LED Circuit Board Indicator 5912301002F Equivalent & Substitute Parts
Part Overview
The Dialight 5912301002F is a Surface Mount Right Angle LED Circuit Board Indicator featuring a 3mm T-1 round diffused lens with domed top. This component is classified as Obsolete, making identification of compatible alternatives essential for ongoing production and maintenance applications. The part operates at 2V with 10mA current consumption and delivers 4.8mcd luminous intensity with a 40° viewing angle. Due to its obsolete status, equivalent parts from the same manufacturer series provide continuity for designs requiring green LED indicators in compact surface mount configurations.

Substitute Part Grouping Explanation
Substitution eligibility for the 5912301002F is determined by the following critical parameters:
Mandatory Compatibility Criteria:
- Manufacturer: Dialight (same manufacturer ensures design compatibility within Series 591)
- Color: Green (572nm wavelength peak)
- Configuration: Single LED
- Voltage Rating: 2V (electrical compatibility with existing circuit designs)
- Mounting Type: Surface Mount, Right Angle (PCB layout compatibility)
- Viewing Angle: 40° (optical performance consistency)
- Lens Style: Round with Domed Top (mechanical fit and appearance)
- RoHS Status: ROHS3 Compliant (regulatory requirement)
- Moisture Sensitivity Level: 2 (1 Year) (handling and storage compatibility)
Parameters Permitting Variation:
- Current: 10mA (main part) to 20mA (substitute) — acceptable when circuit design accommodates higher current draw
- Millicandela Rating: 4.8mcd (main part) to 15mcd (substitute) — acceptable when increased brightness does not conflict with application requirements
- Lens Size: 3mm T-1 (main part) to 2.85mm Dia (substitute) — acceptable for applications where minor dimensional variation is tolerable
The substitute part 5912301002NF maintains electrical and mechanical compatibility while offering enhanced luminous intensity and current capacity within the same product series.

Engineering Selection Recommendations
The 5912301002NF is an active production equivalent for the obsolete 5912301002F. Both components maintain identical voltage ratings, mounting configurations, and regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected). The substitute part offers increased current capacity (20mA versus 10mA) and higher luminous intensity (15mcd versus 4.8mcd) while preserving the same optical characteristics and mechanical form factor. Selection of the 5912301002NF is appropriate for applications where the original part is no longer available and circuit design can accommodate the higher current specification.
Frequently Asked Questions (FAQ)
Q: Can the 5912301002NF directly replace the 5912301002F in existing designs?
A: Direct replacement is possible when the circuit design accommodates 20mA current draw. The substitute maintains identical voltage rating (2V), mounting type (Surface Mount, Right Angle), and optical viewing angle (40°). Verify that the power supply and current-limiting resistor network can support the increased current specification.
Q: What is the significance of the lens size difference between 3mm T-1 and 2.85mm Dia?
A: The 2.85mm diameter lens of the substitute part represents a minor dimensional variation. This difference is acceptable for applications where the LED indicator fits within a standard 3mm mounting aperture with standard tolerances. Confirm mechanical fit within your specific PCB layout and enclosure design.
Q: Are there any compliance or regulatory differences between these parts?
A: Both parts maintain identical regulatory status: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 2 (1 Year). No compliance barriers exist for substitution.
Q: Why does the substitute part have higher millicandela rating?
A: The 5912301002NF delivers 15mcd compared to 4.8mcd in the original part. This increased brightness results from the higher current specification (20mA versus 10mA). Verify that increased luminous intensity does not create visual conflicts in your application (such as excessive brightness in low-light environments).
Q: What packaging format is available for the substitute part?
A: The 5912301002NF is supplied in Strip packaging, compared to the original part's standard packaging. Confirm that Strip packaging meets your assembly and handling requirements.
