Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARX1106 is determined by the following critical parameters:

• Coil voltage compatibility (6VDC nominal operation)
• Contact form (SPDT configuration required)
• Current rating capability (minimum 500 mA)
• Mounting type (through-hole preferred for direct PCB replacement)
• Termination style (PC pin for standard through-hole assembly)
• Operating temperature range (minimum -40°C ~ 70°C)
• Contact material (gold plating for signal integrity)

The DS1E-SL-DC6V qualifies as a direct substitute based on matching coil voltage, contact form, mounting type, termination style, and operating temperature range. The ARN12A4H operates at 4.5VDC and uses surface-mount termination, limiting its substitution applicability to designs where voltage and mounting modifications are acceptable.

Parameter Comparison

Engineering Selection Recommendations

DS1E-SL-DC6V is the primary substitute for ARX1106 applications. Both components share identical coil voltage (6VDC), contact form (SPDT), mounting type (through-hole), and termination style (PC pin). The DS1E-SL-DC6V is active in production and RoHS compliant, providing long-term availability and regulatory compliance. The higher current rating (2 A versus 500 mA) presents no compatibility issue for applications within the ARX1106 specification.

ARN12A4H is a secondary option limited to applications where design modifications are feasible. The 4.5VDC coil voltage requires circuit adjustment, and surface-mount termination necessitates PCB layout changes. The dual-coil latching mechanism differs from the ARX1106 single-coil design, requiring control logic modification.

Frequently Asked Questions (FAQ)

Q: Can DS1E-SL-DC6V directly replace ARX1106 in existing designs?

A: Yes. Both components operate at 6VDC, feature SPDT contact configuration, through-hole mounting, and PC pin termination. No circuit modifications are required for direct substitution.

Q: What is the primary limitation of ARN12A4H as a substitute?

A: The ARN12A4H operates at 4.5VDC, requiring power supply circuit modification. Additionally, gull-wing termination necessitates surface-mount PCB redesign, incompatible with through-hole ARX1106 layouts.

Q: Does the higher current rating of DS1E-SL-DC6V affect compatibility?

A: No. The 2 A rating of DS1E-SL-DC6V exceeds the 500 mA requirement of ARX1106. Applications operating within the original 500 mA specification remain fully compatible.

Q: Are there temperature range considerations for substitution?

A: DS1E-SL-DC6V maintains the -40°C ~ 70°C operating range of ARX1106. ARN12A4H extends to -40°C ~ 85°C, providing wider temperature capability if required by application.

Q: What compliance certifications apply to substitute parts?

A: DS1E-SL-DC6V carries RoHS compliance certification. Both substitute parts are classified under ECCN EAR99 and HTSUS 8536.41.0020, matching the regulatory classification of ARX1106.
