Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAN3R40 are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Display type: 7-segment, single character
• Digit height: 0.30" (7.62mm)
• Package: 10-DIP (0.200", 5.08mm)
• Common pin configuration: Common cathode
• Color: Red
• Physical height and width: 0.500" H x 0.300" W

Electrical Parameter Ranges:

• Forward voltage (Vf): 1.7V to 2.0V (MAN3R40 operates at 2.05V)
• Test current: 5mA to 20mA (MAN3R40 operates at 10mA)
• Peak wavelength: 635nm to 645nm (MAN3R40 at 639nm)

Acceptable Variations:

• Depth dimension: 0.240" to 0.390" (accommodates different internal construction)
• Brightness rating: 1mcd to 14mcd (higher brightness acceptable for direct replacement)
• Power dissipation: Up to 105mW (higher dissipation acceptable)

All substitute parts listed are manufactured by Broadcom Limited and carry active product status with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement Priority:

HDSP-A113 and HDSP-7513 provide the closest electrical match to the MAN3R40 with 1.7V forward voltage and 5mA test current, resulting in the lowest power dissipation (37mW and 52mW respectively). Both are active products with ROHS3 compliance. HDSP-A113 is available in bulk packaging, while HDSP-7513 is supplied in tube packaging.

Higher Current Applications:

HDSP-A153, HDSP-7503, and HDSP-A213 operate at 20mA test current with forward voltages between 1.8V and 2.0V. These parts deliver increased brightness (5.39mcd to 14mcd) and are suitable for applications requiring higher luminous intensity. All three are active products with ROHS3 compliance.

Low Power Variant:

HDSP-A103 matches the electrical characteristics of HDSP-A113 (1.7V, 5mA) with identical power dissipation (37mW) but offers 3.6mcd brightness. This part is available in tube packaging and provides an alternative to HDSP-A113 for low-power designs.

All substitute parts maintain common cathode configuration, 10-DIP package compatibility, and 0.30" digit height. All substitute manufacturers (Broadcom Limited) maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance for new designs.

Frequently Asked Questions (FAQ)

Q: Can HDSP-A153 directly replace MAN3R40 in existing designs?

A: HDSP-A153 is electrically compatible as a substitute. It maintains the same 10-DIP common cathode package, 0.30" digit height, and red color. However, HDSP-A153 operates at 1.8V forward voltage and 20mA test current compared to MAN3R40's 2.05V and 10mA. Circuit current-limiting resistors must be recalculated to accommodate the 20mA test current specification. HDSP-A153 delivers 14mcd brightness versus MAN3R40's 1mcd, resulting in a brighter display.

Q: What is the difference between HDSP-7513 and HDSP-A113?

A: Both parts share identical electrical specifications: 1.7V forward voltage, 5mA test current, 37mW maximum power dissipation, and 3.6mcd brightness. The primary difference is physical depth: HDSP-7513 measures 0.390" depth while HDSP-A113 measures 0.240" depth. HDSP-A113 also differs in wavelength (645nm versus 635nm) and packaging format (bulk versus tube). Select based on available PCB space and packaging requirements.

Q: Are all substitute parts RoHS compliant?

A: All Broadcom substitute parts listed (HDSP-7503, HDSP-7513, HDSP-A103, HDSP-A113, HDSP-A153, HDSP-A213) are ROHS3 compliant. The original MAN3R40 does not specify RoHS status. For new designs requiring RoHS compliance, any of the listed Broadcom substitutes satisfy this requirement.

Q: Which substitute offers the lowest power consumption?

A: HDSP-A103 and HDSP-A113 both deliver the lowest power dissipation at 37mW maximum, operating at 1.7V forward voltage and 5mA test current. Both parts are suitable for battery-powered or low-power applications. HDSP-A113 is available in bulk packaging while HDSP-A103 is supplied in tube packaging.

Q: Can I use HDSP-A153 in a circuit designed for MAN3R40 without modification?

A: Direct substitution requires circuit modification. HDSP-A153 operates at 20mA test current versus MAN3R40's 10mA, necessitating recalculation of current-limiting resistor values. The forward voltage difference (1.8V versus 2.05V) also affects resistor sizing. Additionally, HDSP-A153's 14mcd brightness is significantly higher than MAN3R40's 1mcd, which may require optical considerations in the application.

Q: What packaging options are available for substitutes?

A: HDSP-7503 and HDSP-7513 are supplied in tube packaging. HDSP-A103 is supplied in tube packaging. HDSP-A113, HDSP-A153, and HDSP-A213 are supplied in bulk packaging. Select packaging based on production volume and handling requirements.
