Key Parameters

Substitute Part Grouping Explanation

The identification of equivalent and substitute parts for the H2921R7GD is based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Configuration: 2 High dual-level LED arrangement
• Color: Green wavelength output
• Lens Type: Diffused optics
• Operating Voltage: 2.1V to 2.2V range
• Current Rating: 20mA to 30mA range
• Millicandela Rating: 4.3mcd to 7mcd range
• Viewing Angle: 104° to 125° range
• Moisture Sensitivity: MSL 1 (Unlimited)
• Export Classification: EAR99

The substitute part 5670122F from Dialight meets these core functional requirements while maintaining electrical and mechanical compatibility for circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

The 5670122F from Dialight serves as a functional substitute for the H2921R7GD in legacy circuit board indicator applications. The Dialight component offers the advantage of Active product status, ensuring continued supplier support and availability for future orders. Both components maintain identical Moisture Sensitivity Level (MSL 1) and operate within compatible voltage and current specifications suitable for typical circuit board indicator circuits.

The H2921R7GD remains the original specification for existing designs. The 5670122F provides equivalent performance characteristics for system maintenance and replacement applications where the original component becomes unavailable. Selection between these parts should be based on circuit board space constraints, current budget requirements, and brightness specifications for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the 5670122F directly replace the H2921R7GD in existing circuit board designs? Both components share identical configuration (2 High), color (Green x 2), lens type (Diffused), and Moisture Sensitivity Level (MSL 1). Operating voltages are compatible (2.1V vs 2.2V), and both include Right Angle mounting. The primary difference is reduced current draw (20mA vs 30mA) and lower brightness (4.3mcd vs 7mcd) for the Dialight part.

Q: What are the key differences between these two LED indicators? The H2921R7GD operates at higher current (30mA) and provides increased brightness (7mcd) with a wider viewing angle (125°). The 5670122F operates at lower current (20mA) with reduced brightness (4.3mcd) and slightly narrower viewing angle (104°). Peak wavelengths differ slightly (568nm vs 562nm), and the Dialight part includes a tinted lens in addition to diffused characteristics.

Q: Which part should be selected for new designs requiring the H2921R7GD specification? The 5670122F is the recommended selection for new designs, as the H2921R7GD is Obsolete. The Dialight component maintains Active product status and provides equivalent functional performance for circuit board indicator applications.

Q: Are there packaging differences between these components? The H2921R7GD is specified with dash (-) packaging notation. The 5670122F is supplied in Bulk packaging with Through Hole, Right Angle mounting configuration.

Q: What compliance standards apply to both components? Both parts carry EAR99 export classification and HTSUS code 8541.41.0000. The 5670122F includes ROHS3 Compliance and REACH Unaffected status certifications.
