Substitute Part Grouping Explanation

Substitution eligibility for the MPMT5000BT1 is determined by the following critical parameters:

• Resistance values: 250Ω, 250Ω configuration
• Tolerance: ±0.1% or tighter
• Number of resistors: 2-element network
• Power rating: 100mW per element minimum
• Temperature coefficient: ±25ppm/°C or better
• Package: TO-236-3 / SOT-23-3 form factor
• Pin count: 3-pin configuration
• Operating temperature: -55°C to 125°C minimum range
• Compliance: RoHS3 and REACH status

The MPMT5000AT1 qualifies as a direct substitute based on identical electrical specifications, matching mechanical packaging, and equivalent environmental compliance ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the MPMT5000BT1 and MPMT5000AT1 are active production parts with identical compliance certifications. The MPMT5000AT1 offers improved resistor matching ratio of ±0.05% compared to the MPMT5000BT1 at ±0.1%, providing tighter inter-resistor tolerance for applications requiring enhanced matching precision. Both parts maintain equivalent temperature stability, power handling, and environmental compliance across the full operating range.

Selection between these parts depends on the specific matching tolerance requirement of the application circuit. For applications where the ±0.1% matching ratio of the MPMT5000BT1 is sufficient, either part is functionally equivalent. For circuits requiring superior matching performance, the MPMT5000AT1 is the preferred selection.

Frequently Asked Questions (FAQ)

Q: Can MPMT5000AT1 replace MPMT5000BT1 in existing designs?

A: Yes. Both parts share identical resistance values, power ratings, temperature coefficients, operating temperature range, and SOT-23-3 package dimensions. The MPMT5000AT1 provides equal or superior performance with tighter resistor matching.

Q: What is the difference between these two parts?

A: The primary difference is resistor matching ratio. MPMT5000BT1 specifies ±0.1% matching, while MPMT5000AT1 specifies ±0.05% matching. All other electrical and mechanical parameters are identical.

Q: Are the packages physically interchangeable?

A: Yes. Both parts use the TO-236-3 / SOT-23-3 package with identical dimensions: 0.113" L x 0.051" W (2.86mm x 1.30mm) and maximum seated height of 0.044" (1.12mm). PCB footprints are compatible.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both MPMT5000BT1 and MPMT5000AT1 are RoHS3 compliant, REACH unaffected, with MSL rating of 1 (unlimited moisture sensitivity).

Q: Which part should I specify for new designs?

A: Selection depends on matching tolerance requirements. If ±0.1% resistor matching is acceptable, either part is suitable. For applications requiring ±0.05% matching precision, specify MPMT5000AT1.
