Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2191QL1-12V is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Voltage Rating: 12V DC operation
• Lamp Color: Red
• Termination Style: Quick Connect - 0.187" (4.7mm)
• Lens Style: Round with Flat Top
• Panel Cutout Shape: Round
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected

Allowable Variations:

• Panel Cutout Dimensions: The substitute part may have a larger panel cutout diameter provided the mechanical mounting interface accommodates the difference
• Current Rating: Substitute parts may have specified current ratings where the original part does not
• Lens Transparency: Diffused lens options are acceptable for red indicator applications
• Lens Color: Red lens color is compatible with red lamp color

The 1092QC1-12V meets all mandatory matching parameters and is classified as an active product with current manufacturing support, making it a direct functional equivalent for the obsolete 2191QL1-12V.

Parameter Comparison

Engineering Selection Recommendations

The 1092QC1-12V is the designated substitute for the obsolete 2191QL1-12V based on the following engineering criteria:

Product Status Alignment: The 1092QC1-12V is an active product with current manufacturing support from VCC, ensuring long-term availability and supply chain continuity compared to the obsolete 2191QL1-12V.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent component substitution.

Electrical Compatibility: Both parts operate at 12V DC with identical quick connect termination (0.187" / 4.7mm), ensuring direct electrical interface compatibility with existing wiring harnesses and connector systems.

Mechanical Considerations: The substitute part features a larger panel cutout diameter (0.50" vs 0.31"), which requires verification that the mounting panel accommodates the increased cutout size. The round lens style with flat top remains consistent between both parts.

Optical Performance: The 1092QC1-12V provides specified optical output (13000mcd) with diffused lens transparency, delivering enhanced visibility compared to the unspecified original part while maintaining red lamp color for consistent visual indication.

Frequently Asked Questions (FAQ)

Q: Can the 1092QC1-12V directly replace the 2191QL1-12V without panel modification?

A: Direct replacement requires verification that the mounting panel accommodates the larger panel cutout diameter of the 1092QC1-12V (0.50" vs 0.31"). If the original panel cutout is 0.31", panel drilling or modification may be necessary.

Q: Are the quick connect terminals identical between both parts?

A: Yes. Both the 2191QL1-12V and 1092QC1-12V use 0.187" (4.7mm) quick connect termination, providing direct electrical interface compatibility without connector modification.

Q: What is the significance of the diffused lens on the substitute part?

A: The diffused lens on the 1092QC1-12V provides wider light distribution compared to a clear lens, improving visibility from multiple viewing angles. This is a functional enhancement for red indicator applications.

Q: Does the 25mA current rating of the 1092QC1-12V affect compatibility?

A: The specified 25mA rating on the substitute part indicates the designed operating current. The original part's unspecified current rating does not preclude substitution, provided the circuit design accommodates the 25mA specification.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 2191QL1-12V and 1092QC1-12V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.

Q: What is the primary reason for substitution?

A: The 2191QL1-12V is classified as obsolete, meaning it is no longer manufactured. The 1092QC1-12V is an active product with current manufacturing support, ensuring availability for replacement and new applications.
