PP-002A Power Barrel Connector Plug Equivalent & Substitute Parts

Part Overview

The PP-002A is a power barrel connector plug manufactured by CUI Devices, designed for free-hanging (in-line) solder applications. This connector features a 2.00mm ID and 5.50mm OD configuration with 2 conductors and 2 contacts, rated for 24VDC at 5A operation across a temperature range of 0°C to 40°C. The product is currently classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PP-002A is determined by the following critical parameters:

Mechanical Compatibility: Connector type (plug), gender (female), mounting configuration (free hanging in-line), and housing material (POM) must remain consistent.

Electrical Compatibility: Voltage and current ratings must meet or exceed the original specification. The PP-002A operates at 24VDC with 5A capacity.

Dimensional Compatibility: The mating diameter (ID/OD) and contact configuration (2 conductors, 2 contacts) define the physical interface. Variations in these dimensions affect mating compatibility with corresponding jack connectors.

Termination Method: Solder termination is required for direct replacement in existing PCB layouts.

Regulatory Compliance: RoHS and REACH status are evaluated for system-level compliance requirements.

The PP3-002A qualifies as a substitute based on shared connector type, gender, mounting method, housing material, contact configuration, and termination approach. However, dimensional differences in the mating diameter (2.10mm ID versus 2.00mm ID) and electrical ratings (20VDC, 6A versus 24VDC, 5A) must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The PP3-002A is an active product with RoHS3 compliance, addressing the obsolescence status of the PP-002A. Both connectors share identical outer diameter (5.50mm OD), contact configuration (2 conductors, 2 contacts), mounting method (free hanging in-line), and housing material (POM).

The primary technical difference is the inner diameter: PP3-002A features a 2.10mm ID compared to the PP-002A's 2.00mm ID. This dimensional variance affects mating compatibility with corresponding jack connectors. Systems designed for 2.00mm ID jacks will not mate with 2.10mm ID plugs.

Electrical rating differences exist: PP-002A is rated 24VDC at 5A, while PP3-002A is rated 20VDC at 6A. Applications operating at 24VDC exceed the PP3-002A voltage specification and require alternative solutions or system redesign.

For applications operating at 20VDC or below with 6A or less current demand, and where the mating jack connector accommodates 2.10mm ID plugs, the PP3-002A provides an active, RoHS3-compliant alternative to the obsolete PP-002A.

Frequently Asked Questions (FAQ)

Q: Can the PP3-002A directly replace the PP-002A in existing assemblies?

A: Direct replacement depends on two factors: (1) the mating jack connector must accept a 2.10mm ID plug (PP-002A uses 2.00mm ID), and (2) the application voltage must not exceed 20VDC (PP-002A is rated 24VDC). If either condition is not met, the PP3-002A is not a direct substitute.

Q: What is the significance of the inner diameter difference between 2.00mm and 2.10mm?

A: The inner diameter determines the physical fit between the plug and jack connector. A 2.10mm ID plug will not mate with a 2.00mm ID jack. Conversely, a 2.00mm ID plug will not mate with a 2.10mm ID jack. Mating compatibility requires matching diameters.

Q: Why is the PP-002A classified as obsolete?

A: The PP-002A is no longer in active production. The PP3-002A represents the current active product line from CUI Devices for this connector category, offering improved regulatory compliance (RoHS3) and higher current capacity (6A).

Q: Does the PP3-002A meet RoHS requirements?

A: Yes, the PP3-002A is RoHS3 compliant. The PP-002A is RoHS non-compliant. For systems requiring RoHS compliance, the PP3-002A is the appropriate choice, provided electrical and dimensional requirements are satisfied.

Q: Are there packaging differences between these parts?

A: The PP-002A packaging is not specified in the available data. The PP3-002A is supplied in bag packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: What is the mating length difference between these connectors?

A: The PP-002A has a mating length of 0.551" (14.00mm), while the PP3-002A has a mating length of 0.374" (9.50mm). This difference may affect mechanical fit in space-constrained applications.
