Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for incandescent lamps is determined by matching the following critical parameters:

• Voltage Rating: 14.4V (exact match required)
• MSCP Output: 0.75 (exact match required)
• Lens Size: RT-3 1/4 or equivalent T-3.25 designation
• Base Type: Miniature Bayonet or BA9S single-contact bayonet (functionally equivalent)
• Color: Clear (optical characteristic match)

The CEC Industries part number 1892 meets all substitution criteria through equivalent electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CEC Industries part number 1892 is the qualified substitute for the obsolete JKL Components 1892. Selection is based on:

• Identical voltage rating and light output (MSCP 0.75)
• Equivalent lens geometry (RT-3 1/4 and T-3.25 are interchangeable designations)
• Compatible bayonet base configuration (BA9S single-contact bayonet)
• Active product status ensuring ongoing availability
• Matching export classification (EAR99)
• Current inventory availability (803 units in stock)

Frequently Asked Questions (FAQ)

Q: Are RT-3 1/4 and T-3.25 lens sizes interchangeable? A: Yes. RT-3 1/4 and T-3.25 are equivalent designations for the same physical lens diameter and domed-top geometry used in miniature incandescent lamps.

Q: Does the BA9S bayonet base match the miniature bayonet specification? A: Yes. BA9S is the standard single-contact bayonet base for miniature incandescent lamps and is mechanically and electrically compatible with miniature bayonet applications.

Q: Why is the original JKL Components part obsolete? A: The product status reflects manufacturer discontinuation. The CEC Industries equivalent remains in active production and is the recommended procurement source.

Q: Are there packaging differences between the two parts? A: The CEC Industries part is supplied in boxes of 10 units. Verify packaging requirements for your application before procurement.

Q: Can this lamp be used in RoHS-compliant applications? A: No. Both the original and substitute parts are RoHS non-compliant. Applications requiring RoHS compliance require alternative lamp technologies.
