LED Panel Indicator 2191UX1-12V Equivalent & Substitute Parts

Part Overview

The 2191UX1-12V is a red LED panel indicator light manufactured by Visual Communications Company (VCC), designed for 12V applications with wire lead termination. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance requirements. The 2191UX1-12V features a round domed lens with 0.31" (7.87mm) panel cutout dimensions and 4.6" (116.84mm) wire leads. Due to its obsolete status, sourcing active alternatives from the same product series ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2191UX1-12V is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Voltage rating: 12V (exact match required)
• Lamp color: Red (exact match required)

Mechanical Parameters:

• Panel cutout shape: Round (exact match required)
• Panel cutout dimensions: 0.31" (7.87mm) (exact match required)
• Lens style: Round with Domed Top (exact match required)
• Termination style: Wire Leads - 4.6" (116.84mm) (exact match required)

Compliance Parameters:

• RoHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level 1 (Unlimited)

The substitute part 2191U1-12V meets all specified parameters and belongs to the same 2191U series, confirming functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 2191U1-12V is the direct equivalent for the obsolete 2191UX1-12V. Selection of the 2191U1-12V is based on the following engineering criteria:

Product Status: The 2191U1-12V maintains active product status with VCC, ensuring continued availability and supply chain support. The original 2191UX1-12V is classified as obsolete, making the active 2191U1-12V the appropriate selection for new designs and ongoing production.

Compliance Certification: Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level 1 (Unlimited) ratings, confirming equivalent environmental and regulatory standing.

Electrical and Mechanical Equivalence: All specified electrical parameters (12V, red lamp color) and mechanical parameters (round 0.31" panel cutout, round domed lens, 4.6" wire leads) are identical between the main part and substitute, confirming direct functional interchangeability.

Inventory Availability: The 2191U1-12V is available in higher inventory quantity (1287 Pcs) compared to the obsolete 2191UX1-12V (907 Pcs), supporting production continuity.

Frequently Asked Questions (FAQ)

Q: Can the 2191U1-12V directly replace the 2191UX1-12V in existing designs?

A: Yes. The 2191U1-12V is a direct equivalent. All electrical parameters (12V operation, red lamp color), mechanical parameters (0.31" round panel cutout, round domed lens, 4.6" wire leads), and compliance certifications (ROHS3, MSL 1) are identical.

Q: What is the difference between the 2191UX1-12V and 2191U1-12V?

A: The primary difference is product status. The 2191UX1-12V is obsolete, while the 2191U1-12V is active. The packaging differs (2191UX1-12V uses standard packaging; 2191U1-12V uses bulk packaging), but all functional and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the 2191U1-12V for the 2191UX1-12V?

A: No compatibility concerns exist. Both parts are from the same 2191U series, share identical panel cutout dimensions, lens style, voltage rating, and termination configuration. Direct substitution is supported.

Q: Does the 2191U1-12V meet the same regulatory requirements as the 2191UX1-12V?

A: Yes. Both parts are ROHS3 compliant and carry identical Moisture Sensitivity Level 1 (Unlimited) ratings, confirming equivalent regulatory and environmental compliance.

Q: What packaging format is the 2191U1-12V supplied in?

A: The 2191U1-12V is supplied in bulk packaging, compared to standard packaging for the 2191UX1-12V. Bulk packaging does not affect component functionality or performance.
