Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCC 344 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage Rating: 10V
• Lead Style: Midget Flange
• Lens Size Category: RT-1 3/4 / T-1.75 equivalent dimensions
• Type: Incandescent lamp

Allowable Variation Parameters:

• MSCP (Mean Spherical Candle Power): Substitutes may have different output values
• Product Status: Active substitutes are acceptable for obsolete parts
• Manufacturer: Different manufacturers permitted if electrical and mechanical specifications align

The CEC Industries 367 qualifies as a direct substitute based on matching voltage rating (10V), midget flange base configuration, equivalent T-1.75 lens size, and incandescent lamp type.

Parameter Comparison

Engineering Selection Recommendations

For VCC 344 Replacement:

The CEC Industries 367 is a qualified substitute for the obsolete VCC 344. Both components share identical voltage ratings (10V) and midget flange base configurations, which are the primary mechanical and electrical compatibility criteria for incandescent lamp substitution.

Considerations:

The CEC Industries 367 operates at a higher MSCP value (0.08 versus 0.002), indicating increased luminous intensity. This difference must be evaluated within the context of the application circuit to ensure compatibility with existing brightness requirements and current-limiting design parameters.

Both parts carry EAR99 ECCN classification, confirming equivalent export control status.

VCC 344: 990 units available as new original stock CEC Industries 367: 785 units available as new original stock

Frequently Asked Questions (FAQ)

Q: Can the CEC Industries 367 be used as a direct replacement for the VCC 344?

A: Yes. Both components share the same 10V voltage rating and midget flange base configuration. The lens size designations (RT-1 3/4 and T-1.75) are equivalent in physical dimensions for this lamp category.

Q: What is the significance of the MSCP difference between these parts?

A: MSCP (Mean Spherical Candle Power) measures luminous intensity. The CEC Industries 367 produces 0.08 MSCP compared to 0.002 MSCP for the VCC 344. This 40-fold increase in brightness output must be evaluated against the application's optical and thermal design requirements.

Q: Are there packaging differences between these parts?

A: The CEC Industries 367 is supplied in boxes of 10 units. The VCC 344 packaging configuration is not specified in the available data.

Q: Do both parts meet RoHS compliance requirements?

A: The VCC 344 is ROHS3 compliant. RoHS status for the CEC Industries 367 is not specified in the available documentation.

Q: What is the base type for the CEC Industries 367?

A: The CEC Industries 367 uses an SX6S midget flange base, which is mechanically compatible with the VCC 344 midget flange configuration.
