JS1-B-6V-F Equivalent & Substitute Parts

Part Overview

The JS1-B-6V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring SPDT (1 Form C) contact configuration with 6VDC coil voltage and 10A contact rating. This through-hole mounted relay operates at 250VAC and 100VDC maximum switching voltage with sealed construction and Class B coil insulation. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JS1-B-6V-F is determined by the following critical parameters:

• Coil Voltage: Must be 6VDC to ensure direct circuit compatibility without modification
• Contact Form: Must be SPDT (1 Form C) to maintain identical switching functionality
• Mounting Type: Must be Through Hole to ensure PCB compatibility
• Termination Style: Must be PC Pin for direct footprint compatibility
• Operating Temperature Range: Must support -40°C ~ 85°C minimum
• Coil Type: Must be Non Latching for equivalent operational behavior

The ALQ106 meets these core substitution criteria. However, differences exist in contact rating, switching voltage limits, and contact material that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The ALQ106 is an active product from the same manufacturer with identical coil voltage, contact form, mounting configuration, and termination style. This part is suitable as a substitute where application load requirements do not exceed 5A continuous current and 30VDC maximum switching voltage. The ALQ106 carries ROHS3 compliance and holds multiple approval certifications (CQC, cURuus, VDE), providing enhanced regulatory standing compared to the obsolete JS1-B-6V-F.

Applications requiring the full 10A contact rating or 100VDC switching capability of the original JS1-B-6V-F must evaluate alternative relay families, as the ALQ106 specifications do not support these higher performance parameters.

Frequently Asked Questions (FAQ)

Q: Can ALQ106 directly replace JS1-B-6V-F in existing designs?

A: Direct replacement is possible only if the application operates within ALQ106 specifications: maximum 5A continuous current and 30VDC switching voltage. Coil voltage, contact form, mounting type, and termination style are identical, ensuring PCB compatibility and circuit functionality within these limits.

Q: What are the key differences between these parts?

A: The primary differences are contact current rating (10A vs 5A), maximum switching voltage (100VDC vs 30VDC), switching speed (10ms vs 20ms), and contact material (AgSnO vs AgNi). The ALQ106 has higher coil current requirement (66.7mA vs 60mA) and lower must-release voltage (0.3VDC vs 0.6VDC).

Q: Are there packaging differences?

A: The JS1-B-6V-F uses standard packaging, while ALQ106 is supplied in box packaging. Both use PC Pin termination for through-hole mounting, ensuring identical footprint compatibility.

Q: What compliance certifications apply?

A: The JS1-B-6V-F is RoHS Compliant. The ALQ106 is ROHS3 Compliant and holds additional approvals from CQC, cURuus, and VDE, providing broader regulatory acceptance for new designs.

Q: Is the ALQ106 suitable for high-voltage DC switching applications?

A: No. The ALQ106 maximum DC switching voltage is 30VDC, compared to 100VDC for the JS1-B-6V-F. Applications requiring 100VDC switching capability require alternative relay selection.
