Parameter Comparison

Engineering Selection Recommendations

The ACSA56-41SURKWA-F01 is the manufacturer-recommended substitute for the obsolete ACSA56-41SRWA-F01. Both components are manufactured by Kingbright and maintain identical mechanical compatibility, electrical test current, and maximum power dissipation specifications.

The substitute part offers the following advantages:

Product Status: The ACSA56-41SURKWA-F01 maintains Active product status, ensuring long-term availability and continued manufacturing support compared to the Obsolete status of the original part.

Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for electronic component procurement.

Electrical Characteristics: The substitute part operates at a slightly elevated forward voltage (1.95V versus 1.85V) within acceptable operating margins for common anode 7-segment display applications. The test current remains constant at 20mA.

Optical Performance: The substitute part delivers increased brightness (44mcd versus 26mcd) while maintaining red color specification within the visible spectrum (650nm versus 660nm peak wavelength).

Packaging: Both parts utilize identical 10-SMD, No Lead package configuration with matching physical dimensions, enabling direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the ACSA56-41SURKWA-F01 be used as a direct replacement for the ACSA56-41SRWA-F01 on existing PCBs?

A: Yes. Both components share identical physical dimensions (0.669" H x 0.488" W x 0.148" D), package configuration (10-SMD, No Lead), and pinout for common anode operation. No PCB modifications are required for mechanical or electrical integration.

Q: What is the difference in forward voltage between these two parts?

A: The main part operates at 1.85V typical forward voltage, while the substitute operates at 1.95V typical forward voltage. This 0.10V difference falls within normal operating tolerances for common anode 7-segment display circuits and does not require circuit redesign.

Q: Why does the substitute part have higher brightness (44mcd versus 26mcd)?

A: The substitute part represents a manufacturing improvement from Kingbright, delivering increased luminous intensity while maintaining all other electrical and mechanical specifications. This enhancement provides better display visibility without requiring circuit modifications.

Q: Are there packaging differences between these parts?

A: The main part is supplied in Cut Tape (CT) & Digi-Reel® packaging, while the substitute is supplied in Tape & Reel (TR) packaging. Both packaging formats are standard for SMD components and do not affect component functionality or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ACSA56-41SRWA-F01 and ACSA56-41SURKWA-F01 are ROHS3 compliant and REACH Unaffected, meeting identical regulatory requirements for electronic component procurement and use.

Q: What is the wavelength difference between these displays?

A: The main part operates at 660nm peak wavelength, while the substitute operates at 650nm peak wavelength. Both wavelengths fall within the red spectrum and produce visually equivalent red color appearance in typical display applications.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both components maintain MSL 2A (4 Weeks) moisture sensitivity level, requiring identical storage and handling procedures during manufacturing and assembly processes.
