ADJH22012 General Purpose Relay SPST 50A 12VDC

Part Overview

The ADJH22012 is a general purpose relay manufactured by Panasonic Electric Works, designed for SPST-NO (1 Form A) switching applications at 12VDC coil voltage with 50A contact rating. This through-hole mounted relay is sealed for flux protection and operates across industrial temperature ranges from -40°C to 85°C. The part is currently active in production with 1035 units in stock. Equivalent substitute parts may be required due to supply chain constraints, inventory availability, or design revision cycles in manufacturing environments.

Key Parameters

Substitute Part Grouping Explanation

The ADJH22012 relay belongs to the Panasonic Electric Works ADJH series of general purpose relays. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Coil voltage: 12VDC
• Contact form: SPST-NO (1 Form A)
• Contact rating: 50 A
• Switching voltage: 480VAC maximum
• Maximum switching load: 24000VA
• Mounting type: Through hole
• Termination style: PC pin
• Operating temperature range: -40°C to 85°C
• Contact material: Silver Tin Oxide (AgSnO)
• Seal rating: Sealed - flux protection
• Coil insulation class: Class F
• Approval agencies: cURus, VDE

The ADJH21012 meets all these criteria and is classified as a parametric equivalent within the ADJH series.

Parameter Comparison

Engineering Selection Recommendations

Both ADJH22012 and ADJH21012 are active production parts from Panasonic Electric Works with identical electrical and mechanical specifications. Both parts carry cURus and VDE approvals and comply with RoHS requirements. The ADJH21012 carries ROHS3 compliance designation, indicating alignment with the most current RoHS directive revision. Both parts maintain MSL Level 1 (unlimited moisture sensitivity) and share identical ECCN and HTSUS classifications for export and tariff purposes.

Selection between these parts should be based on inventory availability and compliance requirements specific to the end application. The ADJH22012 currently has higher inventory availability at 1035 units compared to 925 units for the ADJH21012.

Frequently Asked Questions (FAQ)

Q: Can ADJH21012 be used as a direct replacement for ADJH22012?

A: Yes. Both parts are parametric equivalents within the ADJH series with identical electrical ratings, contact specifications, coil characteristics, and operating parameters. They share the same through-hole PC pin termination and sealed flux protection design.

Q: Are there differences in compliance certifications between these parts?

A: Both parts carry cURus and VDE approvals. The ADJH21012 specifies ROHS3 compliance while the ADJH22012 specifies RoHS compliance. Both meet RoHS requirements and carry identical ECCN and HTSUS classifications.

Q: Do these relays have identical switching performance?

A: Yes. Both parts have identical operate time (20 ms), release time (20 ms), must operate voltage (9 VDC), coil current (83.3 mA), and coil resistance (144 Ohms). They handle identical maximum switching loads of 24000VA at 480VAC.

Q: Are the packaging and mounting specifications the same?

A: Yes. Both parts are supplied in trays with through-hole mounting and PC pin termination. They are designed for identical PCB footprints and assembly processes.

Q: What is the difference between the base product numbers ADJH22 and ADJH21?

A: The base product numbers indicate different design revisions within the ADJH series. However, the ADJH22012 and ADJH21012 variants are parametric equivalents with no functional differences in electrical or mechanical performance.
