Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5-435166-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit type must remain SPST
• Position count must equal 8
• Current rating must support minimum 25mA
• Voltage rating must support 24VDC operation

Mechanical Compatibility Requirements:

• Actuator type must be rocker configuration
• Mounting method must be through-hole
• Termination must be PC pin style
• Pitch spacing must be 0.100" (2.54mm)
• Sealed and washable characteristics must be maintained

Environmental Requirements:

• Operating temperature range must encompass -55°C to 105°C
• Series designation must be 7000

The substitute part 5-5435166-3 satisfies all mandatory electrical and mechanical parameters, enabling direct functional replacement in applications currently utilizing the obsolete 5-435166-3.

Parameter Comparison

Engineering Selection Recommendations

The 5-5435166-3 serves as the direct functional equivalent for the obsolete 5-435166-3 based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active manufacturing status, ensuring long-term availability and supply chain continuity. The obsolete status of the original part creates procurement risk for ongoing production and field service applications.

Compliance Certification: The 5-5435166-3 achieves ROHS3 compliance, whereas the original part is non-compliant. For applications subject to RoHS regulatory requirements, the substitute part satisfies mandatory environmental standards. The original part remains suitable for applications where RoHS compliance is not required.

Electrical and Mechanical Equivalence: Both parts share identical circuit configuration (SPST), position count (8), actuator type (rocker), mounting method (through-hole), and sealed/washable characteristics. The substitute part maintains the 7000 series designation and core functional specifications.

Packaging Consideration: The substitute part is supplied in Tape & Reel format, whereas the original part is supplied in bulk packaging. Design and procurement workflows must accommodate this packaging difference for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 5-5435166-3 directly replace the 5-435166-3 in existing circuit board designs?

A: Yes. Both parts share identical electrical specifications (SPST, 8-position, 25mA, 24VDC), actuator type (rocker), mounting method (through-hole), and mechanical dimensions. No circuit board redesign is required for substitution.

Q: What is the primary reason for substituting the 5-435166-3?

A: The original part carries obsolete product status, creating supply chain risk. The 5-5435166-3 is an active product with current manufacturing support and improved RoHS3 compliance certification.

Q: Are there electrical performance differences between these parts?

A: No. Both parts operate at identical current (25mA) and voltage (24VDC) ratings within the same temperature range (-55°C to 105°C). Electrical performance is equivalent.

Q: Does the packaging change from bulk to Tape & Reel affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. The change impacts procurement, storage, and assembly process workflows. Tape & Reel format is standard for automated pick-and-place assembly operations.

Q: Is the 5-5435166-3 suitable for applications requiring RoHS compliance?

A: Yes. The 5-5435166-3 is ROHS3 compliant. The original 5-435166-3 is non-compliant and unsuitable for applications with RoHS regulatory requirements.

Q: What parameters must remain identical for substitution to be valid?

A: Circuit configuration (SPST), position count (8), actuator type (rocker), mounting method (through-hole), pitch spacing (0.100"), sealed/washable characteristics, and operating temperature range (-55°C to 105°C) must all remain identical. These parameters define functional equivalence.

Q: Can the 5-5435166-3 be used in legacy equipment designed for the 5-435166-3?

A: Yes. The substitute part maintains all mechanical and electrical specifications required for direct replacement in legacy applications. No modifications to equipment or circuitry are necessary.
