OSOPTA1002CT1 Equivalent & Substitute Parts

Part Overview

The OSOPTA1002CT1 is a 10-resistor network array manufactured by Vishay Dale Thin Film in the OSOP series. This isolated resistor array contains ten 10kΩ resistors with ±0.25% tolerance, rated at 100mW per element, and packaged in a 20-pin SSOP surface mount configuration. The component is active in production status and ROHS3 compliant, making it suitable for precision analog and mixed-signal circuit applications requiring matched resistor networks. Equivalent and substitute parts are identified to support design flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSOPTA1002CT1 is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ (exact match required)
• Number of resistors: 10 (exact match required)
• Circuit type: Isolated (exact match required)
• Package / Case: 20-SSOP (exact match required)
• Power per element: 100mW (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Mounting type: Surface Mount (exact match required)

The OSOPTA1002AT1 qualifies as a direct substitute because it maintains identical values for all critical parameters. The primary distinction is an improved tolerance specification (±0.1% versus ±0.25%) and enhanced resistor matching ratio (±0.05% versus ±0.1%), which represent performance upgrades rather than functional incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

Both the OSOPTA1002CT1 and OSOPTA1002AT1 are active production components from Vishay Dale Thin Film and maintain full ROHS3 compliance. The OSOPTA1002AT1 offers tighter tolerance (±0.1% versus ±0.25%) and improved resistor matching ratio (±0.05% versus ±0.1%), making it suitable for applications requiring higher precision. The OSOPTA1002CT1 remains appropriate for applications where the ±0.25% tolerance specification is sufficient. Both components share identical package geometry, pin count, power rating, temperature coefficient, and operating temperature range, ensuring direct functional interchangeability at the circuit board level.

Frequently Asked Questions (FAQ)

Q: Can the OSOPTA1002AT1 replace the OSOPTA1002CT1 in existing designs?

A: Yes. The OSOPTA1002AT1 is a direct substitute with identical electrical and mechanical specifications except for improved tolerance and matching ratio. No circuit modifications or PCB layout changes are required.

Q: What is the primary difference between these two parts?

A: The OSOPTA1002AT1 provides tighter tolerance (±0.1% versus ±0.25%) and better resistor matching ratio (±0.05% versus ±0.1%). All other parameters, including resistance value, power rating, package, and temperature range, are identical.

Q: Are both parts available in the same packaging format?
