Engineering Selection Recommendations

PCFN-124D2M000 (TE Connectivity)

This part is a parametric equivalent to the PCFN-124D2M,000 with identical electrical and mechanical specifications. It is manufactured by the same supplier (TE Connectivity) and maintains the same coil voltage, contact rating, switching voltage, and timing characteristics. The PCFN-124D2M000 is classified as active product status, ensuring ongoing availability and supply chain support.

The PCFN-124D2M000 differs in RoHS compliance status (non-compliant versus ROHS3 compliant) and REACH documentation availability. These compliance differences must be evaluated against application requirements and regulatory obligations.

ALF1P24 (Panasonic Electric Works)

This part is a functional substitute with equivalent electrical and mechanical compatibility. It maintains the same 24VDC coil voltage, 37.5 mA coil current, 640 Ohms coil resistance, and non-latching operation. The ALF1P24 features identical mounting type (through hole) and termination style (PC pin).

The ALF1P24 differs in contact rating (20 A versus 25 A), maximum switching voltage (250VAC versus 277VAC), and release time (15 ms versus 10 ms). These differences indicate reduced current-carrying capacity and switching voltage capability. The ALF1P24 is classified as active product status with ROHS3 compliance and REACH unaffected status.

Selection between PCFN-124D2M000 and ALF1P24 depends on application current requirements and switching voltage specifications. For applications requiring the full 25 A rating or 277VAC switching capability, PCFN-124D2M000 is the appropriate selection. For applications with maximum current requirements of 20 A and switching voltages not exceeding 250VAC, ALF1P24 is suitable.

Frequently Asked Questions (FAQ)

Q: Can the ALF1P24 be used as a direct replacement for the PCFN-124D2M,000?

A: The ALF1P24 is a functional substitute for applications with current requirements of 20 A or less and switching voltages not exceeding 250VAC. For applications requiring the full 25 A contact rating or 277VAC switching capability, the ALF1P24 does not meet the electrical specifications and is not suitable.

Q: What is the difference between PCFN-124D2M,000 and PCFN-124D2M000?

A: These parts are parametrically equivalent with identical electrical and mechanical specifications. The primary differences are product status (obsolete versus active), packaging format (not specified versus tube), and compliance documentation (ROHS3 compliant and REACH unaffected versus RoHS non-compliant and REACH information available upon request). PCFN-124D2M000 is the active equivalent suitable for new designs and ongoing production.

Q: Are all substitute parts compatible with the same PCB footprint?

A: All three parts feature through-hole mounting with PC pin termination. Physical footprint compatibility depends on specific pin spacing and mounting hole dimensions, which are not provided in the available technical parameters. Mechanical drawings must be consulted to confirm PCB layout compatibility.

Q: What is the coil current requirement for all substitute parts?

A: All parts, including the main part PCFN-124D2M,000, PCFN-124D2M000, and ALF1P24, require 37.5 mA coil current with 640 Ohms coil resistance at 24VDC. This ensures identical drive circuit requirements across all substitutes.

Q: How do the operating temperature ranges compare?

A: The PCFN-124D2M,000 and PCFN-124D2M000 operate from -30°C to 55°C. The ALF1P24 operates from -40°C to 60°C, providing a wider temperature range. Application temperature requirements determine whether the extended range of the ALF1P24 is beneficial.

Q: What compliance certifications apply to each part?

A: PCFN-124D2M,000 is ROHS3 compliant, REACH unaffected, and carries EAR99 ECCN classification. PCFN-124D2M000 is RoHS non-compliant with REACH information available upon request. ALF1P24 is ROHS3 compliant, REACH unaffected, and carries cURus and VDE approval agency certifications. Regulatory requirements for the target application determine which compliance profile is appropriate.
