Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 7103SYW3LE is based on electrical and mechanical parameter alignment within the C&K 7000 series. The following parameters determine substitution eligibility:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current and voltage ratings (5A AC/DC, 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 (1/4-40)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)

The C&K 7103SYW3RE meets all these parameters and is classified as an active product, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7103SYW3RE is the direct active equivalent for the obsolete 7103SYW3LE. Both parts share identical electrical and mechanical specifications, ensuring functional interchangeability in panel-mount toggle switch applications requiring SPDT On-Off-On operation at 5A and 120V AC.

The 7103SYW3RE maintains RoHS compliance and is currently in active production status, providing supply continuity and long-term availability. The transition from ROHS3 to RoHS compliance in the substitute part reflects current regulatory standards without affecting electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 7103SYW3RE directly replace the 7103SYW3LE in existing designs?

A: Yes. Both parts are identical in circuit configuration, current and voltage ratings, mounting dimensions, actuator specifications, and termination style. No design modifications are required.

Q: Are there any differences in panel cutout or mounting requirements?

A: No. Both parts use identical panel cutout dimensions (Circular - 6.35mm Dia) and bushing thread specifications (1/4-40), ensuring mechanical compatibility without panel modification.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 7103SYW3RE is in active production, ensuring reliable supply and availability for new procurement. The 7103SYW3LE is no longer manufactured.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The 7103SYW3LE carries ROHS3 certification, while the 7103SYW3RE carries current RoHS certification. Both meet environmental compliance requirements for electronic components.

Q: What is the electrical life specification for these switches?

A: Both the 7103SYW3LE and 7103SYW3RE are rated for 40,000 electrical cycles, indicating equivalent operational durability.
