Key Parameters

Substitute Part Grouping Explanation

Substitution of the 436860-7 with the 1825190-7 is based on functional and mechanical equivalence across the following critical parameters:

Functional Equivalence:

• Both components provide 8-position programmable DIP switch functionality
• Both utilize breakable shunt actuator technology
• Both maintain flush, recessed actuator positioning
• Both support programmable circuit configuration

Mechanical Compatibility:

• Identical pitch specification: 0.100" (2.54mm), Full
• Identical length: 0.800" (20.32mm)
• Both employ through-hole mounting with PC pin termination
• Both feature washable construction

Contact and Material Specifications:

• Both utilize tin-plated contact finish
• Both employ thermoplastic or polyester body materials suitable for DIP switch applications

The primary differences between these parts relate to product status (obsolete versus active), height above board, contact material composition, and compliance certifications, which do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The 1825190-7 serves as the direct active equivalent for the obsolete 436860-7 based on the following engineering criteria:

Product Status Consideration: The 436860-7 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 1825190-7 maintains active product status with confirmed inventory availability, ensuring supply chain continuity for new designs and production requirements.

Compliance and Certification: The 1825190-7 achieves ROHS3 compliance, meeting current regulatory requirements for electronic components in regulated markets. The 436860-7 is RoHS non-compliant, which may restrict its use in applications subject to RoHS directives.

Functional Equivalence: Both components maintain identical 8-position programmable DIP switch functionality with breakable shunt actuators, flush recessed positioning, and standard 0.100" pitch through-hole mounting. The mechanical and electrical interface characteristics remain consistent between the two parts.

Height Consideration: The 1825190-7 provides a reduced height above board of 0.079" (2.00mm) compared to the 436860-7 at 0.125" (3.17mm). This dimensional difference requires verification against specific PCB layout constraints and clearance requirements in the target application.

Temperature Rating: The 1825190-7 specifies an operating temperature range of -55°C to 105°C, whereas the 436860-7 does not provide temperature specifications. Applications requiring defined thermal performance should reference the 1825190-7 datasheet for confirmation of suitability.
