ARXP1006 Equivalent & Substitute Parts Reference

Part Overview

The ARXP1006 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 industrial temperature ranges and features gold-plated contacts suitable for RF applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ARXP1006 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Coil voltage: 6VDC (exact match required)
• Contact form: SPDT (1 Form C) configuration
• Must operate voltage: 4.5 VDC minimum
• Must release voltage: 0.6 VDC maximum
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• Contact rating current: Equal to or greater than 500mA
• Switching voltage: Equal to or greater than 30VDC
• Operating temperature range: May extend beyond -40°C ~ 70°C
• Coil current: May vary within design tolerance
• Operate/release time: May vary within application requirements
• Mounting type and termination style: May differ based on PCB design accommodation
• Contact material composition: May vary if performance specifications are maintained

The substitute part 1-1462051-7 meets all mandatory criteria while exceeding contact rating and switching voltage specifications.

Engineering Selection Recommendations

The 1-1462051-7 (TE Connectivity Potter & Brumfield HF3/AXICOM series) is a qualified substitute for the obsolete ARXP1006. Selection is based on the following factors:

Product Status Consideration: The ARXP1006 is obsolete, while the 1-1462051-7 maintains active product status with current manufacturing support and documented availability.

Compliance and Certification: Both components share identical moisture sensitivity classification (MSL 1 - Unlimited) and ECCN designation (EAR99). The 1-1462051-7 carries RoHS3 compliance and REACH unaffected status, providing regulatory alignment for modern applications.

Electrical Compatibility: The substitute meets all critical electrical parameters including 6VDC coil operation, SPDT contact configuration, and threshold voltage requirements (4.5VDC operate, 0.6VDC release). The substitute's higher contact rating (2A versus 500mA) and extended switching voltage capability (220VDC versus 30VDC) provide design margin without functional compromise.

Mechanical Accommodation: The substitute transitions from through-hole PC pin termination to surface-mount gull-wing configuration. PCB redesign is required to accommodate this change.

Thermal Performance: The substitute's extended operating temperature range (-55°C ~ 85°C versus -40°C ~ 70°C) supports broader environmental applications.

Frequently Asked Questions (FAQ)

Q: Can the 1-1462051-7 directly replace the ARXP1006 without circuit modification?

A: Electrical substitution is valid. The 6VDC coil voltage, SPDT contact configuration, and threshold voltages are identical. However, the termination style differs (surface mount gull wing versus through-hole PC pin), requiring PCB layout modification.

Q: What is the significance of the lower coil current in the substitute (23.3mA versus 33.3mA)?

A: The substitute requires less coil current while maintaining identical operate and release voltage thresholds. This represents improved efficiency and reduced power dissipation (140mW versus 200mW). Existing drive circuits designed for 33.3mA will operate the substitute without issue.

Q: Does the higher contact rating of the 1-1462051-7 (2A versus 500mA) affect compatibility?

A: No. Higher contact rating provides design margin and does not compromise compatibility. The substitute can safely handle all load conditions within the original 500mA specification.

Q: Are there temperature range implications for substitution?

A: The substitute's extended operating range (-55°C ~ 85°C) exceeds the original specification (-40°C ~ 70°C). Applications operating within the original temperature envelope experience no adverse effects. Applications requiring extended temperature operation benefit from the substitute's broader capability.

Q: What is the impact of faster switching times in the substitute (5ms operate/release versus 10ms/6ms)?

A: Faster switching times do not compromise compatibility with circuits designed for the original timing. Applications sensitive to switching speed may benefit from improved response characteristics.

Q: How does the contact material composition difference affect RF performance?

A: Both components feature gold-plated or gold-containing contact surfaces suitable for RF applications. The substitute's silver-gold composition maintains RF performance characteristics within the original specification envelope.

Q: Is the higher coil resistance of the substitute (257 Ohms versus 180 Ohms) a concern?

A: No. The higher resistance results in lower coil current draw while maintaining identical voltage thresholds. Existing 6VDC drive circuits will operate the substitute without modification.
