TE Connectivity 5188731-1 Equivalent & Substitute Parts
Part Overview
The TE Connectivity 5188731-1 is a 110-position header connector with male pins, designed for backplane applications using 2.00mm (0.079") pitch press-fit termination. This connector features through-hole mounting with a 5-row configuration and gold-plated contacts rated for 1.5A at 500Vrms across an operating temperature range of -55°C to 125°C. The part is currently active in production and RoHS compliant.
Substitute parts are identified based on matching electrical and mechanical specifications including connector position count, pitch, mounting type, termination method, and operating parameters. Alternative sources provide equivalent functionality for applications requiring backplane header connectors with identical or superior electrical ratings.

Substitute Part Grouping Explanation
Substitute parts are classified into two categories based on electrical and mechanical compatibility with the TE Connectivity 5188731-1:
Category 1: Direct Electrical Equivalents (110-Position, 5-Row Configuration)
These parts maintain identical position count, pitch, row configuration, and mounting type. Substitution is based on matching the following critical parameters:
- Number of Positions: 110
- Pitch: 0.079" (2.00mm)
- Number of Rows: 5
- Mounting Type: Through Hole
- Termination: Press-Fit
- Connector Style: A 22
- Operating Temperature: -55°C to 125°C
Parts in this category include HARTING 17011101201 and 17011102204, and Amphenol ICC (FCI) Millipacs® series parts HM2P07PA5110AALF, HM2P07PD5110N9LF, HM2P07PD51M0N9LF, and HM2P07PDE120N9LF.
Category 2: Extended Position Configurations (154-Position, 5+2 Row Configuration)
These parts provide increased position count (154 positions with 110 signal + 44 ground) while maintaining the same 2.00mm pitch and press-fit termination. These are suitable for applications requiring additional grounding capability. Parts include Amphenol ICC (FCI) HM2P07PA5111AALF and HM2P07PD5111N9LF.
Category 3: Accessory Components (Shroud)
The Amphenol ICC (FCI) HM2H07P115LF is a shroud component for 110-position hard metric connectors. This part is not a direct substitute but a complementary accessory for connector protection and alignment.

Engineering Selection Recommendations
For Direct Substitution (110-Position, 5-Row Configuration):
The Amphenol ICC (FCI) Millipacs® series parts HM2P07PA5110AALF, HM2P07PD5110N9LF, HM2P07PD51M0N9LF, and HM2P07PDE120N9LF are functionally equivalent to the TE Connectivity 5188731-1. These parts maintain identical position count, pitch, row configuration, and current rating. All are active products with RoHS compliance. The Amphenol parts feature higher voltage ratings (750Vrms versus 500Vrms), providing superior electrical performance in equivalent form factors.
The HARTING har-bus® HM series parts 17011101201 and 17011102204 are mechanically compatible alternatives with identical position count, pitch, and row configuration. Both are active products with ROHS3 compliance. The HARTING parts are rated for 1.0A current, which is lower than the TE Connectivity specification of 1.5A. Part 17011102204 includes board guide features matching the TE Connectivity design.
For Extended Grounding Applications (154-Position, 5+2 Row Configuration):
The Amphenol ICC (FCI) parts HM2P07PA5111AALF and HM2P07PD5111N9LF provide 154-position configurations with integrated ground planes (110 signal + 44 ground positions). These parts maintain the same 2.00mm pitch and press-fit termination while offering enhanced grounding capability. Both are active products with RoHS compliance and 750Vrms voltage ratings.
For Accessory Components:
The Amphenol ICC (FCI) HM2H07P115LF shroud is an obsolete product and is not recommended for new designs. This part is listed for reference only in applications requiring connector protection and alignment.
Frequently Asked Questions (FAQ)
Q: Can HARTING 17011101201 or 17011102204 be used as direct replacements for the TE Connectivity 5188731-1?
A: HARTING parts are mechanically compatible with identical position count (110), pitch (2.00mm), row configuration (5), and mounting type (through hole). However, the HARTING parts are rated for 1.0A current versus the TE Connectivity specification of 1.5A. Selection depends on application current requirements. Both HARTING parts are active products with current compliance certifications.
Q: What is the difference between the Amphenol ICC (FCI) 110-position and 154-position configurations?
A: The 110-position parts (HM2P07PA5110AALF, HM2P07PD5110N9LF, HM2P07PD51M0N9LF, HM2P07PDE120N9LF, HM2P07PDG3W0N9L1LF) maintain the same 5-row configuration as the TE Connectivity 5188731-1. The 154-position parts (HM2P07PA5111AALF, HM2P07PD5111N9LF) feature a 5+2 row configuration with 44 additional ground positions integrated into the connector. The 154-position variants are suitable for applications requiring dedicated grounding planes.
Q: Are all substitute parts RoHS compliant?
A: All active substitute parts listed are RoHS compliant. The TE Connectivity 5188731-1 is RoHS Compliant. HARTING parts 17011101201 and 17011102204 are ROHS3 Compliant. All Amphenol ICC (FCI) Millipacs® parts are RoHS Compliant. The HM2H07P115LF shroud is RoHS Compliant but is an obsolete product.
Q: What is the voltage rating difference between the TE Connectivity part and Amphenol ICC (FCI) substitutes?
A: The TE Connectivity 5188731-1 is rated for 500Vrms. All active Amphenol ICC (FCI) Millipacs® substitute parts are rated for 750Vrms, providing higher voltage capability in the same form factor. HARTING parts do not specify voltage ratings in the provided data.
Q: Can the HM2H07P115LF shroud be used with the TE Connectivity 5188731-1?
A: The HM2H07P115LF is a shroud component designed for 110-position hard metric connectors and is compatible with the TE Connectivity 5188731-1 mechanically. However, this part is obsolete and not recommended for new designs. The shroud is a complementary accessory for connector protection and alignment, not a substitute for the header connector itself.
Q: What packaging options are available for substitute parts?
A: The TE Connectivity 5188731-1 is supplied in tube packaging. HARTING parts 17011101201 and 17011102204 are supplied in tube packaging. Amphenol ICC (FCI) Millipacs® parts are supplied in tray packaging. The HM2H07P115LF shroud packaging is not specified. Packaging differences do not affect electrical or mechanical compatibility.
Q: Are all substitute parts currently in production?
A: All substitute parts except HM2H07P115LF are active products in current production. The HM2H07P115LF is listed as obsolete and should not be selected for new designs. All active substitute parts have confirmed inventory availability.
