LED Circuit Board Indicator 6255T5LC Equivalent & Substitute Parts

Part Overview

The 6255T5LC is a Surface Mount Right Angle LED Circuit Board Indicator manufactured by Visual Communications Company (VCC). This component is a single green tinted LED with a round domed top lens, designed for 1.8V operation at 2mA current. The part is classified as Obsolete, making identification of compatible substitute components essential for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility while accommodating potential differences in physical form factor and lens dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6255T5LC are identified based on the following critical electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Color: Green (565nm wavelength range acceptable with ±5nm tolerance)
• Configuration: Single LED
• Current Rating: 2mA (exact match required)
• Voltage Rating: 1.8V (exact match required)
• Millicandela Rating: 5mcd (exact match required)

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount, Right Angle (exact match required)
• Lens Style: Round with Domed Top (exact match required)
• Lens Size: Physical dimensions must accommodate PCB layout constraints

Regulatory & Environmental Requirements:

• RoHS3 Compliance (mandatory for equivalent substitution)
• REACH Unaffected status (mandatory for equivalent substitution)
• Moisture Sensitivity Level: 2 or better (acceptable for equivalent substitution)

The substitute part 5912304013F (Dialight) meets all critical electrical parameters and maintains Surface Mount Right Angle mounting compatibility. Physical form factor differences (3mm T-1 lens size versus 5.3×4.6×4.8mm) require PCB layout verification but do not preclude functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 5912304013F (Dialight)

The 5912304013F qualifies as a functional equivalent based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters match exactly: 2mA current, 1.8V voltage, 5mcd brightness, and green color specification. The 5nm wavelength difference (570nm versus 565nm) remains within acceptable green LED color space tolerances and does not affect circuit functionality.

Mechanical Compatibility: Both components feature Surface Mount Right Angle mounting and Round Domed Top lens styling. The physical dimension difference (3mm T-1 versus 5.3×4.6×4.8mm) requires PCB layout verification to confirm footprint compatibility with existing circuit board designs.

Regulatory Compliance: The substitute part maintains ROHS3 compliance and REACH Unaffected status, meeting all regulatory requirements equivalent to the original component.

Product Availability: The 5912304013F is classified as Active product status with 22,352 units in stock, providing reliable long-term availability compared to the Obsolete 6255T5LC.

Environmental Advantages: The substitute offers improved Moisture Sensitivity Level (2 with 1-year shelf life versus 2A with 4-week shelf life), reducing storage and handling constraints.

Implementation Consideration: PCB layout modification may be required due to physical form factor differences. Verify mounting footprint compatibility before design finalization.

Frequently Asked Questions (FAQ)

Q: Can the 5912304013F directly replace the 6255T5LC without PCB modifications?

A: Electrical substitution is direct and requires no circuit modifications. However, physical form factor differences (3mm T-1 lens versus 5.3×4.6×4.8mm) may require PCB layout verification. If the original PCB footprint accommodates the smaller 3mm lens size, no modifications are necessary. If not, PCB redesign is required.

Q: What is the significance of the 5nm wavelength difference (565nm to 570nm)?

A: Both wavelengths fall within the standard green LED color specification range. The 5nm difference is imperceptible to human vision and does not affect circuit functionality or visual indication performance.

Q: Why is the 6255T5LC classified as Obsolete?

A: Obsolete status indicates the manufacturer (VCC) has discontinued production. The 5912304013F (Dialight) is an Active product with ongoing manufacturing support, making it the recommended choice for new designs and ongoing production requirements.

Q: Does the improved Moisture Sensitivity Level (MSL) of the substitute affect compatibility?

A: No. The substitute's improved MSL rating (2 with 1-year shelf life versus 2A with 4-week shelf life) is a performance advantage. It provides extended storage capability without affecting electrical or mechanical compatibility.

Q: Are there any compliance concerns with substituting the Dialight part?

A: No. Both components maintain ROHS3 compliance and REACH Unaffected status. All regulatory requirements are equivalent.

Q: What is the viewing angle difference, and does it matter?

A: The original 6255T5LC does not specify a viewing angle. The substitute specifies 50° viewing angle, which is a standard specification for this LED category. This provides additional technical documentation without affecting compatibility.

Q: Can I use the 5912304013F in existing inventory of 6255T5LC applications?

A: Yes, provided PCB footprint compatibility is confirmed. All electrical parameters are identical. Physical form factor verification is the only requirement before implementation.
