TLMH3100-GS08 Equivalent & Substitute Parts

Part Overview

The TLMH3100-GS08 is a red 619nm LED indication component in 2-SMD, J-Lead surface mount packaging manufactured by Vishay Semiconductor Opto Division. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The component operates at 2V forward voltage with a 10mA test current and delivers 6mcd luminous intensity with a 120° viewing angle. Substitute parts must maintain compatibility with the 2-PLCC package footprint and electrical operating parameters while accommodating minor variations in wavelength, luminous intensity, and physical dimensions within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLMH3100-GS08 are selected based on the following critical parameters: package compatibility (2-PLCC footprint), forward voltage (2V nominal), test current (10mA), viewing angle (120°), mounting type (surface mount), and compliance certifications (ROHS3, REACH Unaffected). Substitutes are grouped into two categories:

Manufacturer Recommended Substitutes: Parts from the same manufacturer (Vishay Semiconductor Opto Division) that maintain identical or near-identical electrical and mechanical specifications while offering active product status and improved availability.

Parametric Equivalents: Parts from alternative manufacturers that satisfy the core electrical parameters and package requirements, with allowable variations in wavelength, luminous intensity, and physical dimensions within standard engineering tolerances for LED indication applications.

The following parameters determine substitution eligibility:

• Package / Case: 2-PLCC or 2-SMD, J-Lead
• Voltage - Forward (Vf): 2V ±0.2V
• Current - Test: 10mA nominal
• Viewing Angle: 120°
• Mounting Type: Surface Mount
• Compliance: ROHS3 Compliant, REACH Unaffected

Parameter Comparison

Engineering Selection Recommendations

VLMH3100-GS08 (Vishay Semiconductor Opto Division): This part is the primary manufacturer-recommended substitute. It maintains identical package geometry, forward voltage, test current, and viewing angle specifications. The dominant wavelength shifts from 619nm to 618.5nm (amber spectrum), and luminous intensity increases from 6mcd to 10mcd. This part carries active product status with confirmed inventory availability (3650 pcs), ensuring long-term procurement viability. Height increases marginally from 1.75mm to 1.85mm. ROHS3 compliance and REACH unaffected status are maintained. Selection of this part is appropriate when amber color indication is functionally acceptable within the application circuit.

VLMS3100-GS08 (Vishay Semiconductor Opto Division): This parametric equivalent maintains red color indication with a dominant wavelength of 630nm, within the red spectrum range. Forward voltage and test current remain at 2V and 10mA respectively. Luminous intensity is 7.1mcd, closely matching the original 6mcd specification. Package footprint and viewing angle are identical. This part carries active product status with inventory availability (1745 pcs). Height increases to 1.85mm. This selection is optimal when red color indication must be preserved and the original part is unavailable.

HSMS-A100-J00J1 (Broadcom Limited): This alternative manufacturer part maintains red color indication at 626nm dominant wavelength with superior luminous intensity (15mcd). Forward voltage increases to 2.2V and test current doubles to 20mA, requiring circuit design verification to confirm compatibility with existing current-limiting resistor values and power supply specifications. Package designation is 2-PLCC with slightly larger dimensions (3.20mm L x 2.80mm W, 2.10mm height). Viewing angle remains 120°. This part carries active product status with high inventory availability (20168 pcs). Selection requires confirmation that the increased forward voltage and test current do not violate circuit design constraints.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 2A (4 Weeks) moisture sensitivity specifications identical to the original part.

Frequently Asked Questions (FAQ)

Q: Can VLMH3100-GS08 be used as a direct replacement for TLMH3100-GS08?

A: VLMH3100-GS08 is mechanically and electrically compatible with identical package footprint, forward voltage, test current, and viewing angle. The primary difference is color indication: VLMH3100-GS08 is amber (618.5nm) versus the original red (619nm). If the application circuit requires red indication specifically, this part is not suitable. If amber indication is functionally acceptable, this part provides a direct substitute with active product status and improved availability.

Q: What are the implications of using HSMS-A100-J00J1 instead of TLMH3100-GS08?

A: HSMS-A100-J00J1 introduces two circuit-level changes: forward voltage increases from 2V to 2.2V, and test current increases from 10mA to 20mA. These parameters directly affect the current-limiting resistor calculation in the LED circuit. The formula R = (Vsupply - Vf) / If must be recalculated with the new values. Additionally, physical dimensions increase slightly (height from 1.75mm to 2.10mm), which may impact PCB layout clearance in space-constrained designs. Verification of circuit compatibility is required before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. VLMH3100-GS08, VLMS3100-GS08, and HSMS-A100-J00J1 are all ROHS3 compliant and REACH unaffected, matching the compliance status of the original TLMH3100-GS08 part.

Q: What is the difference between VLMH3100-GS08 and VLMS3100-GS08?

A: Both are Vishay Semiconductor Opto Division parts with identical electrical specifications (2V forward voltage, 10mA test current, 120° viewing angle). VLMH3100-GS08 is amber (618.5nm, 10mcd), while VLMS3100-GS08 is red (630nm, 7.1mcd). Selection depends on whether color indication requirements permit amber or require red. Both parts have active product status and comparable availability.

Q: Can package dimensions affect PCB compatibility?

A: Yes. The original TLMH3100-GS08 measures 3.00mm L x 2.80mm W x 1.75mm height. VLMH3100-GS08 and VLMS3100-GS08 maintain identical length and width but increase height to 1.85mm. HSMS-A100-J00J1 increases length to 3.20mm and height to 2.10mm. These dimensional changes may affect PCB layout clearance, particularly in high-density designs or applications with height constraints. Verify PCB footprint compatibility before final part selection.

Q: What is the moisture sensitivity level for all substitute parts?

A: All substitute parts carry MSL 2A (4 Weeks) rating, identical to the original TLMH3100-GS08. This classification requires storage in controlled humidity environments and limits the time between package opening and component soldering to four weeks under standard conditions.
