Substitute Part Grouping Explanation

Substitution eligibility for the EAO 732-.401-00 is determined by the following critical parameters:

  • Circuit configuration: 4PST-2NO/2NC (4 poles, single throw with 2 normally open and 2 normally closed contacts)
  • Number of positions: 3-position operation
  • Switch function: Mom-Off-Mom and Mom-On-Mom capability
  • Current rating: 5A AC minimum
  • Voltage rating: 250 VAC minimum
  • Actuator type: Flat key mechanism
  • Mounting configuration: Panel mount with solder and quick connect termination
  • Angle of throw: 60°
  • Compliance: ROHS3 and REACH requirements

The primary substitute identified is the EAO 732F.401-00, which maintains all critical electrical and functional parameters while offering improved specifications in certain mechanical aspects.

Engineering Selection Recommendations

The EAO 732F.401-00 is the direct active production substitute for the obsolete 732-.401-00. Both parts maintain identical electrical specifications, circuit configuration, and functional characteristics. The 732F.401-00 is currently in active production status with 835 pcs available in inventory, ensuring supply continuity.

Both parts comply with ROHS3 and REACH requirements, meeting current regulatory standards. The 732F.401-00 offers enhanced environmental protection (IP65 versus IP40) and improved mechanical design with reduced depth behind flange (45mm versus 54mm). The panel cutout geometry differs between models, requiring mechanical redesign consideration for panel integration.

For new designs and ongoing applications, the 732F.401-00 is the specified replacement. For legacy system maintenance where the original 732-.401-00 is currently installed, the 732F.401-00 provides functional equivalence with improved specifications, provided panel cutout modifications are feasible.

Frequently Asked Questions (FAQ)

Q: Can the 732F.401-00 directly replace the 732-.401-00 in existing installations?

A: Electrical and functional compatibility is complete. However, mechanical integration requires evaluation. The panel cutout geometry differs (square 21mm² versus circular 16mm diameter), and the depth behind flange is reduced by 9mm. Panel modifications may be necessary.

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

A: Critical parameters are: 4PST-2NO/2NC circuit configuration, 3-position operation, 5A AC current rating, 250 VAC voltage rating, flat key actuator, panel mount configuration, 60° angle of throw, and solder/quick connect termination compatibility.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The 732F.401-00 provides enhanced environmental protection (IP65 versus IP40), making it suitable for applications with higher moisture or contamination exposure.

Q: What is the inventory status for each part?

A: The obsolete 732-.401-00 has 977 pcs available. The active 732F.401-00 has 835 pcs available. The active part is recommended for new procurement.

Q: Are the termination styles compatible?

A: Yes. Both parts use identical termination: solder and quick connect 0.110" (2.8mm) connectors, ensuring circuit board and harness compatibility.
