Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLMS3100-GS08 is determined by the following critical parameters:

• Package Compatibility: All substitutes must use 2-SMD, J-Lead package with identical mechanical dimensions (3.00mm L x 2.80mm W, 1.85mm max height)
• Optical Characteristics: Red color (630nm dominant wavelength) with clear lens and round flat-top lens style
• Electrical Compatibility: Forward voltage (Vf) and test current must be compatible with circuit design requirements
• Mounting Type: Surface mount configuration required
• Compliance: ROHS3 compliance and MSL 2A rating maintained across all substitutes

The VLMS3100-GS08 serves as the direct manufacturer-recommended equivalent with identical electrical specifications. The VLMS30J1K2-GS08 and VLMS31J1K2-GS08 are parametric equivalents offering alternative forward voltage and test current characteristics while maintaining package, optical, and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

VLMS3100-GS08 is the primary substitute for TLMS3100-GS08. This part maintains identical electrical specifications (2V Vf, 10mA test current) and is the manufacturer-recommended equivalent. The VLMS3100-GS08 is active in production with superior inventory availability (1745 pcs vs. 739 pcs for the obsolete TLMS3100-GS08), ensuring long-term supply continuity.

VLMS30J1K2-GS08 and VLMS31J1K2-GS08 are parametric equivalents suitable for applications where forward voltage and test current variations are acceptable. Both parts are active in production with ROHS3 compliance and MSL 2A rating. Selection between these alternatives depends on circuit design requirements for forward voltage tolerance and current consumption. VLMS31J1K2-GS08 offers the highest inventory level (15433 pcs) and maintains the 10mA test current specification of the original part.

All substitute parts maintain identical mechanical dimensions, package configuration, optical characteristics, and compliance certifications as the TLMS3100-GS08.

Frequently Asked Questions (FAQ)

Q: Can VLMS3100-GS08 be used as a direct replacement for TLMS3100-GS08?

A: Yes. VLMS3100-GS08 is the manufacturer-recommended equivalent with identical electrical specifications, package dimensions, and optical characteristics. No circuit modifications are required.

Q: What are the differences between VLMS30J1K2-GS08 and VLMS31J1K2-GS08?

A: Both are parametric equivalents with different forward voltage specifications. VLMS30J1K2-GS08 operates at 1.8V with 2mA test current and 8mcd brightness. VLMS31J1K2-GS08 operates at 1.9V with 10mA test current and 8mcd brightness. Selection depends on circuit voltage and current requirements.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the 2-SMD, J-Lead package with identical dimensions (3.00mm L x 2.80mm W, 1.85mm max height). No PCB layout modifications are necessary.

Q: Do the substitute parts have the same compliance ratings?

A: Yes. All substitute parts are ROHS3 compliant with MSL 2A (4 Weeks) rating, matching the original TLMS3100-GS08 specifications.

Q: What is the primary reason for substitution?

A: The TLMS3100-GS08 is obsolete. The VLMS3100-GS08 is the active production equivalent, ensuring continued availability and supply chain stability.
