Key Parameters

Substitute Part Grouping Explanation

The SR125SMS4501 is identified as a direct substitute for the SR125SMS00 based on the following alignment criteria:

Manufacturer Consistency: Both parts are manufactured by Omron Automation and Safety, ensuring design philosophy and quality standards alignment.

Electrical Specifications: The substitute maintains 24VDC coil voltage operation, matching the primary electrical requirement of the original component.

Relay Classification: Both components function as safety relays within the SR125SMS series, confirming functional category equivalence.

Regulatory Compliance: Identical ECCN (EAR99) and HTSUS (8536.41.0020) classifications confirm regulatory and trade compliance parity.

Environmental Rating: Both parts share MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent environmental tolerance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SR125SMS4501 is the designated equivalent for SR125SMS00 applications. Both components share identical manufacturer origin, regulatory classification, and environmental ratings. The substitute provides documented contact specifications (DPST-NO/NC, 1.5A) and DIN Rail mounting capability, supporting standard industrial control panel integration.

Obsolescence Consideration: Both the original and substitute parts carry obsolete product status. Component selection should prioritize current inventory availability. The SR125SMS4501 maintains 994 units in stock against 1142 units of the original part, providing adequate supply for near-term requirements.

Compliance Alignment: Identical ECCN and HTSUS classifications confirm that substitution does not introduce regulatory or trade compliance complications. Both parts maintain MSL 1 rating, eliminating moisture sensitivity concerns in standard industrial environments.

Frequently Asked Questions (FAQ)

Q: Can SR125SMS4501 directly replace SR125SMS00 in existing installations?

A: Yes. Both components are manufactured by Omron Automation and Safety with matching 24VDC coil voltage, identical regulatory classifications (ECCN EAR99, HTSUS 8536.41.0020), and equivalent environmental ratings (MSL 1). The substitute is the documented equivalent for this application.

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

A: Coil voltage (24VDC), manufacturer consistency (Omron), relay classification (safety relay), and contact specifications determine substitution validity. The SR125SMS4501 provides DPST-NO/NC contact configuration with 1.5A rating and 24VDC switching capability.

Q: Are there packaging or mounting differences between these parts?

A: The SR125SMS4501 is specified for DIN Rail mounting with screw terminal termination. The original SR125SMS00 mounting configuration is not documented in available specifications. Verify mechanical fit requirements against your control panel design before final selection.

Q: What is the inventory status for these components?

A: SR125SMS00 has 1142 units in stock; SR125SMS4501 has 994 units in stock. Both are classified as new original inventory. Confirm availability with your supplier for production quantities.

Q: Do both parts share the same regulatory compliance?

A: Yes. Both components carry identical ECCN (EAR99) and HTSUS (8536.41.0020) classifications, confirming equivalent regulatory and trade compliance status.
