TE Connectivity 104427-3 Equivalent & Substitute Parts
Part Overview
The TE Connectivity 104427-3 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole connector features 5 positions at 0.100" (2.54mm) pitch with male pin contacts, unshrouded design, and press-fit/solder termination. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design and production requirements. Substitute parts maintain core electrical and mechanical compatibility while offering improved availability and compliance status.

Substitute Part Grouping Explanation
Substitution eligibility for rectangular connectors in the 5-position 2.54mm pitch category is determined by the following parameters: connector type (header/breakaway), contact type (male pin), number of positions (5), mating pitch (0.100"), mounting method (through hole), and current rating (minimum 3A). All substitute parts listed maintain these core electrical and mechanical specifications.
Substitute parts are grouped into two categories based on termination and contact post length variations:
Direct Substitutes (Identical Post Length): Parts with contact post length of 0.120" (3.05mm) provide direct mechanical and electrical interchange with the original 104427-3 without PCB redesign.
Extended Post Length Variants: Parts with contact post lengths of 0.220" (5.58mm), 0.320" (8.13mm), 0.420" (10.67mm), and 0.520" (13.21mm) accommodate applications requiring deeper PCB penetration or stacked connector configurations.
Contact Finish Variations: Substitute parts offer either gold-plated mating contacts (PBC05 series) or tin-plated mating contacts (PEC05 series), both meeting the electrical requirements of the original specification.

Engineering Selection Recommendations
For Direct Mechanical and Electrical Interchange:
The TE Connectivity 5-146288-5 provides the closest functional equivalent to the 104427-3, maintaining identical electrical specifications (3A current rating, -65°C to 105°C operating range) with a contact post length of 0.125" (3.18mm), which is within 0.005" of the original 0.120" specification. This part achieves RoHS compliance while retaining the same AMPMODU Mod II series design. The 5-146288-5 is classified as obsolete but remains available in inventory.
For Active Production Status with Enhanced Specifications:
The Sullins PBC05SFAN and PEC05SFAN connectors provide active product status with extended operating temperature range (-65°C to 125°C) and identical 0.120" (3.05mm) post length. Both parts maintain 3A current rating and UL94 V-0 flammability rating. The PBC05SFAN features gold-plated mating contacts matching the original specification, while the PEC05SFAN provides tin-plated mating contacts. Both achieve RoHS3 compliance.
For Applications Requiring Extended Post Length:
Sullins PBC05SFBN, PBC05SFCN, and PBC05SFDN provide post lengths of 0.220", 0.320", and 0.420" respectively, accommodating deeper PCB penetration or stacked connector configurations. All maintain 3A current rating, -65°C to 125°C operating range, and RoHS3 compliance with gold-plated mating contacts.
For Higher Current Capacity:
The Amphenol ICC 78511-405HLF (BERGSTIK® II series) provides 5A current rating with 0.120" post length, -65°C to 125°C operating range, and active product status. This part accommodates applications requiring increased current handling capacity while maintaining mechanical compatibility.
Frequently Asked Questions (FAQ)
Q: Can the 104427-3 be directly replaced with any of the listed substitutes without PCB modification?
A: The PBC05SFAN and PEC05SFAN connectors provide direct mechanical and electrical interchange with identical 0.120" (3.05mm) contact post length. The 5-146288-5 offers near-identical specifications with 0.125" post length, requiring minimal PCB adjustment if any. All other listed parts feature extended post lengths and require PCB redesign.
Q: What is the difference between PBC05 and PEC05 series connectors?
A: The primary difference is the mating contact finish. PBC05 series connectors feature gold-plated mating contacts, matching the original 104427-3 specification. PEC05 series connectors feature tin-plated mating contacts. Both series maintain identical electrical performance, current rating, and operating temperature range. Selection depends on application requirements and existing connector socket specifications.
Q: Are all substitute parts RoHS compliant?
A: The original 104427-3 is RoHS non-compliant. The TE Connectivity 5-146288-5 achieves RoHS compliance. All Sullins connectors (PBC05 and PEC05 series) and the Amphenol ICC 78511-405HLF achieve RoHS3 compliance. Compliance status should be verified against specific application and regional requirements.
Q: What determines the selection between different post length variants?
A: Contact post length is determined by PCB thickness and application requirements. The standard 0.120" length accommodates typical PCB thicknesses. Extended lengths (0.220", 0.320", 0.420", 0.520") are used for thicker PCBs, stacked connector applications, or designs requiring deeper solder joint penetration. PCB design specifications must be consulted to determine appropriate post length.
Q: Can the 78511-405HLF be used as a direct substitute despite higher current rating?
A: The 78511-405HLF maintains identical 0.120" post length and 5-position 2.54mm pitch configuration, enabling mechanical compatibility. The 5A current rating exceeds the original 3A specification, providing enhanced capacity for applications requiring higher current handling. However, the tin-plated mating contact finish differs from the original gold-plated specification, requiring verification of compatibility with existing mating connectors.
Q: What is the significance of the operating temperature range difference between 104427-3 and substitute parts?
A: The original 104427-3 operates from -65°C to 105°C. Most substitute parts extend the upper limit to 125°C, providing enhanced thermal performance for high-temperature applications. This extended range does not affect compatibility with applications operating within the original -65°C to 105°C specification.
Q: Are Sullins connectors electrically equivalent to TE Connectivity and Amphenol ICC parts?
A: Yes. All listed Sullins connectors maintain identical electrical specifications (3A current rating, 30VAC voltage rating where specified, UL94 V-0 flammability rating) and mechanical compatibility (5 positions, 0.100" pitch, through-hole mounting, push-pull fastening). Differences in contact material (phosphor bronze versus copper alloy) and contact finish do not affect electrical performance within the specified operating parameters.
