OMI-SH-112LM,601 Equivalent & Substitute Parts

Part Overview

The OMI-SH-112LM,601 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays. This SPST-NO (1 Form A) relay operates at 12VDC with a 10A contact rating and is designed for through-hole mounting applications. The product is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design and procurement requirements. Substitute parts must maintain functional compatibility across coil voltage, contact form, mounting type, and electrical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OMI-SH-112LM,601 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or exceed the original specification:

Critical Matching Parameters:

• Coil voltage: 12VDC
• Contact form: SPST-NO (1 Form A)
• Mounting type: Through Hole
• Termination style: PC Pin
• Coil type: Non Latching
• Seal rating: Sealed - Fully
• Contact material: Silver Tin Oxide (AgSnO)

Parameters Allowed to Exceed Original Specification:

• Contact rating current (minimum 10A required)
• Switching voltage (minimum 250VAC, 30VDC required)
• Operating temperature range (minimum -30°C ~ 70°C required)

The JVN1A-12V-F meets all critical matching parameters and exceeds performance specifications in contact rating (16A vs. 10A), switching voltage (277VAC vs. 250VAC), and operating temperature range (-40°C ~ 70°C vs. -30°C ~ 70°C).

Parameter Comparison

Engineering Selection Recommendations

The JVN1A-12V-F is a direct functional substitute for the obsolete OMI-SH-112LM,601. Both components are ROHS3 compliant and carry MSL rating of 1 (Unlimited), meeting environmental and regulatory requirements.

The JVN1A-12V-F offers performance advantages over the original specification:

• Higher contact current rating (16A vs. 10A) provides additional margin for load applications
• Improved switching voltage capability (277VAC vs. 250VAC) extends application range
• Reduced coil current consumption (16.7 mA vs. 45 mA) decreases power supply requirements
• Faster switching times (12 ms operate, 5 ms release vs. 20 ms operate, 8 ms release) improve response characteristics
• Extended operating temperature range (-40°C ~ 70°C vs. -30°C ~ 70°C) supports broader environmental conditions

The substitute part maintains identical electrical characteristics for coil voltage, contact form, mounting configuration, and termination style. The JVN1A-12V-F is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the JVN1A-12V-F directly replace the OMI-SH-112LM,601 in existing designs?

A: Yes. Both relays share identical coil voltage (12VDC), contact form (SPST-NO), mounting type (through hole), and termination style (PC pin). The substitute meets or exceeds all critical electrical parameters required for functional compatibility.

Q: What are the key differences between these two relays?

A: The primary differences are contact current rating (16A vs. 10A), switching voltage (277VAC vs. 250VAC), coil current consumption (16.7 mA vs. 45 mA), switching times (12 ms/5 ms vs. 20 ms/8 ms), and operating temperature range (-40°C ~ 70°C vs. -30°C ~ 70°C). All differences favor the substitute part.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both components are ROHS3 compliant with MSL rating of 1 (Unlimited). The substitute maintains equivalent environmental and regulatory compliance.

Q: Does the lower coil current of the JVN1A-12V-F affect circuit design?

A: The reduced coil current (16.7 mA vs. 45 mA) decreases power supply requirements and reduces heat generation. Existing circuit designs will function correctly with the substitute part. No circuit modifications are required.

Q: Are the switching times of the JVN1A-12V-F compatible with timing-sensitive applications?

A: The JVN1A-12V-F operates faster than the original (12 ms operate, 5 ms release vs. 20 ms operate, 8 ms release). Applications designed for the OMI-SH-112LM,601 timing specifications will function correctly with the faster substitute. Applications requiring specific timing characteristics should verify compatibility with the faster response times.

Q: What is the availability status of the JVN1A-12V-F?

A: The JVN1A-12V-F is in active production status with current inventory of 2533 pieces. The OMI-SH-112LM,601 is obsolete with no ongoing production.
