LED Replacement T-3 1/4 Bayonet 1835LS3-A-CA Equivalent & Substitute Parts

Part Overview

The 1835LS3-A-CA is an LED lamp replacement unit manufactured by Visual Communications Company (VCC) designed for T-3 1/4 bayonet base applications. This component operates at 240V and produces amber-colored illumination for general purpose lighting installations. The part is currently in active product status with 699 units available in stock. Substitute parts are identified when equivalent functional performance can be achieved through alternative voltage ratings while maintaining identical mechanical and optical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1835LS3-A-CA is determined by the following parameters that must remain constant across all equivalent parts:

Fixed Parameters (Must Match):

• Size / Dimension: T - 3 1/4
• Base Type: Bayonet
• Color: Amber
• Configuration: Single
• Applications: General Purpose Lighting
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameter (Allows Substitution):

• Voltage - Forward (Vf) (Typ): Different voltage ratings are acceptable when the mechanical and optical characteristics remain identical

The 1835LS2-A-CA qualifies as a parametric equivalent because it maintains all fixed parameters while operating at a different voltage rating (48V instead of 240V). Both parts share identical form factor, base type, color output, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 1835LS3-A-CA and 1835LS2-A-CA maintain active product status with full regulatory compliance under ROHS3 and REACH standards. Selection between these parts is determined by the voltage requirement of the target application circuit. The 1835LS3-A-CA operates at 240V and is suitable for high-voltage general purpose lighting systems. The 1835LS2-A-CA operates at 48V and is suitable for low-voltage general purpose lighting systems. Both parts are manufactured by VCC and share identical mechanical form factors (T-3 1/4 bayonet base) and optical characteristics (amber color output). Component selection must align with the system voltage specification to ensure proper operation and safety compliance.

Frequently Asked Questions (FAQ)

Q: Can the 1835LS2-A-CA replace the 1835LS3-A-CA in any application?

A: Mechanical and optical compatibility exists between these parts. However, voltage compatibility must be verified. The 1835LS2-A-CA operates at 48V while the 1835LS3-A-CA operates at 240V. Direct substitution is only valid when the application circuit voltage matches the substitute part's voltage rating.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching size (T-3 1/4), base type (bayonet), color (amber), configuration (single), and application category (general purpose lighting). Voltage rating is application-dependent and does not prevent substitution when the circuit voltage is compatible.

Q: Are both parts compliant with environmental and safety standards?

A: Both the 1835LS3-A-CA and 1835LS2-A-CA are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulatory requirements.

Q: What is the difference in inventory availability?

A: The 1835LS3-A-CA has 699 units in stock, while the 1835LS2-A-CA has 1074 units in stock. Both are available as new original components in bulk packaging.

Q: Can these parts be used interchangeably in the same fixture?

A: Physical interchangeability exists due to identical form factor and bayonet base design. Electrical interchangeability depends on the fixture's voltage supply. The fixture must operate at either 240V (for 1835LS3-A-CA) or 48V (for 1835LS2-A-CA) to ensure proper component operation.
