Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPMT1002FT1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance values: 5kΩ, 5kΩ
• Circuit type: Voltage Divider
• Number of resistors: 2
• Number of pins: 3
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±1% or better)
• Resistor matching ratio: May be equal or tighter (±0.5% or better)
• Temperature coefficient: May be equal or lower in absolute value (±25ppm/°C or better)
• Power per element: May be equal or higher (100mW or greater)

The MPMT1002AT1 qualifies as a direct substitute because it maintains all mandatory parameters while offering improved tolerance (±0.1% vs ±1%) and matching ratio (±0.05% vs ±0.5%), making it suitable for applications requiring higher precision.

Parameter Comparison

Engineering Selection Recommendations

Both MPMT1002FT1 and MPMT1002AT1 are active products manufactured by Vishay Dale Thin Film and comply with ROHS3 and REACH requirements. Selection between these parts depends on application tolerance requirements:

• MPMT1002FT1 is suitable for general-purpose voltage divider applications where ±1% tolerance and ±0.5% matching ratio are acceptable.
• MPMT1002AT1 is suitable for precision voltage divider applications requiring tighter tolerance (±0.1%) and superior matching ratio (±0.05%).

Both parts are pin-compatible, package-compatible, and thermally equivalent. The SOT-23 package footprint is identical for both parts, enabling direct PCB substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can MPMT1002AT1 replace MPMT1002FT1 in existing designs?

A: Yes. The MPMT1002AT1 is electrically and mechanically compatible with MPMT1002FT1. It maintains identical resistance values, pin configuration, package dimensions, and operating temperature range. The tighter tolerance and matching ratio of MPMT1002AT1 make it a direct substitute that will not degrade circuit performance.

Q: What is the difference between these two parts?

A: The primary differences are tolerance and matching ratio. MPMT1002FT1 has ±1% tolerance and ±0.5% matching ratio, while MPMT1002AT1 has ±0.1% tolerance and ±0.05% matching ratio. All other electrical and mechanical parameters are identical.

Q: Are the packages identical?

A: Yes. Both parts use the TO-236-3 / SC-59 / SOT-23-3 package with identical footprint dimensions (0.113" L × 0.051" W, 2.86mm × 1.30mm) and maximum seated height (0.044" / 1.12mm). No PCB layout changes are required for substitution.

Q: Do these parts have the same temperature coefficient?

A: Yes. Both MPMT1002FT1 and MPMT1002AT1 have a temperature coefficient of ±25ppm/°C and resistor-ratio-drift of ±2ppm/°C, ensuring identical thermal performance across the -55°C to 125°C operating range.

Q: Which part should I use for a precision voltage divider circuit?

A: MPMT1002AT1 is recommended for precision applications due to its ±0.1% tolerance and ±0.05% matching ratio, which provide superior voltage divider accuracy compared to MPMT1002FT1.
