Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 17AC34-T is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit type (SPDT), current rating (5A AC/DC), voltage ratings (250V AC / 30V DC), and switch function (On-Mom) must be identical.

Mechanical Parameters: Actuator type (push-pull plunger), mounting configuration (chassis mount), and termination method (solder turret) must match exactly.

Physical Parameters: Operating force (907gf), operating position (0.220" / 5.6mm), and overtravel (0.175" / 4.5mm) must be identical.

Environmental Parameters: Operating temperature range (-53°C to 121°C) and RoHS compliance status must be maintained.

The 17AC34-T is functionally equivalent to the 17AC1-T, which shares all specified electrical, mechanical, and environmental parameters while maintaining active product status.

Parameter Comparison

Engineering Selection Recommendations

The 17AC1-T is the direct functional equivalent for the obsolete 17AC34-T. Both components are manufactured by Honeywell Sensing and Productivity Solutions and share identical electrical ratings, mechanical specifications, and environmental operating parameters.

The primary distinction is product status: the 17AC34-T is obsolete, while the 17AC1-T maintains active status. This status difference ensures continued availability and supply chain support for the 17AC1-T.

Both parts maintain RoHS compliance and MSL 1 rating, confirming suitability for standard manufacturing and storage conditions without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can the 17AC1-T directly replace the 17AC34-T in existing designs?

A: Yes. The 17AC1-T shares identical electrical ratings (5A at 250V AC / 30V DC), mechanical configuration (push-pull plunger, chassis mount, solder turret termination), and operating parameters (907gf operating force, 0.220" operating position, -53°C to 121°C temperature range). Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference?

A: The 17AC34-T is classified as obsolete, indicating discontinued manufacturing and limited availability. The 17AC1-T is active, ensuring ongoing production, supply chain availability, and manufacturer support. For new designs and ongoing production, the 17AC1-T is the recommended selection.

Q: Are there packaging differences between these parts?

A: The 17AC34-T is supplied with unspecified packaging, while the 17AC1-T is supplied in bulk packaging. Both configurations are suitable for component integration; packaging selection depends on procurement and assembly requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 17AC34-T and 17AC1-T are RoHS compliant and carry MSL 1 rating, indicating unlimited shelf life without moisture sensitivity constraints. Both are classified under ECCN EAR99 and HTSUS 8536.50.7000.

Q: Are the mechanical dimensions identical?

A: Yes. Operating force (907gf), operating position (0.220" / 5.6mm), and overtravel (0.175" / 4.5mm) are identical across both parts, confirming mechanical interchangeability in chassis-mounted applications.
