Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP1695-20CS7-13 are categorized based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Type: AC DC Offline Switcher
• Topology: Flyback, Step-Down (Buck), Step-Up (Boost)
• Number of Outputs: 1
• Dimming: Triac
• Applications: Lighting
• Operating Temperature Range: -40°C ~ 105°C (TA)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Parameters:

• Internal Switch(s): Yes (preferred for direct replacement)
• Current - Output / Channel: 2A (preferred for direct replacement)
• Voltage - Supply Range: 7V to 25V (preferred for direct replacement)
• Package / Case: 8-SOIC, 7 Leads (preferred for direct replacement)

Substitute parts are grouped into two categories:

Category 1: Manufacturer Recommended Substitutes — Parts that maintain the same manufacturer (Diodes Incorporated) with active product status and full parameter compatibility within the specified ranges.

Category 2: Parametric Equivalents from Alternative Manufacturers — Parts from different manufacturers (Texas Instruments, Microchip Technology) that meet the core functional requirements but may have variations in supply voltage ranges, frequency specifications, or package configurations.

Parameter Comparison

Engineering Selection Recommendations

AL1692K-20CS7-13 — This Diodes Incorporated part is the closest parametric equivalent to the AP1695-20CS7-13. It maintains identical internal switch capability, 2A output current, Triac dimming, and 7-SO package configuration. The supply voltage range (8.5V to 18V) is narrower than the original but covers typical lighting application requirements. Product status is Active, ensuring long-term availability and supply chain stability. ROHS3 compliance and MSL 1 rating match the original specification.

AL1692S-13 — This Diodes Incorporated part provides an alternative with the same topology and Triac dimming support. The supply voltage range (8.5V to 20V) is slightly broader than AL1692K-20CS7-13. However, internal switch capability and output current specifications are not provided. Package is 8-SOIC standard configuration. Product status is Active with full compliance certifications.

TPS92411DBVR — This Texas Instruments part offers an alternative with internal switch capability and Flyback/Buck/Boost topology support. The supply voltage range extends to 100V, providing flexibility for higher voltage applications. Operating temperature range extends to 150°C (TJ), supporting higher thermal environments. Package is SOT-23-5, which differs from the original 7-SO configuration and requires PCB layout modification. Product status is Active.

UCC28811D — This Texas Instruments part supports Triac dimming and the required topology. The supply voltage maximum is specified at 18V. Internal switch capability is not provided. Package is 8-SOIC standard configuration. Product status is Active. Packaging is Tube rather than Tape & Reel.

HV9931LG-G — This Microchip Technology part supports AC/DC offline switching with extended supply voltage range (8V to 450V), suitable for universal input applications. Dimming is PWM-based rather than Triac, which represents a functional difference. Internal switch capability is not provided. Operating temperature range is limited to -40°C to 85°C (TA). Product status is Active.

Frequently Asked Questions (FAQ)

Q: Can AL1692K-20CS7-13 be used as a direct replacement for AP1695-20CS7-13?

A: AL1692K-20CS7-13 is the closest parametric equivalent. It maintains identical internal switch capability, 2A output current, Triac dimming, and 7-SO package. The supply voltage range (8.5V to 18V) is narrower than the original (7V to 25V), so verify that your application operates within this range. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between Triac dimming and PWM dimming?

A: Triac dimming is used for AC line-voltage dimming control in lighting applications, where the dimmer modulates the AC waveform. PWM (Pulse Width Modulation) dimming controls brightness by varying the duty cycle of a DC signal. These are fundamentally different dimming methods and are not interchangeable without circuit redesign.

Q: Why does HV9931LG-G have a different operating temperature range?

A: HV9931LG-G is specified with a maximum operating temperature of 85°C (TA), compared to 105°C for the original part. This reflects the thermal characteristics of the Microchip device and may limit its use in high-temperature environments. Verify that your application's ambient temperature requirements are compatible.

Q: Can I use TPS92411DBVR as a replacement if the package is different?

A: TPS92411DBVR uses SOT-23-5 package instead of the original 7-SO package. While the electrical function is compatible, the different package requires PCB layout modification, including new footprint design and trace routing. This is not a drop-in replacement without board redesign.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original AP1695-20CS7-13 specification.

Q: What should I consider when selecting between multiple substitutes?

A: Prioritize based on: (1) Product Status — Active parts ensure long-term availability; (2) Supply Voltage Range — Verify your application operates within the specified range; (3) Package Compatibility — Identical packages (7-SO or 8-SOIC) allow drop-in replacement; (4) Internal Switch Capability — Required if your design relies on integrated switching; (5) Dimming Method — Triac dimming is required for AC line-voltage dimming applications; (6) Operating Temperature — Confirm the part's temperature range matches your thermal requirements.
