Key Parameters

Substitute Part Grouping Explanation

The MY4-GS-R DC100/110 qualifies as a direct substitute based on the following critical parameters:

Matching Electrical Characteristics:

• Identical coil voltage: 110VDC
• Identical contact form: 4PDT (4 Form C)
• Identical switching voltage rating: 250VAC, 220VDC - Max
• Identical coil type: Non Latching
• Same relay classification: General Purpose

Mechanical Compatibility: The substitute part differs in mounting configuration (socketable vs. standard mounting), but this represents an enhancement rather than a limitation, as socketable designs provide improved field serviceability and standardized connection interfaces.

Compliance Alignment: Both parts maintain RoHS compliance, ensuring regulatory consistency in component selection.

Parameter Comparison

Engineering Selection Recommendations

The MY4-GS-R DC100/110 is the appropriate substitute for the obsolete MY4-GS DC100/110 based on the following factors:

Product Status Alignment: The substitute part maintains active product status with Omron, ensuring continued availability and manufacturing support. The original part's obsolete classification necessitates transition to an actively supported equivalent.

Regulatory Compliance: Both parts maintain RoHS compliance. The substitute achieves ROHS3 compliance, representing current regulatory standards. This upgrade ensures compatibility with modern procurement and environmental requirements.

Electrical Equivalence: All critical electrical parameters—coil voltage, contact configuration, switching voltage rating, and coil type—are identical between the main part and substitute. This ensures functional interchangeability in existing circuit designs.

Enhanced Specifications: The substitute part provides documented electrical characteristics (coil current, contact rating, operating voltage thresholds, timing parameters) that were not specified for the original part, enabling more precise circuit analysis and design validation.

Frequently Asked Questions (FAQ)

Q: Can the MY4-GS-R DC100/110 directly replace the MY4-GS DC100/110 in existing applications?

A: Yes. Both relays share identical coil voltage (110VDC), contact configuration (4PDT), switching voltage rating (250VAC, 220VDC - Max), and coil type (Non Latching). The electrical function is equivalent.

Q: What is the primary difference between these two relay models?

A: The MY4-GS-R DC100/110 features socketable mounting with standardized quick-connect termination (0.110" / 2.8mm), whereas the original MY4-GS DC100/110 mounting configuration is not specified. The socketable design provides improved field serviceability.

Q: Why is the original MY4-GS DC100/110 classified as obsolete?

A: Product obsolescence reflects Omron's discontinuation of this model line. The MY4-GS-R DC100/110 represents the current active equivalent within the same product family.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant. The substitute achieves ROHS3 compliance, which represents the current regulatory standard. This upgrade ensures alignment with modern environmental and procurement requirements.

Q: What are the operating voltage thresholds for the substitute relay?

A: The MY4-GS-R DC100/110 must operate at a minimum of 88 VDC and must release at a maximum of 11 VDC. These parameters define the voltage window for reliable relay operation.

Q: Is the socketable mounting of the substitute part compatible with the original application?

A: Socketable mounting is compatible with applications using standard relay sockets designed for 0.110" (2.8mm) quick-connect terminals. If the original application uses hardwired connections, mechanical adaptation may be required.
