Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SYWME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 10.67mm length)
• Termination style (Wire Wrap)
• Panel cutout dimensions (Circular 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 Cycles)

The C&K 7201SYWSE meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7201SYWSE is the direct functional equivalent for the obsolete 7201SYWME. Both parts maintain identical electrical and mechanical specifications across all critical parameters including circuit configuration, current and voltage ratings, mounting dimensions, and operating characteristics.

The 7201SYWSE offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the 7201SYWSE achieves RoHS compliance, making it suitable for applications subject to environmental and regulatory requirements. The REACH Affected status of the 7201SYWSE indicates regulatory documentation availability for compliance-sensitive applications.

For new designs or system upgrades, the 7201SYWSE is the recommended selection. For legacy system maintenance requiring exact form-fit-function replacement, the 7201SYWSE provides complete compatibility with the original 7201SYWME specification.

Frequently Asked Questions (FAQ)

Q: Can the 7201SYWSE directly replace the 7201SYWME in existing applications?

A: Yes. The 7201SYWSE maintains identical electrical ratings (5A at 120V AC / 28V DC), circuit configuration (DPDT On-On), mechanical mounting specifications (panel mount with 6.35mm circular cutout, 1/4-40 bushing thread), actuator dimensions (10.67mm standard round), and termination style (wire wrap). No circuit modifications or panel rework are required.

Q: What is the significance of the product status difference between these parts?

A: The 7201SYWME is obsolete, indicating discontinued manufacturing and limited availability. The 7201SYWSE maintains active product status, ensuring reliable supply chain access and continued manufacturer support.

Q: How do RoHS and REACH compliance differences affect substitution?

A: The 7201SYWSE is RoHS compliant, meeting restrictions on hazardous substances in electrical and electronic equipment. The REACH Affected status indicates the part is subject to REACH chemical safety regulations. These differences are relevant for applications in regulated industries or regions with environmental compliance requirements. The 7201SYWME, being RoHS non-compliant and REACH Unaffected, may not meet current regulatory standards for new installations.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are rated for identical current (5A AC/DC), voltage (120V AC, 28V DC), electrical life (100,000 cycles), and operating temperature range (-30°C to 85°C).

Q: What inventory considerations apply to these parts?

A: The 7201SYWME has 721 pieces in stock as new original inventory. The 7201SYWSE has 689 pieces in stock as new original inventory. For long-term applications, the active status of the 7201SYWSE provides greater assurance of future availability.
