Bulgin LH1048S LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The Bulgin LH1048S is an LED panel indicator holder designed for T1 3/4 form factor lamps with a 0.315" (8.00mm) round panel cutout. This chrome-finished component is classified as an active product and serves as a mechanical mounting and retention solution for LED indicator assemblies in panel-mount applications. Substitute parts are identified based on matching mechanical specifications, electrical compatibility parameters, and regulatory compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LH1048S is determined by the following criteria:

Primary Matching Parameters:

• Panel cutout shape: Round
• Panel cutout dimensions: 0.315" (8.00mm)
• Lamp form factor: T1 3/4
• Product status: Active
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts match these core mechanical and regulatory parameters. Variations exist in finish color (chrome versus black) and packaging designation (standard versus specialty), but these do not affect functional interchangeability for the specified panel cutout and lamp form factor.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products manufactured by Bulgin with ROHS3 compliance and MSL rating of 1 (Unlimited). Selection among equivalent parts should be based on:

1. Availability: Inventory levels vary across part numbers. LH1048 offers the highest stock position at 4754 units.

2. Finish Specification: Chrome finish variants (LH1048S, LH1050S) differ from black finish variants (LH1048B, LH1048BS, LH1050B). Finish selection is determined by application aesthetic and environmental requirements.

3. Series Designation: LH1048 series and LH1050 series are both qualified substitutes. Series selection does not affect mechanical compatibility for the specified panel cutout dimensions.

4. Regulatory Compliance: All parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence across substitution options.

Frequently Asked Questions (FAQ)

Q: Can LH1048B be used as a direct replacement for LH1048S?

A: Yes. Both parts share identical panel cutout dimensions (0.315" / 8.00mm), round shape, T1 3/4 lamp form factor, and regulatory compliance. The difference is finish color: LH1048S is chrome, LH1048B is black. Selection depends on application requirements.

Q: What is the difference between LH1048 and LH1050 series parts?

A: Both series accommodate the same panel cutout dimensions and lamp form factor. Series designation reflects internal design variations that do not affect mechanical interchangeability for the specified 0.315" (8.00mm) round cutout.

Q: Is A104800AAC compatible with LH1048S applications?

A: Yes. A104800AAC meets all mechanical and regulatory parameters: 0.315" (8.00mm) round panel cutout, T1 3/4 form factor, ROHS3 compliance, and MSL 1 rating. It is functionally equivalent for panel-mount LED indicator applications.

Q: Are there electrical parameter differences between substitute parts?

A: No electrical parameters are specified for any part in this product family. These are mechanical holders designed to accommodate LED lamps; electrical characteristics are determined by the lamp assembly, not the holder.

Q: What does MSL 1 (Unlimited) mean for these parts?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these components have unlimited shelf life under standard storage conditions and require no special moisture control during handling or storage.

Q: Can I mix chrome and black finish parts in the same assembly?

A: Mechanical compatibility is identical across all finish variants. Mixing finishes is permissible from an engineering standpoint; aesthetic consistency is determined by application design requirements.
