Key Parameters

Substitute Part Grouping Explanation

Substitution of the LS T67F.01-U2AB-1-3A4B-20-S is determined by strict alignment of the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 2-PLCC surface-mount package with identical physical dimensions (3.20mm L x 2.80mm W x 2.10mm H maximum).

Optical Specifications: The substitute must be a red LED with comparable wavelength characteristics in the red spectrum range and matching lens configuration (round with flat top, 2.40mm diameter).

Electrical Specifications: Forward voltage must be within acceptable operating range for the application circuit. Test current of 20mA establishes the baseline for performance comparison. Viewing angle of 120° must be maintained.

Mounting and Environmental Compliance: Surface-mount configuration is required. REACH Unaffected and EAR99 ECCN status must be maintained for regulatory compliance.

The ASMM-CR03-BV302 from Broadcom Limited meets all substitution criteria through identical package geometry, compatible red wavelength specification (625nm dominant), comparable forward voltage (2.1V), matching test current (20mA), identical viewing angle (120°), and equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the LS T67F.01-U2AB-1-3A4B-20-S and ASMM-CR03-BV302 are active production components with equivalent regulatory compliance. Selection between these parts is based on availability, supply chain requirements, and application-specific constraints.

The ams-OSRAM part operates at 2.2V forward voltage with a dominant wavelength of 633nm. The Broadcom substitute operates at 2.1V with a dominant wavelength of 625nm. Both wavelengths fall within the red spectrum and both parts maintain identical package geometry, lens configuration, viewing angle, and test current specifications.

The ASMM-CR03-BV302 carries RoHS3 compliance and MSL 3 (168 Hours) moisture sensitivity rating, providing additional environmental qualification data. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Selection should be based on circuit design requirements for forward voltage tolerance, wavelength preference for the specific indication application, and supplier availability. Both parts are suitable for direct substitution in 2-PLCC surface-mount LED indication applications.

Frequently Asked Questions (FAQ)

Q: Can the ASMM-CR03-BV302 be used as a direct replacement for the LS T67F.01-U2AB-1-3A4B-20-S?

A: Yes. Both parts share identical 2-PLCC package geometry, physical dimensions, lens configuration, viewing angle, and test current specifications. The forward voltage differs by 0.1V (2.2V versus 2.1V) and the dominant wavelength differs by 8nm (633nm versus 625nm), both within acceptable tolerance for red LED indication applications. Circuit design must accommodate the forward voltage difference.

Q: What are the critical parameters for substitution?

A: Package type (2-PLCC), physical dimensions (3.20mm L x 2.80mm W x 2.10mm H), lens size (2.40mm diameter), lens style (round with flat top), viewing angle (120°), mounting type (surface mount), and color (red) are the critical parameters that determine substitution compatibility.

Q: Are there differences in wavelength between these parts?

A: Yes. The LS T67F.01-U2AB-1-3A4B-20-S has a dominant wavelength of 633nm with peak at 645nm. The ASMM-CR03-BV302 has a dominant wavelength of 625nm with peak at 630nm. Both are red LEDs suitable for indication applications. Application-specific wavelength requirements should be verified.

Q: What is the forward voltage difference and does it matter?

A: The LS T67F.01-U2AB-1-3A4B-20-S operates at 2.2V typical forward voltage, while the ASMM-CR03-BV302 operates at 2.1V typical forward voltage. This 0.1V difference must be accommodated in circuit design, particularly in current-limiting resistor calculations and power supply margin analysis.

Q: Are both parts in active production?

A: Yes. Both the LS T67F.01-U2AB-1-3A4B-20-S and ASMM-CR03-BV302 are active production components with current inventory availability.

Q: What packaging options are available?

A: The LS T67F.01-U2AB-1-3A4B-20-S is available in standard packaging. The ASMM-CR03-BV302 is available in Tape & Reel (TR) packaging format.

Q: Are there compliance or regulatory differences?

A: Both parts are REACH Unaffected and classified as EAR99 for export control. The ASMM-CR03-BV302 carries additional RoHS3 compliance certification and MSL 3 (168 Hours) moisture sensitivity rating.
