FWG203 Equivalent & Substitute Parts

Part Overview

The FWG203 is an incandescent lamp manufactured by JKL Components Corporation, rated at 14V with a clear lens, round domed top design, and RT-1 3/4 wedge configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component sourcing. The RT-1 3/4 wedge lamp category serves applications requiring low-voltage incandescent illumination with standardized mechanical and electrical interfaces.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FWG203 is determined by the following critical parameters:

• Voltage Rating: Must be 14V to ensure direct electrical compatibility
• Lead Style: Must be Wedge to maintain mechanical socket compatibility
• Lens Size: Must be T-1.75 or RT-1 3/4 equivalent to fit standard lamp holders
• Type: Incandescent technology maintains functional equivalence
• MSCP Output: Acceptable range is 0.7 to 0.9 MSCP for equivalent illumination performance

The substitute part CEC Industries 74 meets these criteria with matching voltage, wedge lead configuration, and compatible lens dimensions. The MSCP value of 0.7 falls within the acceptable operational range for this lamp category.

Parameter Comparison

Engineering Selection Recommendations

The CEC Industries 74 lamp is the qualified substitute for the obsolete FWG203. Selection is based on:

• Identical 14V voltage rating ensures direct electrical substitution without circuit modification
• Matching wedge lead style guarantees mechanical compatibility with existing lamp sockets
• Equivalent T-1.75 lens dimensions maintain form factor compatibility
• Active product status ensures ongoing availability and supply chain reliability
• RoHS Compliant certification of the substitute part meets modern regulatory requirements
• MSCP output of 0.7 provides acceptable illumination within the operational envelope for this lamp category

Frequently Asked Questions (FAQ)

Q: Can the CEC Industries 74 be used as a direct replacement for the FWG203?

A: Yes. Both lamps share identical 14V voltage ratings, wedge lead configurations, and equivalent T-1.75 lens dimensions. The substitute is electrically and mechanically compatible for direct socket installation.

Q: What is the significance of the MSCP difference between the two lamps?

A: The FWG203 produces 0.9 MSCP while the CEC Industries 74 produces 0.7 MSCP. This 0.2 MSCP reduction represents a minor decrease in luminous intensity. For applications where precise light output is critical, this difference must be evaluated against system requirements.

Q: Why is the FWG203 listed as obsolete?

A: Obsolete status indicates the FWG203 is no longer in active production by JKL Components Corporation. The CEC Industries 74 remains in active production, providing a current-generation alternative for ongoing component sourcing.

Q: Are there packaging considerations when substituting these lamps?

A: The FWG203 is supplied individually, while the CEC Industries 74 is packaged in boxes of 10 units. Procurement quantities must account for this packaging difference.

Q: Does the substitute meet current compliance standards?

A: Yes. The CEC Industries 74 is RoHS Compliant, meeting current regulatory requirements for electronic component manufacturing and distribution.
