SM0603UOC Equivalent & Substitute Parts

Part Overview

The SM0603UOC is an orange surface-mount LED indicator manufactured by Bivar Inc., featuring a dominant wavelength of 625nm and a brightness rating of 80mcd. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and production continuity. The 0603 (1608 Metric) package format and specific electrical characteristics define the substitution parameters for this discrete LED indication component.

Substitute Part Grouping Explanation

Substitute parts for the SM0603UOC are identified based on the following critical parameters that determine functional and mechanical compatibility:

Package Compatibility: All substitute parts must utilize the 0603 (1608 Metric) surface-mount package format with identical physical dimensions (1.60mm L x 0.80mm W, 0.80mm maximum height).

Electrical Compatibility: Forward voltage (Vf) and test current specifications must remain within acceptable operating ranges for the intended application circuit. The standard test current of 20mA defines the brightness rating context.

Optical Characteristics: Viewing angle of 130° and lens configuration (Rectangle with Flat Top, 1.00mm x 0.80mm) establish the optical performance baseline.

Mechanical Compatibility: Lens color (Colorless), lens transparency (Clear), and mounting type (Surface Mount) must remain consistent.

Environmental Compliance: Moisture Sensitivity Level (MSL) rating of 4 (72 Hours) and applicable regulatory classifications (ECCN, HTSUS) define handling and compliance requirements.

The SM0603AC substitute part shares the identical package format, mounting type, lens configuration, and environmental specifications while differing in color (Amber vs. Orange) and brightness rating (6mcd vs. 80mcd).

Parameter Comparison

Engineering Selection Recommendations

The SM0603AC represents an active-status substitute for the obsolete SM0603UOC. Both components share identical mechanical compatibility, package format, and environmental specifications. The primary differences are wavelength (625nm vs. 607nm dominant), brightness rating (80mcd vs. 6mcd), and forward voltage (2.1V vs. 2V).

Selection of SM0603AC as a substitute requires circuit-level evaluation of color perception requirements and brightness specifications. The amber wavelength (607nm) differs from the orange wavelength (625nm), which may affect visual indication in applications where specific color discrimination is required. The significantly lower brightness rating (6mcd vs. 80mcd) necessitates assessment of visibility requirements in the target application environment.

Both parts maintain RoHS compliance status and identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000), supporting equivalent supply chain and environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can SM0603AC be used as a direct replacement for SM0603UOC in all applications?

A: SM0603AC shares identical package format, mounting type, and environmental specifications with SM0603UOC. However, the amber color (607nm dominant wavelength) differs from the orange color (625nm dominant wavelength), and the brightness rating is significantly lower (6mcd vs. 80mcd). Substitution is valid only when the application does not require specific orange color indication or the higher brightness level of the original part.

Q: What are the mechanical compatibility requirements for substitution?

A: Both parts utilize the 0603 (1608 Metric) surface-mount package with identical physical dimensions (1.60mm L x 0.80mm W, 0.80mm maximum height), lens configuration (Rectangle with Flat Top, 1.00mm x 0.80mm), and mounting type (Surface Mount). Mechanical compatibility is fully maintained.

Q: How do the electrical specifications compare?

A: The forward voltage differs slightly (2.1V for SM0603UOC vs. 2V for SM0603AC), and both parts operate at the same test current of 20mA. Circuit designs must accommodate the 0.1V difference in forward voltage when selecting current-limiting resistor values.

Q: Are there environmental or compliance differences between these parts?

A: Both parts share identical Moisture Sensitivity Level (MSL) ratings of 4 (72 Hours), ECCN classification (EAR99), and HTSUS code (8541.41.0000). SM0603AC carries RoHS3 compliance certification. Environmental handling and regulatory requirements are equivalent.

Q: What is the primary reason for substitution?

A: SM0603UOC is classified as obsolete, making SM0603AC the active-status alternative from the same manufacturer. Continued production and supply availability favor the active-status part for new designs and production continuity.
