Key Parameters

Substitute Part Grouping Explanation

Substitution for the ORNA2001AT1 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2kΩ
• Tolerance: ±0.1%
• Circuit configuration: Isolated 4-resistor network
• Package type: 8-SOIC with identical physical dimensions
• Power rating: 100mW per element minimum
• Temperature coefficient: ±25ppm/°C
• Resistor matching ratio: ±0.05%
• Operating temperature range: -55°C to 125°C

The ORNTA2001AT1 meets all these criteria and is classified as a direct equivalent within the Vishay Dale Thin Film ORN series.

Parameter Comparison

Engineering Selection Recommendations

Both ORNA2001AT1 and ORNTA2001AT1 are active production parts from Vishay Dale Thin Film with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: ORNA2001AT1 is RoHS non-compliant, while ORNTA2001AT1 is ROHS3 compliant. Selection between these parts should be based on regulatory requirements for the end application. Both parts maintain equivalent performance across all specified parameters and are suitable for direct substitution where compliance requirements permit.

Frequently Asked Questions (FAQ)

Q: Can ORNTA2001AT1 replace ORNA2001AT1 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The ORNTA2001AT1 variant offers ROHS3 compliance, making it suitable for applications with RoHS requirements.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 8-SOIC package with identical physical dimensions (0.194" L x 0.157" W, 4.93mm x 3.99mm) and maximum seated height of 0.068" (1.73mm). Pinout and footprint are identical.

Q: What determines substitutability for this resistor network?

A: Substitutability is determined by matching resistance value (2kΩ), tolerance (±0.1%), circuit configuration (isolated 4-resistor network), package type (8-SOIC), power rating (100mW per element), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C to 125°C).

Q: Is the resistor matching ratio critical for substitution?

A: Yes. The ±0.05% resistor matching ratio and ±5ppm/°C ratio drift are precision parameters that must be maintained for functional equivalence in applications requiring matched resistor networks.

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

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