LED Panel Indicator 2191U5-6V Equivalent & Substitute Parts

Part Overview

The 2191U5-6V is an active green LED panel indicator manufactured by Visual Communications Company (VCC), designed for 6V applications with wire lead termination. This component is a panel-mount indicator featuring a round domed lens and 0.31" (7.87mm) panel cutout. The part is ROHS3 compliant and maintains MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions.

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable, while maintaining electrical and mechanical compatibility within the specified parameter constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2191U5-6V is determined by strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Voltage Rating: 6V (exact match required)
• Lamp Color: Green (fixed optical requirement)
• Type: LED Panel Indicator (functional category)

Mechanical Compatibility Parameters:

• Panel Cutout Shape: Round (mounting interface)
• Panel Cutout Dimensions: 0.31" (7.87mm) (panel fit requirement)
• Termination Style: Wire Leads - 4.6" (116.84mm) (connection method and lead length)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (storage classification)

The 2191L5-6V qualifies as a substitute part because it matches all critical electrical, mechanical, and compliance parameters. The only difference is the lens style (flat top versus domed top), which does not affect electrical function or mechanical panel mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 2191U5-6V and 2191L5-6V are active products manufactured by VCC with identical ROHS3 compliance and MSL Level 1 ratings. Selection between these parts should be based on the following engineering considerations:

Primary Selection Criteria:

• Panel aesthetic requirements: The 2191U5-6V features a domed lens top, while the 2191L5-6V features a flat lens top. Choose based on visual design specifications for the end application.
• Inventory availability: The 2191L5-6V currently maintains higher inventory levels (5640 Pcs) compared to the 2191U5-6V (896 Pcs), which may influence lead time considerations.

Compliance Assurance: Both parts maintain identical regulatory compliance status (ROHS3 Compliant, REACH Unaffected, ECCN EAR99, HTSUS 8541.41.0000), ensuring no compliance risk in substitution.

Electrical and Mechanical Assurance: Voltage rating, panel cutout dimensions, wire lead length, and termination style are identical across both parts, confirming direct functional interchangeability in 6V panel-mount applications.

Frequently Asked Questions (FAQ)

Q: Can the 2191L5-6V directly replace the 2191U5-6V in my application?

A: Yes, the 2191L5-6V is electrically and mechanically compatible with the 2191U5-6V. Both parts operate at 6V, feature identical 0.31" (7.87mm) round panel cutouts, and use 4.6" wire leads. The only difference is the lens style (flat top versus domed top), which affects visual appearance but not electrical function or mechanical fit.

Q: What is the difference between the domed lens (2191U5-6V) and flat lens (2191L5-6V)?

A: The lens style difference is purely optical and aesthetic. The 2191U5-6V has a round domed top, while the 2191L5-6V has a round flat top. Both provide the same light emission from a green LED at 6V. Selection depends on the visual design requirements of your panel or enclosure.

Q: Are both parts RoHS compliant?

A: Yes, both the 2191U5-6V and 2191L5-6V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the panel cutout requirement for these parts?

A: Both parts require a round panel cutout of 0.31" (7.87mm) diameter. This dimension is identical for both the main part and substitute, ensuring mechanical interchangeability in existing panel designs.

Q: Do these parts have any moisture sensitivity concerns?

A: No. Both parts carry an MSL Level 1 rating, which indicates unlimited shelf life under standard storage conditions. No special moisture control measures are required during storage or handling.

Q: What is the wire lead length for these indicators?

A: Both the 2191U5-6V and 2191L5-6V feature wire leads of 4.6" (116.84mm) length, providing identical electrical connection routing options in circuit design.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your application design does not have specific aesthetic requirements for lens shape. From an electrical and mechanical standpoint, both parts are fully interchangeable in 6V panel-mount indicator applications.
