JS1AF-B-6V General Purpose Relay Equivalent & Substitute Parts

Part Overview

The JS1AF-B-6V is a general purpose relay manufactured by Panasonic Electric Works, featuring a SPST-NO (1 Form A) contact configuration with a 6VDC coil. This through-hole mounted relay is rated for 10A switching capacity at 250VAC or 100VDC maximum. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JS1AF-B-6V is determined by strict equivalence across the following critical parameters:

• Coil voltage specification (6VDC)
• Contact configuration (SPST-NO / 1 Form A)
• Current rating (10A minimum)
• Switching voltage capability (250VAC, 100VDC)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Operating temperature range (-40°C ~ 85°C)
• Coil resistance (100 Ohms)
• Coil current draw (60 mA)

The JS1AF-B-6V-F qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while differing only in packaging configuration (Bulk versus standard packaging) and contact material composition.

Parameter Comparison

Engineering Selection Recommendations

The JS1AF-B-6V-F serves as a direct electrical and mechanical equivalent to the JS1AF-B-6V. Both parts are classified as obsolete products from Panasonic Electric Works within the JS series. The primary distinction between these parts is packaging format and RoHS compliance status of the substitute.

Selection between JS1AF-B-6V and JS1AF-B-6V-F should be based on:

• Packaging requirements (standard versus bulk)
• RoHS compliance mandates for the end application
• Contact material preference (Silver Alloy versus Silver Tin Oxide)
• Inventory availability and lead time considerations

Both parts maintain identical electrical performance characteristics, coil specifications, and thermal operating ranges, ensuring functional interchangeability in circuit applications requiring 6VDC SPST-NO relay functionality with 10A contact rating.

Frequently Asked Questions (FAQ)

Q: Can JS1AF-B-6V-F replace JS1AF-B-6V in existing designs?

A: Yes. The JS1AF-B-6V-F maintains identical electrical specifications, coil voltage, contact configuration, current rating, and switching voltage capability. The parts are functionally equivalent for circuit applications.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging configuration (Bulk for JS1AF-B-6V-F versus standard for JS1AF-B-6V), contact material composition (Silver Tin Oxide versus Silver Alloy), and RoHS compliance status (RoHS Compliant for JS1AF-B-6V-F).

Q: Are there any thermal or electrical performance differences?

A: No. Both parts operate across the identical temperature range (-40°C ~ 85°C), maintain the same coil resistance (100 Ohms), coil current (60 mA), and switching specifications (250VAC, 100VDC maximum).

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. If RoHS compliance is mandated, JS1AF-B-6V-F is the appropriate choice. For applications without RoHS requirements, either part provides equivalent functionality. Verify packaging and delivery requirements with your supplier.

Q: Are these parts still in production?

A: Both parts are classified as obsolete. Verify current availability with component distributors before finalizing procurement decisions.

Q: Does contact material affect relay performance?

A: Contact material composition (Silver Alloy versus Silver Tin Oxide) may influence contact wear characteristics and longevity under specific switching conditions. Both materials are suitable for the specified 10A, 250VAC/100VDC switching application.
