APE3004H General Purpose Relay SPDT 4.5VDC Equivalent & Substitute Parts

Part Overview

The APE3004H is a general purpose relay manufactured by Panasonic Electric Works, featuring a single pole double throw (SPDT) contact configuration with a 4.5VDC coil. This through-hole mounted relay is rated for 6A switching current at 250VAC maximum and is designed for non-latching applications. The APE3004H is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Parameter Comparison

Engineering Selection Recommendations

The APF3034H is the appropriate substitute for the obsolete APE3004H. The substitute part maintains electrical and mechanical compatibility across all critical parameters while offering the advantage of active product status and RoHS compliance certification. The APF3034H's enhanced contact material composition (Silver Nickel with Gold plating) provides improved contact reliability compared to the silver alloy contacts of the original part. Current inventory availability of the APF3034H (11,500 pieces) ensures reliable procurement for replacement and new applications.

Frequently Asked Questions (FAQ)

Q: Can the APF3034H be used as a direct replacement for the APE3004H in existing designs?

A: Yes. The APF3034H maintains identical electrical specifications including coil voltage, contact configuration, current rating, and switching voltage. Both parts feature through-hole PC pin termination and operate within the same temperature range. The substitute part is mechanically and electrically compatible for direct board-level replacement.

Q: What is the difference in contact material between these two relays?

A: The APE3004H uses silver alloy contacts, while the APF3034H uses silver nickel with gold plating. The enhanced contact material in the APF3034H provides improved corrosion resistance and contact reliability, particularly in environments with higher humidity or corrosive atmospheres.

Q: Are there differences in coil operating characteristics?

A: The coil current is nearly identical (38 mA versus 37.8 mA). The must-operate voltage differs slightly (2.97 VDC for APE3004H versus 3.15 VDC for APF3034H). In applications with marginal coil voltage supply, this difference should be evaluated against actual circuit conditions. The must-release voltage and timing characteristics remain identical.

Q: What is the significance of the APF3034H being RoHS compliant?

A: RoHS compliance indicates the APF3034H meets restrictions on hazardous substances in electrical and electronic equipment. This certification is relevant for applications subject to environmental regulations and for integration into systems requiring RoHS-compliant component documentation.

Q: Does packaging differ between these parts?

A: The APE3004H packaging is not specified in available documentation. The APF3034H is supplied in tube packaging, which is standard for through-hole relay distribution. Confirm packaging requirements with your procurement specifications.
