Key Parameters

Substitute Part Grouping Explanation

The 74981-302LF qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution criteria are determined by the following parameters, all of which match between the main part and substitute:

• Connector type and style (Receptacle, Female Sockets, High Speed)
• Position count and pitch (108 positions, 0.079" / 2.00mm)
• Physical configuration (8 rows, board edge mounting, right angle, through hole)
• Termination method (Press-Fit)
• Contact layout (96 Signal, 12 Ground)
• Current and temperature ratings (1A, -55°C ~ 105°C)
• Contact finish specification (Gold or Gold, GXT™)
• Flammability rating (UL94 V-0)
• Series designation (Metral® 1000)

Parameter Comparison

Engineering Selection Recommendations

The 74981-302LF is the direct equivalent for the obsolete 74981-302. Selection of the substitute part is based on the following factors:

Product Status: The 74981-302 is classified as obsolete, while the 74981-302LF maintains active product status. This distinction makes the 74981-302LF the appropriate choice for new designs and ongoing system support where component availability is required.

Electrical and Mechanical Compatibility: All critical electrical parameters, mechanical dimensions, and contact specifications are identical between the two parts. The connector maintains the same 108-position configuration, 0.079" pitch, press-fit termination, and contact layout.

Compliance and Certifications: Both parts share identical compliance profiles, including UL94 V-0 flammability rating, MSL 1 moisture sensitivity level, and RoHS non-compliant status. ECCN and HTSUS classifications are identical.

Packaging Consideration: The 74981-302LF is supplied in tube packaging, which may differ from the original part's packaging specification. Verify packaging requirements for your procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 74981-302LF directly replace the 74981-302 in existing designs?

A: Yes. The 74981-302LF is electrically and mechanically identical to the 74981-302. All contact specifications, pitch, position count, mounting configuration, and termination method are equivalent. The substitute part is suitable for direct replacement in board-level applications.

Q: What is the primary reason for substitution?

A: The 74981-302 is obsolete. The 74981-302LF is the active equivalent from the same manufacturer and series, ensuring continued component availability for production and field support.

Q: Are there any differences in contact finish or plating?

A: No. Both parts specify gold or gold GXT™ contact finish with identical thickness of 31.5µin (0.80µm). Contact performance and durability characteristics are equivalent.

Q: Does the packaging difference affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. The 74981-302LF is supplied in tube packaging. Verify that your assembly and procurement processes accommodate this packaging format.

Q: Are compliance certifications identical?

A: Yes. Both parts carry identical UL94 V-0 flammability rating, MSL 1 moisture sensitivity level, and RoHS non-compliant status. ECCN and HTSUS classifications are the same.

Q: What is the current rating for this connector?

A: Both the 74981-302 and 74981-302LF are rated for 1A per contact. Operating temperature range is -55°C to 105°C.

Q: Are there any lead-free variants available?

A: The provided data indicates both parts are RoHS non-compliant. No lead-free variants are listed in the substitute information.
