Equivalent & Substitute Parts: 194--10PK

Part Overview

The 194--10PK is an incandescent lamp manufactured by Visual Communications Company (VCC), designed as a clear, round domed-top indicator light with a 14V voltage rating and RT-3 1/4 wedge base configuration. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing maintenance, repair, and system support applications. The part delivers 2 MSCP (Mean Spherical Candle Power) output and is packaged as a 10-piece unit. Due to its obsolete status, sourcing direct replacements requires evaluation of active-production alternatives that maintain electrical and mechanical compatibility.

Engineering Selection Recommendations

Primary Substitute: CEC Industries 194

The CEC Industries 194 incandescent lamp is the appropriate substitute for the obsolete VCC 194--10PK based on:

Electrical Equivalence: Identical 14V voltage rating and 2 MSCP light output ensure functional performance in the original application circuit.
Mechanical Compatibility: T-3.25 lens size and wedge base configuration provide direct socket compatibility with systems designed for RT-3 1/4 wedge lamps.
Regulatory Compliance: Both parts meet RoHS requirements, satisfying environmental and safety standards for electronic component use.
Availability: The CEC Industries part maintains active production status, ensuring reliable long-term sourcing compared to the obsolete VCC original.
Packaging Alignment: Both parts are supplied in 10-piece quantities, maintaining consistency with original procurement specifications.

Frequently Asked Questions (FAQ)

Q: Can the CEC Industries 194 be used as a direct replacement for the VCC 194--10PK?

A: Yes. Both parts share identical voltage ratings (14V), light output (2 MSCP), incandescent technology, clear lens color, and wedge base configuration. The T-3.25 and RT-3 1/4 designations refer to the same physical lens dimension. Socket compatibility is maintained.

Q: What is the difference between RT-3 1/4 and T-3.25 lens size designations?

A: RT-3 1/4 (round top, 3 1/4 inches) and T-3.25 (tubular, 3.25 inches) are equivalent designations for the same physical lamp dimension. Both refer to a 3.25-inch diameter lens. The different naming conventions reflect manufacturer nomenclature variations.

Q: Are there any compliance differences between the VCC and CEC parts?

A: Both parts are RoHS compliant. The VCC part carries ROHS3 Compliant status, while the CEC part carries RoHS Compliant status. Both meet current regulatory requirements for electronic component use.

Q: Does the CEC Industries 194 come in the same 10-piece packaging as the original?

A: Yes. The CEC Industries 194 is supplied in a box of 10 units, matching the original VCC 194--10PK packaging quantity.

Q: What is the wedge base specification for the CEC Industries 194?

A: The CEC Industries 194 uses a W2.1X9.5D wedge base, which is the standard wedge base configuration for T-3.25 lamps and is compatible with RT-3 1/4 wedge sockets.

Q: Is the CEC Industries 194 currently in production?

A: Yes. The CEC Industries 194 maintains active product status, ensuring availability for new orders and ongoing supply.
