ARXP1106 Equivalent & Substitute Parts Reference

Part Overview

The ARXP1106 is a latching single-coil relay manufactured by Panasonic Electric Works, designed for RF applications with SPDT contact configuration and 500 mA contact rating at 6VDC coil voltage. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ARXP1106 is constrained by the following critical parameters:

Contact Configuration: SPDT (1 Form C) contact form is mandatory for functional equivalence in switching applications requiring single-pole double-throw topology.

Contact Rating: 500 mA current rating establishes the maximum load capacity. Substitute parts must meet or exceed this specification.

Coil Voltage & Actuation: The 6VDC coil voltage with 4.5VDC must-operate threshold defines the control signal requirements. Substitute parts operating at different coil voltages require circuit redesign.

Coil Type Architecture: The latching mechanism with single-coil design is application-specific. Dual-coil latching relays introduce different control logic requirements.

Mounting & Termination: Through-hole PC pin termination is specific to PCB layout and assembly processes. Surface-mount alternatives require board redesign.

The ARN12A4H substitute presents functional differences in coil architecture (dual-coil latching), coil voltage (4.5VDC), mounting type (surface mount), and termination style (gull wing), indicating this part is not a direct pin-compatible or functional equivalent for existing ARXP1106 applications.

Parameter Comparison

Engineering Selection Recommendations

The ARN12A4H is an active-production relay from the same manufacturer with identical contact form (SPDT) and contact material (gold plating). However, direct substitution in existing ARXP1106 applications is not supported due to fundamental architectural and electrical differences:

Coil Architecture Mismatch: The ARXP1106 uses single-coil latching design, while ARN12A4H employs dual-coil latching. This requires different control signal sequencing and driver circuitry.

Voltage & Current Incompatibility: The 6VDC coil voltage of ARXP1106 differs from the 4.5VDC requirement of ARN12A4H. Additionally, ARN12A4H draws 88.9 mA compared to 33.3 mA for ARXP1106, requiring higher-capacity drive circuits.

Form Factor Incompatibility: Through-hole PC pin termination (ARXP1106) is not compatible with surface-mount gull-wing leads (ARN12A4H). PCB layout and assembly process changes are required.

Compliance Status: ARN12A4H holds active product status with RoHS compliance certification, whereas ARXP1106 is obsolete. For new designs or system upgrades, ARN12A4H represents current manufacturing availability.

For applications requiring functional equivalence to ARXP1106 specifications, consultation with Panasonic Electric Works technical support is necessary to identify through-hole latching single-coil relays with 6VDC coil voltage and 500 mA contact rating.

Frequently Asked Questions (FAQ)

Q: Can ARN12A4H directly replace ARXP1106 in existing circuit boards?

A: No. ARN12A4H uses surface-mount gull-wing termination while ARXP1106 uses through-hole PC pins. Physical mounting is incompatible without PCB redesign. Additionally, the dual-coil latching architecture requires different control logic than the single-coil design of ARXP1106.

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

A: ARXP1106 operates at 6VDC with 33.3 mA coil current and 200 mW power consumption. ARN12A4H operates at 4.5VDC with 88.9 mA coil current and 400 mW power consumption. The coil resistance differs significantly (180 Ohms vs. 50.6 Ohms), affecting driver circuit design.

Q: Why does ARN12A4H have faster switching times?

A: ARN12A4H operates in 5 ms for both operate and release cycles, compared to 10 ms for ARXP1106. This is a characteristic of the dual-coil latching architecture and different magnetic design, not a direct performance upgrade.

Q: Is ARN12A4H RoHS compliant?

A: Yes, ARN12A4H is RoHS compliant. ARXP1106 product status documentation does not specify RoHS compliance. For applications requiring RoHS certification, ARN12A4H meets this requirement.

Q: What is the contact rating difference?

A: ARXP1106 specifies 500 mA contact rating. ARN12A4H contact rating is not provided in available specifications. Contact rating verification with manufacturer documentation is necessary before application selection.

Q: Can I use ARN12A4H in a new design if I modify the circuit?

A: ARN12A4H is suitable for new designs requiring SPDT latching relay functionality with 4.5VDC coil voltage and surface-mount assembly. Circuit design must accommodate dual-coil latching control logic, higher coil current requirements, and the specified gull-wing termination footprint.

Q: What is the operating temperature difference?

A: ARXP1106 operates from -40°C to 70°C. ARN12A4H operates from -40°C to 85°C, providing a 15°C higher maximum temperature rating. For applications requiring extended high-temperature operation, ARN12A4H offers broader environmental capability.
