Key Parameters

Substitute Part Grouping Explanation

Substitution of the XT314012 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 12VDC
• Contact Form: SPDT (1 Form C)
• Contact Rating (Current): 16 A
• Mounting Type: Socketable
• Termination Style: Plug In
• Coil Type: Non Latching
• Relay Type: General Purpose

Acceptable Variation Parameters:

• Switching Voltage: Substitute must support minimum 400VAC
• Operating Temperature Range: Substitute must encompass or exceed the operating range
• Coil Current: Variation permitted within circuit design constraints
• Operate/Release Time: Variation permitted based on application timing requirements
• Contact Material: Variation permitted based on load characteristics
• Coil Resistance: Variation permitted based on supply circuit design

The substitute part 40.61.9.012.0000 from Finder Relays, Inc. meets all mandatory matching parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The XT314012 and 40.61.9.012.0000 are functionally equivalent general purpose relays suitable for direct substitution in socketable 12VDC SPDT switching applications rated for 16A at 400VAC maximum.

Compliance Alignment: Both parts maintain ROHS3 compliance and share identical ECCN (EAR99) and HTSUS (8536.41.0050) classifications, ensuring regulatory consistency in procurement and deployment.

Product Status Consideration: Both parts are classified as obsolete. Selection between these equivalents should be based on current inventory availability and supply chain reliability. The Finder 40.61.9.012.0000 currently maintains higher inventory levels (1307 pcs vs. 947 pcs).

Operational Envelope: The Finder substitute provides an extended operating temperature range (-40°C to 85°C versus -40°C to 70°C), offering broader environmental tolerance. The substitute's faster release time (3 ms versus 6 ms) and slightly faster operate time (7 ms versus 9 ms) are compatible with general purpose switching applications.

Electrical Characteristics: The substitute exhibits higher coil current (55 mA versus 33.3 mA) and lower coil resistance (220 Ohms versus 360 Ohms). These differences require verification that the supply circuit can accommodate the increased coil current draw without exceeding design specifications.

Certification Scope: The Finder part carries additional approval certifications (CCC, CSA, cURus, EAC, ENEC, RINA, VDE) and includes sealed flux protection, providing enhanced environmental protection compared to the TE Connectivity original.

Frequently Asked Questions (FAQ)

Q: Can the Finder 40.61.9.012.0000 directly replace the XT314012 in existing sockets?

A: Yes. Both relays feature identical socketable mounting and plug-in termination styles, enabling direct physical and electrical substitution in standard relay sockets designed for 12VDC SPDT configurations.

Q: What are the key differences between these two relays?

A: The primary differences are coil current (55 mA vs. 33.3 mA), coil resistance (220 Ohms vs. 360 Ohms), operating temperature range (-40°C to 85°C vs. -40°C to 70°C), contact material (AgCdO vs. AgNi), and response times (7/3 ms vs. 9/6 ms). All differences fall within acceptable variation parameters for general purpose relay applications.

Q: Does the higher coil current of the Finder relay affect circuit design?

A: The Finder substitute draws 55 mA compared to the original 33.3 mA. The supply circuit must be verified to confirm it can deliver this increased current without exceeding design limits or causing voltage regulation issues.

Q: Are both relays RoHS compliant?

A: Yes. Both the XT314012 and 40.61.9.012.0000 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What is the significance of the contact material difference?

A: The XT314012 uses Silver Nickel (AgNi) contacts while the Finder uses Silver Cadmium Oxide (AgCdO). Both materials are suitable for general purpose switching. AgCdO typically provides superior arc suppression and contact life under inductive loads, while AgNi offers lower contact resistance. Selection depends on specific load characteristics.

Q: Can I use the Finder relay in applications requiring the full -40°C to 70°C range?

A: Yes. The Finder relay's extended range (-40°C to 85°C) encompasses the original specification, ensuring compatibility across the entire original operating envelope and beyond.

Q: What packaging format is available for the Finder substitute?

A: The Finder 40.61.9.012.0000 is supplied in bulk packaging, whereas the original XT314012 packaging format is not specified in available documentation.
