TE Connectivity ALCOSWITCH 435470-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH 435470-3 is a DIP switch with SPDT circuit configuration, rocker actuator, and 4-position through-hole design rated for 25mA at 24VDC. This component belongs to the 7000 series and is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 435470-3 is based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Voltage Rating: 24VDC
• Current Rating: 25mA
• Mounting Type: Through Hole
• Pitch: 0.100" (2.54mm)
• Termination Style: PC Pin
• Contact Material: Copper Alloy with Gold Finish

Secondary Considerations:

• Circuit configuration (SPDT or SPST)
• Number of positions
• Actuator type and height
• Operating temperature range
• Product status and compliance certifications

The substitute parts listed maintain the core electrical specifications (voltage, current, and termination compatibility) while offering variations in circuit configuration, position count, and actuator design. These variations allow for functional replacement in applications where the specific actuator type or position count is not a critical constraint.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Series): The 5-435470-3 is the direct manufacturer equivalent within the 7000 series. This part maintains SPDT circuit configuration and through-hole mounting with 0.100" pitch compatibility. The 5-435470-3 is classified as Active product status with ROHS3 compliance, addressing the obsolescence of the original 435470-3. This part is recommended when design constraints permit an increase from 4 positions to 8 positions and when a standard actuator is acceptable in place of the rocker actuator.

For Cross-Series Substitution: The 1-1825006-3 from the GDS series provides an alternative solution with active product status and ROHS3 compliance. This part maintains the 25mA/24VDC electrical specifications and through-hole mounting with 0.100" pitch. The circuit configuration differs (SPST instead of SPDT), and the actuator type is slide-based rather than rocker. The operating temperature range is reduced to -30°C to 85°C. This part is suitable for applications where SPST functionality is acceptable and the reduced temperature range does not conflict with system requirements.

Compliance Considerations: Both substitute parts are ROHS3 compliant, addressing regulatory requirements that the original obsolete part does not meet. The 1-1825006-3 is REACH unaffected, while the 5-435470-3 has undefined REACH status. For applications requiring specific environmental compliance certifications, the 1-1825006-3 provides the most comprehensive compliance profile.

Frequently Asked Questions (FAQ)

Q: Can the 5-435470-3 be used as a direct replacement for the 435470-3?

A: The 5-435470-3 maintains electrical compatibility (SPDT circuit, through-hole mounting, 0.100" pitch) and is from the same 7000 series. The primary differences are increased position count (8 vs. 4) and actuator type (standard vs. rocker). Substitution is valid when the application does not require the specific rocker actuator profile or when the additional positions provide design flexibility.

Q: What are the key differences between the 5-435470-3 and 1-1825006-3?

A: The 5-435470-3 maintains SPDT circuit configuration within the 7000 series, while the 1-1825006-3 uses SPST circuit configuration from the GDS series. The 1-1825006-3 features a slide actuator with flush profile (0.114" height) compared to the raised rocker profile of the 435470-3 (0.360" height). Operating temperature ranges differ: 435470-3 operates -55°C to 105°C, while 1-1825006-3 operates -30°C to 85°C. Both maintain 25mA/24VDC ratings and 0.100" pitch through-hole mounting.

Q: Are there packaging differences between these parts?

A: Yes. The 435470-3 is supplied in standard packaging (not specified). The 5-435470-3 is supplied in bulk packaging. The 1-1825006-3 is supplied in tube packaging with tape seal feature. Packaging selection depends on production volume requirements and handling procedures.

Q: Which substitute part is recommended for new designs?

A: For new designs requiring SPDT functionality with rocker actuator, the 5-435470-3 is the preferred choice as it maintains the same circuit type and series lineage. For designs where SPST functionality is acceptable and compact profile is advantageous, the 1-1825006-3 offers active product status with comprehensive compliance certifications.

Q: What is the impact of the reduced operating temperature range in the 1-1825006-3?

A: The 1-1825006-3 operates from -30°C to 85°C, compared to the 435470-3 range of -55°C to 105°C. This represents a reduction of 25°C at the low end and 20°C at the high end. Substitution is valid only for applications where the component operates within the -30°C to 85°C range.

Q: Are the mechanical life specifications comparable?

A: The 435470-3 specifies 7,000 mechanical cycles. The 1-1825006-3 specifies 1,000 mechanical cycles. For applications requiring frequent actuation, the 435470-3 or 5-435470-3 provide superior mechanical durability.

Q: What is the washable characteristic difference?

A: The 435470-3 and 5-435470-3 are not washable. The 1-1825006-3 is washable with tape seal feature, allowing for aqueous cleaning processes during PCB assembly. This distinction is relevant for manufacturing processes that include post-assembly cleaning steps.
