Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5435640-7 is based on the following electrical and mechanical parameters that must be evaluated for circuit compatibility:

Electrical Parameters:

• Circuit configuration (SPST maintained)
• Number of positions (10 positions maintained)
• Current rating capability (minimum 60mA required)
• Voltage rating (minimum 5VDC required)
• Contact material and finish (Copper Alloy with Gold finish)

Mechanical Parameters:

• Mounting type (Through Hole maintained)
• Pitch spacing (0.100" / 2.54mm maintained)
• Termination style (PC Pin maintained)
• Operating temperature range (must encompass application requirements)
• RoHS3 compliance (regulatory requirement maintained)

The substitute part ADE10A04 maintains the core SPST 10-position configuration with through-hole mounting and standard pitch. Differences in actuator type (slide versus rocker), current rating (100mA versus 60mA), voltage rating (24VDC versus 5VDC), and mechanical life cycles represent design trade-offs that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The 5435640-7 is designated Last Time Buy, indicating end-of-life status with no future production. The ADE10A04 is classified as Active, ensuring continued availability and supply chain support for new designs and ongoing production requirements.

Compliance and Certification

Both parts maintain ROHS3 compliance and share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, ensuring regulatory equivalence for export and procurement purposes.

Electrical Compatibility Assessment

The ADE10A04 provides higher current rating (100mA versus 60mA) and higher voltage rating (24VDC versus 5VDC). Applications operating at 5VDC with 60mA maximum current draw are electrically compatible with the ADE10A04, as the substitute part exceeds minimum electrical requirements. However, applications requiring operation specifically at 5VDC must verify that the 24VDC rating does not introduce design constraints or safety concerns in the target circuit.

Mechanical and Thermal Considerations

The ADE10A04 operates within a narrower temperature range (-30°C ~ 85°C) compared to the 5435640-7 (-55°C ~ 105°C). Applications requiring operation below -30°C or above 85°C are not compatible with the substitute part. The ADE10A04 exhibits reduced mechanical and electrical life (1,000 cycles versus 2,000 cycles), which must be evaluated against application duty cycle requirements.

Physical Integration

The ADE10A04 is 0.112" (2.84mm) lower in height above board compared to the 5435640-7. PCB layout and enclosure clearance must be verified to accommodate this dimensional difference. The actuator type differs (slide versus rocker), which may affect user interface ergonomics and panel mounting considerations.

Frequently Asked Questions (FAQ)

Q: Can the ADE10A04 directly replace the 5435640-7 in existing designs?

A: Direct replacement requires verification of three critical factors: (1) operating temperature range compatibility, (2) mechanical life cycle requirements, and (3) physical clearance for the reduced height profile and different actuator type. Electrical parameters are compatible for applications operating at 5VDC with 60mA or less.

Q: What is the primary reason for seeking a substitute part?

A: The 5435640-7 is Last Time Buy status, indicating discontinued production. The ADE10A04 is an Active product from the same manufacturer with equivalent SPST 10-position configuration, ensuring long-term supply availability.

Q: Are there differences in washability between these parts?

A: Yes. The 5435640-7 is not washable, while the ADE10A04 is washable. Applications requiring post-assembly cleaning must account for this difference in material composition and design.

Q: How do the mechanical life ratings compare?

A: The 5435640-7 provides 2,000 mechanical and electrical cycles, while the ADE10A04 provides 1,000 cycles. Applications with high actuation frequency must evaluate whether the reduced cycle rating is acceptable for the intended duty cycle.

Q: What is the impact of the different actuator types?

A: The 5435640-7 uses a rocker actuator, while the ADE10A04 uses a slide (standard) actuator. This affects user interface feel, panel mounting requirements, and physical space allocation. PCB layout and enclosure design must accommodate the different actuator geometry.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 5435640-7 and ADE10A04 are ROHS3 compliant, ensuring regulatory equivalence for environmental and hazardous substance restrictions.

Q: What is the significance of the different body materials?

A: The 5435640-7 uses Polyester (PET) with glass fill, while the ADE10A04 uses Polyphenylene Sulfide (PPS). The PPS material in the ADE10A04 provides enhanced chemical resistance and contributes to its washable design. Operating temperature and chemical exposure environments must be considered when evaluating material suitability.

Q: Can the ADE10A04 be used in applications requiring -55°C operation?

A: No. The ADE10A04 operating temperature range begins at -30°C. Applications requiring operation at -55°C must retain the 5435640-7 or identify alternative parts with extended low-temperature ratings.
