Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 3-109-580 are identified based on strict equivalence of the following electrical and mechanical parameters:

• Contact configuration: SPDT (Single Pole Double Throw)
• Contact type: Momentary contact (MO) with normally open (NX) characteristics
• Current rating: 100mA
• Series compatibility: MSM22 series
• Manufacturer: SCHURTER Inc.
• RoHS compliance: ROHS3 Compliant

The substitute part must maintain identical electrical specifications and physical form factor to ensure direct replacement capability without circuit redesign or mechanical modification.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-638 serves as the direct substitute for the obsolete 3-109-580. Both components are manufactured by SCHURTER Inc., belong to the MSM22 series, and maintain identical electrical specifications including SPDT contact configuration, 100mA current rating, and momentary contact operation. The primary distinction is product status: the 3-145-638 is currently active in production, ensuring availability for procurement and long-term supply chain stability. Both parts maintain ROHS3 compliance, satisfying environmental and regulatory requirements. Selection of the 3-145-638 eliminates obsolescence risk while preserving full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-638 be used as a direct replacement for the 3-109-580?

A: Yes. Both components share identical electrical specifications: SPDT contact configuration, momentary contact operation with normally open characteristics, and 100mA current rating. The 3-145-638 is the active production equivalent of the obsolete 3-109-580.

Q: What is the primary reason to substitute the 3-109-580?

A: The 3-109-580 is classified as obsolete. The 3-145-638 provides equivalent functionality with active product status, ensuring continued availability and supply chain reliability.

Q: Are there any mechanical or packaging differences between these parts?

A: Both components are from the MSM22 series and maintain compatible form factors. No mechanical modification or circuit redesign is required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 3-109-580 and 3-145-638 are ROHS3 compliant, satisfying current environmental and regulatory requirements.

Q: What electrical parameters must remain constant when substituting this component?

A: The contact configuration (SPDT), contact type (momentary, normally open), and current rating (100mA) must remain unchanged. These parameters define the functional equivalence of substitute parts.
