MAN6910 LED 7-Segment Display - Equivalent & Substitute Parts

Part Overview

The MAN6910 is a dual-character, 0.56" red 7-segment LED display module manufactured by onsemi in 18-DIP packaging. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The display operates at a maximum forward voltage of 2.5V with a test current of 20mA and features common anode configuration suitable for standard LED driver circuits.

Engineering Selection Recommendations

HDSP-521E (Broadcom Limited) - Active product status with ROHS3 compliance and REACH unaffected designation. Forward voltage of 2.05V provides margin below the MAN6910 maximum specification. Highest brightness rating at 4mcd. Tube packaging available.

HDSP-5521 (Broadcom Limited) - Active product in HDSP-552x series with ROHS3 compliance and REACH unaffected status. Forward voltage of 2.1V and brightness of 2.8mcd closely match original specifications. Tube packaging available.

HDSP-K211 (Broadcom Limited) - Active product with ROHS3 compliance and REACH unaffected status. Forward voltage of 2.0V and 2.8mcd brightness align with design requirements. Bulk packaging option available.

LTD-6910HR (Lite-On Inc.) - Active product with ROHS3 compliance. Forward voltage of 2.0V and 2.4mcd brightness are compatible with circuit design. Note: REACH Affected status requires compliance verification for regulated markets. Tube packaging available.

All substitute parts maintain 18-DIP pinout compatibility and operate within the electrical parameters of the original MAN6910 design.

Frequently Asked Questions (FAQ)

Q: Can the MAN6910 be directly replaced with any of these substitute parts?

A: Yes. All substitute parts share identical 18-DIP package pinout, 2-character 7-segment common anode configuration, 0.56" digit size, and 20mA test current. Forward voltage specifications (2.0V to 2.05V) are within acceptable operating ranges for standard LED driver circuits designed for the MAN6910 (2.5V max).

Q: What is the difference in brightness between the MAN6910 and substitute parts?

A: The MAN6910 is rated at 2.2mcd. Substitute parts range from 2.4mcd to 4mcd. The HDSP-521E offers the highest brightness at 4mcd, while HDSP-5521, HDSP-K211, and LTD-6910HR provide comparable or slightly higher brightness than the original.

Q: Are there packaging differences between substitute parts?

A: Yes. HDSP-521E, HDSP-5521, and LTD-6910HR are supplied in Tube packaging. HDSP-K211 is supplied in Bulk packaging. All maintain identical 18-DIP form factor and pinout.

Q: Which substitute part has the best compliance status?

A: HDSP-521E, HDSP-5521, and HDSP-K211 all carry ROHS3 compliance and REACH Unaffected status. LTD-6910HR is ROHS3 compliant but has REACH Affected status, requiring verification for regulated markets.

Q: What is the wavelength difference between the MAN6910 and substitutes?

A: The MAN6910 operates at 635nm peak wavelength. HDSP-521E operates at 640nm (slightly longer wavelength, minimal visual difference). All other substitutes operate at 635nm, matching the original specification.

Q: Can I use these parts interchangeably in existing designs?

A: Yes, for direct circuit substitution. All parts are pin-compatible with identical electrical operating parameters. Forward voltage tolerance (2.0V to 2.05V versus 2.5V max) requires verification that existing current-limiting resistor values accommodate the lower voltage drop without exceeding 20mA test current.
