Substitute Part Grouping Explanation

Substitution of the SECU1713C-S yellow 0603 SMD LED is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Forward voltage (Vf) of 2.1V typical
• Test current of 20mA
• Dominant wavelength of 570nm (yellow spectrum)
• Millicandela rating of 300mcd

Mechanical Parameters:

• Package format: 0603 (1608 Metric)
• Physical dimensions: 1.60mm L × 0.80mm W
• Maximum height: 1.48mm
• Lens style: Round with domed top
• Lens diameter: 0.92mm
• Viewing angle: 60°
• Mounting type: Surface Mount

Compliance & Regulatory Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 3 (168 Hours)
• Packaging: Tape & Reel (TR)

Only components matching all specified parameters across these three categories qualify as direct substitutes. No parameter relaxation or tolerance variation is applied beyond the values explicitly provided.

Engineering Selection Recommendations

The SECU1713C-S yellow 0603 SMD LED is an Active product with full ROHS3 compliance and standard MSL 3 moisture sensitivity rating suitable for standard reflow soldering processes. Selection of this component or its direct equivalents is appropriate for indication circuit applications requiring yellow light emission at 570nm wavelength with 300 millicandela brightness output.

Component selection should be based on:

1. Product Status Verification: Confirm Active status for long-term supply chain continuity
2. Compliance Requirements: Verify ROHS3 compliance meets end-product regulatory requirements
3. Moisture Handling: Confirm MSL 3 (168 Hours) compatibility with manufacturing process conditions
4. Package Compatibility: Validate 0603 (1608 Metric) package fits PCB layout and assembly equipment specifications
5. Electrical Circuit Design: Confirm 2.1V forward voltage and 20mA test current align with circuit design parameters

Direct substitution with SECU1713C-S maintains full electrical, mechanical, and regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: What makes SECU1713C-S a direct substitute for itself?

A: The SECU1713C-S is listed as its own substitute because all electrical parameters (2.1V forward voltage, 20mA test current, 570nm wavelength, 300mcd brightness), mechanical specifications (0603 package, 1.60 × 0.80mm dimensions, 1.48mm height, round domed lens), and compliance certifications (ROHS3, MSL 3) are identical across all units from Sanken Electric USA Inc.

Q: Can this LED be used in applications requiring different wavelengths?

A: No. The SECU1713C-S is specified for 570nm dominant wavelength (yellow spectrum). Applications requiring different wavelengths require different LED part numbers with corresponding wavelength specifications.

Q: Is the 0603 package compatible with all PCB assembly equipment?

A: The 0603 (1608 Metric) package is a standard surface mount format. Compatibility depends on specific assembly equipment specifications. Verify equipment capability for 0603 component placement and reflow soldering before production.

Q: What does MSL 3 (168 Hours) mean for manufacturing?

A: MSL 3 indicates the component can be exposed to moisture for up to 168 hours at specified temperature and humidity conditions before soldering. Components must be stored in dry conditions and baked according to IPC standards if moisture exposure limits are exceeded.

Q: Are there any restrictions on forward voltage or current operation?

A: The SECU1713C-S is specified with a typical forward voltage of 2.1V and test current of 20mA. Circuit design must ensure operation within these parameters. Exceeding specified current ratings reduces component lifespan and brightness output.

Q: What is the viewing angle significance?

A: The 60° viewing angle indicates the LED produces visible light output within a 60-degree cone from the optical axis. Applications requiring wider or narrower light distribution require different lens styles or LED part numbers.

Q: Is ROHS3 compliance required for all applications?

A: ROHS3 compliance is mandatory for products sold in European Union markets and many other regions. Verify regulatory requirements for target markets before component selection.
