ALZ12B06 Equivalent & Substitute Parts

Part Overview

The ALZ12B06 is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 6VDC coil. This through-hole mounted relay is designed for applications requiring 16A switching capacity at up to 440VAC. The part is currently active in production and widely used in industrial control, automation, and switching applications where reliable electromechanical switching is required.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility allows for alternative manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ALZ12B06 is determined by strict equivalence across the following critical parameters:

• Coil Voltage: 6VDC (exact match required)
• Contact Form: SPDT (1 Form C) configuration
• Contact Rating: 16A minimum
• Coil Current: 66.7 mA (exact match required)
• Coil Resistance: 90 Ohms (exact match required)
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Operating Temperature Range: -40°C ~ 85°C minimum
• Must Operate Voltage: 4.2 VDC (exact match required)
• Must Release Voltage: 0.6 VDC (exact match required)

All three substitute parts (2-1415899-0, RT314006, and RTD14006) meet these critical parameters. Variations in switching voltage maximum (400VAC vs. 440VAC), contact material composition, seal rating, and coil insulation class do not preclude substitution when the application requirements fall within the lower specification limits.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified for direct replacement of the ALZ12B06 based on electrical and mechanical parameter equivalence. Selection among substitutes should be based on the following factors:

RT314006 and RTD14006 are preferred substitutes due to their tube packaging, which matches the original ALZ12B06 packaging format and facilitates inventory management consistency. Both parts carry ROHS3 compliance and REACH Unaffected status.

2-1415899-0 is functionally equivalent but supplied in bulk packaging. This part is suitable for applications where packaging format is not a constraint and bulk quantities are acceptable for manufacturing workflows.

All substitute parts operate within the same temperature range (-40°C ~ 85°C) and maintain identical coil voltage, current, and resistance specifications. The TE Connectivity substitutes feature faster operate times (8 ms vs. 15 ms) and marginally longer release times (6 ms vs. 5 ms), which may be advantageous in applications requiring rapid switching response.

The reduced maximum switching voltage specification (400VAC vs. 440VAC) on substitute parts does not impact compatibility for applications operating at or below 400VAC. Applications requiring the full 440VAC switching capability should retain the ALZ12B06.

Frequently Asked Questions (FAQ)

Q: Can RT314006 be used as a direct replacement for ALZ12B06 in existing designs?

A: Yes. RT314006 meets all critical electrical parameters including 6VDC coil voltage, 16A contact rating, 90 Ohm coil resistance, and identical must-operate and must-release voltage thresholds. Through-hole mounting and PC pin termination are identical. Tube packaging matches the original format.

Q: What is the difference between the three substitute parts?

A: The primary differences are packaging format and seal rating. RT314006 features flux protection sealing, while RTD14006 is fully sealed. 2-1415899-0 is supplied in bulk packaging without specified seal rating. All three are electrically and mechanically equivalent for the ALZ12B06 application.

Q: Are there switching speed differences between ALZ12B06 and the substitutes?

A: Yes. The ALZ12B06 operates in 15 ms with 5 ms release time. All TE Connectivity substitutes operate in 8 ms with 6 ms release time. For applications with strict timing requirements, this difference must be evaluated against circuit design specifications.

Q: Is the lower maximum switching voltage (400VAC vs. 440VAC) on substitutes a concern?

A: No, provided the application operates at or below 400VAC. If the design requires the full 440VAC switching capability, the ALZ12B06 must be retained. For standard industrial applications operating at 230VAC or 380VAC, the 400VAC specification is sufficient.

Q: Do all parts meet RoHS compliance requirements?

A: Yes. ALZ12B06 is RoHS Compliant. All three substitutes carry ROHS3 Compliant certification, which represents the current RoHS standard. All parts are suitable for RoHS-regulated applications.

Q: Which substitute should be selected for new designs?

A: RT314006 or RTD14006 are recommended for new designs due to tube packaging consistency with the original part and superior seal ratings. Selection between these two depends on whether flux protection or full sealing is required by the application environment.
