TAN1111C-TR Equivalent & Substitute Parts Reference

Part Overview

The TAN1111C-TR is an Infrared (IR) Emitter operating at 940nm wavelength, manufactured by Stanley Electric Co. This component is classified as obsolete, which necessitates identification of active equivalent parts for continued system design and procurement. The TAN1111C-TR is a surface-mount device in 0603 (1608 Metric) package format, designed for LED indication applications requiring infrared emission at 50mA maximum forward current and 1.22V typical forward voltage.

Due to its obsolete status, sourcing new inventory from original manufacturing channels is no longer available through standard distribution. Identifying functionally equivalent active parts ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TAN1111C-TR is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Wavelength: 940nm (exact match required)
• Forward Voltage (Vf): 1.22V typical (exact match required)
• Maximum Forward Current (If): 50mA (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Viewing Angle: 145° (exact match required)

Secondary Compatibility Factors:

• Operating temperature range must encompass or exceed the original specification
• Moisture sensitivity level and compliance certifications are evaluated for application suitability

The VTAN1111C from Stanley Electric Co meets all primary matching criteria and is classified as an active product with current manufacturing status.

Engineering Selection Recommendations

The VTAN1111C is a direct functional equivalent to the obsolete TAN1111C-TR based on matching electrical and mechanical specifications. Selection of the VTAN1111C is supported by the following engineering factors:

Product Status: The VTAN1111C maintains active manufacturing status, ensuring continued availability and supply chain stability compared to the obsolete TAN1111C-TR.

Electrical Compatibility: All critical electrical parameters—wavelength (940nm), forward voltage (1.22V), and maximum forward current (50mA)—are identical between the two parts. This ensures direct functional equivalence in circuit operation.

Mechanical Compatibility: Package format (0603 / 1608 Metric), mounting type (Surface Mount), and viewing angle (145°) are identical, enabling direct PCB layout compatibility without redesign.

Temperature Performance: The VTAN1111C operating temperature range (-40°C ~ 85°C) extends below the original specification (-30°C ~ 85°C), providing enhanced low-temperature performance margin.

Compliance: The VTAN1111C carries ROHS3 compliance certification and maintains REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

Moisture Sensitivity Consideration: The VTAN1111C has MSL rating of 4 (72 Hours) compared to the original MSL 1 (Unlimited). This requires adherence to moisture handling protocols during storage and assembly, with a 72-hour floor life limitation after package opening.

Frequently Asked Questions (FAQ)

Q: Can the VTAN1111C be used as a direct replacement for the TAN1111C-TR without circuit modification?

A: Yes. The VTAN1111C matches all critical electrical parameters (wavelength, forward voltage, maximum current) and mechanical specifications (package, mounting type, viewing angle). Direct substitution is possible without circuit redesign.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts, and does it affect substitution?

A: The TAN1111C-TR has MSL 1 (Unlimited shelf life), while the VTAN1111C has MSL 4 (72-hour floor life after package opening). The VTAN1111C requires moisture control during storage and assembly. This does not prevent substitution but requires implementation of appropriate moisture handling procedures per IPC-A-610 standards.

Q: Are there any temperature range differences that affect application suitability?

A: The VTAN1111C operating range (-40°C ~ 85°C) extends 10°C lower than the TAN1111C-TR (-30°C ~ 85°C). This provides additional margin for low-temperature applications and does not restrict substitution.

Q: Is the VTAN1111C compliant with current regulatory standards?

A: Yes. The VTAN1111C is ROHS3 compliant and REACH Unaffected, meeting current electronic component procurement regulations. The original TAN1111C-TR regulatory status is not specified in available documentation.

Q: What is the radiant intensity specification for the VTAN1111C?

A: The VTAN1111C specifies radiant intensity of 0.64mW/sr at 20mA forward current. This parameter was not provided for the original TAN1111C-TR.

Q: Can these parts be used interchangeably in existing PCB assemblies?

A: Yes. Both parts use identical 0603 (1608 Metric) surface-mount packages with top-view orientation. PCB footprints, solder pad layouts, and assembly processes are directly compatible.
