Substitute Part Grouping Explanation

Substitution eligibility for the 7101SD9WME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole)
• Actuator type and length (Standard Round, 12.45mm)
• Termination style (Wire Wrap)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 Cycles)
• Base product number (7101SD)

The C&K 7101SD9WSE meets all substitution criteria. Both parts share identical electrical specifications, mechanical dimensions, and functional characteristics within the 7000 series family.

Parameter Comparison

Engineering Selection Recommendations

Selection between these parts should be based on regulatory requirements specific to the end application and target market.

Frequently Asked Questions (FAQ)

Q: Can the 7101SD9WSE directly replace the 7101SD9WME in existing designs?

A: Yes. Both components are electrically and mechanically equivalent. They share identical circuit configuration (SPDT), current rating (5A AC/DC), voltage ratings (120V AC, 28V DC), mounting type (Through Hole), actuator specifications, and termination style (Wire Wrap). No circuit modifications are required.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant?

A: ROHS3 refers to the third iteration of the Restriction of Hazardous Substances directive. Both designations indicate compliance with RoHS requirements; the difference reflects the version of the directive under which each part was certified.

Q: Are there any packaging differences between these parts?

A: Packaging information is not provided in the technical specifications for either component. Consult the manufacturer's datasheet or contact the supplier for specific packaging details.

Q: What does REACH Affected versus REACH Unaffected mean?

A: REACH Affected indicates the component contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. REACH Unaffected indicates no such substances are present. Selection depends on regulatory requirements for your target market.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 7101SD9WME and 7101SD9WSE operate across -30°C to 85°C, ensuring equivalent thermal performance in the same applications.
