Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for DIP switches is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish whether a part can serve as a direct substitute for the 1-5435802-7:

Mandatory Matching Parameters:

• Circuit configuration (SPST)
• Number of positions (6)
• Current rating (25mA)
• Voltage rating (24VDC)
• Actuator type (Piano)
• Mounting type (Through Hole, Right Angle)
• Termination style (PC Pin)
• Pitch (0.100" / 2.54mm)
• Contact material and finish (Copper Alloy, Gold)
• Washable capability (Yes)
• RoHS compliance (ROHS3)
• MSL rating (1)

The substitute part 1-1571999-6 meets all mandatory electrical and mechanical parameters required for direct substitution. Variations in operating temperature range, mechanical/electrical life cycles, body material composition, and physical dimensions within tolerance are acceptable provided core functional parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 1-1571999-6 is a direct electrical and mechanical substitute for the 1-5435802-7. Both parts are manufactured by TE Connectivity, carry ROHS3 compliance certification, and maintain identical electrical ratings and switching characteristics.

Selection Basis:

The 1-1571999-6 is recommended for new designs and production transitions due to its Active product status, ensuring long-term availability and supply chain stability. The 1-5435802-7, designated as Last Time Buy, has limited remaining inventory and will not be replenished.

Operational Considerations:

The substitute part operates within a narrower temperature range (-30°C to 85°C versus -55°C to 105°C). Applications requiring operation below -30°C or above 85°C must retain the original 1-5435802-7 specification or identify alternative solutions.

The substitute part carries lower mechanical and electrical life ratings (1,000 cycles versus 7,000 cycles). Applications with duty cycles exceeding 1,000 switching operations must evaluate whether the reduced cycle rating presents a constraint.

Both parts maintain equivalent electrical performance at the specified 25mA, 24VDC rating and are suitable for direct PCB substitution with identical footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1-1571999-6 be used as a direct replacement for the 1-5435802-7 on existing PCBs?

A: Yes. Both parts share identical mounting type (through-hole, right-angle), pitch (0.100"), and termination style (PC pin). Physical dimensions are within tolerance. No PCB redesign is required.

Q: What is the primary reason for substitution?

A: The 1-5435802-7 carries Last Time Buy status and will not be restocked. The 1-1571999-6 is an Active product with continuous manufacturing and supply availability.

Q: Are there electrical performance differences between these parts?

A: No. Both parts are rated identically at 25mA, 24VDC with SPST 6-position configuration. Switching performance and contact characteristics are equivalent.

Q: Does the substitute part meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical.

Q: What are the differences in operating temperature range?

A: The 1-5435802-7 operates from -55°C to 105°C. The 1-1571999-6 operates from -30°C to 85°C. Applications requiring extreme temperature operation must confirm the substitute range is acceptable.

Q: How do the mechanical life ratings differ?

A: The 1-5435802-7 is rated for 7,000 mechanical cycles. The 1-1571999-6 is rated for 1,000 mechanical cycles. High-cycle applications must evaluate whether the lower rating is suitable.

Q: Is the body material difference significant?

A: The 1-5435802-7 uses glass-filled polyester (PET). The 1-1571999-6 uses polyphenylene sulfide (PPS). Both materials provide adequate mechanical and environmental protection for standard industrial applications. PPS offers superior chemical resistance in certain environments.

Q: Can both parts be used interchangeably in new designs?

A: The 1-1571999-6 is recommended for new designs due to Active product status and guaranteed long-term availability. The 1-5435802-7 should be used only when specific application requirements (extended temperature range or higher cycle rating) mandate its selection.
