MANC3110 Red 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The MANC3110 is a single-character red 7-segment LED display manufactured by onsemi, featuring a 0.30" digit size in a 10-DIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The display operates as a common anode configuration with a 2.1V forward voltage and 20mA test current, suitable for numeric and alphanumeric display applications requiring standard brightness levels.

Substitute Part Grouping Explanation

Substitute parts for the MANC3110 are qualified based on the following criteria:

Core Compatibility Requirements:

• Display type: 7-Segment
• Number of characters: 1
• Common pin configuration: Common Anode
• Color: Red
• Digit size: 0.30" (7.62mm)
• Package: 10-DIP (0.200", 5.08mm)
• Moisture Sensitivity Level: 1 (Unlimited)

Electrical Parameter Tolerance:

• Forward voltage (Vf): 1.7V to 2.1V
• Test current: 5mA to 20mA
• Wavelength range: 635nm to 700nm

Physical Dimension Tolerance:

• Height: 0.500" (fixed)
• Width: 0.300" (fixed)
• Depth: 0.240" to 0.390" (minor variation acceptable for PCB mounting clearance)

All substitute parts listed maintain identical pinout compatibility, common anode configuration, and 10-DIP package footprint. Variations in forward voltage, test current, and brightness (millicandela rating) reflect manufacturing improvements and different LED chip technologies while maintaining functional equivalence for standard display applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility): HDSP-A111 and LSHD-A101 are the closest functional equivalents to the MANC3110. Both maintain identical physical dimensions (0.240" depth), common anode configuration, and 10-DIP package footprint. HDSP-A111 is manufactured by Broadcom with ROHS3 compliance and active product status. LSHD-A101 is manufactured by Lite-On Inc. with ROHS3 compliance and active product status. Both operate at reduced test current (5mA for HDSP-A111, 20mA for LSHD-A101) compared to the original specification.

Alternative Substitutes with Minor Depth Variation: HDSP-7511 and HDSP-A101 feature a 0.390" depth compared to the MANC3110's 0.240" depth. This 0.150" increase requires verification of available PCB clearance and component spacing in the target application. Both are Broadcom products with ROHS3 compliance and active status.

High-Brightness Alternative: HDSP-A211 provides the highest brightness rating (5.39mcd) among substitutes while maintaining the original 20mA test current and 2.0V forward voltage specification. Physical dimensions match the MANC3110 exactly. This part is suitable for applications requiring enhanced visibility.

Compliance Consideration: All active substitute parts carry ROHS3 compliance certification, addressing environmental and regulatory requirements for new designs. The original MANC3110 does not specify RoHS status due to its obsolete classification.

Frequently Asked Questions (FAQ)

Q: Can HDSP-7511 or HDSP-A101 be used as direct drop-in replacements despite the increased depth?

A: Electrical and functional compatibility is confirmed. However, the 0.390" depth (versus 0.240" original) requires PCB layout verification. Confirm adequate clearance above the component and verify that adjacent components do not create mechanical interference. If space constraints exist, select HDSP-A111 or LSHD-A101 instead.

Q: What is the impact of lower test current in HDSP-A111 (5mA versus 20mA)?

A: The 5mA test current specification indicates the component operates efficiently at reduced current levels. Circuit design must accommodate this parameter. If the original design requires 20mA operation, select HDSP-A211 or LSHD-A101, both rated for 20mA test current.

Q: Are all substitute parts pin-compatible with the MANC3110?

A: Yes. All listed substitutes maintain identical 10-DIP (0.200", 5.08mm) package configuration and common anode pinout. Direct PCB footprint compatibility is confirmed.

Q: What wavelength differences exist among the substitutes?

A: The MANC3110 operates at 700nm (deep red). Substitutes range from 635nm to 650nm (standard red). This wavelength shift may produce a slightly different color appearance. For applications requiring specific wavelength matching, LSHD-A101 (650nm) provides the closest match to the original specification.

Q: Which substitute offers the best brightness improvement?

A: LSHD-A101 provides 9mcd brightness, representing a 12.9x improvement over the original 0.7mcd rating. HDSP-A211 provides 5.39mcd (7.7x improvement). Both maintain the original 20mA test current and 2.1V/2.0V forward voltage specifications.

Q: Are all substitutes RoHS compliant?

A: All active substitute parts (HDSP-7511, HDSP-A101, HDSP-A111, HDSP-A211, LSHD-A101) carry ROHS3 compliance certification. The original MANC3110 does not specify RoHS status due to obsolete classification.

Q: What is the maximum power dissipation difference among substitutes?

A: Power dissipation ranges from 37mW (HDSP-A101, HDSP-A111) to 105mW (HDSP-A211). Verify thermal design and current limiting resistor values in the target circuit to ensure compatibility with the selected substitute's power rating.
