LED Replacement T-3 1/4 Bayonet Red 1815L-R-CR Equivalent & Substitute Parts

Part Overview

The 1815L-R-CR is a red LED lamp replacement designed for miniature bayonet (BA9S) applications operating at 12V AC/DC. This component functions as a direct replacement for multiple miniature bayonet lamp types in general purpose lighting applications. The part is classified as obsolete, making identification of active equivalent substitutes essential for procurement and design continuity. The substitute part 1815LS-R-CR provides functional equivalence while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the 1815L-R-CR and 1815LS-R-CR is determined by alignment across the following critical parameters:

• Base Type: Both parts use Miniature Bayonet (BA9S) connector, ensuring mechanical compatibility
• Size / Dimension: Both are T - 3 1/4 form factor
• Voltage - Forward (Vf): Both operate at 12V AC/DC
• Color: Both emit red light
• Configuration: Both are single-element configurations
• Applications: Both serve general purpose lighting functions
• RoHS Compliance: Both meet ROHS3 requirements

The 1815LS-R-CR maintains identical electrical and mechanical specifications while offering active product status and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The 1815LS-R-CR is the appropriate selection for new designs and ongoing procurement requirements. This part maintains full electrical and mechanical compatibility with the obsolete 1815L-R-CR while offering active product status from the manufacturer. The active status ensures continued availability, supply chain stability, and compliance with current regulatory standards. Both parts carry ROHS3 compliance certification, meeting environmental and material restriction requirements. The 1815LS-R-CR is available in bulk packaging, supporting production-scale requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1815LS-R-CR directly replace the 1815L-R-CR in existing applications?

A: Yes. Both parts share identical base type (BA9S), voltage rating (12V AC/DC), form factor (T - 3 1/4), color (red), and configuration (single). Direct mechanical and electrical substitution is supported.

Q: What is the primary reason to transition from 1815L-R-CR to 1815LS-R-CR?

A: The 1815L-R-CR is classified as obsolete. The 1815LS-R-CR provides equivalent functionality with active product status, ensuring long-term availability and supply continuity.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What packaging options are available?

A: The 1815L-R-CR packaging specification is not defined. The 1815LS-R-CR is supplied in bulk packaging.

Q: Are these parts suitable for AC and DC applications?

A: Yes. Both parts are rated for 12V AC/DC operation, supporting both alternating and direct current applications.
