LED Circuit Board Indicator SSA-LXB10GW Equivalent & Substitute Parts

Part Overview

The SSA-LXB10GW is a 10-segment LED circuit board indicator manufactured by Lumex Opto/Components Inc. This through-hole mounted component features a green LED bar configuration with diffused white lens, designed for visual indication applications on printed circuit boards. The part is currently in active production status with 1013 units in stock inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across core parameters including wavelength, voltage rating, mounting type, and configuration. Alternative sources may be required due to supply chain considerations, lead time requirements, or design revision updates.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for LED circuit board indicators is determined by strict alignment of the following core parameters:

Configuration Match: Both parts must maintain the same bar-width DIP configuration (10-segment wide) to ensure PCB footprint compatibility and pin assignment equivalence.

Color & Wavelength: Green LED color specification with peak wavelength within acceptable tolerance range (565nm to 566nm) ensures consistent visual indication characteristics.

Voltage Rating: Identical 2.1V forward voltage rating is required for direct circuit compatibility without redesign of current-limiting resistor networks.

Mounting Type: Through-hole mounting type must be preserved to maintain mechanical fit and soldering process compatibility.

Electrical Performance: Current rating and millicandela output may vary within acceptable ranges provided the substitute part meets minimum brightness requirements for the intended application.

Compliance: RoHS3 compliance and MSL rating of 1 (Unlimited) are mandatory for supply chain and manufacturing process compatibility.

The HDSP-4850 manufactured by Broadcom Limited meets these substitution criteria across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Part - SSA-LXB10GW: Recommended for new designs and applications requiring the specified 8mcd brightness level with 160° viewing angle. This part is in active production with confirmed inventory availability (1013 units in stock). RoHS3 compliance and MSL rating of 1 support standard manufacturing and storage conditions.

Substitute Part - HDSP-4850: Suitable for applications where the lower millicandela rating (1.9mcd) is acceptable for the intended visual indication function. This Broadcom part maintains identical voltage rating, configuration, and mounting type. Current rating of 30mA versus 25mA requires verification that circuit design accommodates the higher current draw. Both parts share active production status and equivalent compliance certifications (RoHS3, MSL 1).

Selection Criteria: Choose the substitute part only when the primary part is unavailable or when the application's brightness requirements are satisfied by the lower 1.9mcd output. Verify circuit current capacity before substitution.

Frequently Asked Questions (FAQ)

Q: Can HDSP-4850 be used as a direct replacement for SSA-LXB10GW on existing PCBs?

A: Yes, both parts share identical through-hole mounting configuration, pin assignment (10-segment DIP), and 2.1V voltage rating. Physical footprint compatibility is maintained. However, the brightness difference (8mcd versus 1.9mcd) must be evaluated for the specific application's visibility requirements.

Q: What is the impact of the 5mA current difference between these parts?

A: The HDSP-4850 operates at 30mA compared to the SSA-LXB10GW at 25mA. Circuit design must confirm that current-limiting resistors and power supply capacity accommodate the higher current draw. Recalculation of resistor values may be necessary to maintain proper LED operation.

Q: Are both parts suitable for high-volume production?

A: Both parts are in active production status with RoHS3 compliance and MSL rating of 1 (Unlimited), supporting standard manufacturing processes and storage conditions. Inventory availability differs: SSA-LXB10GW has 1013 units in stock; HDSP-4850 has 1112 units in stock.

Q: How do the wavelength specifications compare?

A: Peak wavelengths are 565nm (SSA-LXB10GW) and 566nm (HDSP-4850), representing a 1nm difference within acceptable tolerance for green LED indicators. Visual color appearance will be equivalent.

Q: What packaging differences exist between these parts?

A: SSA-LXB10GW packaging is specified as standard through-hole format. HDSP-4850 is supplied in tube packaging. Both maintain identical component form factor and mounting compatibility.
