Key Parameters

Substitute Part Grouping Explanation

Substitution of the 59075-1-S-02-F is determined by strict equivalence across the following parameters:

• Output Configuration: SPST-NO switching behavior must be maintained
• Actuator Type: Magnet-actuated operation required
• Termination: Wire leads connection style
• Package Form: Cylinder threaded housing
• Temperature Range: -40°C to 105°C operational limits
• Compliance: ROHS3 compliance and MSL Level 1 rating

The 59075-1-S-02-A meets all these criteria while maintaining active product status within the same Littelfuse 59075 series.

Parameter Comparison

Engineering Selection Recommendations

The 59075-1-S-02-A is the direct functional equivalent for the obsolete 59075-1-S-02-F. Both components share identical electrical and mechanical specifications within the Littelfuse 59075 series. The primary distinction is product lifecycle status: the 59075-1-S-02-A maintains active manufacturing and distribution status, ensuring long-term availability and supply chain continuity.

For applications currently utilizing the 59075-1-S-02-F, direct substitution with the 59075-1-S-02-A is supported by matching ROHS3 compliance and MSL Level 1 ratings. No design modifications or circuit alterations are required.

Frequently Asked Questions (FAQ)

Q: Can the 59075-1-S-02-A directly replace the 59075-1-S-02-F without design changes?

A: Yes. Both components are identical in electrical function (SPST-NO reed switch), mechanical package (cylinder threaded), termination style (wire leads), and operating temperature range (-40°C to 105°C). Direct substitution is supported.

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

A: The 59075-1-S-02-F is classified as obsolete, while the 59075-1-S-02-A is an active product. The suffix letter (F vs. A) indicates product lifecycle status within Littelfuse's 59075 series. Functional specifications remain equivalent.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is identical.

Q: What should I do if I have existing inventory of the 59075-1-S-02-F?

A: Existing inventory can continue to be used in current applications. For new designs or replenishment, transition to the 59075-1-S-02-A to ensure ongoing supply availability and manufacturer support.

Q: Are the wire lead specifications identical between these parts?

A: Yes. Both components use wire leads termination in the same cylinder threaded package configuration. Physical and electrical connection characteristics are equivalent.
