Key Parameters

Substitute Part Grouping Explanation

The 91618-312LF serves as a direct functional equivalent to the 91618-312. Substitution eligibility is determined by strict alignment of the following critical parameters:

• Connector type and style (Receptacle, Bottom or Top Entry, Board to Board)
• Contact configuration (24 positions, 2 rows, 0.100" pitch spacing)
• Mounting technology (Surface Mount with solder termination)
• Contact material and finish specifications (Gold mating surface, Phosphor Bronze base, Tin post finish)
• Mechanical features (Push-Pull fastening, Board Lock, 10.81mm mated stacking height)
• Environmental and material certifications (UL94 V-0 flammability rating, Thermoplastic Glass Filled insulation)

The primary distinction between these parts is product status and regulatory compliance, not electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The 91618-312LF is the direct active equivalent for the obsolete 91618-312. All electrical and mechanical parameters are identical, ensuring functional interchangeability in board-to-board connector applications.

The 91618-312LF carries RoHS Compliant status and REACH Affected designation, whereas the 91618-312 is RoHS non-compliant and REACH Unaffected. For new designs or applications subject to RoHS or REACH regulatory requirements, the 91618-312LF is the appropriate selection. For legacy systems or applications without regulatory constraints, either part meets the identical functional specification.

The 91618-312LF is supplied in Tube packaging, while packaging information for the 91618-312 is not specified in the available data.

Frequently Asked Questions (FAQ)

Q: Can the 91618-312LF directly replace the 91618-312 in existing designs?

A: Yes. The 91618-312LF is functionally identical to the 91618-312 across all electrical and mechanical parameters, including connector type, position count, pitch spacing, contact materials, finishes, and mechanical features. Direct substitution is supported without design modification.

Q: What is the primary difference between these two parts?

A: The primary differences are product status and regulatory compliance. The 91618-312 is obsolete and RoHS non-compliant, while the 91618-312LF is active and RoHS Compliant. All functional specifications are identical.

Q: Are there any compatibility concerns with packaging differences?

A: The 91618-312LF is supplied in Tube packaging. Packaging format does not affect connector functionality or interchangeability. Verify that your assembly process accommodates the specified packaging format.

Q: Which part should be selected for new designs?

A: The 91618-312LF should be selected for new designs. It is the active product with current regulatory compliance status (RoHS Compliant, REACH Affected).

Q: Are the contact finishes and thicknesses identical?

A: Yes. Both parts feature identical gold mating contact finish at 30.0µin (0.76µm) thickness and tin post finish at 78.7µin (2.00µm) thickness. Contact material (Phosphor Bronze) and all other contact specifications are identical.

Q: Do both parts meet the same flammability and environmental standards?

A: Yes. Both parts carry UL94 V-0 material flammability rating and identical Moisture Sensitivity Level (MSL 1 - Unlimited). Environmental and material certifications are equivalent.
