SMP2-AC Equivalent & Substitute Parts

Part Overview

The SMP2-AC is an amber LED indicator manufactured by Bivar Inc., designed for discrete indication applications. This component features a 607nm dominant wavelength with 15mcd luminous intensity in a compact 2-PLCC surface mount package. The SMP2-AC is classified as obsolete, making identification of compatible substitute parts essential for ongoing production support and design continuity. Equivalent parts must maintain identical electrical performance and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SMP2-AC is based on strict parameter matching across electrical and mechanical characteristics. The substitute part SMTL2-AC is classified as a parametric equivalent because it maintains all critical specifications:

Electrical Parameters (Must Match):

• Forward voltage: 2V
• Test current: 20mA
• Millicandela rating: 15mcd
• Wavelength - dominant: 607nm
• Viewing angle: 120°

Mechanical Parameters (Must Match):

• Package type: 2-PLCC
• Lens style: Round with Flat Top
• Lens transparency: Clear
• Mounting type: Surface Mount
• Footprint dimensions: 3.20mm L x 2.80mm W

Allowable Variation:

• Height maximum: 2.10mm (substitute) versus 2.00mm (original) — within tolerance for standard PCB assembly clearances
• Packaging format: Tape & Reel (substitute) versus bulk (original) — does not affect component performance

Engineering Selection Recommendations

The SMTL2-AC is the direct parametric equivalent for the obsolete SMP2-AC. Selection of SMTL2-AC is based on the following engineering criteria:

Product Status Consideration: The SMP2-AC is classified as obsolete. The SMTL2-AC maintains active product status with Bivar Inc., ensuring continued availability and manufacturing support.

Compliance and Certification: The SMTL2-AC carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both parts share identical MSL rating (4, 72 Hours), ensuring equivalent moisture handling protocols during storage and assembly.

Electrical and Optical Performance: All critical electrical parameters are identical: 2V forward voltage, 20mA test current, 15mcd luminous intensity, and 607nm dominant wavelength. Optical characteristics including 120° viewing angle and clear lens transparency are maintained.

Mechanical Compatibility: Both parts utilize the 2-PLCC package with identical footprint dimensions (3.20mm L x 2.80mm W). The height difference of 0.10mm (2.10mm maximum for SMTL2-AC versus 2.00mm for SMP2-AC) is within standard PCB assembly clearance tolerances and does not affect component placement or functionality.

Packaging Format: The SMTL2-AC is supplied in Tape & Reel format, which is standard for high-volume production environments and provides improved handling efficiency compared to bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can SMTL2-AC be used as a direct replacement for SMP2-AC in existing PCB designs?

A: Yes. The SMTL2-AC is a parametric equivalent with identical electrical performance, optical characteristics, and mechanical footprint. No PCB layout modifications are required. The 0.10mm height difference is within standard assembly tolerances.

Q: Are there any differences in soldering or assembly procedures?

A: No. Both components use identical 2-PLCC surface mount packaging and require the same soldering profile and assembly handling procedures. MSL rating is identical at level 4 (72 Hours).

Q: What is the significance of the height difference between SMP2-AC (2.00mm) and SMTL2-AC (2.10mm)?

A: The 0.10mm difference is negligible for standard PCB assembly. This variation falls within typical component tolerance ranges and does not affect clearance to adjacent components or conformal coating processes in standard manufacturing environments.

Q: Why is SMTL2-AC recommended over SMP2-AC?

A: The SMP2-AC is obsolete and no longer manufactured. The SMTL2-AC is an active product with identical specifications, ensuring long-term availability, manufacturing support, and ROHS3 compliance.

Q: Are the electrical characteristics guaranteed to be identical?

A: Yes. Forward voltage (2V), test current (20mA), luminous intensity (15mcd), dominant wavelength (607nm), and viewing angle (120°) are identical between both parts. These parameters determine functional equivalence.

Q: What packaging formats are available for each part?

A: SMP2-AC is supplied in bulk packaging. SMTL2-AC is supplied in Tape & Reel format, which is standard for automated assembly and provides improved component handling and traceability.

Q: Are there any compliance or certification differences?

A: The SMTL2-AC carries ROHS3 compliance certification. Both parts share identical MSL rating and ECCN/HTSUS classifications, ensuring equivalent regulatory and environmental compliance.
