Parameter Comparison

Engineering Selection Recommendations

The G5Q-1 DC24 relay is a qualified substitute for the PCH-124D2,000 based on the following engineering criteria:

Functional Compatibility: Both relays share identical coil voltage, contact form, coil current, and coil resistance specifications. The switching voltage and seal rating are equivalent, ensuring compatible circuit operation.

Contact Rating Advantage: The G5Q-1 DC24 provides a 10A contact rating compared to the 5A rating of the PCH-124D2,000. This higher rating accommodates applications with increased current demands while maintaining backward compatibility with existing 5A circuit designs.

Product Status: The G5Q-1 DC24 maintains Active product status, providing assured long-term availability and supply chain stability. The PCH-124D2,000 Last Time Buy status necessitates transition planning.

Compliance Certifications: Both relays are REACH Unaffected and carry EAR99 ECCN classification. The G5Q-1 DC24 meets ROHS3 compliance, exceeding the RoHS Compliant status of the PCH-124D2,000.

Operating Temperature: The G5Q-1 DC24 extends the upper operating temperature limit to 105°C, providing enhanced thermal performance for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the G5Q-1 DC24 directly replace the PCH-124D2,000 in existing circuit designs?

A: Yes. Both relays share identical coil voltage (24VDC), contact form (SPDT), coil current (16.7 mA), coil resistance (1.44 kOhms), and switching voltage specifications. The through-hole PC pin termination style is identical, enabling direct board-level substitution.

Q: What is the significance of the higher 10A contact rating on the G5Q-1 DC24?

A: The G5Q-1 DC24 contact rating of 10A exceeds the PCH-124D2,000 rating of 5A. This provides additional current-carrying capacity for the same switching function. Applications designed for 5A operation remain fully compatible, as the substitute part accommodates the original current requirement with margin.

Q: Are there differences in contact material between these relays?

A: The PCH-124D2,000 uses Silver Tin Oxide (AgSnO) contact material, while the G5Q-1 DC24 uses Silver Alloy. Both materials are suitable for general purpose relay applications with equivalent switching voltage ratings (277VAC, 30VDC - Max).

Q: How do the operating temperature ranges compare?

A: The PCH-124D2,000 operates from -40°C to 85°C. The G5Q-1 DC24 extends the upper limit to 105°C, providing 20°C additional thermal headroom for high-temperature applications.

Q: What is the inventory status of these parts?

A: The PCH-124D2,000 has 1031 pieces in stock with Last Time Buy status. The G5Q-1 DC24 has 14702 pieces in stock with Active product status, ensuring sustained availability.

Q: Are both relays RoHS compliant?

A: Yes. The PCH-124D2,000 is RoHS Compliant. The G5Q-1 DC24 meets the more recent ROHS3 Compliant standard, providing enhanced environmental compliance.

Q: Do these relays have identical packaging?

A: Both relays are supplied in Tray packaging, maintaining consistent handling and storage requirements.
