Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VFJR1104LS-TR are qualified based on strict alignment with the following critical parameters:

Electrical Compatibility: Forward voltage (Vf) of 2V, test current of 20mA, and red color specification ensure direct circuit compatibility without modification to drive circuitry or current-limiting resistor calculations.

Mechanical Compatibility: 2-PLCC package type, surface mount configuration, 3.20mm L x 2.80mm W footprint, and 2.10mm maximum height ensure PCB layout and assembly process compatibility without redesign.

Optical Compatibility: Clear lens transparency, round lens style with flat top, 2.40mm lens diameter, and 120° viewing angle maintain consistent optical performance and mechanical fit within the application envelope.

Regulatory Compliance: ROHS3 compliance and REACH unaffected status ensure substitutes meet the same environmental and regulatory requirements as the primary part.

Wavelength Tolerance: Red LED wavelength specifications (dominant wavelength 620-640nm range, peak wavelength 636-640nm) fall within acceptable red indication standards for this component category.

Substitute parts QBLP670-R and SML-LX2832SIC-TR meet all critical parameters and are classified as parametric equivalents suitable for direct replacement in applications where the VFJR1104LS-TR is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with current manufacturing support and inventory availability. Selection between VFJR1104LS-TR, QBLP670-R, and SML-LX2832SIC-TR is based on supply chain requirements and component availability rather than electrical or mechanical performance differences.

VFJR1104LS-TR (Primary Part): 1190 units in stock. Moisture Sensitivity Level 2A (4 weeks). Established baseline for design reference.

QBLP670-R (Substitute): 4624 units in stock. Moisture Sensitivity Level 3 (168 hours). Higher inventory availability. Millicandela rating 230mcd (higher than primary part). Dominant wavelength 620nm (within red LED specification range).

SML-LX2832SIC-TR (Substitute): 2300 units in stock. Moisture Sensitivity Level 3 (168 hours). Highest millicandela rating at 250mcd. Peak wavelength 636nm (within red LED specification range).

All parts are ROHS3 compliant and REACH unaffected. Substitution does not require circuit redesign, PCB layout modification, or assembly process changes. Forward voltage, test current, package footprint, and mechanical dimensions are identical across all three parts.

Frequently Asked Questions (FAQ)

Q: Can QBLP670-R or SML-LX2832SIC-TR be used as direct replacements for VFJR1104LS-TR without circuit modification?

A: Yes. All three parts share identical forward voltage (2V), test current (20mA), package type (2-PLCC), footprint dimensions (3.20mm L x 2.80mm W), and height (2.10mm maximum). No resistor value changes or circuit redesign is required.

Q: What is the difference in brightness between the three parts?

A: VFJR1104LS-TR delivers 210mcd, QBLP670-R delivers 230mcd, and SML-LX2832SIC-TR delivers 250mcd. All three are suitable for red indication applications with the specified 120° viewing angle and clear lens.

Q: Are there wavelength differences between these parts?

A: VFJR1104LS-TR has dominant wavelength 632nm and peak wavelength 640nm. QBLP670-R has dominant wavelength 620nm. SML-LX2832SIC-TR has peak wavelength 636nm. All wavelengths fall within the red LED specification range and produce visually equivalent red indication.

Q: What is the difference in moisture sensitivity between these parts?

A: VFJR1104LS-TR is rated MSL 2A (4 weeks). QBLP670-R and SML-LX2832SIC-TR are rated MSL 3 (168 hours). MSL 3 requires shorter shelf life management but does not affect electrical or optical performance after assembly.

Q: Can these parts be mixed in the same production batch?

A: Yes. All three parts are mechanically and electrically compatible. They share identical package type, footprint, and electrical specifications. Assembly equipment settings and solder reflow profiles require no adjustment between parts.

Q: Which part should be selected for new designs?

A: Selection is based on supply chain availability and inventory status. QBLP670-R offers highest inventory (4624 units). SML-LX2832SIC-TR offers highest brightness (250mcd). VFJR1104LS-TR is the established baseline. All three are active products with equivalent regulatory compliance.

Q: Are all three parts ROHS3 compliant?

A: Yes. VFJR1104LS-TR, QBLP670-R, and SML-LX2832SIC-TR are all ROHS3 compliant and REACH unaffected. No environmental or regulatory restrictions apply to substitution.
