Key Parameters

Substitute Part Grouping Explanation

Substitution for the R-B15L1 is determined by strict adherence to the following critical parameters:

• Base Type: E26 medium or standard base is mandatory for mechanical compatibility with existing fixtures
• Voltage Rating: 100VAC operation is required for direct electrical compatibility
• Color Temperature: White or warm color output maintains functional equivalence
• Physical Dimensions: 2.165" diameter x 4.252" height ensures fit within fixture envelopes
• Configuration: Standard light bulb form factor is required
• Applications: Retrofit lighting capability confirms intended use case compatibility

Substitute parts must match all parameters listed above. No deviations from these specifications are permitted for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The R-B15L1 is classified as obsolete. When sourcing this component, the parametric equivalent R-B15L1 maintains full compliance with REACH regulations and EAR99 export classification. Both the main part and its parametric equivalent share identical electrical, mechanical, and regulatory characteristics, ensuring direct substitution capability.

Selection of equivalent parts must prioritize matching the E26 base type, 100VAC voltage rating, and physical dimensions to ensure compatibility with existing retrofit lighting installations. Compliance certifications remain consistent across equivalent alternatives.

Frequently Asked Questions (FAQ)

Q: What makes a part equivalent to the R-B15L1? A: A part is equivalent when it maintains identical base type (E26), voltage rating (100VAC), color output (white or warm), physical dimensions (2.165" Dia x 4.252" H), and standard light bulb configuration for retrofit lighting applications.

Q: Can the R-B15L1 be used in any E26 socket? A: The R-B15L1 is designed for E26 medium or standard base fixtures. Mechanical fit is guaranteed only with E26-compatible sockets. Physical dimensions of 2.165" diameter x 4.252" height must be verified against fixture envelope specifications.

Q: What is the significance of the 100VAC voltage rating? A: The 100VAC rating specifies the operating voltage for this LED light bulb. Direct substitution requires matching this voltage specification to ensure proper electrical operation and safety in retrofit lighting applications.

Q: Why is the R-B15L1 listed as obsolete? A: Obsolete status indicates this product is no longer manufactured by ROHM Semiconductor. Equivalent alternatives with identical specifications remain available for retrofit lighting applications requiring this specific form factor and electrical characteristics.

Q: Are there regulatory considerations for substitution? A: Both the main part and its equivalent maintain REACH Unaffected status and EAR99 export classification, ensuring consistent regulatory compliance across substitution scenarios.
