Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2915-1-F3-AX is determined by strict equivalence across the following critical parameters:

Isolation Voltage: 2500Vrms isolation rating is mandatory for all substitutes.

Channel Configuration: Single-channel (1 channel) output topology must be maintained.

Output Stage: Transistor output type is required; no alternative output configurations are acceptable.

Current Transfer Ratio: Minimum 100% and maximum 400% at 1mA input current must be met.

Output Specifications: Maximum output voltage of 40V and output current of 40mA per channel define the load-driving capability.

Timing Characteristics: Turn-on/turn-off times of 40µs and 120µs (typical) and rise/fall times of 5µs and 10µs (typical) establish switching performance.

Package Compatibility: 4-SMD flat lead package with surface mount configuration is required for PCB layout compatibility.

Environmental Compliance: ROHS3 compliance and operating temperature range of -55°C to 100°C must be maintained.

All identified substitutes meet these criteria without deviation.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: PS2915-1-F3-AX (Renesas Electronics Corporation) in Tape & Reel packaging is the direct parametric equivalent to the discontinued CEL part. This substitute maintains identical electrical specifications, package configuration, and compliance certifications. Active product status ensures long-term availability and supply chain stability.

Secondary Substitutes: PS2915-1-V-F3-AX (Renesas) and PS2915-1-V-AX (Renesas) are parametrically equivalent alternatives with identical electrical performance. These parts differ only in packaging format (Tape & Reel versus Strip), which affects procurement and assembly processes but not functional performance.

Compliance Verification: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1 - Unlimited), confirming suitability for equivalent environmental and regulatory requirements.

Supply Chain Consideration: The Renesas Electronics Corporation PS2915-1-F3-AX variant offers the highest inventory availability (7376 Pcs) in Tape & Reel format, supporting high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can PS2915-1-V-AX be used as a direct replacement for PS2915-1-F3-AX?

A: Yes. Both parts are parametrically equivalent across all electrical specifications. The difference is packaging format: PS2915-1-V-AX is supplied in Strip format while PS2915-1-F3-AX is supplied in Tape & Reel. Strip packaging requires manual handling during assembly, whereas Tape & Reel format supports automated pick-and-place equipment. Electrical performance is identical.

Q: What is the difference between PS2915-1-F3-AX and PS2915-1-V-F3-AX?

A: Both parts are manufactured by Renesas Electronics Corporation and are parametrically identical in electrical specifications, isolation voltage, output current, and timing characteristics. Both use Tape & Reel packaging. The designation difference reflects internal Renesas product line variants but does not affect functional equivalence or PCB compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitutes—PS2915-1-F3-AX, PS2915-1-V-AX, and PS2915-1-V-F3-AX from Renesas Electronics Corporation—are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original CEL part.

Q: Does packaging format affect PCB layout or soldering?

A: No. All substitute parts use identical 4-SMD flat lead package configuration and surface mount mounting type. Tape & Reel and Strip packaging formats differ only in how components are supplied and handled during assembly; they do not affect PCB footprint, solder pad layout, or electrical connections.

Q: What is the operating temperature range for all substitutes?

A: All substitute parts operate across the identical temperature range of -55°C to 100°C, ensuring compatibility with applications requiring extended temperature performance.

Q: Can I mix different packaging formats in the same production run?

A: Yes. Since all substitute parts are parametrically equivalent and use identical package geometry, they can be used interchangeably on the same PCB design. However, procurement and assembly logistics may differ based on packaging format (Tape & Reel versus Strip).
