ACDA03-41SRWA-F01 Equivalent & Substitute Parts

Part Overview

The ACDA03-41SRWA-F01 is a 7-segment LED display module manufactured by Kingbright, featuring dual red character display in a compact 20-SMD surface-mount package. This component is classified as obsolete product status, necessitating identification of equivalent substitute parts for ongoing design requirements and production continuity. The display operates at 1.85V forward voltage with 20mA test current and delivers 9.8mcd brightness output at 660nm peak wavelength.

Due to obsolete product status, substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and supply chain requirements.

Engineering Selection Recommendations

ACDA03-41SURKWA-F01 (Kingbright - Recommended Manufacturer Substitute)

This part is the manufacturer-recommended equivalent for ACDA03-41SRWA-F01. Both components share identical mechanical dimensions, package configuration, and base product number (ACDA03). The substitute operates at 1.95V forward voltage (within 0.10V variance) and maintains 20mA test current specification. Brightness output increases to 27mcd, providing enhanced luminous intensity. Product status is Active, ensuring long-term supply availability and manufacturing continuity. RoHS3 compliance and identical moisture sensitivity rating (2A, 4 Weeks) confirm regulatory and handling equivalence. Available in Cut Tape packaging with 1300 units in stock.

LDD-SMHTA304RISITR (Lumex Opto/Components Inc. - Alternative Substitute)

This part provides functional substitution with compatible electrical and mechanical parameters. Forward voltage operates at 2.0V (within 0.15V variance from original specification). Physical depth dimension increases to 0.157" (0.009" tolerance), remaining within acceptable mechanical clearance for standard PCB layouts. Brightness output is lower at 4.5mcd, suitable for applications where reduced luminous intensity is acceptable. Product status is Active with high inventory availability (11881 units). RoHS3 compliance is confirmed. Moisture sensitivity rating is 3 (168 Hours), requiring adjusted storage and handling protocols compared to the original 2A rating. Available in Tape & Reel packaging.

Both substitute parts maintain all fixed electrical and mechanical requirements. Selection between them depends on brightness performance requirements, packaging format preference, and moisture sensitivity handling capabilities.

Frequently Asked Questions (FAQ)

Q: Can ACDA03-41SURKWA-F01 be used as a direct replacement for ACDA03-41SRWA-F01?

A: Yes. Both parts share identical mechanical dimensions (0.394" H × 0.583" W × 0.148" D), package configuration (20-SMD, No Lead), and electrical specifications (2 characters, 7-segment, common anode, red color, 20mA test current). Forward voltage variance is 0.10V (1.85V to 1.95V), which is within acceptable operating tolerance for standard LED display circuits. The substitute is the manufacturer-recommended equivalent.

Q: What are the key differences between the two substitute parts?

A: ACDA03-41SURKWA-F01 (Kingbright) delivers 27mcd brightness at 1.95V with identical physical dimensions. LDD-SMHTA304RISITR (Lumex) operates at 2.0V with 4.5mcd brightness and 0.009" greater depth (0.157" vs 0.148"). Kingbright substitute maintains original moisture sensitivity (2A, 4 Weeks); Lumex substitute has higher moisture sensitivity (3, 168 Hours). Kingbright is available in Cut Tape; Lumex in Tape & Reel.

Q: Is the 0.009" depth difference between ACDA03-41SRWA-F01 and LDD-SMHTA304RISITR significant?

A: The depth variance (0.148" to 0.157") is within standard PCB assembly tolerances for surface-mount components. Verification of available clearance in the specific application is required to confirm mechanical fit, particularly in space-constrained designs.

Q: How do brightness differences affect circuit design?

A: ACDA03-41SURKWA-F01 provides 27mcd (2.75× brighter than original 9.8mcd). LDD-SMHTA304RISITR provides 4.5mcd (0.46× original brightness). Circuit current-limiting resistor values may require adjustment to maintain consistent display brightness. Verify brightness requirements for the specific application before selection.

Q: What is the impact of different moisture sensitivity levels?

A: ACDA03-41SRWA-F01 and ACDA03-41SURKWA-F01 both specify MSL 2A (4 Weeks), allowing 4-week shelf life at uncontrolled humidity. LDD-SMHTA304RISITR specifies MSL 3 (168 Hours), limiting shelf life to 7 days at uncontrolled humidity. Storage and handling protocols must align with the selected component's moisture sensitivity rating.

Q: Are all three parts RoHS3 compliant?

A: Yes. ACDA03-41SRWA-F01, ACDA03-41SURKWA-F01, and LDD-SMHTA304RISITR are all RoHS3 compliant, confirming restricted substance compliance for regulated markets.

Q: Which packaging format should be selected?

A: ACDA03-41SURKWA-F01 is available in Cut Tape (CT) format, suitable for manual assembly and small-volume production. LDD-SMHTA304RISITR is available in Tape & Reel (TR) format, optimized for automated pick-and-place assembly and high-volume production. Select based on manufacturing process requirements.
