HG4-DC110V-F Equivalent & Substitute Parts

Part Overview

The HG4-DC110V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a 4PDT (4 Form C) contact configuration with a 110VDC coil and 20A contact rating. This socketable relay is designed for industrial control applications requiring multiple independent switching circuits. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HG4-DC110V-F is evaluated based on the following critical parameters:

Mandatory Matching Criteria:

• Coil voltage: 110VDC
• Contact form: 4PDT (4 Form C)
• Mounting type: Socketable
• Coil type: Non Latching

Allowable Variation Parameters:

• Contact rating current: The substitute may have a lower current rating if the application does not require the full 20A capacity
• Switching voltage: Variation acceptable if minimum requirements are met
• Termination connector size: Different quick-connect pin sizes are acceptable if mechanical compatibility with the socket is verified
• Operating temperature range: Variation acceptable if application temperature requirements fall within the substitute's range
• Coil current and resistance: Variation acceptable within normal design tolerances
• Operate and release times: Variation acceptable if application timing requirements are met

The KUP-17D19-110 meets the mandatory matching criteria with the exception of contact rating current (10A versus 20A), making it suitable only for applications where the lower current capacity is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The KUP-17D19-110 is an active product from TE Connectivity Potter & Brumfield Relays and represents a viable substitute for the obsolete HG4-DC110V-F in applications where the following conditions are met:

Compatibility Requirements:

• The application load current does not exceed 10A per contact
• The socket accommodation allows for the 0.110" (2.8mm) quick-connect termination pins
• The operating temperature range of -45°C ~ 50°C encompasses the application requirements
• The faster operate and release times (15ms and 10ms respectively) are acceptable or beneficial to the application

Compliance Status: Both parts share identical ECCN (EAR99) and HTSUS classifications. The KUP-17D19-110 carries RoHS3 compliance, whereas the HG4-DC110V-F status is not specified. Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints.

Limitations: The KUP-17D19-110 has a reduced contact current rating of 10A compared to the 20A rating of the HG4-DC110V-F. This substitution is not suitable for applications requiring the full 20A switching capacity. Additionally, the different termination pin sizes require verification of socket compatibility before implementation.

Frequently Asked Questions (FAQ)

Q: Can the KUP-17D19-110 directly replace the HG4-DC110V-F in all applications?

A: No. The KUP-17D19-110 has a maximum contact rating of 10A, while the HG4-DC110V-F is rated for 20A. Substitution is only valid for applications where the actual load current per contact does not exceed 10A.

Q: Are the quick-connect termination pins compatible between these two relays?

A: No. The HG4-DC110V-F uses 0.250" (6.3mm) quick-connect pins, while the KUP-17D19-110 uses 0.110" (2.8mm) pins. Socket compatibility must be verified before substitution.

Q: What is the impact of the different operate and release times?

A: The KUP-17D19-110 has faster switching times (15ms operate, 10ms release) compared to the HG4-DC110V-F (40ms for both). This faster response may be beneficial in timing-sensitive applications but must be evaluated against application requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts share the same ECCN (EAR99) and HTSUS classifications. The KUP-17D19-110 is RoHS3 compliant. Both have MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints.

Q: What is the coil voltage tolerance for the KUP-17D19-110?

A: The KUP-17D19-110 must operate at 82.5VDC minimum. The HG4-DC110V-F must operate at 88VDC minimum. Both relays will function within a 110VDC nominal supply, but the KUP-17D19-110 has a lower minimum operating threshold.

Q: Can the different contact materials (AgSnO versus AgCdO) affect performance?

A: Contact material differences may affect performance in specific load conditions, including inductive loads, arc resistance, and contact wear characteristics. Application-specific testing is necessary to confirm suitability.
