Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCC 757-10PK is determined by the following critical parameters:

Primary Compatibility Criteria:

• Voltage Rating: 28V (exact match required)
• Lens Size: RT-3 1/4 or T-3.25 (equivalent designations)
• Lead Style: Bayonet base configuration
• Lamp Type: Incandescent

The CEC Industries 1829 qualifies as a substitute based on matching voltage rating (28V), equivalent lens size designation (T-3.25 / BA9S), and bayonet base configuration. Both parts operate at 28V with compatible bayonet mounting interfaces suitable for legacy 28V lamp sockets.

Parameter Comparison

Engineering Selection Recommendations

The CEC Industries 1829 serves as an active substitute for the VCC 757-10PK in 28V lamp applications. The primary advantage of the 1829 is its Active product status, ensuring continued availability and supply chain reliability compared to the legacy VCC part marked Not For New Designs.

Both parts share identical voltage ratings (28V) and compatible bayonet base configurations. The CEC Industries 1829 operates at higher luminous intensity (1 MSCP versus 0.62 MSCP), which may affect brightness output in the application. Compliance certifications (ROHS3, REACH, ECCN EAR99) are confirmed for the VCC 757-10PK; equivalent compliance documentation should be verified for the CEC Industries 1829 prior to procurement.

Frequently Asked Questions (FAQ)

Q: Can the CEC Industries 1829 directly replace the VCC 757-10PK in existing fixtures?

A: Both parts operate at 28V with bayonet base configurations compatible with standard 28V lamp sockets. Physical fit and electrical compatibility are established through matching voltage and base type. The higher MSCP rating (1 versus 0.62) will produce increased brightness.

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

A: RT-3 1/4 and T-3.25 are equivalent designations for the same lamp envelope size. RT indicates "Round Top" while T indicates the tubular diameter in eighths of an inch (3.25 = 26/8 inches). Both refer to the same physical dimensions.

Q: Are there packaging differences between these parts?

A: The VCC 757-10PK is supplied in a Bag (10-pack), while the CEC Industries 1829 is supplied in a Box of 10. Packaging format does not affect electrical or mechanical compatibility.

Q: What should be verified before substituting these parts?

A: Confirm the application socket accepts standard bayonet bases, verify 28V supply voltage, and assess whether the increased brightness output (1 MSCP versus 0.62 MSCP) is acceptable for the intended application.

Q: Is the CEC Industries 1829 suitable for new designs?

A: The CEC Industries 1829 carries Active product status, making it suitable for new designs. The VCC 757-10PK is marked Not For New Designs and should be replaced with active alternatives in new applications.
