Engineering Selection Recommendations

For Direct Replacement (Same Thermal Profile): The 106RSS035M and 106RSS035MSA from Cornell Dubilier / Illinois Capacitor are parametric equivalents with active product status. Both maintain the original operating temperature range (-40°C ~ 85°C) and lifetime specification (1000 Hrs @ 85°C), ensuring compatibility in applications designed for the 35MS710MEFC5X7. These parts are ROHS3 compliant and REACH unaffected.

For Enhanced Thermal Performance: The Rubycon 35MH710MEFC5X7, 35ZLG10MEFC5X7, and Chemi-Con EKMA350ELL100ME07D provide extended operating temperature ranges (-40°C ~ 105°C) and improved lifetime ratings at elevated temperatures. These upgrades are suitable for applications requiring enhanced reliability or operation in higher temperature environments while maintaining identical mechanical and electrical specifications.

For Voltage Margin Enhancement: The Rubycon 50ML10MEFC5X7 provides a 50 V rating with extended lifetime (5000 Hrs @ 105°C). This part is suitable for applications where voltage margin or long-term reliability is prioritized, though it maintains identical physical dimensions and lead spacing.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use 50ML10MEFC5X7 as a direct replacement for 35MS710MEFC5X7? A: Yes. The 50ML10MEFC5X7 maintains identical capacitance (10 µF), tolerance (±20%), physical dimensions, lead spacing, and mounting type. The higher voltage rating (50 V vs. 35 V) is compatible with circuits designed for 35 V operation. The extended lifetime (5000 Hrs @ 105°C) provides additional reliability margin.

Q: What is the difference between 35ZLG10MEFC5X7 and 35MH710MEFC5X7? A: Both parts share identical electrical specifications (10 µF, 35 V, ±20%) and physical dimensions. The 35ZLG10MEFC5X7 provides higher ripple current capability (63 mA @ 120 Hz and 350 mA @ 100 kHz) and lower impedance (330 mOhms) compared to the 35MH710MEFC5X7. Selection depends on ripple current requirements in the application.

Q: Are Cornell Dubilier parts (106RSS035M, 106RSS035MSA) suitable for high-temperature applications? A: The Cornell Dubilier parts maintain the original operating temperature range (-40°C ~ 85°C) and lifetime specification (1000 Hrs @ 85°C). For applications requiring operation above 85°C, the Rubycon MH7, ZLG, or ML series, or the Chemi-Con KMA series are recommended.

Q: What is the difference between 106RSS035M and 106RSS035MSA? A: Both parts are parametric equivalents with identical capacitance, voltage, tolerance, and operating temperature range. The 106RSS035MSA provides additional ripple current capability at high frequency (630 mA @ 100 kHz), making it suitable for applications with higher AC ripple current demands.

Q: Do all substitute parts have the same physical footprint? A: Yes. All substitute parts maintain identical lead spacing (0.079" / 2.00 mm), diameter (0.197" / 5.00 mm), and maximum height (0.315" / 8.00 mm), ensuring direct PCB compatibility without layout modifications.

Q: Are these parts suitable for new designs or only legacy replacement? A: The Cornell Dubilier 106RSS035M and 106RSS035MSA carry active product status and are suitable for new designs. All other parts listed are obsolete and recommended for legacy system maintenance and replacement applications only.
