APE1004H General Purpose Relay SPST 6A 4.5V

Part Overview

The APE1004H is a general purpose relay manufactured by Panasonic Electric Works, featuring a single-pole single-throw (SPST-NO) contact configuration rated for 6A at 250VAC maximum switching voltage with a 4.5VDC coil. This through-hole mounted relay operates with a coil current of 38mA and includes silver alloy contacts for reliable switching performance across industrial and commercial applications.

The APE1004H is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this relay.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APE1004H is determined by strict equivalence across the following critical parameters:

• Coil voltage specification (4.5VDC)
• Contact configuration (SPST-NO, 1 Form A)
• Current rating (6A minimum)
• Maximum switching voltage (250VAC)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Operating temperature range (-40°C to 85°C)
• Coil resistance (119 Ohms)

The APF1024H meets all substitution criteria. Both relays share identical coil voltage, contact form, current rating, switching voltage, mounting configuration, and operating temperature specifications. Coil current variance (37.8mA vs 38mA) and contact material difference (Silver Nickel vs Silver Alloy) remain within acceptable tolerance for general purpose relay applications. The APF1024H is currently in active production status with RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The APF1024H is the direct substitute for the obsolete APE1004H. Both relays are manufactured by Panasonic Electric Works and maintain functional equivalence across all critical electrical and mechanical parameters. The APF1024H offers the advantage of active production status, ensuring long-term supply chain availability and design continuity.

The APF1024H carries RoHS compliance certification, meeting current regulatory requirements for electronic component manufacturing. Both parts share identical ECCN (EAR99) and HTSUS (8536.41.0020) classifications, confirming regulatory equivalence for export and trade purposes.

The marginal difference in must-operate voltage (3.15VDC vs 2.97VDC) and contact material composition (Silver Nickel vs Silver Alloy) do not affect functional compatibility in general purpose relay applications operating within the specified 4.5VDC coil voltage range.

Frequently Asked Questions (FAQ)

Q: Can the APF1024H directly replace the APE1004H in existing circuit designs?

A: Yes. Both relays share identical coil voltage (4.5VDC), contact configuration (SPST-NO), current rating (6A), switching voltage (250VAC), and mounting specifications (Through Hole, PC Pin termination). Electrical and mechanical compatibility is confirmed.

Q: What is the significance of the contact material difference between Silver Alloy and Silver Nickel?

A: Both contact materials are standard for general purpose relay applications. Silver Nickel (AgNi) contacts in the APF1024H provide equivalent switching performance and reliability for the specified 6A current rating and 250VAC switching voltage. Contact material selection does not affect functional substitution.

Q: Why is the APE1004H classified as obsolete?

A: The APE1004H has been discontinued by Panasonic Electric Works. The APF1024H represents the current production equivalent, ensuring ongoing availability and support for applications requiring this relay specification.

Q: Are there compliance differences between the two relays?

A: The APF1024H is RoHS compliant, meeting current environmental and regulatory standards. Both relays share identical ECCN and HTSUS classifications. The APF1024H is the recommended choice for new designs and ongoing production requiring regulatory compliance documentation.

Q: What packaging options are available for the APF1024H?

A: The APF1024H is supplied in tube packaging. The APE1004H packaging specification was not provided. Confirm packaging requirements with your procurement process to ensure compatibility with assembly and handling procedures.

Q: Is the coil current difference (38mA vs 37.8mA) significant?

A: No. The 0.2mA variance is negligible and does not affect circuit design or component selection. Both relays operate within the same coil current specification range for general purpose applications.
