MAN492C 7-Segment LED Display Equivalent & Substitute Parts

Part Overview

The MAN492C is a single-character red 7-segment LED display module manufactured by onsemi, housed in a 10-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and production continuity. The display operates at 2V forward voltage with a 20mA test current and features a common anode configuration suitable for standard digital display applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAN492C is determined by the following critical parameters:

• Display Configuration: Single-character 7-segment display with common anode architecture
• Electrical Specifications: Forward voltage range (1.9V to 2.1V), test current of 20mA, and red wavelength emission (635nm to 650nm)
• Package Compatibility: 10-DIP package format with standard 0.300" pin spacing
• Functional Equivalence: All substitute parts maintain identical display functionality and pinout compatibility

The identified substitutes—HDSP-301E and LSHD-A101—meet these core substitution criteria while accommodating minor variations in physical dimensions and optical characteristics within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

HDSP-301E (Broadcom Limited) is the primary substitute for direct replacement applications. This part maintains identical package pin spacing (0.300", 7.62mm) and shares the same 10-DIP footprint as the MAN492C. The forward voltage of 1.9V is within acceptable tolerance of the original 2V specification. The part is currently in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

LSHD-A101 (Lite-On Inc.) serves as an alternative substitute where physical space constraints permit. This part features a more compact 0.200" pin spacing and reduced overall dimensions. The forward voltage of 2.1V and higher millicandela rating (9mcd versus 2.2mcd) make it suitable for applications requiring increased brightness. ROHS3 compliance is confirmed. PCB layout modification is required due to the different pin spacing.

Both substitutes maintain common anode configuration, 7-segment display architecture, and 20mA test current specifications. Selection between HDSP-301E and LSHD-A101 depends on PCB layout constraints and brightness requirements.

Frequently Asked Questions (FAQ)

Q: Can HDSP-301E and LSHD-A101 be used interchangeably with MAN492C?

A: Both parts are functionally equivalent as 7-segment common anode displays with identical electrical test parameters. HDSP-301E requires no PCB modification due to matching pin spacing. LSHD-A101 requires PCB layout changes due to 0.200" pin spacing versus the original 0.300" spacing.

Q: What are the key differences between the substitute parts?

A: HDSP-301E maintains the original 0.300" pin spacing and 0.40" digit size. LSHD-A101 uses 0.200" pin spacing with a smaller 0.30" digit size but offers higher brightness (9mcd). Forward voltage specifications differ slightly: HDSP-301E at 1.9V, LSHD-A101 at 2.1V, both within acceptable tolerance of the original 2V.

Q: Are both substitutes RoHS compliant?

A: Yes. HDSP-301E and LSHD-A101 are both ROHS3 compliant. The original MAN492C RoHS status is not specified in available documentation.

Q: Which substitute is recommended for new designs?

A: Selection depends on design constraints. For direct PCB replacement without layout modification, use HDSP-301E. For space-constrained applications where brightness enhancement is acceptable, use LSHD-A101.

Q: What is the impact of forward voltage differences?

A: The forward voltage variations (1.9V to 2.1V) are within standard engineering tolerance for LED display applications. Current-limiting resistor values may require minor adjustment based on specific circuit design, but functional compatibility is maintained across all three parts.
