Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: circuit configuration (4PDT), switch function (On-On), mounting type (through-hole right-angle vertical), actuator type and length (standard round, 5.08mm), termination style (PC pin), and operating temperature range compatibility. Voltage and current ratings define application scope; parts with equal or higher ratings in both AC and DC domains are direct substitutes. Parts with different voltage or current ratings are classified as similar alternatives and require application-level verification.

Direct Substitute Criteria:

• Identical circuit, mounting, actuator, and termination specifications
• Equal or higher voltage and current ratings
• Compatible operating temperature range

Similar Alternative Criteria:

• Identical circuit, mounting, actuator, and termination specifications
• Voltage or current ratings differ from main part
• Compatible operating temperature range

Parameter Comparison

Engineering Selection Recommendations

7401MY9AV2SE (C&K Direct Substitute): This part is the primary replacement for the obsolete 7401MY9AV2ME. It maintains identical electrical ratings (5A at 120V AC), mechanical configuration, and operating temperature range. The part is active in production with ROHS3 compliance. REACH status differs (REACH Affected vs. REACH Unaffected); verify REACH compliance requirements for your application jurisdiction.

34A4P12B4M7GT (Grayhill Inc. Similar Alternative): This part matches all mechanical and circuit specifications with equivalent current rating (5A AC/DC) and slightly higher AC voltage rating (125V vs. 120V). Electrical life is reduced to 40,000 cycles compared to 100,000 cycles in the main part. Use this alternative only in applications where the reduced cycle life is acceptable. Product is active and ROHS3 compliant.

A423M1D9AV2B (Electroswitch Similar Alternative): This part has significantly reduced current rating (0.5VA vs. 5A) and AC voltage rating (28V vs. 120V). Use only in low-power applications operating at 28V AC or lower. Electrical life is 60,000 cycles. Product is active and RoHS compliant.

A423M1D9AV2Q (Electroswitch Similar Alternative): This part has higher current rating (6A vs. 5A) and higher AC voltage rating (125V vs. 120V), making it suitable for applications requiring greater electrical capacity. Electrical life is 60,000 cycles. Product is active and RoHS compliant.

Frequently Asked Questions (FAQ)

Q: Can I use 7401MY9AV2SE as a direct replacement for 7401MY9AV2ME?

A: Yes. The 7401MY9AV2SE is a direct substitute with identical electrical ratings (5A at 120V AC), mechanical configuration (through-hole right-angle vertical), and operating temperature range (-30°C to 85°C). The primary difference is product status (active vs. obsolete) and REACH compliance classification.

Q: What is the difference between direct and similar alternatives?

A: Direct alternatives maintain all electrical and mechanical specifications of the main part. Similar alternatives share the same circuit configuration and mechanical form factor but differ in voltage or current ratings. Similar alternatives require application-level verification to confirm suitability.

Q: Can I use A423M1D9AV2B in a 120V AC application?

A: No. The A423M1D9AV2B is rated for 28V AC maximum. Using it in a 120V AC application exceeds its voltage rating and will cause failure.

Q: Why does 34A4P12B4M7GT have lower electrical life than the main part?

A: The 34A4P12B4M7GT is rated for 40,000 cycles compared to 100,000 cycles for the 7401MY9AV2ME. This is a design characteristic of the Grayhill part. Verify that your application's cycle requirements do not exceed 40,000 cycles before selecting this alternative.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are RoHS compliant (either RoHS or ROHS3). Verify REACH compliance status for your specific application and jurisdiction, as REACH classifications vary between manufacturers.

Q: What mounting considerations apply to these substitutes?

A: All substitute parts use identical through-hole, right-angle vertical mounting with standard round actuators of 5.08mm length and PC pin termination. No mechanical redesign is required for PCB integration.
