height). Ripple current ratings are comparable to the main part (830 mA @ 120 Hz and 954.5 mA @ 10 kHz). ESR is not specified for this part. Product status is Active with full RoHS3 and REACH compliance. This part is suitable for direct form-factor replacement when manufacturer diversification is acceptable.

All three parts are Active in product status and meet regulatory requirements for RoHS3 and REACH compliance, making them suitable for new designs and production applications.

Frequently Asked Questions (FAQ)

Q: Can SK102M025ST be used as a direct replacement for 108SAK025M on existing PCBs?

A: SK102M025ST has identical lead spacing (0.197" / 5.00mm) and electrical specifications, but physical dimensions differ. The SK102M025ST is larger: 0.512" diameter and 0.906" height compared to 0.492" diameter and 0.650" height for the 108SAK025M. PCB layout must be verified to confirm adequate clearance before substitution.

Q: What is the significance of ESR differences between these parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat generation. The 108SAK025M has 265 mOhm ESR, while SK102M025ST has 180 mOhm ESR. Lower ESR reduces heat dissipation and improves performance in high-ripple-current applications. The URS1E102MHD does not specify ESR. Selection depends on circuit ripple current requirements.

Q: Are all three parts suitable for new product designs?

A: Yes. All three parts are Active in product status and fully compliant with RoHS3 and REACH regulations, making them suitable for new designs. Selection should be based on availability, manufacturer preference, physical space constraints, and specific ESR or ripple current requirements.

Q: What is the difference between the 108SAK025M and URS1E102MHD in terms of physical footprint?

A: Both parts have identical physical dimensions: 0.492" diameter and 0.650" height. Lead spacing is identical at 0.197" (5.00mm). These parts are direct form-factor replacements on PCBs designed for either component.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: All three parts meet the 2000 Hrs @ 85°C lifetime specification. The 108SAK025M and URS1E102MHD have comparable ripple current ratings (943 mA and 954.5 mA @ 10 kHz respectively). SK102M025ST does not specify ripple current. For applications with specific ripple current requirements, the 108SAK025M or URS1E102MHD are preferred.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are RoHS3 Compliant and REACH Unaffected. All carry ECCN classification EAR99 and HTSUS code 8532.22.0020. Moisture Sensitivity Level is 1 (Unlimited) for 108SAK025M and SK102M025ST; URS1E102MHD is Not Applicable.
