JQ1-48V-F Equivalent & Substitute Parts

Part Overview

The JQ1-48V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 48VDC coil. This through-hole mounted relay is rated for 5A switching capacity and is designed for general industrial switching applications. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JQ1-48V-F is determined by the following critical parameters that must remain consistent:

• Coil Voltage: 48VDC (exact match required)
• Contact Form: SPDT (1 Form C) configuration
• Contact Rating: 5A minimum
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Coil Current: 8.3 mA (matching drive circuit requirements)
• Coil Resistance: 5.76 kOhms (ensuring compatibility with existing control circuits)

The ALQ148 meets these substitution criteria while offering enhanced operational characteristics within the allowed parameter range.

Parameter Comparison

Engineering Selection Recommendations

The ALQ148 is a direct functional substitute for the JQ1-48V-F. Both components are manufactured by Panasonic Electric Works and share identical critical electrical parameters including coil voltage, contact configuration, current rating, and coil resistance. The ALQ148 maintains active product status, ensuring continued availability and supply chain reliability compared to the obsolete JQ1-48V-F.

Both parts are RoHS compliant and carry equivalent regulatory standing. The ALQ148 provides an extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C), offering improved thermal performance in demanding environments. The ALQ148 holds additional international approvals (CQC, cURuus, VDE), providing enhanced certification coverage for applications requiring multi-regional compliance.

Frequently Asked Questions (FAQ)

Q: Can the ALQ148 directly replace the JQ1-48V-F in existing circuit boards?

A: Yes. Both relays share identical coil voltage (48VDC), contact configuration (SPDT), current rating (5A), coil resistance (5.76 kOhms), and PC pin termination. Through-hole mounting dimensions are compatible, allowing direct PCB substitution.

Q: What are the key differences between these two relays?

A: The ALQ148 offers an extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C) and includes additional international certifications (CQC, cURuus, VDE). The ALQ148 is an active product with current manufacturing support, whereas the JQ1-48V-F is obsolete.

Q: Are there any switching voltage limitations to consider?

A: The JQ1-48V-F supports 250VAC and 110VDC maximum switching voltage. The ALQ148 supports 250VAC and 30VDC maximum switching voltage. Applications requiring switching voltages above 30VDC should retain the JQ1-48V-F or identify alternative substitutes with higher voltage ratings.

Q: Does the ALQ148 require different drive circuit design?

A: No. The ALQ148 maintains identical coil current (8.3 mA), coil resistance (5.76 kOhms), and operating/release voltage thresholds (36 VDC must-operate, 2.4 VDC must-release). Existing drive circuits require no modification.

Q: What is the packaging difference between these parts?

A: The JQ1-48V-F is supplied without specified packaging designation. The ALQ148 is supplied in box packaging. Both are through-hole components suitable for manual or automated assembly.
