Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5435640-1 is evaluated based on the following critical parameters that determine functional and mechanical compatibility:

Mandatory Compatibility Parameters:

• Circuit Configuration: SPST topology must be maintained
• Number of Positions: 7-position requirement must be preserved
• Mounting Type: Through-hole mounting required for PCB compatibility
• Pitch: 0.100" (2.54mm) standard spacing required for footprint alignment
• RoHS Compliance: ROHS3 status required for regulatory alignment

Flexible Parameters (Application-Dependent):

• Actuator Type: Rocker versus slide actuator selection depends on panel design and user interface requirements
• Current Rating: Substitute must equal or exceed 60mA minimum
• Voltage Rating: Substitute must support application operating voltage
• Operating Temperature: Substitute range must encompass application environment
• Mechanical/Electrical Life: Substitute cycle ratings must meet application duty cycle

The substitute part TE Connectivity ALCOSWITCH 1825057-6 maintains SPST circuit configuration, 7-position count, through-hole mounting, and 0.100" pitch specification. Differences in actuator type (slide versus rocker), current rating (100mA versus 60mA), voltage rating (24VDC versus 5VDC), and operating temperature range represent design trade-offs that require application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in 5VDC Applications:

The 1825057-6 substitute is not recommended as a direct replacement when the application circuit operates at 5VDC. The substitute is rated for 24VDC operation. Using a 24VDC-rated component in a 5VDC circuit may result in contact resistance variations and unreliable switching performance outside the component's specified operating voltage range.

For Applications Requiring Rocker Actuator Interface:

The 1825057-6 features a slide actuator, whereas the 5435640-1 uses a rocker actuator. Panel cutout geometry, user interface design, and mechanical mounting configurations are specific to actuator type. Substitution requires panel redesign and mechanical re-qualification.

For High-Cycle Duty Applications:

The 5435640-1 is rated for 2,000 mechanical and electrical cycles, while the 1825057-6 is rated for 1,000 cycles. Applications requiring cycle counts exceeding 1,000 should retain the original 5435640-1 specification or identify alternative parts with higher cycle ratings.

For Extended Temperature Range Requirements:

The 5435640-1 operates across -55°C to 105°C, while the 1825057-6 operates across -30°C to 85°C. Applications requiring operation below -30°C or above 85°C must use the original 5435640-1 or identify alternative parts with extended temperature specifications.

For Active Production and Supply Continuity:

The 1825057-6 holds Active product status with 7,269 units in stock, compared to the 5435640-1 Last Time Buy status with 6,966 units in stock. For new designs or long-term production requirements, the 1825057-6 provides supply continuity, provided application voltage, actuator type, and cycle requirements are compatible.

Regulatory and Compliance Alignment:

Both parts are ROHS3 compliant with MSL 1 (Unlimited) rating and EAR99 ECCN classification. Both are suitable for applications with equivalent regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1825057-6 substitute for the 5435640-1 in a 5VDC circuit?

A: No. The 1825057-6 is rated for 24VDC operation. Substitution in a 5VDC circuit places the component outside its specified voltage operating range and may result in unreliable switching performance. The application circuit voltage must match the component voltage rating.

Q: What is the primary difference between rocker and slide actuators?

A: Rocker actuators (5435640-1) feature a pivoting lever mechanism, while slide actuators (1825057-6) use a linear push-pull interface. These actuator types require different panel cutout geometries and mounting configurations. Substitution requires mechanical redesign of the panel interface.

Q: Is the 1825057-6 suitable for applications requiring 2,000 cycle operation?

A: No. The 1825057-6 is rated for 1,000 mechanical and electrical cycles, while the 5435640-1 is rated for 2,000 cycles. Applications with cycle requirements exceeding 1,000 must use the original 5435640-1 or identify alternative parts with higher cycle ratings.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5435640-1 and 1825057-6 are ROHS3 compliant and suitable for applications with equivalent regulatory requirements.

Q: What is the operating temperature difference between these parts?

A: The 5435640-1 operates from -55°C to 105°C, while the 1825057-6 operates from -30°C to 85°C. The 5435640-1 provides a wider temperature range. Applications requiring operation below -30°C or above 85°C must use the original 5435640-1.

Q: Do both parts use the same PCB pitch and mounting method?

A: Yes. Both parts use 0.100" (2.54mm) pitch spacing and through-hole mounting. PCB footprint compatibility is maintained between these parts.

Q: What is the current rating difference, and does it affect substitution?

A: The 5435640-1 is rated for 60mA, while the 1825057-6 is rated for 100mA. The substitute's higher current rating is compatible with 60mA applications. Current rating compatibility is satisfied by the substitute.

Q: Why is the 5435640-1 classified as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. The 1825057-6, classified as Active, remains in production. For long-term supply requirements, the Active part provides production continuity, provided application parameters are compatible.

Q: Can the 1825057-6 be used in applications with extended temperature requirements below -30°C?

A: No. The 1825057-6 minimum operating temperature is -30°C. Applications requiring operation below -30°C must use the original 5435640-1 or identify alternative parts with extended low-temperature specifications.

Q: Are the contact materials and finishes identical?

A: Yes. Both parts use copper alloy contacts with gold finish, ensuring consistent electrical performance and contact reliability.
