Key Parameters

Substitute Part Grouping Explanation

Substitution of the LS M67F-S2U2-1-1-20-R18-Z is determined by alignment across the following critical parameters:

Functional Compatibility Parameters:

• Color: Red
• Lens Transparency: Clear
• Mounting Type: Surface Mount
• Current - Test: 20mA
• Viewing Angle: 120°

Electrical Compatibility Parameters:

• Voltage - Forward (Vf) (Typ): Within acceptable operating range
• Wavelength - Dominant: Red spectrum (628nm–633nm range)

Regulatory & Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level (MSL): 2 (1 Year)

Physical Compatibility Parameters:

• Mounting Type: Surface Mount (SMD)
• Package Configuration: 2-SMD format

The substitute part KS DELPS1.22-TIVH-68-H3Q4-20-S meets these criteria while offering improved brightness (680mcd versus 467mcd) and a more compact form factor. Both parts are manufactured by ams-OSRAM USA INC. and maintain identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The KS DELPS1.22-TIVH-68-H3Q4-20-S is the manufacturer-recommended substitute for the LS M67F-S2U2-1-1-20-R18-Z. Both components maintain identical compliance certifications under ROHS3 and REACH standards, with matching Moisture Sensitivity Level ratings of 2 (1 Year).

The substitute part operates at a forward voltage of 2.2V compared to 2.05V in the original part, representing a 7.3% increase. This voltage differential is within typical design tolerances for LED indication circuits and does not preclude direct substitution in standard applications.

The substitute part delivers 680 millicandela against the original 467 millicandela, providing 45.6% increased brightness output. This enhanced luminous intensity is compatible with applications requiring improved visibility while maintaining the same 120° viewing angle and 20mA test current.

Physical dimensions differ significantly: the substitute measures 1.40mm L x 0.80mm W with a maximum height of 0.70mm, compared to 2.00mm L x 1.40mm W with 1.40mm height in the original. The substitute employs a Flat Lead configuration versus the J-Lead configuration of the original part. These dimensional and lead-form differences require PCB layout and footprint verification prior to implementation.

The substitute part is classified as Active product status with 39,702 units in stock, ensuring long-term supply availability compared to the Last Time Buy status of the original component.

Frequently Asked Questions (FAQ)

Q: Can the KS DELPS1.22-TIVH-68-H3Q4-20-S directly replace the LS M67F-S2U2-1-1-20-R18-Z without circuit modification?

A: Electrical substitution is feasible within standard LED indication circuit designs. The forward voltage increase from 2.05V to 2.2V requires verification that the driving circuit can accommodate this differential. PCB footprint modification is mandatory due to differences in lead configuration (J-Lead versus Flat Lead) and physical dimensions (2.00mm x 1.40mm versus 1.40mm x 0.80mm).

Q: What are the key differences in physical packaging between these two parts?

A: The original LS M67F-S2U2-1-1-20-R18-Z uses a 2-SMD, J-Lead package measuring 2.00mm L x 1.40mm W with 1.40mm maximum height. The substitute KS DELPS1.22-TIVH-68-H3Q4-20-S uses a 2-SMD, Flat Lead package measuring 1.40mm L x 0.80mm W with 0.70mm maximum height. The substitute is 30% smaller in length, 43% smaller in width, and 50% smaller in height.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 2 (1 Year). No regulatory barriers exist to substitution from a compliance perspective.

Q: How does the brightness difference affect application suitability?

A: The substitute part delivers 680 millicandela compared to 467 millicandela in the original, representing a 45.6% increase in luminous intensity. Both parts maintain the same 120° viewing angle. Applications requiring the original brightness level may require circuit-level current adjustment or optical design modification to accommodate the increased output.

Q: What is the wavelength difference between these parts?

A: The original part has a dominant wavelength of 633nm with peak wavelength of 645nm. The substitute has a dominant wavelength of 628nm with peak wavelength of 643nm. Both wavelengths fall within the red spectrum and are visually indistinguishable in standard indication applications.

Q: Is the substitute part available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) packaging, while the original part packaging format is not specified in the provided data. Verify tape and reel specifications against your assembly equipment requirements.
