Key Parameters

Substitute Part Grouping Explanation

Substitution of the KA2807DTF is determined by the following critical parameters:

• Functional Category: Earth Leakage Detector PMIC
• Manufacturer: onsemi (same manufacturer ensures design compatibility)
• Base Product Number: KA2807 (indicates same functional core)
• Supply Current: 19mA (electrical performance requirement)
• Operating Temperature Range: -40°C ~ 70°C (environmental specification)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Compliance: ROHS3 Compliant, REACH Unaffected (regulatory alignment)

The KA2807MUX qualifies as a substitute based on matching the base product number, identical electrical specifications, and equivalent functional performance within the same product family.

Parameter Comparison

Engineering Selection Recommendations

Both the KA2807DTF and KA2807MUX are obsolete products from onsemi's KA2807 product family. Selection between these parts is determined by package compatibility with existing PCB designs:

• KA2807DTF: Use when 8-SOIC (0.154", 3.90mm Width) package footprint is required
• KA2807MUX: Use when 8-MSOP (0.118", 3.00mm Width) package footprint is required

Both parts maintain identical electrical performance, supply current specifications, operating temperature ranges, and regulatory compliance status. The primary differentiation is package geometry and board-level footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can KA2807MUX replace KA2807DTF directly on a PCB?

A: Direct replacement depends on package footprint compatibility. The KA2807DTF uses an 8-SOIC package (0.154" width), while the KA2807MUX uses an 8-MSOP package (0.118" width). PCB layout modifications are required if switching between these packages.

Q: Are the electrical specifications identical between KA2807DTF and KA2807MUX?

A: Yes. Both parts share the same base product number (KA2807), supply current (19mA), operating temperature range (-40°C ~ 70°C), and functional application as Earth Leakage Detector PMICs.

Q: What is the significance of both parts being obsolete?

A: Obsolete status indicates these products are no longer in active production. Existing inventory from authorized distributors represents the available supply. Long-term availability should be confirmed with component suppliers.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both KA2807DTF and KA2807MUX are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: How does package size affect component selection?

A: Package size determines PCB footprint compatibility. The 8-SOIC package is wider (0.154") than the 8-MSOP package (0.118"), affecting board layout, trace routing, and component density. Selection must align with existing PCB design specifications.
