Key Parameters

Substitute Part Grouping Explanation

Substitution for the 9814-03-10 is determined by electrical and mechanical compatibility across the following critical parameters:

• Coil specification: Coil voltage (3.3VDC), coil current (47.1 mA), and coil resistance (70 Ohms) must match to ensure proper relay operation within the same control circuit.
• Contact performance: Contact form (SPST-NO), current rating (250 mA), and switching voltage capability (100VAC/100VDC) must remain consistent for load switching requirements.
• Mechanical form factor: Mounting type (Surface Mount) and termination style define PCB compatibility.
• Environmental compliance: RoHS, REACH, and temperature operating range ensure regulatory and functional continuity.

The identified substitute part 9814-03-00 maintains identical electrical specifications while offering an active product status and alternative packaging/termination configuration.

Parameter Comparison

Engineering Selection Recommendations

The 9814-03-00 is the direct electrical and functional equivalent for the obsolete 9814-03-10. Both parts share identical coil specifications, contact ratings, switching performance, and operating characteristics within the 9800 series.

Product Status: The 9814-03-00 holds active product status with established supply chains, making it the preferred selection for new designs and production continuity.

Regulatory Compliance: Both parts maintain RoHS and REACH compliance. The 9814-03-00 carries ROHS3 compliance designation, ensuring alignment with current regulatory frameworks.

Termination Consideration: The primary difference is termination style—the 9814-03-10 features axial termination while the 9814-03-00 uses gull wing termination. Both are surface mount configurations; design compatibility must be confirmed based on PCB layout and footprint requirements.

Frequently Asked Questions (FAQ)

Q: Can the 9814-03-00 directly replace the 9814-03-10 in an existing design? A: Electrical performance is identical across all switching and coil parameters. Compatibility depends on PCB footprint and termination style—axial versus gull wing terminations require different pad layouts.

Q: What is the significance of the termination style difference? A: Termination style affects PCB mounting and soldering configuration. Axial leads insert through holes or mount on pads; gull wing leads solder to surface pads. Board redesign may be necessary.

Q: Why is the 9814-03-10 obsolete while the 9814-03-00 remains active? A: Manufacturer product lifecycle decisions typically consolidate variants. The 9814-03-00 likely represents the manufacturer's standard configuration for the 9800 series.

Q: Are there any performance differences in contact switching speed? A: No. Both parts have identical operate time (0.25 ms) and release time (0.05 ms) specifications.

Q: How do RoHS Compliant and ROHS3 Compliant differ? A: ROHS3 refers to RoHS Directive 2011/65/EU as amended. Both designations confirm lead-free and hazardous substance restrictions; ROHS3 reflects the current regulatory version.

Q: What packaging is available for the 9814-03-00? A: The 9814-03-00 is supplied in tube packaging, distinct from the 9814-03-10 standard packaging configuration.
