Key Parameters

Substitute Part Grouping Explanation

Substitution of the IMB25654C is based on the following critical parameters that must align between the main part and substitute candidates:

• Sensor Type: Inductive (functional equivalence)
• Sensing Distance: 0.157" (4mm) (detection range compatibility)
• Termination Style: Cable Leads (physical connection compatibility)
• RoHS Compliance: RoHS Compliant (regulatory alignment)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance)

The E2B-S08KN04-WP-C1 2M from Omron Automation and Safety meets all substitution criteria. This part maintains identical sensing distance, inductive sensor type, cable lead termination, and equivalent environmental ratings. The substitute part is active in production status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The E2B-S08KN04-WP-C1 2M is the qualified substitute for the obsolete IMB25654C. Selection is based on:

• Functional Equivalence: Both parts are inductive proximity sensors with identical 4mm sensing distance
• Regulatory Compliance: The substitute maintains RoHS compliance (ROHS3 standard) and identical ECCN/HTSUS classifications
• Production Status: The substitute is active in production, ensuring availability and supply chain stability
• Environmental Rating: Equivalent moisture sensitivity level ensures compatibility in existing environmental specifications

The substitute part provides enhanced specifications including defined output type (NPN-NO, 3-Wire), response frequency (1kHz), operating temperature range (-25°C to 70°C), IP67 ingress protection, and stainless steel body construction. These additional specifications do not conflict with the original part's application requirements and provide improved documentation for system design.

Frequently Asked Questions (FAQ)

Q: Can the E2B-S08KN04-WP-C1 2M directly replace the IMB25654C in existing installations?

A: Yes. Both sensors share identical sensing distance (4mm), inductive sensor type, and cable lead termination. The substitute part meets all core substitution parameters and maintains equivalent environmental ratings.

Q: What is the primary reason for substitution?

A: The IMB25654C is obsolete. The E2B-S08KN04-WP-C1 2M is an active production part from Omron, ensuring long-term availability and supply continuity.

Q: Are there differences in electrical specifications between these parts?

A: The substitute part provides documented electrical specifications (10V-30V supply, NPN-NO output, 1kHz response frequency) that were not specified for the original part. These specifications are standard for 4mm inductive proximity sensors and do not create incompatibility.

Q: What is the package difference?

A: The IMB25654C packaging is not specified in available documentation. The E2B-S08KN04-WP-C1 2M uses a cylinder threaded M8 package, which is standard for this sensor class and compatible with cable lead termination.

Q: Are both parts RoHS compliant?

A: Yes. The IMB25654C is RoHS Compliant. The E2B-S08KN04-WP-C1 2M is ROHS3 Compliant, representing an updated compliance standard that maintains backward compatibility.
