Substitute Part Grouping Explanation

The substitute part 5612301090F is classified as a manufacturer-recommended equivalent based on the following substitution criteria:

Maintained Parameters (Substitution Basis):

• Manufacturer: Dialight (same manufacturer ensures design consistency)
• Series: 561 (same product family)
• Color: Yellow (identical optical output)
• Configuration: Single (same electrical configuration)
• Current Rating: 20mA (identical operating current)
• Mounting Type: Through Hole (same PCB integration method)
• Lens Type: Diffused (same optical characteristics)
• RoHS Status: ROHS3 Compliant (equivalent environmental compliance)
• REACH Status: REACH Unaffected (equivalent regulatory status)

Allowable Variations:

• Voltage Rating: 2.2V (main part) to 2.4V (substitute) — within acceptable forward voltage tolerance for LED circuit board indicators
• Wavelength - Peak: 585nm to 590nm — within yellow spectrum range for visual equivalence
• Millicandela Rating: 34mcd to 10mcd — brightness variation acceptable for indicator applications
• Viewing Angle: 50° to 70° — both suitable for circuit board indicator use
• Lens Style: Diffused to Round with Domed Top — both diffused optical characteristics
• Lens Size: 5mm, T-1 3/4 — standard through-hole package dimension

Parameter Comparison

Engineering Selection Recommendations

The 5612301090F is the manufacturer-recommended substitute for the obsolete 5615301090F. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence for new designs and production continuity.

The substitute part is currently in active production status with 2403 units available in inventory, compared to the obsolete main part with limited remaining stock of 619 units. Selection of the substitute part ensures long-term supply chain stability and access to current manufacturing batches.

The forward voltage increase from 2.2V to 2.4V represents a standard tolerance variation within LED circuit board indicator specifications. The wavelength shift from 585nm to 590nm remains within the yellow spectrum range and maintains visual equivalence for indicator applications. The viewing angle expansion from 50° to 70° provides improved visibility characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 5612301090F directly replace the 5615301090F in existing designs?

A: Yes. Both parts share identical mounting type (through-hole), current rating (20mA), color (yellow), and lens type (diffused). The forward voltage difference of 0.2V falls within standard LED tolerance ranges for circuit board indicator applications.

Q: What is the impact of the brightness difference between the two parts?

A: The main part is rated at 34mcd while the substitute is rated at 10mcd. This represents a reduction in peak brightness. For indicator applications where the LED serves as a status signal rather than a primary light source, this variation is acceptable. Circuit designs relying on specific brightness levels should be evaluated against application requirements.

Q: Are there any PCB layout modifications required when switching to the substitute part?

A: No. Both parts use identical through-hole mounting and 5mm T-1 3/4 package dimensions. Existing PCB layouts require no modification.

Q: How does the increased viewing angle affect circuit board indicator performance?

A: The viewing angle increases from 50° to 70°, providing a wider field of visibility. This is a performance improvement for indicator applications and does not negatively impact functionality.

Q: What is the regulatory compliance status of the substitute part?

A: The 5612301090F maintains ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part. Both components are suitable for applications requiring these certifications.
