Dialight 5611301070 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5611301070 is a 2.00mm diameter green LED circuit board indicator designed for through-hole mounting applications. This component features a single green diffused lens with a round flat-top design, operating at 1.8V with 2mA current consumption and 1.8 millicandela brightness output.

The 5611301070 is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5611301070 is determined by the following critical parameters:

• Electrical Compatibility: Voltage rating (1.8V), current consumption (2mA), and wavelength (565nm green) must remain constant
• Optical Performance: Millicandela rating (1.8mcd) and viewing angle (50°) define brightness and visibility characteristics
• Mechanical Compatibility: Mounting type (through hole) and lens configuration (diffused) must be maintained
• Configuration: Single LED configuration required

The substitute part 5611301070F maintains all critical electrical and optical parameters while introducing a physical form factor change: the lens size increases from 2.00mm to 5mm (T-1 3/4) with a domed top lens style replacing the flat-top design. This change accommodates different PCB layout requirements while preserving functional performance.

Parameter Comparison

Engineering Selection Recommendations

The 5611301070F serves as the active production substitute for the obsolete 5611301070. Both components share identical electrical specifications (1.8V, 2mA, 565nm wavelength) and optical performance (1.8mcd, 50° viewing angle).

The primary design consideration is the physical form factor change: the 5611301070F features a larger 5mm lens diameter with domed top styling compared to the 2.00mm flat-top design of the original part. This change requires PCB layout modification to accommodate the increased component footprint.

The 5611301070F provides improved regulatory compliance, meeting ROHS3 requirements, whereas the original part is RoHS non-compliant. Both components maintain MSL 1 (unlimited) moisture sensitivity rating and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 5611301070F be used as a direct drop-in replacement for the 5611301070?

A: Electrical and optical performance are identical. However, the 5mm lens diameter of the 5611301070F requires PCB layout modification compared to the 2.00mm lens of the original part. Physical board space and mounting hole positioning must be verified before implementation.

Q: What are the key differences between these parts?

A: The primary differences are lens size (2.00mm vs. 5mm), lens style (flat top vs. domed top), and RoHS compliance status (non-compliant vs. ROHS3 compliant). Electrical specifications, brightness output, and viewing angle remain unchanged.

Q: Are there any compliance considerations when switching to the 5611301070F?

A: The 5611301070F meets ROHS3 compliance requirements, whereas the original 5611301070 is RoHS non-compliant. If your application requires RoHS compliance, the 5611301070F is the appropriate selection.

Q: What is the impact of the lens size change on circuit board design?

A: The increase from 2.00mm to 5mm diameter requires verification of available PCB space, mounting hole spacing, and clearance from adjacent components. The domed top lens style may also affect viewing angle characteristics in specific mounting orientations.

Q: Are the voltage and current specifications identical?

A: Yes. Both the 5611301070 and 5611301070F operate at 1.8V with 2mA current consumption, ensuring compatibility with existing circuit designs from an electrical standpoint.
