FLPR2-UBW Equivalent & Substitute Parts

Part Overview

The FLPR2-UBW is a light pipe LED assembly manufactured by Bivar Inc. This component is classified as obsolete and is no longer in active production. The product remains available in limited inventory (767 pieces) as new original stock. Due to its obsolete status, identification of functionally equivalent substitute components is necessary for ongoing system maintenance, repair, and new design implementations where similar optical coupling functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FLPR2-UBW light pipe assembly is based on the following criteria derived from available component specifications:

Primary Substitution Logic:

The identified substitute part SSF-LXH100USBD-01 represents a functionally related LED indicator component. Substitution eligibility is determined by:

1. Moisture Sensitivity Compatibility – Both components share MSL 1 (Unlimited), indicating equivalent environmental tolerance
2. Mounting Configuration – The substitute provides through-hole mounting with right-angle orientation, suitable for PCB integration
3. Optical Output Characteristics – The substitute delivers defined luminous intensity (40mcd) and viewing angle (60°) for indicator applications
4. Compliance Status – The substitute maintains active product status with current RoHS3 and REACH compliance certifications

Substitution Constraints:

The FLPR2-UBW is a light pipe assembly (optical coupling element), while SSF-LXH100USBD-01 is a complete LED circuit board indicator. Direct mechanical and functional equivalence cannot be confirmed from provided specifications. Component selection must account for specific application requirements regarding optical path, mounting geometry, and electrical interface.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement:

The FLPR2-UBW obsolete status necessitates substitute identification for new production and field service applications. The SSF-LXH100USBD-01 is available as an active product with current manufacturing support and compliance certifications (RoHS3, REACH).

Compliance Considerations:

Both components maintain MSL 1 classification, indicating no moisture-related handling restrictions. The substitute part carries current regulatory compliance (RoHS3 Compliant, REACH Unaffected, EAR99 ECCN), suitable for applications requiring documented compliance documentation.

Inventory Availability:

Current stock of FLPR2-UBW (767 pieces) supports limited-duration applications. The substitute SSF-LXH100USBD-01 maintains active inventory (818 pieces) with ongoing manufacturing availability through Lumex Opto/Components Inc.

Application-Specific Validation:

Component selection between the obsolete FLPR2-UBW and substitute SSF-LXH100USBD-01 requires verification of:

• Mechanical mounting interface compatibility with existing PCB layouts
• Optical coupling requirements and light pipe functionality
• Electrical interface specifications (voltage, current, impedance)
• Physical form factor constraints within system enclosures

Frequently Asked Questions (FAQ)

Q: Why is the FLPR2-UBW classified as obsolete?

A: The FLPR2-UBW is no longer manufactured by Bivar Inc. and has been discontinued from active production. Obsolete classification indicates end-of-life status with no new manufacturing planned.

Q: What is the functional difference between a light pipe and an LED circuit board indicator?

A: A light pipe is an optical coupling element that transmits light from a source to a remote location. An LED circuit board indicator is a complete assembly combining the LED source, optical element, and electrical interface on a single component. The FLPR2-UBW light pipe requires integration with a separate LED source, while the SSF-LXH100USBD-01 is a self-contained indicator.

Q: Are the FLPR2-UBW and SSF-LXH100USBD-01 directly interchangeable?

A: Direct interchangeability cannot be confirmed from available specifications. The components serve related but distinct functions. Substitution requires validation of mechanical mounting, optical performance, and electrical interface compatibility within the specific application.

Q: What does MSL 1 (Unlimited) mean for both components?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Both parts can be stored and handled without special moisture control measures, simplifying inventory management and field service procedures.

Q: Is the SSF-LXH100USBD-01 compliant with current regulatory requirements?

A: Yes. The SSF-LXH100USBD-01 is RoHS3 Compliant and REACH Unaffected, meeting current environmental and hazardous substance regulations applicable to electronic components in most markets.

Q: How long will FLPR2-UBW inventory remain available?

A: Current inventory is 767 pieces. Availability duration depends on consumption rate. Once exhausted, no additional stock will be manufactured. The SSF-LXH100USBD-01 maintains active production status with ongoing availability.

Q: What mounting configuration does the substitute part provide?

A: The SSF-LXH100USBD-01 features through-hole mounting with right-angle orientation, designed for direct PCB insertion and soldering. Verify compatibility with existing PCB footprints and mounting hole patterns.
