Equivalent & Substitute Parts Reference: VCC 8918

Part Overview

The VCC 8918 is an incandescent lamp classified as an obsolete product. This component is a clear incandescent lamp rated at 14V with a round domed top lens, RT-1 3/4 midget flange configuration, and 0.5 MSCP output. Due to its obsolete status, identification of equivalent and substitute parts is necessary for system maintenance, repair, and component replacement in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the VCC 8918 incandescent lamp is constrained by the following critical parameters:

Voltage Rating: The substitute must operate at 14V to ensure compatibility with the original circuit design.

Lens Configuration: The round domed top lens style and RT-1 3/4 size determine mechanical fit and optical characteristics.

Lead Style: The midget flange lead configuration is essential for proper mounting and electrical connection.

Light Output: The 0.5 MSCP specification defines the luminous intensity requirement.

Compliance Requirements: RoHS3 compliance and MSL rating must be maintained for regulatory and environmental standards.

The substitute part identified (Keystone Electronics 8918) shares the same part number designation but represents a different product category (LED standoff spacer). This indicates a cross-reference designation rather than a functional equivalent. Direct functional substitutes for the VCC 8918 incandescent lamp must match all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The VCC 8918 is classified as obsolete. When replacement is required, the following selection criteria apply:

Functional Equivalence: A true substitute must be an incandescent lamp with identical electrical specifications (14V rating), mechanical configuration (round domed top, RT-1 3/4 lens, midget flange lead), and optical output (0.5 MSCP).

Compliance Verification: Any substitute must maintain ROHS3 compliance and MSL rating 1 status to satisfy regulatory requirements and environmental standards.

Cross-Reference Clarification: The Keystone Electronics part number 8918 listed in the substitute field is a different product category (LED standoff spacer) and is not a functional equivalent for the incandescent lamp application.

Inventory Consideration: Current stock of VCC 8918 (725 pcs) is available as original equipment. Substitution should only be pursued when original stock is exhausted or when system redesign permits alternative lighting technologies.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 8918 replace the VCC 8918 incandescent lamp?

A: No. Despite sharing the same part number designation, the Keystone Electronics 8918 is an LED standoff spacer, not an incandescent lamp. These are functionally incompatible products serving different applications.

Q: What parameters must a substitute incandescent lamp match?

A: A substitute must match all of the following: 14V voltage rating, clear color, round domed top lens style, RT-1 3/4 lens size, midget flange lead configuration, and 0.5 MSCP light output.

Q: Is the VCC 8918 still available for purchase?

A: The VCC 8918 is classified as obsolete. However, 725 pieces are currently in stock as new original inventory.

Q: What compliance standards apply to substitute parts?

A: Substitute parts must maintain ROHS3 compliance and MSL rating 1 (unlimited moisture sensitivity level) to match the original specification.

Q: Can LED lamps substitute for this incandescent lamp?

A: LED substitution requires verification of voltage compatibility, light output equivalence, and mechanical fit. The provided data does not include LED lamp specifications that meet the VCC 8918 parameters.
