R-B201L1 Equivalent & Substitute Parts Reference

Part Overview

The R-B201L1 is a standard LED lamp replacement manufactured by Rohm Semiconductor, designed for general purpose lighting applications. It features a medium (E26) base type, operates at 120VAC, and produces warm white light output. The product is classified as obsolete, making identification of equivalent alternatives essential for maintenance, repair, and replacement applications where this component is specified in existing designs or inventory systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the R-B201L1 is determined by strict alignment of the following critical parameters:

• Voltage rating: 120VAC operation
• Base type: E26 medium standard base
• Color specification: White, warm tone
• Configuration: Standard light bulb form factor
• Application category: General purpose lighting
• Compliance: REACH unaffected status and EAR99 export classification

Any equivalent or substitute part must match all of these parameters to ensure direct functional and mechanical compatibility without circuit modification or mechanical adaptation.

Parameter Comparison

Engineering Selection Recommendations

The R-B201L1 is classified as obsolete. When sourcing replacements, prioritize components that maintain identical electrical specifications (120VAC operation), mechanical compatibility (E26 base), and color output (warm white). The part's REACH unaffected status and EAR99 export classification should be preserved in any substitute selection to maintain regulatory compliance and supply chain continuity.

Current inventory of 1090 pieces of new original stock is available. For applications requiring this specific component, direct sourcing of remaining inventory is the primary recommendation. For long-term applications, establish qualified substitute parts that meet all specified parameters to ensure supply security beyond current inventory availability.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the R-B201L1?

A: A valid substitute must match all critical parameters: 120VAC voltage rating, E26 base type, warm white color output, standard light bulb configuration, and general purpose lighting application category. Compliance certifications (REACH unaffected, EAR99) must also align.

Q: Can I use a different base type (e.g., E27 or E24) as a substitute?

A: No. The E26 base type is a mechanical and electrical requirement. Different base types will not fit the fixture and are not compatible.

Q: Does the warm white color specification allow for neutral white or cool white alternatives?

A: No. The color specification is warm white. Neutral or cool white variants have different spectral characteristics and are not parametric equivalents.

Q: Is the 120VAC voltage rating flexible for international applications?

A: No. The R-B201L1 is rated for 120VAC operation. Use of this component at different voltages (e.g., 230VAC) will result in failure or safety hazards.

Q: What is the significance of the obsolete product status?

A: Obsolete status indicates the manufacturer no longer produces this part. Existing inventory (1090 pieces) represents the available supply. For future applications, qualified substitute parts meeting identical parameters should be identified and qualified.

Q: Are there any mechanical dimension or wavelength specifications that affect substitution?

A: The provided specifications do not include detailed dimension or wavelength data. Substitution is based on the parameters provided: voltage, base type, color, configuration, and application category.
