Engineering Selection Recommendations
Primary Substitutes (TE Connectivity Z-PACK Series):
The TE Connectivity parts 5188733-1, 1-5188398-9, 5100143-1, 5106164-1, 5106413-1, 5188398-9, and 5188731-1 are direct functional equivalents to the obsolete 188733-1. All maintain identical electrical specifications (1.5A current rating, 500Vrms voltage rating) and mechanical configuration (110 positions, 2.00mm pitch, 5 rows, press-fit termination). These parts carry active product status and meet current RoHS compliance requirements, making them suitable for new designs and production continuity.
The 5188733-1 represents the most direct replacement, sharing the identical base product number with updated compliance status. Parts 5106164-1 and 5106413-1 include additional features (Alignment Strip and Board Guide) that enhance assembly precision without affecting electrical performance.
Secondary Substitutes (HARTING har-bus® HM Series):
The HARTING parts 17011101201, 17011102204, and 17011102402 provide cross-manufacturer alternatives meeting the same mechanical and thermal specifications. These connectors feature identical position count, pitch, row configuration, and press-fit termination. However, the HARTING series specifies a 1.0A current rating compared to the 1.5A rating of the TE Connectivity parts. Voltage rating specifications are not provided for HARTING parts. Selection of HARTING alternatives is appropriate only when circuit current requirements do not exceed 1.0A per contact.
All substitute parts listed carry ROHS3 compliance and REACH unaffected or vendor-undefined status, supporting regulatory requirements for modern applications.
Frequently Asked Questions (FAQ)
Q: Can the 188733-1 be directly replaced with 5188733-1?
A: Yes. The 5188733-1 is a direct functional equivalent with identical electrical and mechanical specifications. The primary difference is product status (active versus obsolete) and RoHS compliance (compliant versus non-compliant). The 5188733-1 is suitable for all applications previously using 188733-1.
Q: What is the difference between TE Connectivity Z-PACK substitutes?
A: All TE Connectivity Z-PACK substitutes (5188733-1, 1-5188398-9, 5100143-1, 5106164-1, 5106413-1, 5188398-9, 5188731-1) maintain identical electrical ratings and core mechanical specifications. Variations include optional features such as Alignment Strip (5106164-1) and Board Guide configurations. These features enhance assembly accuracy without affecting electrical performance or compatibility.
Q: Are HARTING har-bus® HM connectors fully compatible with the 188733-1?
A: HARTING connectors match the mechanical specifications (110 positions, 2.00mm pitch, 5 rows, press-fit termination, through-hole mounting) and operating temperature range. However, the HARTING series specifies 1.0A current rating versus 1.5A for the TE Connectivity 188733-1. HARTING parts are compatible only in applications where per-contact current does not exceed 1.0A. Voltage rating information is not provided for HARTING parts.
Q: What does "press-fit termination" mean for substitution purposes?
A: Press-fit termination indicates that connector contacts are inserted into plated through-holes on the PCB using mechanical pressure rather than solder. All substitute parts listed use identical press-fit termination technology, ensuring compatibility with existing PCB designs and assembly processes.
Q: Does RoHS compliance affect electrical performance?
A: RoHS compliance addresses material composition and does not alter electrical performance. The obsolete 188733-1 is RoHS non-compliant, while all active substitutes are RoHS compliant. For new designs and production, RoHS-compliant parts (5188733-1, 1-5188398-9, 5100143-1, 5106164-1, 5106413-1, 5188398-9, 5188731-1) are required to meet regulatory standards.
Q: Can I use a substitute part with lower current rating in a high-current application?
A: No. The HARTING har-bus® HM series (17011101201, 17011102204, 17011102402) specifies 1.0A current rating. These parts are not suitable for applications requiring the full 1.5A rating of the original 188733-1. Use TE Connectivity substitutes for applications requiring 1.5A per contact.
Q: What is the significance of "Board Guide" and "Alignment Strip" features?
A: Board Guide and Alignment Strip are mechanical features that improve connector alignment during assembly. These features do not affect electrical specifications or compatibility. Parts with these features (5106164-1, 5106413-1, 17011102204, 17011102402) provide enhanced assembly precision compared to parts without these features.
Q: Are all substitute parts available in the same packaging as the original 188733-1?
A: The original 188733-1 packaging is not specified in the provided data. All listed substitute parts are available in Tube packaging. Verify packaging requirements for your specific procurement and assembly processes.
Q: What is the contact finish specification for substitute parts?
A: The original 188733-1 specifies gold contact finish at 30.0µin (0.76µm) thickness. TE Connectivity substitutes maintain identical gold finish specifications. HARTING parts specify gold or gold-palladium finish without thickness specification. Both finishes are compatible with standard PCB through-hole plating.
