Honeywell 1AC1 Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The Honeywell 1AC1 is a snap action switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 15A at 125V AC and 500mA at 125V DC. This component features a push-pull plunger actuator and chassis mount termination with screw terminals. The 1AC1 is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

The primary reason for identifying substitute parts is the obsolete product status of the 1AC1. Active equivalent models ensure continued availability and supply chain reliability for applications requiring this switch configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Honeywell 1AC1 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Circuit type (SPDT), switch function (On-Momentary), current ratings (15A AC / 500mA DC), and voltage ratings (125V AC / 125V DC).

Mechanical Parameters: Actuator type (push-pull plunger), mounting configuration (chassis mount), termination method (screw terminal), operating force (1588gf), operating position (0.250"), and overtravel (0.125").

Environmental & Compliance: Operating temperature range (-55°C to 125°C), RoHS compliance, and MSL rating (1).

Manufacturer Consistency: All substitute parts are sourced from Honeywell Sensing and Productivity Solutions to ensure design continuity and quality assurance.

Parts meeting all these criteria are classified as direct equivalents and may be used interchangeably in applications originally specified for the 1AC1.

Parameter Comparison

Engineering Selection Recommendations

The Honeywell 1AC2 is the direct active equivalent for the obsolete 1AC1. All electrical, mechanical, and environmental specifications are identical. The 1AC2 maintains the same SPDT circuit configuration, 15A AC / 500mA DC current ratings, 125V voltage ratings, push-pull plunger actuator, chassis mount configuration, and screw terminal termination.

Both parts are RoHS compliant and carry MSL 1 rating, indicating no moisture sensitivity restrictions. Both are classified under ECCN EAR99 and HTSUS code 8536.50.9040, confirming regulatory and trade classification equivalence.

The transition from 1AC1 to 1AC2 is supported by active product status for the 1AC2, ensuring long-term availability and supply chain continuity. No design modifications or application adjustments are required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can the 1AC2 be used as a direct replacement for the 1AC1?

A: Yes. The 1AC2 is a direct equivalent with identical electrical ratings (15A AC, 500mA DC, 125V AC/DC), mechanical configuration (push-pull plunger, chassis mount, screw terminal), and environmental specifications (-55°C to 125°C operating range). No circuit modifications are required.

Q: What is the primary difference between the 1AC1 and 1AC2?

A: The 1AC1 is obsolete, while the 1AC2 is active. All technical specifications are identical. The 1AC2 is the recommended part for new procurement and ongoing applications.

Q: Are there packaging differences between these parts?

A: The 1AC1 is packaged individually, while the 1AC2 is supplied in bulk packaging. Both contain the same component with identical electrical and mechanical properties. Packaging selection depends on procurement volume requirements.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the 1AC1 and 1AC2 are RoHS compliant and carry MSL 1 rating with unlimited moisture sensitivity protection.

Q: Are there any export or trade restrictions for these parts?

A: Both parts are classified under ECCN EAR99 and HTSUS code 8536.50.9040, indicating identical regulatory treatment for export and trade purposes.

Q: What is the operating force specification, and does it differ between parts?

A: Both parts specify an operating force of 1588gf with identical operating position (0.250" / 6.4mm) and overtravel (0.125" / 3.2mm). These mechanical parameters are identical across both models.
