Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Dialight 5500504 is based on strict electrical and mechanical parameter matching within the Dialight 550 series. The substitute part 5500504F maintains identical specifications across all critical parameters: red color (655nm peak wavelength), single configuration, 5V voltage rating, 13mA current requirement, 2mcd brightness, 60° viewing angle, diffused lens type, round domed top lens style, 5mm T-1 3/4 form factor, and through-hole mounting. The primary distinction is packaging format and product status transition from obsolete to active production.

Key Parameters for Substitution Compatibility:

• Color and wavelength (655nm red)
• Electrical ratings (5V, 13mA)
• Optical characteristics (2mcd, 60° viewing angle, diffused lens)
• Physical form factor (5mm T-1 3/4, round domed top)
• Mounting method (through-hole)
• Environmental compliance (MSL 1, REACH Unaffected)

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5500504F is the direct active production equivalent of the obsolete 5500504. Both parts are manufactured by Dialight within the 550 series and share identical electrical, optical, and mechanical specifications. The 5500504F is currently in active production status with confirmed inventory availability, whereas the 5500504 is classified as obsolete. The 5500504F carries ROHS3 compliance certification, providing enhanced environmental regulatory alignment for new designs and production runs. Both parts maintain REACH Unaffected status and EAR99 export classification. Selection of the 5500504F is appropriate for direct replacement in existing applications, new production designs, and maintenance scenarios where the original 5500504 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the 5500504F directly replace the 5500504 in existing circuit board designs?

A: Yes. The 5500504F is electrically and mechanically identical to the 5500504. Both parts operate at 5V with 13mA current draw, feature identical 655nm red wavelength output, 2mcd brightness, 60° viewing angle, and 5mm T-1 3/4 through-hole form factor. No circuit modifications are required.

Q: What is the difference between the 5500504 and 5500504F?

A: The primary differences are product status and packaging. The 5500504 is obsolete with standard packaging, while the 5500504F is in active production with bulk packaging. The 5500504F also carries ROHS3 compliance certification. All electrical and optical specifications are identical.

Q: Are there any compatibility concerns with the packaging difference?

A: No. The packaging difference (standard versus bulk) does not affect component performance or circuit board compatibility. The bulk packaging of the 5500504F is suitable for both prototype and production applications.

Q: Does the ROHS3 compliance of the 5500504F affect compatibility?

A: No. ROHS3 compliance is an environmental regulatory advantage that does not impact electrical or mechanical compatibility. The 5500504F can be used as a direct substitute in all applications where the 5500504 was previously used.

Q: What is the viewing angle specification and how does it affect placement?

A: Both parts have a 60° viewing angle with a diffused lens, providing wide-angle visibility. This specification determines the optimal mounting angle and viewing distance for the indicator in the application circuit board layout.

Q: Are moisture sensitivity considerations the same for both parts?

A: Yes. Both the 5500504 and 5500504F carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
