PS2701-1-V-F3-H-A Optoisolator Equivalent & Substitute Parts

Part Overview

The PS2701-1-V-F3-H-A is a high-voltage isolation optoisolator manufactured by CEL, designed for applications requiring galvanic isolation up to 3750Vrms. This component features transistor output configuration with single-channel isolation in a 4-SMD surface mount package. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain identical electrical performance characteristics and isolation ratings while accommodating available packaging and supplier options.

Substitute Part Grouping Explanation

Substitution of the PS2701-1-V-F3-H-A is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Isolation voltage rating: 3750Vrms (non-negotiable)
• Single-channel configuration
• Transistor output topology
• Current transfer ratio range: 50% to 300% @ 5mA
• Maximum output voltage: 40V
• Maximum output current: 80mA per channel
• Vce saturation: 300mV maximum
• Rise/fall time: 3µs and 5µs respectively
• Input type: DC
• Forward voltage: 1.1V typical
• Maximum forward current: 50mA

Mechanical & Environmental Equivalence Criteria:

• Surface mount configuration
• Operating temperature range: -55°C to 100°C
• RoHS3 compliance
• Moisture sensitivity level 1

The PS2701-1-F3-A qualifies as a parametric equivalent based on identical electrical specifications and environmental ratings. Packaging differences (4-SOP vs. 4-SMD Gull Wing) represent the only variation and do not affect functional substitution when PCB layout accommodates the alternative package footprint.

Parameter Comparison

Engineering Selection Recommendations

PS2701-1-F3-A Substitution Basis:

The PS2701-1-F3-A manufactured by Renesas Electronics Corporation is electrically and functionally equivalent to the PS2701-1-V-F3-H-A across all specified parameters. Both components share identical isolation voltage ratings, current transfer ratios, output characteristics, and environmental operating ranges. Both components maintain ROHS3 compliance and moisture sensitivity level 1 certification.

Substitution Constraints:

The primary consideration for substitution is package footprint compatibility. The PS2701-1-F3-A is supplied in 4-SOP package configuration, while the original part uses 4-SMD Gull Wing packaging. PCB layout and land pattern must be evaluated to accommodate the alternative package geometry. Both components are classified as legacy products (discontinued or not for new designs), indicating limited future availability.

Compliance Status:

Both parts maintain identical regulatory compliance: ROHS3 compliant, REACH unaffected, and EAR99 export classification. No compliance barriers exist for substitution.

Frequently Asked Questions (FAQ)

Q: Can PS2701-1-F3-A directly replace PS2701-1-V-F3-H-A without circuit modification?

A: Electrical substitution is direct. The components are parametrically identical across all functional specifications. PCB layout modification is required due to package footprint differences (4-SOP vs. 4-SMD Gull Wing). Circuit schematic connections remain unchanged.

Q: What is the difference between 4-SMD and 4-SOP packaging?

A: Both are surface mount packages with four leads. The 4-SOP (Small Outline Package) and 4-SMD (Surface Mount Device) designations indicate different physical footprints and lead configurations. PCB land patterns must match the specific package type. Consult package datasheets for precise dimensional specifications.

Q: Are there any electrical performance differences between the two parts?

A: No. All electrical parameters are identical: isolation voltage, current transfer ratio, output voltage/current ratings, saturation voltage, and switching times match exactly. Both operate across the same temperature range (-55°C to 100°C).

Q: Why is the original part discontinued?

A: The PS2701-1-V-F3-H-A is discontinued at DiGi Electronics. The substitute PS2701-1-F3-A is marked "Not For New Designs," indicating both are legacy components. For new applications, evaluation of current-generation optoisolator alternatives from active product lines is recommended.

Q: What is the inventory status of the substitute part?

A: PS2701-1-F3-A has 355,200 pieces in stock as new original inventory, providing significantly greater availability than the discontinued original part.

Q: Are both parts RoHS compliant?

A: Yes. Both PS2701-1-V-F3-H-A and PS2701-1-F3-A are ROHS3 compliant with moisture sensitivity level 1 (unlimited shelf life). No environmental or regulatory barriers exist for substitution.

Q: What is the base product number for these components?

A: Both parts share base product number PS2701, confirming they belong to the same product family within the NEPOC series.
