Substitute Part Grouping Explanation

The Dialight 5502407F qualifies as a direct substitute for the 5502412F based on the following allowed substitution parameters:

Matching Parameters (Substitution Basis):

• Manufacturer: Dialight (same manufacturer)
• Series: 550 (same product line)
• Color: Red (identical optical output)
• Wavelength - Peak: 650nm (identical wavelength)
• Configuration: Single (identical electrical configuration)
• Current Rating: 10mA (identical current specification)
• Millicandela Rating: 7mcd (identical brightness output)
• Viewing Angle: 50° (identical viewing characteristics)
• Lens Type: Diffused (identical optical properties)
• Lens Style: Round with Domed Top (identical mechanical form)
• Lens Size: 5mm, T-1 3/4 (identical package dimensions)
• Mounting Type: Through Hole, Right Angle (identical mounting configuration)
• RoHS Status: ROHS3 Compliant (equivalent compliance)
• MSL Rating: 1 (Unlimited) (equivalent moisture sensitivity)

Differing Parameter:

• Voltage Rating: 5502412F operates at 2.1V; 5502407F operates at 2.2V

The 0.1V voltage differential falls within acceptable tolerance for LED circuit board indicator applications where forward voltage variation is a normal characteristic of semiconductor devices. Both parts maintain identical current and brightness specifications, confirming functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the Dialight 5502412F and 5502407F are Active product status components with full RoHS3 compliance and REACH unaffected designation, confirming ongoing manufacturer support and regulatory compliance for new designs and production applications.

The 5502412F (2.1V rating) and 5502407F (2.2V rating) are functionally equivalent for circuit board indicator applications. Selection between these parts depends on circuit design specifications:

• Use 5502412F where the design circuit provides 2.1V forward voltage bias
• Use 5502407F where the design circuit provides 2.2V forward voltage bias

Both parts deliver identical optical output (7mcd at 650nm), current consumption (10mA), and mechanical form factor (5mm T-1 3/4 through-hole right-angle mount). The voltage rating difference reflects normal forward voltage variation inherent to LED semiconductor manufacturing and does not affect brightness, color, or reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can I substitute 5502407F for 5502412F in my existing design?

A: Substitution is valid only if your circuit design accommodates the 2.2V forward voltage rating of the 5502407F. If your design is optimized for 2.1V operation, use the original 5502412F specification. Both parts are electrically and mechanically identical except for the 0.1V voltage differential.

Q: What is the significance of the voltage rating difference between these parts?

A: The 0.1V difference (2.1V vs. 2.2V) represents normal forward voltage variation in LED semiconductor manufacturing. Both parts operate at identical 10mA current and produce identical 7mcd brightness output. The voltage rating indicates the typical forward voltage drop when the LED conducts at rated current.

Q: Are both parts suitable for new production designs?

A: Yes. Both the 5502412F and 5502407F carry Active product status and full RoHS3 compliance, confirming manufacturer support for new designs and production applications.

Q: Do these parts have identical mechanical dimensions and mounting requirements?

A: Yes. Both parts feature identical 5mm T-1 3/4 lens size, round domed diffused lens style, and through-hole right-angle mounting configuration. No PCB layout or mechanical redesign is required when substituting between these parts.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly processes.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, confirming identical regulatory status for use in regulated markets and applications.
