Omron MY4-02 DC6 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY4-02 DC6 is a general purpose 4PDT (4 Form C) relay with a 6VDC coil, rated for 3A contact current, and designed for through-hole mounting. This relay is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. The MY4-02 DC6 remains in stock inventory but requires alternative solutions for long-term component sourcing and system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Omron MY4-02 DC6 is determined by the following critical parameters:

Primary Substitution Criteria:

• Coil voltage: 6VDC (exact match required)
• Contact form: 4PDT (4 Form C) configuration (exact match required)
• Mounting type: Through hole (exact match required)
• Termination style: PC Pin (exact match required)
• Coil type: Non latching (exact match required)

Secondary Compatibility Parameters:

• Contact rating current: Minimum 3A (equal or higher acceptable)
• Switching voltage: Minimum 250VAC capability (equal or higher acceptable)
• Coil current: 150 mA (standard for this class)
• Coil resistance: 40 Ohms (standard for this class)
• Operating temperature range: Must encompass application requirements

The TE Connectivity Potter & Brumfield KHAE-17D12-6 meets all primary substitution criteria and exceeds secondary parameters, qualifying as a direct substitute for the obsolete Omron MY4-02 DC6.

Engineering Selection Recommendations

The TE Connectivity KHAE-17D12-6 is the qualified substitute for the obsolete Omron MY4-02 DC6 based on the following engineering factors:

Product Status Alignment: The KHAE-17D12-6 maintains active product status with current manufacturing and inventory availability (861 pcs in stock), ensuring long-term component sourcing compared to the obsolete MY4-02 DC6.

Compliance and Certifications: Both relays maintain RoHS compliance. The KHAE-17D12-6 achieves ROHS3 compliance, meeting current regulatory requirements. Both components carry EAR99 ECCN classification and identical HTSUS codes (8536.41.0020), confirming regulatory equivalence.

Electrical Performance: The KHAE-17D12-6 provides superior electrical characteristics with 5A contact rating versus 3A, lower must-operate voltage (4.5VDC vs 4.8VDC), and faster switching times (13ms operate, 6ms release vs 20ms each). These improvements enhance system reliability and response performance.

Mechanical and Functional Compatibility: All critical parameters align: 6VDC coil voltage, 4PDT contact configuration, through-hole mounting, PC pin termination, 150mA coil current, and 40-ohm coil resistance. The KHAE-17D12-6 is a direct functional replacement.

Temperature Consideration: The KHAE-17D12-6 operating range (-45°C ~ 70°C) is narrower than the MY4-02 DC6 (-55°C ~ 70°C). Applications requiring operation below -45°C require evaluation of alternative substitutes or retention of original stock.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity KHAE-17D12-6 directly replace the Omron MY4-02 DC6 in existing designs?

A: Yes, the KHAE-17D12-6 is a direct functional replacement. All primary electrical and mechanical parameters match: 6VDC coil, 4PDT contact form, 3A minimum current rating (KHAE-17D12-6 rated 5A), through-hole mounting, and PC pin termination. Physical footprint and pin configuration compatibility must be verified against PCB layout documentation.

Q: What is the difference in contact material between these relays?

A: The Omron MY4-02 DC6 uses pure silver (Ag) contacts, while the TE Connectivity KHAE-17D12-6 uses silver cadmium oxide (AgCdO) contacts. AgCdO provides enhanced arc suppression and contact wear resistance, particularly beneficial in switching applications with inductive loads.

Q: Are there temperature range limitations when substituting?

A: The KHAE-17D12-6 operates from -45°C to 70°C, compared to the MY4-02 DC6 range of -55°C to 70°C. Applications requiring operation below -45°C must retain the original Omron component or identify alternative substitutes with extended low-temperature ratings.

Q: How do the switching times compare?

A: The KHAE-17D12-6 operates faster: 13ms operate time and 6ms release time versus 20ms for both parameters on the MY4-02 DC6. This faster response improves system switching performance and may reduce power dissipation in high-frequency switching applications.

Q: What packaging considerations apply to the KHAE-17D12-6?

A: The KHAE-17D12-6 is supplied in bulk packaging, whereas the MY4-02 DC6 packaging specification is not provided. Verify packaging requirements for your procurement and assembly processes.

Q: Are both relays RoHS compliant?

A: Yes. The Omron MY4-02 DC6 is RoHS compliant, and the TE Connectivity KHAE-17D12-6 is ROHS3 compliant. Both meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the coil current requirement for both relays?

A: Both relays require 150mA coil current at 6VDC, with identical 40-ohm coil resistance. Power supply and control circuit designs remain unchanged when substituting.
