Equivalent & Substitute Parts for JKL Components Corp. 1813

Part Overview

The JKL Components Corp. 1813 is an incandescent lamp with a 14.4V rating, featuring a round domed top lens in RT-3 1/4 size with miniature bayonet base. This component is classified as obsolete, reflecting the industry-wide transition from incandescent to LED lighting technology. Finding equivalent substitute parts is necessary due to discontinued manufacturing and the availability of modern LED alternatives that provide improved reliability, energy efficiency, and extended operational life while maintaining mechanical and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1813 incandescent lamp is determined by the following critical parameters:

• Base Type: Miniature Bayonet connection ensures mechanical compatibility with existing sockets
• Lens Size: RT-3 1/4 (T-3 1/4) maintains physical form factor and optical envelope
• Voltage Rating: Operating voltage must be compatible with the 14.4V supply circuit
• Light Output Characteristics: Luminous intensity and color temperature must be suitable for the intended application

The substitute part LE-BA9S-12W is an LED lamp replacement that maintains the same miniature bayonet base and T-3 1/4 form factor. While the LE-BA9S-12W operates at 12V nominal forward voltage, it is electrically compatible with 14.4V circuits due to the voltage tolerance inherent in LED lamp designs with integrated current-limiting circuitry. The LED technology provides equivalent or superior light output while eliminating the obsolescence risk associated with incandescent technology.

Engineering Selection Recommendations

The LE-BA9S-12W LED lamp is the designated substitute for the obsolete 1813 incandescent lamp. Selection is based on the following factors:

• Product Status: The 1813 is obsolete with no continued manufacturing. The LE-BA9S-12W is active and maintains ongoing production and availability.
• Regulatory Compliance: The LE-BA9S-12W achieves ROHS3 compliance, whereas the 1813 is RoHS non-compliant. This compliance status is critical for applications subject to environmental regulations.
• Mechanical Compatibility: Both components share identical base type (miniature bayonet) and equivalent lens size (RT-3 1/4 / T-3 1/4), ensuring direct socket compatibility without mechanical modification.
• Electrical Compatibility: The LE-BA9S-12W operates at 12V nominal forward voltage and is suitable for 14.4V circuits through integrated voltage regulation within the LED lamp assembly.
• Certifications: Both components maintain REACH Unaffected and EAR99 ECCN classifications, with identical Moisture Sensitivity Level ratings.

Frequently Asked Questions (FAQ)

Q: Can the LE-BA9S-12W directly replace the 1813 in a 14.4V circuit?

A: Yes. The LE-BA9S-12W is designed as a direct replacement for miniature bayonet incandescent lamps in 12V to 14.4V applications. The integrated LED driver circuitry accommodates the voltage differential.

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

A: RT-3 1/4 and T-3 1/4 refer to the same physical lens size (3 1/4 inches in diameter). The "R" prefix on the incandescent designation indicates a round domed top, while the LED designation uses the standard T-series nomenclature. Both fit identical socket envelopes.

Q: Does the color difference between Clear (1813) and White, Cool 6000K (LE-BA9S-12W) affect compatibility?

A: Color is an optical characteristic that does not affect electrical or mechanical compatibility. The choice between clear and white depends on the intended application and desired light output appearance. The LE-BA9S-12W provides higher luminous intensity (7000mcd versus 0.86 MSCP).

Q: Are there any packaging differences between these components?

A: The 1813 is supplied in standard packaging, while the LE-BA9S-12W is supplied in bulk packaging. Both maintain identical Moisture Sensitivity Level (MSL 1) ratings and are suitable for the same storage and handling conditions.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance restricts hazardous substances in electrical equipment. The LE-BA9S-12W's ROHS3 compliance ensures the component meets current environmental and regulatory standards, whereas the obsolete 1813 does not. This is critical for applications in regulated industries or regions with mandatory RoHS requirements.
