Frequently Asked Questions (FAQ)

Q: Can the 1825190-7 be used as a direct replacement for the 435704-8 in existing designs?

A: Yes. The 1825190-7 is electrically and mechanically identical to the 435704-8 across all specified parameters. No design modifications are required for substitution.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and regulatory compliance. The 435704-8 is obsolete and RoHS non-compliant, while the 1825190-7 is an active product with ROHS3 compliance. All functional specifications remain identical.

Q: Are there any packaging differences that affect assembly?

A: The 435704-8 packaging is not specified in the available data. The 1825190-7 is supplied in tube packaging, which is standard for through-hole DIP switches and compatible with conventional pick-and-place assembly equipment.

Q: Does the RoHS3 compliance of the 1825190-7 affect performance?

A: No. RoHS3 compliance relates to material composition and environmental regulations, not electrical or mechanical performance. The 1825190-7 maintains identical operating characteristics to the 435704-8.

Q: What is the pitch specification, and why is it important?

A: Both components have a pitch of 0.100" (2.54mm), Full. This specification defines the spacing between switch positions and is critical for PCB layout compatibility. Identical pitch ensures direct board-level substitution.
