Key Parameters

Substitute Part Grouping Explanation

The Dialight 5530181F qualifies as a direct substitute for the 5530118F based on identical electrical and mechanical parameters. Substitution compatibility is determined by the following critical parameters:

• Dual-level configuration (2 High) with matching color combination (Blue + Red)
• Identical wavelength specifications (428nm Blue, 650nm Red)
• Matching luminous intensity ratings (13.15mcd Blue, 10mcd Red)
• Identical voltage requirements (4.6V Blue, 2V Red)
• Matching physical form factor (3mm T-1 lens, round domed top)
• Identical mounting orientation (Through Hole, Right Angle)
• Equivalent regulatory compliance (ROHS3, REACH Unaffected)

Both parts belong to the Dialight 553 series and maintain identical functional and physical characteristics, enabling direct board-level substitution without design modification.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5530181F provides full functional and physical equivalence to the 5530118F. Both components maintain Active product status with identical regulatory certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts may be based on inventory availability, lead time requirements, or procurement logistics, as no electrical or mechanical differentiation exists. The 5530181F currently maintains higher inventory levels (1303 pcs vs. 984 pcs), which may influence supply chain decisions. Both parts are suitable for direct substitution in existing circuit board designs without modification to schematic, layout, or bill of materials specifications.

Frequently Asked Questions (FAQ)

Q: Can the 5530181F be used as a direct replacement for the 5530118F on existing PCBs?

A: Yes. The 5530181F is electrically and mechanically identical to the 5530118F. No design changes, layout modifications, or schematic updates are required for substitution.

Q: Are the voltage and current requirements identical between these parts?

A: Yes. Both parts operate at 4.6V (Blue LED) and 2V (Red LED) with matching millicandela ratings of 13.15mcd (Blue) and 10mcd (Red).

Q: Do both parts have the same physical footprint and mounting orientation?

A: Yes. Both components feature identical 3mm T-1 through-hole right-angle mounting with round domed lens tops, ensuring mechanical compatibility without PCB layout changes.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the primary difference between these two part numbers?

A: The parts are functionally equivalent. Differences exist only in base product number designation (5530118 vs. 5530181) and current inventory levels, with no impact on electrical or mechanical performance.
