SMP2-HC Equivalent & Substitute Parts

Part Overview

The SMP2-HC is a red 628nm LED indicator manufactured by Bivar Inc., configured as a discrete 2V 2-PLCC surface mount device. This component is currently classified as obsolete, necessitating the identification of functional equivalents for ongoing production and maintenance applications. The substitute part SMTL2-HC maintains identical electrical and optical specifications while offering active product status and improved packaging options.

Key Parameters

Substitute Part Grouping Explanation

The SMTL2-HC qualifies as a parametric equivalent to the SMP2-HC based on the following critical parameters:

• Optical Characteristics: Identical dominant wavelength (628nm), color (Red), and brightness rating (11mcd)
• Electrical Performance: Identical forward voltage (2V) and test current (20mA)
• Mechanical Compatibility: Identical package type (2-PLCC), mounting method (Surface Mount), lens configuration (Round with Flat Top, Clear), and primary dimensions (3.20mm L x 2.80mm W)
• Environmental Tolerance: Identical Moisture Sensitivity Level (4, 72 Hours)
• Regulatory Compliance: Both classified under ECCN EAR99 and HTSUS 8541.41.0000

Substitution is valid where the SMP2-HC is no longer available due to obsolescence, as the SMTL2-HC maintains complete electrical and mechanical parity.

Parameter Comparison

Engineering Selection Recommendations

The SMTL2-HC is the direct functional replacement for the SMP2-HC. The obsolete status of the SMP2-HC necessitates transition to the SMTL2-HC for new designs and component replenishment. The SMTL2-HC maintains active product status and carries RoHS3 compliance certification. The height differential of 0.10mm (2.00mm versus 2.10mm maximum) falls within standard PCB assembly tolerances and does not impact performance in applications designed for 2-PLCC red LED indicators at 2V/20mA specifications. Tape & Reel (TR) packaging of the SMTL2-HC provides superior handling efficiency for production environments compared to alternate packaging configurations.

Frequently Asked Questions (FAQ)

Q: Can the SMTL2-HC directly replace the SMP2-HC in existing PCB layouts? A: Yes. The SMTL2-HC maintains identical mechanical dimensions (3.20mm L x 2.80mm W) and the same 2-PLCC package footprint as the SMP2-HC. The maximum height difference of 0.10mm is within standard component tolerance specifications.

Q: Are the optical and electrical characteristics identical? A: Yes. Both parts specify 628nm dominant wavelength red color, 11mcd brightness, 2V forward voltage, and 20mA test current with a 120° viewing angle. Optical performance is equivalent.

Q: What is the primary difference between the SMP2-HC and SMTL2-HC? A: The SMTL2-HC is the active product offering with RoHS3 compliance and Tape & Reel packaging. The SMP2-HC has reached end-of-life status. Functionally, they are equivalent for all red LED indicator applications requiring 2V/20mA 2-PLCC surface mount components.

Q: Does the change in packaging from individual to Tape & Reel affect component performance? A: No. Tape & Reel (TR) packaging affects logistics and handling efficiency but not electrical or optical performance. The component specifications remain identical.

Q: Are both parts suitable for the same environmental conditions? A: Yes. Both parts carry identical Moisture Sensitivity Level (4, 72 Hours) ratings and the same ECCN/HTSUS classifications, confirming equivalent environmental specifications.
