Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP6901DS-LF is determined by the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 8-SOIC (0.154", 3.90mm Width) package to ensure PCB layout compatibility and automated assembly feasibility.
• Functional Classification: Both parts must operate as secondary-side controllers within power supply applications.
• Supply Voltage Range: The substitute must accommodate the system's supply voltage requirements. The MP6901DS-LF operates at 8V ~ 24V; substitutes with extended or overlapping ranges are acceptable.
• Mounting Type: Surface-mount technology must be maintained for manufacturing consistency.
• Regulatory Compliance: RoHS3 compliance is mandatory for equivalent parts in regulated markets.

The TEA1761T/N2/DG,118 meets these substitution criteria through identical package geometry, matching functional application, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the MP6901DS-LF and TEA1761T/N2/DG,118 are active products with identical RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future market requirements. The TEA1761T/N2/DG,118 offers an extended supply voltage range (8.6V ~ 38V versus 8V ~ 24V) and superior moisture sensitivity classification (MSL 1 Unlimited versus MSL 2 1 Year), providing enhanced environmental robustness. Both devices maintain EAR99 export classification and identical HTSUS coding. Selection between these parts should be based on specific application voltage requirements and environmental storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the TEA1761T/N2/DG,118 be used as a direct replacement for the MP6901DS-LF?

A: Yes, provided the application's supply voltage requirement falls within the TEA1761T/N2/DG,118 operating range of 8.6V ~ 38V. Both devices share identical 8-SOIC package geometry and surface-mount configuration, enabling direct PCB substitution without layout modifications.

Q: What are the key differences between these two parts?

A: The primary differences are supply voltage range (MP6901DS-LF: 8V ~ 24V; TEA1761T/N2/DG,118: 8.6V ~ 38V), supply current (3 mA versus 1 mA), operating temperature range (-40°C ~ 125°C versus -20°C ~ 150°C), and moisture sensitivity level (MSL 2 versus MSL 1). The TEA1761T/N2/DG,118 provides extended voltage capability and improved moisture resistance.

Q: Are there packaging differences between these parts?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) package. The main part is supplied in Tube packaging, while the substitute is supplied in Tape & Reel format. This difference affects only procurement and handling; the physical component dimensions and pin configuration are identical.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the MP6901DS-LF and TEA1761T/N2/DG,118 are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes, meeting current regulatory standards for electronics manufacturing and distribution.

Q: Which part should be selected for high-temperature applications?

A: The TEA1761T/N2/DG,118 supports an operating temperature range up to 150°C, compared to 125°C for the MP6901DS-LF, making it suitable for applications requiring extended high-temperature operation.
