Honeywell 11SM701 Snap Action Switch SPDT Equivalent & Substitute Parts

Part Overview

The Honeywell 11SM701 is an active-status snap action switch with Single Pole Double Throw (SPDT) circuit configuration, rated for 4A AC at 250V and 5A DC at 30V. This chassis-mounted switch features a round pin plunger actuator with solder lug termination and is designed for on-momentary switching applications. The part is RoHS compliant and rated for 10,000,000 mechanical cycles across an operating temperature range of -55°C to 125°C. Equivalent substitute parts are available from E-Switch when application requirements permit operation at reduced voltage or current ratings, or when alternative mechanical specifications are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Honeywell 11SM701 are identified from the E-Switch MS0850500 series based on the following substitution criteria:

Common Electrical Parameters:

• Circuit configuration: SPDT maintained across all substitutes
• Switch function: On-momentary operation preserved
• Actuator type: Round pin plunger consistent with main part
• Mounting type: Chassis mount maintained
• Termination style: Solder lug consistent
• Moisture sensitivity: MSL 1 (Unlimited) across all parts
• ECCN classification: EAR99 for all parts

Substitution Limitations: The E-Switch MS0850500 series substitutes operate at reduced voltage and current ratings compared to the Honeywell 11SM701. All three E-Switch alternatives are rated for 5A AC at 125V maximum, which represents a significant reduction from the Honeywell part's 250V AC rating. These substitutes are suitable only for applications where the lower voltage and current specifications are acceptable.

Mechanical Specification Variations: Operating force, release force, pretravel, and mechanical life differ between the main part and substitutes. The Honeywell 11SM701 provides 10,000,000 mechanical cycles, while E-Switch alternatives provide 1,000,000 cycles. Operating force ranges from 60gf to 250gf across the E-Switch variants, compared to 56gf for the Honeywell part.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The Honeywell 11SM701 remains the specified choice for applications requiring 250V AC operation, 4A AC current capacity, or extended operating temperature range (-55°C to 125°C). This part is active-status and RoHS compliant, suitable for high-reliability applications demanding extended mechanical life of 10,000,000 cycles.

Substitute Part Selection Criteria:

E-Switch MS0850500F060S1A is applicable when application voltage does not exceed 125V AC and current requirements do not exceed 5A AC. This variant provides the lowest operating force (60gf) among E-Switch alternatives and is suitable for applications requiring minimal actuation effort. Product status is active with ROHS3 compliance.

E-Switch MS0850500F080S1A is applicable for 125V AC applications at 5A AC maximum current with moderate operating force requirements (80gf). This variant maintains active product status and ROHS3 compliance. Mechanical life is rated at 1,000,000 cycles.

E-Switch MS0850500F250S1A is applicable for 125V AC applications requiring higher operating force (250gf) and release force (50gf). This variant is suitable for applications where increased actuation resistance is beneficial. Product status is active with ROHS3 compliance.

Compliance Considerations: All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating and EAR99 ECCN classification consistent with the main part. E-Switch substitutes carry ROHS3 compliance versus RoHS compliance for the Honeywell part. All parts are active-status products suitable for new designs.

Temperature and Cycle Life Trade-offs: Substitution requires acceptance of reduced operating temperature range (-25°C to 85°C versus -55°C to 125°C) and reduced mechanical life (1,000,000 cycles versus 10,000,000 cycles). These reductions must be evaluated against application requirements before substitution.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch MS0850500 series parts directly replace the Honeywell 11SM701 in all applications?

A: No. E-Switch substitutes are limited to applications operating at 125V AC maximum and 5A AC maximum current. The Honeywell 11SM701 is rated for 250V AC and 4A AC. Substitution is only valid when application voltage and current specifications fall within the E-Switch part ratings.

Q: What is the primary electrical difference between the Honeywell 11SM701 and E-Switch substitutes?

A: The Honeywell 11SM701 is rated for 250V AC operation, while all E-Switch MS0850500 series substitutes are rated for 125V AC maximum. This represents a 50% reduction in voltage rating. Current ratings are comparable (4A AC for Honeywell versus 5A AC for E-Switch).

Q: How do mechanical specifications differ between the main part and substitutes?

A: The Honeywell 11SM701 provides 10,000,000 mechanical cycles compared to 1,000,000 cycles for E-Switch substitutes. Operating force varies from 56gf (Honeywell) to 60gf, 80gf, or 250gf depending on the E-Switch variant selected. Pretravel is 0.020" for Honeywell versus 0.043" for E-Switch parts.

Q: Are all parts RoHS compliant?

A: The Honeywell 11SM701 is RoHS compliant. E-Switch MS0850500 series parts are ROHS3 compliant. Both compliance levels are acceptable for RoHS-regulated applications, with ROHS3 representing a more recent compliance standard.

Q: What is the operating temperature difference?

A: The Honeywell 11SM701 operates from -55°C to 125°C. E-Switch substitutes operate from -25°C to 85°C. This 30°C reduction at the lower end and 40°C reduction at the upper end must be evaluated against application thermal requirements.

Q: Which E-Switch variant should be selected for lowest actuation force?

A: The E-Switch MS0850500F060S1A provides the lowest operating force at 60gf, compared to 80gf for the F080S1A variant and 250gf for the F250S1A variant. Selection depends on application actuation force requirements.

Q: Are all parts available in the same packaging format?

A: All parts listed are supplied in bulk packaging. Inventory availability is confirmed for all variants: Honeywell 11SM701 (1087 pcs), E-Switch MS0850500F060S1A (997 pcs), E-Switch MS0850500F080S1A (1250 pcs), and E-Switch MS0850500F250S1A (1404 pcs).

Q: What is the electrical life rating for substitute parts?

A: E-Switch MS0850500 series parts are rated for 50,000 electrical cycles. The Honeywell 11SM701 does not specify an electrical life rating in the provided data.

Q: Can substitutes be used in applications requiring the full -55°C to 125°C temperature range?

A: No. E-Switch substitutes are limited to -25°C to 85°C operation. Applications requiring the full Honeywell temperature range must use the 11SM701 or identify alternative parts with equivalent extended temperature specifications.
