• Package: 20-SSOP with identical physical dimensions (0.344" L × 0.154" W, 1.73mm max height)
• Pin count: 20
• Power rating: 100mW per element
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C to 125°C
• Mounting: Surface mount

The OSOPTA5001AT1 meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both OSOPA5001AT1 and OSOPTA5001AT1 are electrically and mechanically equivalent and suitable for direct substitution in circuit applications. Selection between these parts should be based on the following criteria:

OSOPA5001AT1 is appropriate for applications where RoHS compliance is not a requirement or where legacy component specifications are mandated.

OSOPTA5001AT1 is the preferred selection for new designs and applications requiring ROHS3 compliance. This variant maintains identical electrical performance and physical characteristics while meeting current environmental and regulatory standards. The OSOPTA5001AT1 also offers superior inventory availability (5431 pcs vs. 916 pcs).

Both parts are manufactured by Vishay Dale Thin Film and carry Active product status, ensuring continued supply and technical support.

Frequently Asked Questions (FAQ)

Q: Can OSOPTA5001AT1 be used as a direct replacement for OSOPA5001AT1?

A: Yes. The OSOPTA5001AT1 is electrically and mechanically equivalent to the OSOPA5001AT1. All critical parameters including resistance value, tolerance, power rating, temperature coefficient, package dimensions, and pin configuration are identical. The parts are pin-for-pin compatible and require no circuit modifications.

Q: What is the difference between OSOPA5001AT1 and OSOPTA5001AT1?

A: The primary difference is RoHS compliance status. OSOPA5001AT1 is RoHS non-compliant, while OSOPTA5001AT1 is ROHS3 compliant. Electrical specifications, physical dimensions, and performance characteristics are identical. The OSOPTA5001AT1 also has higher inventory availability.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 20-SSOP package with identical dimensions: 0.344" L × 0.154" W (8.74mm × 3.91mm), with a maximum seated height of 0.068" (1.73mm). PCB footprints and assembly processes are interchangeable.

Q: What is the resistor matching ratio difference between these parts?

A: OSOPA5001AT1 specifies a resistor matching ratio of ±0.025%, while OSOPTA5001AT1 specifies ±0.05%. Both values fall within acceptable tolerances for precision applications. Applications requiring the tighter ±0.025% matching should specify OSOPA5001AT1.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both OSOPA5001AT1 and OSOPTA5001AT1 are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the operating temperature range for these parts?

A: Both parts operate across -55°C to 125°C with a temperature coefficient of ±25ppm/°C, ensuring stable performance across industrial and extended temperature applications.
