ADJH22005 General Purpose Relay SPST 50A 5V

Part Overview

The ADJH22005 is a general purpose relay manufactured by Panasonic Electric Works, designed for SPST-NO (1 Form A) switching applications with a 5VDC coil. This through-hole mounted relay is rated for 50A contact current and 480VAC maximum switching voltage, making it suitable for industrial control and switching circuits. The part is currently active in production with 815 units in stock. Equivalent substitute parts may be required due to supply chain considerations, design revisions, or inventory availability.

Key Parameters

Substitute Part Grouping Explanation

The ADJH22005 has one parametric equivalent substitute: ADJH21005. This substitution is valid based on the following critical parameters that remain identical across both parts:

Coil voltage (5VDC), contact form (SPST-NO), contact rating (50A), switching voltage (480VAC maximum), load capacity (24000VA), coil current (200 mA), coil type (latching single coil), mounting type (through hole), termination style (PC pin), operating temperature range (-40°C to 85°C), contact material (Silver Tin Oxide), coil resistance (25 Ohms), operate and release times (20 ms each), must operate voltage (3.75 VDC), and seal rating (sealed with flux protection).

Both parts belong to the ADJH series and share identical electrical and mechanical specifications. The primary difference lies in the base product number designation (ADJH22 versus ADJH21) and RoHS compliance status variation.

Parameter Comparison

Engineering Selection Recommendations

Both ADJH22005 and ADJH21005 are active production parts from Panasonic Electric Works with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

The ADJH22005 carries RoHS Compliant certification, while the ADJH21005 carries ROHS3 Compliant certification. Both parts meet international regulatory requirements and carry cURus and VDE approvals. Inventory availability differs, with ADJH21005 currently showing 889 units in stock compared to 815 units for ADJH22005. For applications requiring specific RoHS compliance documentation, verify the applicable standard required by your regulatory framework or customer specifications.

Frequently Asked Questions (FAQ)

Q: Can ADJH21005 be used as a direct replacement for ADJH22005?

A: Yes. Both parts share identical electrical specifications including 5VDC coil voltage, 50A contact rating, 480VAC maximum switching voltage, SPST-NO contact form, and identical timing characteristics. Both are through-hole mounted with PC pin termination and operate within the same temperature range.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with Restriction of Hazardous Substances directives. ROHS3 represents a more recent iteration of the standard. For your specific application, confirm which standard is required by your design specifications or customer requirements.

Q: Are the physical dimensions and pin configurations identical?

A: Both parts share the same series designation (ADJH), mounting type (through hole), and termination style (PC pin). Physical compatibility is confirmed for PCB layout purposes.

Q: What is the coil resistance and operating current?

A: Both parts have a coil resistance of 25 Ohms with a coil current of 200 mA at 5VDC. The must operate voltage is 3.75 VDC for both parts.

Q: What contact material is used?

A: Both ADJH22005 and ADJH21005 use Silver Tin Oxide (AgSnO) contact material, providing consistent switching performance and reliability across equivalent parts.
