Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76745-110-72 is determined by the following critical parameters:

• Number of Positions and Pitch: Substitute parts must maintain 72 positions at 0.100" (2.54mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Row Configuration: The 2-row arrangement with 0.100" (2.54mm) row spacing is a fundamental geometric requirement.
• Mounting and Termination: Through-hole mounting with solder termination must be preserved.
• Contact Finish Specifications: Gold plating at 30.0µin (0.76µm) thickness on mating posts ensures signal integrity and corrosion resistance.
• Physical Dimensions: Stack height, overall pin length, and tail length must remain within the specified tolerances for PCB assembly compatibility.

Based on these parameters, the following parts are identified as direct substitutes:

76745-110-72LF — Direct equivalent with identical electrical and mechanical specifications. Active product status with RoHS compliance.

87606-325LF — Cross-manufacturer alternative with different connector type (receptacle vs. header) and position count (50 vs. 72). This part does not meet substitution criteria due to fundamental incompatibility in position count and connector configuration.

Parameter Comparison

Engineering Selection Recommendations

76745-110-72LF is the primary substitute for the obsolete 76745-110-72. Both parts share identical electrical and mechanical specifications, including position count, pitch, row configuration, contact finish, and physical dimensions. The key distinction is product status: 76745-110-72LF is active and carries RoHS compliance certification, making it suitable for new designs and production environments with regulatory requirements. The transition from REACH Unaffected to REACH Affected status reflects current compliance frameworks.

87606-325LF is not a suitable substitute. Although it shares the same pitch and row spacing, it is a receptacle connector with only 50 positions, fundamentally incompatible with applications designed for the 72-position header configuration. Position count mismatch prevents direct substitution regardless of other parameter alignment.

For applications currently using the obsolete 76745-110-72, migration to 76745-110-72LF is the appropriate path forward, provided that RoHS compliance and REACH status changes are acceptable within the application's regulatory framework.

Frequently Asked Questions (FAQ)

Q: Can 87606-325LF replace 76745-110-72?

A: No. The 87606-325LF is a 50-position receptacle connector, while the 76745-110-72 is a 72-position header. The position count difference makes these parts incompatible. Mating connectors and PCB layouts designed for 72 positions cannot accommodate a 50-position connector.

Q: What is the difference between 76745-110-72 and 76745-110-72LF?

A: Both parts are electrically and mechanically identical with 72 positions, 0.100" pitch, and gold-plated contacts. The primary differences are product status (obsolete vs. active) and compliance certifications. The 76745-110-72LF is RoHS compliant and REACH affected, while the original part is non-compliant and REACH unaffected.

Q: Are there packaging differences between the main part and substitute?

A: Yes. The 76745-110-72 is supplied in unspecified packaging, while the 76745-110-72LF is supplied in bulk packaging. This distinction affects inventory management and handling procedures but does not impact electrical or mechanical performance.

Q: Does the GXT™ contact finish on 76745-110-72LF match the original part?

A: Yes. Both parts feature gold GXT™ plating at 30.0µin (0.76µm) thickness on mating posts, ensuring equivalent signal integrity and corrosion resistance.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both the main part and substitute carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
