ALE75F05 Equivalent & Substitute Parts

Part Overview

The ALE75F05 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 and is designed for non-latching applications. The part is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALE75F05 is based on the following critical parameters that must remain consistent or be exceeded:

• Coil voltage: 5VDC (exact match required)
• Contact form: SPST-NO (1 Form A) (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pin (exact match required)
• Switching voltage: 277VAC maximum (must equal or exceed)
• Operating temperature range: Must encompass or exceed -40°C ~ 85°C
• Contact current rating: Must equal or exceed 16A
• Coil insulation class: Class F (preferred for thermal compatibility)

The T9AS1D14-5 qualifies as a substitute because it maintains the same coil voltage, contact form, mounting type, and termination style while exceeding the current rating and maintaining compatible electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The T9AS1D14-5 is a direct substitute for the ALE75F05 based on the following engineering criteria:

• Both relays maintain identical coil voltage (5VDC), contact form (SPST-NO), mounting configuration (through-hole PC pin), and maximum switching voltage (277VAC).
• The T9AS1D14-5 exceeds the current rating requirement, providing 30A versus the original 16A specification, ensuring adequate margin for the application.
• The T9AS1D14-5 is currently in active production status, providing long-term availability and supply chain stability compared to the obsolete ALE75F05.
• Both parts maintain Class F coil insulation and are RoHS compliant, with the T9AS1D14-5 meeting the more recent ROHS3 standard.
• The T9AS1D14-5 features a fully sealed design, providing enhanced environmental protection compared to the original part.
• Operating temperature range of the T9AS1D14-5 (-55°C ~ 85°C) exceeds the original specification, supporting broader application environments.

Frequently Asked Questions (FAQ)

Q: Can the T9AS1D14-5 be used as a direct replacement for the ALE75F05 in existing PCB designs?

A: Yes. Both relays share identical through-hole PC pin termination, coil voltage (5VDC), contact form (SPST-NO), and maximum switching voltage (277VAC). The footprint and electrical interface are compatible without PCB modification.

Q: What is the impact of the higher coil current (200 mA vs. 40 mA) in the T9AS1D14-5?

A: The T9AS1D14-5 requires higher coil current due to its lower coil resistance (25 Ohms vs. 125 Ohms). The driving circuit must supply 200 mA at 5VDC to operate the relay. Verify that the control circuit can provide this current level before substitution.

Q: Does the increased current rating (30A vs. 16A) affect circuit operation?

A: No. The higher current rating of the T9AS1D14-5 provides additional safety margin and does not affect circuit operation. The relay will switch at the same voltage and contact form as the original part.

Q: What is the significance of the fully sealed design in the T9AS1D14-5?

A: The sealed design provides enhanced protection against moisture, dust, and environmental contaminants. This improves reliability in harsh operating conditions compared to the unsealed ALE75F05.

Q: Are there any timing differences between these relays?

A: The T9AS1D14-5 has faster operate and release times (15 ms each) compared to the ALE75F05 (20 ms operate, 25 ms release). This faster switching may be beneficial for time-sensitive applications but should be verified against system requirements.

Q: Is the T9AS1D14-5 available in the same packaging as the ALE75F05?

A: The T9AS1D14-5 is supplied in bulk packaging, while the ALE75F05 packaging specification was not provided. Both use identical through-hole PC pin termination suitable for standard PCB assembly processes.
