SSB12G Equivalent & Substitute Parts

Part Overview

The SSB12G is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Single Pole Double Throw (SPDT) switch with a rated capacity of 0.4VA at 20V. This component features through-hole mounting with gold-plated copper alloy contacts and is designed for On-On switching applications with make-before-break (MBB) contact timing.

The SSB12G carries an Obsolete product status. Identification of equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this switch type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSB12G with equivalent parts is determined by strict alignment of the following critical electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Contact timing must be Shorting (MBB)
• Switch function must be On-On
• Current rating must be 0.4VA (AC/DC)
• Voltage ratings must be 20V (both AC and DC)

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Termination style must be PC Pin
• Contact material must be Copper Alloy with Gold finish
• Actuator material must be Polyoxymethylene (Acetal) (POM)
• Switch travel must be 2.00mm
• Operating temperature range must be -20°C to 85°C

The substitute part 1825257-2 satisfies all critical electrical and mechanical parameters required for functional equivalence. Differences in actuator length, mechanical life, operating force, and electrical life do not prevent substitution when the primary switching characteristics and physical mounting requirements are identical.

Parameter Comparison

Engineering Selection Recommendations

The 1825257-2 is a direct functional equivalent to the SSB12G for applications requiring SPDT slide switch operation at 0.4VA and 20V ratings with through-hole PC pin termination.

Product Status Consideration: The SSB12G is classified as Obsolete, while the 1825257-2 is Active. Selection of the 1825257-2 ensures access to current manufacturing stock and ongoing supplier support.

Compliance and Certification: The 1825257-2 carries ROHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs and production environments subject to RoHS requirements. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications, indicating equivalent export and tariff treatment.

Physical and Electrical Performance: All critical electrical parameters (voltage, current, circuit configuration, contact timing) are identical between the two parts. The switch travel distance of 2.00mm is maintained, ensuring mechanical compatibility with existing PCB layouts and mechanical assemblies designed for the SSB12G.

Secondary Parameter Differences: The 1825257-2 exhibits higher mechanical life (15,000 cycles versus 10,000 cycles) and documented electrical life (15,000 cycles), representing improved durability characteristics. The actuator length difference (5.00mm versus 1.09mm) and increased operating force (600gf versus 250gf) must be evaluated against specific mechanical design constraints and user interface requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 1825257-2 be used as a direct replacement for the SSB12G in existing designs?

A: The 1825257-2 is electrically and functionally equivalent to the SSB12G for all switching operations. The primary consideration is the actuator length difference (5.00mm versus 1.09mm). If the existing mechanical design accommodates or requires a longer actuator, direct substitution is valid. If the design space is constrained to the original 1.09mm actuator length, mechanical redesign or alternative parts must be evaluated.

Q: What is the significance of the operating force difference between these parts?

A: The SSB12G requires 250gf operating force, while the 1825257-2 requires 600gf. This difference affects the tactile feedback and effort required to actuate the switch. Applications with user interface requirements for minimal actuation force should account for this 350gf increase. Applications with mechanical actuation or automated switching may require force analysis to ensure adequate actuation capability.

Q: Are there any compliance or regulatory differences between the SSB12G and 1825257-2?

A: The 1825257-2 is ROHS3 compliant, while the SSB12G compliance status is not specified. Both parts share identical ECCN and HTSUS classifications. For applications subject to RoHS requirements, the 1825257-2 provides documented compliance. For export or tariff purposes, both parts are treated identically.

Q: Does the higher mechanical life rating of the 1825257-2 affect substitution decisions?

A: The 1825257-2 offers 15,000 mechanical cycles compared to the SSB12G's 10,000 cycles. This represents improved durability and extended service life. For applications with high cycle count requirements or extended operational life expectations, the 1825257-2 provides enhanced performance. For applications within the 10,000-cycle range, both parts are functionally equivalent.

Q: What packaging differences exist between these parts?

A: The SSB12G is supplied in unspecified packaging, while the 1825257-2 is supplied in Bulk packaging. Bulk packaging typically indicates standard reel or tape formats suitable for automated assembly processes. Packaging selection should align with production methodology and component handling requirements.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the SSB12G and 1825257-2 operate across the identical temperature range of -20°C to 85°C. No thermal performance differentiation exists between these parts.
