Substitute Part Grouping Explanation

Substitution of the obsolete C93419 is based on electrical and mechanical parameter alignment within the relay component category. The primary substitute, TE Connectivity Potter & Brumfield Relays part number 1-1422025-0, maintains functional equivalence through the following critical parameters:

Matching Parameters:

• Coil Voltage: 24VDC (identical)
• Contact Form: DPDT (2 Form C) (identical)
• Contact Rating: 2 A (identical)
• Switching Voltage: 250VAC, 220VDC - Max (identical)
• Mounting Type: Through Hole (identical)
• Termination Style: PC Pin (identical)
• Contact Material: Silver Nickel (AgNi), Gold (Au) (identical)

The substitute part 1-1422025-0 is classified as active product status, ensuring long-term availability and supply chain continuity. Both components are manufactured by TE Connectivity Potter & Brumfield Relays and comply with ROHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Potter & Brumfield Relays 1-1422025-0 serves as the direct substitute for the obsolete C93419 based on electrical and mechanical parameter alignment. Both components maintain identical coil voltage, contact configuration, current rating, and switching voltage specifications required for DPDT relay applications.

The substitute part 1-1422025-0 is classified as active product status, providing assured long-term availability and supply chain support. Both components comply with ROHS3 and REACH regulatory requirements, ensuring environmental and compliance consistency.

Design considerations for substitution include the following parameter variations: the substitute part exhibits lower coil current (5.8 mA versus 8.3 mA) and higher coil resistance (4.114 kOhms versus 2.88 kOhms), resulting in reduced power consumption. The substitute requires a higher must-operate voltage of 18 VDC compared to 15.6 VDC for the original part. The operating temperature range of the substitute extends to -40°C minimum, compared to -55°C for the original component. These parameter differences must be evaluated against specific application requirements prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the 1-1422025-0 directly replace the C93419 in existing circuit designs?

A: The 1-1422025-0 maintains identical coil voltage (24VDC), contact form (DPDT), current rating (2A), and switching voltage specifications. However, the higher must-operate voltage requirement (18 VDC versus 15.6 VDC) and narrower low-temperature operating range (-40°C versus -55°C) must be evaluated against application-specific circuit parameters and environmental conditions.

Q: What are the key electrical differences between these two relay models?

A: The primary electrical differences are coil current (8.3 mA for C93419 versus 5.8 mA for 1-1422025-0), coil resistance (2.88 kOhms versus 4.114 kOhms), and must-operate voltage (15.6 VDC versus 18 VDC). The substitute part exhibits lower power consumption and faster operate time (4 ms versus 5 ms).

Q: Are the physical dimensions and mounting configurations identical?

A: Both components feature through-hole mounting with PC pin termination, ensuring mechanical compatibility in existing PCB layouts. No physical dimension data is provided in the component specifications.

Q: What is the difference between the telecom and general purpose relay classifications?

A: The C93419 is classified as a telecom relay, while the 1-1422025-0 is classified as a general purpose relay. Both components share identical electrical and mechanical specifications for DPDT switching applications. The classification difference reflects historical product line organization rather than functional capability differences.

Q: Are both components RoHS and REACH compliant?

A: Both the C93419 and 1-1422025-0 are ROHS3 compliant. The C93419 is REACH unaffected. Compliance documentation should be verified with the manufacturer for the substitute part.

Q: What is the inventory status for these components?

A: The C93419 (obsolete) has 2457 pieces in stock. The 1-1422025-0 (active) has 904 pieces in stock. Inventory levels are subject to change and should be confirmed with the component supplier.
