Key Parameters

Substitute Part Grouping Explanation

The 88949-102LF qualifies as a direct substitute for the 88949-202LF based on the following critical parameters that determine functional compatibility:

• Connector Type & Style: Both are receptacle connectors with female blade sockets in blade power configuration
• Position Count & Layout: Both feature 8 positions with 4 rows in 8 power contact layout
• Mounting Configuration: Both use board edge, through hole, right angle mounting with press-fit termination
• Mechanical Features: Both include board guide and spacer features
• Electrical Ratings: Both are rated for 3A current, 1000V voltage, and -55°C to 105°C operating temperature
• Material Compliance: Both meet UL94 V-0 flammability rating
• Moisture Sensitivity: Both have MSL 1 (Unlimited)

The primary distinction is product status: the 88949-202LF is obsolete while the 88949-102LF is active, with enhanced contact finish specifications (gold plating at 30.0µin/0.76µm) and full RoHS and REACH compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The 88949-102LF is the appropriate selection for applications currently using or specifying the 88949-202LF. The substitute part maintains identical electrical and mechanical specifications across all critical parameters: 8-position blade power receptacle configuration, 3A/1000V ratings, press-fit termination, and -55°C to 105°C operating range.

The 88949-102LF offers additional advantages through active product status, documented RoHS compliance, REACH compliance status, and specified gold contact finish (30.0µin/0.76µm thickness). These enhancements provide improved long-term supply chain availability and regulatory documentation for modern manufacturing environments.

Both parts share the same base product number (88949), series designation (Metral®), and core mechanical interface, ensuring direct compatibility in existing designs without modification to PCB layouts or mating connectors.

Frequently Asked Questions (FAQ)

Q: Can the 88949-102LF be used as a direct replacement for the 88949-202LF in existing designs?

A: Yes. Both connectors share identical specifications for connector type, position count, mounting configuration, electrical ratings, and operating temperature range. No design modifications are required.

Q: What is the significance of the contact finish difference?

A: The 88949-102LF specifies gold plating at 30.0µin (0.76µm) thickness, while the 88949-202LF does not specify contact finish. Gold plating provides enhanced corrosion resistance and contact reliability. This represents an improvement in the substitute part.

Q: Are there compliance or regulatory differences between these parts?

A: The 88949-102LF includes documented RoHS Compliance and REACH Affected status. The 88949-202LF does not specify these compliance statuses. For applications requiring regulatory documentation, the 88949-102LF provides explicit compliance certification.

Q: What packaging is available for the 88949-102LF?

A: The 88949-102LF is supplied in Tube packaging. Confirm packaging requirements for your procurement process.

Q: Why is the 88949-202LF listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation. The 88949-102LF represents the active equivalent within the Metral® series, ensuring continued availability and support.

Q: Are the electrical and thermal specifications identical?

A: Yes. Both parts are rated for 3A current, 1000V voltage, UL94 V-0 flammability, and -55°C to 105°C operating temperature. Thermal and electrical performance are equivalent.
