Key Parameters

Substitute Part Grouping Explanation

Substitution for the 107SML050MD10 is determined by the following core electrical and mechanical parameters:

• Electrical equivalence: Capacitance value (100 µF), voltage rating (50 V), tolerance (±20%)
• Physical compatibility: Surface mount package type (Radial, Can - SMD), body diameter (10.00mm), similar seated height
• Environmental compliance: ROHS3 compliance, MSL 1 rating, operating temperature range capability
• Polarization: Polar orientation (electrolytic aluminum capacitor)

All listed substitute parts match these critical parameters, enabling direct functional replacement within the specified constraints.

Parameter Comparison

Engineering Selection Recommendations

ATB107M050 (Cornell Dubilier / Illinois Capacitor): This substitute offers improved performance characteristics within the same manufacturer family. The lower ESR (1.59 Ohm vs. 1.99 Ohm) and enhanced thermal lifetime (5000 Hrs @ 105°C vs. 2000 Hrs @ 85°C) make this suitable for applications requiring higher reliability. Expanded operating temperature range (-55°C to 105°C) and significantly higher ripple current ratings (469 mA @ 120 Hz, 670 mA @ 100 kHz) provide design margin for demanding circuits. ROHS3 compliance and MSL 1 rating ensure full environmental regulatory compatibility.

RVJ-50V101MH10U-R (Elna America): This alternative offers comparable electrical performance with a 100 µF, 50 V specification. Extended operating temperature range (-55°C to 105°C) and 2000 Hrs @ 105°C lifetime rating support thermal robustness. Ripple current specifications (324 mA @ 120 Hz, 486 mA @ 100 kHz) fall between the original and upgraded options. Full ROHS3 compliance and MSL 1 rating confirm regulatory alignment. Supplied in Tape & Reel packaging for automated assembly processes.

All substitutes maintain identical electrical classification, mechanical footprint compatibility within tolerance, and compliance certifications as the original 107SML050MD10.

Frequently Asked Questions (FAQ)

Q: What are the primary substitution criteria for the 107SML050MD10?

A: Direct substitutes must meet the following requirements: 100 µF capacitance, 50 V voltage rating, ±20% tolerance, radial can-type surface mount package with 10.00mm diameter, polar aluminum electrolytic construction, ROHS3 compliance, and MSL 1 rating. Physical height and land size variations within 0.05" (1.27mm) tolerance are acceptable for PCB layout flexibility.

Q: Are there physical mounting differences between substitute parts?

A: The ATB107M050 and RVJ-50V101MH10U-R have slightly larger surface mount land sizes (10.80mm x 10.50mm and 10.40mm x 10.40mm, respectively) compared to the original 107SML050MD10 (10.00mm x 10.00mm). Seated height is marginally reduced (0.413" vs. 0.417"), which is beneficial for space-constrained designs. PCB footprint patterns should be verified for clearance compatibility.

Q: What performance advantages do substitute parts offer?

A: The ATB107M050 provides the most significant performance upgrade with substantially higher ripple current capacity (469 mA @ 120 Hz vs. 250 mA) and extended thermal lifetime (5000 Hrs @ 105°C). The RVJ-50V101MH10U-R offers moderate ripple current improvement (324 mA @ 120 Hz) with comparable thermal ratings to the original part at elevated temperatures.

Q: Is cross-manufacturer substitution (Cornell Dubilier to Elna) acceptable?

A: Yes. The RVJ-50V101MH10U-R from Elna America is equivalent in electrical and physical specifications. Both manufacturers provide ROHS3-compliant, MSL 1-rated components suitable for industrial and consumer applications. Procurement, delivery, and warranty terms may vary between manufacturers.

Q: Can the 107SML050MD10 be replaced in existing designs without design changes?

A: The ATB107M050 and RVJ-50V101MH10U-R are direct replacements with no circuit redesign required. Verify PCB footprint clearances due to minor land size variations. Improved ripple current and thermal performance of substitutes do not introduce compatibility issues and are additive benefits in power delivery and thermal management circuits.
