Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the PS2806-1 is determined by the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Isolation: 2500Vrms
• Number of Channels: 1
• Output Type: Darlington
• Current Transfer Ratio (Min): 200% @ 1mA
• Voltage - Output (Max): 40V
• Current - Output / Channel: 90mA
• Operating Temperature Range: -55°C ~ 100°C
• Input Type: AC, DC capable

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package footprint compatibility: 4-SOIC (0.173", 4.40mm Width)

The PS2806-1-F3-A, manufactured by Renesas Electronics Corporation, maintains electrical equivalence across all primary isolation, output, and input specifications while providing compatibility with surface mount assembly processes. Both parts belong to the NEPOC series and are characterized as optoisolators within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs: The PS2806-1-F3-A serves as an electrical and mechanical equivalent for the obsolete PS2806-1. Both components are rated for identical isolation voltage, output characteristics, and operating temperature specifications. The primary distinction is product status and compliance posture: the PS2806-1 is Obsolete with RoHS non-compliance, while the PS2806-1-F3-A is classified as "Not For New Designs" and achieves ROHS3 compliance.

For New Designs: Neither component is recommended for new design integration. The PS2806-1 is obsolete, and the PS2806-1-F3-A is marked "Not For New Designs." Alternative optoisolator solutions from active product lines should be evaluated for new circuit development.

Compliance Considerations: The PS2806-1-F3-A provides improved compliance status (ROHS3 Compliant vs. RoHS non-compliant) and REACH Unaffected status, making it preferable for applications with environmental or regulatory requirements when legacy design continuity is necessary.

Frequently Asked Questions (FAQ)

Q: Can the PS2806-1-F3-A replace the PS2806-1 in existing assemblies? A: Electrical substitution is feasible based on identical isolation voltage, output current rating, transfer ratio, temperature range, and equivalent package footprint. Both parts maintain 2500Vrms isolation, 90mA output capability, and 4-SOIC package dimensions.

Q: What is the difference between the 4-SOP and 4-SSOP package designations? A: The supplier device package designation differs (4-SOP vs. 4-SSOP); however, both maintain the same physical 4-SOIC (0.173", 4.40mm Width) footprint suitable for surface mount assembly processes.

Q: Should I use the PS2806-1-F3-A for new circuit designs? A: No. The PS2806-1-F3-A is classified as "Not For New Designs." For new development, optoisolators from active product lines with full production support should be selected.

Q: What compliance advantages does the PS2806-1-F3-A offer? A: The PS2806-1-F3-A achieves ROHS3 compliance and REACH Unaffected status, whereas the PS2806-1 is RoHS non-compliant and REACH Affected. This makes the F3-A variant preferable for applications with environmental or regulatory compliance requirements.

Q: Are the electrical characteristics identical between the two parts? A: Electrical specifications are identical across isolation voltage (2500Vrms), current transfer ratio (200% @ 1mA), output voltage (40V max), output current (90mA), operating temperature (-55°C to 100°C), and switching characteristics (200µs rise/fall time).
