ALZ11F48 Equivalent & Substitute Parts

Part Overview

The ALZ11F48 is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 48VDC coil and 16A contact rating. This through-hole mounted relay is designed for industrial control applications requiring reliable switching at 440VAC maximum. The part is currently active in production with 969 units in stock.

Equivalent and substitute parts are identified to provide procurement flexibility, support supply chain continuity, and accommodate design requirements across different manufacturing environments. Substitutes must maintain electrical compatibility across coil voltage, contact rating, contact form, and operating characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ALZ11F48 are qualified based on the following critical parameters:

Electrical Compatibility Requirements:

• Coil voltage: 48VDC (exact match required)
• Contact form: SPDT (1 Form C) (exact match required)
• Contact rating: 16 A minimum (exact match required)
• Must operate voltage: 33.6 VDC (exact match required)
• Must release voltage: 4.8 VDC (exact match required)
• Coil insulation class: Class F (exact match required)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (exact match required)
• Termination style: PC Pin (exact match required)
• Coil type: Non Latching (exact match required)

Regulatory Compliance:

• RoHS compliance status
• ECCN classification
• HTSUS code alignment

The identified substitutes (RTD14048 and 2-1415899-4) meet all critical electrical and mechanical parameters. Variations in switching voltage maximum, operate/release times, operating temperature upper limit, and contact material do not prevent functional substitution within the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts (ALZ11F48, 2-1415899-4, and RTD14048) are active products with current manufacturing status and full regulatory compliance. Selection between these parts should be based on the following factors:

ALZ11F48 (Panasonic Electric Works):

• Highest switching voltage rating (440VAC vs. 400VAC)
• Widest operating temperature range (-40°C to 105°C)
• Sealed with flux protection
• Longer operate time (15 ms vs. 8 ms)
• Suitable for applications requiring extended temperature operation or higher AC switching voltage

2-1415899-4 (TE Connectivity Potter & Brumfield):

• Faster switching response (8 ms operate time)
• Bulk packaging option
• Suitable for high-speed switching applications
• No seal rating specified

RTD14048 (TE Connectivity Potter & Brumfield):

• Fastest switching response (8 ms operate time)
• Fully sealed construction
• Silver Nickel contact material
• Tube packaging
• Suitable for sealed applications requiring rapid switching

All parts carry EAR99 ECCN classification and HTSUS code 8536.41.0050, indicating equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can RTD14048 replace ALZ11F48 in existing designs?

A: Yes. Both parts share identical coil voltage (48VDC), contact form (SPDT), contact rating (16A), must-operate voltage (33.6VDC), and must-release voltage (4.8VDC). The primary differences are operating temperature range (RTD14048 limited to 85°C vs. ALZ11F48 to 105°C), switching voltage maximum (400VAC vs. 440VAC), and contact material (Silver Nickel vs. Silver Tin Oxide). Substitution is valid for applications within the RTD14048 temperature and voltage envelope.

Q: What is the difference between 2-1415899-4 and RTD14048?

A: Both are TE Connectivity products with identical electrical specifications. The key differences are packaging (bulk vs. tube), seal rating (unspecified vs. fully sealed), and contact material (Silver Tin Oxide vs. Silver Nickel). RTD14048 offers sealed construction; 2-1415899-4 does not specify a seal rating.

Q: Are there packaging considerations for substitution?

A: Yes. ALZ11F48 and RTD14048 are supplied in tube packaging, while 2-1415899-4 is supplied in bulk. Tube packaging is preferred for automated assembly and component traceability. Bulk packaging may require additional handling and sorting procedures.

Q: Do all substitutes meet RoHS requirements?

A: Yes. ALZ11F48 is RoHS Compliant; both TE Connectivity parts (2-1415899-4 and RTD14048) are ROHS3 Compliant. All parts meet current RoHS directives.

Q: What is the impact of different operating temperature ranges?

A: ALZ11F48 operates to 105°C, while both TE Connectivity substitutes operate to 85°C maximum. Applications requiring operation above 85°C must use ALZ11F48. For applications with maximum ambient temperatures below 85°C, all three parts are suitable.

Q: How do switching voltage differences affect substitution?

A: ALZ11F48 is rated for 440VAC maximum switching voltage; both TE Connectivity parts are rated for 400VAC maximum. Applications requiring switching above 400VAC must use ALZ11F48. For applications at or below 400VAC, all three parts are suitable.
