HP3-DC12V Equivalent & Substitute Parts

Part Overview

The HP3-DC12V is a general purpose 3PDT relay manufactured by Panasonic Electric Works, designed for socketable mounting with a 12VDC coil and 10A contact rating. This relay operates at 250VAC nominal switching voltage with 3 Form C contacts and non-latching coil type. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring compatible functionality.

Substitute Part Grouping Explanation

Substitute parts for the HP3-DC12V are qualified based on the following critical parameters that must match or exceed the main part specifications:

Coil Voltage: Must be 12VDC
Contact Form: Must be 3PDT (3 Form C)
Contact Rating: Must be 10A minimum
Mounting Type: Must be Socketable
Termination Style: Must be Plug In, Quick Connect - 0.187" (4.7mm)
Coil Type: Must be Non Latching

The KUP-14D15-12 and KUP-14D45-12 from TE Connectivity Potter & Brumfield Relays meet all critical substitution criteria. Both parts are active products with identical coil voltage, contact form, current rating, mounting configuration, and termination style. The KUP-14D45-12 includes additional features (lighted indicator and test button) but maintains full electrical and mechanical compatibility.

Engineering Selection Recommendations

Both KUP-14D15-12 and KUP-14D45-12 are qualified substitutes for the obsolete HP3-DC12V. Selection between the two TE Connectivity alternatives depends on application requirements:

KUP-14D15-12 is the baseline equivalent, offering identical electrical performance with ROHS3 compliance and REACH Affected status. This part provides direct functional replacement with improved operating temperature range (-45°C to 70°C versus -50°C to 40°C) and faster switching times (15ms operate, 10ms release versus 30ms for both).

KUP-14D45-12 provides the same electrical and mechanical compatibility as KUP-14D15-12 with the addition of a lighted indicator and test button. This variant is suitable for applications requiring visual status indication or manual testing capability. ROHS3 compliance is confirmed; REACH status is vendor undefined.

Both substitute parts feature lower coil current (100mA versus 120mA) and higher must-operate voltage (9VDC versus 9.6VDC), representing improved efficiency and tighter operating margins. Contact material differs (AgCdO versus Ag), which is acceptable for general purpose relay applications at the specified voltage and current ratings.

Frequently Asked Questions (FAQ)

Q: Can KUP-14D15-12 or KUP-14D45-12 directly replace HP3-DC12V in existing sockets?

A: Yes. Both substitute parts are socketable with identical 0.187" (4.7mm) quick connect termination and 3PDT contact configuration, enabling direct socket compatibility with HP3-DC12V installations.

Q: What is the difference between KUP-14D15-12 and KUP-14D45-12?

A: Both parts are electrically and mechanically identical. KUP-14D45-12 includes a lighted indicator and test button for visual status monitoring and manual testing. Select KUP-14D45-12 if these features are required; otherwise, KUP-14D15-12 provides equivalent functionality.

Q: Are the substitute parts RoHS compliant?

A: Both KUP-14D15-12 and KUP-14D45-12 are ROHS3 compliant. The original HP3-DC12V RoHS status is not specified in available documentation.

Q: How do the switching voltage ratings compare?

A: HP3-DC12V is rated 250VAC nominal. Both substitute parts are rated 240VAC maximum. For applications operating at or near 250VAC, verify that 240VAC maximum rating is acceptable for your specific load conditions.

Q: What are the coil current differences?

A: HP3-DC12V requires 120mA coil current; both substitute parts require 100mA. This represents a 17% reduction in coil power consumption, which may require driver circuit adjustment if the original design was margin-critical.

Q: Are there temperature range considerations?

A: HP3-DC12V operates -50°C to 40°C. Both substitute parts operate -45°C to 70°C, providing a wider upper temperature range but slightly narrower lower temperature range. Verify compatibility with your application's thermal environment.

Q: What is the REACH compliance status?

A: KUP-14D15-12 is REACH Affected. KUP-14D45-12 is vendor undefined for REACH status. Confirm REACH requirements with your supply chain or regulatory team if applicable to your end market.
