Primary Equivalence Parameters:

• Manufacturer: onsemi (same manufacturer ensures design continuity)
• Category: Power Management (PMIC)
• Type: AC DC Offline Switcher
• Topology: Flyback, SEPIC, Step-Down (Buck), Step-Up (Boost)
• Number of Outputs: 1
• Voltage - Supply (Min): 8.8V
• Voltage - Supply (Max): 25.5V
• Dimming: Analog, PWM
• Applications: Lighting
• Operating Temperature: -40°C ~ 125°C (TJ)
• Package / Case: 10-SOP (0.154", 3.90mm Width)
• Supplier Device Package: 10-SOIC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and are suitable for direct substitution in designs currently using the NCL30186ADR2G.

Parameter Comparison

Engineering Selection Recommendations

NCL30186BDR2G is the primary substitute for NCL30186ADR2G. Both parts share identical electrical and mechanical specifications. The NCL30186BDR2G maintains active product status with onsemi, ensuring long-term availability and technical support. The only difference is packaging format: NCL30186BDR2G is supplied in Tape & Reel (TR) format, which is standard for production environments. This part is suitable for direct replacement in all applications currently using the obsolete NCL30186ADR2G.

NCL30186DDR2G is an alternative parametric equivalent also manufactured by onsemi with active product status. This part meets all electrical and mechanical requirements identical to the main part and NCL30186BDR2G. NCL30186DDR2G is also supplied in Tape & Reel (TR) format. Selection between NCL30186BDR2G and NCL30186DDR2G should be based on inventory availability and procurement lead times, as both are functionally equivalent.

Both substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can NCL30186BDR2G or NCL30186DDR2G be used as direct replacements for NCL30186ADR2G?

A: Yes. Both parts are parametric equivalents meeting all electrical and mechanical specifications of the obsolete NCL30186ADR2G. They support identical topologies, voltage ranges, dimming methods, and operating temperatures. No circuit modifications are required for substitution.

Q: What is the difference between NCL30186BDR2G and NCL30186DDR2G?

A: Both parts are electrically and mechanically identical. The primary difference is product availability and inventory levels. NCL30186BDR2G has higher inventory (37,800 pcs), while NCL30186DDR2G has lower inventory (7,162 pcs). Selection should be based on procurement requirements and lead time considerations.

Q: Why is packaging format different between the main part and substitutes?

A: The NCL30186ADR2G is supplied in bulk packaging, while NCL30186BDR2G and NCL30186DDR2G are supplied in Tape & Reel (TR) format. Tape & Reel is the standard packaging for production assembly and automated placement equipment. Both formats contain the same component with identical electrical performance.

Q: Are there any temperature or compliance differences between these parts?

A: No. All three parts operate across the same temperature range (-40°C ~ 125°C TJ) and maintain identical RoHS3 compliance and MSL ratings. They are fully interchangeable from environmental and regulatory perspectives.

Q: What topologies does the NCL30186 series support?

A: The NCL30186 series supports Flyback, SEPIC, Step-Down (Buck), and Step-Up (Boost) topologies, enabling flexible design implementation for various LED driver applications.
