HC1E-PL-AC120V-F Equivalent & Substitute Parts

Part Overview

The HC1E-PL-AC120V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring SPDT (1 Form C) contact configuration with 120VAC coil voltage and 5A contact rating. This through-hole mounted relay includes a lighted indicator and is sealed for environmental protection. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the HC1E-PL-AC120V-F is based on the following critical parameters that must align for functional equivalence:

Primary Matching Criteria:

• Contact form: SPDT (1 Form C) configuration
• Coil voltage: 120VAC
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching

Secondary Compatibility Factors:

• Contact rating current: Equal to or greater than 5A
• Switching voltage: Equal to or greater than 250VAC
• Operating temperature range: Must encompass or exceed -40°C ~ 60°C
• Seal rating: Sealed construction preferred for environmental protection

The substitute part 2987901 (Phoenix Contact REL-MR series) satisfies all primary matching criteria and exceeds secondary compatibility requirements with higher current rating (16A) and extended temperature range (-40°C ~ 70°C).

Parameter Comparison

Engineering Selection Recommendations

The 2987901 (Phoenix Contact REL-MR series) is an active product suitable for substitution in applications currently using the obsolete HC1E-PL-AC120V-F. The substitute meets all functional requirements with the following considerations:

Advantages of substitution:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance supports modern manufacturing and environmental standards
• Higher contact rating (16A vs 5A) provides operational margin in current-carrying applications
• Reduced coil current (7mA vs 11.9mA) decreases power consumption
• Faster switching times (12ms operate, 8ms release vs 20ms each) improve response characteristics
• Extended operating temperature range (-40°C ~ 70°C vs -40°C ~ 60°C) supports broader environmental conditions

Design considerations:

• Verify mechanical fit and PCB layout compatibility due to potential dimensional differences between manufacturers
• Confirm that reduced coil current does not conflict with existing drive circuit design
• Assess whether faster switching times align with system timing requirements

Frequently Asked Questions (FAQ)

Q: Can the 2987901 directly replace the HC1E-PL-AC120V-F without circuit modification?

A: The 2987901 maintains electrical compatibility for the primary switching function (SPDT, 120VAC coil, PC pin termination). However, verify mechanical dimensions and PCB footprint compatibility. The reduced coil current (7mA vs 11.9mA) is advantageous and does not require circuit changes for standard drive circuits.

Q: What is the significance of the higher 16A contact rating on the substitute?

A: The 2987901 is rated for 16A continuous current versus 5A on the original part. This provides operational margin and allows the substitute to handle higher current loads without derating. Applications limited to 5A or less operate well within the substitute's capability.

Q: Does the faster switching time of the 2987901 affect system performance?

A: The 2987901 operates faster (12ms vs 20ms for operate time, 8ms vs 20ms for release time). In most general purpose relay applications, this improvement is beneficial. Verify that system timing logic does not depend on the original slower switching characteristics.

Q: Is the mechanical indicator on the 2987901 a functional difference?

A: The 2987901 includes both lighted and mechanical indicators, while the original has only a lighted indicator. The mechanical indicator provides visual feedback independent of electrical power, which is an enhancement for troubleshooting and system status verification.

Q: What compliance certifications should be verified for the substitute?

A: The 2987901 is ROHS3 compliant and REACH unaffected. Confirm that your application requirements align with these standards. The original HC1E-PL-AC120V-F compliance status should be cross-referenced with your system documentation.

Q: Are there packaging differences between the original and substitute?

A: The HC1E-PL-AC120V-F is specified with "-" packaging notation, while the 2987901 is supplied in bulk packaging. Verify that bulk packaging meets your procurement and handling requirements.
