ARX1006 Equivalent & Substitute Parts

Part Overview

The ARX1006 is a non-latching RF relay manufactured by Panasonic Electric Works, designed for 6VDC coil operation with SPDT contact configuration and 500mA contact rating. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The relay operates across a temperature range of -40°C to 70°C with gold-plated contacts and through-hole PC pin termination.

Substitute Part Grouping Explanation

Substitution of the ARX1006 is determined by the following critical parameters that must remain compatible:

Coil Voltage: 6VDC operation is mandatory for direct replacement without circuit modification
Contact Form: SPDT (1 Form C) configuration must be maintained for signal routing compatibility
Coil Activation Thresholds: Must Operate Voltage (4.5 VDC) and Must Release Voltage (0.6 VDC) ensure proper circuit behavior
Contact Rating: Minimum 500mA current handling capability required for load compatibility
Switching Voltage: Maximum 30VDC switching capability must be supported

The substitute part 1-1462051-7 (TE Connectivity Potter & Brumfield HF3/AXICOM series) meets these core substitution criteria while offering enhanced performance characteristics in contact rating, switching voltage capability, and operating temperature range.

Engineering Selection Recommendations

The 1-1462051-7 substitute part is functionally compatible with the ARX1006 for coil activation, contact switching, and electrical load handling. The substitute demonstrates superior performance across multiple parameters: lower coil current draw (23.3mA vs 33.3mA), higher contact current rating (2A vs 500mA), faster switching times (5ms vs 10ms operate time), and extended operating temperature range (-55°C to 85°C vs -40°C to 70°C).

The substitute part carries Active product status and ROHS3 compliance, providing long-term availability and regulatory alignment compared to the obsolete ARX1006.

Critical consideration: The 1-1462051-7 uses surface mount termination (Gull Wing) versus the ARX1006 through-hole PC pin configuration. Direct socket replacement is not possible; PCB redesign is required to accommodate the different mounting and termination style.

Frequently Asked Questions (FAQ)

Q: Can the 1-1462051-7 directly replace the ARX1006 without PCB modification?

A: No. While electrically compatible, the 1-1462051-7 uses surface mount Gull Wing termination compared to the ARX1006 through-hole PC pin configuration. PCB layout redesign is necessary.

Q: Are the coil activation voltages identical between these parts?

A: Yes. Both parts operate at 6VDC coil voltage with identical Must Operate Voltage (4.5VDC) and Must Release Voltage (0.6VDC) thresholds, ensuring equivalent circuit behavior.

Q: Does the higher contact rating of the 1-1462051-7 affect compatibility?

A: No. The substitute's 2A contact rating exceeds the ARX1006 requirement of 500mA. This provides additional design margin and does not compromise compatibility.

Q: What is the impact of the different coil resistance values?

A: The 1-1462051-7 has 257 Ohms coil resistance versus 180 Ohms for the ARX1006. At 6VDC, this results in lower coil current (23.3mA vs 33.3mA), reducing power consumption and heat generation while maintaining reliable operation.

Q: Are there temperature range considerations for substitution?

A: The 1-1462051-7 operates across -55°C to 85°C, which encompasses the ARX1006 range of -40°C to 70°C. The substitute is suitable for applications requiring the original temperature specification and extends capability for wider temperature environments.

Q: How do the switching time differences affect circuit performance?

A: The 1-1462051-7 operates faster (5ms vs 10ms) and releases faster (5ms vs 6ms). For most applications, faster switching improves response time. Verify timing-critical circuits do not depend on the original relay's slower response characteristics.
