Substitute Part Grouping Explanation

Substitution eligibility for the 76345-804-72LF is determined by strict alignment with the following core parameters:

• Connector type: Header
• Contact type: Male pin
• Pitch - mating: 0.100" (2.54mm)
• Number of positions: 72
• Number of rows: 2
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole, right angle
• Style: Board to board
• Termination: Solder
• Contact shape: Square
• Contact material: Phosphor bronze or copper alloy
• Insulation material: Thermoplastic or thermoplastic glass-filled
• Material flammability rating: UL94 V-0
• Insulation color: Black
• Moisture sensitivity level: 1 (Unlimited)

The substitute parts identified below meet these core electrical and mechanical requirements and are therefore functionally equivalent for applications requiring the 76345-804-72LF.

Parameter Comparison

Engineering Selection Recommendations

The 68697-272HLF from Amphenol ICC (FCI) is the primary substitute for the obsolete 76345-804-72LF. Both connectors are from the same manufacturer and share identical core electrical and mechanical specifications. The 68697-272HLF is an active product with RoHS compliance status, making it suitable for new designs and ongoing production support. Minor dimensional variations in contact length and insulation height are within acceptable tolerances for board-to-board applications.

The 2372-5121-TG from 3M is a secondary substitute option. This connector meets all core substitution criteria and is an active product. However, it is RoHS non-compliant and subject to REACH regulations. The 2372-5121-TG features a glass-filled thermoplastic insulation material and specifies an operating temperature range of -55°C to 105°C, providing additional thermal performance data. The lower contact post length (0.110" versus 0.126") and reduced current rating (3A versus 5A) should be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 68697-272HLF directly replace the 76345-804-72LF in existing assemblies?

A: Yes. Both connectors share identical pitch (0.100"), position count (72), row configuration (2 rows), mounting type (through-hole right angle), and core electrical specifications. The 68697-272HLF is the manufacturer-recommended substitute and maintains functional compatibility.

Q: What are the key differences between the 76345-804-72LF and 68697-272HLF?

A: The primary differences are product status (obsolete versus active) and compliance certifications. The 68697-272HLF is RoHS compliant. Minor dimensional variations exist in contact length and insulation height, but these do not affect electrical or mechanical compatibility for standard board-to-board applications.

Q: Is the 2372-5121-TG suitable for applications requiring RoHS compliance?

A: No. The 2372-5121-TG is RoHS non-compliant and subject to REACH regulations. For applications requiring RoHS compliance, the 68697-272HLF is the appropriate choice.

Q: What is the significance of the contact length differences between these connectors?

A: Contact length variations (0.240" for 76345-804-72LF, 0.230" for 68697-272HLF, and 0.230" for 2372-5121-TG) reflect design differences between connector series. These variations are within acceptable tolerances for standard board-to-board mating and do not affect electrical performance or mechanical engagement.

Q: Are there packaging differences between the substitute parts?

A: The 68697-272HLF is supplied in bag packaging. The 76345-804-72LF and 2372-5121-TG do not specify packaging format in the provided data. Packaging differences do not affect connector functionality and are primarily relevant for inventory and handling procedures.

Q: What current and voltage ratings should be used for design calculations?

A: The 68697-272HLF specifies 5A at 110V. The 2372-5121-TG specifies 3A with no voltage rating provided. The original 76345-804-72LF does not specify current or voltage ratings. For applications requiring specific electrical performance, the 68697-272HLF provides the most complete electrical specifications.
