Substitute Part Grouping Explanation

Substitute parts for the AP1694AS-13 are selected based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• AC/DC Offline Switcher topology with single output
• Triac dimming support for lighting applications
• Surface mount packaging in 8-SOIC or compatible form factor
• Operating temperature range of -40°C to 105°C or higher
• Supply voltage range overlap with 7V–25V specification
• RoHS3 compliance and REACH unaffected status

Substitution Categories:

Category 1: Direct Topology Match (Flyback, Buck, Boost) Parts AL1692S-13, UCC28811DR, and MP4032-2GS-Z maintain identical topology support (Flyback, Step-Down, Step-Up) with Triac dimming in 8-SOIC packaging. These provide the closest functional equivalence.

Category 2: Simplified Topology (Flyback or Buck Only) Parts TPS92001DGKR and NCL30060BDR2G support Flyback and Buck topologies with Triac dimming (or dimming capability) in compatible surface mount packages. These are suitable for applications not requiring Boost functionality.

Category 3: Alternative Topology with Internal Switch Parts LNK404LG and LYT1604D-TL feature integrated internal switches and different package types (eSIP-7F and 8-SOIC respectively). These support Flyback or Buck topologies with Triac dimming for specialized lighting applications.

Category 4: Compact Form Factor Alternative Part MP4088GJ-P operates at lower supply voltages (4.5V–5V) in a smaller TSOT-23-5 package with Buck/Boost topology and Triac dimming, suitable for low-voltage lighting driver designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: AL1692S-13 AL1692S-13 is the manufacturer-recommended direct substitute from Diodes Incorporated. It maintains identical topology support (Flyback, Buck, Boost), Triac dimming, 8-SOIC packaging, and operating temperature range. Supply voltage range (8.5V–20V) overlaps the AP1694AS-13 specification. Product status is Active with ROHS3 compliance and REACH unaffected certification. This part is the preferred choice for direct replacement in existing designs.

Secondary Recommendation: UCC28811DR UCC28811DR from Texas Instruments provides equivalent topology (Flyback, Buck, Boost) and Triac dimming in 8-SOIC packaging. Maximum supply voltage of 18V is within the AP1694AS-13 range. Product status is Active with full compliance certifications. This part is suitable for designs requiring Texas Instruments sourcing or supply chain diversification.

Alternative for Extended Temperature: MP4032-2GS-Z MP4032-2GS-Z from Monolithic Power Systems supports Buck and Boost topologies with Triac dimming in 8-SOIC packaging. Operating temperature extends to 125°C (versus 105°C for AP1694AS-13), providing thermal margin for demanding applications. Supply voltage range (10.3V–27V) exceeds the original specification. Product status is Active with ROHS3 compliance.

Specialized Applications:

For applications requiring Flyback topology only with high-voltage input capability, LNK404LG (Power Integrations, eSIP-7F package, 36V–725V input) is suitable for AC mains-powered lighting drivers with extended temperature range (-40°C to 150°C).

For low-voltage lighting driver designs (4.5V–5V), MP4088GJ-P in TSOT-23-5 package provides Buck/Boost topology with Triac dimming and compact form factor.

Avoid: TPS92001DGKR is classified as Last Time Buy and should not be selected for new designs requiring long-term supply availability.

Frequently Asked Questions (FAQ)

Q: Can AL1692S-13 be used as a direct drop-in replacement for AP1694AS-13? A: AL1692S-13 is functionally equivalent in topology, dimming capability, and package type. Supply voltage range (8.5V–20V) overlaps the AP1694AS-13 specification (7V–25V). Verify that your application operates within the 8.5V minimum threshold. Pin configuration and control signal compatibility must be confirmed against device datasheets.

Q: What is the key difference between AL1692S-13 and UCC28811DR? A: Both parts support identical topologies (Flyback, Buck, Boost) and Triac dimming in 8-SOIC packaging. AL1692S-13 is from Diodes Incorporated with supply range 8.5V–20V. UCC28811DR is from Texas Instruments with maximum supply of 18V. Selection depends on manufacturer preference and supply chain strategy.

Q: Why does MP4032-2GS-Z have a higher maximum operating temperature? A: MP4032-2GS-Z is rated to 125°C (junction temperature) compared to 105°C for AP1694AS-13. This reflects different thermal design and manufacturing process. The extended temperature rating provides additional margin for high-ambient or high-power applications but does not indicate superior performance in standard operating conditions.

Q: Is NCL30060BDR2G a suitable substitute if Triac dimming is not required? A: NCL30060BDR2G supports Flyback and Buck topologies in 7-SOIC packaging with supply range 8.8V–28V. It does not specify Triac dimming capability. This part is suitable only for applications that do not require dimming functionality.

Q: Can MP4088GJ-P replace AP1694AS-13 in existing designs? A: MP4088GJ-P operates at significantly lower supply voltages (4.5V–5V) and uses a smaller TSOT-23-5 package. It is not a direct replacement for the AP1694AS-13 (7V–25V, 8-SOIC). This part is suitable only for new low-voltage lighting driver designs.

Q: What compliance certifications apply to all substitute parts? A: All recommended substitute parts are ROHS3 compliant and REACH unaffected. Verify specific certifications (UL, FCC, CE) required for your application against individual device datasheets and regional requirements.

Q: Should I consider LNK404LG for standard lighting applications? A: LNK404LG is designed for high-voltage AC mains input (36V–725V) with integrated internal switch and eSIP-7F through-hole package. It is not suitable for standard 7V–25V DC supply applications. This part is intended for specialized AC mains-powered lighting driver designs only.
