LDS-A5642RI Equivalent & Substitute Parts

Part Overview

The LDS-A5642RI is a green 7-segment LED display module manufactured by Lumex Opto/Components Inc. This single-character display operates as a common anode configuration with a 0.56-inch digit height and 10-DIP package format. The component is currently in active product status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical and mechanical tolerances of alternative manufacturers' offerings. Equivalent parts must maintain compatibility with the 10-DIP package footprint and common anode configuration while operating within specified voltage and current parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LDS-A5642RI is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 10-DIP (0.600", 15.24mm) package format to ensure direct PCB footprint compatibility.

Electrical Configuration: All parts must operate as common anode 7-segment displays with single-character output.

Display Characteristics: Digit height of 0.56 inches (14.22mm) is the primary size specification. Minor variations in overall housing dimensions are acceptable provided the digit height remains within the specified range.

Electrical Operating Range: Forward voltage (Vf) must fall within 2.0V to 2.2V typical range. Test current of 10mA to 20mA is acceptable. Maximum power dissipation must not exceed 105mW.

Color and Wavelength: Green color with peak wavelength between 565nm and 566nm.

Compliance Requirements: All parts must maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

The following substitute parts meet these criteria: HDSP-5601, HDSP-5601-GH000, SA52-11GWA, and XDUG14A.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

HDSP-5601 (Broadcom Limited) is the preferred substitute for the LDS-A5642RI. Both components share identical package specifications, digit height, and test current parameters. The HDSP-5601 operates at 2.1V typical forward voltage compared to 2.2V for the LDS-A5642RI, representing a 0.1V reduction within acceptable design margins. Both maintain 105mW maximum power dissipation and ROHS3 compliance. The HDSP-5601 is currently in active product status with 1960 units in stock.

XDUG14A (SunLED) provides an alternative with matching digit height and 10-DIP package configuration. This component operates at 2.0V typical forward voltage with 10mA test current. The XDUG14A exhibits higher brightness at 11mcd compared to the LDS-A5642RI at 3.9mcd, with reduced power dissipation of 62.5mW. The component is in active product status with 1071 units in stock.

SA52-11GWA (Kingbright) is compatible with the LDS-A5642RI in package format and common anode configuration. This component features a 0.52-inch digit height (13.21mm) compared to the 0.56-inch specification of the LDS-A5642RI, representing a 7.6% reduction in display size. The SA52-11GWA operates at 2.2V forward voltage matching the LDS-A5642RI but requires 20mA test current (double the LDS-A5642RI specification) with reduced power dissipation of 62.5mW. The component is in active product status with 1878 units in stock.

Secondary Substitute (Obsolete Status):

HDSP-5601-GH000 (Broadcom Limited) is electrically and mechanically equivalent to the HDSP-5601 but carries obsolete product status. This component should be selected only when supply of active alternatives is unavailable. The HDSP-5601-GH000 maintains identical electrical parameters and ROHS3 compliance with 892 units currently in stock.

Selection Criteria Summary:

For direct replacement requiring no design modification, select HDSP-5601 or XDUG14A. For applications where reduced display size is acceptable, SA52-11GWA is suitable with consideration for increased current draw. Avoid HDSP-5601-GH000 unless active alternatives are exhausted due to obsolete product status.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-5601 directly replace the LDS-A5642RI without circuit modification?

A: Yes. The HDSP-5601 maintains identical 10-DIP package footprint, common anode configuration, and test current of 10mA. The 0.1V reduction in forward voltage (2.1V vs. 2.2V) falls within standard design tolerances for LED display circuits and does not require circuit modification.

Q: What is the primary difference between HDSP-5601 and HDSP-5601-GH000?

A: Both components are electrically and mechanically identical. The distinction is product status: HDSP-5601 is active, while HDSP-5601-GH000 is obsolete. Select HDSP-5601 for new designs and ongoing production.

Q: Is SA52-11GWA suitable as a substitute despite the smaller digit height?

A: SA52-11GWA is mechanically compatible with the 10-DIP package and electrically compatible with common anode operation. However, the 0.52-inch digit height is 7.6% smaller than the LDS-A5642RI specification of 0.56 inches. This substitution is acceptable only in applications where reduced display size does not impact readability or user interface requirements. Additionally, SA52-11GWA requires 20mA test current compared to 10mA for the LDS-A5642RI, necessitating circuit current capacity verification.

Q: Why does XDUG14A have lower power dissipation despite higher brightness?

A: XDUG14A operates at 2.0V forward voltage with 10mA test current, resulting in 20mW typical power dissipation per segment. The LDS-A5642RI at 2.2V and 10mA produces 22mW per segment. The higher brightness rating (11mcd vs. 3.9mcd) reflects superior LED efficiency in the SunLED design rather than increased power consumption.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (HDSP-5601, HDSP-5601-GH000, SA52-11GWA, and XDUG14A) maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), matching the LDS-A5642RI compliance profile.

Q: What is the wavelength difference between substitute parts?

A: The LDS-A5642RI, SA52-11GWA, and XDUG14A all specify 565nm peak wavelength. The Broadcom HDSP-5601 and HDSP-5601-GH000 specify 566nm peak wavelength. This 1nm difference is within standard green LED manufacturing tolerances and produces no perceptible color variation in typical applications.

Q: Can multiple substitute parts be used interchangeably in the same circuit?

A: HDSP-5601 and XDUG14A are directly interchangeable with the LDS-A5642RI without circuit modification. SA52-11GWA requires current capacity verification due to 20mA test current specification. HDSP-5601-GH000 is electrically interchangeable with HDSP-5601 but should not be selected for new designs due to obsolete status.

Q: What inventory considerations apply to substitute selection?

A: Current stock levels are: LDS-A5642RI (933 units), HDSP-5601 (1960 units), HDSP-5601-GH000 (892 units), SA52-11GWA (1878 units), and XDUG14A (1071 units). All parts are available in sufficient quantity for production requirements.
