Equivalent & Substitute Parts: VCC 161-10PK

Part Overview

The VCC 161-10PK is an incandescent lamp designed for indicator and signal applications requiring a 14V power supply. This component features a clear lens with a round domed top configuration and utilizes a wedge-style lead for direct insertion into compatible sockets. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain the same electrical and mechanical specifications. Active substitute inventory is available through equivalent part sourcing.

Substitute Part Grouping Explanation

The CEC Industries 161 lamp qualifies as a direct substitute for the VCC 161-10PK based on alignment across all critical electrical and mechanical parameters. Substitution eligibility is determined by the following matched specifications:

Electrical Parameters:

• Voltage Rating: 14V (identical)
• MSCP: 1 (identical)

Mechanical Parameters:

• Lens Size: T-3.25 / RT-3 1/4 (equivalent designations)
• Lead Style: Wedge (identical)
• Lens Configuration: Round with Domed Top (identical)

Compliance Parameters:

• RoHS Compliance: Both parts meet RoHS requirements
• ECCN Classification: EAR99 (identical)

The CEC Industries 161 is supplied in a box of 10 units and maintains active product status with 2,200 pieces in stock, providing immediate availability for applications currently using the discontinued VCC 161-10PK.

Parameter Comparison

Engineering Selection Recommendations

The CEC Industries 161 lamp is the direct equivalent substitute for the VCC 161-10PK. Both components satisfy identical electrical requirements (14V, 1 MSCP) and mechanical specifications (T-3.25/RT-3 1/4 lens size, wedge lead configuration, round domed top).

The CEC Industries 161 is recommended for new designs and replacement applications due to its active product status and superior inventory availability (2,200 units versus 865 units for the discontinued VCC part). Both components maintain RoHS compliance and EAR99 ECCN classification, ensuring regulatory consistency in applications requiring these certifications.

The wedge lead base (W2.1X9.5D) on the CEC Industries 161 is mechanically and electrically compatible with sockets designed for the VCC 161-10PK, enabling direct substitution without circuit modification or socket redesign.

Frequently Asked Questions (FAQ)

Q: Can the CEC Industries 161 be used as a direct replacement for the VCC 161-10PK without circuit modifications?

A: Yes. Both lamps operate at 14V with identical MSCP output (1), lens size (T-3.25/RT-3 1/4), and wedge lead configuration. The mechanical and electrical interfaces are compatible, permitting direct substitution in existing sockets and circuits.

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

A: RT-3 1/4 and T-3.25 are equivalent designations for the same lens diameter. RT indicates "Round Top" while T indicates the standard lens type. Both refer to a 3.25-inch diameter lens. These designations are interchangeable in technical specifications.

Q: Are there packaging differences between the VCC 161-10PK and CEC Industries 161?

A: The VCC 161-10PK is supplied as a 10-pack (161-10PK designation). The CEC Industries 161 is supplied in a box of 10 units. Both provide the same quantity per package, ensuring equivalent unit counts for inventory planning.

Q: Do both lamps meet the same compliance standards?

A: Both the VCC 161-10PK and CEC Industries 161 are RoHS compliant and classified as EAR99 for export control purposes. The VCC part carries ROHS3 certification while the CEC part carries standard RoHS certification; both meet current regulatory requirements.

Q: What is the wedge base specification W2.1X9.5D?

A: W2.1X9.5D specifies the wedge lead dimensions: W2.1 indicates a 2.1mm lead width, and 9.5D indicates a 9.5mm lead length with a domed configuration. This base type is the standard wedge configuration for T-3.25 lamps and is compatible with corresponding socket designs.
