EWG203 Equivalent & Substitute Parts

Part Overview

The EWG203 is an incandescent lamp manufactured by JKL Components Corp., designed as a clear 14V round wedge-base lamp with a domed top in RT-1 1/2 size. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and repair applications. The lamp operates at 14V with a Mean Spherical Candle Power (MSCP) rating of 0.9 and employs a wedge lead style for direct socket compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EWG203 is determined by the following critical parameters:

• Voltage Rating: Must be 14V to ensure safe operation within the host system
• Lead Style: Must be Wedge to maintain mechanical and electrical compatibility with existing sockets
• Lens Size: Must accommodate T-1.5 or RT-1 1/2 form factors for physical fit
• Type: Incandescent lamp technology
• Color: Clear lens specification

The E74 substitute part from CEC Industries meets these core substitution criteria. Both parts operate at 14V with wedge-base leads and clear lens construction, enabling direct functional replacement in applications designed for the EWG203.

Parameter Comparison

Engineering Selection Recommendations

The E74 from CEC Industries is the manufacturer-recommended substitute for the obsolete EWG203. Both components share identical voltage ratings (14V) and wedge-base lead styles, ensuring mechanical and electrical compatibility. The E74 is currently in active production status, providing reliable supply availability for replacement applications.

The MSCP difference (0.9 versus 0.7) reflects a variance in luminous intensity output. This parameter variance should be evaluated against specific application requirements to determine acceptability in the target system.

Both parts carry identical ECCN (EAR99) and REACH compliance classifications, confirming regulatory equivalence for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can the E74 be used as a direct replacement for the EWG203?

A: Yes. Both parts operate at 14V with wedge-base leads and clear lens construction. The E74 is the manufacturer-recommended substitute and maintains electrical and mechanical compatibility with systems designed for the EWG203.

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

A: MSCP (Mean Spherical Candle Power) measures luminous intensity. The EWG203 produces 0.9 MSCP while the E74 produces 0.7 MSCP. This represents approximately 22% lower light output. Applications requiring specific brightness levels should verify this variance against system specifications.

Q: Why is the EWG203 obsolete?

A: The EWG203 is no longer manufactured by JKL Components Corp. The E74 substitute is actively produced by CEC Industries, providing continued availability for replacement and maintenance applications.

Q: Are there packaging differences between these parts?

A: The E74 is supplied in boxes of 10 units. Verify packaging requirements for your application, as the EWG203 original packaging specifications are not provided in this reference.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the EWG203 and E74 carry identical ECCN (EAR99) classifications and REACH Unaffected status, confirming regulatory equivalence for compliance purposes.
