Substitution of the PCF-124D1M,000 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Requirements:

• Coil voltage: 24VDC
• Contact form: SPST-NO (1 Form A)
• Contact rating: 25 A minimum
• Switching voltage: 277VAC, 24VDC maximum
• Coil current: 37.5 mA
• Coil resistance: 640 Ohms
• Must operate voltage: 18 VDC minimum
• Must release voltage: 1.2 VDC maximum
• Operate and release times: 20 ms and 10 ms respectively
• Operating temperature range: -30°C ~ 55°C

Mechanical Compatibility Requirements:

• Mounting type: Through hole
• Termination style: PC pin, quick connect 0.250" (6.3mm)
• Base product series: PCF or OEG

Compliance Requirements:

• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

The PCF-124D2M,000 meets all electrical and mechanical parameters specified for the PCF-124D1M,000. The primary difference is the contact material composition and packaging configuration, which do not affect functional substitution within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

The PCF-124D2M,000 is a direct functional equivalent to the PCF-124D1M,000 based on matching electrical specifications, mechanical configuration, and operating characteristics. Both components are classified as obsolete products from the same manufacturer series.

Compliance Considerations:

The PCF-124D1M,000 carries RoHS Compliant certification, while the PCF-124D2M,000 carries ROHS3 Compliant certification. The PCF-124D2M,000 additionally carries REACH Unaffected status. These compliance upgrades in the substitute part reflect current regulatory standards and do not impact functional compatibility.

Contact Material Difference:

The PCF-124D1M,000 uses Silver Cadmium Oxide (AgCdO) contact material, while the PCF-124D2M,000 uses Silver Tin Oxide (AgSnO) contact material. Both materials are specified for the same electrical ratings and switching voltage parameters. This material difference reflects manufacturing evolution within the product line and does not affect substitution eligibility within the defined parameter set.

Packaging Configuration:

The PCF-124D2M,000 is available in bulk packaging, whereas the PCF-124D1M,000 uses standard packaging. Packaging configuration does not affect electrical or mechanical compatibility.
