AP1682MTR-OG1 LED Driver IC Equivalent & Substitute Parts

Part Overview

The AP1682MTR-OG1 is an AC DC offline switcher LED driver IC manufactured by Diodes Incorporated in an 8-SOIC surface mount package. This component is classified as obsolete, making identification of functional equivalents essential for ongoing design support and production continuity. The part operates across a 9V to 21V supply range and is designed for single-output LED driving applications with offline switching topology. Due to its obsolete status, equivalent parts from active product lines are necessary for new designs and long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP1682MTR-OG1 is determined by the following critical parameters:

Primary Matching Criteria:

• AC DC offline switcher topology
• Single output configuration
• Surface mount or through-hole packaging compatibility
• Operating temperature range capability
• RoHS3 compliance and MSL rating

Substitution Logic: Equivalent parts are grouped into two categories based on packaging and electrical characteristics. The parametric equivalent AP1682MTR-G1 maintains identical electrical specifications and 8-SOIC packaging, providing direct substitution. Manufacturer-recommended alternatives (HV9922N3-G, MP4088GN, TPS92074D) offer functional equivalence through AC DC offline switching topology but may differ in supply voltage ranges, internal switch configuration, topology classification, and package form factor. These alternatives are suitable when the specific voltage and switching characteristics align with application requirements.

Parameter Comparison

Engineering Selection Recommendations

AP1682MTR-G1 is the direct parametric equivalent, maintaining identical electrical specifications, supply voltage range (9V to 21V), and 8-SOIC packaging. Both parts are obsolete; however, AP1682MTR-G1 offers higher inventory availability (25,200 pcs vs. 28,980 pcs). This part is suitable for immediate replacement in existing designs without modification.

HV9922N3-G (Microchip Technology) is an active product with extended supply voltage capability (20V to 400V) and integrated internal switching. The through-hole TO-92-3 package requires PCB layout modification. This part is suitable for designs requiring higher input voltage tolerance and triac dimming capability.

MP4088GN (Monolithic Power Systems) is an active product with buck-boost topology and triac dimming support. The 4.5V to 5V supply range differs significantly from the original specification and is suitable only for applications with compatible input voltage requirements. The 8-SOIC-EP package provides thermal management advantages.

TPS92074D (Texas Instruments) is an active product with buck-boost topology and supply range of 11V to 18V, overlapping the original 9V to 21V specification. The 8-SOIC package maintains form factor compatibility. This part is suitable for designs within the 11V to 18V operating window.

All substitute parts maintain ROHS3 compliance and are suitable for long-term production use based on active product status.

Frequently Asked Questions (FAQ)

Q: Can AP1682MTR-G1 be used as a direct replacement for AP1682MTR-OG1?

A: Yes. AP1682MTR-G1 is a parametric equivalent with identical electrical specifications, supply voltage range (9V to 21V), and 8-SOIC packaging. No design modifications are required.

Q: What is the primary difference between the AP1682MTR-OG1 and the manufacturer-recommended alternatives?

A: The main differences are product status (obsolete vs. active), supply voltage ranges, internal switch configuration, and package form factors. HV9922N3-G uses through-hole packaging; MP4088GN operates at 4.5V to 5V; TPS92074D operates at 11V to 18V.

Q: Is the HV9922N3-G suitable for the same PCB layout as the AP1682MTR-OG1?

A: No. HV9922N3-G uses TO-92-3 through-hole packaging, while AP1682MTR-OG1 uses 8-SOIC surface mount. PCB layout modification is required.

Q: Which substitute part has the widest supply voltage range?

A: HV9922N3-G operates across 20V to 400V, providing the widest input voltage tolerance among all listed alternatives.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (AP1682MTR-G1, HV9922N3-G, MP4088GN, TPS92074D) are ROHS3 compliant.

Q: What is the MSL rating difference between MP4088GN and other alternatives?

A: MP4088GN has an MSL rating of 2A (4 weeks), while AP1682MTR-OG1, AP1682MTR-G1, HV9922N3-G, and TPS92074D all have MSL rating 1 (unlimited). This affects moisture sensitivity handling during storage and assembly.

Q: Can TPS92074D be used in applications requiring the full 9V to 21V supply range?

A: TPS92074D operates at 11V to 18V, which overlaps but does not cover the full 9V to 21V range. It is suitable only for applications operating within the 11V to 18V window.
