Substitute Part Grouping Explanation

Substitution for the 35MS710MEFC4X7 is determined by strict equivalence across electrical and mechanical parameters. All substitute parts maintain identical capacitance (10 µF), voltage rating (35 V), tolerance (±20%), and physical dimensions (0.157" diameter, 0.315" height, 0.059" lead spacing). All candidates are through-hole radial can packages with polar electrolytic construction.

The three qualified substitutes are:

35ML10MEFC4X7 (Rubycon ML series): Same manufacturer, upgraded lifetime specification (5000 Hrs @ 105°C vs. 1000 Hrs @ 85°C), extended operating temperature range to 105°C
106PUM035M (Cornell Dubilier / Illinois Capacitor PUM series): Active product status, 2000-hour lifetime at 85°C, specified ESR of 19.894 Ω @ 120 Hz
ESRG350ELL100MD07D (Chemi-Con SRG series): Active product status, 2000-hour lifetime at 85°C, higher ripple current capability at high frequency (57.6 mA @ 100 kHz)

Engineering Selection Recommendations

For new designs and long-term procurement: Select either 106PUM035M or ESRG350ELL100MD07D. Both are active products with current manufacturing status, ensuring supply chain continuity. The 106PUM035M provides specified ESR characteristics (19.894 Ω @ 120 Hz) for applications requiring known impedance profiles. The ESRG350ELL100MD07D offers superior high-frequency ripple current handling (57.6 mA @ 100 kHz), suitable for switching power supply applications.

For direct replacement in existing designs: The 35ML10MEFC4X7 provides the closest electrical upgrade path within the Rubycon product family, offering extended temperature range (-40°C to 105°C) and significantly improved lifetime (5000 Hrs @ 105°C). However, note that this part is also classified as obsolete.

Compliance considerations: All substitute parts maintain ROHS3 or RoHS compliance and REACH unaffected status, matching the original part's regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the 35ML10MEFC4X7 be used as a direct drop-in replacement for the 35MS710MEFC4X7?

A: Yes. Both parts share identical electrical specifications (10 µF, 35 V, ±20% tolerance) and physical dimensions (0.157" diameter, 0.315" height, 0.059" lead spacing). The ML series offers improved lifetime and extended operating temperature range, making it a superior upgrade within the same manufacturer's portfolio.

Q: What is the difference between the Cornell Dubilier 106PUM035M and Chemi-Con ESRG350ELL100MD07D?

A: Both parts meet the core electrical and mechanical requirements. The 106PUM035M specifies ESR at 19.894 Ω @ 120 Hz, enabling precise impedance calculations. The ESRG350ELL100MD07D provides higher ripple current capability at high frequency (57.6 mA @ 100 kHz versus unspecified for 106PUM035M), making it preferable for high-frequency switching applications.

Q: Are there any package or footprint differences between these substitutes?

A: No. All substitute parts are identical in physical dimensions and through-hole lead spacing (0.059" / 1.50 mm). PCB layout and mounting procedures remain unchanged.

Q: Why are some substitutes listed as obsolete?

A: The 35ML10MEFC4X7 is obsolete but remains available in inventory. For new designs requiring long-term supply assurance, prioritize active products: 106PUM035M or ESRG350ELL100MD07D.

Q: Do all substitutes meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 or RoHS compliant and REACH unaffected, matching the original part's regulatory requirements.
