JQ1-B-9V-F Equivalent & Substitute Parts

Part Overview

The JQ1-B-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. 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

Substitution eligibility for the JQ1-B-9V-F is determined by strict alignment of the following critical parameters:

• Coil voltage must be 9VDC
• Contact configuration must be SPDT (1 Form C)
• Mounting type must be Through Hole
• Coil current must be 44.4 mA
• Must operate voltage must be 6.75 VDC
• Must release voltage must be 0.45 VDC
• Operating temperature range must encompass -40°C ~ 85°C
• Termination style must be PC Pin
• Coil insulation must be Class B

The ALQ109 meets all critical substitution criteria. While the ALQ109 is an active product with enhanced specifications in certain areas (higher contact rating capability and additional regulatory approvals), it maintains full electrical and mechanical compatibility with the JQ1-B-9V-F for standard 5A switching applications.

Parameter Comparison

Engineering Selection Recommendations

The ALQ109 is the qualified substitute for the obsolete JQ1-B-9V-F. Selection of the ALQ109 is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance exceeds the RoHS compliance of the original part, meeting current regulatory requirements
• Holds multiple regulatory approvals (CQC, cURuus, VDE) providing broader market acceptance
• Maintains identical coil voltage, contact configuration, mounting type, and coil current specifications
• Coil resistance variance of 0.5 Ohms is negligible and within acceptable engineering tolerance
• Contact material change from Silver Tin Oxide to Silver Nickel does not compromise switching performance at the specified 5A rating
• Release time increase from 10 ms to 20 ms remains within acceptable operational parameters for general purpose relay applications

Frequently Asked Questions (FAQ)

Q: Can the ALQ109 be used as a direct replacement for the JQ1-B-9V-F in existing designs?

A: Yes. The ALQ109 maintains identical coil voltage (9VDC), contact configuration (SPDT), mounting type (Through Hole), and coil current (44.4 mA) specifications. The part is pin-compatible and functionally equivalent for 5A switching applications.

Q: What is the significance of the contact material difference between the two parts?

A: The JQ1-B-9V-F uses Silver Tin Oxide (AgSnO) contacts while the ALQ109 uses Silver Nickel (AgNi) contacts. Both materials are suitable for the specified 5A switching rating and 250VAC maximum voltage. The contact material change does not affect compatibility for standard general purpose relay applications.

Q: Why does the ALQ109 have a lower maximum DC switching voltage (30VDC vs. 110VDC)?

A: The ALQ109 is rated for 250VAC, 30VDC maximum switching voltage, compared to the JQ1-B-9V-F specification of 250VAC, 110VDC. For applications requiring DC switching above 30VDC, the ALQ109 is not suitable. Verify your application's DC switching voltage requirement before selection.

Q: Is the release time difference between the two parts significant?

A: The ALQ109 has a release time of 20 ms compared to the JQ1-B-9V-F at 10 ms. This 10 ms difference is acceptable for general purpose relay applications. Applications with strict timing requirements below 20 ms release time should be evaluated individually.

Q: What regulatory approvals does the ALQ109 hold?

A: The ALQ109 holds CQC, cURuus, and VDE approvals, providing compliance for multiple international markets and applications requiring third-party certification.

Q: Are there any packaging differences between the two parts?

A: Both parts are supplied in box packaging. No packaging format changes are required for substitution.
