HP2-DC48V Equivalent & Substitute Parts

Part Overview

The HP2-DC48V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 48VDC coil and 10A contact rating. This socketable relay is designed for applications requiring reliable switching of AC and DC circuits. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HP2-DC48V is based on matching the following critical electrical and mechanical parameters:

• Coil Voltage: 48VDC (exact match required)
• Contact Form: DPDT (2 Form C) configuration (exact match required)
• Contact Rating: 10A minimum (exact match required)
• Coil Current: 26.7 mA (exact match required)
• Coil Resistance: 1.8 kOhms (exact match required)
• Mounting Type: Socketable (exact match required)
• Coil Type: Non Latching (exact match required)

The KUP-11D15-48 manufactured by TE Connectivity Potter & Brumfield Relays meets all critical substitution criteria. Both relays share identical coil voltage, contact configuration, current rating, coil current, and coil resistance specifications. Both are socketable, non-latching relays with plug-in quick connect termination, enabling direct functional equivalence in legacy system applications.

Parameter Comparison

Engineering Selection Recommendations

The KUP-11D15-48 is the qualified substitute for the obsolete HP2-DC48V. Both relays are functionally equivalent across all critical electrical parameters: 48VDC coil voltage, DPDT contact configuration, 10A contact rating, 26.7mA coil current, and 1.8kOhms coil resistance.

The KUP-11D15-48 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The substitute exhibits faster switching response times (15ms operate, 10ms release versus 25ms for both parameters on the original), an extended operating temperature range (-45°C to 70°C versus -50°C to 40°C), and higher switching voltage capability (240VAC maximum versus 250VAC nominal).

Minor differences exist in termination connector dimensions (0.187" versus 0.205") and contact material composition (AgCdO versus Ag). These differences do not affect functional substitution in standard socketable relay applications. The KUP-11D15-48 is RoHS non-compliant and REACH affected, whereas the HP2-DC48V is REACH unaffected; compliance requirements should be evaluated against specific application and regulatory mandates.

Frequently Asked Questions (FAQ)

Q: Can the KUP-11D15-48 directly replace the HP2-DC48V in existing equipment?

A: Yes. Both relays share identical coil voltage (48VDC), contact configuration (DPDT), current rating (10A), coil current (26.7mA), and coil resistance (1.8kOhms). Both are socketable with plug-in quick connect termination, enabling direct socket compatibility in legacy systems.

Q: What are the differences in switching performance?

A: The KUP-11D15-48 operates faster, with 15ms operate time and 10ms release time compared to 25ms for both parameters on the HP2-DC48V. This faster response may be advantageous in time-sensitive applications but does not prevent substitution in standard applications.

Q: Are there connector compatibility concerns?

A: The termination connectors differ slightly in dimension (0.187" on the KUP-11D15-48 versus 0.205" on the HP2-DC48V). Verify socket compatibility in the target application before installation.

Q: What is the difference in contact material?

A: The HP2-DC48V uses silver (Ag) contacts, while the KUP-11D15-48 uses silver cadmium oxide (AgCdO) contacts. Both materials are suitable for general purpose relay applications with 10A switching capacity.

Q: Does the extended operating temperature range of the KUP-11D15-48 affect substitution?

A: No. The KUP-11D15-48 operating range (-45°C to 70°C) encompasses the HP2-DC48V range (-50°C to 40°C) with extended upper temperature capability. This provides additional operational margin without affecting substitution validity.

Q: Are there compliance differences between the two relays?

A: Yes. The HP2-DC48V is REACH unaffected, while the KUP-11D15-48 is REACH affected and RoHS non-compliant. Evaluate compliance requirements against specific application and regulatory mandates before selection.
