LED Circuit Board Indicator 5306H1LC Equivalent & Substitute Parts

Part Overview

The 5306H1LC is a red LED circuit board indicator manufactured by Visual Communications Company (VCC), designed for through-hole, right-angle PCB mounting applications. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance requirements. The 5306H1LC operates at 1.8V with a 7mA current rating and delivers 2.3mcd luminous intensity in a standard 5mm T-1 3/4 round domed lens package. Identifying compatible substitutes ensures design continuity and supply chain reliability for legacy and new applications requiring red LED indicators with similar electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5306H1LC is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Color: Red
• Configuration: Single LED
• Mounting Type: Through Hole, Right Angle
• Lens Size: 5mm, T-1 3/4 form factor
• Lens Style: Round domed configuration

Allowable Parameter Variance:

• Voltage Rating: 1.8V to 1.9V (within typical forward voltage tolerance for red LEDs)
• Current Rating: 7mA to 10mA (operational current range for similar red LED indicators)
• Wavelength - Peak: 627nm to 635nm (red spectrum range)
• Millicandela Rating: 2.3mcd to 40mcd (luminous intensity variation acceptable for indicator applications)
• Viewing Angle: Specified or unspecified (does not restrict substitution)
• Lens Type: Clear or Diffused (both acceptable for indicator function)

The XVB1LUR50D from SunLED meets all mandatory compatibility criteria and falls within allowable parameter variance ranges, qualifying it as a direct substitute for the obsolete 5306H1LC.

Engineering Selection Recommendations

The XVB1LUR50D from SunLED is qualified as a direct substitute for the obsolete 5306H1LC based on the following engineering criteria:

Compliance & Regulatory Alignment: Both components maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental standards. Both components carry EAR99 ECCN classification and fall under the same HTSUS code (8541.41.0000), confirming regulatory equivalence.

Mechanical & Electrical Compatibility: The XVB1LUR50D maintains identical mechanical form factor (5mm T-1 3/4 through-hole right-angle mounting) and electrical configuration (single red LED). The forward voltage increase from 1.8V to 1.9V and current rating increase from 7mA to 10mA represent standard operational variance within red LED indicator specifications and do not compromise circuit compatibility when proper current-limiting resistors are employed.

Product Status Advantage: The XVB1LUR50D is classified as Active, ensuring long-term availability and supply chain continuity compared to the obsolete 5306H1LC. Current inventory of 8382 units provides immediate procurement capability.

Luminous Intensity Consideration: The XVB1LUR50D delivers 40mcd compared to the 5306H1LC's 2.3mcd. This increased brightness is acceptable for indicator applications and may provide improved visibility in high-ambient-light environments. The diffused lens type on the XVB1LUR50D provides wider light distribution compared to the unspecified lens type on the original component.

Frequently Asked Questions (FAQ)

Q: Can the XVB1LUR50D be used as a direct drop-in replacement for the 5306H1LC?

A: Yes, the XVB1LUR50D qualifies as a direct substitute. Both components share identical mechanical mounting (5mm T-1 3/4 through-hole right-angle), lens style (round domed), and electrical configuration (single red LED). Circuit design modifications are not required; however, current-limiting resistor values may require adjustment due to the 0.1V forward voltage difference and 3mA current rating increase.

Q: What is the significance of the wavelength difference between 635nm and 627nm?

A: Both wavelengths fall within the red spectrum range for LED indicators. The 8nm difference is imperceptible to human vision and does not affect functional performance in indicator applications. Both components produce red light suitable for status indication purposes.

Q: Why is the millicandela rating significantly higher on the XVB1LUR50D?

A: The XVB1LUR50D delivers 40mcd versus 2.3mcd on the 5306H1LC. This increased luminous intensity results from improved LED die efficiency in the SunLED component and the diffused lens design, which provides wider light distribution. For indicator applications, higher brightness is generally advantageous and does not create compatibility issues.

Q: Does the diffused lens type on the XVB1LUR50D affect substitution suitability?

A: No. The diffused lens on the XVB1LUR50D provides wider viewing angle (60°) and more uniform light distribution compared to the unspecified lens type on the 5306H1LC. This represents a functional improvement for indicator visibility and does not compromise substitution compatibility.

Q: Are there any compliance or regulatory concerns with substituting the XVB1LUR50D?

A: No compliance concerns exist. Both components are ROHS3 compliant, carry identical MSL ratings (Level 1 Unlimited), and share the same ECCN and HTSUS classifications. The XVB1LUR50D meets all regulatory requirements for direct substitution.

Q: What is the advantage of selecting the XVB1LUR50D over the obsolete 5306H1LC?

A: The XVB1LUR50D is classified as Active with 8382 units in current inventory, ensuring reliable long-term supply availability. The 5306H1LC is obsolete with limited remaining stock. The XVB1LUR50D provides superior brightness, wider viewing angle, and active manufacturer support, making it the preferred choice for new designs and ongoing production requirements.

Q: Are circuit modifications required when substituting the XVB1LUR50D?

A: Minor adjustments to current-limiting resistor values may be necessary due to the 0.1V forward voltage increase (1.8V to 1.9V) and 3mA current rating increase (7mA to 10mA). Recalculate resistor values using the XVB1LUR50D's electrical specifications to maintain proper LED operating current. No other circuit modifications are required.
