Key Parameters

Substitute Part Grouping Explanation

The K10P-11A15-48 from TE Connectivity Potter & Brumfield Relays qualifies as a substitute for the LY2 AC48 based on the following critical parameters:

• Coil Voltage: Both operate at 48VAC
• Contact Form: Both feature DPDT (2 Form C) configuration
• Mounting Type: Both are socketable with plug-in termination
• Coil Type: Both are non-latching relays
• Product Status: Both are active production parts
• RoHS Compliance: Both meet RoHS requirements

The K10P-11A15-48 provides a higher contact current rating (15A versus 10A), which represents an upgrade capability. The substitute maintains compatibility with the same coil voltage and contact configuration while offering enhanced current handling capacity for applications requiring additional margin.

Parameter Comparison

Engineering Selection Recommendations

Both the LY2 AC48 and K10P-11A15-48 are active production relays with current RoHS compliance certifications. The LY2 AC48 maintains the original design specification with a 10A contact rating and operates within the -25°C to 55°C temperature range. The K10P-11A15-48 provides an alternative with increased contact current capacity (15A), faster switching response times (13ms operate, 10ms release versus 25ms each), and an extended operating temperature range (-45°C to 70°C). Both relays are socketable with plug-in termination and maintain the required DPDT contact configuration for 48VAC coil applications. Selection between these parts depends on application-specific requirements for current capacity, switching speed, and temperature environment.

Frequently Asked Questions (FAQ)

Q: Can the K10P-11A15-48 directly replace the LY2 AC48 in existing applications?

A: The K10P-11A15-48 is mechanically and electrically compatible as a substitute. Both relays feature socketable mounting with plug-in termination, identical DPDT contact configuration, and 48VAC coil voltage. The substitute provides higher current rating (15A versus 10A) and faster switching times. Verify socket compatibility with your specific application hardware before implementation.

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

A: The primary differences are contact current rating (10A versus 15A), switching response times (25ms versus 13ms operate and 10ms release), operating temperature range (-25°C to 55°C versus -45°C to 70°C), and contact material composition (Silver Alloy versus Silver Cadmium Oxide). Both maintain identical coil voltage, contact form, and mounting type.

Q: Are both relays RoHS compliant?

A: Yes. The LY2 AC48 is RoHS Compliant, and the K10P-11A15-48 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the significance of the different switching voltage ratings?

A: The LY2 AC48 is rated for 250VAC and 125VDC maximum switching voltage, while the K10P-11A15-48 is rated for 120VAC maximum. For applications requiring switching of higher DC voltages, the LY2 AC48 provides greater capability. Verify your application's load voltage requirements against the appropriate relay specification.

Q: Do these relays require different socket types?

A: Both relays are socketable with plug-in termination. The K10P-11A15-48 additionally supports Quick Connect terminals at 0.187" (4.7mm). Confirm your application socket specification to ensure compatibility with either relay option.
