Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5435802-9 is based on electrical and mechanical parameter equivalence within the DIP switch product category. The following parameters must remain constant or compatible for a part to function as a direct substitute:

Critical Matching Parameters:

• Circuit type: SPST
• Number of positions: 8
• Current rating: 25mA minimum
• Voltage rating: 24VDC
• Actuator type: Piano
• Mounting configuration: Through hole, right angle
• Pitch spacing: 0.100" (2.54mm)
• Contact material and finish: Copper alloy with gold plating
• Termination style: PC pin
• RoHS3 compliance status

The TE Connectivity ALCOSWITCH 2-1571999-6 meets all critical electrical and mechanical parameters required for substitution. Both components share identical circuit configuration, position count, current and voltage ratings, actuator characteristics, and mounting specifications. Physical dimensions remain within acceptable tolerance ranges for PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 2-1571999-6 is a qualified substitute for the 5435802-9 based on electrical and mechanical equivalence. Both components are manufactured by TE Connectivity ALCOSWITCH Switches and maintain ROHS3 compliance with identical export classification (EAR99) and tariff codes.

Product Status Consideration: The 5435802-9 is designated Last Time Buy, while the 2-1571999-6 maintains Active product status. This status difference indicates that the 2-1571999-6 represents the current production alternative within the TE Connectivity ALCOSWITCH portfolio.

Compliance and Certification: Both parts satisfy ROHS3 requirements and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental compliance for manufacturing and storage.

Physical and Electrical Compatibility: Dimensional variations between the two parts are minimal (height difference of 0.003 inches, length difference of 0.002 inches), presenting no functional impact on PCB layout or electrical performance. Both components feature identical pitch spacing (0.100 inches), contact materials, and termination styles, ensuring direct PCB footprint compatibility.

Operational Differences: The 2-1571999-6 operates within a narrower temperature range (-30°C to 85°C versus -55°C to 105°C) and exhibits reduced mechanical and electrical life ratings (1,000 cycles versus 7,000 cycles). These differences require evaluation against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2-1571999-6 be used as a direct replacement for the 5435802-9 on existing PCBs?

A: Yes. Both components share identical pitch spacing (0.100 inches), mounting configuration (through hole, right angle), and termination style (PC pin). Physical dimensions are within acceptable tolerance ranges for PCB compatibility. No layout modifications are required.

Q: What are the key electrical differences between these two DIP switches?

A: Both components are electrically equivalent for the specified application parameters: SPST circuit, 8 positions, 25mA current rating, and 24VDC voltage rating. Contact material, finish, and washability are identical.

Q: Why does the 2-1571999-6 have a lower mechanical and electrical life rating?

A: The 2-1571999-6 is rated for 1,000 cycles compared to 7,000 cycles for the 5435802-9. This difference reflects design variations between the 7000 series and ADP series within the TE Connectivity ALCOSWITCH product line. Application requirements must be evaluated to determine if the reduced cycle rating is acceptable.

Q: Are there temperature range limitations with the 2-1571999-6?

A: The 2-1571999-6 operates from -30°C to 85°C, compared to -55°C to 105°C for the 5435802-9. Applications requiring operation outside the -30°C to 85°C range require the original 5435802-9 or alternative components with extended temperature specifications.

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

A: The 5435802-9 uses Polyester (PET) with glass filling, while the 2-1571999-6 uses Polyphenylene Sulfide (PPS). Both materials are suitable for industrial switching applications and provide equivalent environmental protection. Material selection reflects manufacturing process differences between the two series.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5435802-9 and 2-1571999-6 are ROHS3 compliant and carry identical MSL Level 1 (Unlimited) ratings, ensuring equivalent environmental and manufacturing compliance.

Q: What does the Last Time Buy status mean for the 5435802-9?

A: Last Time Buy indicates that TE Connectivity is discontinuing production of the 5435802-9. The 2-1571999-6 represents the active production alternative. New designs should transition to the 2-1571999-6 to ensure long-term supply availability.
