• Voltage rating: 125V (AC and DC)

Mechanical Equivalence Requirements:

• Actuator type: Push-Pull Plunger
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force: 1814gf
• Operating position: 0.203" (5.2mm)
• Overtravel: 0.125" (3.2mm)

Compliance Requirements:

• RoHS Compliant
• Moisture Sensitivity Level 1

The substitute part 22AC1 meets all specified electrical, mechanical, and compliance parameters, establishing direct functional equivalence with the 2AC19.

Engineering Selection Recommendations

The Honeywell 22AC1 is the direct equivalent substitute for the obsolete 2AC19 snap action switch. Selection is based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical current and voltage ratings (15A AC / 500mA DC at 125V), ensuring direct functional replacement in existing circuits without modification.

Mechanical Compatibility: Identical actuator type, mounting configuration, termination style, operating force, and travel specifications confirm mechanical interchangeability in existing mechanical assemblies and panel layouts.

Compliance Status: Both parts are RoHS Compliant with Moisture Sensitivity Level 1, meeting current regulatory requirements. The 22AC1 additionally carries REACH Affected status, reflecting current compliance documentation.

Product Status Advantage: The 22AC1 is classified as Active, ensuring ongoing availability, technical support, and supply chain continuity. The 2AC19 obsolete status creates supply risk and limits access to manufacturer documentation and support.

Operating Temperature: The 22AC1 provides a specified operating temperature range of -18°C to 82°C, offering defined thermal performance parameters for system design verification.

Frequently Asked Questions (FAQ)

Q: Can the 22AC1 directly replace the 2AC19 without any modifications?

A: Yes. The 22AC1 is electrically and mechanically equivalent to the 2AC19 across all specified parameters. Direct substitution is possible without circuit modifications, mechanical redesign, or panel layout changes.

Q: What is the primary reason for substituting the 2AC19?

A: The 2AC19 is classified as obsolete, creating supply availability risk. The 22AC1 is an active product from the same manufacturer with identical electrical and mechanical specifications, ensuring long-term availability and supply chain continuity.

Q: Are there differences in packaging between the 2AC19 and 22AC1?

A: The 2AC19 is supplied with unspecified packaging, while the 22AC1 is supplied in Bulk packaging. Both parts are identical in form, fit, and function. Packaging differences do not affect component performance or interchangeability.

Q: Does the 22AC1 have better specifications than the 2AC19?

A: The 22AC1 provides an additional specified operating temperature range (-18°C to 82°C) not documented for the 2AC19. All other electrical and mechanical parameters are identical. The temperature specification provides additional design verification data for thermal applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2AC19 and 22AC1 are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited). The 22AC1 additionally carries REACH Affected status, reflecting current regulatory documentation standards.

Q: What is the inventory status for each part?

A: The 2AC19 has 792 pieces in stock (obsolete status). The 22AC1 has 1317 pieces in stock (active status). For new designs and long-term applications, the 22AC1 is recommended due to active product status and higher inventory availability.

Q: Are the screw terminal connections identical between both parts?

A: Yes. Both parts use identical screw terminal termination style, ensuring direct connection compatibility in existing wiring harnesses and terminal blocks without modification.
