Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ORNTA5000CT1 is determined by strict equivalence across the following critical parameters:

• Resistance value: 500 Ohm (exact match required)
• Number of resistors: 4 elements (exact match required)
• Circuit topology: Isolated configuration (exact match required)
• Power rating: 100mW per element (exact match required)
• Package type: 8-SOIC form factor with identical physical dimensions (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Environmental compliance: RoHS3 and REACH status (exact match required)

The ORNTA5000AT1 qualifies as a direct substitute based on full alignment with these parameters. Tolerance and matching ratio specifications differ but do not preclude substitution; the substitute part offers tighter tolerance (±0.1% versus ±0.25%) and improved matching ratio (±0.05% versus ±0.1%), representing enhanced electrical performance within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

Both ORNTA5000CT1 and ORNTA5000AT1 maintain Active product status with identical environmental compliance certifications (RoHS3 Compliant, REACH Unaffected). Selection between these parts is based on tolerance and matching requirements specific to the application circuit. The ORNTA5000CT1 is appropriate for general-purpose resistor network applications where ±0.25% tolerance and ±0.1% matching ratio meet circuit specifications. The ORNTA5000AT1 is suitable for precision analog applications requiring tighter tolerance control (±0.1%) and superior resistor matching (±0.05%), while maintaining identical thermal performance and operating range. Both parts are qualified for the same environmental conditions and offer equivalent mechanical compatibility in 8-SOIC surface mount implementations.

Frequently Asked Questions (FAQ)

Q: Can ORNTA5000AT1 be used as a direct replacement for ORNTA5000CT1?

A: Yes. Both parts share identical resistance value, package type, pin count, power rating, temperature range, and environmental compliance. The ORNTA5000AT1 offers improved tolerance and matching specifications, making it functionally compatible for any application designed around the ORNTA5000CT1.

Q: What are the key differences between these two parts?

A: The primary differences are tolerance and matching ratio. ORNTA5000CT1 specifies ±0.25% tolerance with ±0.1% matching ratio, while ORNTA5000AT1 specifies ±0.1% tolerance with ±0.05% matching ratio. All other electrical and mechanical parameters are identical.

Q: Are there any package or pinout differences?

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 PCB footprint compatibility is guaranteed.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both ORNTA5000CT1 and ORNTA5000AT1 are RoHS3 Compliant, REACH Unaffected, with Moisture Sensitivity Level 1 (Unlimited). Both operate across -55°C ~ 125°C temperature range.

Q: Which part should I select for a precision measurement circuit?

A: Selection depends on circuit tolerance requirements. For applications requiring tighter tolerance control and superior resistor matching, ORNTA5000AT1 is the appropriate choice. For general-purpose applications, ORNTA5000CT1 is suitable.
