HP3-DC110V Equivalent & Substitute Parts

Part Overview

The HP3-DC110V is a general purpose 3PDT relay manufactured by Panasonic Electric Works, designed for 110VDC coil operation with 10A contact rating. This socketable relay features 3 Form C contacts and operates across -50°C to 40°C. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HP3-DC110V is determined by the following critical parameters:

• Coil voltage must be 110VDC
• 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

All four substitute parts (KUP-14D15-110, KUP-14D35-110, KUP-14D35F-110, KUP-14D45-110) manufactured by TE Connectivity Potter & Brumfield Relays meet these core electrical and mechanical requirements. These parts are active products with current availability, providing direct functional equivalence to the obsolete HP3-DC110V.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts provide functional equivalence to the HP3-DC110V for applications requiring 110VDC 3PDT 10A socketable relays. Selection among substitutes should consider the following factors:

KUP-14D15-110: Basic equivalent without additional features. Suitable for applications where lighted indicator or test button functionality is not required. RoHS non-compliant status should be evaluated against regulatory requirements.

KUP-14D35-110: Includes lighted indicator feature. RoHS non-compliant. Appropriate for applications requiring visual relay status indication without test capability.

KUP-14D35F-110: Includes lighted indicator with gold-plated contact option. ROHS3 compliant and recommended for new designs subject to RoHS regulations. Vendor-undefined REACH status requires clarification for restricted substance compliance.

KUP-14D45-110: Includes both lighted indicator and test button features. ROHS3 compliant. Provides enhanced diagnostics capability for field testing and maintenance. Suitable for applications requiring manual relay verification.

All substitutes operate faster (15 ms operate, 10 ms release) compared to the original HP3-DC110V (30 ms operate and release), which may require timing verification in control circuits. All substitutes support extended operating temperature range (-45°C to 70°C) compared to the original (-50°C to 40°C).

Frequently Asked Questions (FAQ)

Q: Can KUP-14D series relays directly replace HP3-DC110V in existing sockets?

A: Yes. All KUP-14D substitute parts feature identical socketable mounting type and 0.187" (4.7mm) quick connect termination, enabling direct socket compatibility with HP3-DC110V installations.

Q: What is the impact of faster switching times in KUP-14D relays?

A: KUP-14D relays operate in 15 ms and release in 10 ms, compared to 30 ms for both operations in the HP3-DC110V. Applications with timing-critical circuits should verify that faster switching does not affect system performance or introduce unintended state changes.

Q: Are there differences in contact material between the original and substitutes?

A: Yes. The HP3-DC110V uses silver (Ag) contacts, while KUP-14D15-110, KUP-14D35-110, and KUP-14D45-110 use silver cadmium oxide (AgCdO). KUP-14D35F-110 offers both AgCdO and gold (Au) plating. Contact material selection affects load capacity and environmental resistance; verify compatibility with specific switching loads.

Q: Which substitute is recommended for new designs?

A: KUP-14D35F-110 is recommended for new designs due to ROHS3 compliance, supporting modern regulatory requirements. KUP-14D45-110 is recommended when field diagnostics and manual testing capability are required.

Q: What is the difference between KUP-14D35-110 and KUP-14D35F-110?

A: Both include lighted indicator functionality. KUP-14D35F-110 offers gold-plated contacts and ROHS3 compliance, while KUP-14D35-110 is RoHS non-compliant. Contact material and regulatory status are the primary distinctions.

Q: How does coil current difference affect power supply design?

A: The HP3-DC110V draws 14.9 mA, while all KUP-14D substitutes draw 11 mA. This 3.9 mA reduction may allow use of lower-capacity power supplies or reduce thermal load in coil circuits. Existing power supplies rated for 14.9 mA will operate the substitutes with margin.

Q: Are packaging differences significant for procurement?

A: KUP-14D15-110, KUP-14D35-110, and KUP-14D35F-110 are supplied in bulk packaging, while KUP-14D45-110 is supplied in trays. Packaging affects handling and storage but does not impact electrical or mechanical compatibility.
