ARE13A4HZ Equivalent & Substitute Parts

Part Overview

The ARE13A4HZ is a surface mount RF relay manufactured by Panasonic Electric Works, configured as a single pole double throw (SPDT) switch with 500 mA contact rating and 4.5 VDC coil voltage. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The relay operates with non-latching coil characteristics and gold-plated contacts suitable for RF applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARE13A4HZ is determined by strict equivalence across the following critical parameters:

• Coil voltage: 4.5 VDC
• Coil current: 44.4 mA
• Contact form: SPDT (1 Form C)
• Contact rating: 500 mA
• Switching voltage: 30 VDC maximum
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Operating temperature range: -40°C ~ 70°C
• Contact material: Gold Plating
• Coil power: 200 mW
• Coil resistance: 101 Ohms (±0.3 Ohm tolerance acceptable)

The identified substitute parts ARS10A4HZ and ARS10Y4H meet all critical electrical and mechanical parameters. Both are manufactured by Panasonic Electric Works and maintain active product status, providing long-term availability advantages over the obsolete ARE13A4HZ.

Parameter Comparison

Engineering Selection Recommendations

Both ARS10A4HZ and ARS10Y4H are direct functional equivalents to the obsolete ARE13A4HZ. Selection between these two active alternatives should be based on packaging and procurement requirements:

ARS10A4HZ is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes and high-volume production environments.

ARS10Y4H is supplied in Tube packaging, appropriate for manual assembly, lower-volume applications, or inventory management where individual component access is preferred.

Both parts maintain RoHS compliance and are manufactured by the same supplier, ensuring consistent quality and long-term availability. The minor difference in release time (6 ms versus 5 ms for the original part) and coil resistance (101.3 Ohms versus 101 Ohms) fall within acceptable engineering tolerances for RF relay applications and do not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can ARS10A4HZ and ARS10Y4H be used interchangeably with ARE13A4HZ?

A: Yes. Both substitute parts meet all critical electrical and mechanical specifications. The differences in release time (1 ms longer) and coil resistance (0.3 Ohm variance) are within acceptable tolerances for this relay category and do not impact circuit performance.

Q: What is the primary reason for substitution?

A: The ARE13A4HZ is classified as obsolete. The ARS10A4HZ and ARS10Y4H are active products from the same manufacturer, ensuring continued availability and supply chain stability.

Q: How do packaging options differ between the substitutes?

A: ARS10A4HZ is supplied in Tape & Reel format for automated pick-and-place assembly. ARS10Y4H is supplied in Tube format for manual handling and component-level inventory management. Electrical and mechanical performance are identical.

Q: Are there any compliance differences?

A: No. All three parts are RoHS compliant. The substitute parts maintain the same regulatory certifications as the original ARE13A4HZ.

Q: What is the inventory status of each part?

A: ARE13A4HZ has 911 pieces in stock (obsolete status). ARS10A4HZ has 770 pieces available. ARS10Y4H has 1,561 pieces available, offering the highest stock level among the three options.
