Engineering Selection Recommendations

The SCHURTER 3-145-506 is the manufacturer-recommended substitute for the obsolete 3-125-836. Selection of the active part number is appropriate for new designs and ongoing production requirements. For legacy system maintenance where original part number retention is mandated, the 3-125-836 remains available from existing inventory. The substitute part maintains full functional equivalence within the MSM-19 series, eliminating the need for circuit redesign or mechanical re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the 3-145-506 directly replace the 3-125-836 in existing applications? A: Yes. Both components are members of the MSM-19 pushbutton switch series from SCHURTER Inc. and share identical functional specifications, making them mechanically and electrically interchangeable.

Q: Why is the original part number obsolete? A: The 3-125-836 has been superseded by the 3-145-506 within SCHURTER's product line. The manufacturer recommends transitioning to the active part number for new procurements and production builds.

Q: Are there packaging differences between these part numbers? A: Both components utilize standard packaging configurations consistent with the MSM-19 series. No packaging modifications are required for substitution.

Q: Should I use the legacy part or the substitute for new designs? A: New designs should specify the 3-145-506, as it is the active, manufacturer-supported component. The 3-125-836 should be reserved for legacy system maintenance only.
