MFS101D-11-Z Equivalent & Substitute Parts

Part Overview

The MFS101D-11-Z is a slide switch SPDT (Single Pole Double Throw) component manufactured by Nidec Components Corporation, designed for through-hole, right-angle mounting applications. This part is rated for 300mA DC at 12V with non-shorting contact timing and on-on switch function. The product status is obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MFS101D-11-Z is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT (maintained)
• Contact timing: Non-shorting (BBM) (maintained)
• Switch function: On-on (maintained)
• Voltage rating: 12V DC (maintained)
• Mounting type: Through hole, right angle (maintained)
• Termination style: PC pin (maintained)

Secondary Compatibility Criteria:

• Current rating: Must equal or exceed 300mA
• Operating temperature range: Must encompass or exceed -10°C ~ 70°C
• RoHS compliance: ROHS3 compliant (maintained)

The substitute part CL-SA-12C4-02 meets all primary criteria and exceeds secondary criteria with a 500mA current rating and extended operating temperature range of -40°C ~ 85°C.

Parameter Comparison

Engineering Selection Recommendations

The CL-SA-12C4-02 is a direct functional substitute for the obsolete MFS101D-11-Z. Both components are manufactured by Nidec Components Corporation and maintain identical circuit configuration, contact timing, switch function, voltage rating, and mounting specifications.

The CL-SA-12C4-02 provides enhanced electrical performance with a 500mA current rating compared to the 300mA rating of the MFS101D-11-Z, allowing operation in applications with higher current demands within the same 12V DC voltage envelope. The extended operating temperature range of -40°C ~ 85°C provides broader environmental compatibility compared to the -10°C ~ 70°C range of the original part.

Both components are ROHS3 compliant and maintain identical termination and mounting characteristics, ensuring direct PCB layout compatibility. The CL-SA-12C4-02 is currently in active production status, providing long-term supply chain availability and procurement stability.

Frequently Asked Questions (FAQ)

Q: Can the CL-SA-12C4-02 be used as a direct replacement for the MFS101D-11-Z?

A: Yes. Both components share identical circuit configuration (SPDT), contact timing (non-shorting BBM), switch function (on-on), voltage rating (12V DC), mounting type (through hole, right angle), and termination style (PC pin). The CL-SA-12C4-02 exceeds the current rating requirement and operates across a wider temperature range.

Q: What are the key differences between these two parts?

A: The primary differences are current rating (500mA vs. 300mA), operating temperature range (-40°C ~ 85°C vs. -10°C ~ 70°C), electrical life (2,000 cycles vs. 5,000 cycles), and product status (active vs. obsolete). The CL-SA-12C4-02 provides higher current capacity and broader environmental operating conditions.

Q: Are there any packaging differences between the MFS101D-11-Z and CL-SA-12C4-02?

A: Both components use through-hole, right-angle mounting with PC pin termination. The CL-SA-12C4-02 is supplied in bulk packaging. Physical dimensions and PCB footprints are compatible for direct substitution.

Q: Does the CL-SA-12C4-02 maintain RoHS compliance?

A: Yes. The CL-SA-12C4-02 is ROHS3 compliant, matching the compliance status of the MFS101D-11-Z.

Q: Why is the electrical life rating lower for the CL-SA-12C4-02?

A: The electrical life specification reflects the rated cycle performance under specified operating conditions. The CL-SA-12C4-02 is rated for 2,000 cycles compared to 5,000 cycles for the MFS101D-11-Z. Application requirements should be evaluated against these specifications.
