LS T676-P2S1-1-Z Equivalent & Substitute Parts

Part Overview

The LS T676-P2S1-1-Z is a red LED indication component manufactured by ams-OSRAM USA INC. in the TOPLED® series. This surface-mount 2-PLCC device operates at 2V forward voltage with a dominant wavelength of 633nm and delivers 140 millicandela at 20mA test current. The component is packaged in Tape & Reel format and maintains Active product status with ROHS3 compliance.

Substitute parts become necessary when Tape & Reel packaging is unavailable or when alternative packaging formats such as Cut Tape or Digi-Reel® are required for specific manufacturing processes. Additionally, equivalent devices with enhanced brightness ratings or alternative wavelength specifications may be selected based on application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LS T676-P2S1-1-Z is determined by the following critical parameters:

Primary Substitution Criteria:

• Package / Case type: 2-PLCC (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Lens Size: 2.40mm Dia (mandatory match)
• Color: Red (mandatory match)
• Viewing Angle: 120° (mandatory match)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf): 2V nominal (acceptable range: 1.85V to 2V)
• Current - Test: 20mA (standard test condition)
• Wavelength - Dominant: 633nm to 640nm (acceptable range for red indication)
• Millicandela Rating: 140mcd minimum (brightness tolerance)
• Size / Dimension: 3.20mm L x 2.80mm W (mandatory match)
• Height (Max): 2.10mm (mandatory match)

Packaging Format Variations: Substitutes may differ in packaging format (Tape & Reel, Cut Tape, or Digi-Reel®) without affecting electrical or mechanical compatibility, provided the component count and reel specifications align with manufacturing requirements.

Engineering Selection Recommendations

LS T676-R1S1-1-Z (Primary Substitute)

The LS T676-R1S1-1-Z is the preferred parametric equivalent for the LS T676-P2S1-1-Z. Both components are manufactured by ams-OSRAM USA INC. within the TOPLED® series and maintain identical electrical and mechanical specifications. The primary distinction is packaging format: LS T676-R1S1-1-Z is supplied in Cut Tape and Digi-Reel® formats rather than Tape & Reel. The substitute delivers enhanced brightness at 168mcd compared to the main part's 140mcd while maintaining the same 2V forward voltage and 633nm dominant wavelength. Both components maintain Active product status and ROHS3 compliance with identical Moisture Sensitivity Level (MSL) ratings of 2 (1 Year). This substitute is suitable for direct replacement in applications where packaging format flexibility is acceptable.

AA3528SRS (Secondary Substitute)

The AA3528SRS manufactured by Kingbright is a compatible substitute with notable parameter variations. This component maintains the same 2-PLCC package, 2.40mm lens diameter, 120° viewing angle, and 20mA test current. However, the AA3528SRS operates at a lower forward voltage of 1.85V compared to the main part's 2V, and exhibits a longer dominant wavelength of 640nm versus 633nm. The brightness rating of 150mcd exceeds the main part's 140mcd specification. The AA3528SRS carries Obsolete product status and operates under Moisture Sensitivity Level (MSL) 3 (168 Hours), which is more stringent than the main part's MSL 2 (1 Year). This substitute is suitable only when forward voltage tolerance and extended moisture sensitivity requirements are acceptable to the application design.

Frequently Asked Questions (FAQ)

Q: Can LS T676-R1S1-1-Z be used as a direct replacement for LS T676-P2S1-1-Z?

A: Yes. Both components share identical electrical characteristics (2V forward voltage, 633nm dominant wavelength, 20mA test current) and mechanical specifications (2-PLCC package, 2.40mm lens diameter, 120° viewing angle, 3.20mm L x 2.80mm W dimensions). The difference is packaging format: LS T676-R1S1-1-Z is supplied in Cut Tape and Digi-Reel® rather than Tape & Reel. Both maintain Active product status and ROHS3 compliance.

Q: What are the key differences between LS T676-P2S1-1-Z and AA3528SRS?

A: The components share the same 2-PLCC package, lens size, viewing angle, and test current. Differences include: forward voltage (2V vs. 1.85V), dominant wavelength (633nm vs. 640nm), brightness (140mcd vs. 150mcd), product status (Active vs. Obsolete), and moisture sensitivity (MSL 2 vs. MSL 3). The AA3528SRS is manufactured by Kingbright rather than ams-OSRAM.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel®) is a supply and handling specification only. It does not affect the electrical or optical performance of the LED component itself.

Q: Is the AA3528SRS suitable for new designs?

A: The AA3528SRS carries Obsolete product status. While it remains electrically compatible with the main part, its obsolete classification indicates limited future availability. New designs should prioritize the LS T676-R1S1-1-Z, which maintains Active status.

Q: What is the impact of the 0.15V forward voltage difference between LS T676-P2S1-1-Z and AA3528SRS?

A: The AA3528SRS operates at 1.85V compared to the main part's 2V. This 0.15V difference affects circuit design calculations for current-limiting resistors and power supply requirements. Applications with fixed voltage supplies or tight voltage tolerance specifications must account for this variation.

Q: Are all three components RoHS compliant?

A: Yes. LS T676-P2S1-1-Z, LS T676-R1S1-1-Z, and AA3528SRS all maintain ROHS3 compliance. However, AA3528SRS operates under stricter Moisture Sensitivity Level (MSL 3, 168 Hours) compared to the other two components (MSL 2, 1 Year).

Q: Can LS T676-R1S1-1-Z be used in applications requiring Tape & Reel packaging?

A: LS T676-R1S1-1-Z is supplied in Cut Tape and Digi-Reel® formats. If Tape & Reel packaging is a mandatory requirement for automated assembly processes, this substitute may not be suitable without reel conversion or repackaging services.
