Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-1825033-1 rotary DIP switch is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Hexadecimal circuit configuration (16 positions)
• Current rating of 0.4VA
• Voltage rating of 20VAC/DC
• Rotary actuator with shaft actuation mechanism
• Copper alloy contacts with gold finish
• Through-hole mounting capability
• PC pin termination style
• 0.100" (2.54mm) pitch spacing
• Operating temperature range of -30°C to 85°C
• Mechanical and electrical life of 20,000 steps
• Polyphenylene Sulfide (PPS) body material

The substitute part 1825008-8 satisfies all mandatory matching parameters. The primary distinction between the main part and the substitute involves mounting orientation (standard vertical versus right-angle configuration) and physical height above the board, which represent geometric variations rather than functional or electrical differences. Both components maintain identical electrical specifications, contact materials, and operational characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 1825008-8 represents the manufacturer-recommended substitute for the obsolete 1-1825033-1 rotary DIP switch. Selection of the 1825008-8 is supported by the following engineering considerations:

Product Status: The 1-1825033-1 carries obsolete status, indicating discontinued manufacturing and limited availability. The 1825008-8 maintains active product status with current manufacturing support and documented inventory availability.

Regulatory Compliance: The 1825008-8 is ROHS3 compliant and carries REACH Unaffected status, meeting current environmental and regulatory requirements. The original 1-1825033-1 does not carry defined compliance certifications.

Electrical and Functional Equivalence: Both components operate identically across all critical electrical parameters: hexadecimal 16-position configuration, 0.4VA current rating, 20VAC/DC voltage rating, and identical mechanical and electrical life specifications of 20,000 steps.

Geometric Considerations: The 1825008-8 features right-angle mounting orientation with a height above board of 0.413" (10.50mm), compared to the standard vertical mounting of the 1-1825033-1 at 0.543" (13.80mm). PCB layout and mechanical clearance requirements must be evaluated to determine mounting orientation compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1825008-8 directly replace the 1-1825033-1 in all applications?

A: The 1825008-8 provides electrical and functional equivalence to the 1-1825033-1 across all specified parameters. However, the right-angle mounting configuration of the 1825008-8 differs from the standard vertical mounting of the original part. PCB layout, available board space, and mechanical clearance requirements must be evaluated to confirm physical compatibility.

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

A: The primary difference is mounting orientation. The 1-1825033-1 uses standard through-hole vertical mounting, while the 1825008-8 uses right-angle through-hole mounting. This results in different heights above the board: 0.543" (13.80mm) for the 1-1825033-1 and 0.413" (10.50mm) for the 1825008-8. All electrical specifications remain identical.

Q: Why is the 1-1825033-1 listed as obsolete?

A: The 1-1825033-1 carries obsolete product status, indicating that TE Connectivity has discontinued manufacturing. The 1825008-8 is the active equivalent offering from the same manufacturer and series, providing continued availability and support.

Q: Are there any compliance differences between these parts?

A: Yes. The 1825008-8 is ROHS3 compliant and carries REACH Unaffected status. The 1-1825033-1 does not have defined compliance certifications. For applications requiring regulatory compliance documentation, the 1825008-8 is the appropriate selection.

Q: What packaging is available for the 1825008-8?

A: The 1825008-8 is supplied in tube packaging. The original 1-1825033-1 packaging specification was not defined in the available documentation.

Q: Do both parts use the same contact materials and finishes?

A: Yes. Both the 1-1825033-1 and 1825008-8 utilize copper alloy contacts with gold finish, ensuring equivalent electrical performance and contact reliability.

Q: Are the pitch and termination specifications identical?

A: Yes. Both components feature 0.100" (2.54mm) full pitch spacing and PC pin termination style, ensuring compatibility with standard DIP switch footprints and PCB designs.
