Key Parameters

Substitute Part Grouping Explanation

The Dialight 5571303203F qualifies as a direct substitute based on the following critical parameters:

• Manufacturer continuity: Both parts are manufactured by Dialight within the same 557 series
• Voltage compatibility: Both rated for 12V operation
• Lamp color match: Both produce yellow illumination
• Mechanical compatibility: Both feature round panel cutout geometry suitable for 0.69" (17.53mm) diameter openings
• Ingress protection: Both maintain water-resistant construction for environmental protection

The 5571303203F represents an active product status alternative, providing continued availability and modern compliance certifications while maintaining functional equivalence with the obsolete 5571303203.

Parameter Comparison

Engineering Selection Recommendations

The 5571303203F is the designated substitute for the obsolete 5571303203 based on manufacturer continuity within the Dialight 557 series and matching voltage and color specifications. The substitute part carries ROHS3 compliance, representing an upgrade from the non-compliant status of the original part.

For applications requiring RoHS non-compliant components, the original 5571303203 remains available in current inventory (985 units). For new designs or systems requiring modern compliance certifications, the 5571303203F (1012 units in stock) provides an active product alternative with equivalent functional parameters.

Both parts are classified under HTSUS code 8541.41.0000 and carry EAR99 ECCN designation with REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 5571303203F directly replace the 5571303203 in existing equipment?

A: Yes. Both parts share identical voltage (12V), lamp color (yellow), and mechanical mounting specifications (round 0.69" panel cutout). The 5571303203F is the active product continuation of the obsolete 5571303203 within the Dialight 557 series.

Q: What is the primary difference between these two parts?

A: The 5571303203F carries ROHS3 compliance, while the 5571303203 is RoHS non-compliant. Both maintain equivalent electrical and mechanical functionality for 12V yellow LED panel indication applications.

Q: Are there packaging differences between the main part and substitute?

A: Both parts are supplied in bulk packaging. The 5571303203F is the current production variant with modern compliance certifications.

Q: What parameters determine substitutability for this LED panel indicator category?

A: Voltage rating, lamp color, panel cutout diameter, and mechanical mounting style are the primary parameters governing substitution. Both parts match on all critical parameters: 12V operation, yellow color, and round 0.69" (17.53mm) panel cutout geometry.

Q: Is the current rating specification critical for substitution?

A: The 5571303203 specifies 25mA maximum current. While the 5571303203F does not provide explicit current rating in available documentation, both parts operate within the same voltage class and series, indicating functional equivalence for standard 12V panel indicator applications.
