PD101SC0SS0F Equivalent & Substitute Parts

Part Overview

The PD101SC0SS0F is a photodiode optical sensor manufactured by Sharp Microelectronics, designed for 820nm wavelength detection in radial, side-view packaging. This component is classified as obsolete, making equivalent or substitute parts necessary for ongoing system support and new design implementations. The photodiode operates with a maximum reverse voltage of 5V and typical dark current of 1nA, suitable for applications requiring near-infrared photodetection.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the PD101SC0SS0F is constrained by the following critical parameters: wavelength specification (820nm), mounting type (Through Hole), package configuration (Radial, Side View), and operating temperature range (-25°C ~ 85°C).

The listed substitute part OP240A is an infrared emitter operating at 890nm with a forward current rating of 50mA and forward voltage of 1.8V. This component differs fundamentally from the PD101SC0SS0F in functional classification (emitter versus photodiode), wavelength (890nm versus 820nm), and electrical characteristics. The OP240A does not meet the photodetection requirements of the original specification and cannot serve as a direct functional equivalent for photodiode applications.

Substitution eligibility requires matching the following parameters:

• Optical function (photodiode detection capability)
• Wavelength range (820nm ± tolerance)
• Mounting configuration (Through Hole, Radial)
• Package orientation (Side View)
• Operating temperature compatibility (-25°C ~ 85°C minimum)

Parameter Comparison

Engineering Selection Recommendations

The OP240A cannot replace the PD101SC0SS0F in applications requiring photodiode detection functionality. The fundamental difference in component type (emitter versus photodiode) and wavelength specification (890nm versus 820nm) makes this substitution unsuitable for photodetection circuits.

For applications currently using the obsolete PD101SC0SS0F, component selection must prioritize:

• Photodiode optical sensors with 820nm wavelength specification
• Through-hole radial packaging with side-view orientation
• Operating temperature range of at least -25°C to 85°C
• Active product status for long-term availability

The OP240A's active product status and ROHS3 compliance are favorable attributes for new designs, but only in applications requiring infrared emission rather than detection.

Frequently Asked Questions (FAQ)

Q: Can OP240A replace PD101SC0SS0F in existing circuits?

A: No. OP240A is an infrared emitter, while PD101SC0SS0F is a photodiode detector. These components serve opposite functions and are not interchangeable.

Q: What is the primary reason these parts are not compatible?

A: The PD101SC0SS0F detects light at 820nm wavelength, while OP240A emits light at 890nm. Additionally, OP240A functions as a light source rather than a light detector, making functional substitution impossible.

Q: Are the package dimensions compatible?

A: Both components use through-hole radial packaging. However, package compatibility alone does not establish functional equivalence. The component type mismatch prevents substitution.

Q: What should be done if PD101SC0SS0F is no longer available?

A: Identify alternative photodiode sensors with matching specifications: 820nm wavelength, through-hole radial side-view packaging, and -25°C to 85°C operating temperature range. Verify responsivity and dark current specifications against application requirements.

Q: Does OP240A's active status make it suitable for new designs using PD101SC0SS0F?

A: OP240A's active status is beneficial for supply chain continuity, but only for applications requiring infrared emission. For photodetection applications, select an active photodiode sensor with equivalent optical and thermal specifications.
