Substitute Part Grouping Explanation

Substitute parts for the PS2801C-4-F3-A are classified into two categories based on parametric equivalence and functional compatibility:

Parametric Equivalents (Direct Replacements): Parts that maintain identical or equivalent electrical specifications across isolation voltage, channel count, current transfer ratio, output voltage, output current, and saturation voltage. These parts are sourced from Renesas Electronics Corporation and share the PS2801 base product number with identical performance characteristics.

Functional Substitutes (Enhanced Performance): Parts that exceed the electrical specifications of the original component while maintaining compatible package footprints and mounting types. These substitutes provide higher isolation voltage ratings and improved switching performance.

Key Parameters Determining Substitution:

• Number of Channels: 4 (mandatory)
• Isolation Voltage: 2500Vrms minimum
• Output Type: Transistor
• Package Type: 16-SOIC / 16-SSOP surface mount
• Current Transfer Ratio: 50% minimum @ 5mA
• Output Current Capability: 30mA minimum per channel
• Vce Saturation: 300mV maximum

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent Selection (Renesas PS2801 Series):

The PS2801C-4-F3-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL part. This Renesas variant maintains identical electrical specifications including 2500Vrms isolation voltage, 4-channel configuration, 50-400% current transfer ratio, 80V maximum output voltage, and 30mA per-channel output current. The Renesas part carries Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring long-term availability and regulatory compliance.

The PS2801C-4-V-F3-A and PS2801C-4-V-A variants from Renesas are also parametric equivalents with identical electrical performance. These parts differ only in packaging format (Cut Tape & Digi-Reel versus Strip) and inventory levels. Selection between these three Renesas variants depends on procurement packaging requirements and supply chain logistics.

Functional Substitute Selection (Vishay TCMT4100):

The TCMT4100 from Vishay Semiconductor Opto Division functions as an enhanced substitute with superior isolation voltage rating (3750Vrms versus 2500Vrms) and higher output current capability (50mA versus 30mA per channel). The TCMT4100 maintains the 4-channel transistor output configuration, 16-SOIC package footprint, and surface mount compatibility. This part exhibits faster switching performance with reduced turn-on/turn-off times (6µs/5µs versus 10µs/7µs) and improved rise/fall times (3µs/4.7µs versus 5µs/7µs). The TCMT4100 carries Active product status with ROHS3 compliance. The operating temperature range is -40°C to 100°C, which is narrower than the original part's -55°C to 100°C range.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification consistent with the original PS2801C-4-F3-A. Moisture sensitivity level remains at MSL 1 (unlimited) across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can the Renesas PS2801C-4-F3-A directly replace the discontinued CEL PS2801C-4-F3-A?

A: Yes. The Renesas PS2801C-4-F3-A is a parametric equivalent with identical electrical specifications, package footprint (16-SOIC), and mounting type (surface mount). Both parts share the same isolation voltage (2500Vrms), channel count (4), current transfer ratio range (50-400% @ 5mA), output voltage (80V max), output current (30mA per channel), and saturation voltage (300mV max). The Renesas variant is currently in active production status.

Q: What are the differences between PS2801C-4-F3-A, PS2801C-4-V-F3-A, and PS2801C-4-V-A?

A: These three Renesas parts are parametric equivalents with identical electrical performance. The differences are packaging format and inventory availability. PS2801C-4-F3-A and PS2801C-4-V-F3-A are supplied in Cut Tape & Digi-Reel format, while PS2801C-4-V-A is supplied in Strip format. Selection depends on procurement requirements and assembly line compatibility.

Q: Is the Vishay TCMT4100 a direct replacement for the PS2801C-4-F3-A?

A: The TCMT4100 is a functional substitute, not a direct replacement. While it maintains the 4-channel configuration, transistor output type, and 16-SOIC package footprint, it provides enhanced specifications: 3750Vrms isolation voltage (versus 2500Vrms), 50mA output current per channel (versus 30mA), and faster switching times. The operating temperature range is -40°C to 100°C, which does not extend to -55°C. Use the TCMT4100 only when the enhanced specifications are acceptable for the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (Renesas PS2801 variants and Vishay TCMT4100) are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). All parts maintain REACH unaffected status and EAR99 export classification.

Q: What is the maximum output current per channel for each part?

A: The PS2801C-4-F3-A (CEL and Renesas variants) and PS2801C-4-V-A support 30mA maximum output current per channel. The Vishay TCMT4100 supports 50mA maximum output current per channel, providing 67% higher current capability.

Q: Can I use the TCMT4100 in applications requiring -55°C operation?

A: No. The TCMT4100 operating temperature range is -40°C to 100°C. If your application requires operation at -55°C, use the Renesas PS2801 variants, which support -55°C to 100°C operation.

Q: What is the isolation voltage difference between the PS2801C-4-F3-A and TCMT4100?

A: The PS2801C-4-F3-A provides 2500Vrms isolation voltage. The TCMT4100 provides 3750Vrms isolation voltage, representing a 50% increase in isolation capability. Both parts meet the 16-SOIC package and surface mount requirements.

Q: Are there any differences in switching performance between the parts?

A: Yes. The Vishay TCMT4100 exhibits faster switching performance: turn-on/turn-off times of 6µs/5µs (versus 10µs/7µs for PS2801C-4-F3-A) and rise/fall times of 3µs/4.7µs (versus 5µs/7µs). This represents approximately 40% faster switching response in the TCMT4100.
