JWD-172-155 Equivalent & Substitute Parts

Part Overview

The JWD-172-155 is an active-status reed relay manufactured by TE Connectivity Potter & Brumfield Relays. This through-hole mounted component operates at 5VDC with a single-pole double-throw (SPDT) contact configuration and a maximum contact rating of 500 mA. The relay is designed for applications requiring low-power switching with fast response times and operates across an industrial temperature range of -35°C to 85°C. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require component alternatives that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JWD-172-155 are qualified based on the following critical parameters that determine functional compatibility:

Matching Parameters (Required for Substitution):

• Coil Voltage: 5VDC
• Contact Form: SPDT (1 Form C)
• Coil Current: 25 mA
• Coil Type: Non Latching
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Must Operate Voltage: 3.8 VDC
• Must Release Voltage: 0.5 VDC
• Coil Resistance: 200 Ohms
• RoHS Status: ROHS3 Compliant

Variable Parameters (Allowed Variance):

• Contact Rating (Current): The JWD-172-155 specifies 500 mA maximum. Substitute parts with lower contact ratings may be used in applications where the actual switching current does not exceed the substitute part's rating.
• Operating Temperature Range: The JWD-172-155 operates from -35°C to 85°C. Substitute parts with narrower temperature ranges are acceptable if the application operates within the substitute part's specified range.
• Switching Voltage: Substitute parts may have different maximum switching voltage ratings provided the application voltage does not exceed the substitute part's specification.
• Response Times (Operate/Release): Variations in operate and release times are acceptable provided the application timing requirements are met by the substitute part.

The substitute part 8L41-05-001 from Coto Technology meets all matching parameters and is therefore qualified as a functional equivalent for the JWD-172-155.

Parameter Comparison

Engineering Selection Recommendations

Both the JWD-172-155 and 8L41-05-001 are active-status products with ROHS3 compliance and REACH unaffected status, making them suitable for current procurement and long-term supply chain planning.

Selection Criteria:

The JWD-172-155 is the primary choice when the application requires a 500 mA contact rating and operation across the full temperature range of -35°C to 85°C.

The 8L41-05-001 is a qualified substitute when:

• The application switching current does not exceed 250 mA
• The operating environment remains within -20°C to 85°C
• Faster response times (1 ms operate and release versus 1.5 ms and 3 ms) are beneficial to the application
• Higher switching voltage capability (100VAC/100VDC versus 28VDC) is required

Both parts share identical coil voltage, coil current, coil resistance, and voltage threshold specifications, ensuring equivalent control circuit compatibility. The primary differentiation lies in contact current capacity and temperature range, which must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 8L41-05-001 be used as a direct replacement for the JWD-172-155 in all applications?

A: The 8L41-05-001 is functionally compatible with the JWD-172-155 for applications where the switching current does not exceed 250 mA and the operating temperature remains between -20°C and 85°C. Applications requiring the full 500 mA contact rating or operation below -20°C require the JWD-172-155.

Q: Are the control circuit connections identical between these two relays?

A: Yes. Both relays share identical coil voltage (5VDC), coil current (25 mA), coil resistance (200 Ohms), must-operate voltage (3.8 VDC), and must-release voltage (0.5 VDC). Control circuit connections are therefore identical.

Q: What is the difference in switching voltage capability between these parts?

A: The JWD-172-155 supports a maximum switching voltage of 28VDC. The 8L41-05-001 supports 100VAC and 100VDC maximum switching voltages. The substitute part provides higher voltage switching capability.

Q: How do the response times differ between these relays?

A: The JWD-172-155 has an operate time of 1.5 ms and release time of 3 ms. The 8L41-05-001 has an operate time of 1 ms and release time of 1 ms. The substitute part responds faster.

Q: Are both parts available in the same packaging format?

A: Yes. Both the JWD-172-155 and 8L41-05-001 are supplied in tube packaging with through-hole PC pin termination, ensuring identical mechanical compatibility with printed circuit board layouts.

Q: What is the temperature range limitation of the 8L41-05-001 compared to the JWD-172-155?

A: The JWD-172-155 operates from -35°C to 85°C, while the 8L41-05-001 operates from -20°C to 85°C. The substitute part has a 15°C higher minimum operating temperature. Applications requiring operation below -20°C must use the JWD-172-155.

Q: Are both relays RoHS compliant?

A: Yes. Both the JWD-172-155 and 8L41-05-001 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
