Littelfuse 59010-1-T-01-F Magnetic Reed Switch Equivalent & Substitute Parts

Part Overview

The Littelfuse 59010-1-T-01-F is a magnetic reed switch sensor with SPST-NO (Single Pole Single Throw - Normally Open) output configuration, designed for magnetic actuation applications. This component features wire leads with connector probe termination and operates across a temperature range of -40°C to 85°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure ongoing component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 59010-1-T-01-F is determined by strict alignment of the following critical parameters:

• Output Type: SPST-NO configuration must be maintained
• Actuator Material: Magnet-based actuation required
• Must Operate Distance: 4.50mm actuation threshold
• Operating Temperature Range: -40°C to 85°C operational limits
• Series Compatibility: 59010 series designation
• RoHS Compliance: ROHS3 Compliant status
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The identified substitute parts maintain electrical and mechanical compatibility through identical parameter specifications across all critical selection criteria. Termination style variations (Wire Leads versus Wire Leads with Connector) represent acceptable mechanical alternatives within the same functional category, provided the electrical interface requirements of the application are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (59010-1-T-02-A and 59010-1-T-02-F) are classified as active products, providing assured long-term availability compared to the obsolete 59010-1-T-01-F. Both alternatives maintain full ROHS3 compliance and identical electrical specifications.

59010-1-T-02-F is the primary recommended substitute, offering direct mechanical compatibility through identical Wire Leads with Connector termination style and bulk packaging availability (1948 pcs in stock).

59010-1-T-02-A serves as an alternative substitute with Wire Leads termination (without connector), suitable for applications where connector probe integration is not required. This variant provides 995 pcs inventory availability.

Selection between the two active alternatives should be based on termination interface requirements specific to the application circuit design.

Frequently Asked Questions (FAQ)

Q: Can 59010-1-T-02-A and 59010-1-T-02-F be used interchangeably with 59010-1-T-01-F?

A: Both parts maintain identical electrical and mechanical specifications (SPST-NO output, 4.50mm actuation distance, -40°C to 85°C operating range). The primary difference is termination style: 59010-1-T-02-F includes connector probe (matching the original), while 59010-1-T-02-A provides wire leads only. Selection depends on your circuit interface requirements.

Q: Why is the original part obsolete?

A: The 59010-1-T-01-F is classified as obsolete by the manufacturer. The active alternatives (59010-1-T-02-A and 59010-1-T-02-F) provide equivalent functionality with assured ongoing availability.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All three parts maintain identical ROHS3 compliance, MSL 1 (Unlimited) rating, and equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8536.50.9065).

Q: What is the difference between termination styles?

A: 59010-1-T-01-F and 59010-1-T-02-F feature Wire Leads with Connector probe termination. 59010-1-T-02-A provides Wire Leads termination without connector. Both are mechanically compatible with probe-based mounting; connector presence affects circuit interface methodology only.

Q: Which substitute should I select for new designs?

A: For direct replacement with identical termination, select 59010-1-T-02-F. For applications requiring wire-only termination, select 59010-1-T-02-A. Both are active products with confirmed inventory availability.
