Substitute Part Grouping Explanation

Substitution of the BR1111C-TR is determined by the following critical parameters:

Primary Substitution Criteria:

Package / Case: 0603 (1608 Metric) surface mount form factor
Color: Red light emission
Mounting Type: Surface Mount
Wavelength - Dominant: 647nm red spectrum
Voltage - Forward (Vf): 1.7V nominal operation
Current - Test: 20mA test condition
Millicandela Rating: 11.7mcd brightness level
Lens Transparency: Diffused optical characteristic

Substitution Logic: Substitute parts are grouped into two categories based on optical and electrical compatibility:

Category 1 - Direct Diffused Red Substitutes (Highest Compatibility): Parts maintaining diffused lens transparency, 647nm wavelength, 1.7V forward voltage, and 11.7mcd brightness. These parts are electrically and optically equivalent to BR1111C-TR.

Category 2 - Clear Red Substitutes (Conditional Compatibility): Parts with clear lens transparency instead of diffused, operating at higher forward voltages (1.9V to 2.0V) and different brightness levels (60mcd to 240mcd). These parts require circuit design verification due to optical and electrical parameter differences.

Engineering Selection Recommendations

Recommended Primary Substitutes (Active Status, Diffused Lens):

The Dialight 5975112407F and 5975112402F represent the closest functional equivalents to BR1111C-TR. Both parts maintain identical electrical parameters (1.7V forward voltage, 20mA test current, 11.7mcd brightness) and optical characteristics (diffused lens, 647nm dominant wavelength). Both parts are in active production status, ensuring long-term availability. The primary difference is packaging format: 5975112407F is supplied in Tape & Reel (TR) format, while 5975112402F is supplied in Strip format. Height specification is 0.70mm compared to 0.80mm for BR1111C-TR, which is acceptable for standard PCB assembly processes. Viewing angle is 152° compared to 136°-141° for the original part, providing wider light distribution.

Secondary Substitutes (Active Status, Clear Lens):

The Dialight 5988020107F and 5988020102F (625nm wavelength, 240mcd) and 5988010107F and 5988010102F (635nm wavelength, 60mcd) are clear lens alternatives. These parts operate at 2.0V forward voltage, requiring circuit design adjustment compared to the 1.7V BR1111C-TR specification. The 5988020 series delivers significantly higher brightness (240mcd) suitable for applications requiring increased visibility. The 5988010 series provides moderate brightness (60mcd) closer to the original specification. Both series maintain 20mA test current and 0603 package compatibility. Würth Elektronik 150060RS75000 offers similar clear lens characteristics with 250mcd brightness and 2.0V forward voltage.

Alternative Substitute (Active Status, Intermediate Characteristics):

Kingbright APT1608SURCK operates at 1.95V forward voltage with 80mcd brightness and clear lens transparency. This part bridges electrical and optical characteristics between diffused and high-brightness clear lens alternatives. Viewing angle is 120°, narrower than BR1111C-TR, suitable for directed indication applications.

Compliance Status:

All recommended substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory requirements of BR1111C-TR. Moisture sensitivity levels vary across substitutes (MSL 2 to MSL 4), requiring verification against specific storage and assembly conditions.

Frequently Asked Questions (FAQ)

Q: Can 5975112407F directly replace BR1111C-TR without circuit modification?

A: Yes. The 5975112407F maintains identical forward voltage (1.7V), test current (20mA), brightness (11.7mcd), and diffused lens characteristics. The 0.70mm height versus 0.80mm original height is within standard PCB assembly tolerances. Wider viewing angle (152° versus 136°-141°) is functionally compatible for indication applications.

Q: What is the primary difference between diffused and clear lens substitutes?

A: Diffused lens parts (5975112407F, 5975112402F) scatter light uniformly across a wide viewing angle, producing a soft glow suitable for general indication. Clear lens parts (5988020107F, 5988010107F, 150060RS75000, APT1608SURCK) concentrate light in a narrower beam with higher brightness, suitable for directed visibility. Diffused parts maintain the original BR1111C-TR optical behavior; clear lens parts require application-specific evaluation.

Q: Why do clear lens substitutes operate at higher forward voltages?

A: Clear lens LED designs typically require higher forward voltages (1.9V to 2.0V) compared to diffused designs (1.7V to 1.8V) due to different semiconductor junction structures and optical element configurations. Circuit design must accommodate this voltage difference through resistor or current-limiting adjustments.

Q: Are all substitute parts available in the same packaging formats?

A: No. BR1111C-TR is supplied in Cut Tape (CT) format. Substitute parts are available in multiple formats: Tape & Reel (TR), Strip, Cut Tape (CT), and Digi-Reel®. Selection depends on assembly equipment compatibility and procurement volume requirements. Verify packaging format with supplier before ordering.

Q: What is the significance of product status (Active vs. Obsolete)?

A: Active status indicates current production and long-term availability. Obsolete status indicates discontinued production with limited remaining inventory. BR1111C-TR is obsolete; all recommended substitutes are active, ensuring supply chain continuity for new designs and production runs.

Q: Can FR1101C-2005-M-TR substitute for BR1111C-TR?

A: No. FR1101C-2005-M-TR is a clear lens part with colorless lens color, 623nm wavelength, 1.9V forward voltage, and 5mA test current. These parameters differ significantly from BR1111C-TR's diffused red lens, 647nm wavelength, 1.7V forward voltage, and 20mA test current. This part is not functionally equivalent.

Q: What moisture sensitivity level should be considered for assembly?

A: BR1111C-TR specifies MSL 4 (72 Hours). Most substitute parts specify MSL 2 or MSL 3, indicating lower moisture sensitivity and less stringent storage requirements. Lower MSL ratings provide manufacturing flexibility; verify specific MSL requirements against assembly facility capabilities and storage conditions.

Q: How does viewing angle affect LED substitution?

A: Viewing angle determines light distribution pattern. BR1111C-TR specifies 136°-141°. Substitutes range from 120° (narrower, directed) to 170° (wider, diffuse). Narrower angles concentrate brightness in a specific direction; wider angles distribute light across a broader area. Application requirements determine acceptable viewing angle ranges.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching BR1111C-TR regulatory requirements. No additional compliance verification is necessary for standard applications.

Q: What is the difference between 5975112407F and 5975112402F?

A: Both parts are electrically and optically identical (1.7V, 20mA, 11.7mcd, 647nm, diffused lens). The primary difference is packaging: 5975112407F is supplied in Tape & Reel (TR) format for automated assembly; 5975112402F is supplied in Strip format for manual or semi-automated assembly. Select based on assembly process requirements.
