PJ-030D-SMT Equivalent & Substitute Parts

Part Overview

The PJ-030D-SMT is a power barrel connector jack manufactured by CUI Devices, designed for surface mount applications with a 1.30mm ID (0.051") and 4.60mm OD (0.138") mating diameter. This connector features a single normally closed internal switch, solder termination, and shielded construction suitable for low-voltage DC power applications. The part is currently obsolete, making identification of compatible substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PJ-030D-SMT is determined by strict equivalence in the following critical parameters:

• Mating Diameter Compatibility: The 1.30mm ID mating diameter is the primary mechanical interface criterion. Substitute parts must maintain this ID specification to ensure proper mating with corresponding plug connectors.
• Connector Configuration: Jack type with male gender, single normally closed internal switch, and shielded construction must be preserved.
• Mounting and Termination: Surface mount, right angle orientation with solder termination are required for PCB integration compatibility.
• Electrical Ratings: Voltage and current ratings of substitute parts must meet or exceed the original specification to ensure safe operation in the target application.
• Material and Compliance: Housing material (Polyamide PA6T), contact material (Brass/Copper with Silver plating), and regulatory compliance (UL94 V-0, RoHS) establish the baseline for functional equivalence.

The PJ-030DH-SMT-TR qualifies as a direct substitute based on these parameters, with the distinction that it is an active product with enhanced electrical ratings and improved availability.

Engineering Selection Recommendations

The PJ-030DH-SMT-TR is the direct substitute for the obsolete PJ-030D-SMT. Selection is based on the following engineering criteria:

• Functional Equivalence: Both parts share identical connector type, mating diameter (1.30mm ID), mounting configuration, and internal switch design, ensuring mechanical and electrical compatibility with existing mating connectors and PCB layouts.
• Enhanced Electrical Performance: The PJ-030DH-SMT-TR provides higher voltage (24VDC vs. 16VDC) and current (4.6A vs. 2A) ratings, making it suitable for applications requiring the original specifications and those with higher power demands within the same form factor.
• Active Product Status: The PJ-030DH-SMT-TR is an active product with established supply chain availability, eliminating obsolescence risk associated with the PJ-030D-SMT.
• Regulatory Compliance: Both parts meet UL94 V-0 flammability requirements and RoHS standards. The substitute carries ROHS3 compliance, reflecting current regulatory alignment.
• Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, standard for automated assembly processes, whereas the original was supplied in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the PJ-030DH-SMT-TR be used as a direct replacement for the PJ-030D-SMT in existing designs?

A: Yes. Both connectors share the same 1.30mm ID mating diameter, jack configuration, normally closed internal switch, and surface mount right angle termination. The substitute is mechanically and electrically compatible with existing mating plugs and PCB footprints. The enhanced electrical ratings of the substitute do not create compatibility issues in applications designed for the original part.

Q: What is the difference in outer diameter between these two parts?

A: The PJ-030D-SMT has a 4.60mm OD (0.138"), while the PJ-030DH-SMT-TR has a 3.40mm OD (0.134"). This 0.10mm difference does not affect mechanical compatibility or mating performance, as the critical mating interface is the 1.30mm ID, which is identical in both parts.

Q: Are there any voltage or current limitations when using the PJ-030DH-SMT-TR in place of the PJ-030D-SMT?

A: No. The substitute part has higher electrical ratings (24VDC, 4.6A) compared to the original (16VDC, 2A). Applications designed for the original specifications will operate safely within the substitute's rated parameters. If your application requires the original 16VDC/2A ratings, the substitute remains fully compatible and suitable.

Q: What packaging format does the substitute come in?

A: The PJ-030DH-SMT-TR is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly. The original PJ-030D-SMT was supplied in bulk packaging. Tape & Reel packaging is compatible with standard pick-and-place equipment used in modern PCB manufacturing.

Q: Are both parts RoHS compliant?

A: Yes. The PJ-030D-SMT is RoHS Compliant, and the PJ-030DH-SMT-TR is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions. ROHS3 represents the current regulatory standard and reflects the substitute's alignment with ongoing compliance requirements.
