DB1111C-TR Equivalent & Substitute Parts Reference

Part Overview

The DB1111C-TR is a blue diffused SMD LED manufactured by Stanley Electric Co, designed for indication applications with a dominant wavelength of 470nm and forward voltage of 3.3V. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing production and design requirements. The 0603 (1608 Metric) package format and diffused lens configuration define the functional category for substitution analysis.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

Primary Compatibility Criteria:

• Package / Case: 0603 (1608 Metric)
• Color: Blue
• Lens Transparency: Diffused
• Mounting Type: Surface Mount
• Lens Style: Rectangle with Flat Top

Secondary Compatibility Parameters:

• Wavelength - Dominant: 470nm or 473nm (within blue spectrum range)
• Voltage - Forward (Vf): 3.3V or 3.4V (acceptable operating range)
• Physical dimensions: 1.60mm L x 0.80mm W (identical across all parts)

All four substitute parts (HSMN-C190, HSMN-C191, HSMR-C190, HSMR-C191) meet the primary compatibility criteria. Differences in millicandela rating, viewing angle, and test current reflect performance enhancements in active alternatives. The HSMN series maintains 470nm wavelength matching; the HSMR series operates at 473nm with increased brightness.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Wavelength-Matched):

HSMN-C190 and HSMN-C191 maintain the 470nm dominant wavelength specification of the DB1111C-TR. Both parts are manufactured by Broadcom Limited and carry Active product status with ROHS3 compliance. HSMN-C190 is supplied in Cut Tape (CT) & Digi-Reel® packaging, while HSMN-C191 is supplied in Tape & Reel (TR) format. The primary distinction is maximum height: HSMN-C190 at 0.80mm matches the original specification, while HSMN-C191 is reduced to 0.60mm. Both operate at 3.3V forward voltage with improved moisture sensitivity (MSL 2A vs. MSL 4).

For Enhanced Performance (Higher Brightness):

HSMR-C190 and HSMR-C191 operate at 473nm dominant wavelength with 3.4V forward voltage and deliver 55mcd brightness compared to the original 14mcd. These parts are suitable for applications where increased luminous intensity is acceptable within the blue spectrum range. HSMR-C190 is supplied in Cut Tape (CT) & Digi-Reel® packaging at 0.80mm height; HSMR-C191 is supplied in Tape & Reel (TR) format at 0.60mm height.

Compliance Considerations:

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The improved moisture sensitivity level (MSL 2A, 4 weeks) of all Broadcom alternatives provides superior handling characteristics compared to the original MSL 4 specification.

Frequently Asked Questions (FAQ)

Q: Can HSMN-C190 or HSMN-C191 be used as direct replacements for DB1111C-TR?

A: Yes. Both HSMN-C190 and HSMN-C191 maintain the 470nm dominant wavelength and 3.3V forward voltage of the original part. The 0603 package, diffused lens, and surface mount configuration are identical. Selection between these two depends on PCB height constraints: HSMN-C190 at 0.80mm maximum height or HSMN-C191 at 0.60mm maximum height.

Q: What is the difference between HSMN and HSMR series substitutes?

A: The HSMN series maintains 470nm wavelength matching the DB1111C-TR at 3.3V operation. The HSMR series operates at 473nm wavelength with 3.4V forward voltage and delivers significantly higher brightness (55mcd vs. 35mcd). The HSMR series is suitable for applications where increased luminous intensity is required within acceptable wavelength tolerance.

Q: Are packaging differences between Cut Tape and Tape & Reel significant for substitution?

A: Packaging format (Cut Tape vs. Tape & Reel) affects supply chain logistics and handling but does not impact electrical or mechanical compatibility. HSMN-C190 and HSMR-C190 are supplied in Cut Tape (CT) & Digi-Reel® format; HSMN-C191 and HSMR-C191 are supplied in Tape & Reel (TR) format. Selection depends on assembly equipment and procurement requirements.

Q: Does the height difference between 0.80mm and 0.60mm affect PCB layout?

A: Height differences may affect PCB clearance and component placement. HSMN-C191 and HSMR-C191 at 0.60mm maximum height provide reduced profile compared to 0.80mm alternatives. Verify PCB design constraints before selecting the reduced-height variant.

Q: What is the significance of the improved MSL rating in substitute parts?

A: The DB1111C-TR carries MSL 4 (72 hours), while all Broadcom substitutes carry MSL 2A (4 weeks). Lower MSL ratings indicate superior moisture resistance and extended shelf life. This improvement reduces risk of moisture-induced failures during storage and handling.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts (HSMN-C190, HSMN-C191, HSMR-C190, HSMR-C191) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can HSMR-C190 or HSMR-C191 be used if the application requires 470nm wavelength?

A: HSMR series parts operate at 473nm dominant wavelength, a 3nm shift from the 470nm specification. This wavelength difference is within the blue spectrum range but may be perceptible in color-critical applications. Verify application tolerance for wavelength variation before substitution.
