Key Parameters

Substitute Part Grouping Explanation

The substitute part 3-145-599 qualifies as a direct equivalent based on the following matching parameters:

• Identical manufacturer (SCHURTER Inc.)
• Same product series (MSM30)
• Identical contact configuration (SPDT)
• Matching current rating (100mA)
• Same functional description (Pushbutton Switch)
• Active product status enabling continued supply and support

The substitution is valid because all critical electrical and mechanical parameters remain unchanged between the original and substitute part.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-599 is the manufacturer-recommended substitute for the obsolete 3-100-938. Selection of the active part is appropriate for:

• New production designs requiring current component availability
• System redesigns where obsolete part sourcing presents supply chain risk
• Applications requiring manufacturer support and technical documentation access

The original part may be retained for legacy system maintenance where existing inventory is available and functional requirements remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the 3-145-599 be used as a direct replacement for the 3-100-938?

A: Yes. Both parts share identical electrical specifications (SPDT configuration, 100mA rating) and mechanical form factor within the MSM30 series, confirming direct substitution compatibility.

Q: What is the primary reason for substitution?

A: The 3-100-938 is obsolete. The 3-145-599 is an active product from the same manufacturer and series, ensuring continued availability and support.

Q: Are there packaging differences between these parts?

A: Packaging information is not provided in the technical specifications for either part. Consult SCHURTER datasheets or contact the manufacturer for packaging details.

Q: Should I transition existing designs to the substitute part?

A: Transition is recommended for new production to ensure long-term supply chain stability. Existing systems using the original part may continue operation if inventory is available.

Q: Are there any electrical parameter differences?

A: No. Both parts maintain identical current rating (100mA), contact configuration (SPDT), and functional classification as pushbutton switches.
