MSD4910C Equivalent & Substitute Parts

Part Overview

The MSD4910C is a dual-character 7-segment LED display module manufactured by onsemi, featuring red LEDs with common anode configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The display operates at 2V forward voltage with 20mA test current and is housed in a 16-DIP package measuring 0.630" H × 0.795" W × 0.276" D.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MSD4910C are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Display Configuration: 2-character, 7-segment, common anode architecture
• Electrical Specifications: Forward voltage range 2V–2.05V, test current 20mA
• Package Type: 16-DIP (0.500", 12.70mm) form factor
• Physical Envelope: Digit size 0.39"–0.40" (10.00mm–10.16mm)
• Color and Wavelength: Red LEDs, wavelength 627nm–635nm
• Compliance: REACH Unaffected, ECCN EAR99, HTSUS 8541.41.0000

Parts meeting these criteria are electrically and mechanically interchangeable within standard circuit design tolerances.

Parameter Comparison

Engineering Selection Recommendations

HDSP-G01E (Broadcom Limited) is the primary substitute for the MSD4910C. This part maintains identical digit size (0.40"), matching wavelength (635nm), and equivalent electrical characteristics (2.05V forward voltage versus 2V nominal). The HDSP-G01E carries active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. Power dissipation is 65mW, within acceptable margins of the original 70mW specification.

DA04-11EWA (Kingbright) serves as an alternative substitute. While digit size is marginally smaller (0.39" versus 0.40"), this difference remains within standard display module tolerances. The DA04-11EWA exhibits higher luminous intensity (6.4mcd versus 2.2mcd), which may require circuit-level current limiting adjustments. Wavelength differs slightly (627nm versus 635nm), producing a perceptibly warmer red hue. This part is active and ROHS3 compliant.

Both substitutes are mechanically compatible with existing 16-DIP PCB layouts and maintain common anode configuration for direct pin-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DA04-11EWA replace the MSD4910C in existing designs without circuit modification?

A: Mechanical and electrical compatibility is established. However, the DA04-11EWA exhibits 6.4mcd brightness versus the MSD4910C's 2.2mcd. If brightness uniformity is critical, circuit-level current limiting adjustments may be necessary to match the original display intensity.

Q: What is the significance of the wavelength difference between DA04-11EWA (627nm) and HDSP-G01E (635nm)?

A: Both wavelengths fall within the red spectrum. The 627nm wavelength (DA04-11EWA) produces a warmer, orange-tinted red, while 635nm (HDSP-G01E and MSD4910C) produces a standard red appearance. Visual perception differences are noticeable in side-by-side comparison but do not affect functional operation.

Q: Are both substitute parts suitable for new production designs?

A: Yes. Both DA04-11EWA and HDSP-G01E carry active product status and ROHS3 compliance, qualifying them for new designs. The MSD4910C is obsolete and should not be specified for new production.

Q: What is the physical dimension tolerance between these parts?

A: All three parts share identical height (0.630") and width (0.795"). Depth varies slightly: MSD4910C and DA04-11EWA measure 0.276" D, while HDSP-G01E measures 0.272" D. This 0.004" difference is negligible for standard PCB assembly and enclosure design.

Q: Do these parts require different pin configurations or PCB layouts?

A: No. All three parts use identical 16-DIP (0.500", 12.70mm) package with common anode configuration. Direct pin-for-pin substitution is supported without PCB redesign.

Q: What compliance certifications apply to these substitute parts?

A: All three parts are REACH Unaffected and classified as ECCN EAR99. DA04-11EWA and HDSP-G01E carry ROHS3 compliance certification. The MSD4910C RoHS status is not specified in available documentation.
