Key Parameters

Substitute Part Grouping Explanation

Substitution of the C93425 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

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

Acceptable Variation Parameters:

• Coil Current: Lower values acceptable (reduced power consumption)
• Operate Time: Faster operation acceptable
• Release Time: Faster release acceptable
• Operating Temperature Range: Narrower ranges acceptable if minimum -40°C and maximum 85°C are met
• Coil Resistance: Variation acceptable if coil voltage and current specifications are maintained
• Product Status: Active status preferred for obsolete components

The substitute part 1-1422025-0 satisfies all mandatory matching parameters and demonstrates improved electrical characteristics with reduced coil current and faster switching times, while maintaining full compatibility with the original C93425 electrical and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-1422025-0 is suitable for replacement of the obsolete C93425 based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical contact form (DPDT), current rating (2A), coil voltage (24VDC), and switching voltage specifications (250VAC, 220VDC - Max). The substitute demonstrates superior electrical efficiency with 65% reduction in coil current (5.8 mA versus 16.7 mA), resulting in lower power consumption and reduced thermal load on drive circuits.

Mechanical Compatibility: Both components feature identical through-hole mounting and PC pin termination, ensuring direct mechanical and electrical interface compatibility with existing printed circuit board designs without layout modifications.

Operational Performance: The substitute part exhibits faster operate time (4 ms versus 5 ms) and equivalent release time (4 ms versus 3 ms), providing comparable switching performance. The operating temperature range of -40°C to 85°C covers the majority of industrial and commercial applications, with the exception of extended low-temperature environments below -40°C.

Product Status and Compliance: The substitute part 1-1422025-0 carries active product status, ensuring long-term availability and supply chain continuity. Both components maintain RoHS3 compliance, supporting environmental and regulatory requirements.

Application Consideration: The substitute part requires a higher must-operate voltage (18 VDC versus 15.6 VDC). Design verification is necessary to confirm that drive circuit voltage margins accommodate this specification difference in applications with marginal supply voltage conditions.

Frequently Asked Questions (FAQ)

Q: Can the 1-1422025-0 be used as a direct replacement for the C93425 in existing designs?

A: Yes, the 1-1422025-0 provides direct electrical and mechanical compatibility with the C93425. Both components feature identical DPDT contact configuration, 2A current rating, 24VDC coil voltage, and through-hole PC pin termination. No circuit modifications or PCB layout changes are required for substitution.

Q: What is the primary difference between the C93425 and 1-1422025-0?

A: The primary differences are product status and coil characteristics. The C93425 is classified as obsolete, while the 1-1422025-0 is active. The substitute features reduced coil current (5.8 mA versus 16.7 mA) and higher coil resistance (4.114 kOhms versus 1.44 kOhms), resulting in improved power efficiency. The substitute also requires a higher must-operate voltage (18 VDC versus 15.6 VDC).

Q: Are there temperature range limitations when substituting the C93425 with 1-1422025-0?

A: The substitute part operates across -40°C to 85°C, compared to the original -55°C to 85°C. Applications requiring operation below -40°C must evaluate alternative solutions. The upper temperature limit of 85°C is identical for both components.

Q: Does the substitute part maintain the same contact material specifications?

A: Yes, both the C93425 and 1-1422025-0 feature Silver Nickel (AgNi) and Gold (Au) contact materials, ensuring equivalent contact reliability and electrical performance.

Q: What is the impact of the reduced coil current in the substitute part?

A: The 65% reduction in coil current (from 16.7 mA to 5.8 mA) reduces power consumption and heat generation in the relay coil. This results in lower drive circuit power requirements and reduced thermal stress on the relay and surrounding components. No negative impact on relay performance is introduced by this improvement.

Q: Is the substitute part available in the same packaging as the original?

A: The C93425 packaging is specified as dash (not detailed), while the 1-1422025-0 is supplied in tube packaging. Both components use identical through-hole PC pin termination and are compatible with standard PCB assembly processes.

Q: What design verification is required before implementing the substitute part?

A: Verification of drive circuit voltage margins is necessary to confirm that the higher must-operate voltage specification (18 VDC) of the substitute part is satisfied under all operating conditions. If the design operates with supply voltages below 18 VDC, alternative solutions must be evaluated.
