MDS003 Equivalent & Substitute Parts

Part Overview

The C&K MDS003 is a snap-action switch with SPDT (Single Pole Double Throw) configuration, rated for 300mA DC at 30V. This component features a straight lever actuator and through-hole right-angle mounting with PC pin termination. The MDS003 is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The MDS6500AL02RS qualifies as a direct substitute for the MDS003 based on matching electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

• Circuit configuration (SPDT) and switch function (On-Momentary) are identical
• Current and voltage ratings (300mA DC, 30V) are equivalent
• Actuator type (straight lever) and mounting configuration (through-hole, right-angle) are identical
• Termination style (PC pin) matches the original design
• Operating and release forces (50gf and 3.000gf respectively) are identical
• Electrical and mechanical life ratings (30,000 cycles each) are equivalent

The MDS6500AL02RS belongs to the same MDS series family and maintains full compatibility with the original part's electrical and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The MDS6500AL02RS is the qualified substitute for the obsolete MDS003. Both parts maintain identical electrical ratings, mechanical interfaces, and operational characteristics. The substitute part offers an extended operating temperature range (-25°C to 70°C versus -10°C to 60°C), providing broader environmental compatibility. The MDS6500AL02RS carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Both parts are REACH Unaffected and classified under ECCN EAR99. The substitute part is available in bulk packaging with higher inventory levels, supporting production requirements.

Frequently Asked Questions (FAQ)

Q: Can the MDS6500AL02RS replace the MDS003 in existing designs?

A: Yes. The MDS6500AL02RS maintains identical electrical ratings (300mA DC, 30V), circuit configuration (SPDT), switch function (On-Momentary), actuator type (straight lever), mounting configuration (through-hole, right-angle), and termination style (PC pin). Operating and release forces are equivalent at 50gf and 3.000gf respectively.

Q: What are the differences between these parts?

A: The primary differences are product status and operating temperature range. The MDS003 is obsolete with an operating range of -10°C to 60°C, while the MDS6500AL02RS is active with an extended range of -25°C to 70°C. The substitute part also carries ROHS3 compliance versus RoHS compliance on the original.

Q: Are there packaging considerations for the substitute part?

A: The MDS6500AL02RS is supplied in bulk packaging, whereas the MDS003 packaging specification was not provided. Verify bulk packaging compatibility with your assembly and procurement processes.

Q: Do both parts have the same mechanical life expectancy?

A: Yes. Both the MDS003 and MDS6500AL02RS are rated for 30,000 electrical cycles and 30,000 mechanical cycles.

Q: Is the MDS6500AL02RS suitable for applications requiring the full -10°C to 60°C range of the original?

A: Yes. The MDS6500AL02RS operating range of -25°C to 70°C encompasses the original specification, providing full compatibility and additional margin.
