Substitute Part Grouping Explanation
Substitution of the Dialight 5912101007F is determined by the following critical parameters:
- Mounting Type: Surface Mount, Right Angle configuration must be maintained for PCB compatibility
- Color & Wavelength: Red spectrum (645nm peak) ensures visual consistency in indicator applications
- Configuration: Single LED configuration for direct functional replacement
- Lens Style & Size: Round domed lens geometry affects optical performance and mechanical fit
- Electrical Ratings: Voltage (1.75V) and current (10mA) determine circuit compatibility and power requirements
- Compliance: RoHS3 and REACH compliance ensure regulatory alignment with current manufacturing standards
The Dialight 5912101007NF qualifies as a substitute based on shared mounting type, color, configuration, lens style, and compliance certifications. Variations in lens size (2.85mm vs. 3mm), electrical ratings (1.85V/20mA vs. 1.75V/10mA), and brightness output (34mcd vs. 18mcd) represent design trade-offs that must be evaluated within specific application contexts.

Engineering Selection Recommendations
The Dialight 5912101007NF is an active production substitute for the obsolete 5912101007F. Both components maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected) and moisture sensitivity ratings (MSL 2, 1 Year), ensuring regulatory and environmental compatibility.
The substitute part differs in electrical and optical specifications: the 5912101007NF operates at 1.85V with 20mA current and delivers 34mcd brightness, compared to the original 1.75V/10mA/18mcd configuration. The lens size is reduced from 3mm to 2.85mm diameter. These differences require circuit-level evaluation to determine suitability for specific applications. The substitute's higher brightness and current rating may necessitate circuit modifications to maintain original performance characteristics.
Frequently Asked Questions (FAQ)
Q: Can the Dialight 5912101007NF directly replace the 5912101007F without circuit modifications?
A: Direct replacement depends on application requirements. Both parts share identical mounting type (Surface Mount, Right Angle), color (Red), configuration (Single), lens style (Round with Domed Top), and compliance certifications. However, the substitute operates at different electrical ratings (1.85V/20mA vs. 1.75V/10mA) and delivers higher brightness (34mcd vs. 18mcd). Circuit evaluation is necessary to confirm compatibility.
Q: What are the key differences between these two parts?
A: The primary differences are lens size (2.85mm vs. 3mm), voltage rating (1.85V vs. 1.75V), current rating (20mA vs. 10mA), wavelength (655nm vs. 645nm), and brightness output (34mcd vs. 18mcd). The substitute part is in active production status, whereas the original is obsolete.
Q: Are both parts RoHS and REACH compliant?
A: Yes. Both the 5912101007F and 5912101007NF are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and use.
Q: What is the packaging difference between these parts?
A: The main part (5912101007F) is listed with standard packaging, while the substitute (5912101007NF) is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount production.
Q: How do the viewing angles compare?
A: Both parts maintain an identical 40° viewing angle, ensuring consistent optical performance in indicator applications.
