Equivalent & Substitute Parts Reference: 1815-10PK

Part Overview

The 1815-10PK is an incandescent lamp manufactured by Visual Communications Company (VCC), designed as a clear round lamp with domed top and miniature bayonet lead style. This component is rated for 14V operation with a mean spherical candle power (MSCP) of 1.4. The product is discontinued at DiGi Electronics, necessitating identification of alternative components for ongoing applications requiring similar electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the 1815-10PK is constrained by the limited technical overlap between the main part and the identified substitute. The primary substitute listed is part number 1815 from Adafruit Industries LLC.

Substitution Logic:

The substitute part 1815 shares the following parameters with the main part:

• RoHS3 Compliance status
• ECCN classification (EAR99)
• General component category within optoelectronic/indicator devices

Critical Parameter Differences:

The substitute part 1815 is fundamentally different in technology type, electrical characteristics, and mechanical form factor:

• Main part: Incandescent lamp technology, 14V operation
• Substitute: LED circuit board indicator, 3.2V operation, bar configuration with 10 segments
• Lead style: Main part uses miniature bayonet; substitute uses through-hole DIP mounting
• Lens configuration: Main part has round domed top; substitute has rectangle with flat top

Parameter Comparison

Engineering Selection Recommendations

Direct substitution of part 1815 for 1815-10PK is not supported based on provided technical parameters. The substitute part operates at a fundamentally different voltage level (3.2V versus 14V), uses different lead technology (through-hole DIP versus miniature bayonet), and employs LED technology instead of incandescent technology.

Both parts maintain ROHS3 compliance and EAR99 ECCN classification. The main part is discontinued; however, the substitute part does not satisfy the electrical and mechanical requirements specified for the original 1815-10PK application.

For applications requiring 14V incandescent lamp operation with miniature bayonet leads and round domed lens configuration, alternative sources for the original 1815-10PK or equivalent incandescent lamps with matching specifications should be pursued.

Frequently Asked Questions (FAQ)

Q: Can part 1815 directly replace 1815-10PK in existing applications?

A: No. The substitute part 1815 operates at 3.2V and uses through-hole DIP mounting, whereas the main part 1815-10PK requires 14V operation with miniature bayonet leads. Circuit redesign would be necessary.

Q: What are the key differences in lead style between these parts?

A: The 1815-10PK uses miniature bayonet leads for socket-based connection. The substitute part 1815 uses through-hole DIP leads for printed circuit board insertion. These are mechanically incompatible.

Q: Are both parts RoHS compliant?

A: Yes. Both 1815-10PK and 1815 maintain ROHS3 compliance status.

Q: Why is the substitute part listed if it cannot replace the main part?

A: The substitute relationship is based on partial parameter alignment (RoHS status, ECCN classification) and shared manufacturer reference numbering. However, electrical and mechanical parameters do not support functional substitution.

Q: What should be done if 1815-10PK is no longer available?

A: Identify alternative incandescent lamps with matching specifications: 14V voltage rating, miniature bayonet lead style, round domed lens configuration, and RT-3 1/4 lens size. Consult with component distributors specializing in discontinued lighting components.
