Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103P3YA3ME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type and mechanical interface (Panel Mount, Right Angle)
• Actuator specifications (Flat Anti-Rotation, 11.43mm length)
• Termination style (PC Pin)
• Panel cutout and bushing dimensions (Circular 6.35mm Dia, 1/4-40 thread)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (40,000 cycles)

The C&K 7103P3YA3SE qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7103P3YA3SE is the direct substitute for the obsolete 7103P3YA3ME. Both components maintain identical electrical and mechanical specifications, ensuring drop-in compatibility in existing designs. The 7103P3YA3SE carries active product status, providing assured long-term availability and supply chain continuity.

From a compliance perspective, the 7103P3YA3ME is RoHS3 Compliant, while the 7103P3YA3SE is RoHS Compliant. Both meet regulatory requirements for their respective classifications. The 7103P3YA3SE is REACH Affected, whereas the 7103P3YA3ME is REACH Unaffected; however, this distinction does not impact functional substitution.

For new designs or system replacements, the 7103P3YA3SE is the appropriate selection due to its active status and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the 7103P3YA3SE directly replace the 7103P3YA3ME in existing applications?

A: Yes. Both components share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (SPDT), switch function (On-Off-On), and mechanical specifications (Panel Mount, Right Angle, 11.43mm actuator, PC Pin termination). Physical dimensions and panel cutout requirements are identical, enabling direct substitution without design modification.

Q: What is the primary reason for substitution?

A: The 7103P3YA3ME is classified as obsolete. The 7103P3YA3SE is the active equivalent from the same manufacturer and series, ensuring continued availability and supply chain reliability.

Q: Are there any compliance differences between these parts?

A: Both components are RoHS compliant and carry EAR99 ECCN classification. The 7103P3YA3SE is REACH Affected while the 7103P3YA3ME is REACH Unaffected; this does not affect functional performance or substitution suitability.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by equivalence in circuit configuration (SPDT), current and voltage ratings (5A AC/DC, 120V AC, 28V DC), mounting type (Panel Mount, Right Angle), actuator specifications (Flat Anti-Rotation, 11.43mm), termination style (PC Pin), panel cutout dimensions (Circular 6.35mm Dia), bushing thread (1/4-40), operating temperature range (-30°C to 85°C), and electrical life (40,000 cycles).

Q: Is the actuator length critical for mechanical fit?

A: Yes. The 11.43mm actuator length is a fixed specification for both components. Any application requiring different actuator geometry would require evaluation of alternative part numbers within the C&K 7000 series.
