Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AL1692-20CS7-13 are qualified based on the following critical parameters:

• Functional Type: AC/DC Offline Switcher with internal switch capability
• Topology Support: Flyback, Step-Down (Buck), and Step-Up (Boost) configurations
• Output Configuration: Single output
• Supply Voltage Range: Minimum 8.5V or lower; Maximum 20V or higher
• Current Capability: 2A or greater per output channel
• Switching Frequency: 4kHz or compatible frequency range
• Dimming Capability: Triac dimming support
• Package Compatibility: Surface mount with equivalent or compatible footprint dimensions
• Compliance: ROHS3 compliant, REACH unaffected status

The TPS92411PDDA from Texas Instruments qualifies as a substitute based on its AC/DC offline switcher topology, single-output configuration, internal switch integration, and surface mount packaging. Both parts support the required topologies and dimming applications for LED driver implementations.

Parameter Comparison

Engineering Selection Recommendations

Both the AL1692-20CS7-13 and TPS92411PDDA maintain active production status and comply with ROHS3 and REACH requirements. The TPS92411PDDA offers an extended maximum supply voltage range (94V versus 20V) and higher maximum operating junction temperature (150°C versus 105°C), providing broader application flexibility. The AL1692-20CS7-13 features unlimited moisture sensitivity level (MSL 1) compared to the TPS92411PDDA's one-year MSL rating (MSL 2). Package footprints are compatible at 0.154" width (3.90mm), though the TPS92411PDDA utilizes a PowerSOIC variant with integrated thermal pad. Selection between these parts should be based on specific supply voltage requirements, thermal environment constraints, and packaging requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can the TPS92411PDDA directly replace the AL1692-20CS7-13 in existing designs?

A: Both parts share compatible package dimensions (0.154" / 3.90mm width) and support identical topologies (Flyback, Step-Down, Step-Up). However, the TPS92411PDDA features a PowerSOIC package variant with thermal pad, which may require PCB layout modifications. Verify supply voltage requirements fall within both parts' ranges (AL1692: 8.5V-20V; TPS92411: 7.5V-94V).

Q: What are the key differences in electrical specifications?

A: The TPS92411PDDA supports a significantly wider maximum supply voltage (94V versus 20V) and operates at higher junction temperatures (150°C versus 105°C). The AL1692-20CS7-13 specifies 2A output current; the TPS92411PDDA does not specify this parameter in the provided data. Both support AC/DC offline switching with internal switches and single-output configurations.

Q: Are there moisture sensitivity considerations for long-term storage?

A: The AL1692-20CS7-13 carries MSL 1 (unlimited shelf life), while the TPS92411PDDA carries MSL 2 (one-year shelf life). For applications requiring extended storage periods without controlled humidity, the AL1692-20CS7-13 offers superior moisture tolerance.

Q: Do both parts support Triac dimming?

A: The AL1692-20CS7-13 explicitly specifies Triac dimming capability. The TPS92411PDDA dimming specification is not provided in the available data. Confirm dimming requirements with device datasheets before substitution.

Q: Are there packaging considerations for thermal management?

A: The TPS92411PDDA includes an integrated PowerPad thermal pad in its 8-PowerSOIC package, providing enhanced thermal dissipation compared to the standard 7-SO package of the AL1692-20CS7-13. Applications with higher thermal loads may benefit from the TPS92411PDDA's thermal pad design.
