APE30148 Equivalent & Substitute Parts

Part Overview

The APE30148 is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 48VDC coil and 6A contact rating. This through-hole mounted relay is designed for applications requiring reliable switching at 250VAC maximum. The APE30148 is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The APE30148 can be substituted with the APF30348 based on the following critical parameters that determine functional equivalence:

Matching Parameters:

• Coil voltage: 48VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 6 A
• Switching voltage: 250VAC - Max
• Coil type: Non Latching
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -40°C ~ 85°C
• Coil resistance: 10.62 kOhms
• Operate and release times: 8 ms / 4 ms

Allowable Variations:

• Coil current: APE30148 (5 mA) vs APF30348 (4.5 mA) — lower current in substitute reduces power consumption
• Contact material: APE30148 (Silver Alloy) vs APF30348 (Silver Nickel/Gold) — enhanced contact material in substitute provides improved reliability
• Must operate voltage: APE30148 (31.68 VDC) vs APF30348 (33.6 VDC) — both within acceptable operating margins
• Product status: APE30148 (Obsolete) vs APF30348 (Active) — substitute is currently manufactured

Parameter Comparison

Engineering Selection Recommendations

The APF30348 is the direct substitute for the obsolete APE30148. Both components are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications for all critical switching parameters.

Selection Basis:

The APF30348 is recommended for new designs and replacement applications because it maintains active production status, ensuring long-term availability and supply chain continuity. The APE30148, classified as obsolete, presents sourcing risk and limited inventory availability.

The APF30348 features enhanced contact material (Silver Nickel with Gold plating) compared to the APE30148 (Silver Alloy), providing improved contact reliability and longevity. The reduced coil current (4.5 mA vs 5 mA) in the APF30348 results in lower power consumption without compromising switching performance.

Both relays operate within the same temperature range (-40°C to 85°C) and maintain identical timing characteristics (8 ms operate, 4 ms release). The through-hole mounting and PC pin termination are identical, ensuring direct mechanical compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the APF30348 directly replace the APE30148 in existing designs?

A: Yes. The APF30348 is a direct functional equivalent with identical coil voltage (48VDC), contact configuration (SPDT), current rating (6A), and switching voltage (250VAC). Through-hole mounting and PC pin termination are identical, allowing direct PCB substitution.

Q: What are the differences between these two relays?

A: The primary differences are product status and contact material. The APE30148 is obsolete; the APF30348 is active production. The APF30348 uses Silver Nickel with Gold plating for enhanced contact durability, while the APE30148 uses Silver Alloy. The APF30348 also draws slightly less coil current (4.5 mA vs 5 mA).

Q: Are there packaging differences?

A: Yes. The APE30148 is supplied in bulk packaging, while the APF30348 is supplied in tube packaging. This does not affect electrical or mechanical function and is determined by supplier preference.

Q: What is the significance of the different "Must Operate Voltage" specifications?

A: The APE30148 requires 31.68 VDC minimum to operate, while the APF30348 requires 33.6 VDC. Both values are within acceptable operating margins for 48VDC coil relays and do not present compatibility issues in standard applications.

Q: Is the APF30348 RoHS compliant?

A: The APF30348 is ROHS3 compliant. The APE30148 REACH status is listed as unaffected. For applications requiring specific regulatory compliance, verify requirements against your system specifications.

Q: Can I use the APF30348 in high-temperature applications?

A: Both relays operate across the identical temperature range of -40°C to 85°C. For applications requiring operation outside this range, alternative relay types must be evaluated.
