53AS102-K10N3 Equivalent & Substitute Parts

Part Overview

The 53AS102-K10N3 is an N-Type RF attenuator manufactured by Rosenberger, designed for RF signal attenuation applications across a broad frequency spectrum. This active product provides 10dB attenuation with 2W power handling capability and 50-ohm impedance matching. The part is available in N-Type in-line module packaging, suitable for direct integration into RF transmission systems. Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across the critical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 53AS102-K10N3 is determined by matching the following critical parameters:

• Attenuation Value: 10dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Package Type: N-Type In-Line Module (exact match required)
• Power Rating: 2W (minimum requirement)
• Frequency Range: Must encompass or exceed 0 Hz ~ 12.4 GHz
• Product Status: Active (current production)
• Environmental Compliance: RoHS Compliant or equivalent

The substitute part ATT-0219-10-NNN-02 meets all substitution criteria with extended frequency coverage to 18 GHz, maintaining identical attenuation, impedance, power handling, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

The ATT-0219-10-NNN-02 is a qualified substitute for the 53AS102-K10N3 based on matching electrical specifications and package configuration. Both parts maintain active product status and meet RoHS environmental compliance requirements. The substitute part provides extended frequency coverage to 18 GHz, which encompasses the original part's 12.4 GHz upper limit. Selection between these parts may be determined by supply chain availability, lead time requirements, or specific application frequency constraints within the 0 Hz to 12.4 GHz operating window.

Frequently Asked Questions (FAQ)

Q: Can ATT-0219-10-NNN-02 be used as a direct replacement for 53AS102-K10N3?

A: Yes. Both parts share identical attenuation (10dB), impedance (50 Ohms), power rating (2W), and N-Type in-line module packaging. The substitute part's extended frequency range to 18 GHz is compatible with applications requiring operation up to 12.4 GHz.

Q: What are the critical parameters for substitution?

A: Attenuation value, impedance, power rating, package type, and frequency range coverage. All must match or exceed the original specification. Both parts meet these requirements.

Q: Are there packaging differences between these parts?

A: Both parts use N-Type in-line module packaging. The primary difference is packaging format: 53AS102-K10N3 is specified with standard packaging, while ATT-0219-10-NNN-02 is supplied in bulk packaging. This does not affect electrical or mechanical compatibility.

Q: Do both parts meet environmental compliance standards?

A: Yes. The 53AS102-K10N3 is RoHS Compliant, and the ATT-0219-10-NNN-02 is ROHS3 Compliant. Both meet current environmental regulations for electronic components.

Q: What is the frequency range difference, and does it matter?

A: The original part operates to 12.4 GHz, while the substitute operates to 18 GHz. For applications within the 12.4 GHz limit, both parts perform identically. The extended range of the substitute provides additional operational margin without performance degradation in the original frequency band.
