PJ-022-SMT Equivalent & Substitute Parts

Part Overview

The PJ-022-SMT is a power barrel connector jack manufactured by CUI Devices, designed for surface mount applications with 0.70mm ID (0.028"), 2.35mm OD (0.093") EIAJ-1 mating dimensions. This connector features a single normally closed internal switch, solder termination, and right-angle mounting configuration. The part is currently listed as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The PJ1-022-SMT-TR qualifies as a direct substitute for the PJ-022-SMT based on the following critical parameters:

Matching Parameters:

• Connector type (Jack), gender (Male), and mating diameter (0.70mm ID, 2.35mm OD EIAJ-1)
• Mounting configuration (Surface Mount, Right Angle)
• Termination method (Solder)
• Contact configuration (2 Conductors, 3 Contacts)
• Internal switch function (Single Switch, Normally Closed)
• Current rating (2.5 A)
• Operating temperature range (-25°C ~ 85°C)
• Housing and contact materials (Polyamide PA6T, Brass/Copper Alloy with Silver plating)
• Flammability rating (UL94 V-0)

Allowable Variation:

• Voltage rating: PJ1-022-SMT-TR is rated for 24VDC compared to PJ-022-SMT at 16VDC. The higher voltage rating of the substitute part is compatible with applications requiring 16VDC operation.
• Actual diameter tolerance: Minor dimensional variation (0.026" to 0.110" OD range) remains within acceptable mechanical compatibility for EIAJ-1 standard mating.
• Packaging: PJ1-022-SMT-TR is supplied in Tape & Reel format versus bulk packaging of the obsolete part.

Parameter Comparison

Engineering Selection Recommendations

The PJ1-022-SMT-TR is the appropriate substitute for the obsolete PJ-022-SMT. Selection is based on the following engineering criteria:

Product Status: The PJ-022-SMT is obsolete with limited remaining inventory (746 pieces). The PJ1-022-SMT-TR is an active product with substantial inventory availability (24,498 pieces), ensuring long-term supply chain continuity.

Electrical Compatibility: The substitute part's 24VDC rating exceeds the original 16VDC specification, providing enhanced voltage margin for applications operating at or below 16VDC. Current rating, contact configuration, and internal switch function are identical.

Mechanical Compatibility: Both parts conform to the EIAJ-1 standard for 0.70mm ID, 2.35mm OD barrel connectors with identical mounting configuration, termination method, and mating depth. Minor actual diameter variations remain within acceptable mechanical tolerance for connector mating.

Compliance and Certification: The PJ1-022-SMT-TR carries ROHS3 compliance certification, whereas the obsolete part lists compliance as not applicable. Both parts maintain UL94 V-0 flammability rating and identical operating temperature specifications.

Packaging Consideration: The substitute is supplied in Tape & Reel format, standard for active production components and compatible with automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PJ1-022-SMT-TR be used as a direct replacement for PJ-022-SMT in existing designs?

A: Yes. The PJ1-022-SMT-TR is electrically and mechanically compatible with the PJ-022-SMT. Both parts share identical connector type, mating diameter (EIAJ-1 0.70mm ID, 2.35mm OD), mounting configuration, termination method, contact count, and internal switch function. The substitute's higher voltage rating (24VDC vs. 16VDC) is compatible with 16VDC applications.

Q: What is the significance of the voltage rating difference between the two parts?

A: The PJ1-022-SMT-TR is rated for 24VDC while the PJ-022-SMT is rated for 16VDC. A higher voltage rating indicates the substitute part can safely operate at higher voltages without degradation. Applications operating at 16VDC or lower are fully compatible with the 24VDC-rated substitute.

Q: Are there any mechanical compatibility concerns due to actual diameter variations?

A: No. The actual diameter measurements (0.026" ID, 0.108"-0.110" OD) for both parts fall within acceptable tolerance ranges for EIAJ-1 standard barrel connectors. These minor variations do not affect mating compatibility or connector performance.

Q: What is the difference between the bulk packaging of PJ-022-SMT and the Tape & Reel packaging of PJ1-022-SMT-TR?

A: Tape & Reel (TR) packaging is the standard format for active production components and is optimized for automated assembly processes. Bulk packaging was used for the obsolete part. Both packaging formats contain the same connector; the difference is in presentation and handling method during assembly.

Q: Does the ROHS3 compliance of PJ1-022-SMT-TR affect compatibility with existing designs?

A: No. ROHS3 compliance indicates the substitute part meets current environmental and material restriction standards. This certification does not affect electrical or mechanical compatibility and is beneficial for regulatory compliance in modern applications.

Q: Are both parts manufactured by the same company?

A: Yes. Both PJ-022-SMT and PJ1-022-SMT-TR are manufactured by CUI Devices, ensuring consistent design standards and quality control.
