LTL-4232NH63P Equivalent & Substitute Parts

Part Overview

The LTL-4232NH63P is a 3mm LED Circuit Board Indicator manufactured by Lite-On Inc., featuring a single green clear, tinted lens with a round domed top design. This component operates at 2.1V with a 20mA current rating and delivers 40mcd brightness at a 45° viewing angle. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTL-4232NH63P is determined by the following critical parameters: color (green), wavelength peak (565nm), configuration (single), lens style (round with domed top), mounting type (through hole, right angle), and electrical compatibility (voltage and current ratings within acceptable tolerance).

The substitute parts are grouped into two categories:

Category 1: Lite-On Manufacturer Substitute

• LTL-533-11: Same manufacturer (Lite-On Inc.), matching color, wavelength, configuration, lens style, and mounting type. Differs in lens size (4.80mm vs. 3mm) and current rating (30mA vs. 20mA). Product status is active with improved moisture sensitivity.

Category 2: Dialight Manufacturer Substitutes

• 5501510F, 5501510805F, 5501510804F: Alternative manufacturer (Dialight) with matching green color, lens style (round with domed top), and mounting type (through hole, right angle). These parts feature larger lens sizes (5mm, T-1 3/4) and varying electrical specifications. All are active products with superior moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

LTL-533-11 (Lite-On Inc.) This substitute maintains manufacturer continuity with Lite-On Inc. and preserves the 565nm wavelength specification. The part is active with ROHS3 compliance and superior moisture sensitivity (MSL 1 vs. MSL 2A). The 4.80mm lens size represents a moderate increase from the original 3mm, and the 30mA current rating exceeds the original 20mA specification. This option is suitable for designs where manufacturer consistency and compliance certifications are prioritized.

5501510F (Dialight) This Dialight substitute provides the most complete electrical specification match, with 565nm wavelength confirmation and 2.2V voltage rating closely aligned to the original 2.1V. The 25mA current rating is within acceptable tolerance of the original 20mA. The 5mm lens size represents a larger form factor, and the 110mcd brightness output exceeds the original 40mcd. ROHS3 compliance and MSL 1 rating are confirmed. This option is suitable for designs where electrical performance and compliance documentation are critical.

5501510805F (Dialight) This substitute confirms single green configuration with clear lens type and 5mm lens size. Electrical specifications are not fully documented. ROHS3 compliance and MSL 1 rating are confirmed. This option is suitable for designs where form factor compatibility and compliance are primary concerns.

5501510804F (Dialight) This substitute provides round domed top lens style and 5mm lens size with through hole right angle mounting. Electrical and color specifications are not documented. ROHS3 compliance and MSL 1 rating are confirmed. This option is suitable for designs where mechanical compatibility and compliance are primary concerns.

All substitute parts are active products with improved moisture sensitivity ratings compared to the obsolete LTL-4232NH63P.

Frequently Asked Questions (FAQ)

Q: Can LTL-533-11 be used as a direct replacement for LTL-4232NH63P? A: LTL-533-11 shares the same manufacturer, color, wavelength, configuration, lens style, and mounting type. The primary differences are lens size (4.80mm vs. 3mm) and current rating (30mA vs. 20mA). Compatibility depends on PCB layout constraints and circuit design tolerance for the higher current specification.

Q: What are the key differences between Lite-On and Dialight substitutes? A: LTL-533-11 maintains Lite-On manufacturer continuity. Dialight substitutes (5501510F, 5501510805F, 5501510804F) offer alternative sourcing with larger 5mm lens sizes. All substitutes are active products with MSL 1 moisture sensitivity compared to the obsolete original part's MSL 2A rating.

Q: Which substitute has the most complete electrical specification? A: 5501510F provides the most comprehensive electrical documentation, including confirmed 565nm wavelength, 2.2V voltage rating, 25mA current, and 110mcd brightness output. This part is suitable for designs requiring full electrical performance verification.

Q: Are all substitutes ROHS3 compliant? A: Yes, all four substitute parts (LTL-533-11, 5501510F, 5501510805F, 5501510804F) are ROHS3 compliant. The original LTL-4232NH63P compliance status is not specified.

Q: How do lens size differences affect circuit board layout? A: The original LTL-4232NH63P uses a 3mm T-1 lens. LTL-533-11 increases to 4.80mm diameter, and Dialight substitutes use 5mm T-1 3/4 size. Larger lens sizes require increased PCB clearance and may affect component density in compact layouts.

Q: What is the significance of the MSL rating difference? A: The original part has MSL 2A (4 weeks maximum storage without baking). All substitutes have MSL 1 (unlimited storage), indicating superior moisture resistance and reduced handling constraints during manufacturing and assembly.
