ARE10A12Z Equivalent & Substitute Parts

Part Overview

The ARE10A12Z is a surface mount RF relay manufactured by Panasonic Electric Works, configured as a single pole double throw (SPDT) switch rated for 500 mA at 12 VDC. This component operates with a 16.7 mA coil current and 200 mW coil power, featuring gold-plated contacts and a non-latching coil design. The ARE10A12Z is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Active alternatives from the ARS series provide direct functional equivalence with improved product status and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARE10A12Z is determined by strict equivalence across the following critical parameters: coil voltage (12 VDC), contact form (SPDT), contact current rating (500 mA), switching voltage maximum (30 VDC), coil current (16.7 mA), coil power (200 mW), coil resistance (720 Ohms), mounting type (surface mount), termination style (gull wing), operating temperature range (-40°C to 70°C), contact material (gold plating), and coil type (non-latching). The ARS14A12Z and ARS14Y12 meet all these electrical and mechanical requirements. Differences in packaging format (tape & reel versus tube) and release time (6 ms versus 5 ms) do not affect functional substitution. Both substitute parts are manufactured by Panasonic Electric Works and maintain active product status with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both ARS14A12Z and ARS14Y12 are direct functional equivalents to the obsolete ARE10A12Z. Selection between these two substitute parts should be based on packaging requirements and supply chain considerations. The ARS14A12Z is supplied in tape & reel format, suitable for automated assembly processes. The ARS14Y12 is supplied in tube packaging, appropriate for manual assembly or lower-volume applications. Both parts maintain active product status with Panasonic Electric Works, ensuring long-term availability and supply chain stability. The ARS14Y12 carries ROHS3 compliance with REACH unaffected status, providing enhanced regulatory alignment for applications requiring the latest environmental standards. The marginal difference in release time (6 ms versus 5 ms for the original) falls within acceptable tolerances for typical relay switching applications and does not compromise functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can ARS14A12Z and ARS14Y12 be used interchangeably with ARE10A12Z? A: Yes. Both parts meet all electrical and mechanical specifications required for direct substitution. The primary difference is packaging format: ARS14A12Z uses tape & reel, while ARS14Y12 uses tube packaging. Selection depends on assembly process requirements.

Q: What is the significance of the 1 ms difference in release time between the original and substitute parts? A: The ARE10A12Z has a 5 ms release time, while both ARS substitutes have 6 ms release time. This 1 ms difference is negligible for standard relay switching applications and does not affect functional compatibility or circuit performance.

Q: Why is the ARE10A12Z classified as obsolete? A: The ARE10A12Z is an older product from the ARE series. Panasonic Electric Works has transitioned to the ARS series, which offers the same electrical performance with improved product status and ongoing manufacturing support.

Q: Are there compliance differences between ARS14A12Z and ARS14Y12? A: Both parts are RoHS compliant. The ARS14Y12 carries ROHS3 compliance with REACH unaffected status, providing enhanced regulatory documentation for applications requiring the latest environmental standards. The ARS14A12Z maintains standard RoHS compliance.

Q: Which substitute part should be selected for high-volume automated assembly? A: The ARS14A12Z in tape & reel packaging is optimized for automated pick-and-place assembly processes and high-volume production environments.

Q: Which substitute part should be selected for manual assembly or lower-volume applications? A: The ARS14Y12 in tube packaging is suitable for manual assembly, prototyping, and lower-volume production runs.

Q: Are the coil specifications identical across all three parts? A: Yes. All three parts share identical coil voltage (12 VDC), coil current (16.7 mA), coil power (200 mW), and coil resistance (720 Ohms). Electrical drive requirements remain unchanged when substituting.

Q: Do the substitute parts maintain the same contact rating and switching characteristics? A: Yes. Contact form (SPDT), contact current rating (500 mA), switching voltage maximum (30 VDC), must operate voltage (9 VDC), must release voltage (1.2 VDC), and operate time (10 ms) are identical across all three parts.
