PJ-005A Equivalent & Substitute Parts

Part Overview

The PJ-005A is a power barrel connector jack manufactured by CUI Devices, designed for panel mount through-hole applications. This 2.0mm ID × 5.5mm OD connector features a single normally closed switch, rated for 24VDC at 5A, and is suitable for low-voltage DC power distribution applications. The part is currently active in production with robust inventory availability. Substitute parts may be required due to supply constraints, design revisions, or application-specific requirements that demand alternative form factors or electrical ratings.

Substitute Part Grouping Explanation

The substitute part 722A (Hammond Manufacturing) is listed in the original part data. However, a critical incompatibility exists: 722A is a laminated core power transformer rated for 625VA with primary voltages of 117V/234V and secondary output of 1250V. This part operates in a fundamentally different functional category (transformers vs. connectors) and does not share electrical or mechanical compatibility parameters with the PJ-005A barrel connector jack.

Substitution logic for barrel connector jacks is determined by:

• Mating diameter (2.0mm ID × 5.5mm OD)
• Contact count and configuration (2 conductors, 3 contacts)
• Voltage and current ratings (24VDC, 5A minimum)
• Mounting method (panel mount, through-hole)
• Termination style (solder eyelet)
• Internal switch configuration (normally closed)

The 722A does not meet any of these criteria and cannot serve as a functional substitute for the PJ-005A.

Engineering Selection Recommendations

Based on the provided data, the 722A cannot be recommended as a substitute for the PJ-005A. The parts serve entirely different functions within electronic systems: the PJ-005A is a low-voltage DC power connector, while the 722A is a high-voltage AC power transformer. Selection of the PJ-005A should proceed based on its active product status, ROHS3 compliance, and established inventory availability. If supply constraints require alternative barrel connector jacks, substitutes must be sourced from the connector category with matching mating diameters (2.0mm ID × 5.5mm OD), contact configurations, and voltage/current ratings.

Frequently Asked Questions (FAQ)

Q: Can the 722A transformer replace the PJ-005A connector? A: No. The 722A is a power transformer designed for AC voltage conversion, while the PJ-005A is a DC power connector jack. These components serve different circuit functions and are not interchangeable.

Q: What parameters must a substitute barrel connector match? A: A valid substitute must maintain the 2.0mm ID × 5.5mm OD mating diameter, support 24VDC at 5A minimum, include 2 conductors with 3 contacts, feature a normally closed internal switch, and use solder eyelet termination for panel mount through-hole installation.

Q: Is the PJ-005A compliant with current regulations? A: Yes. The PJ-005A is ROHS3 compliant, REACH unaffected, and carries an MSL rating of 1 (unlimited moisture sensitivity level), indicating no special storage requirements.

Q: What is the operating temperature range for the PJ-005A? A: The PJ-005A operates reliably between -40°C and 70°C, suitable for industrial and consumer applications within this thermal envelope.

Q: How many contacts does the PJ-005A provide? A: The PJ-005A provides 3 contacts configured for 2 conductors, with a single normally closed internal switch for power detection or switching applications.
