Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Rosenberger 02K246-40ML5 is determined by strict equivalence across the following parameters:

• Connector style and type (2.92mm jack, female socket)
• Electrical specifications (50-ohm impedance, 40 GHz maximum frequency)
• Mechanical configuration (board edge, cutout mounting; surface mount solder termination)
• Environmental ratings (operating temperature -40°C to 85°C; 250 V voltage rating)
• Reliability specifications (500 mating cycles minimum)

Parts meeting all these criteria are classified as parametric equivalents and may be used interchangeably in applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core parametric requirements for direct substitution. Selection should be based on the following factors:

Rosenberger 02K246-40ML5: Primary choice with RoHS compliance certification and active production status. Suitable for applications requiring standard RoHS compliance.

Rosenberger 02K249-40ML5: Parametric equivalent from the same manufacturer. Provides continuity within the Rosenberger RPC series. Recommended when supply of the primary part is constrained.

Cinch Connectivity Solutions 145-0701-811: Parametric equivalent from alternative manufacturer. Offers ROHS3 compliance and REACH compliance documentation. Inventory availability is higher (3239 units). Suitable for applications requiring enhanced environmental compliance certifications or when Rosenberger parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can 02K249-40ML5 be used as a direct replacement for 02K246-40ML5?

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters including connector style, impedance, frequency rating, mounting configuration, and environmental ratings.

Q: What is the difference between the Rosenberger and Cinch parts?

A: The Cinch 145-0701-811 is a parametric equivalent with identical functional specifications. Differences exist only in manufacturer identity, RoHS certification level (ROHS3 vs. RoHS), REACH compliance status, and packaging format (Bulk vs. standard).

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist when substituting between these three parts. All meet identical specifications for connector style, impedance, frequency range, mounting type, and termination method.

Q: Which part should be selected for new designs?

A: Selection should prioritize based on supply availability, required compliance certifications, and manufacturer preference. All three parts are functionally equivalent for 2.92mm 50-ohm RF applications up to 40 GHz.

Q: What does "parametric equivalent" mean in this context?

A: A parametric equivalent part meets all specified electrical and mechanical parameters required for the application. The parts are interchangeable from a functional standpoint within the defined operating conditions.
