L14F1 Phototransistor 880nm TO-206AA Equivalent & Substitute Parts

Part Overview

The L14F1 is an 880nm phototransistor manufactured by onsemi in a TO-206AA (TO-18-3 Metal Can) package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The L14F1 operates across a wide temperature range (-65°C to 125°C) and is suitable for infrared sensing applications requiring top-view optical orientation.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the L14F1 is determined by the following critical parameters:

• Package compatibility: TO-206AA, TO-18-3 Metal Can form factor
• Mounting type: Through Hole
• Optical orientation: Top View
• Operating temperature range: Minimum -65°C to 125°C
• Wavelength sensitivity: 880nm nominal operation
• Dark current specification: Maximum 100 nA
• Voltage rating: Collector-Emitter breakdown minimum 25 V
• Power dissipation: Maximum 300 mW

The substitute parts listed below maintain mechanical and electrical compatibility within these defined parameters. All substitute parts are active products with current manufacturing status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (OP804SL, OP830SL, OP830WSL) are active products with ROHS3 compliance, providing improved regulatory status compared to the obsolete L14F1. Selection among these substitutes depends on specific application requirements:

OP804SL maintains the closest wavelength specification at 890nm and matches the dark current specification of 100 nA. It provides higher voltage rating (30 V) and full temperature range compatibility (-65°C to 125°C).

OP830SL and OP830WSL are functionally equivalent alternatives with identical electrical characteristics. OP830WSL operates across a reduced temperature range (-55°C to 125°C) compared to OP830SL (-65°C to 125°C). Both feature higher dark current (1 µA) and lower voltage rating (15 V) than the L14F1.

All substitute parts maintain the same package form factor, through-hole mounting, and top-view optical orientation as the original L14F1.

Frequently Asked Questions (FAQ)

Q: Can OP804SL directly replace L14F1 in all applications?

A: OP804SL maintains mechanical compatibility (TO-206AA package, through-hole mounting, top-view orientation) and electrical compatibility within the specified parameters. The wavelength difference (890nm vs 880nm) and higher voltage rating (30 V vs 25 V) are within acceptable substitution tolerances for most infrared sensing applications.

Q: What is the difference between OP830SL and OP830WSL?

A: OP830SL and OP830WSL are electrically identical. The primary difference is operating temperature range: OP830SL operates from -65°C to 125°C, while OP830WSL operates from -55°C to 125°C. Selection depends on whether the application requires the extended low-temperature capability.

Q: Why do OP830SL and OP830WSL have higher dark current than L14F1?

A: Dark current specification is a measured parameter provided in the component datasheets. OP830SL and OP830WSL specify 1 µA maximum dark current compared to L14F1's 100 nA. This difference must be evaluated against specific application noise and sensitivity requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. OP804SL, OP830SL, and OP830WSL are all ROHS3 compliant, providing improved environmental and regulatory compliance compared to the obsolete L14F1.

Q: Do all parts use the same package?

A: Yes. L14F1 and all three substitute parts use the TO-206AA (TO-18-3 Metal Can) package with through-hole mounting and top-view optical orientation, ensuring mechanical interchangeability.
