Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLMY3100-GS08 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 2-SMD, J-Lead (mechanical and electrical interface requirement)
• Mounting Type: Surface Mount (assembly process compatibility)
• Wavelength - Dominant: 588nm ±tolerance (color specification for yellow indication)
• Voltage - Forward (Vf): 2.1V ±tolerance (circuit design parameter)
• Viewing Angle: 120° (optical performance specification)
• Lens Style: Round with Flat Top (mechanical fit and optical characteristics)

Secondary Compatibility Criteria:

• Millicandela Rating: Minimum 6mcd (luminous intensity requirement)
• Current - Test: 10mA nominal (standard test condition)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 2A (4 Weeks) (handling and storage requirement)

The identified substitute parts maintain compatibility within the allowed electrical and mechanical parameter ranges for this product category.

Engineering Selection Recommendations

VLMY3100-GS08 (Vishay Semiconductor Opto Division)

This part is the primary substitute for TLMY3100-GS08. It maintains identical package geometry (3.00mm L x 2.80mm W x 1.85mm H), electrical characteristics (2.1V Vf, 10mA test current), and optical specifications (588nm dominant wavelength, 120° viewing angle). The VLMY3100-GS08 is active in production with ROHS3 compliance and 2A MSL rating. The increased millicandela rating (10mcd versus 6mcd) provides enhanced luminous intensity while maintaining full electrical and mechanical compatibility. This part is available in Tape & Reel packaging suitable for automated assembly.

HSMY-A100-J00J1 (Broadcom Limited)

This part serves as an alternative substitute with noted parameter deviations. The dominant wavelength is 585nm (versus 588nm), and the forward voltage is 2.2V (versus 2.1V). The test current is specified at 20mA (versus 10mA), and the lens size is 2.20mm diameter (versus 2.40mm). The package height is 2.10mm (versus 1.85mm). These deviations require circuit-level evaluation for compatibility. The part is active in production with ROHS3 compliance and 2A MSL rating. The higher millicandela rating (12mcd) and amber-yellow color classification indicate different optical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can VLMY3100-GS08 be used as a direct replacement for TLMY3100-GS08?

A: Yes. The VLMY3100-GS08 maintains identical package dimensions, forward voltage, test current, wavelength specifications, and viewing angle. Both parts use the 2-SMD, J-Lead package with 3.00mm L x 2.80mm W x 1.85mm H dimensions. No circuit modifications are required.

Q: What are the key differences between VLMY3100-GS08 and HSMY-A100-J00J1?

A: The VLMY3100-GS08 maintains exact electrical and optical specifications of the original part. The HSMY-A100-J00J1 differs in forward voltage (2.2V versus 2.1V), test current (20mA versus 10mA), dominant wavelength (585nm versus 588nm), lens size (2.20mm versus 2.40mm diameter), and package height (2.10mm versus 1.85mm). These differences require circuit evaluation before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both VLMY3100-GS08 and HSMY-A100-J00J1 are ROHS3 compliant with 2A Moisture Sensitivity Level (4 Weeks), matching the original TLMY3100-GS08 specifications.

Q: What packaging options are available for the substitute parts?

A: VLMY3100-GS08 is supplied in Tape & Reel (TR) format. HSMY-A100-J00J1 is supplied in Cut Tape (CT) & Digi-Reel® format. The original TLMY3100-GS08 was supplied in bulk packaging.

Q: Does the higher millicandela rating of substitute parts affect circuit design?

A: The increased luminous intensity (10mcd for VLMY3100-GS08 and 12mcd for HSMY-A100-J00J1 versus 6mcd for TLMY3100-GS08) may require current limiting resistor adjustment if brightness consistency is critical. Circuit evaluation is necessary to determine if existing resistor values remain appropriate.

Q: Can HSMY-A100-J00J1 be used in applications requiring exact 588nm wavelength specification?

A: No. The HSMY-A100-J00J1 has a dominant wavelength of 585nm, which differs from the 588nm specification of TLMY3100-GS08. Applications with strict wavelength requirements must use VLMY3100-GS08 or verify that the 585nm specification is acceptable for the intended application.
