Key Parameters

Substitute Part Grouping Explanation

Substitution for the TBCF81 is determined by the following critical parameters:

• Connector Type & Series: F81 connector specification
• Manufacturer: Belden Inc. (same manufacturer ensures design consistency)
• Category: Coaxial Connectors (RF)
• Compliance & Certifications: REACH Status and ECCN classification

• HTSUS Classification: 8536.69.4010

The substitute part CF81GHZM maintains all these parameters while offering active product status and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The CF81GHZM serves as the direct substitute for the obsolete TBCF81. Both components share identical compliance classifications (REACH Unaffected, ECCN EAR99) and moisture sensitivity ratings (MSL 1). The CF81GHZM is manufactured by the same supplier (Belden Inc.) and maintains the same HTSUS classification, ensuring regulatory and procurement consistency.

The primary distinction is product status: CF81GHZM holds active status with confirmed inventory availability (1150 pcs), whereas TBCF81 is obsolete. For new designs or component replenishment, CF81GHZM is the appropriate selection. Both parts are classified as F81 connectors within the coaxial RF connector category, confirming functional equivalence for applications requiring this connector type.

Frequently Asked Questions (FAQ)

Q: Can CF81GHZM directly replace TBCF81 in existing applications? A: Yes. Both parts are F81 connectors manufactured by Belden Inc. with identical MSL ratings, REACH status, and ECCN classifications. The CF81GHZM is the active equivalent of the obsolete TBCF81.

Q: What is the difference between TBCF81 and CF81GHZM? A: The primary difference is product status. TBCF81 is obsolete, while CF81GHZM is active. CF81GHZM is supplied in bulk packaging. Both maintain identical electrical and compliance specifications.
