PS2802-1-F3-L-A Equivalent & Substitute Parts

Part Overview

The PS2802-1-F3-L-A is an optoisolator with Darlington output, rated for 2500Vrms isolation voltage, designed for single-channel galvanic isolation applications. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design and production requirements. Substitute parts must maintain electrical and mechanical compatibility within the 4-SOIC package while meeting isolation and output specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity for optoisolators is determined by equivalence across electrical isolation characteristics and output specifications. The critical parameters for PS2802-1-F3-L-A substitution are:

• Isolation Voltage: 2500Vrms (non-negotiable for safety-critical isolation requirements)
• Output Type & Configuration: Darlington output, single channel
• Package / Case: 4-SOIC form factor for direct PCB compatibility
• Output Electrical Ratings: Maximum output voltage (40V), output current (90mA), saturation voltage (1V)
• Operating Temperature Range: -55°C to 100°C
• Regulatory Compliance: ROHS3 compliance and REACH status

The identified substitute parts PS2802-1-A and PS2802-1-F3-A are members of the same NEPOC series with identical mechanical and primary isolation specifications. Variations in Current Transfer Ratio minimums are within acceptable tolerance bands for this product category.

Parameter Comparison

Engineering Selection Recommendations

PS2802-1-F3-A is the primary recommended substitute. This part maintains active product status with production allocation (26,499 pieces in stock), ensuring long-term supply continuity. Full ROHS3 compliance and REACH unaffected status satisfy regulatory requirements. The lower Current Transfer Ratio minimum (200% vs. 700%) operates within acceptable parametric margins for Darlington optoisolator applications and does not compromise circuit performance when output current requirements remain within the 90mA specification.

PS2802-1-A provides an alternative substitute with equivalent electrical specifications but carries a "Not For New Designs" status from the manufacturer. This designation limits its suitability for new production unless legacy system maintenance is the sole application driver. Inventory availability (1,772 pieces) supports short-to-medium term supply requirements.

Frequently Asked Questions (FAQ)

Q: Can PS2802-1-A or PS2802-1-F3-A be used as direct replacements for PS2802-1-F3-L-A on existing PCBs?

A: Yes. All three parts share identical 4-SOIC packaging, pinout, and electrical specifications within critical isolation (2500Vrms) and output parameters (40V max, 90mA per channel). Direct socket replacement is mechanically and electrically valid.

Q: Why do PS2802-1-A and PS2802-1-F3-A specify a lower Current Transfer Ratio minimum (200% vs. 700%)?

A: Current Transfer Ratio variations within the same product family reflect manufacturer grading and binning practices. The 200% minimum still satisfies isolation gate-drive and logic-level interface requirements. Designs relying on the original 700% specification require circuit-level validation of the lower ratio's impact on switching performance and timing margins.

Q: What is the difference between PS2802-1-F3-A and PS2802-1-A?

A: Both parts are electrically identical. The primary distinction is product status: PS2802-1-F3-A carries "Active" designation with higher inventory levels, while PS2802-1-A is marked "Not For New Designs." For new designs, PS2802-1-F3-A is the preferred choice.

Q: Are there packaging format differences between these parts?

A: PS2802-1-F3-L-A uses standard packaging (format unspecified in data). PS2802-1-A is supplied in Strip format. PS2802-1-F3-A is available in Cut Tape (CT) and Digi-Reel formats. All three use identical 4-SOIC component packaging; the listed formats refer to tape and reel carrier configurations for production handling.

Q: How do ROHS3 compliance and REACH unaffected status affect substitution eligibility?

A: All three parts maintain ROHS3 compliance and REACH unaffected status, confirming compatibility with environmental and chemical restriction directives applicable to electronic components in the European Union and equivalent regulatory jurisdictions.
