Dialight 5615501050 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5615501050 is a 5mm red LED circuit board indicator designed for through-hole mounting applications. This part operates at 2.2V with a 20mA forward current and delivers 125 millicandela brightness with a 24° viewing angle. The component features a clear lens with round domed top construction in the T-1 3/4 form factor.

The 5615501050 carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications currently using this component.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

The parts 5505504F, 5505505010F, 5615501050F, and 5615501100F are all active production components with ROHS3 compliance. These parts maintain full electrical and mechanical compatibility with the obsolete 5615501050.

For applications requiring RoHS compliance, any of the four substitute parts satisfy regulatory requirements. The 5615501050F and 5615501100F remain within the same 561 series as the original part, providing design continuity. The 5505504F and 5505505010F are from the 550 series but deliver identical electrical performance and mechanical form factor.

Inventory Availability:

All substitute parts maintain active stock levels. Selection between substitutes should prioritize design requirements and supply chain considerations rather than electrical performance, as all options are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 5505504F replace the 5615501050 in existing designs?

A: Yes. The 5505504F maintains identical electrical specifications (20mA, 2.2V, 125mcd, 24° viewing angle) and mechanical form factor (5mm T-1 3/4 through-hole). The primary difference is series designation (550 versus 561) and active product status with ROHS3 compliance.

Q: What is the difference between 5615501050F and 5615501100F?

A: Both parts are from the 561 series with identical electrical ratings. The 5615501050F does not specify lens style or lens size in the provided data, while the 5615501100F explicitly documents round domed top construction in 5mm T-1 3/4 form factor. Both are ROHS3 compliant active parts.

Q: Is the 5615501050 still available for procurement?

A: The 5615501050 carries obsolete product status. Current inventory exists (1029 pcs), but no new production is scheduled. For new designs or long-term supply assurance, selection of an active substitute part is recommended.

Q: Do all substitute parts meet RoHS requirements?

A: The original 5615501050 is RoHS non-compliant. All four substitute parts (5505504F, 5505505010F, 5615501050F, 5615501100F) are ROHS3 compliant. Applications requiring RoHS certification must use one of these substitutes.

Q: Are there mechanical differences between the 550 and 561 series substitutes?

A: Based on provided specifications, the 5505504F and 5505505010F (550 series) and the 5615501050F and 5615501100F (561 series) share identical lens size (5mm T-1 3/4), mounting type (through-hole), and optical characteristics. Series designation reflects internal Dialight product categorization but does not affect form factor or electrical compatibility.
