Honeywell 1NT1-2F Toggle Switch SPST 15A 125V Equivalent & Substitute Parts

Part Overview

The Honeywell 1NT1-2F is a panel-mount toggle switch with SPST (Single Pole Single Throw) circuit configuration, rated for 15A at 125V AC. This component features a locking lever actuator, sealed construction with IP67/IP68 ingress protection, and screw terminal termination. The 1NT1-2F is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this switch configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1NT1-2F are identified based on strict electrical and mechanical parameter matching within the Honeywell NT series. The substitution logic is based on the following critical parameters that must remain identical:

Electrical Parameters (Non-Negotiable):

• Circuit configuration: SPST
• Current rating: 15A AC
• Voltage rating: 125V AC
• Switch function: On-Off

Mechanical Parameters (Non-Negotiable):

• Mounting type: Panel Mount
• Actuator type: Locking Lever
• Actuator length: 26.67mm
• Termination style: Screw Terminal
• Panel cutout dimensions: Circular - 12.40mm Dia
• Bushing thread: 15/32-32

Environmental Parameters (Non-Negotiable):

• Ingress protection: IP67/IP68
• Operating temperature range: -40°C to 71°C
• Sealed construction

Parts meeting all these criteria are classified as direct substitutes. Variations in product status, packaging format, or compliance certifications do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

The 1NT1-2D is a direct functional equivalent to the 1NT1-2F. All critical electrical, mechanical, and environmental parameters are identical. The primary distinction is product status: the 1NT1-2F is obsolete while the 1NT1-2D maintains active status with current manufacturing support.

Compliance Considerations:

The 1NT1-2F carries RoHS Compliant certification. The 1NT1-2D carries ROHS3 Compliant certification, representing an enhanced compliance level. Both parts meet RoHS requirements and are suitable for applications requiring RoHS-compliant components.

The 1NT1-2D includes REACH Unaffected status, indicating full compliance with REACH regulations.

Packaging Difference:

The 1NT1-2F is supplied in standard packaging format. The 1NT1-2D is supplied in bulk packaging. This difference affects order quantities and logistics but does not impact electrical or mechanical performance.

Inventory and Availability:

Current inventory shows 775 units of 1NT1-2F (obsolete status) and 774 units of 1NT1-2D (active status). For new designs or ongoing production, the 1NT1-2D is the appropriate selection due to active product status and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the 1NT1-2D directly replace the 1NT1-2F in existing applications?

A: Yes. All electrical ratings (15A, 125V AC, SPST), mechanical dimensions (26.67mm actuator, 12.40mm panel cutout, 15/32-32 bushing thread), and environmental specifications (IP67/IP68, -40°C to 71°C) are identical. Direct substitution is functionally equivalent.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with RoHS (Restriction of Hazardous Substances) requirements. ROHS3 represents the current version of the RoHS directive. Both parts meet hazardous substance restrictions and are suitable for regulated applications.

Q: Does the bulk packaging of the 1NT1-2D affect performance compared to the standard packaging of the 1NT1-2F?

A: No. Packaging format does not affect electrical or mechanical performance. Bulk packaging is a logistics and ordering consideration only. Component functionality remains identical.

Q: Why is the 1NT1-2F listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The 1NT1-2D is the active equivalent and is recommended for all new applications and ongoing production requirements.

Q: Are there any electrical parameter differences between these parts?

A: No. Current rating (15A AC), voltage rating (125V AC), circuit configuration (SPST), and switch function (On-Off) are identical across both part numbers.

Q: What does IP67/IP68 ingress protection mean for this switch?

A: IP67/IP68 rating indicates the switch is dust tight and waterproof. This sealed construction is maintained in both the 1NT1-2F and 1NT1-2D.

Q: Can this switch operate across the full temperature range in both specifications?

A: Yes. Both the 1NT1-2F and 1NT1-2D are rated for operation from -40°C to 71°C. Operating temperature capability is identical.
