Key Parameters

Substitute Part Grouping Explanation

Substitution for the 89891-308 is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle, bottom or top entry configuration
• Contact arrangement: 16 positions in 2-row configuration
• Pitch specification: 0.100" (2.54mm) mating pitch with 0.100" row spacing
• Mounting method: Through-hole solder termination
• Contact system: Female socket with gold mating finish and tin post finish
• Insulation properties: Thermoplastic, glass-filled material with UL94 V-0 rating
• Series compatibility: Dubox™ series

The substitute part 89891-308LF maintains identical electrical and mechanical specifications while differing in product status and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 89891-308LF serves as the direct functional equivalent to the obsolete 89891-308. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and footprint compatibility in board-to-board applications.

The primary distinction between these parts is regulatory and availability status. The 89891-308LF is currently in active production with RoHS compliance certification, whereas the 89891-308 is obsolete and RoHS non-compliant. For new designs or system refreshes, the 89891-308LF is the appropriate selection. For legacy system maintenance where the original 89891-308 specification must be retained, the 89891-308LF provides equivalent performance with improved regulatory alignment.

Packaging differs between the two parts: the 89891-308 is supplied in bulk format, while the 89891-308LF is packaged in tubes. This distinction affects procurement and handling procedures but does not impact functional performance.

Frequently Asked Questions (FAQ)

Q: Are the 89891-308 and 89891-308LF mechanically interchangeable?

A: Yes. Both parts are identical in connector type, position count, pitch spacing, mounting method, and contact configuration. They share the same footprint and are directly interchangeable in board-to-board applications.

Q: What is the significance of the "LF" suffix in the 89891-308LF part number?

A: The "LF" designation indicates lead-free compliance, reflecting the part's RoHS compliance status. The 89891-308LF meets RoHS requirements, whereas the original 89891-308 does not.

Q: Can the 89891-308 be used in new designs?

A: The 89891-308 is obsolete and RoHS non-compliant. For new designs, the 89891-308LF is the appropriate selection. Existing designs using the 89891-308 may continue operation, but procurement of new stock should transition to the 89891-308LF.

Q: Does packaging format affect connector performance?

A: No. The difference between bulk and tube packaging is a logistics and handling consideration only. Connector electrical and mechanical performance is identical regardless of packaging format.

Q: Are there any electrical parameter differences between these parts?

A: No. Both parts maintain identical contact finish specifications (gold mating, tin post), insulation material properties, and flammability ratings. Electrical performance is equivalent.

Q: What applications are these connectors suitable for?

A: Both the 89891-308 and 89891-308LF are specified for automotive, general purpose, industrial, and telecommunications applications.
