Key Parameters

Substitute Part Grouping Explanation

The C&K 7101SY9V8SE qualifies as a direct substitute for the 7101SY9V8ME based on identical electrical and mechanical parameters. Substitution compatibility is determined by 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 specifications (Standard Round, 10.67mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 Cycles)

Both parts share the same base product number (7101SY) and feature set, confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7101SY9V8SE is the direct substitute for the obsolete 7101SY9V8ME. Both parts maintain identical electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs.

The primary distinction between the two parts is product status and regulatory compliance. The 7101SY9V8SE is an active product with ROHS3 compliance, whereas the 7101SY9V8ME is obsolete and RoHS non-compliant. For new designs or production requiring regulatory compliance with current environmental standards, the 7101SY9V8SE is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part may be used interchangeably based on availability.

Frequently Asked Questions (FAQ)

Q: Can the 7101SY9V8SE replace the 7101SY9V8ME in existing applications?

A: Yes. Both parts are electrically and mechanically identical, with matching current ratings (5A AC/DC), voltage ratings (120V AC / 28V DC), circuit configuration (SPDT), and physical specifications. Direct substitution is possible without circuit modification.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The 7101SY9V8ME is obsolete and RoHS non-compliant, while the 7101SY9V8SE is an active product with ROHS3 compliance. Electrical and mechanical performance are identical.

Q: Are there packaging differences between these parts?

A: The 7101SY9V8ME is supplied with standard packaging, while the 7101SY9V8SE is supplied in bulk packaging. This distinction affects order quantities and handling but does not impact component functionality or performance.

Q: Which part should be selected for new designs?

A: The 7101SY9V8SE should be selected for new designs, as it is an active product with current regulatory compliance (ROHS3). The 7101SY9V8ME is obsolete and should only be used for legacy system maintenance where existing inventory is available.

Q: Do these parts have the same electrical life rating?

A: Yes. Both parts are rated for 100,000 electrical cycles, ensuring equivalent operational longevity in switching applications.
