LY P47F-U2AB-36-4A5B-Z Equivalent & Substitute Parts

Part Overview

The LY P47F-U2AB-36-4A5B-Z is an active yellow LED indication component manufactured by ams-OSRAM USA INC. as part of the PointLED® series. This surface mount device operates at a dominant wavelength of 590nm and delivers 1180 millicandela output with a 120° viewing angle. The component is specified for discrete 2-SMD flat lead configuration with a forward voltage of 2.35V at 30mA test current.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across alternative part numbers within the same product family. Substitution becomes necessary when the primary part number experiences supply constraints, inventory limitations, or when design flexibility permits selection from qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LY P47F-U2AB-36-4A5B-Z is determined by strict equivalence across the following critical parameters:

Optical Characteristics: Dominant wavelength (590nm), peak wavelength (597nm), and millicandela rating (1180mcd) must remain constant to preserve color specification and luminous intensity in indication applications.

Mechanical Compatibility: Lens size (1.60mm diameter), lens style (round with flat top), package configuration (2-SMD flat lead), and maximum height (0.88mm) must be identical to ensure PCB layout and assembly compatibility.

Electrical Performance: Forward voltage and test current specifications determine circuit design parameters. Variations in forward voltage (Vf) are permitted within the substitute group when the component maintains the same base product number (LYP47F) and configuration classification.

Compliance & Certification: RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 2, 1 Year) must be maintained across all substitutes.

Mounting & Packaging: Surface mount bottom entry configuration and 2-SMD flat lead package type are non-negotiable for PCB assembly compatibility.

The substitute part LY P47F-U2AB-36-3B5A-Z meets all mechanical, optical, and compliance requirements while operating at a lower forward voltage (2.05V versus 2.35V).

Parameter Comparison

Engineering Selection Recommendations

Both the LY P47F-U2AB-36-4A5B-Z and LY P47F-U2AB-36-3B5A-Z are active products within the PointLED® series manufactured by ams-OSRAM USA INC. Both components maintain full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment.

The primary distinction between these parts is the forward voltage specification: 2.35V for the LY P47F-U2AB-36-4A5B-Z and 2.05V for the LY P47F-U2AB-36-3B5A-Z. This 0.30V difference is a parametric variant within the same product family and does not affect mechanical fit, optical output, or compliance certifications.

Selection between these parts is determined by circuit design requirements. Applications requiring the higher forward voltage specification should use LY P47F-U2AB-36-4A5B-Z. Applications compatible with the lower forward voltage specification may use LY P47F-U2AB-36-3B5A-Z, which offers significantly higher inventory availability (22,779 pieces versus 919 pieces).

Both components are suitable for surface mount assembly with identical mechanical and thermal characteristics. Moisture sensitivity level (MSL 2, 1 Year) applies uniformly across both parts.

Frequently Asked Questions (FAQ)

Q: Can LY P47F-U2AB-36-3B5A-Z be used as a direct replacement for LY P47F-U2AB-36-4A5B-Z?

A: Direct replacement is possible when circuit design accommodates the lower forward voltage (2.05V versus 2.35V). All mechanical, optical, and compliance parameters are identical. The 0.30V difference affects only the voltage drop across the LED in the circuit; current-limiting resistor values may require adjustment to maintain the 30mA test current specification.

Q: Are there differences in optical output between these two parts?

A: No. Both parts deliver identical millicandela rating (1180mcd), dominant wavelength (590nm), peak wavelength (597nm), and viewing angle (120°). Optical performance is equivalent.

Q: What is the significance of the forward voltage difference?

A: Forward voltage (Vf) determines the voltage drop across the LED when operating at the specified test current (30mA). The LY P47F-U2AB-36-4A5B-Z operates at 2.35V while the LY P47F-U2AB-36-3B5A-Z operates at 2.05V. Circuit designs must account for this difference when calculating series resistor values for current limiting. The lower forward voltage of the substitute part results in lower power dissipation in the LED itself.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions (3.40mm L x 1.90mm W), maximum height (0.88mm), lens size (1.60mm diameter), and package configuration (2-SMD flat lead). PCB layout and assembly tooling are interchangeable.

Q: What is the packaging difference between these parts?

A: The main part (LY P47F-U2AB-36-4A5B-Z) is supplied in standard packaging. The substitute part (LY P47F-U2AB-36-3B5A-Z) is supplied in Tape & Reel (TR) packaging. Both are suitable for automated surface mount assembly; tape and reel packaging is standard for high-volume production environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Moisture sensitivity level is MSL 2 (1 Year) for both components.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. If the design specifies 2.35V forward voltage operation, use LY P47F-U2AB-36-4A5B-Z. If the design can accommodate 2.05V forward voltage, LY P47F-U2AB-36-3B5A-Z offers superior inventory availability and is suitable for production deployment.

Q: Are there any thermal or reliability differences?

A: No thermal or reliability parameters are provided in the component specifications. Both parts are manufactured by ams-OSRAM USA INC. within the same PointLED® series and carry identical product status (Active). Thermal and reliability characteristics are equivalent.
