Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP3801DH-LF-Z is determined by strict alignment across the following critical parameters:

• Device Type: Must be an EL Lamp Driver controller
• Frequency Range: Must support 50kHz ~ 200kHz operation
• Supply Voltage: Must operate within 2.5V ~ 5.5V range
• Package Configuration: Must use 8-MSOP-EP (8-TSSOP, 8-MSOP with Exposed Pad)
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must support -40°C ~ 85°C
• Regulatory Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The MP3802DH-LF-Z qualifies as a direct substitute based on full alignment across all critical parameters. The primary distinction is the MP3802DH-LF-Z carries Active product status, whereas the MP3801DH-LF-Z is Not For New Designs.

Engineering Selection Recommendations

The MP3802DH-LF-Z is the qualified substitute for the MP3801DH-LF-Z. Selection between these parts should be based on the following criteria:

For Legacy System Support: The MP3801DH-LF-Z remains available with 44,620 units in stock. Use this part number when exact design continuity is required for existing production or field service applications.

For New Production and Ongoing Designs: The MP3802DH-LF-Z is the recommended choice. It maintains identical electrical and mechanical specifications while carrying Active product status from the manufacturer. With 10,270 units in stock, it provides long-term supply assurance and aligns with current manufacturing practices.

Compliance Considerations: Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating. No additional qualification is required when transitioning between these parts in compliant supply chains.

Pin-for-Pin Compatibility: Both parts use the 8-MSOP-EP package with identical pinout and thermal characteristics, enabling direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the MP3802DH-LF-Z be used as a direct replacement for the MP3801DH-LF-Z on existing PCBs?

A: Yes. Both parts use the 8-MSOP-EP package with identical pinout, dimensions (0.118", 3.00mm width), and thermal pad configuration. No PCB modifications are required.

Q: What is the significance of the "Not For New Designs" status on the MP3801DH-LF-Z?

A: This designation indicates the manufacturer has transitioned this part to legacy support status. The MP3802DH-LF-Z is the active successor. For new product development, the MP3802DH-LF-Z should be specified.

Q: Are there any electrical differences between these parts?

A: Both parts operate identically across all critical parameters: frequency range (50kHz ~ 200kHz), supply voltage (2.5V ~ 5.5V), operating temperature (-40°C ~ 85°C), and dimming capability (No). The MP3802DH-LF-Z specifies a supply current of 100 µA, which was not documented for the MP3801DH-LF-Z.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. No additional certifications or qualifications are needed when substituting between these parts.

Q: Which part should be selected for a new EL lamp driver application?

A: The MP3802DH-LF-Z should be selected for new designs. It provides the same functional performance as the MP3801DH-LF-Z while maintaining active manufacturer support and current production status.

Q: Is the package footprint identical between both parts?

A: Yes. Both parts use the 8-TSSOP, 8-MSOP package with 0.118" width, 3.00mm body width, and exposed pad configuration. Footprints are interchangeable.
