Substitute Part Grouping Explanation
Substitution eligibility for the 2191U7-24V is determined by the following critical parameters:
Mandatory Matching Parameters:
- Operating voltage: 24V
- Lamp color: Yellow
- Lens style: Round with domed top
- Termination style: Wire leads with 4.6" length
- Panel cutout shape: Round
Allowable Variation Parameters:
- Panel cutout dimensions: Substitutes may have different cutout diameters provided the mechanical mounting interface accommodates the variation
- Product status: Active status substitutes are acceptable for obsolete parts
- Series designation: Different series numbers are acceptable if all electrical and mechanical parameters align
The 1091M7-24V qualifies as a substitute based on matching voltage, lamp color, lens style, wire lead termination, and round panel cutout configuration. The panel cutout dimension difference (0.50" versus 0.31") represents the primary mechanical consideration for integration assessment.
Parameter Comparison
| Parameter | 2191U7-24V (Main Part) | 1091M7-24V (Substitute) | Match Status |

| Lamp Color | Yellow | Yellow | Identical |
| Operating Voltage | 24V | 24V | Identical |
| Panel Cutout Shape | Round | Round | Identical |
| Panel Cutout Dimensions | 0.31" (7.87mm) | 0.50" (12.70mm) | Different |
| Lens Style | Round with Domed Top | Round with Domed Top | Identical |
| Termination Style | Wire Leads - 4.6" (116.84mm) | Wire Leads - 4.6" (116.84mm) | Identical |
| Product Status | Obsolete | Active | Substitute is Active |
| RoHS Compliance | ROHS3 Compliant | ROHS3 Compliant | Identical |
| MSL Rating | 1 (Unlimited) | 1 (Unlimited) | Identical |
| REACH Status | REACH Unaffected | REACH Unaffected | Identical |
Engineering Selection Recommendations
The 1091M7-24V serves as a functional equivalent for the obsolete 2191U7-24V based on electrical and optical parameter alignment. Both components maintain identical 24V operating voltage, yellow lamp color output, and wire lead termination specifications. Both parts satisfy ROHS3 compliance and REACH regulatory requirements, ensuring compatibility with current environmental standards.
The primary engineering consideration is the panel cutout dimension variance. The 1091M7-24V requires a 0.50-inch (12.70mm) round cutout compared to the 0.31-inch (7.87mm) cutout of the original part. Panel redesign or mechanical adapter solutions may be necessary depending on existing mounting infrastructure. The active product status of the 1091M7-24V provides supply chain continuity and ongoing manufacturer support compared to the obsolete 2191U7-24V.
Frequently Asked Questions (FAQ)
Q: Can the 1091M7-24V directly replace the 2191U7-24V without panel modification?
A: Electrical and optical functionality are compatible. However, the panel cutout dimension difference (0.50" versus 0.31") requires assessment of the existing panel mounting hole. Direct replacement is possible only if the panel cutout can accommodate the larger 0.50-inch diameter, or if mechanical adaptation is implemented.
Q: Are there any voltage or current rating differences between these parts?
A: Both components operate at 24V. Current ratings are not specified in the available technical parameters for either part. Consult detailed datasheets for current consumption specifications if this parameter is critical for circuit design.
Q: What is the significance of the product status difference?
A: The 2191U7-24V is classified as obsolete, indicating discontinued manufacturing and limited availability. The 1091M7-24V maintains active status, ensuring ongoing production, availability, and manufacturer technical support. Active status parts are preferred for new designs and long-term supply chain planning.
Q: Do both parts meet the same regulatory compliance standards?
A: Yes. Both the 2191U7-24V and 1091M7-24V are ROHS3 compliant and REACH unaffected, satisfying current environmental and hazardous substance regulations. Both parts carry MSL rating 1 (unlimited moisture sensitivity level), indicating no special storage or handling requirements.
Q: What packaging options are available?
A: The 2191U7-24V is available in standard packaging with 1031 pieces in current inventory. The 1091M7-24V is supplied in bulk packaging with 1010 pieces in current inventory. Packaging format selection depends on procurement volume and storage requirements.
Q: Are the wire lead lengths identical?
A: Yes. Both components feature 4.6-inch (116.84mm) wire leads, ensuring identical termination length for circuit integration and panel mounting applications.
