Substitute Part Grouping Explanation

Substitute parts for the VFHG1104LS-TR are qualified based on the following criteria:

Package Compatibility: All substitutes must use 2-PLCC package configuration with identical 3.20mm L x 2.80mm W x 2.10mm H maximum dimensions to ensure PCB footprint compatibility.

Electrical Parameters: Forward voltage (Vf) tolerance range is 2.0V to 2.2V at 20mA test current. Wavelength dominant specification must fall within the green spectrum (561nm to 570nm). Millicandela rating must be 25mcd or greater to maintain brightness performance.

Optical Characteristics: All substitutes feature clear colorless lens with round flat-top lens style and 120° viewing angle, ensuring consistent optical performance in indication applications.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting the same environmental and regulatory requirements as the primary part.

Mounting and Configuration: Surface mount technology with standard configuration across all qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. Selection among these substitutes depends on specific application requirements and supply availability.

VFHG1104LS-TR (Stanley Electric): Primary specification with 2V forward voltage and 561nm wavelength. Optimal for applications with strict voltage budget constraints. Moisture sensitivity level 2A provides superior moisture protection during storage and handling.

AA3528SGS (Kingbright): Forward voltage of 2.2V represents the highest in the group. Suitable for applications where slightly elevated forward voltage is acceptable. Highest inventory availability at 15,219 pieces supports high-volume production requirements. Moisture sensitivity level 3 requires standard handling procedures.

QBLP670-YG1 (QT Brightek): Forward voltage of 2.1V with 28mcd brightness rating provides enhanced luminous intensity compared to the primary part. Wavelength dominant at 570nm remains within green spectrum specification. Appropriate for applications requiring increased brightness output.

SML-LX2832GC-TR (Lumex): Forward voltage of 2.1V with 25mcd brightness matches primary part performance. Peak wavelength at 565nm falls within acceptable green spectrum range. Suitable for general-purpose substitution with equivalent electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can AA3528SGS replace VFHG1104LS-TR in all applications?

A: AA3528SGS is electrically compatible within the 2-PLCC package family. The 0.2V higher forward voltage (2.2V vs 2V) must be evaluated against circuit design margins. Both parts share identical package dimensions, lens specifications, and viewing angle. Compliance certifications are equivalent.

Q: What is the primary difference between QBLP670-YG1 and the other substitutes?

A: QBLP670-YG1 provides 28mcd brightness compared to 25mcd in other parts, representing a 12% increase in luminous intensity. Forward voltage is 2.1V. This part is suitable when enhanced brightness is required within the same package envelope.

Q: Are all substitutes suitable for high-volume production?

A: Inventory levels vary significantly. AA3528SGS offers the highest availability at 15,219 pieces. SML-LX2832GC-TR provides 3,200 pieces, QBLP670-YG1 provides 2,749 pieces, and VFHG1104LS-TR provides 1,096 pieces. Production volume requirements should align with available inventory.

Q: Do moisture sensitivity differences affect component selection?

A: VFHG1104LS-TR carries MSL 2A (4 weeks), providing extended dry storage capability. AA3528SGS, QBLP670-YG1, and SML-LX2832GC-TR carry MSL 3 (168 hours), requiring standard moisture control procedures. Selection depends on supply chain logistics and storage infrastructure.

Q: Is wavelength variation significant among these parts?

A: Wavelength dominant ranges from 561nm to 570nm across the group, all within the green spectrum. Visual color perception remains consistent for indication applications. SML-LX2832GC-TR does not specify dominant wavelength but lists peak wavelength at 565nm, which is within acceptable range.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, all parts share identical 2-PLCC package dimensions (3.20mm L x 2.80mm W x 2.10mm H maximum), ensuring PCB footprint compatibility. Forward voltage differences (2.0V to 2.2V range) require circuit design verification to confirm adequate current limiting and voltage headroom.
