ALZ11F05W Equivalent & Substitute Parts

Part Overview

The ALZ11F05W is a general purpose relay manufactured by Panasonic Electric Works, featuring SPDT (1 Form C) contact configuration with 16A switching capacity at 5VDC coil voltage. This through-hole mounted relay is designed for industrial control applications requiring sealed, flux-protected switching contacts. The part is currently active in production with 714 units in stock.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits functional alternatives. Substitute relays must maintain compatibility across coil voltage, contact form, current rating, and termination style to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ALZ11F05W are qualified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• Coil Voltage: 5VDC (exact match required)
• Contact Form: SPDT (1 Form C) (exact match required)
• Contact Rating: 16 A (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Coil Type: Non Latching (exact match required)

Secondary Compatibility Parameters:

• Coil Insulation Class: Class F (maintained across all substitutes)
• Must Operate Voltage: 4.6 VDC (maintained across all substitutes)
• Must Release Voltage: 0.5 VDC (maintained across all substitutes)
• Relay Type: General Purpose (maintained across all substitutes)

All three substitute parts (5-1415899-2, RZ03-1C4-D005, RT314005) meet these primary and secondary criteria, confirming direct replacement capability with the ALZ11F05W.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified for direct replacement of the ALZ11F05W based on matching primary electrical and mechanical parameters. Selection among substitutes should be based on the following factors:

RZ03-1C4-D005 (TE Connectivity): Highest inventory availability (39,553 units) with ROHS3 compliance and REACH unaffected status. Operates at 8 ms response time versus 15 ms for the ALZ11F05W. Contact material is Silver Nickel (AgNi) rather than Silver Tin Oxide. Seal rating not specified in documentation.

5-1415899-2 (TE Connectivity): Moderate inventory (3,677 units) with ROHS3 compliance and REACH unaffected status. Maintains Silver Tin Oxide contact material matching the ALZ11F05W. Sealed flux protection rating confirmed. Operating temperature range limited to -40°C ~ 85°C versus -40°C ~ 105°C for the main part.

RT314005 (TE Connectivity): Lower inventory (1,400 units) with ROHS3 compliance and REACH unaffected status. Coil current specification (80.6 mA) closely matches the ALZ11F05W (80 mA). Sealed flux protection confirmed. Operating temperature range limited to -40°C ~ 85°C.

All substitutes carry active product status and meet regulatory requirements. Selection should account for application temperature requirements, contact material compatibility with load characteristics, and inventory lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can RZ03-1C4-D005 replace ALZ11F05W in all applications?

A: RZ03-1C4-D005 meets all primary electrical and mechanical matching criteria (5VDC coil, SPDT contact form, 16A rating, through-hole PC pin termination). However, the operating temperature range is limited to -40°C ~ 85°C compared to -40°C ~ 105°C for the ALZ11F05W. Applications requiring operation above 85°C require evaluation of thermal performance. Contact material differs (Silver Nickel versus Silver Tin Oxide), which may affect performance with specific load types.

Q: What is the difference between the contact materials used in these relays?

A: The ALZ11F05W and 5-1415899-2 use Silver Tin Oxide (AgSnO) contact material. RZ03-1C4-D005 and RT314005 use Silver Nickel (AgNi) contact material. Both materials are suitable for general purpose switching applications. Contact material selection affects wear characteristics, contact resistance, and suitability for specific load types. Consult application requirements before substituting based on contact material differences.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The ALZ11F05W is supplied in Bulk packaging, while all three substitute parts (5-1415899-2, RZ03-1C4-D005, RT314005) are supplied in Tube packaging. Tube packaging may require adjustment to receiving and storage procedures but does not affect electrical or mechanical compatibility.

Q: What are the timing differences between these relays?

A: The ALZ11F05W operates with 15 ms operate time and 5 ms release time. All three substitutes operate with 8 ms operate time and 6 ms release time. These differences may affect circuit timing in applications with strict switching speed requirements. Evaluate circuit performance before substitution in time-critical applications.

Q: Do all substitutes meet the same regulatory approvals as the ALZ11F05W?

A: The ALZ11F05W carries cURus and VDE approvals with RoHS Compliant status. All three substitutes carry ROHS3 Compliant status and REACH Unaffected status. Both compliance frameworks are current regulatory standards. Verify that ROHS3 compliance meets specific application or regional requirements.

Q: What is the maximum switching voltage for each relay?

A: The ALZ11F05W supports 440VAC maximum switching voltage. All three substitutes support 400VAC maximum switching voltage. Applications requiring switching above 400VAC require the ALZ11F05W or equivalent parts rated for higher voltages.
