Engineering Selection Recommendations
ACDC56-41SURKWA-F01 (Kingbright - MFR Recommended)
This part is the manufacturer-recommended substitute for the obsolete ACDC56-41SRWA-F01. It maintains identical mechanical specifications and packaging. The forward voltage increases from 1.85V to 1.95V, and brightness increases from 26mcd to 44mcd. Both parts share the same 75mW maximum power dissipation and identical physical footprint. The part is ROHS3 compliant and carries identical moisture sensitivity specifications. Product status is active with current inventory availability. This substitute is suitable for direct replacement in applications where the increased brightness and slightly higher forward voltage are acceptable within circuit design parameters.
XZFMDK14C2 (SunLED - Alternative Substitute)
This part provides mechanical and electrical compatibility with identical physical dimensions and common cathode configuration. The forward voltage matches the original part at 1.85V. The test current is reduced to 10mA with corresponding brightness reduction to 14mcd. The wavelength peak shifts to 645nm within the red spectrum. This part is ROHS3 compliant with identical moisture sensitivity specifications and active product status. Selection of this part is appropriate for applications where lower brightness and reduced current draw are acceptable or beneficial.
Both substitute parts satisfy all mandatory mechanical compatibility requirements, compliance certifications, and moisture sensitivity specifications. Selection between them depends on application-specific requirements for brightness, forward voltage tolerance, and current consumption.
Frequently Asked Questions (FAQ)
Q: Can ACDC56-41SURKWA-F01 be used as a direct replacement for ACDC56-41SRWA-F01?
A: Yes. Both parts share identical mechanical dimensions (0.669" H x 0.988" W x 0.148" D), package type (20-SMD, No Lead), display configuration (2-character, 7-segment, common cathode), and digit size (0.56"). The forward voltage increases from 1.85V to 1.95V, and brightness increases from 26mcd to 44mcd. Circuit design must accommodate these electrical differences.
Q: What are the key differences between ACDC56-41SURKWA-F01 and XZFMDK14C2?
A: Both parts maintain identical mechanical compatibility and physical footprint. ACDC56-41SURKWA-F01 operates at 1.95V with 20mA test current and 44mcd brightness. XZFMDK14C2 operates at 1.85V with 10mA test current and 14mcd brightness. Wavelength peaks differ: 650nm versus 645nm. Selection depends on brightness requirements and current budget.
Q: Are packaging differences between these parts significant?
A: The main part (ACDC56-41SRWA-F01) uses standard packaging. ACDC56-41SURKWA-F01 is supplied in Tape & Reel (TR) format. XZFMDK14C2 is also supplied in Tape & Reel (TR) format. All three parts use identical 20-SMD, No Lead package / case specifications. Tape & Reel packaging is standard for surface mount production environments.
Q: Do all substitute parts meet RoHS and moisture sensitivity requirements?
A: Yes. All three parts are ROHS3 compliant and carry identical Moisture Sensitivity Level (MSL) specifications of 2A (4 Weeks). Compliance certifications are equivalent across all parts.
Q: Why is the original part marked as obsolete?
A: The ACDC56-41SRWA-F01 is classified as obsolete by the manufacturer. ACDC56-41SURKWA-F01 is the active manufacturer-recommended replacement. XZFMDK14C2 provides an alternative from a different manufacturer. Both active alternatives maintain full mechanical and electrical compatibility within specified parameters.
Q: Can circuit design accommodate the brightness differences between substitutes?
A: Yes. Brightness differences (26mcd, 44mcd, and 14mcd) are managed through current-limiting resistor selection in the circuit design. Forward voltage differences (1.85V and 1.95V) are similarly accommodated through resistor value adjustment. Both parameters are within standard design tolerance ranges for 7-segment display applications.
