LTL-10233 Equivalent & Substitute Parts

Part Overview

The LTL-10233 is a green diffused through-hole LED manufactured by Lite-On Inc., designed for indication applications with a dominant wavelength of 569nm. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates at a forward voltage of 2.1V with a test current of 10mA and provides a luminous intensity of 12.6mcd with a 60° viewing angle.

The substitute parts HLMP-3507 and HLMP-3962, both manufactured by Broadcom Limited, meet all critical electrical parameters and optical specifications. Both are active products with enhanced compliance certifications and improved availability compared to the obsolete LTL-10233.

Parameter Comparison

Engineering Selection Recommendations

Both HLMP-3507 and HLMP-3962 are suitable substitutes for the obsolete LTL-10233 based on electrical and optical parameter equivalence. The selection between these two Broadcom alternatives depends on luminous intensity requirements:

HLMP-3962 provides 10.6mcd, which closely matches the original LTL-10233 specification of 12.6mcd and is recommended for applications requiring comparable brightness levels.

HLMP-3507 provides 4.2mcd and is suitable for applications where lower luminous intensity is acceptable.

Both substitute parts offer improved compliance status with ROHS3 certification and REACH compliance, along with superior moisture sensitivity ratings (MSL 1 vs. MSL 2A). Physical dimensions differ slightly, with substitute parts measuring 5mm lens diameter and 9.19mm maximum height compared to the original 4.75mm diameter and 7.20mm height. These dimensional differences must be evaluated for mechanical fit within the target application.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3507 and HLMP-3962 be used interchangeably with LTL-10233?

A: Both parts share identical electrical parameters (2.1V forward voltage, 10mA test current) and optical specifications (569nm dominant wavelength, 60° viewing angle, diffused green lens). The primary difference is luminous intensity: HLMP-3962 at 10.6mcd is closer to the original 12.6mcd specification, while HLMP-3507 at 4.2mcd is suitable only for applications tolerant of lower brightness.

Q: What are the mechanical compatibility considerations?

A: The substitute parts use T-1 3/4 (5mm) lens diameter compared to the original 4.75mm diameter. Maximum height increases from 7.20mm to 9.19mm. These dimensional changes require verification against PCB layout, mechanical clearances, and visual appearance requirements in the target application.

Q: Are the substitute parts compliant with current regulations?

A: Yes. Both HLMP-3507 and HLMP-3962 are ROHS3 compliant and REACH unaffected, providing enhanced regulatory compliance compared to the obsolete LTL-10233.

Q: What is the difference in moisture sensitivity between the original and substitute parts?

A: The LTL-10233 has MSL 2A (4 weeks), while both substitute parts have MSL 1 (unlimited). This represents improved moisture tolerance in the substitute parts, reducing handling and storage constraints.

Q: Which substitute part should be selected for new designs?

A: HLMP-3962 is recommended for new designs requiring luminous intensity comparable to the original specification. HLMP-3507 is suitable only when reduced brightness is acceptable for the application.
