Engineering Selection Recommendations

Primary Recommendation: PS2802-1-F3-A

The PS2802-1-F3-A represents the optimal substitution path for the obsolete PS2802-1-F3. This part offers identical electrical parameters, mechanical compatibility, and packaging configuration. Notably, PS2802-1-F3-A carries Active product status with ROHS3 compliance and REACH Unaffected designation, eliminating regulatory constraints present in the original part. Inventory availability of 26499 units supports production volume requirements.

Secondary Recommendation: PS2802-1-V-F3-A

The PS2802-1-V-F3-A provides parametric equivalence with Active product status, ROHS3 compliance, and REACH Unaffected status. This variant is supplied in Tape & Reel format with substantial inventory (4466 units), suitable for automated assembly operations.

Alternative for Enhanced Current Transfer Ratio: PS2802-1-M-A

For designs requiring current transfer ratio specification with defined maximum range (200% to 1000%), PS2802-1-M-A offers superior characterization with all other parameters matching the original part. This variant maintains Active status and ROHS3 compliance.

Not Recommended: PS2802-1-A

Although PS2802-1-A provides electrical equivalence, its Not For New Designs status disqualifies it from selection in new development activities.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically identical to the PS2802-1-F3?

A: Electrical functionality is identical across all listed substitutes with respect to isolation voltage, output configuration, operating temperature range, and switching characteristics. Parts designated as "Similar" (PS2802-1-F3-K-A, PS2802-1-K-A) feature elevated minimum current transfer ratio of 2000% @ 1mA versus 200% @ 1mA. PS2802-1-M-A provides current transfer ratio specification with a defined maximum of 1000% @ 1mA, enabling tighter performance characterization.

Q: Can the PS2802-1-F3-A serve as a direct replacement in existing designs?

A: Yes. The PS2802-1-F3-A maintains electrical compatibility, mechanical equivalence, and identical 4-SOIC package dimensions, enabling direct substitution in existing circuit layouts and component placement programs.

Q: What compliance advantages do the substitute parts offer?

A: All recommended substitutes achieve ROHS3 compliance, whereas the original PS2802-1-F3 is RoHS non-compliant. Additionally, PS2802-1-F3-A and PS2802-1-V-F3-A carry REACH Unaffected designation, eliminating regulatory notification requirements. This addresses compliance requirements for manufacturing into restricted jurisdictions.

Q: Does packaging format differ among the substitutes?

A: Packaging options vary: PS2802-1-F3-A is supplied in Cut Tape format; PS2802-1-V-F3-A is provided in Tape & Reel; PS2802-1-A is available in Strip configuration. All maintain identical 4-SOIC package dimensions. Tape & Reel format (PS2802-1-V-F3-A) is optimized for high-speed automated assembly environments.

Q: What is the significance of the current transfer ratio variations among similar parts?

A: Current transfer ratio defines the output collector current per unit of input LED current. Minimum rating of 200% ensures reliable operation across process variations and temperature extremes. Elevated minimum rating of 2000% (PS2802-1-F3-K-A, PS2802-1-K-A) provides enhanced design margin for switching applications. PS2802-1-M-A's maximum specification of 1000% @ 1mA enables tighter performance characterization for precision isolation applications.

Q: Which substitute offers the best inventory availability?

A: PS2802-1-F3-A offers the highest stock level at 26499 units, supporting immediate availability for production requirements. PS2802-1-V-F3-A provides secondary availability at 4466 units.
