Substitute Part Grouping Explanation

Substitution eligibility for the ORNA5000AT1 is determined by strict equivalence across the following critical parameters:

• Resistance value: 500 Ohms
• Tolerance specification: ±0.1%
• Circuit configuration: Isolated 4-resistor network
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Power rating per element: 100mW
• Temperature coefficient: ±25ppm/°C
• Resistor matching ratio: ±0.05%
• Resistor-ratio-drift: ±5ppm/°C
• Pin count: 8
• Operating temperature range: -55°C ~ 125°C

The substitute part ORNTA5000AT1 meets all electrical and mechanical specifications required for direct substitution. Both parts are manufactured by Vishay Dale Thin Film within the ORN series and share identical functional parameters.

Parameter Comparison

Engineering Selection Recommendations

Both ORNA5000AT1 and ORNTA5000AT1 are active production parts from Vishay Dale Thin Film with identical electrical and mechanical specifications. The ORNTA5000AT1 variant carries ROHS3 compliance certification, whereas the ORNA5000AT1 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements and end-application compliance mandates. Both parts maintain REACH Unaffected status and EAR99 export classification. For applications requiring RoHS3 compliance, ORNTA5000AT1 is the appropriate selection. For applications without RoHS compliance requirements, either part is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can ORNTA5000AT1 be used as a direct replacement for ORNA5000AT1?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including resistance value, tolerance, power rating, temperature coefficient, and package dimensions. The primary difference is RoHS compliance status.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: 500 Ohm resistance, ±0.1% tolerance, 4-resistor isolated configuration, 100mW power per element, ±25ppm/°C temperature coefficient, ±0.05% resistor matching ratio, 8-SOIC package, and -55°C to 125°C operating range.

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

A: No. Both parts use identical 8-SOIC (0.154", 3.90mm Width) packaging with 8 pins, identical physical dimensions of 0.194" L x 0.157" W (4.93mm x 3.99mm), and identical maximum seated height of 0.068" (1.73mm).

Q: What is the difference in RoHS compliance between these parts?

A: ORNA5000AT1 is RoHS non-compliant, while ORNTA5000AT1 is ROHS3 compliant. Selection depends on application regulatory requirements.

Q: Are both parts suitable for the full operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C with matching temperature coefficient specifications of ±25ppm/°C.
