ACPSA04-41SRWA Equivalent & Substitute Parts

Part Overview

The ACPSA04-41SRWA is a 14-segment alphanumeric LED display module manufactured by Kingbright, featuring a single red character with 0.40" digit height in a 16-SMD surface-mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The display operates as a common anode configuration with typical forward voltage of 1.85V and test current of 20mA, suitable for alphanumeric information display in industrial and consumer electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACPSA04-41SRWA are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Critical Matching Parameters:

• Display Type: 14-Segment, Alphanumeric
• Number of Characters: 1
• Common Pin Configuration: Common Anode
• Package / Case: 16-SMD, No Lead
• Color: Red
• Digit/Alpha Size: 0.40" (10.16mm)

Allowable Variation Parameters:

• Voltage - Forward (Vf): Within operating range of host circuit design
• Current - Test: Within circuit current sourcing capability
• Millicandela Rating: Brightness variation acceptable if circuit design permits
• Wavelength - Peak: Red spectrum variation (645nm to 660nm range)
• Physical Dimensions: Identical footprint required for PCB compatibility

Two substitute parts meet these criteria with documented compatibility to the main part number.

Engineering Selection Recommendations

ACPSA04-41SURKWA (Kingbright - MFR Recommended Substitute)

This part is the primary recommended substitute for the obsolete ACPSA04-41SRWA. Both components share identical physical dimensions (13.00mm x 9.30mm x 3.75mm), package configuration (16-SMD, No Lead), and electrical specifications within acceptable operating ranges. The ACPSA04-41SURKWA is currently in active production status with higher inventory availability (1537 pcs). The forward voltage differential of 0.10V (1.95V vs. 1.85V) and increased brightness rating (36mcd vs. 15mcd) are within standard circuit design tolerances for common anode LED display applications. Both parts maintain identical RoHS3 compliance and MSL ratings. This substitute is suitable for direct PCB replacement without design modification.

XZFAMDK10A (SunLED - Similar Substitute)

This part provides functional equivalence as a 14-segment, single-character, common anode red LED display in 16-SMD package. However, the XZFAMDK10A exhibits a critical dimensional difference: the height is 0.748" (19.00mm) compared to 0.512" (13.00mm) for the main part. This 6mm height increase requires PCB layout verification and may not be suitable for space-constrained applications. The test current specification is reduced to 10mA (versus 20mA), and brightness is lower at 8mcd. The wavelength peak of 645nm falls within acceptable red spectrum variation. This substitute is applicable only when PCB footprint accommodation for increased height is confirmed.

Frequently Asked Questions (FAQ)

Q: Can ACPSA04-41SURKWA be used as a direct replacement for ACPSA04-41SRWA without circuit modification?

A: Yes. Both parts share identical physical dimensions, package configuration, and electrical operating parameters within standard design tolerances. The forward voltage difference of 0.10V is within typical circuit design margins for common anode LED display applications. No circuit redesign is required.

Q: What is the primary difference between ACPSA04-41SURKWA and XZFAMDK10A?

A: The XZFAMDK10A has a significantly larger height dimension (0.748" vs. 0.512"), making it unsuitable for applications with strict vertical space constraints. Additionally, the XZFAMDK10A operates at 10mA test current versus 20mA, resulting in lower brightness output (8mcd vs. 36mcd for the Kingbright substitute).

Q: Why is ACPSA04-41SRWA listed as obsolete?

A: The ACPSA04-41SRWA is classified as obsolete by the manufacturer. The ACPSA04-41SURKWA is the active production equivalent, offering improved specifications and continued manufacturing support.

Q: Are all three parts RoHS3 compliant?

A: Yes. ACPSA04-41SRWA, ACPSA04-41SURKWA, and XZFAMDK10A are all ROHS3 compliant with identical MSL ratings of 2A (4 Weeks).

Q: What packaging formats are available for these parts?

A: ACPSA04-41SRWA is supplied in standard packaging (not specified). ACPSA04-41SURKWA is available in Cut Tape (CT) format. XZFAMDK10A is supplied in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly requirements.

Q: Can XZFAMDK10A be used in applications requiring 20mA operation?

A: The XZFAMDK10A is specified for 10mA test current. Operating at 20mA would exceed the component's rated specifications and is not recommended.

Q: What wavelength variations exist among these three parts?

A: Wavelength peaks range from 645nm (XZFAMDK10A) to 660nm (ACPSA04-41SRWA), representing standard red spectrum variation. All three parts are classified as red color displays and are visually compatible within typical human perception thresholds.
