Engineering Selection Recommendations

The G5Q-1 DC5 relay from Omron Electronics Inc-EMC Div is a qualified substitute for the PCH-105D2,000. Selection of this substitute is supported by the following factors:

Compliance and Certification: Both relays maintain ROHS3 compliance, ensuring regulatory alignment for applications subject to hazardous substance restrictions. The G5Q-1 DC5 carries REACH Unaffected status, providing additional environmental compliance documentation.

Product Availability: The PCH-105D2,000 carries Last Time Buy status, indicating end-of-life production. The G5Q-1 DC5 maintains Active product status with current manufacturing availability, ensuring supply chain continuity.

Electrical Performance: The G5Q-1 DC5 provides identical coil voltage, contact form, coil current, and coil resistance specifications. The substitute's 10A contact rating exceeds the original 5A requirement, and its -40°C ~ 105°C operating temperature range extends beyond the original -40°C ~ 85°C specification, providing enhanced performance margins.

Mechanical Compatibility: Both relays share identical through-hole mounting type and PC pin termination style, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the G5Q-1 DC5 be used as a direct replacement for the PCH-105D2,000 in existing designs?

A: Yes. The G5Q-1 DC5 matches all mandatory electrical and mechanical parameters including coil voltage, contact form, mounting type, and termination style. The substitute's higher current rating and extended temperature range do not create compatibility issues in applications designed for the original 5A, 5VDC specification.

Q: What is the difference in contact current rating between these relays?

A: The PCH-105D2,000 is rated for 5A continuous contact current, while the G5Q-1 DC5 is rated for 10A. The higher rating of the substitute provides additional current-carrying capacity without affecting circuit operation at the original 5A design point.

Q: Are there packaging differences between these relays?

A: Yes. The PCH-105D2,000 is supplied in Bulk packaging, while the G5Q-1 DC5 is supplied in Tray packaging. Both are through-hole mounted components with PC pin termination. Packaging format does not affect electrical or mechanical compatibility.

Q: What is the operating temperature difference?

A: The PCH-105D2,000 operates from -40°C to 85°C, while the G5Q-1 DC5 operates from -40°C to 105°C. The substitute's extended upper temperature limit of 105°C provides additional thermal margin for applications operating at elevated ambient temperatures.

Q: Do both relays have identical coil specifications?

A: Yes. Both relays feature 5VDC coil voltage, 80 mA coil current, 63 Ohms coil resistance, and non-latching coil type. Coil drive circuits designed for the PCH-105D2,000 operate identically with the G5Q-1 DC5.

Q: Are there any compliance or certification differences?

A: Both relays are ROHS3 compliant. The G5Q-1 DC5 carries additional REACH Unaffected status. The PCH-105D2,000 lists REACH status as Vendor Undefined. Both relays carry EAR99 ECCN classification.
