AZ8462-9 Equivalent & Substitute Parts Reference

Part Overview

The AZ8462-9 is a general purpose relay manufactured by American Zettler, featuring a DPDT (2 Form C) contact configuration with a 9VDC coil. This through-hole mounted relay is designed for applications requiring 2A switching capacity at voltages up to 250VAC or 220VDC. The part is currently active in production with 927 pieces in stock inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across critical operating parameters. The TX2-9V from Panasonic Electric Works represents a functionally compatible alternative, though classified as a telecom relay variant rather than general purpose.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AZ8462-9 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Coil voltage: 9VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 2 A minimum
• Switching voltage: 220VDC minimum (AZ8462-9 supports 250VAC/220VDC maximum)
• Coil current: 15.5 mA
• Coil resistance: 579 Ohms
• Must operate voltage: 6.75 VDC
• Must release voltage: 0.9 VDC
• Operate/release time: 4 ms each

Mechanical Parameters (Must Match Exactly):

• Mounting type: Through Hole
• Termination style: PC Pin
• Seal rating: Sealed - Fully

Environmental Parameters (Must Match or Exceed):

• Operating temperature range: -40°C ~ 85°C
• Coil type: Non Latching

Compliance Parameters:

• RoHS3 Compliant status required

The TX2-9V from Panasonic Electric Works meets all critical electrical, mechanical, environmental, and compliance requirements. The primary distinction is functional classification (telecom relay versus general purpose relay) and contact material composition, which do not affect substitution eligibility within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

AZ8462-9 Selection Criteria:

• Primary choice when general purpose relay classification is specified in design documentation
• Active product status with established supply chain (927 pieces in stock)
• ROHS3 compliant for regulatory requirements
• Supports full switching voltage range of 250VAC and 220VDC

TX2-9V Selection Criteria:

• Functionally equivalent substitute when AZ8462-9 availability is constrained
• Active product status with higher inventory availability (2315 pieces in stock)
• ROHS3 compliant with additional certifications: REACH Unaffected, ECCN EAR99, HTSUS 8536.41.0020
• Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) provides extended shelf life
• Switching voltage specification of 220VDC maximum requires verification for applications requiring 250VAC operation
• Telecom relay classification does not affect electrical performance within specified parameters

Packaging Consideration:

• AZ8462-9 supplied in Box packaging
• TX2-9V supplied in Tube packaging
• Packaging difference does not affect component functionality or PCB integration

Both parts maintain identical electrical performance across all critical operating parameters and environmental specifications within the stated ranges.

Frequently Asked Questions (FAQ)

Q: Can TX2-9V replace AZ8462-9 in all applications?

A: TX2-9V meets all critical electrical, mechanical, and environmental parameters specified for AZ8462-9. The primary consideration is switching voltage: AZ8462-9 supports 250VAC/220VDC maximum, while TX2-9V supports 220VDC maximum. For applications requiring 250VAC switching, AZ8462-9 is the specified part. For applications operating at 220VDC or lower, TX2-9V is functionally equivalent.

Q: What is the difference between "General Purpose" and "Telecom" relay classifications?

A: Classification reflects intended application category and design optimization. Both AZ8462-9 (General Purpose) and TX2-9V (Telecom) share identical electrical specifications, contact configuration, coil parameters, and operating characteristics. The classification difference does not affect substitution eligibility within the specified parameter constraints.

Q: Are the contact materials interchangeable?

A: AZ8462-9 specifies Silver Nickel (AgNi) and Gold (Au) contact material. TX2-9V specifies Silver (Ag) and Gold (Au). Both compositions support the 2A contact rating and 220VDC switching voltage. Contact material difference does not prevent substitution within the specified electrical operating range.

Q: Does packaging affect component selection?

A: Packaging format (Box for AZ8462-9, Tube for TX2-9V) affects logistics, storage, and handling procedures but does not affect electrical performance, PCB mounting, or functional operation. Component selection should be based on electrical and mechanical parameters, with packaging chosen according to procurement and assembly requirements.

Q: What is the significance of the TX2-9V MSL rating of 1 (Unlimited)?

A: Moisture Sensitivity Level (MSL) 1 indicates the component has unlimited shelf life without moisture control measures. This provides extended storage flexibility compared to components with higher MSL ratings, but does not affect electrical performance or substitution eligibility.

Q: Can I use AZ8462-9 where TX2-9V is specified?

A: Yes. AZ8462-9 meets or exceeds all electrical and mechanical parameters of TX2-9V. The higher switching voltage capability (250VAC/220VDC versus 220VDC) of AZ8462-9 provides additional operational margin. Substitution in the reverse direction is valid.

Q: Are both parts currently in production?

A: Yes. Both AZ8462-9 and TX2-9V maintain Active product status. AZ8462-9 has 927 pieces in stock inventory. TX2-9V has 2315 pieces in stock inventory, providing higher availability for immediate procurement.
