Key Parameters

Substitute Part Grouping Explanation

Substitution for the Dialight 5210313 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: 28V (exact match required)
• Lamp Type: Incandescent (functional category)
• Lens Color: Clear (optical specification)
• Lens Style: Round with Domed Top (mechanical form factor)
• Lens Size: RT-3 1/4 (dimensional specification)
• Lead Style: Miniature Bayonet (electrical connection interface)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The Visual Communications Company (VCC) CM313 meets all these parameters and is classified as a direct substitute. Both parts share identical electrical, optical, and mechanical specifications, with the primary distinction being manufacturer origin and current product status.

Parameter Comparison

Engineering Selection Recommendations

The VCC CM313 is a direct functional equivalent to the Dialight 5210313 based on matching electrical specifications (28V), optical properties (clear color), mechanical form factor (RT-3 1/4 round domed top), and connection interface (miniature bayonet). Both components maintain ROHS3 compliance and identical moisture sensitivity ratings.

Selection between these parts should be based on availability and supply chain requirements. The Dialight 5210313 is discontinued at DiGi Electronics, while the VCC CM313 is marked as not for new designs but remains in stock. For replacement and maintenance applications, the VCC CM313 provides electrical and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the VCC CM313 directly replace the Dialight 5210313 in existing applications?

A: Yes. Both lamps share identical voltage rating (28V), lens specifications (RT-3 1/4 clear round domed top), and miniature bayonet lead style. No circuit or mechanical modifications are required for substitution.

Q: What is the significance of the MSCP rating listed for the VCC CM313?

A: MSCP (Mean Spherical Candle Power) of 4.6 indicates the luminous intensity output of the lamp. This specification is provided for the VCC CM313 but not documented for the Dialight 5210313. Both lamps are functionally equivalent for illumination applications.

Q: Are both parts compliant with current regulatory standards?

A: Both the Dialight 5210313 and VCC CM313 are ROHS3 compliant and REACH unaffected. They meet current environmental and hazardous substance restrictions for industrial applications.

Q: Why is the Dialight 5210313 discontinued while the VCC CM313 is marked "Not For New Designs"?

A: Discontinuation reflects manufacturer supply decisions and market demand. The VCC CM313 designation indicates it is available for replacement and maintenance purposes but not recommended for new product development. For existing systems requiring the Dialight 5210313, the VCC CM313 remains a compatible alternative.

Q: What packaging considerations apply to these lamps?

A: The Dialight 5210313 is supplied in standard packaging, while the VCC CM313 is supplied in bag packaging. Both are suitable for component-level installation in miniature bayonet sockets.
