Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPM1003AT1 is determined by strict equivalence across the following critical parameters:

• Resistance values: Both resistors must be 50kΩ
• Tolerance specification: ±0.1% maximum tolerance
• Resistor matching ratio: ±0.05% or better
• Temperature coefficient: ±25ppm/°C or better
• Power rating: 100mW per element minimum
• Package type: SOT-23 (TO-236-3, SC-59, SOT-23-3)
• Pin count: 3-pin configuration
• Circuit topology: Voltage divider network

The MPMT1003AT1 meets all electrical and mechanical substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The MPMT1003AT1 is a direct functional equivalent to the MPM1003AT1 with identical electrical specifications and mechanical compatibility. Both parts are active products from Vishay Dale Thin Film and maintain the same SOT-23 package footprint, pin configuration, and performance characteristics.

The primary distinction between these parts is regulatory compliance status. The MPMT1003AT1 is ROHS3 compliant, while the MPM1003AT1 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the MPMT1003AT1 is the appropriate selection. Both parts maintain identical REACH and ECCN classifications.

Selection between these parts should be based on compliance requirements specific to the end application and regional regulations governing the final product assembly and distribution.

Frequently Asked Questions (FAQ)

Q: Are MPM1003AT1 and MPMT1003AT1 electrically interchangeable?

A: Yes. Both parts feature identical resistance values (50kΩ, 50kΩ), tolerance (±0.1%), matching ratio (±0.05%), temperature coefficient (±25ppm/°C), power rating (100mW per element), and operating temperature range (-55°C ~ 125°C). Electrical performance is equivalent.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use the SOT-23 package with identical dimensions (0.113" L x 0.051" W, 2.86mm x 1.30mm) and maximum seated height (0.044", 1.12mm). Pin configuration and footprint are identical, allowing direct substitution without PCB redesign.

Q: What is the difference between MPM1003AT1 and MPMT1003AT1?

A: The MPMT1003AT1 is ROHS3 compliant, while the MPM1003AT1 is RoHS non-compliant. All other specifications, including electrical performance, package type, and mechanical dimensions, are identical.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, specify MPMT1003AT1. For applications without RoHS requirements, either part is acceptable based on availability and cost considerations.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts maintain identical temperature coefficients (±25ppm/°C), resistor-ratio-drift (±2ppm/°C), and operating temperature ranges (-55°C ~ 125°C). Thermal performance and long-term stability are equivalent.

Q: What is the moisture sensitivity level for these parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
