Substitute Part Grouping Explanation

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

Electrical Equivalence Criteria:

• Voltage - Isolation: 2500Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Current Transfer Ratio range: 100% to 400% @ 1mA (mandatory match)
• Turn On / Turn Off Time: 40µs, 120µs (mandatory match)
• Rise / Fall Time: 5µs, 10µs (mandatory match)
• Input Type: AC, DC (mandatory match)
• Output Type: Transistor (mandatory match)
• Voltage - Output (Max): 40V (mandatory match)
• Current - Output / Channel: 40mA (mandatory match)
• Vce Saturation (Max): 300mV (mandatory match)
• Operating Temperature: -55°C ~ 100°C (mandatory match)

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount (mandatory match)
• Package / Case: 4-SMD, Flat Leads (mandatory match)
• Supplier Device Package: 4-Mini-Flat (mandatory match)

All three substitute parts listed meet these equivalence criteria. Packaging format (Tape & Reel or Strip) represents a logistics variation and does not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Primary Recommendation: PS2915-1-F3-AX

The PS2915-1-F3-AX manufactured by Renesas Electronics Corporation is the direct parametric equivalent to the obsolete PS2915-1-F3-A. This part maintains identical electrical and mechanical specifications while offering active product status. The part is supplied in Tape & Reel format and carries ROHS3 compliance certification with REACH unaffected status, providing regulatory advantages over the original CEL component.

Secondary Recommendation: PS2915-1-V-F3-AX

The PS2915-1-V-F3-AX is functionally equivalent with identical electrical and mechanical parameters. This variant is also manufactured by Renesas Electronics Corporation in active product status with ROHS3 compliance and REACH unaffected designation. Tape & Reel packaging is standard for this part number.

Tertiary Recommendation: PS2915-1-V-AX

The PS2915-1-V-AX provides full parametric equivalence with the original part. Manufactured by Renesas Electronics Corporation, this part is supplied in Strip packaging format rather than Tape & Reel. All electrical specifications, mechanical dimensions, and compliance certifications remain identical to the primary recommendation. Selection of this variant depends on packaging format requirements for assembly operations.

All three substitute parts are manufactured by Renesas Electronics Corporation, an established semiconductor manufacturer with active product lines. The transition from CEL to Renesas components eliminates REACH-affected status and introduces ROHS3 compliance, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can PS2915-1-F3-AX be used as a direct replacement for PS2915-1-F3-A in existing designs?

A: Yes. The PS2915-1-F3-AX is a parametric equivalent with identical electrical and mechanical specifications. All critical parameters including isolation voltage, current transfer ratio, timing characteristics, output voltage and current ratings, and operating temperature range are equivalent. The 4-SMD flat lead package and pin configuration are identical, enabling direct PCB substitution.

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

A: All three parts are parametrically equivalent with identical electrical performance. The differences are in packaging format: PS2915-1-F3-AX and PS2915-1-V-F3-AX are supplied in Tape & Reel format suitable for automated assembly, while PS2915-1-V-AX is supplied in Strip format. Selection depends on assembly line requirements and component handling procedures.

Q: Why is the original PS2915-1-F3-A classified as obsolete?

A: The PS2915-1-F3-A is an obsolete product from CEL. Renesas Electronics Corporation now manufactures equivalent optoisolators in the PS2915 series with active product status, improved compliance certifications, and ongoing manufacturing support.

Q: Are there any compliance differences between the original part and the substitutes?

A: Yes. The original PS2915-1-F3-A carries REACH Affected status, while all three Renesas substitutes are REACH Unaffected. Additionally, the Renesas parts carry ROHS3 compliance certification, which is not specified for the original CEL component. These certifications support compliance with modern regulatory requirements in electronics manufacturing.

Q: What is the moisture sensitivity level for these optoisolators?

A: All parts including the original PS2915-1-F3-A and the three substitute parts carry MSL 1 (Unlimited) rating. This indicates minimal moisture sensitivity and no special storage or handling requirements related to moisture exposure.

Q: Can these parts be used in both AC and DC input applications?

A: Yes. All parts in this comparison support both AC and DC input types, enabling use in diverse circuit configurations including isolated gate drivers, signal isolation, and power supply feedback circuits.

Q: What is the maximum output current for these optoisolators?

A: The maximum output current per channel is 40mA for all parts in this comparison. Circuit design must account for this current limitation when selecting load resistances and output circuit configurations.

Q: Are the electrical timing characteristics identical across all substitute parts?

A: Yes. Turn on/off times (40µs, 120µs typical) and rise/fall times (5µs, 10µs typical) are identical across the original part and all three substitutes, ensuring equivalent performance in timing-sensitive applications.
