Key Parameters

Substitute Part Grouping Explanation

The Dialight 5912301007NF serves as a manufacturer-recommended substitute for the 5912201007F. Substitution compatibility is determined by the following critical parameters:

• Color and wavelength matching (Green, 572nm peak)
• Voltage rating compatibility (2V)
• Configuration (Single LED)
• Mounting type (Surface Mount, Right Angle)
• Lens style (Round with Domed Top)
• Compliance certifications (ROHS3, REACH Unaffected)

The substitute part maintains these core parameters while operating at a reduced current rating (20mA versus 30mA) and offering a slightly higher brightness output (15mcd versus 12mcd) in a marginally smaller package (2.85mm versus 3.00mm lens diameter).

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5912301007NF is the manufacturer-recommended substitute for the obsolete 5912201007F. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system replacements.

The substitute part operates at a lower current requirement (20mA versus 30mA), reducing power consumption in the application circuit. The increased brightness output (15mcd versus 12mcd) at lower current provides improved visibility with reduced thermal load. The 0.15mm reduction in lens diameter (2.85mm versus 3.00mm) represents a minor dimensional change that requires verification against mechanical mounting constraints in the target application.

Both components share identical voltage ratings, viewing angles, and mounting configurations, supporting direct electrical substitution with minimal circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the 5912301007NF directly replace the 5912201007F in existing designs?

A: Electrical substitution is supported due to matching voltage ratings, configuration, and mounting type. Mechanical verification is required to confirm that the 2.85mm lens diameter accommodates existing panel cutouts and mounting fixtures designed for the 3.00mm original component.

Q: What is the impact of the 10mA current reduction in the substitute part?

A: The substitute part operates at 20mA versus the original 30mA rating. Circuit current-limiting resistors must be recalculated based on the new current specification to maintain proper LED operation and brightness levels.

Q: Are both parts suitable for new production designs?

A: The 5912301007NF is the active product and is recommended for new designs. The 5912201007F is obsolete and should not be specified for new production.

Q: Do both parts meet the same compliance requirements?

A: Both components are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards for industrial and commercial applications.

Q: What is the significance of the brightness increase in the substitute part?

A: The substitute delivers 15mcd versus 12mcd at a lower current rating, indicating improved LED efficiency. This allows for equivalent or enhanced visibility with reduced power consumption.
