Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MANC3910 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Display Type: 7-Segment (all substitutes must match)
• Common Pin Configuration: Common Anode (all substitutes must match)
• Package / Case: 10-DIP (0.200", 5.08mm) (all substitutes must match)
• Character Height: 0.30" (7.62mm) (all substitutes must match)
• Color: Red (all substitutes must match)

Electrical Operating Parameters:

• Voltage - Forward (Vf): 2V nominal
• Current - Test: 20mA nominal
• Power Dissipation: 70mW maximum

Substitute parts are grouped into two categories based on electrical characteristics:

Group 1 - Direct Electrical Match (Vf = 2V, Current = 20mA):

• HDSP-A211 (Broadcom Limited)
• LSHD-A101 (Lite-On Inc.)

These parts maintain identical electrical specifications to the MANC3910 and require no circuit modifications.

Group 2 - Lower Power Operation (Vf = 1.7V, Current = 5mA):

• HDSP-7511 (Broadcom Limited)
• HDSP-A101 (Broadcom Limited)
• HDSP-A111 (Broadcom Limited)

These parts operate at reduced voltage and current levels, resulting in lower power dissipation. Circuit design modifications may be required to accommodate different electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification Required):

HDSP-A211 (Broadcom Limited) is the primary substitute for MANC3910. This part maintains identical electrical specifications (2V forward voltage, 20mA test current) and identical physical dimensions (0.240" depth). HDSP-A211 is currently in active production status with ROHS3 compliance certification. This substitute requires no changes to existing circuit designs or current-limiting resistor calculations.

LSHD-A101 (Lite-On Inc.) is an alternative direct replacement option. This part operates at 2.1V forward voltage with 20mA test current, maintaining compatibility with the original MANC3910 electrical design. LSHD-A101 offers higher brightness (9mcd) compared to MANC3910 (5.39mcd) and is ROHS3 compliant with active production status.

For Lower Power Applications (Circuit Modification Required):

HDSP-A111 (Broadcom Limited) provides a lower-power alternative with identical physical dimensions to MANC3910 (0.240" depth). This part operates at 1.7V forward voltage with 5mA test current, resulting in 37mW maximum power dissipation compared to 70mW for the original part. Implementation requires recalculation of current-limiting resistor values to accommodate the reduced operating current.

HDSP-A101 (Broadcom Limited) offers similar low-power operation (1.7V, 5mA) but features increased physical depth (0.390" versus 0.240"), which may impact PCB layout compatibility. This part is suitable only if mechanical clearance permits the additional depth.

HDSP-7511 (Broadcom Limited) operates at 1.7V forward voltage with 5mA test current but exhibits the lowest brightness rating (1.05mcd) among all substitutes. The increased physical depth (0.390") may present mechanical constraints. This part is suitable only for applications where reduced brightness is acceptable and mechanical clearance is available.

All substitute parts maintain common anode configuration, 10-DIP package format, 0.30" character height, and red color specification, ensuring functional compatibility with the MANC3910 in terms of display architecture and pinout.

Frequently Asked Questions (FAQ)

Q: Can HDSP-A211 be used as a direct replacement for MANC3910 without any modifications?

A: Yes. HDSP-A211 maintains identical electrical specifications (2V forward voltage, 20mA test current), identical physical dimensions (0.240" depth), and identical package format (10-DIP). No circuit modifications are required.

Q: What is the primary difference between Group 1 and Group 2 substitute parts?

A: Group 1 parts (HDSP-A211, LSHD-A101) operate at 2V forward voltage with 20mA test current, matching the MANC3910 electrical specifications. Group 2 parts (HDSP-7511, HDSP-A101, HDSP-A111) operate at reduced voltage (1.7V) and current (5mA), requiring circuit design modifications to accommodate different electrical characteristics.

Q: Why do some substitute parts have different physical depths?

A: HDSP-A101 and HDSP-7511 feature 0.390" depth compared to MANC3910's 0.240" depth. This difference may affect PCB layout compatibility and mechanical clearance. HDSP-A111 and HDSP-A211 maintain the original 0.240" depth specification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original MANC3910 RoHS status is not specified in available documentation.

Q: What is the brightness difference between MANC3910 and the substitute parts?

A: MANC3910 is rated at 5.39mcd. HDSP-A211 matches this specification. LSHD-A101 provides higher brightness (9mcd). Group 2 parts offer lower brightness: HDSP-A101 and HDSP-A111 at 3.6mcd, and HDSP-7511 at 1.05mcd.

Q: Can HDSP-A111 be used as a direct replacement if my circuit uses current-limiting resistors?

A: HDSP-A111 requires circuit modification. The reduced operating current (5mA versus 20mA) necessitates recalculation of current-limiting resistor values. The forward voltage difference (1.7V versus 2V) also affects resistor calculations. Existing resistor values designed for MANC3910 will not provide correct operating conditions for HDSP-A111.

Q: What is the significance of the wavelength differences listed in the parameter comparison?

A: Wavelength differences (ranging from 635nm to 650nm) represent minor variations in red color perception. All parts are classified as red 7-segment displays. These variations are within the standard red LED spectrum and do not affect functional compatibility or circuit operation.

Q: Is MANC3910 still available for purchase?

A: MANC3910 is classified as obsolete. Active production has been discontinued. All listed substitute parts are currently in active production status with available inventory.
