Key Parameters

Substitute Part Grouping Explanation

Substitution of the 16ML150MEFC8X7 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 150 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.138" (4.60 mm) (exact match required)
• Size / Dimension: 0.315" Dia (8.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)

Allowable Upgrade Parameters:

• Voltage - Rated: May be increased from 16 V to higher rated voltage (25 V or greater) while maintaining all other specifications
• Height - Seated (Max): May increase within mechanical envelope constraints
• Ripple Current: May increase with higher voltage rating
• Lifetime @ Temperature: Must maintain minimum 5000 Hrs @ 105°C

The substitute part 25ML150MEFC8X7.5 qualifies as an upgrade substitute due to increased voltage rating (25 V vs. 16 V) while maintaining identical capacitance, tolerance, polarization, lead spacing, diameter, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The 25ML150MEFC8X7.5 serves as a direct upgrade substitute for the 16ML150MEFC8X7. Both components maintain ROHS3 compliance and identical thermal lifetime specifications. The substitute part provides increased voltage rating (25 V vs. 16 V), which is compatible with circuits designed for 16 V operation. The marginal height increase (0.335" vs. 0.315") must be verified against available PCB clearance in the target application. Both parts are classified as obsolete; procurement should prioritize available inventory quantities.

Frequently Asked Questions (FAQ)

Q: Can the 25ML150MEFC8X7.5 replace the 16ML150MEFC8X7 in a 16 V circuit?

A: Yes. The substitute part is rated for 25 V, which exceeds the 16 V circuit requirement. Higher voltage rating does not degrade performance in lower voltage applications. All other electrical parameters (capacitance, tolerance, ripple current, temperature range) remain compatible.

Q: What is the physical difference between these two parts?

A: The primary physical difference is height: the main part measures 0.315" (8.00 mm) seated height, while the substitute measures 0.335" (8.50 mm). Diameter remains 0.315" (8.00 mm) for both. Lead spacing is identical at 0.138" (4.60 mm). Verify PCB clearance before substitution.

Q: Are both parts through-hole mounted?

A: Yes. Both the 16ML150MEFC8X7 and 25ML150MEFC8X7.5 are through-hole radial can capacitors with identical lead spacing, ensuring compatible PCB footprints.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and maintain identical thermal lifetime specifications of 5000 Hrs @ 105°C.

Q: Why is the ripple current higher on the substitute part?

A: The 25ML150MEFC8X7.5 exhibits higher ripple current capability (140 mA @ 120 Hz and 168 mA @ 10 kHz vs. 125 mA and 150 mA respectively) due to its higher voltage rating. This represents an improvement in performance margin.
