MRS93-16BB Equivalent & Substitute Parts

Part Overview

The MRS93-16BB is a rocker switch manufactured by Honeywell Sensing and Productivity Solutions, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a current rating of 12A at 125V AC. This panel-mount, snap-in switch features a concave black actuator and quick-connect 0.187" termination. The product is currently obsolete, necessitating identification of equivalent substitute components that maintain functional compatibility for existing applications and new designs requiring replacement inventory.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MRS93-16BB is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPST-NO)
• Switch function (Off-Momentary)
• Mounting type (Panel Mount, Snap-In)
• Termination style (Quick Connect - 0.187")
• Panel cutout dimensions (Rectangular - 19.20mm x 12.90mm)
• Actuator type (Concave)

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 12A
• Voltage rating: Substitute must equal or exceed 125V AC
• Operating temperature range: May differ if application requirements permit
• Mechanical/electrical life cycles: May differ based on application duty cycle
• Product status: Active status preferred for long-term availability

The GRS-4011B-1300 qualifies as a direct substitute based on matching all mandatory parameters while exceeding current rating (13A vs. 12A) and maintaining equivalent voltage specification (125V AC).

Engineering Selection Recommendations

GRS-4011B-1300 Substitution Basis:

The GRS-4011B-1300 is a qualified substitute for the MRS93-16BB based on the following engineering criteria:

1. Functional Equivalence: Both components provide identical SPST-NO switching topology with Off-Momentary operation, ensuring drop-in replacement capability in existing circuit designs.

2. Electrical Compatibility: The substitute's 13A current rating exceeds the original 12A specification, providing margin for load variations. Both operate at 125V AC, maintaining voltage compatibility with existing power distribution systems.

3. Mechanical Compatibility: Identical panel mount snap-in configuration, quick-connect 0.187" termination, and rectangular 19.20mm x 12.90mm cutout dimensions ensure physical interchangeability without panel modification.

4. Regulatory Compliance: Both components maintain RoHS and REACH compliance status, satisfying environmental and hazardous substance restrictions applicable to electronic equipment manufacturing and distribution.

5. Product Availability: The GRS-4011B-1300 holds active product status with 2,844 units in stock, contrasting with the obsolete MRS93-16BB status. This ensures long-term supply chain continuity for new production and field replacement applications.

Application Considerations:

The substitute exhibits a wider operating temperature range (-20°C to 105°C versus 0°C to 85°C), suitable for applications requiring extended thermal performance. However, the electrical life specification of the substitute (25,000 cycles) is lower than the original (50,000 cycles). Applications with high-frequency switching duty cycles should evaluate this parameter against actual operational requirements.

Frequently Asked Questions (FAQ)

Q: Can the GRS-4011B-1300 be directly installed in place of the MRS93-16BB without modifications?

A: Yes. Both components share identical mounting type (panel mount, snap-in), termination style (quick connect 0.187"), and panel cutout dimensions (19.20mm x 12.90mm). No panel modifications or wiring changes are required for mechanical and electrical installation.

Q: What is the significance of the 13A versus 12A current rating difference?

A: The substitute's 13A rating exceeds the original 12A specification, providing 8% additional current capacity. This margin accommodates load variations and inrush current transients without exceeding component limits. The substitute remains suitable for all applications designed for the original 12A-rated component.

Q: Are there compliance differences between the two components?

A: Both components maintain RoHS and REACH compliance. The MRS93-16BB carries RoHS Compliant status, while the GRS-4011B-1300 carries ROHS3 Compliant status. ROHS3 represents the current regulatory standard and is fully backward compatible with RoHS requirements. Both components are REACH Unaffected, indicating no restricted substances of concern.

Q: How does the operating temperature range difference affect substitution?

A: The GRS-4011B-1300 operates across -20°C to 105°C, compared to the MRS93-16BB range of 0°C to 85°C. The substitute's extended range accommodates applications in colder environments and higher-temperature enclosures. Applications operating within the original 0°C to 85°C range experience no thermal performance degradation.

Q: What is the impact of the 50,000 versus 25,000 electrical life cycle difference?

A: The original MRS93-16BB specifies 50,000 electrical life cycles, while the GRS-4011B-1300 specifies 25,000 cycles. For applications with continuous or frequent switching operations, the electrical life specification should be evaluated against actual duty cycle requirements. Applications with moderate switching frequency remain unaffected by this parameter difference.

Q: Is the GRS-4011B-1300 suitable for new product designs?

A: Yes. The GRS-4011B-1300 is classified as an active product with current manufacturing status and adequate inventory availability. It is suitable for both replacement applications and new design implementations requiring SPST-NO rocker switches with 12A/125V AC specifications.

Q: What packaging format is available for the GRS-4011B-1300?

A: The GRS-4011B-1300 is supplied in bulk packaging format. Procurement quantities and packaging configurations should be confirmed with the component supplier based on specific project requirements.
