JQ1-9V-F Equivalent & Substitute Parts

Part Overview

The JQ1-9V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 9VDC coil. This through-hole mounted relay is designed for applications requiring 5A contact switching capability at 250VAC or 110VDC maximum switching voltage. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

The ALQ109 qualifies as a direct substitute for the JQ1-9V-F based on the following critical parameters:

Matching Parameters:

• Coil voltage: 9VDC (identical)
• Contact form: SPDT (1 Form C) (identical)
• Contact rating: 5 A (identical)
• Coil current: 44.4 mA (identical)
• Coil type: Non Latching (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pin (identical)
• Must operate voltage: 6.75 VDC (identical)
• Must release voltage: 0.45 VDC (identical)
• Coil resistance: 203 Ohms (functionally equivalent)

Differences:

• Switching voltage: ALQ109 rated 250VAC, 30VDC (vs. JQ1-9V-F: 250VAC, 110VDC)
• Operating temperature: ALQ109 -40°C ~ 85°C (vs. JQ1-9V-F: -40°C ~ 70°C)
• Release time: ALQ109 20 ms (vs. JQ1-9V-F: 10 ms)
• Contact material: ALQ109 Silver Nickel (vs. JQ1-9V-F: Silver Tin Oxide)
• Coil insulation: ALQ109 Class B (vs. JQ1-9V-F: Class E)
• Product status: ALQ109 Active (vs. JQ1-9V-F: Obsolete)

Parameter Comparison

Engineering Selection Recommendations

The ALQ109 is the qualified substitute for the obsolete JQ1-9V-F. Both components are manufactured by Panasonic Electric Works and share identical electrical characteristics for coil activation, contact switching, and timing parameters critical to relay function.

The ALQ109 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The component maintains RoHS compliance with ROHS3 certification, exceeding the original RoHS Compliant rating of the JQ1-9V-F. Additional certifications including CQC, cURuus, and VDE provide expanded regulatory acceptance.

Applications operating at DC voltages above 30VDC should evaluate the reduced maximum switching voltage specification of the ALQ109 (30VDC vs. 110VDC). The extended operating temperature range of the ALQ109 (-40°C ~ 85°C vs. -40°C ~ 70°C) provides improved thermal performance for high-temperature environments. The increased release time of 20 ms (vs. 10 ms) should be assessed for timing-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the ALQ109 directly replace the JQ1-9V-F in existing designs?

A: The ALQ109 is electrically compatible for coil activation and contact switching in applications operating within its specified maximum switching voltage of 250VAC or 30VDC. Applications requiring 110VDC switching capability require design evaluation.

Q: What is the primary difference between these relays?

A: The maximum DC switching voltage differs: JQ1-9V-F supports 110VDC while ALQ109 supports 30VDC maximum. Both relays share identical 9VDC coil voltage, 5A contact rating, and SPDT contact configuration.

Q: Are there packaging differences between JQ1-9V-F and ALQ109?

A: Yes. The JQ1-9V-F is supplied in Bulk packaging, while the ALQ109 is supplied in Box packaging. Both use identical PC Pin termination for through-hole mounting.

Q: Does the ALQ109 meet current compliance standards?

A: The ALQ109 is ROHS3 Compliant and holds certifications from CQC, cURuus, and VDE, providing compliance with current regulatory requirements. The obsolete JQ1-9V-F carries only RoHS Compliant status.

Q: How do the timing specifications compare?

A: Both relays share identical 20 ms operate time. The ALQ109 has a 20 ms release time compared to the JQ1-9V-F release time of 10 ms. Applications with strict release timing requirements should evaluate this difference.

Q: What contact materials are used in each relay?

A: The JQ1-9V-F uses Silver Tin Oxide (AgSnO) contact material, while the ALQ109 uses Silver Nickel (AgNi) contact material. Both materials are suitable for general purpose switching applications.
