Key Parameters

Substitute Part Grouping Explanation

The SLR-332VC3F from Rohm Semiconductor qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• Color: Red
• Lens Size: 3.20mm Dia
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole
• Package / Case: Radial
• Height (Max): 4.60mm (within tolerance of 4.70mm)
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Operational Compatibility: The SLR-332VC3F operates at 2V forward voltage with a 10mA test current, compared to the LN276RCPX at 2.2V and 20mA. Both components function within standard red LED operating ranges and share identical mechanical form factors, enabling direct pin-compatible substitution in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The SLR-332VC3F is the designated substitute for the obsolete LN276RCPX. Selection is based on:

Product Status: The SLR-332VC3F maintains active product status with Rohm Semiconductor, ensuring ongoing availability and supply chain continuity compared to the obsolete LN276RCPX.

Compliance & Certifications: The SLR-332VC3F carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Mechanical Compatibility: Both components share identical 3.2mm lens diameter, round domed lens style, radial package configuration, and through-hole mounting type, enabling direct PCB footprint compatibility.

Electrical Operation: The SLR-332VC3F operates at 2V forward voltage versus 2.2V for the LN276RCPX, representing a 0.2V reduction within acceptable LED operating margins. The 10mA test current versus 20mA reflects standard specification methodology differences between manufacturers and does not preclude functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SLR-332VC3F be used as a direct replacement for the LN276RCPX in existing designs?

A: Yes. Both components share identical mechanical form factors (3.2mm round domed lens, radial package, through-hole mounting) and are pin-compatible. The 0.2V forward voltage difference (2V vs 2.2V) falls within standard LED operating tolerances and does not require circuit redesign.

Q: What is the difference in brightness between these two LEDs?

A: The SLR-332VC3F is rated at 10mcd while the LN276RCPX is rated at 1.5mcd. The higher brightness of the substitute part is a result of improved LED technology in the active Rohm component and does not create compatibility issues in standard indication applications.

Q: Are there any compliance differences between the two parts?

A: The LN276RCPX is obsolete with no current compliance documentation. The SLR-332VC3F is an active component with RoHS3 compliance and REACH unaffected status, meeting current regulatory standards for new designs and procurement.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the LN276RCPX and SLR-332VC3F carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the wavelength difference between these LEDs?

A: The LN276RCPX has a peak wavelength of 700nm. The SLR-332VC3F has a dominant wavelength of 630nm. Both fall within the red LED spectrum and are visually indistinguishable in standard indication applications.
