Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103P3DA3ME 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, 13.21mm 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 7103P3DA3SE qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters within the 7000 series family.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7103P3DA3SE is the direct equivalent for the obsolete 7103P3DA3ME. Both components maintain identical electrical performance specifications and mechanical interfaces. The primary distinction is product status: the 7103P3DA3SE is currently in active production, ensuring supply chain availability and long-term support.

From a compliance perspective, both parts meet RoHS requirements. The 7103P3DA3ME carries ROHS3 certification, while the 7103P3DA3SE carries standard RoHS compliance. Both are classified as REACH Unaffected or REACH Affected respectively, with no impact on component functionality or substitution eligibility.

For applications requiring the 7103P3DA3ME, transition to the 7103P3DA3SE provides equivalent performance with improved availability and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the 7103P3DA3SE directly replace the 7103P3DA3ME in existing designs?

A: Yes. Both components share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (SPDT), and mechanical specifications (panel mount, right angle, 13.21mm actuator, PC pin termination, 1/4-40 bushing thread). No circuit modifications or mechanical adjustments are required.

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

A: The primary difference is product status. The 7103P3DA3ME is obsolete, while the 7103P3DA3SE is in active production. Both maintain the same functional and physical specifications within the C&K 7000 series.

Q: Are there any compliance differences between these parts?

A: Both parts comply with RoHS standards and carry EAR99 export classification. The 7103P3DA3ME is ROHS3 compliant, and the 7103P3DA3SE is RoHS compliant. REACH status differs (Unaffected vs. Affected), but this does not affect component performance or substitution suitability.

Q: What parameters must remain constant for a valid substitute?

A: Valid substitutes must maintain identical specifications for circuit configuration (SPDT), current rating (5A AC/DC), voltage ratings (120V AC, 28V DC), mounting type (panel mount, right angle), actuator specifications (flat anti-rotation, 13.21mm), termination style (PC pin), and panel interface dimensions (6.35mm circular cutout, 1/4-40 thread).

Q: Is the 7103P3DA3SE available in the same packaging as the 7103P3DA3ME?

A: Both components use identical panel mount, right angle mechanical packaging. No packaging conversion or adaptation is necessary for direct substitution.
