Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2012SS2W08 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Current rating must support minimum 6A AC / 4A DC
• Voltage rating must support minimum 125V AC / 30V DC
• Operating temperature range must encompass -30°C to 85°C

Mechanical Compatibility Requirements:

• Panel cutout dimensions must be Circular - 6.50mm Dia
• Actuator type must be Standard Round
• Actuator length must be 10.50mm
• Base product number must be M2012SS (same family)

Acceptable Variations:

• Mounting type may differ (Through Hole, Panel Mount)
• Termination style may differ (Wire Wrap, Solder Lug, PC Pin)
• Product status may differ (Active or Obsolete)
• Packaging configuration may differ

The M2012SS2W08 shares the M2012SS base product number with substitute candidates M2012SS2W01 and M2012SS2W03, confirming family compatibility and interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

M2012SS2W01 (Panel Mount, Solder Lug Termination)

This substitute is classified as Active product status, providing long-term availability and supply chain stability. It maintains full electrical equivalence with identical current and voltage ratings. The primary design consideration is the transition from Through Hole to Panel Mount configuration and from Wire Wrap to Solder Lug termination. This substitute is suitable for applications where panel mounting is acceptable and solder lug connections are compatible with the circuit board design.

M2012SS2W03 (Through Hole, PC Pin Termination)

This substitute maintains the Through Hole mounting type of the original M2012SS2W08, simplifying mechanical integration. The termination style differs, using PC Pin instead of Wire Wrap. Product status is Obsolete, matching the original part classification. This substitute is suitable for applications requiring through-hole mounting where PC Pin termination is compatible with the circuit board design.

Frequently Asked Questions (FAQ)

Q: Can M2012SS2W01 replace M2012SS2W08 in existing designs?

A: M2012SS2W01 is electrically equivalent and shares identical electrical ratings. Compatibility depends on whether the design can accommodate Panel Mount configuration and Solder Lug termination instead of Through Hole and Wire Wrap. Panel cutout dimensions remain identical at 6.50mm circular.

Q: What is the primary difference between M2012SS2W03 and M2012SS2W08?

A: Both parts maintain Through Hole mounting and identical electrical specifications. The difference is termination style: M2012SS2W08 uses Wire Wrap while M2012SS2W03 uses PC Pin. Selection depends on circuit board design requirements for terminal connection method.

Q: Are all three parts electrically interchangeable?

A: Yes. M2012SS2W08, M2012SS2W01, and M2012SS2W03 are electrically interchangeable, all supporting 6A AC at 125V and 4A DC at 30V with SPDT On-On configuration. Mechanical compatibility requires matching mounting type and termination style to the circuit board design.

Q: Why is M2012SS2W08 marked as Obsolete?

A: Product status reflects manufacturer discontinuation. M2012SS2W01 is available as an Active substitute, providing current production availability. M2012SS2W03 remains Obsolete but is available from existing inventory.

Q: What packaging options are available?

A: M2012SS2W08 is supplied in standard packaging. M2012SS2W03 is available in Bulk packaging. Packaging selection should align with production volume and inventory management requirements.

Q: Are there compliance differences between the substitutes?

A: M2012SS2W08 and M2012SS2W03 are ROHS3 Compliant. M2012SS2W01 is RoHS Compliant. All three parts are EAR99 classified and REACH Unaffected. Compliance selection depends on end-use application requirements.
