ADW1105W General Purpose Relay SPST 8A 5V

Part Overview

The ADW1105W is a general purpose relay manufactured by Panasonic Electric Works, designed for SPST-NO (1 Form A) switching applications with a 5VDC coil. This through-hole mounted relay is rated for 8A contact current and 250VAC maximum switching voltage, making it suitable for industrial control, automation, and general switching circuits. The part is currently active in production with 840 pieces in stock. Alternative models may be required due to inventory constraints, regional availability, or specific compliance certifications needed for particular applications.

Key Parameters

Substitute Part Grouping Explanation

The ADW1105W has one parametric equivalent: ADW1105TW. Substitution between these parts is valid based on the following criteria:

Both parts share identical electrical and mechanical specifications across all critical parameters: 5VDC coil voltage, SPST-NO contact form, 8A contact rating, 250VAC maximum switching voltage, 2000VA maximum load, through-hole mounting, 40mA coil current, 125 Ohms coil resistance, -40°C to 85°C operating temperature range, 15ms operate and release times, Silver Tin Oxide contact material, Class F coil insulation, and 4VDC must-operate voltage.

The key differentiators between ADW1105W and ADW1105TW are packaging designation (W vs. TW) and RoHS compliance level (RoHS Compliant vs. ROHS3 Compliant). Both parts maintain identical form, fit, and function for circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both ADW1105W and ADW1105TW are active production parts from Panasonic Electric Works with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and inventory availability.

The ADW1105W carries RoHS Compliant certification, suitable for applications requiring standard RoHS compliance. The ADW1105TW carries ROHS3 Compliant certification, appropriate for applications requiring enhanced RoHS3 compliance standards. Both parts maintain CQC, cURus, and VDE approvals.

The ADW1105TW currently has higher inventory availability (1252 pieces versus 840 pieces), which may influence selection for high-volume procurement. Both parts are sealed with flux protection and suitable for industrial control applications across the -40°C to 85°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ADW1105TW be used as a direct replacement for ADW1105W?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters including coil voltage, contact rating, switching voltage, operating temperature range, and timing specifications. The primary differences are RoHS compliance level and packaging designation.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant refers to the original Restriction of Hazardous Substances directive compliance. ROHS3 Compliant refers to the updated RoHS 3 directive with enhanced restrictions. Selection depends on your application's regulatory requirements.

Q: Are both parts suitable for 5VDC control circuits?

A: Yes. Both ADW1105W and ADW1105TW are rated for 5VDC coil voltage with a must-operate voltage of 4VDC, making them suitable for standard 5VDC control circuits.

Q: What is the maximum switching capacity of these relays?

A: Both relays are rated for 8A contact current at 250VAC maximum switching voltage, with a maximum load switching capacity of 2000VA.

Q: Are these relays suitable for high-temperature applications?

A: Both relays operate across the -40°C to 85°C temperature range with Class F coil insulation, suitable for industrial environments within these temperature limits.

Q: What is the coil power consumption?

A: Both relays draw 40mA at 5VDC, resulting in 200mW coil power consumption with a coil resistance of 125 Ohms.

Q: Do these relays require any special handling or storage?

A: Both parts have MSL (Moisture Sensitivity Level) 1, indicating unlimited shelf life without special moisture control requirements.
