HL2-PL-DC12V Equivalent & Substitute Parts

Part Overview

The HL2-PL-DC12V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 12VDC coil and 10A contact rating. This through-hole mounted relay is designed for standard switching applications requiring dual-pole, dual-throw functionality. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HL2-PL-DC12V is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 12VDC
• Contact Form: DPDT (2 Form C)
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Coil Type: Non Latching
• Coil Resistance: 160 Ohms
• Coil Current: 75 mA

Allowable Variation Parameters:

• Contact Rating (Current): Substitute must equal or exceed 10A
• Switching Voltage: Substitute must support minimum 125VAC operation
• Operating Temperature Range: Substitute must cover or exceed the -50°C ~ 70°C range
• Operate/Release Time: Minor variations acceptable within typical relay performance tolerances

The K10P-11D55-12 from TE Connectivity Potter & Brumfield Relays meets all mandatory matching criteria and exceeds performance specifications in contact rating (15A vs. 10A) and switching voltage capability (120VAC max vs. 125VAC nom).

Parameter Comparison

Engineering Selection Recommendations

The K10P-11D55-12 is a direct functional substitute for the obsolete HL2-PL-DC12V based on electrical and mechanical parameter alignment. The substitute part offers the following advantages:

• Active product status with current manufacturing and availability (2811 pcs in stock vs. 1022 pcs for the obsolete part)
• Higher contact rating (15A vs. 10A) provides additional margin for switching applications
• Identical coil specifications (12VDC, 160 Ohms, 75 mA) ensure direct circuit compatibility
• Matching DPDT contact form and through-hole PC pin termination enable direct PCB mounting replacement

Considerations for implementation:

• Operating temperature minimum is -45°C (vs. -50°C for original part); verify application requirements if operation below -45°C is necessary
• Contact material differs (Silver Cadmium Oxide vs. Silver Alloy); this affects contact resistance and arc suppression characteristics but does not prevent substitution for general purpose switching
• Operate and release times are slightly longer (13ms and 10ms vs. 10ms and 5ms); verify timing-critical applications can tolerate these variations
• RoHS compliance status differs; verify regulatory requirements for your application

Frequently Asked Questions (FAQ)

Q: Can the K10P-11D55-12 directly replace the HL2-PL-DC12V without circuit modifications?

A: Yes. Both relays share identical coil voltage (12VDC), coil resistance (160 Ohms), contact form (DPDT), and termination style (PC Pin). Direct PCB mounting replacement is possible without circuit redesign.

Q: Why does the substitute part have a higher current rating (15A vs. 10A)?

A: The K10P-11D55-12 is rated for 15A contact current, exceeding the original 10A specification. This provides additional safety margin and does not prevent substitution; the relay will function correctly in applications designed for 10A switching.

Q: Are there differences in switching performance between these relays?

A: Yes. The K10P-11D55-12 has slightly longer operate time (13ms vs. 10ms) and release time (10ms vs. 5ms). For applications with strict timing requirements, these differences must be evaluated. For general purpose switching, these variations are typically acceptable.

Q: What is the significance of the different contact materials?

A: The original part uses Silver Alloy contacts; the substitute uses Silver Cadmium Oxide (AgCdO). AgCdO provides superior arc suppression and contact erosion resistance, particularly beneficial for inductive load switching. This material difference does not prevent substitution for general purpose applications.

Q: Does the operating temperature range difference affect compatibility?

A: The substitute part operates from -45°C to 70°C, while the original operates from -50°C to 70°C. If your application requires operation below -45°C, the substitute may not be suitable. For most industrial and commercial applications, the -45°C minimum is sufficient.

Q: What is the packaging difference between these parts?

A: The HL2-PL-DC12V is supplied with standard packaging; the K10P-11D55-12 is supplied in trays. This affects handling and storage but does not impact electrical or mechanical compatibility.

Q: Are there compliance or regulatory differences I should consider?

A: The K10P-11D55-12 is RoHS non-compliant and REACH affected, while the original part is REACH unaffected. Verify your application's regulatory requirements before selecting the substitute.
