Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103SD9AV2ME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole, Right Angle, Vertical)
• Actuator specifications (Standard Round, 12.45mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles)
• Base product number (7103SD)

The C&K 7103SD9AV2SE meets all these criteria while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 7103SD9AV2SE is a direct functional equivalent to the 7103SD9AV2ME with identical electrical and mechanical specifications. The primary distinction is product status: the 7103SD9AV2SE is active and carries RoHS compliance certification, whereas the 7103SD9AV2ME is obsolete and RoHS non-compliant. For new designs and ongoing production requiring SPDT toggle switches with 5A/120V AC ratings and through-hole vertical mounting, the 7103SD9AV2SE is the appropriate selection. Both parts share identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the 7103SD9AV2SE be used as a direct replacement for the 7103SD9AV2ME in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including current rating, voltage rating, mounting configuration, actuator dimensions, and operating temperature range. PCB layout and mechanical mounting require no modification.

Q: What is the significance of the RoHS compliance difference?

A: The 7103SD9AV2SE is RoHS compliant, meeting EU Directive 2011/65/EU restrictions on hazardous substances. The 7103SD9AV2ME is non-compliant. For applications subject to RoHS requirements or future regulatory compliance, the 7103SD9AV2SE is mandatory.

Q: Are there inventory considerations between these parts?

A: The 7103SD9AV2ME has 1,075 pieces in stock (obsolete status), while the 7103SD9AV2SE has 648 pieces available (active status). For long-term supply chain planning, the active status of 7103SD9AV2SE provides greater availability assurance.

Q: Do these parts share the same base product number?

A: Yes. Both parts reference base product number 7103SD, confirming they belong to the same product family and design generation.

Q: Are there any electrical performance differences?

A: No. Both parts maintain identical electrical life (40,000 cycles), current capacity (5A AC/DC), voltage ratings (120V AC, 28V DC), and operating temperature range (-30°C to 85°C).
