NF4EB-48V Equivalent & Substitute Parts

Part Overview

The NF4EB-48V is a general purpose relay manufactured by Panasonic Electric Works, featuring a 4PDT (4 Form C) contact configuration with 2A contact rating and 48VDC coil voltage. This through-hole mounted relay is designed for industrial control and switching applications requiring multiple independent circuits. The product is currently obsolete, making equivalent substitute parts necessary for maintenance, repair, and legacy system support where original components are no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NF4EB-48V is determined by the following critical parameters:

• Coil Voltage: 48VDC (exact match required)
• Contact Form: 4PDT (4 Form C) configuration (exact match required)
• Contact Rating: 2 A minimum (equal or higher acceptable)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Coil Type: Non Latching (exact match required)

The V23030A1026A104 manufactured by TE Connectivity Potter & Brumfield Relays meets all critical substitution criteria. Both relays share identical coil voltage, contact configuration, current rating, mounting method, and termination style. Operational characteristics differ within acceptable ranges for general purpose relay applications.

Parameter Comparison

Engineering Selection Recommendations

The V23030A1026A104 is a direct functional equivalent for the NF4EB-48V in applications requiring 48VDC 4PDT relay switching. Both components are obsolete products with identical core electrical specifications: 48VDC coil voltage, 4PDT contact configuration, 2A contact rating, through-hole mounting, and PC pin termination.

The V23030A1026A104 offers improved switching voltage capability (250VAC/250VDC versus 220VAC/220VDC) and faster response characteristics (8ms operate time versus 15ms, 2ms release time versus 10ms). The substitute part operates at lower coil voltage threshold (32VDC must-operate versus 38.4VDC) and supports a wider operating temperature range (-40°C to 70°C versus -40°C to 65°C).

Both relays feature identical contact materials (Silver/Gold) and moisture sensitivity ratings (MSL 1 - Unlimited), ensuring compatibility in standard industrial control environments. The V23030A1026A104 is RoHS Compliant, providing environmental compliance advantage for new designs or system upgrades.

Frequently Asked Questions (FAQ)

Q: Can the V23030A1026A104 directly replace the NF4EB-48V in existing circuits?

A: Yes. Both relays share identical coil voltage (48VDC), contact configuration (4PDT), current rating (2A), mounting type (through-hole), and termination style (PC pin). Physical footprint and electrical interface are compatible for direct substitution on PCBs designed for the NF4EB-48V.

Q: What are the key differences between these two relays?

A: The V23030A1026A104 features higher maximum switching voltage (250VAC/250VDC versus 220VAC/220VDC), faster response times (8ms operate, 2ms release versus 15ms operate, 10ms release), lower coil current draw (17.8mA versus 11.5mA), and wider operating temperature range (-40°C to 70°C versus -40°C to 65°C). Coil resistance differs (2.7kOhms versus 4.2kOhms).

Q: Are there any compliance or certification differences?

A: The V23030A1026A104 is RoHS Compliant. Both relays carry MSL 1 (Unlimited) moisture sensitivity rating and ECCN EAR99 classification. Both are classified under HTSUS 8536.41.0020.

Q: Which relay should be selected for new designs?

A: The V23030A1026A104 is recommended for new designs due to RoHS compliance status and superior performance characteristics. However, both products are obsolete, requiring evaluation of current-production alternatives for long-term system reliability.

Q: Do these relays require different PCB footprints?

A: No. Both relays use identical through-hole PC pin termination and are designed for standard relay socket mounting. PCB layouts designed for the NF4EB-48V accommodate the V23030A1026A104 without modification.
