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

Part Overview

The PP-002D is a power barrel connector plug manufactured by CUI Devices, designed for free-hanging (in-line) solder applications. This connector features a 1.30mm ID (0.051") and 4.60mm OD (0.138") barrel configuration with a rated capacity of 24VDC at 5A. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PP-002D is determined by strict equivalence across the following critical parameters:

• Connector Type & Gender: Both must be plug-type, female gender connectors
• Mating Diameter Specifications: The barrel ID and OD dimensions must be compatible with existing mating receptacles
• Electrical Ratings: Voltage (24VDC) and current capacity (5A) must meet or exceed the original specification
• Contact Configuration: 2 conductors with 2 contacts required
• Termination Method: Solder termination capability required
• Mounting Configuration: Free-hanging (in-line) mounting type required
• Operating Temperature Range: Must support 0°C ~ 40°C minimum
• Compliance Standards: RoHS compliance status and REACH compliance required

The PP3-002D qualifies as a substitute based on these parameters, with the following dimensional variance: the PP3-002D features a 1.35mm ID (0.053") barrel diameter compared to the PP-002D's 1.30mm ID. This represents a 0.05mm increase in inner diameter. Compatibility depends on the mechanical tolerance of the mating receptacle in the target application.

Parameter Comparison

Engineering Selection Recommendations

The PP3-002D is an active product with current manufacturing support and enhanced compliance certification (ROHS3 vs. RoHS). Both parts maintain identical electrical ratings (24VDC, 5A) and operating temperature specifications (0°C ~ 40°C). Both are REACH Unaffected and feature equivalent contact materials and configurations.

The primary consideration for substitution is the barrel inner diameter variance: PP3-002D features a 1.35mm ID compared to PP-002D's 1.30mm ID, representing a 0.05mm increase. This dimensional difference must be evaluated against the mechanical tolerances of the mating receptacle in the target application. The PP3-002D's active product status and enhanced compliance profile support its use in new designs and legacy system replacements where receptacle compatibility permits.

Frequently Asked Questions (FAQ)

Q: Can the PP3-002D directly replace the PP-002D in all applications?

A: Substitution is contingent upon the mechanical tolerance of the mating receptacle. The PP3-002D has a 1.35mm ID barrel compared to the PP-002D's 1.30mm ID. If the receptacle is designed with tight tolerances for the 1.30mm specification, the larger 1.35mm plug may not achieve proper fit or electrical contact. Receptacle specifications must be verified before substitution.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both the PP-002D and PP3-002D are rated for 24VDC at 5A with identical contact materials (brass with nickel plating) and operating temperature ranges (0°C ~ 40°C).

Q: What is the difference in housing material between these connectors?

A: The PP-002D uses Polyvinyl Chloride (PVC) housing, while the PP3-002D uses Thermoplastic housing. Both materials provide adequate insulation and mechanical protection for the specified electrical ratings and operating conditions.

Q: Why is the PP-002D listed as obsolete?

A: The PP-002D is no longer in active production. The PP3-002D represents the current active equivalent from CUI Devices for this connector category and should be considered for new designs and component sourcing.

Q: Are both parts RoHS compliant?

A: Yes. The PP-002D is RoHS Compliant, and the PP3-002D is ROHS3 Compliant. Both meet regulatory requirements for hazardous substance restrictions. Both parts are REACH Unaffected.

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

A: The PP-002D has a mating length of 0.374" (9.50mm), while the PP3-002D has a mating length of 0.354" (9.00mm). This 0.02" difference may affect mechanical fit in space-constrained applications.
