HL2-HP-DC48V General Purpose Relay DPDT 48VDC Equivalent & Substitute Parts

Part Overview

The HL2-HP-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 through-hole mounted relay is designed for switching applications requiring dual-pole, dual-throw functionality at 48 volts DC.

The HL2-HP-DC48V is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this relay.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HL2-HP-DC48V is determined by the following critical parameters:

Primary Compatibility Criteria:

• Coil voltage: 48VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Mounting type: Through hole (exact match required)
• Termination style: PC pin (exact match required)

Secondary Compatibility Criteria:

• Contact rating current: Must be equal to or greater than 10A
• Must operate voltage: Must not exceed 38.4 VDC
• Must release voltage: Must not exceed 4.8 VDC
• Operating temperature range: Must encompass or match the original range

Two substitute parts meet these criteria:

JW2SN-DC48V (Panasonic Electric Works): Matches all primary criteria. Contact rating of 5A is below the original 10A specification, limiting this substitute to applications with reduced current requirements.

K10P-11D55-48 (TE Connectivity Potter & Brumfield Relays): Matches all primary criteria. Contact rating of 15A exceeds the original 10A specification, providing higher current capacity for the same switching function.

Parameter Comparison

Engineering Selection Recommendations

K10P-11D55-48 is the primary substitute for the HL2-HP-DC48V. Both parts share identical coil resistance (2.6 kOhms), matching coil current (18.5 mA), and equivalent must-operate voltage specifications. The K10P-11D55-48 is active in production, ROHS3 compliant, and provides 15A contact rating, exceeding the original 10A specification. The operating temperature range of -45°C ~ 70°C encompasses the original -50°C ~ 70°C range at the lower bound by 5°C, which is acceptable for most industrial applications.

JW2SN-DC48V is a secondary substitute suitable only for applications where the circuit load does not exceed 5A. This part is active in production and ROHS3 compliant. The reduced coil current (11 mA versus 18.5 mA) and lower must-operate voltage (33.6 VDC) may provide advantages in low-power control circuits. The operating temperature range of -40°C ~ 60°C is narrower than the original specification and does not support the full -50°C lower temperature requirement.

Both substitute parts are available in active production status, ensuring supply chain continuity compared to the obsolete HL2-HP-DC48V.

Frequently Asked Questions (FAQ)

Q: Can the JW2SN-DC48V replace the HL2-HP-DC48V in all applications?

A: No. The JW2SN-DC48V has a maximum contact rating of 5A, while the HL2-HP-DC48V is rated for 10A. The JW2SN-DC48V is suitable only for applications where the switching current does not exceed 5A. Additionally, the JW2SN-DC48V operating temperature range (-40°C ~ 60°C) does not support operation below -40°C, whereas the original part operates to -50°C.

Q: Is the K10P-11D55-48 a direct replacement for the HL2-HP-DC48V?

A: The K10P-11D55-48 is functionally compatible as a substitute. Both parts share the same coil voltage (48VDC), contact form (DPDT), mounting type (through hole), and termination style (PC pin). The K10P-11D55-48 provides higher contact rating (15A versus 10A) and is in active production. The operating temperature range differs by 5°C at the lower bound (-45°C versus -50°C).

Q: What is the impact of different contact materials on substitution?

A: The HL2-HP-DC48V uses silver alloy contacts, while the K10P-11D55-48 uses silver cadmium oxide (AgCdO) and the JW2SN-DC48V uses silver nickel (AgNi). Contact material affects switching characteristics, load capacity, and environmental performance. Selection should be based on the specific switching load and environmental conditions of the application.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the K10P-11D55-48 and JW2SN-DC48V are ROHS3 compliant. The original HL2-HP-DC48V RoHS status is not specified in the available data.

Q: What is the significance of the coil resistance difference between the HL2-HP-DC48V and JW2SN-DC48V?

A: The HL2-HP-DC48V has a coil resistance of 2.6 kOhms, while the JW2SN-DC48V has 4.4 kOhms. The higher resistance in the JW2SN-DC48V results in lower coil current (11 mA versus 18.5 mA) at the same 48VDC supply voltage. This affects power consumption and heat generation in the coil. The K10P-11D55-48 matches the original coil resistance at 2.6 kOhms.

Q: Can I use the K10P-11D55-48 in applications requiring operation below -45°C?

A: The K10P-11D55-48 is rated for operation down to -45°C, while the original HL2-HP-DC48V operates to -50°C. If the application requires operation at temperatures below -45°C, the K10P-11D55-48 is not suitable. In such cases, alternative parts with lower temperature ratings must be evaluated.
