Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4TL150-3D is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (4PDT), current rating (15A AC), and voltage rating (125V AC) must be identical. These parameters define the switch's load-carrying capacity and electrical safety margins.

Mechanical Parameters: Mounting type (Panel Mount), actuator type (Locking Lever), termination style (Screw Terminal), panel cutout dimensions (Circular - 12.40mm Diameter), and bushing thread (15/32-32) must match to ensure physical compatibility with existing panel installations and wiring harnesses.

Environmental Parameters: Ingress protection rating (Environment Sealed) and operating temperature range (-65°C to 71°C) must be maintained to preserve system reliability in the intended application environment.

Compliance Parameters: RoHS compliance status and Moisture Sensitivity Level (MSL 1) must be equivalent or superior to ensure regulatory conformance and handling compatibility.

The 4TL1-3D meets all substitution criteria for the 4TL150-3D based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The 4TL1-3D is the direct substitute for the obsolete 4TL150-3D. Both components are manufactured by Honeywell Sensing and Productivity Solutions and belong to the TL series toggle switch family.

Product Status Consideration: The 4TL150-3D is classified as Obsolete, while the 4TL1-3D maintains Active product status. This status difference indicates that the 4TL1-3D represents the current production equivalent and is the appropriate selection for new designs or component replacement in existing systems.

Compliance and Certification: Both parts maintain RoHS Compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent regulatory conformance and handling requirements. The 4TL1-3D includes REACH Affected status documentation, providing additional environmental compliance transparency.

Electrical and Mechanical Equivalence: All critical electrical parameters (4PDT circuit, 15A AC, 125V AC) and mechanical parameters (panel mount, locking lever, screw terminal, 12.40mm circular cutout, 15/32-32 bushing thread) are identical between the two parts. The 4TL1-3D specifies an actuator length of 26.67mm, which was not documented for the 4TL150-3D but represents the standard specification for this switch family.

Inventory and Availability: The 4TL1-3D is available in higher inventory quantities (1320 pieces) compared to the 4TL150-3D (678 pieces), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 4TL1-3D directly replace the 4TL150-3D in existing panel installations?

A: Yes. The 4TL1-3D maintains identical panel cutout dimensions (12.40mm circular), bushing thread (15/32-32), and all electrical specifications (4PDT, 15A AC, 125V AC). Physical and electrical compatibility is confirmed.

Q: What is the difference between the 4TL150-3D and 4TL1-3D?

A: The primary difference is product status. The 4TL150-3D is Obsolete, while the 4TL1-3D is Active production. The 4TL1-3D explicitly specifies an actuator length of 26.67mm and includes REACH Affected status documentation. All electrical and mechanical parameters are equivalent.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS Compliant with MSL 1 (Unlimited) ratings. The 4TL1-3D provides additional REACH Affected status information. No compliance barriers exist for substitution.

Q: What packaging options are available?

A: The 4TL150-3D packaging is not specified in available documentation. The 4TL1-3D is supplied in Bulk packaging. Confirm packaging requirements with procurement specifications.

Q: Is the 4TL1-3D suitable for the same operating temperature range?

A: Yes. Both parts operate across -65°C to 71°C, maintaining identical thermal performance specifications.

Q: Can I use the 4TL1-3D in applications currently using the 4TL150-3D?

A: Yes. Electrical load capacity (15A AC at 125V), circuit configuration (4PDT On-On), environmental sealing, and mechanical mounting are identical. Direct substitution is supported.
