JQ1APF-F-5V-F Equivalent & Substitute Parts

Part Overview

The JQ1APF-F-5V-F is a general purpose relay manufactured by Panasonic Electric Works, configured as a SPST-NO (1 Form A) with a 5VDC coil and 10A contact rating. This through-hole mounted relay is designed for general switching applications with a maximum switching voltage of 250VAC or 110VDC. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, repairs, and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JQ1APF-F-5V-F is determined by the following critical parameters:

• Coil Voltage: 5VDC (exact match required for direct circuit compatibility)
• Contact Form: SPST-NO (1 Form A) (switching topology must remain identical)
• Mounting Type: Through Hole (PCB layout compatibility)
• Termination Style: PC Pin (connection method must match)
• Coil Insulation Class: Class F (thermal and electrical safety rating)

Substitute parts are classified into two categories:

Direct Substitutes meet all critical parameters and provide equivalent functionality with active product status and modern compliance certifications.

Similar Substitutes match core electrical parameters but may differ in secondary specifications such as contact material or coil insulation class, requiring engineering evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

ALQ3F05 is the primary direct substitute for JQ1APF-F-5V-F. It maintains identical coil voltage (5VDC), coil current (40 mA), coil resistance (125 Ohms), and coil insulation class (Class F). The part is active in production with ROHS3 compliance and modern certifications (CQC, cURuus, VDE). The contact rating is reduced from 10A to 5A, and maximum DC switching voltage is reduced from 110VDC to 30VDC. These reductions require application-level verification to confirm compatibility with existing load requirements.

ALQ305 provides an alternative 5VDC substitute with identical electrical drive characteristics (40 mA coil current, 125 Ohms resistance) and active product status. The coil insulation class is Class B rather than Class F, representing a lower thermal rating. Contact rating and switching voltage specifications match ALQ3F05. This part is suitable for applications where Class B insulation is acceptable.

ALQ312 is not recommended as a direct substitute. Although it shares the same manufacturer, series, and through-hole mounting, the 12VDC coil voltage requires circuit redesign and is incompatible with 5VDC drive circuits. This part is listed only for reference in cases where system voltage can be modified.

Frequently Asked Questions (FAQ)

Q: Can ALQ3F05 replace JQ1APF-F-5V-F in all applications?

A: ALQ3F05 is electrically compatible for coil drive circuits. However, the contact rating is reduced from 10A to 5A, and maximum DC switching voltage is reduced from 110VDC to 30VDC. Applications must be evaluated to confirm that load current and switching voltage remain within ALQ3F05 specifications.

Q: What is the difference between ALQ3F05 and ALQ305?

A: Both parts have identical 5VDC coil voltage, 40 mA coil current, and 125 Ohms coil resistance. The primary difference is coil insulation class: ALQ3F05 uses Class F (higher thermal rating), while ALQ305 uses Class B (lower thermal rating). Selection depends on application thermal requirements.

Q: Why is the contact rating lower on substitute parts?

A: The substitute parts ALQ3F05 and ALQ305 are rated for 5A maximum contact current, compared to the original 10A rating. This is a design difference between the JQ and ALQ series. Applications requiring 10A switching must either use the original JQ1APF-F-5V-F or identify alternative relay series with higher current ratings.

Q: Are the substitute parts RoHS compliant?

A: Yes. ALQ3F05, ALQ305, and ALQ312 are all ROHS3 compliant. The original JQ1APF-F-5V-F does not specify RoHS status.

Q: Can I use ALQ312 as a substitute?

A: ALQ312 operates on 12VDC, not 5VDC. It cannot be used as a direct substitute without modifying the control circuit to supply 12VDC instead of 5VDC. This part is suitable only for new designs or systems where voltage modification is feasible.

Q: What certifications do the substitute parts carry?

A: ALQ3F05, ALQ305, and ALQ312 all carry CQC, cURuus, and VDE certifications, providing international compliance for industrial and consumer applications.
