PJ-016 Equivalent & Substitute Parts

Part Overview

The PJ-016 is a power barrel connector jack manufactured by CUI Devices, featuring a 1.70mm ID / 4.00mm OD EIAJ-2 form factor with kinked pin termination and through-hole, right-angle mounting. This connector is rated for 12VDC at 1A and includes a normally closed internal switch with board guide features.

The PJ-016 is classified as obsolete. Identifying suitable substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PJ-016 is determined by the following critical parameters:

• Mating Diameter Compatibility: All substitute parts must maintain the 1.70mm ID / 4.00mm OD EIAJ-2 industry standard to ensure mechanical and electrical mating with existing connector plugs.
• Mounting Configuration: Through-hole, right-angle mounting is required to maintain PCB layout compatibility.
• Internal Switch Function: Single switch, normally closed configuration must be preserved for circuit continuity requirements.
• Voltage and Current Ratings: Substitute parts must meet or exceed the 12VDC / 1A electrical requirements of the original design.
• Contact Configuration: 3-contact configuration with 2 conductors is the baseline requirement.
• Regulatory Compliance: All substitutes must maintain ROHS3 compliance and equivalent flammability ratings (UL94 V-0).

The three substitute parts (PJ-054, PJ-073, PJ-086H) share the core EIAJ-2 form factor and through-hole right-angle mounting with the PJ-016. Variations in termination type, shielding, housing material, and electrical ratings create distinct substitution scenarios based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

PJ-054 Substitution: The PJ-054 maintains identical mating diameter, mounting configuration, and contact count as the PJ-016. It offers higher voltage (24VDC) and current (2.5A) ratings with solder termination instead of kinked pin. The PJ-054 is active product status with ROHS3 compliance and UL94 V-0 flammability rating. Selection of PJ-054 requires PCB redesign to accommodate solder termination and acceptance of tin plating versus silver plating on contacts.

PJ-073 Substitution: The PJ-073 provides the closest functional equivalence to the PJ-016, maintaining kinked pin termination, silver contact plating, and PBT housing material. It offers higher voltage (24VDC) and current (2.5A) ratings with shielded construction. The PJ-073 is active product status with ROHS3 compliance and UL94 V-0 flammability rating. The addition of shielding and higher electrical ratings makes PJ-073 suitable for designs requiring electromagnetic interference mitigation.

PJ-086H Substitution: The PJ-086H features increased contact count (4 contacts, 3 conductors) and the highest current rating (5A) among substitutes. It includes shielded construction and solder termination with silver contact plating. The PJ-086H is active product status with ROHS3 compliance and UL94 V-0 flammability rating. Selection of PJ-086H requires PCB redesign to accommodate the additional contact and solder termination, and acceptance of Nylon 10T housing material.

All three substitute parts maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory equivalence to the obsolete PJ-016.

Frequently Asked Questions (FAQ)

Q: Can PJ-054 be used as a direct replacement for PJ-016 without PCB modification?

A: No. While PJ-054 maintains the same mating diameter and mounting configuration, it uses solder termination instead of kinked pin. PCB pad layout and hole sizing must be redesigned to accommodate solder termination. Additionally, contact plating differs (tin versus silver).

Q: What is the primary advantage of selecting PJ-073 over PJ-054?

A: PJ-073 retains kinked pin termination and silver contact plating identical to PJ-016, minimizing PCB redesign requirements. PJ-073 adds shielded construction and supports higher electrical ratings (24VDC, 2.5A). If PCB layout permits kinked pin mounting, PJ-073 offers the lowest redesign burden.

Q: Is PJ-086H compatible with existing PJ-016 connector plugs?

A: PJ-086H maintains the 1.70mm ID / 4.00mm OD mating diameter standard, ensuring mechanical compatibility with EIAJ-2 connector plugs. However, PJ-086H includes an additional contact (4 contacts versus 3), requiring plug redesign if the extra conductor is not utilized.

Q: What temperature range difference exists between PJ-016 and the substitute parts?

A: PJ-016 operates from -20°C to 85°C. All three substitute parts (PJ-054, PJ-073, PJ-086H) operate from -25°C to 85°C, providing extended low-temperature performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PJ-054, PJ-073, and PJ-086H are all ROHS3 compliant with UL94 V-0 flammability ratings, maintaining regulatory equivalence to the obsolete PJ-016.

Q: Which substitute part requires the least PCB redesign?

A: PJ-073 requires minimal redesign because it retains kinked pin termination, silver contact plating, and PBT housing material matching the PJ-016. Only the shielded construction and higher electrical ratings differ from the original design.

Q: What is the current rating difference between PJ-016 and PJ-086H?

A: PJ-016 is rated for 1A at 12VDC. PJ-086H is rated for 5A at 24VDC, providing significantly higher current capacity for power delivery applications.
