SSCEA31C Equivalent & Substitute Parts Reference

Part Overview

The SSCEA31C is a snap-action switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a single-pole double-throw (SPDT) device with chassis mount installation. This component operates at 120V AC / 125V DC with a 600mA AC current rating and features a roller plunger actuator with cable lead termination. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSCEA31C is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT), switch function (On-Momentary), current rating (600mA AC / 220mA DC), and voltage ratings (120V AC / 125V DC) must be identical.

Mechanical Parameters: Actuator type (Roller Plunger), mounting type (Chassis Mount), and termination style (Cable Leads) must match exactly.

Environmental Parameters: Ingress protection rating (IP68), operating temperature range (-40°C to 90°C), and mechanical life (10,000,000 cycles) must be maintained.

Compliance Parameters: RoHS compliance status must be equivalent or superior.

The SSCEB31C meets all substitution criteria as a functionally equivalent alternative within the SSCE series.

Parameter Comparison

Engineering Selection Recommendations

The SSCEB31C is a direct functional equivalent to the SSCEA31C across all electrical, mechanical, and environmental specifications. The primary distinction is product status: SSCEA31C is classified as obsolete while SSCEB31C maintains active status within the Honeywell product line.

Both components are RoHS compliant and manufactured by the same supplier within the same SSCE series. The SSCEB31C is available in bulk packaging with confirmed inventory of 1,066 units, whereas the SSCEA31C is available in original packaging with 810 units in stock.

For new designs or system replacements, the SSCEB31C is the appropriate selection due to its active product status and assured long-term availability. For legacy system maintenance where original part specifications must be preserved, the SSCEA31C remains functionally suitable if inventory permits.

Frequently Asked Questions (FAQ)

Q: Can SSCEB31C directly replace SSCEA31C in existing installations?

A: Yes. The SSCEB31C is electrically and mechanically identical to the SSCEA31C. All electrical ratings (600mA AC, 220mA DC, 120V AC, 125V DC), mechanical specifications (roller plunger actuator, chassis mount, cable leads), and environmental parameters (IP68, -40°C to 90°C operating range) are equivalent. Direct substitution is supported without circuit modification.

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

A: SSCEA31C is classified as obsolete, indicating Honeywell has discontinued active production and support. SSCEB31C maintains active status, ensuring continued availability, technical support, and compliance with current manufacturing standards. For procurement planning, the active status of SSCEB31C provides supply chain stability.

Q: Are there packaging differences between these parts?

A: Yes. SSCEA31C is supplied in original packaging, while SSCEB31C is supplied in bulk packaging. Both configurations contain identical components with identical electrical and mechanical properties. Packaging selection depends on inventory management and application requirements.

Q: Do both parts meet current compliance requirements?

A: Yes. Both SSCEA31C and SSCEB31C are RoHS compliant. Moisture sensitivity level for both is MSL 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: What are the key mechanical specifications that define substitution eligibility?

A: Operating force (1200gf), release force (450gf), operating position (28.5mm), pretravel (1.0mm), differential travel (0.1mm), and overtravel (3.0mm) must remain constant. Both parts maintain identical mechanical specifications, confirming full substitution compatibility.

Q: Is the 3-meter cable length a fixed specification?

A: Yes. Both SSCEA31C and SSCEB31C include 3-meter cable leads as a standard feature. This specification is identical across both parts.
