Part Overview

The TPS92315DBVR is an AC DC offline switcher LED driver IC manufactured by Texas Instruments, designed for single-output flyback topology applications. This device operates across a 9V to 35V supply range with a fixed 130kHz switching frequency and is housed in a SOT-23-6 surface mount package. The part is currently active in production status with ROHS3 compliance and MSL 2 moisture sensitivity rating.

Substitute parts are identified when design requirements necessitate alternative packaging formats, different supply voltage ranges, alternative topologies, or when primary part availability is constrained. Equivalent parts maintain functional compatibility within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the TPS92315DBVR are classified based on the following substitution criteria:

Parametric Equivalent (Packaging Variant): TPS92315DBVT maintains identical electrical specifications and topology but differs in packaging format (Tape & Reel versus Cut Tape). This substitution applies when supply chain or procurement requirements necessitate alternative tape configurations while preserving the same die and performance characteristics.

Manufacturer Recommended Substitutes: AL9910A-5S-13, MP4030GS, and RT7306DGS are classified as functional alternatives when the primary part is unavailable. These substitutes share the following critical parameters:

• AC DC offline switcher classification
• Single output configuration
• Surface mount technology
• ROHS3 compliance
• REACH unaffected status
• EAR99 export classification

Substitution compatibility is determined by matching the following key parameters: supply voltage overlap, topology compatibility (flyback or multi-topology support), dimming capability, operating temperature range, and package footprint compatibility with PCB layout constraints.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance): TPS92315DBVT is the direct parametric equivalent to TPS92315DBVR. Both devices share identical electrical specifications, topology, and performance characteristics. Selection between these two parts is determined solely by packaging procurement requirements: Cut Tape (CT) & Digi-Reel for TPS92315DBVR or Tape & Reel (TR) for TPS92315DBVT.

Functional Substitutes (Supply Voltage Considerations): AL9910A-5S-13 operates across a wider supply voltage range (20V to 500V) compared to the TPS92315DBVR (9V to 35V). This substitute is suitable for applications requiring extended high-voltage capability but is not compatible with designs operating below 20V supply. The AL9910A-5S-13 employs Step-Down and Step-Up topology with PWM and Analog dimming support, operating at 300kHz frequency.

Functional Substitutes (Voltage Range Overlap): MP4030GS and RT7306DGS both operate within overlapping supply voltage ranges (11V to 27V and 11V to 34V respectively) relative to the TPS92315DBVR upper range. Both maintain flyback topology compatibility and support surface mount installation. MP4030GS provides Triac dimming capability, while RT7306DGS offers Analog dimming with multi-topology support (Flyback, Step-Down, Step-Up).

Compliance and Certification: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory equivalence with the primary part. Moisture sensitivity levels vary: TPS92315DBVT and MP4030GS maintain MSL 2 rating, while AL9910A-5S-13 provides superior MSL 1 rating, and RT7306DGS operates at MSL 3.

Temperature Range Considerations: TPS92315DBVR and TPS92315DBVT specify junction temperature range of -20°C to 125°C. AL9910A-5S-13 operates at -40°C to 85°C ambient temperature, providing lower maximum temperature capability. MP4030GS and RT7306DGS both support -40°C to 125°C junction temperature range, matching or exceeding the primary part specification.

Frequently Asked Questions (FAQ)

Q: Can TPS92315DBVT be used as a direct replacement for TPS92315DBVR?

A: Yes. TPS92315DBVT is a parametric equivalent with identical electrical specifications, topology, and performance. The only difference is packaging format: TPS92315DBVR is supplied in Cut Tape & Digi-Reel format, while TPS92315DBVT is supplied in Tape & Reel format. Selection depends on procurement and assembly requirements.

Q: What are the key differences between TPS92315DBVR and AL9910A-5S-13?

A: AL9910A-5S-13 operates across a significantly wider supply voltage range (20V to 500V) compared to TPS92315DBVR (9V to 35V). AL9910A-5S-13 employs Step-Down and Step-Up topology with PWM and Analog dimming, operates at 300kHz frequency, and is housed in an 8-SOIC package. TPS92315DBVR uses flyback topology in a SOT-23-6 package. AL9910A-5S-13 is not suitable for applications requiring supply voltages below 20V.

Q: Are MP4030GS and RT7306DGS compatible with TPS92315DBVR applications?

A: MP4030GS and RT7306DGS are functional alternatives when supply voltage requirements fall within their operating ranges (11V to 27V and 11V to 34V respectively). Both support flyback topology and surface mount installation. However, package footprints differ: MP4030GS and RT7306DGS use 8-SOIC packages, while TPS92315DBVR uses SOT-23-6. PCB layout modifications are required for package substitution.

Q: What is the significance of MSL (Moisture Sensitivity Level) ratings in part selection?

A: MSL ratings indicate moisture sensitivity during storage and handling. TPS92315DBVR and TPS92315DBVT carry MSL 2 (1 Year), requiring controlled storage conditions. AL9910A-5S-13 provides superior MSL 1 (Unlimited) rating, allowing indefinite storage without moisture control. RT7306DGS operates at MSL 3 (168 Hours), requiring more stringent moisture control than the primary part.

Q: Can AL9910A-5S-13 be used in applications designed for TPS92315DBVR operating at 9V to 15V supply?

A: No. AL9910A-5S-13 minimum supply voltage is 20V. This substitute is incompatible with applications requiring supply voltages below 20V. Use MP4030GS or RT7306DGS for applications operating within the 11V to 27V or 11V to 34V ranges respectively.

Q: What packaging considerations apply when substituting TPS92315DBVR with MP4030GS or RT7306DGS?

A: TPS92315DBVR uses SOT-23-6 package (6-pin), while MP4030GS and RT7306DGS use 8-SOIC packages (8-pin). These packages have different pin counts, footprints, and pinout configurations. Direct PCB substitution is not possible without schematic redesign and PCB layout modification. Pin function mapping must be verified against individual datasheets.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TPS92315DBVR, TPS92315DBVT, AL9910A-5S-13, MP4030GS, and RT7306DGS are all ROHS3 compliant and REACH unaffected, ensuring regulatory equivalence for environmental and hazardous substance restrictions.
