SSB12 Equivalent & Substitute Parts

Part Overview

The SSB12 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Single Pole Double Throw (SPDT) switch with a 100mA DC current rating at 30V. The switch features through-hole mounting with PC pin termination and is designed for On-On switching applications with shorting contact timing (Make-Before-Break). The SSB12 is classified as an obsolete product, necessitating identification of equivalent substitute components for ongoing design requirements and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSB12 are identified based on electrical and mechanical compatibility within the following critical parameters:

Electrical Compatibility Criteria:

• Circuit configuration must be SPDT
• Contact timing must be Shorting (MBB)
• Switch function must be On-On
• Current rating must support minimum 100mA DC
• Voltage rating must support minimum 30V DC

Mechanical Compatibility Criteria:

• Mounting type must be Through Hole
• Termination style must be PC Pin
• Switch travel must be 2.00mm
• Mechanical life must meet or exceed 10,000 cycles

The SS12SBP2 manufactured by NKK Switches satisfies all electrical and mechanical compatibility requirements for direct substitution with the SSB12.

Parameter Comparison

Engineering Selection Recommendations

The SS12SBP2 from NKK Switches is a direct electrical and mechanical equivalent to the obsolete SSB12. Selection of the SS12SBP2 is supported by the following factors:

Product Status: The SS12SBP2 maintains Active product status, ensuring ongoing availability and manufacturer support, whereas the SSB12 is classified as Obsolete.

Regulatory Compliance: Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99), confirming equivalent regulatory standing. The SS12SBP2 carries RoHS3 compliance certification, providing additional environmental compliance assurance.

Electrical Performance: All critical electrical parameters are identical, including circuit configuration (SPDT), contact timing (Shorting MBB), current rating (100mA DC), and voltage rating (30V DC).

Mechanical Performance: Mechanical specifications are fully aligned, with matching switch travel (2.00mm), mechanical life rating (10,000 cycles), and mounting/termination characteristics (Through Hole, PC Pin).

Material Variations: Contact material differs (Copper Alloy versus Phosphor Bronze) and actuator material differs (POM versus Polyamide/Nylon). Both material combinations are functionally equivalent for the specified electrical and mechanical operating parameters.

Inventory Availability: The SS12SBP2 is available in significantly higher inventory quantities (7,933 pieces) compared to the SSB12 (767 pieces), supporting procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can the SS12SBP2 directly replace the SSB12 in existing designs?

A: Yes. The SS12SBP2 meets all electrical and mechanical compatibility requirements for direct substitution. Both components share identical circuit configuration (SPDT), contact timing (Shorting MBB), current rating (100mA DC), voltage rating (30V DC), switch travel (2.00mm), and mounting characteristics (Through Hole PC Pin).

Q: What are the differences between the SSB12 and SS12SBP2?

A: The primary differences are product status (Obsolete versus Active), contact material (Copper Alloy versus Phosphor Bronze), and actuator material (POM versus Polyamide/Nylon). Operating temperature ranges also differ (SSB12: -20°C to 85°C; SS12SBP2: -15°C to 60°C). These differences do not affect functional compatibility for the specified electrical and mechanical parameters.

Q: Are there packaging differences between these components?

A: Yes. The SSB12 is supplied with standard packaging, while the SS12SBP2 is supplied in Tray packaging. PCB layout and mounting procedures remain identical due to matching PC Pin termination and Through Hole mounting specifications.

Q: Does the SS12SBP2 meet the same regulatory requirements as the SSB12?

A: Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99) and identical HTSUS codes (8536.50.9050). The SS12SBP2 additionally carries RoHS3 compliance certification.

Q: What is the operating temperature range for the SS12SBP2?

A: The SS12SBP2 operates across -15°C to 60°C. This range is narrower than the SSB12 (-20°C to 85°C). Verify that application operating conditions fall within the SS12SBP2 temperature specification before substitution.

Q: Are the mechanical life ratings equivalent?

A: Yes. Both the SSB12 and SS12SBP2 are rated for 10,000 mechanical cycles, providing equivalent durability for switching applications.

Q: What is the difference in contact material, and does it affect performance?

A: The SSB12 uses Copper Alloy contacts while the SS12SBP2 uses Phosphor Bronze contacts. Both materials are silver-finished and functionally equivalent for the specified 100mA DC / 30V DC electrical parameters.
