Equivalent & Substitute Parts for Honeywell 23SX39-T2

Part Overview

The Honeywell 23SX39-T2 is an active-status snap action switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 1A at 125V AC and 30V DC. This chassis-mount switch features a round pin plunger actuator and solder turret termination, designed for applications requiring momentary contact switching with defined mechanical actuation characteristics. The part is RoHS Compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when electrical specifications, mechanical parameters, circuit configuration, and mounting characteristics remain identical across alternative manufacturer part numbers within the same product series.

Key Parameters

Substitute Part Grouping Explanation

The 23SX39-T2 and 23SX39-T are direct substitutes within the Honeywell SX series. Substitution eligibility is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit type (SPDT), switch function (On-Mom), current rating (1A AC/DC), voltage ratings (125V AC / 30V DC)

Mechanical Parameters: Actuator type (Round Pin Plunger), operating force (141gf), release force (28gf), operating position (0.320"), mechanical life (1,000,000 cycles)

Physical Parameters: Mounting type (Chassis Mount), termination style (Solder Turret), operating temperature range (-53°C to 85°C)

Compliance Parameters: RoHS compliance status, MSL rating (Level 1)

Both parts share identical base product number 23SX39 and maintain full parameter alignment, confirming direct substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the 23SX39-T2 and 23SX39-T are active-status products from Honeywell Sensing and Productivity Solutions, confirming ongoing manufacturer support and availability. The 23SX39-T carries ROHS3 Compliant certification, representing an updated compliance designation relative to the 23SX39-T2's RoHS Compliant status. Both parts maintain identical electrical, mechanical, and thermal specifications.

Selection between these parts should be based on:

Compliance Requirements: If ROHS3 certification is explicitly required by procurement or regulatory specifications, the 23SX39-T is the appropriate selection. If RoHS Compliant status is sufficient, either part is acceptable.

Inventory Availability: The 23SX39-T maintains 1218 pieces in stock versus 1165 pieces for the 23SX39-T2, providing marginally higher availability.

Application Continuity: For existing designs currently using 23SX39-T2, direct substitution with 23SX39-T requires no circuit redesign, PCB modification, or functional re-qualification due to complete parameter equivalence.

Frequently Asked Questions (FAQ)

Q: Can 23SX39-T replace 23SX39-T2 in existing applications?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The 23SX39-T can be directly substituted in any application currently using 23SX39-T2 without circuit modification or performance impact.

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

A: ROHS3 represents an updated compliance designation reflecting current regulatory standards. Both designations confirm the part meets RoHS requirements. The 23SX39-T carries the more current ROHS3 designation.

Q: Are the mechanical actuation characteristics identical?

A: Yes. Operating force (141gf), release force (28gf), operating position (0.320"), pretravel, differential travel, and overtravel specifications are identical between both parts.

Q: What is the rated electrical performance?

A: Both parts are rated for 1A at 125V AC or 30V DC with SPDT momentary contact switching. Mechanical life is specified at 1,000,000 cycles.

Q: Are there packaging differences?

A: Both parts are supplied in Bulk packaging. No packaging format differences exist between the two part numbers.

Q: What is the operating temperature range?

A: Both parts operate across -53°C to 85°C, with identical thermal performance characteristics.

Q: Is the 23SX39-T suitable for high-reliability applications?

A: Both parts carry MSL Level 1 (Unlimited) moisture sensitivity rating and are RoHS/ROHS3 compliant, supporting use in controlled manufacturing environments. Specific application reliability requirements should be evaluated against the provided mechanical life specification of 1,000,000 cycles.
