ALE75B05 Equivalent & Substitute Parts

Part Overview

The ALE75B05 is a general purpose relay manufactured by Panasonic Electric Works, featuring a SPST-NO (1 Form A) contact configuration with a 5VDC coil. This through-hole mounted relay is rated for 16A at 277VAC maximum switching voltage, delivering 4432VA maximum load switching capacity. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this relay specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALE75B05 is determined by strict equivalence across the following critical parameters:

• Coil Voltage: Must be 5VDC to ensure direct compatibility with existing circuit designs
• Contact Form: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Contact Rating (Current): Must be rated for minimum 16A to handle specified load requirements
• Mounting Type: Must be through-hole to fit existing PCB layouts
• Termination Style: Must use PC Pin termination for direct socket compatibility
• Coil Type: Must be non-latching to preserve relay behavior

The G5PZ-1A DC5 from Omron Electronics Inc-EMC Div meets all these critical parameters, establishing it as a direct functional equivalent despite differences in secondary characteristics such as coil current, operate/release times, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The G5PZ-1A DC5 serves as a direct functional substitute for the obsolete ALE75B05 based on matching core electrical and mechanical specifications. Both relays share identical coil voltage, contact configuration, current rating, and mounting characteristics required for circuit-level compatibility.

The G5PZ-1A DC5 carries active product status with ROHS3 compliance, ensuring continued availability and regulatory alignment for new designs and system updates. The Omron relay is sealed with flux protection, providing enhanced environmental protection compared to the original Panasonic design.

Designers must account for the following differences when implementing the G5PZ-1A DC5:

• Maximum switching voltage is 250VAC versus 277VAC on the original part. Applications operating at or near 277VAC must be evaluated for margin adequacy.
• Operating temperature range is -40°C to 70°C versus -40°C to 85°C. Systems requiring operation above 70°C require alternative solutions.
• Coil current is 106 mA versus 40 mA, requiring verification that drive circuits can supply the higher current demand.
• Coil resistance is 47 Ohms versus 125 Ohms, affecting circuit impedance and timing characteristics.

Both parts carry identical ECCN and HTSUS classifications, maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the G5PZ-1A DC5 be used as a direct drop-in replacement for the ALE75B05?

A: The G5PZ-1A DC5 is mechanically and electrically compatible for through-hole PCB mounting and shares identical coil voltage, contact form, and current rating. However, the higher coil current (106 mA vs. 40 mA) requires confirmation that existing drive circuits can supply this increased demand. The lower maximum switching voltage (250VAC vs. 277VAC) must be evaluated for applications operating near the upper voltage limit.

Q: What is the primary reason for substituting the ALE75B05?

A: The ALE75B05 is obsolete and no longer manufactured by Panasonic Electric Works. The G5PZ-1A DC5 is an active product from Omron with equivalent functional specifications, ensuring long-term availability for maintenance and new implementations.

Q: Are there packaging differences between these relays?

A: The ALE75B05 is supplied in bulk packaging, while the G5PZ-1A DC5 is supplied in tray packaging. Both use identical PC Pin termination for through-hole mounting. Inventory availability differs, with 2153 units of the G5PZ-1A DC5 currently in stock versus the obsolete ALE75B05.

Q: How do the operating temperature ranges differ?

A: The ALE75B05 operates from -40°C to 85°C, while the G5PZ-1A DC5 operates from -40°C to 70°C. Applications requiring operation above 70°C cannot use the Omron substitute without additional thermal management or alternative component selection.

Q: What compliance certifications apply to both relays?

A: The ALE75B05 holds CSA, TUV, UR, and VDE approvals. The G5PZ-1A DC5 carries ROHS3 compliance. Both relays are classified as EAR99 for export control and share the same HTSUS tariff code 8536.41.0050.
