JQ1AP-24V Equivalent & Substitute Parts

Part Overview

The JQ1AP-24V is a general purpose relay manufactured by Panasonic Electric Works, featuring SPST-NO (1 Form A) contact configuration with 24VDC coil voltage and 10A contact rating. This through-hole mounted relay operates at 250VAC and 110VDC maximum switching voltage with Class E coil insulation. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JQ1AP-24V is determined by the following critical parameters:

Primary Matching Criteria:

• Coil voltage: 24VDC (exact match required for direct circuit compatibility)
• Contact form: SPST-NO (1 Form A) (functional switching configuration)
• Mounting type: Through Hole (physical board compatibility)
• Termination style: PC Pin (connection compatibility)

Secondary Compatibility Factors:

• Contact rating current: Minimum 10A (load capacity requirement)
• Switching voltage: Minimum 250VAC capability (application voltage support)
• Coil current: 8.3 mA (drive circuit compatibility)
• Coil resistance: 2.88 kOhms (circuit impedance matching)

The ALQ3F24 meets primary criteria with matching 24VDC coil voltage, SPST-NO contact form, through-hole mounting, and PC pin termination. However, its 5A contact rating falls below the 10A requirement of the original part, limiting it to lower-current applications. The ALQ3F12 operates at 12VDC and is unsuitable for 24VDC circuits. The PCH-124L2MH,000 from TE Connectivity matches the 24VDC coil voltage, SPST-NO configuration, and through-hole mounting with 5A contact rating, but represents a different manufacturer platform.

Parameter Comparison

Engineering Selection Recommendations

ALQ3F24 (Panasonic Electric Works): This part maintains the same manufacturer platform as the original JQ1AP-24V with identical coil voltage (24VDC), contact form (SPST-NO), mounting type (through-hole), and coil parameters (8.3 mA, 2.88 kOhms). The part is currently active with ROHS3 compliance and extended operating temperature range (-40°C to 85°C). Primary limitation is the 5A contact rating versus the original 10A specification. Selection is appropriate for applications where load current does not exceed 5A and where Panasonic platform continuity is required.

PCH-124L2MH,000 (TE Connectivity Potter & Brumfield): This part provides 24VDC coil voltage, SPST-NO contact configuration, and through-hole mounting with matching coil current (8.3 mA) and coil resistance (2.88 kOhms). The part carries ROHS3 compliance and extended operating temperature range. Contact rating is 5A, matching the ALQ3F24 limitation. The part is designated Last Time Buy status, indicating limited future availability. Selection introduces a different manufacturer platform and should be evaluated for mechanical fit and circuit board layout compatibility.

ALQ3F12 (Not Recommended): This part operates at 12VDC coil voltage and is incompatible with 24VDC circuits. It is listed for reference only as a similar product within the ALQ series.

Frequently Asked Questions (FAQ)

Q: Can ALQ3F24 directly replace JQ1AP-24V in all applications?

A: ALQ3F24 provides electrical compatibility for coil drive circuits due to matching 24VDC voltage, 8.3 mA coil current, and 2.88 kOhms coil resistance. However, the 5A contact rating is half the original 10A specification. Direct replacement is suitable only for applications where the actual load current does not exceed 5A. Applications requiring the full 10A switching capacity require alternative solutions or circuit redesign.

Q: What are the timing differences between JQ1AP-24V and substitute parts?

A: JQ1AP-24V operates with 5 ms operate time and 2 ms release time. ALQ3F24 operates with 20 ms operate time and 20 ms release time. PCH-124L2MH,000 operates with 10 ms operate time and 5 ms release time. Applications with timing-critical switching requirements must account for these differences in system design.

Q: Are there voltage compatibility concerns with the substitute parts?

A: JQ1AP-24V supports 250VAC and 110VDC maximum switching voltage. ALQ3F24 supports 250VAC and 30VDC maximum switching voltage. PCH-124L2MH,000 supports 277VAC and 30VDC maximum switching voltage. Applications switching voltages above 30VDC DC require the original JQ1AP-24V or equivalent parts with higher DC voltage ratings.

Q: What is the impact of Last Time Buy status for PCH-124L2MH,000?

A: Last Time Buy designation indicates the manufacturer has announced end-of-life for this part. Existing inventory may be available, but future procurement will not be possible. Long-term designs should prioritize ALQ3F24 or identify alternative solutions with active product status.

Q: How do operating temperature ranges affect part selection?

A: JQ1AP-24V operates from -40°C to 70°C. Both ALQ3F24 and PCH-124L2MH,000 operate from -40°C to 85°C, providing extended high-temperature capability. Applications operating above 70°C benefit from the extended range of substitute parts.

Q: Are there packaging or inventory considerations?

A: JQ1AP-24V is available in 771 pieces. ALQ3F24 is available in 827 pieces (Box packaging). PCH-124L2MH,000 is available in 4902 pieces (Bulk packaging). Packaging format may affect handling, storage, and integration into manufacturing processes.
