ACDA56-41SRWA-F01 Equivalent & Substitute Parts

Part Overview

The ACDA56-41SRWA-F01 is a 2-character red 7-segment LED display module manufactured by Kingbright. This component features a 0.56-inch digit height, common anode configuration, and 20-SMD surface-mount package without leads. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain mechanical compatibility, electrical performance within acceptable ranges, and compliance with applicable standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACDA56-41SRWA-F01 are qualified based on the following criteria:

Mechanical Compatibility:

• Identical physical dimensions: 0.669" H x 0.988" W x 0.148" D (17.00mm x 25.10mm x 3.75mm)
• Identical digit height: 0.56" (14.22mm)
• Identical package type: 20-SMD, No Lead
• Common anode configuration maintained

Electrical Compatibility:

• Forward voltage (Vf) within acceptable operating range for common anode circuits
• Current rating compatible with standard LED driver circuits
• Power dissipation within specified maximum of 75mW
• Red color spectrum (wavelength 645nm–660nm)

Compliance & Standards:

• ROHS3 compliance maintained
• MSL rating 2A (4 Weeks) or equivalent
• REACH unaffected status

The two identified substitutes meet these criteria with variations in forward voltage, test current, brightness rating, and product status.

Parameter Comparison

Engineering Selection Recommendations

ACDA56-41SURKWA-F01 (Kingbright - MFR Recommended):

This part is the manufacturer-recommended substitute. It maintains identical mechanical dimensions and package configuration. The forward voltage increases from 1.85V to 1.95V, a 0.10V differential within typical LED circuit tolerance margins. The brightness rating increases to 44mcd compared to 26mcd in the original part. Product status is active with full inventory availability. This substitute is appropriate for direct replacement in existing designs where the higher brightness and slightly elevated forward voltage are acceptable within the circuit design parameters.

XZFMDK14A2 (SunLED - Alternative Substitute):

This part provides mechanical and electrical compatibility with notable differences in test current and brightness. The test current is specified at 10mA compared to 20mA in the original part, resulting in lower power consumption and reduced brightness (14mcd versus 26mcd). Forward voltage matches the original specification at 1.85V. This substitute is suitable for applications where reduced brightness and lower power dissipation are beneficial or where the original brightness specification exceeds circuit requirements. Product status is active.

Both substitutes maintain ROHS3 compliance, identical MSL ratings, and compatible package specifications. Selection between substitutes depends on brightness requirements and power budget constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can ACDA56-41SURKWA-F01 be used as a direct replacement for ACDA56-41SRWA-F01?

A: Yes. Both parts share identical mechanical dimensions, package type, digit height, and common anode configuration. The forward voltage difference of 0.10V (1.85V to 1.95V) is within standard LED circuit design tolerances. The increased brightness (44mcd versus 26mcd) is compatible with common anode driver circuits. Verify that the circuit design accommodates the higher forward voltage specification.

Q: What is the primary difference between ACDA56-41SURKWA-F01 and XZFMDK14A2?

A: The primary differences are test current and brightness rating. ACDA56-41SURKWA-F01 operates at 20mA with 44mcd brightness, while XZFMDK14A2 operates at 10mA with 14mcd brightness. Both maintain identical forward voltage at 1.85V and identical physical dimensions. Selection depends on brightness requirements and power consumption constraints.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical physical dimensions (0.669" H x 0.988" W x 0.148" D), digit height (0.56"), and 20-SMD no-lead package configuration. PCB footprints and mounting requirements are identical.

Q: Does the wavelength difference affect substitution?

A: The wavelength differences (660nm, 650nm, 645nm) represent normal variation within the red LED spectrum. All three parts are classified as red displays. Wavelength differences of this magnitude do not affect functional compatibility in standard applications. Visual color perception differences are minimal across this range.

Q: Why is ACDA56-41SRWA-F01 marked as obsolete?

A: Product status reflects manufacturer discontinuation. ACDA56-41SURKWA-F01 is the active equivalent from the same manufacturer and is recommended for new designs and ongoing production.

Q: Can XZFMDK14A2 be used in high-brightness applications?

A: XZFMDK14A2 provides 14mcd brightness compared to 26mcd in the original part. Applications requiring brightness equal to or greater than the original specification should use ACDA56-41SURKWA-F01 (44mcd) or the original part if available from inventory.

Q: Are there packaging differences between these parts?

A: ACDA56-41SRWA-F01 packaging is not specified in available data. ACDA56-41SURKWA-F01 and XZFMDK14A2 are both supplied in Tape & Reel (TR) format. Confirm packaging requirements for your procurement process.
