Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-1825059-4 is functionally equivalent to the ADF04SA across all critical electrical and mechanical parameters. The primary distinctions are:

Product Status: The ADF04SA is classified as obsolete, while 1-1825059-4 maintains active product status with ongoing manufacturer support and availability.

Compliance: The 1-1825059-4 achieves ROHS3 compliance, whereas the ADF04SA is RoHS non-compliant. For applications subject to RoHS regulations, the 1-1825059-4 is the appropriate selection.

Packaging: The ADF04SA is supplied in standard packaging, while 1-1825059-4 is available in Tape & Reel (TR) format, suitable for automated assembly processes.

Electrical and Mechanical Compatibility: Both components share identical circuit configuration, position count, actuator characteristics, mounting type, and operating parameters, ensuring direct functional substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 1-1825059-4 directly replace the ADF04SA in existing designs?

A: Yes. Both components are SPST 4-position DIP switches with identical actuator types, mounting methods, and electrical ratings. The 1-1825059-4 maintains the same pitch spacing, termination style, and operating temperature range, enabling direct substitution without circuit modification.

Q: What is the significance of the product status difference?

A: The ADF04SA is obsolete, indicating discontinued manufacturing and limited availability. The 1-1825059-4 is active, ensuring continued supply, technical support, and compliance with current manufacturing standards.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance is a regulatory requirement for specific markets and applications. If your application or end market requires RoHS compliance, the 1-1825059-4 is mandatory. If RoHS compliance is not required, both components are functionally equivalent.

Q: Are there packaging considerations for automated assembly?

A: The 1-1825059-4 is supplied in Tape & Reel (TR) packaging, optimized for automated pick-and-place assembly. The ADF04SA uses standard packaging. If automated assembly is required, the 1-1825059-4 is the appropriate selection.

Q: Do both components have identical electrical ratings?

A: The provided specifications confirm both components are rated for 25mA at 24VDC with SPST configuration and 4-position operation. Electrical performance is equivalent.

Q: What is the moisture sensitivity level for both components?

A: Both the ADF04SA and 1-1825059-4 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
