MAN412C 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The MAN412C is a single-character red 7-segment LED display manufactured by onsemi, featuring a common anode configuration 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 2.1V forward voltage with a 20mA test current and provides 0.7mcd brightness output. Identifying compatible alternatives ensures design flexibility while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAN412C must satisfy the following criteria:

• Display Configuration: Single-character 7-segment display with common anode configuration
• Package Compatibility: 10-DIP (0.300", 7.62mm) package for direct PCB mounting
• Electrical Parameters: Forward voltage range 1.9V–2.1V and test current of 20mA
• Color and Wavelength: Red LED with wavelength in the 635nm–697nm range
• Physical Dimensions: Digit size approximately 0.39"–0.40" (10.00mm–10.16mm)
• Mechanical Fit: Overall dimensions compatible with 10-DIP footprint (depth 0.276" / 7.00mm)

The two identified substitutes meet these criteria while offering active product status and improved availability compared to the obsolete MAN412C.

Parameter Comparison

Engineering Selection Recommendations

HDSP-301E (Broadcom Limited) is an active product with higher brightness output (1.8mcd versus 0.7mcd) and lower forward voltage (1.9V). This substitute provides improved performance characteristics and superior long-term availability. The slightly higher power dissipation (105mW) must be evaluated against circuit design constraints. RoHS3 compliance ensures regulatory alignment for new designs.

LTS-4801P (Lite-On Inc.) matches the MAN412C electrical specifications precisely, with identical forward voltage (2.1V) and power dissipation (40mW). This substitute maintains the closest electrical behavior to the original part while offering active product status and RoHS3 compliance. Inventory availability (888 units) supports production requirements.

Both substitutes are pin-compatible with the MAN412C in 10-DIP configuration and maintain common anode functionality. Selection between them depends on brightness requirements and power budget constraints in the target application.

Frequently Asked Questions (FAQ)

Q: Can HDSP-301E replace MAN412C directly without circuit modification?

A: HDSP-301E is pin-compatible and functionally equivalent in 10-DIP configuration. The lower forward voltage (1.9V versus 2.1V) may require current-limiting resistor adjustment to maintain consistent brightness levels. Verify circuit design parameters before substitution.

Q: What is the difference in brightness between these displays?

A: MAN412C provides 0.7mcd, LTS-4801P provides 0.8mcd, and HDSP-301E provides 1.8mcd. The HDSP-301E offers significantly higher brightness output. Application visibility requirements determine whether this difference is acceptable or beneficial.

Q: Are all three parts RoHS compliant?

A: MAN412C carries no RoHS designation due to obsolete status. HDSP-301E and LTS-4801P are both RoHS3 compliant, meeting current environmental and regulatory standards for new product designs.

Q: Do these displays have identical mechanical dimensions?

A: All three parts use 10-DIP (0.300", 7.62mm) packaging with 0.276" depth. Digit sizes vary slightly: MAN412C and LTS-4801P at 0.39" (10.00mm), HDSP-301E at 0.40" (10.16mm). These variations are within standard display tolerance ranges and do not affect PCB footprint compatibility.

Q: What is the wavelength difference between MAN412C and HDSP-301E?

A: MAN412C emits at 697nm (standard red), while HDSP-301E emits at 635nm (pure red). The wavelength difference may produce slightly different color perception under identical viewing conditions. Application-specific color matching requirements should guide selection.
