ARE134HC90 Equivalent & Substitute Parts

Part Overview

The ARE134HC90 is a through-hole RF relay manufactured by Panasonic Electric Works, configured as a single-pole double-throw (SPDT) switch rated for 500 mA at 4.5 VDC. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement planning. The relay operates with a 200 mW coil power consumption and gold-plated contacts suitable for RF applications requiring reliable switching performance across the -40°C to 70°C operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ARE134HC90 is based on electrical and mechanical parameter equivalence within the Panasonic Electric Works relay portfolio. The primary substitute, ARS104H, maintains identical specifications across all critical switching parameters: coil voltage (4.5 VDC), coil current (44.4 mA), contact form (SPDT), contact rating (500 mA), switching voltage (30 VDC maximum), must-operate and must-release voltages, coil resistance (101 Ohms), contact material (gold plating), mounting type (through hole), and termination style (PC pin). Operating temperature range and coil power consumption remain consistent. The substitution is valid where these parameters define the functional requirements of the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The ARS104H is the direct functional equivalent for ARE134HC90 replacement applications. Both components are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: ARE134HC90 is obsolete while ARS104H is active production, ensuring long-term availability and supply chain continuity. Both components meet RoHS compliance requirements. The ARS104H exhibits a release time of 6 ms compared to 5 ms for the ARE134HC90; this 1 ms difference is within typical relay tolerance ranges and does not affect functional compatibility in standard switching applications. Selection of ARS104H is appropriate for new designs and obsolescence mitigation strategies.

Frequently Asked Questions (FAQ)

Q: What makes ARS104H a valid substitute for ARE134HC90? A: The ARS104H maintains identical coil voltage (4.5 VDC), coil current (44.4 mA), contact form (SPDT), contact rating (500 mA), switching voltage (30 VDC maximum), must-operate voltage (3.38 VDC), must-release voltage (0.45 VDC), coil resistance (101 Ohms), contact material (gold plating), mounting type (through hole), termination style (PC pin), and operating temperature range (-40°C to 70°C). These parameters define functional equivalence.

Q: Does the 1 ms difference in release time affect compatibility? A: The ARS104H release time is 6 ms versus 5 ms for ARE134HC90. This difference falls within standard relay manufacturing tolerances and does not compromise functional compatibility in typical switching applications where release time is not a critical timing parameter.

Q: Are both components RoHS compliant? A: Yes. ARE134HC90 is ROHS3 compliant and ARS104H is RoHS compliant. Both meet environmental compliance requirements.

Q: Why is product status important in this substitution? A: ARE134HC90 is classified as obsolete, meaning it is no longer in active production. ARS104H is active production status, ensuring availability for procurement and supporting long-term supply chain requirements.

Q: Can ARS104H be used in existing ARE134HC90 circuit designs without modification? A: Yes. Identical electrical and mechanical parameters permit direct substitution in existing through-hole PCB layouts without circuit design changes.
