Key Parameters

Substitute Part Grouping Explanation

Substitution of the Coto Technology 2920-05-111 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Contact form: SPST-NO (1 Form A)
• Coil voltage: 5VDC
• Contact current rating: 1 A minimum
• Mounting type: Through Hole
• Termination style: PC Pin
• Coil type: Non Latching

Acceptable Parameter Variations: Substitute parts may exceed the original specifications in switching voltage rating, coil current efficiency, operating temperature range, and switching speed, provided the minimum requirements are met or exceeded. Enhanced performance characteristics do not compromise backward compatibility in circuit applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The Standex-Meder Electronics SHV05-1A85-78L3K serves as a direct functional equivalent to the obsolete Coto Technology 2920-05-111. Both components share identical contact configuration, coil voltage, and current rating specifications. The substitute part maintains active product status, ensuring long-term availability and supply chain continuity.

The SHV05-1A85-78L3K demonstrates enhanced performance characteristics across multiple parameters: doubled switching voltage capability (1000VAC/1000VDC versus 500VAC/500VDC), reduced coil current draw (27.8 mA versus 66.7 mA), faster release time (0.1 ms versus 1 ms), and extended operating temperature range (-40°C to 100°C versus -20°C to 85°C). These improvements provide superior reliability margins without introducing compatibility issues in applications designed for the original part.

Both components maintain equivalent regulatory compliance: RoHS compliance (ROHS3 for the substitute), REACH unaffected status, and identical ECCN and HTSUS classifications. Moisture sensitivity levels are identical at MSL 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the Standex-Meder Electronics SHV05-1A85-78L3K directly replace the Coto Technology 2920-05-111 in existing circuit designs?

A: Yes. Both relays share identical contact form (SPST-NO), coil voltage (5VDC), current rating (1A), mounting type (Through Hole), and termination style (PC Pin). The substitute part meets or exceeds all minimum electrical specifications of the original component.

Q: What are the primary differences between these two relay models?

A: The substitute part offers enhanced switching voltage rating (1000VAC/1000VDC versus 500VAC/500VDC), lower coil current consumption (27.8 mA versus 66.7 mA), faster switching response (1.1 ms operate time, 0.1 ms release time versus 1.5 ms and 1 ms respectively), and wider operating temperature range (-40°C to 100°C versus -20°C to 85°C). Coil resistance differs (180 Ohms versus 75 Ohms) due to design optimization.

Q: Are there packaging differences between the original and substitute parts?

A: The Coto Technology 2920-05-111 is supplied in standard packaging, while the Standex-Meder Electronics SHV05-1A85-78L3K is packaged in Tube format. Both utilize identical PC Pin termination for through-hole PCB mounting, ensuring mechanical compatibility.

Q: Do both relays require identical coil drive circuitry?

A: The substitute part operates at the same 5VDC coil voltage as the original. However, the reduced coil current requirement (27.8 mA versus 66.7 mA) may allow for lower-power drive circuits. Existing drive circuits designed for the original part will function with the substitute without modification.

Q: What is the regulatory compliance status of the substitute part?

A: The Standex-Meder Electronics SHV05-1A85-78L3K maintains ROHS3 compliance, REACH unaffected status, and identical ECCN (EAR99) and HTSUS (8536.41.0030) classifications as the original component. Both components have MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Why is the original Coto Technology part classified as obsolete?

A: The Coto Technology 2920-05-111 is no longer in active production. The Standex-Meder Electronics SHV05-1A85-78L3K remains in active production status, providing assured long-term availability for new designs and replacement applications.
