Engineering Selection Recommendations

The OMI-SH-112LM,394 is electrically and mechanically equivalent to the OMI-SH-112LM,094 across all functional parameters. Both parts are classified as obsolete products from the same manufacturer and series.

Compliance Consideration:

The primary distinction between these parts is RoHS compliance status. The OMI-SH-112LM,094 carries RoHS3 compliance certification, while the OMI-SH-112LM,394 is RoHS non-compliant. Selection between these substitutes must account for the regulatory and compliance requirements of the target application and end-use market.

For applications subject to RoHS3 requirements, the OMI-SH-112LM,094 is the appropriate selection. For applications without RoHS compliance mandates, either part satisfies the functional specification.

Packaging Consideration:

The OMI-SH-112LM,394 is supplied in tube packaging, while the OMI-SH-112LM,094 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance and may be selected based on inventory management and handling requirements.

Frequently Asked Questions (FAQ)

Q: Are the OMI-SH-112LM,094 and OMI-SH-112LM,394 electrically interchangeable?

A: Yes. Both relays share identical electrical specifications including 12VDC coil voltage, 10A contact rating, 250VAC/30VDC switching voltage, 45mA coil current, and 270 Ohm coil resistance. They operate within the same temperature range and timing parameters.

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

A: The primary differences are packaging format (bulk versus tube) and RoHS compliance status. The OMI-SH-112LM,094 is RoHS3 compliant, while the OMI-SH-112LM,394 is RoHS non-compliant. All functional and mechanical parameters are identical.

Q: Can I use the OMI-SH-112LM,394 in place of the OMI-SH-112LM,094?

A: Functional substitution is valid when RoHS compliance is not a requirement. If the application or end market mandates RoHS3 compliance, the OMI-SH-112LM,094 must be used.

Q: Do these relays have the same mounting footprint?

A: Yes. Both relays feature through-hole mounting with PC pin termination, ensuring identical PCB footprint compatibility.

Q: What is the operating temperature range for these relays?

A: Both relays operate across -30°C to 70°C, supporting applications in standard industrial and commercial temperature environments.

Q: Are both parts still in production?

A: No. Both the OMI-SH-112LM,094 and OMI-SH-112LM,394 carry obsolete product status. Availability is limited to existing inventory from authorized distributors.
