Key Parameters

Substitute Part Grouping Explanation

Substitution of the H11F2W is determined by the following critical parameters:

• Package Compatibility: Both parts must use 6-DIP (0.400", 10.16mm) through-hole packaging to ensure direct board-level replacement without layout modifications.
• Output Type: MOSFET output configuration must be maintained for circuit functionality.
• Number of Channels: Single-channel isolation requirement must be preserved.
• Isolation Voltage: The substitute must meet or exceed the isolation voltage requirement. The H11F2W specifies 5300Vrms isolation.
• Input Type: DC input type must be consistent.
• Electrical Characteristics: Forward voltage (Vf), maximum forward current (If), and output voltage rating must be compatible with the application circuit.
• Switching Performance: Turn-on and turn-off times affect circuit timing and must be evaluated for application requirements.

The H11F1TVM from Fairchild Semiconductor is identified as a substitute part based on matching package, output type, channel count, input type, and electrical output specifications.

Parameter Comparison

Engineering Selection Recommendations

The H11F1TVM serves as a functional substitute for the H11F2W based on matching package geometry, output configuration, and primary electrical characteristics. Both components share identical maximum output voltage (30V), forward voltage (1.3V), and maximum forward current (60 mA) specifications.

Key differences exist in isolation voltage rating and switching speed. The H11F1TVM provides 4170Vrms isolation compared to the H11F2W's 5300Vrms rating. Applications requiring the full 5300Vrms isolation specification must verify that 4170Vrms meets system safety and regulatory requirements before substitution.

The H11F1TVM exhibits slower switching performance with 45µs turn-on and turn-off times versus the H11F2W's 25µs specification. Applications with timing-critical circuits must evaluate whether this performance difference affects system operation.

The H11F1TVM operates across -40°C to 100°C, compared to the H11F2W's -55°C to 100°C range. Applications requiring operation below -40°C cannot use this substitute.

The H11F1TVM holds active product status, ensuring ongoing availability and supply chain support compared to the obsolete H11F2W.

Frequently Asked Questions (FAQ)

Q: Can the H11F1TVM directly replace the H11F2W without PCB modifications?

A: Yes, both components use identical 6-DIP (0.400", 10.16mm) through-hole packaging, enabling direct pin-for-pin replacement without board layout changes.

Q: What is the primary difference between these optoisolators?

A: The H11F1TVM provides lower isolation voltage (4170Vrms versus 5300Vrms) and slower switching speed (45µs versus 25µs). Electrical output characteristics remain identical.

Q: Is the H11F1TVM suitable for high-voltage isolation applications?

A: The H11F1TVM's 4170Vrms isolation rating is appropriate for applications within this specification. Applications specifically requiring 5300Vrms isolation must confirm that 4170Vrms meets system safety standards before substitution.

Q: How do switching time differences affect circuit performance?

A: The H11F1TVM's 45µs switching time is slower than the H11F2W's 25µs specification. Applications with timing-sensitive circuits must verify that this 20µs difference does not impact system operation or signal integrity.

Q: What is the operating temperature range difference?

A: The H11F2W operates from -55°C to 100°C, while the H11F1TVM operates from -40°C to 100°C. Applications requiring operation below -40°C cannot use the H11F1TVM substitute.

Q: Why is the H11F2W classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The H11F1TVM's active status provides ongoing supply availability for new designs and system support.
