FND317C 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The FND317C is a single-character 7-segment LED display module manufactured by onsemi, featuring a 0.36" red display in a 10-DIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The display operates at 2V forward voltage with 20mA test current and is suitable for numeric and alphanumeric display applications requiring common cathode configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FND317C is determined by the following critical parameters:

• Display Type & Configuration: Must be 7-segment, single character, common cathode
• Package Compatibility: Must use 10-DIP (0.200", 5.08mm) package for direct PCB replacement
• Electrical Specifications: Forward voltage (Vf) and test current (20mA) must be compatible with existing circuit design
• Physical Dimensions: Digit size and overall module dimensions affect visual integration and mechanical fit
• Color & Wavelength: Red color family (wavelength 620-660nm range) maintains consistent optical performance

Three substitute parts meet these criteria: HDSP-A153 (Broadcom Limited), LTS-367E (Lite-On Inc.), and SC36-11EWA (Kingbright). Each maintains the 10-DIP package, common cathode configuration, and 20mA test current specification. Variations in forward voltage, brightness, and wavelength are within acceptable ranges for typical display applications.

Parameter Comparison

Engineering Selection Recommendations

HDSP-A153 (Broadcom Limited) - Active product status with ROHS3 compliance. This substitute features a smaller 0.30" digit size compared to the FND317C 0.36" size, which may impact visual integration in existing designs. Forward voltage is 1.8V (0.2V lower), requiring circuit verification for current-limiting resistor adjustment. Brightness is significantly higher at 14mcd versus 2.7mcd. Suitable for applications where reduced physical footprint and increased brightness are acceptable trade-offs.

LTS-367E (Lite-On Inc.) - Active product status with ROHS3 compliance. Maintains identical 0.36" digit size and 2V forward voltage as the FND317C, ensuring direct electrical and mechanical compatibility. Color specification is orange-red (630nm wavelength) rather than pure red, which may produce slight visual color variation. Brightness is lower at 2mcd. Recommended for applications requiring exact size and voltage matching with minimal circuit modification.

SC36-11EWA (Kingbright) - Active product status with ROHS3 compliance and REACH compliance. Maintains 0.36" digit size and 2V forward voltage matching the FND317C. Wavelength (627nm) and brightness (2.1mcd) are closest to original specifications. Packaged in tube format. Recommended as the primary substitute for direct replacement with highest parameter compatibility.

Frequently Asked Questions (FAQ)

Q: Can HDSP-A153 be used as a direct replacement for FND317C? A: HDSP-A153 is electrically compatible but has a smaller 0.30" digit size versus FND317C's 0.36" size. Forward voltage is 1.8V instead of 2V, requiring circuit resistor recalculation. Brightness is significantly higher at 14mcd. Physical and visual integration must be evaluated for your specific application.

Q: What is the primary difference between LTS-367E and SC36-11EWA? A: Both maintain the 0.36" digit size and 2V forward voltage of the FND317C. LTS-367E has orange-red color (630nm) with 2mcd brightness. SC36-11EWA has red color (627nm) with 2.1mcd brightness, providing closer spectral and brightness matching to the original FND317C.

Q: Are all substitute parts in the same 10-DIP package? A: Yes. All three substitute parts use the 10-DIP (0.200", 5.08mm) package, ensuring PCB footprint compatibility with FND317C designs.

Q: Which substitute has the best product status for new designs? A: All three substitutes are classified as active products with current manufacturing status. HDSP-A153, LTS-367E, and SC36-11EWA are all suitable for new production designs. FND317C is obsolete and should not be used for new designs.

Q: Do all substitutes maintain common cathode configuration? A: Yes. All substitute parts maintain common cathode configuration, matching the FND317C electrical interface requirement.

Q: What compliance certifications apply to these parts? A: All substitute parts meet MSL 1 (Unlimited) moisture sensitivity requirements. HDSP-A153, LTS-367E, and SC36-11EWA are ROHS3 compliant. SC36-11EWA additionally carries REACH compliance certification.
