SSB12R Equivalent & Substitute Parts

Part Overview

The SSB12R 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. This component features a through-hole, right-angle mounting configuration with PC pin termination and epoxy sealed terminals. The SSB12R 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 components for the SSB12R are identified based on electrical and mechanical compatibility within the specified parameters. The primary substitution criteria include:

Electrical Parameters: Circuit configuration (SPDT), contact timing (Shorting/MBB), current rating (100mA DC), and voltage rating (30V) must be identical to ensure functional equivalence in the application circuit.

Mechanical Parameters: Mounting type (through hole, right angle), termination style (PC pin), and switch travel (2.00mm) must match to ensure physical compatibility with the printed circuit board layout and mechanical assembly requirements.

Contact Material and Finish: While contact material may vary between copper alloy and phosphor bronze, both with silver finish provide equivalent electrical performance within the specified current and voltage ratings.

Actuator Configuration: Standard actuator type with switch function On-On is required; however, actuator length and material may vary provided the switch travel remains constant at 2.00mm.

The SS12SBH2 manufactured by NKK Switches meets all mandatory electrical and mechanical substitution criteria for the SSB12R.

Parameter Comparison

Engineering Selection Recommendations

The SS12SBH2 from NKK Switches is a direct functional substitute for the obsolete SSB12R. Both components share identical electrical specifications (SPDT circuit, 100mA DC at 30V, shorting contact timing) and mechanical compatibility (through-hole right-angle mounting, PC pin termination, 2.00mm switch travel, 10,000 cycle mechanical life).

The SS12SBH2 is classified as an active product with ROHS3 compliance and MSL 1 rating, providing superior long-term availability and regulatory compliance compared to the obsolete SSB12R. Both components maintain REACH Unaffected status and EAR99 export classification.

Variations in actuator length (4.29mm versus 2.50mm), actuator material (POM versus polyamide), and operating temperature range (-20°C to 85°C versus -15°C to 60°C) do not affect substitution validity when the application operates within the SS12SBH2 specifications. PCB layout and mechanical assembly must accommodate the reduced actuator length of the SS12SBH2.

Frequently Asked Questions (FAQ)

Q: Can the SS12SBH2 be used as a direct replacement for the SSB12R in existing designs?

A: The SS12SBH2 provides electrical and mechanical equivalence for the SSB12R within the specified parameters. Physical board layout must be verified to accommodate the 1.79mm difference in actuator length (4.29mm versus 2.50mm). If the actuator length is not a constraint in the mechanical assembly, substitution is valid.

Q: What are the critical parameters that must match for substitution?

A: Circuit configuration (SPDT), contact timing (shorting/MBB), current rating (100mA DC), voltage rating (30V), switch function (On-On), mounting type (through hole, right angle), termination style (PC pin), and switch travel (2.00mm) must be identical. These parameters ensure functional and physical compatibility.

Q: Does the difference in contact material between copper alloy and phosphor bronze affect performance?

A: Both copper alloy and phosphor bronze with silver finish provide equivalent electrical performance within the specified 100mA DC and 30V rating. Contact material selection does not impact substitution validity for this application.

Q: What is the significance of the operating temperature range difference?

A: The SSB12R operates from -20°C to 85°C, while the SS12SBH2 operates from -15°C to 60°C. If the application requires operation below -15°C or above 60°C, the SS12SBH2 is not suitable. For applications within the -15°C to 60°C range, both components are equivalent.

Q: Why is the SS12SBH2 preferred over the SSB12R?

A: The SS12SBH2 is an active product with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and regulatory compliance. The SSB12R is obsolete, making future procurement difficult. The SS12SBH2 provides equivalent functionality with superior supply chain reliability.

Q: Are there packaging differences between the SSB12R and SS12SBH2?

A: The SSB12R is supplied with standard packaging, while the SS12SBH2 is supplied in trays. Packaging format does not affect electrical or mechanical compatibility; it impacts only logistics and handling procedures.

Q: What certifications and compliance standards apply to both components?

A: Both the SSB12R and SS12SBH2 maintain REACH Unaffected status and EAR99 export classification. The SS12SBH2 additionally carries ROHS3 compliance certification, providing enhanced regulatory alignment for modern applications.
