Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Rocker Actuator Required):

Part number 9-435626-2 serves as the direct equivalent to 4-435626-2. Both components maintain identical electrical specifications, mechanical dimensions, and actuator configuration. The primary distinction is packaging format (tube versus unspecified) and regulatory compliance status. Part 9-435626-2 achieves ROHS3 compliance, whereas the main part is RoHS non-compliant. Selection of 9-435626-2 is appropriate for applications requiring rocker actuator functionality with modern compliance requirements.

For Functional Substitution (Actuator Type Flexibility):

Part number 1-1825006-3 provides electrical equivalence with alternative actuator configuration (slide type). This component is classified as active product status, ensuring long-term availability and supply chain continuity. The 1-1825006-3 achieves ROHS3 compliance and REACH unaffected status. Physical profile differences include reduced height above board (0.114" versus 0.290") and shorter overall length (0.794" versus 0.880"), enabling use in space-constrained applications.

Compliance Considerations:

Applications subject to RoHS3 or REACH regulatory requirements must utilize either 9-435626-2 or 1-1825006-3. The main part 4-435626-2 does not meet current regulatory standards. Part 1-1825006-3 offers the most favorable compliance posture with active product status and REACH unaffected classification.

Operational Temperature Limitations:

Part 1-1825006-3 operates within -30°C to 85°C range, compared to -55°C to 105°C for the main part and direct equivalent. Applications requiring extended temperature operation below -30°C or above 85°C must utilize 4-435626-2 or 9-435626-2.

Mechanical Life Considerations:

Part 1-1825006-3 specifies 1,000 mechanical and electrical cycles, whereas the main part and direct equivalent specify 7,000 cycles. Applications with high cycle count requirements must utilize 4-435626-2 or 9-435626-2.

Frequently Asked Questions (FAQ)

Q: Can 9-435626-2 directly replace 4-435626-2 in existing designs?

A: Yes. Part 9-435626-2 maintains identical electrical ratings (25mA, 24VDC, SPST, 8-position), mechanical dimensions, actuator type (rocker), mounting method (through hole), and termination style (PC pin). The components are mechanically and electrically interchangeable. Packaging format differs (tube versus unspecified), and 9-435626-2 achieves ROHS3 compliance.

Q: What are the key differences between rocker actuator (4-435626-2, 9-435626-2) and slide actuator (1-1825006-3) configurations?

A: Rocker actuators feature a pivoting lever mechanism with 0.290" height above board. Slide actuators use a linear sliding mechanism with 0.114" height above board. Both provide identical electrical switching function (SPST, 8-position, 25mA, 24VDC). Slide actuator configuration enables installation in applications with vertical space constraints. Rocker actuators provide tactile feedback and are suitable for manual configuration applications.

Q: Is 1-1825006-3 suitable for applications requiring -55°C operation?

A: No. Part 1-1825006-3 operates within -30°C to 85°C range. Applications requiring operation below -30°C must utilize 4-435626-2 or 9-435626-2, which operate from -55°C to 105°C.

Q: What is the mechanical life difference between substitute options?

A: Parts 4-435626-2 and 9-435626-2 specify 7,000 mechanical cycles. Part 1-1825006-3 specifies 1,000 mechanical cycles. Applications with cycle counts exceeding 1,000 operations require rocker actuator variants (4-435626-2 or 9-435626-2).

Q: Which substitute part offers the best long-term availability?

A: Part 1-1825006-3 is classified as active product status, indicating ongoing manufacturing and supply chain support. Parts 4-435626-2 and 9-435626-2 are classified as obsolete, indicating limited future availability. For new designs or long-term procurement planning, 1-1825006-3 is the preferred selection where operational requirements permit slide actuator configuration and reduced mechanical cycle rating.

Q: Are all substitute parts RoHS compliant?

A: Part 4-435626-2 is RoHS non-compliant. Parts 9-435626-2 and 1-1825006-3 are ROHS3 compliant. Applications subject to RoHS regulatory requirements must utilize 9-435626-2 or 1-1825006-3.

Q: What is the physical footprint difference between rocker and slide actuator variants?

A: Rocker actuator parts (4-435626-2, 9-435626-2) measure 0.880" length and 0.290" height above board. Slide actuator part (1-1825006-3) measures 0.794" length and 0.114" height above board. The slide variant provides 0.176" reduction in height and 0.086" reduction in length, enabling installation in compact PCB layouts.

Q: Can 1-1825006-3 be used in applications designed for rocker actuator operation?

A: Electrical and mechanical substitution is valid. However, user interface differences exist. Rocker actuators provide pivoting lever operation suitable for manual configuration. Slide actuators require linear sliding motion. Application design must accommodate actuator type difference. Physical profile reduction (height and length) may enable installation in space-constrained applications where rocker variants cannot fit.
