LTL-5233 Equivalent & Substitute Parts

Part Overview

The LTL-5233 is an active green diffused LED indicator manufactured by Lite-On Inc., designed for through-hole mounting applications. This component operates at a forward voltage of 2.1V with a test current of 10mA, delivering 5.6mcd at a dominant wavelength of 569nm. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts becomes necessary when the primary part experiences supply constraints, extended lead times, or when design requirements call for alternative performance characteristics within compatible electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the LTL-5233 baseline.

HLMP-3554 (Broadcom Limited): Operates at identical forward voltage (2.1V) and test current (10mA) as the main part. Brightness output increases marginally to 6.7mcd. Viewing angle narrows to 50° compared to the LTL-5233's 64°. Height tolerance extends to 6.35mm maximum. This substitute provides the closest electrical match with minimal performance deviation.

SSL-LX5063GD (Lumex Opto/Components Inc.): Forward voltage increases to 2.2V with test current elevated to 20mA. Brightness output increases significantly to 30mcd, representing a 5.4x improvement over the main part. Viewing angle widens to 60°. Height remains at 6.00mm. This substitute accommodates higher current applications requiring increased luminous intensity.

WP63GD (Kingbright): Forward voltage matches SSL-LX5063GD at 2.2V with identical 20mA test current. Brightness output reaches 16mcd, providing 2.9x improvement over the main part. Viewing angle matches SSL-LX5063GD at 60°. Height specification aligns at 6.00mm. This substitute balances moderate brightness enhancement with standard electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-3554 replace the LTL-5233 in existing designs without circuit modification?

A: Yes. The HLMP-3554 maintains identical forward voltage (2.1V) and test current (10mA) specifications. The primary design consideration is the reduced viewing angle (50° versus 64°), which may affect visibility in wide-angle applications. Height tolerance increases to 6.35mm; verify PCB clearance if space constraints exist.

Q: What is the primary difference between SSL-LX5063GD and WP63GD?

A: Both parts operate at 2.2V forward voltage and 20mA test current. The SSL-LX5063GD delivers 30mcd brightness, while WP63GD delivers 16mcd. Selection depends on required luminous intensity. Both maintain 60° viewing angle and 6.00mm maximum height.

Q: Do the substitute parts require circuit redesign if the main part operates at 10mA?

A: SSL-LX5063GD and WP63GD operate at 20mA test current, double the LTL-5233 specification. Circuit current-limiting resistors must be recalculated to accommodate the higher operating current and 2.2V forward voltage. HLMP-3554 maintains 10mA operation and requires no current adjustment.

Q: Are all substitute parts through-hole radial mount components?

A: Yes. All three substitute parts (HLMP-3554, SSL-LX5063GD, WP63GD) are through-hole radial mount LEDs with 5mm lens diameter, maintaining mechanical compatibility with LTL-5233 PCB footprints.

Q: What wavelength specifications apply to all parts?

A: All parts maintain peak wavelength at 565nm, confirming green spectrum alignment. The LTL-5233, HLMP-3554, and WP63GD specify dominant wavelength at 569nm, 569nm, and 568nm respectively. SSL-LX5063GD does not specify dominant wavelength but confirms 565nm peak wavelength.
