DA105-PB-B Toggle Switch SPST Equivalent & Substitute Parts

Part Overview

The DA105-PB-B is an active production toggle switch manufactured by Carling Technologies, designed for panel-mount applications requiring single-pole, single-throw (SPST) switching functionality. This component operates at 10A AC at 125V with a non-illuminated paddle actuator and wire lead termination. The part is ROHS3 compliant and REACH unaffected, making it suitable for regulated applications.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges, allowing for component availability optimization and supply chain flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DA105-PB-B are identified based on the following electrical and mechanical compatibility criteria:

Electrical Compatibility Requirements:

• Circuit configuration must be SPST
• Voltage rating must be 125V AC
• Current rating must be 10A AC or greater
• Switch function must be On-Off

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount
• Panel cutout diameter must accommodate circular mounting within acceptable tolerance
• Termination style must be compatible with application requirements

Regulatory and Environmental Requirements:

• RoHS3 compliance status must be maintained
• Operating temperature range must support the intended application environment

The substitute part 4631A22UU from APEM Inc. is evaluated against these criteria to determine functional equivalence and substitutability.

Parameter Comparison

Engineering Selection Recommendations

DA105-PB-B (Primary Component): The DA105-PB-B remains the specified component for applications requiring the full rated current capacity of 10A AC, extended electrical life of 25,000 cycles, and the complete operating temperature range of 0°C to 85°C. This component is active in production with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment and supply continuity.

4631A22UU (Substitute Component): The 4631A22UU from APEM Inc. provides functional equivalence for SPST 125V AC switching applications where the following conditions are met:

• Application current requirements do not exceed 6A AC
• Electrical cycle life requirement does not exceed 10,000 cycles
• Operating temperature environment remains within -20°C to 55°C
• Termination compatibility with solder or quick connect 0.110" (2.8mm) terminals is acceptable
• Panel cutout diameter tolerance accommodates 12.20mm circular mounting

Both components maintain ROHS3 compliance and REACH unaffected status. Selection between these components depends on specific application electrical and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the 4631A22UU directly replace the DA105-PB-B in all applications?

A: No. The 4631A22UU has a lower current rating (6A versus 10A), reduced electrical life (10,000 versus 25,000 cycles), and a narrower operating temperature range (-20°C to 55°C versus 0°C to 85°C). Substitution is valid only when application requirements fall within the 4631A22UU specifications.

Q: What is the primary difference in termination between these two parts?

A: The DA105-PB-B uses wire leads for termination, while the 4631A22UU provides solder or quick connect 0.110" (2.8mm) termination options. Application circuit board design and assembly methods determine termination compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the DA105-PB-B and 4631A22UU are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in regulated markets.

Q: How do the panel cutout dimensions compare?

A: The DA105-PB-B requires a 12.70mm circular cutout, while the 4631A22UU requires a 12.20mm circular cutout. Panel mounting compatibility depends on the specific panel design and tolerance specifications.

Q: What electrical life difference exists between these components?

A: The DA105-PB-B is rated for 25,000 electrical cycles, while the 4631A22UU is rated for 10,000 cycles. Applications with high switching frequency or extended operational life requirements should use the DA105-PB-B.

Q: Which component supports the wider operating temperature range?

A: The DA105-PB-B operates from 0°C to 85°C, providing a wider temperature envelope than the 4631A22UU, which operates from -20°C to 55°C. Applications in elevated temperature environments require the DA105-PB-B.
