Key Parameters

Substitute Part Grouping Explanation

The 88951-101LF qualifies as a direct substitute based on the following critical parameters that define functional and mechanical compatibility:

• Connector Position Count: Both parts feature 24 positions
• Pitch Configuration: Identical 0.079" (2.00mm) pitch
• Row Configuration: Both configured as 4-row headers
• Connector Type: Both are header connectors with male pins
• Mounting Method: Both use through-hole PCB mounting
• Termination Type: Both use solder termination
• Contact Material & Finish: Both feature gold-plated contacts at 30.0µin (0.76µm) thickness
• Current Rating: Both rated for 1A
• Operating Temperature: Both operate across -55°C ~ 125°C
• Flammability Rating: Both meet UL94 V-0 standard
• Base Product Number: Both share the 88951 base designation

The primary distinction is product status: 88951-101 is obsolete while 88951-101LF is active, with improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 88951-101LF is the appropriate selection for new designs and component replenishment due to the following factors:

Product Status: The 88951-101 is classified as obsolete, indicating discontinued manufacturing and limited future availability. The 88951-101LF maintains active product status with ongoing manufacturing support.

Regulatory Compliance: The 88951-101LF achieves RoHS compliance, meeting current environmental and hazardous substance restrictions. The original 88951-101 does not meet RoHS requirements. For applications subject to RoHS directives or customer specifications requiring RoHS compliance, the 88951-101LF is mandatory.

REACH Compliance: The 88951-101LF is REACH-affected, indicating full compliance with chemical substance registration requirements. This status is preferable for applications in regulated markets.

Functional Equivalence: All electrical and mechanical parameters remain identical between the two parts, ensuring direct PCB-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can 88951-101LF be used as a direct replacement for 88951-101 on existing PCBs?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), position count (24), row configuration (4), mounting type (through-hole), and termination method (solder). No PCB layout modifications are required.

Q: What is the significance of the "LF" designation in 88951-101LF?

A: The "LF" suffix indicates lead-free construction and RoHS compliance. This designation reflects the part's adherence to current environmental regulations and hazardous substance restrictions.

Q: Are there packaging differences between 88951-101 and 88951-101LF?

A: The 88951-101LF is supplied in tube packaging. The original 88951-101 packaging specification is not provided in the technical data. Verify packaging requirements for your procurement and assembly processes.

Q: Why is 88951-101 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 88951-101LF represents the active equivalent that supersedes the original part, ensuring continued availability and regulatory compliance.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts maintain 1A current rating, -55°C ~ 125°C operating temperature range, UL94 V-0 flammability rating, and identical contact finish specifications (gold, 30.0µin thickness).

Q: Which part should be specified for new designs?

A: Specify 88951-101LF for all new designs. This part is active, RoHS compliant, and functionally equivalent to the obsolete 88951-101.
