PL-19-RC000 Equivalent & Substitute Parts

Part Overview

The PL-19-RC000 is an incandescent panel indicator manufactured by Littelfuse Inc., featuring a red lens with wire leads measuring 8" (203.20mm). This component is classified as obsolete, making identification of suitable alternatives essential for ongoing system maintenance and new design implementations. The transition from incandescent to LED technology provides modern substitutes that maintain functional compatibility while offering improved reliability and operational characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PL-19-RC000 is determined by the following critical parameters:

• Panel Cutout Shape & Dimensions: Round configuration required for mechanical fit
• Lens Color & Style: Red lens with round domed top for visual consistency
• Termination Style: Wire leads for direct integration into existing harnesses
• Ratings: DC operation for compatibility with system voltage supplies
• RoHS Compliance: ROHS3 compliance maintained across substitutes

The 1092D1-12V qualifies as a manufacturer-recommended substitute despite the transition from incandescent to LED technology. This substitution is valid because the mechanical interface (round panel cutout, domed lens style, wire lead termination) and electrical ratings (DC operation, RoHS3 compliance) align with the original component's functional requirements.

Parameter Comparison

Engineering Selection Recommendations

The 1092D1-12V is the manufacturer-recommended substitute for the obsolete PL-19-RC000. Selection of this alternative is supported by:

• Active Product Status: The 1092D1-12V maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both components maintain ROHS3 compliance, satisfying environmental and regulatory requirements
• Mechanical Compatibility: Round domed lens style and wire lead termination provide direct functional replacement in panel-mounted applications
• Electrical Ratings: DC operation at 12V with 25mA current specification aligns with typical panel indicator circuit requirements

Panel cutout dimension differences (0.75" vs. 0.50") and wire lead length variations (8" vs. 4.6") require mechanical verification during integration to confirm fit within existing panel assemblies and harness routing constraints.

Frequently Asked Questions (FAQ)

Q: Why is the PL-19-RC000 being replaced? A: The PL-19-RC000 is classified as obsolete and no longer manufactured by Littelfuse Inc. The 1092D1-12V provides functional equivalence while maintaining active production status.

Q: What are the key compatibility factors for substitution? A: Mechanical fit (round panel cutout, domed lens style, wire lead termination) and electrical operation (DC ratings, RoHS3 compliance) determine substitution validity. Panel cutout dimensions and wire lead lengths must be verified for specific applications.

Q: Does the panel cutout dimension difference affect installation? A: The substitute part features a smaller panel cutout dimension (0.50" vs. 0.75"). Mechanical verification is required to confirm compatibility with existing panel assemblies. Adapter rings or panel modifications may be necessary.

Q: Are the wire lead lengths interchangeable? A: The substitute provides shorter wire leads (4.6" vs. 8"). Harness routing and connection point distances must be evaluated to confirm adequate lead length for system integration.

Q: What voltage and current specifications apply to the substitute? A: The 1092D1-12V operates at 12V DC with a current draw of 25mA. System voltage supply and circuit current capacity must be verified for compatibility.

Q: Are both components RoHS compliant? A: Yes, both the PL-19-RC000 and 1092D1-12V maintain ROHS3 compliance, satisfying environmental and regulatory requirements for electronic component manufacturing and use.
