LED Module SW-27-50-055-01-90 Equivalent & Substitute Parts

Part Overview

The SW-27-50-055-01-90 is an LED Module SelectWHITE™ Linear Light Strip manufactured by Thomas Research Products. This component is classified as an obsolete part status, designed for applications requiring white LED lighting with selectable color temperature options (2200K warm white and 5000K cool white). The module delivers 566 lm to 673 lm depending on color temperature selection at 150 mA test current, with a forward voltage of 28.8 V typical and CRI of 90.

Due to the obsolete status of this component, identifying equivalent substitute parts is necessary to maintain design continuity and ensure supply chain availability for new production runs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SW-27-50-055-01-90 is determined by the following critical parameters:

Configuration Match: Both the main part and substitute must be Linear Light Strip LED modules or engines to maintain form factor and mounting compatibility.

Color Temperature Compatibility: The main part supports dual color temperature operation (2200K and 5000K). Substitute parts must support at least the 5000K cool white specification to maintain functional equivalence for applications requiring this color temperature.

Optical Performance: Luminous flux output, lumens per watt efficiency, and CRI are key performance indicators. Substitute parts should deliver comparable light output and color rendering characteristics.

Electrical Parameters: Forward voltage, test current, and maximum current ratings must be compatible with existing driver circuits and power supply designs.

Physical Dimensions: Linear light strip length and width must be compatible with mechanical mounting and optical design requirements.

Compliance and Certifications: RoHS compliance and MSL rating ensure environmental and handling compatibility.

The substitute part AB-L15D03W504N2 from American Bright Optoelectronics Corporation meets the core substitution criteria for 5000K cool white linear light strip applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: AB-L15D03W504N2 is the designated equivalent for SW-27-50-055-01-90 applications requiring 5000K cool white linear light strip operation.

Compliance Alignment: Both parts maintain RoHS compliance with MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard handling and storage procedures. The substitute part carries ROHS3 Compliant status, representing current regulatory compliance standards.

Active Product Status: The substitute part AB-L15D03W504N2 maintains active product status with 801 units in stock, providing supply chain continuity compared to the obsolete main part.

Electrical Considerations: The substitute part operates at a lower typical forward voltage (24.4 V versus 28.8 V) and lower test current (130 mA versus 150 mA). Driver circuit redesign may be required to accommodate these electrical parameter differences. The substitute part supports higher maximum current (300 mA versus 165 mA), providing operational flexibility.

Optical Performance: The substitute part delivers 535 lm at 130 mA test current with 169 lm/W efficiency, compared to 673 lm at 150 mA with 157 lm/W for the main part at 5000K. The substitute achieves higher lumens per watt efficiency. CRI differs at 80 for the substitute versus 90 for the main part, representing a trade-off in color rendering capability.

Mechanical Compatibility: Dimensional differences exist (145.00 mm L x 18.00 mm W for substitute versus 139.70 mm L x 19.99 mm W for main part). Mechanical mounting and optical design review is required to confirm fit within existing assemblies.

Frequently Asked Questions (FAQ)

Q: Can AB-L15D03W504N2 directly replace SW-27-50-055-01-90 in existing designs?

A: Direct replacement requires engineering review. While both are linear light strip configurations with 5000K color temperature, electrical parameters differ (forward voltage 24.4 V versus 28.8 V, test current 130 mA versus 150 mA). Driver circuit modification may be necessary. Mechanical dimensions also differ slightly, requiring confirmation of mounting compatibility.

Q: What is the primary difference between these two parts?

A: The main part SW-27-50-055-01-90 is an obsolete LED Module with dual color temperature capability (2200K and 5000K) and CRI of 90. The substitute AB-L15D03W504N2 is an active LED Engine with single 5000K color temperature and CRI of 80. The substitute achieves higher lumens per watt efficiency (169 lm/W versus 157 lm/W at 5000K).

Q: Does the substitute part support warm white (2200K) operation?

A: No. The substitute part AB-L15D03W504N2 operates only at 5000K cool white. Applications requiring 2200K warm white operation cannot use this substitute without additional design modifications.

Q: What are the packaging differences?

A: The main part SW-27-50-055-01-90 is packaged in a Box. The substitute part AB-L15D03W504N2 is packaged in a Tray. Handling and storage procedures may differ accordingly.

Q: Are both parts RoHS compliant?

A: Yes. The main part is RoHS Compliant. The substitute part is ROHS3 Compliant, representing current regulatory standards. Both maintain MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the color rendering index difference impact?

A: The main part has CRI of 90, while the substitute has CRI of 80. CRI measures color accuracy relative to natural light. Applications requiring high color fidelity (CRI 90+) may experience perceptible color rendering differences with the substitute part.

Q: Can the substitute part handle higher current than the main part?

A: Yes. The substitute part AB-L15D03W504N2 supports maximum current of 300 mA, compared to 165 mA for the main part. However, operation at test current (130 mA) is recommended for specified performance characteristics.

Q: What viewing angle does the substitute part provide?

A: The viewing angle for substitute part AB-L15D03W504N2 is not specified in available documentation. The main part specifies 120° viewing angle. Optical performance comparison requires additional technical data from the manufacturer.
