RF Power Divider 40170 Equivalent & Substitute Parts

Part Overview

The TTM Technologies 40170 is an RF power divider module designed for operation in the 700 MHz to 1.4 GHz frequency band with a minimum isolation of 18 dB and insertion loss of 0.6 dB. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. The module format and electrical specifications define the scope for substitute part evaluation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for RF power dividers are evaluated based on frequency coverage, isolation performance, insertion loss characteristics, and physical package compatibility. The PWD-5520-T2-NNN-79 from Cinch Connectivity Solutions Midwest Microwave qualifies as a substitute because:

• Frequency range (500 MHz ~ 2 GHz) encompasses the original 700 MHz ~ 1.4 GHz band
• Isolation specification (20 dB minimum) meets or exceeds the 18 dB requirement
• Insertion loss (0.5 dB) is equal to or better than the original 0.6 dB specification
• Module package format maintains form factor compatibility
• Moisture sensitivity level (1, Unlimited) matches the original component

Parameter Comparison

Engineering Selection Recommendations

The PWD-5520-T2-NNN-79 is suitable for applications currently using the 40170. The substitute part offers improved electrical performance with lower insertion loss and higher isolation within an expanded frequency range that fully covers the original operating band. The active product status of the PWD-5520-T2-NNN-79 ensures ongoing availability and manufacturer support, addressing the obsolescence of the original component.

Physical dimensions differ between the two modules (40170: 3.000" L × 0.900" W × 0.110" H; PWD-5520-T2-NNN-79: 2.000" L × 1.000" W), requiring mechanical integration verification in space-constrained applications.

The RoHS non-compliance status of the PWD-5520-T2-NNN-79 should be evaluated against system-level compliance requirements. Both components share identical ECCN classification (EAR99) for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can the PWD-5520-T2-NNN-79 directly replace the 40170 in existing designs?

A: Electrical substitution is valid based on frequency coverage, isolation, and insertion loss specifications. Mechanical integration requires verification due to dimensional differences. The substitute module is smaller in length and width but maintains the same height profile.

Q: What is the frequency overlap between these components?

A: The 40170 operates from 700 MHz to 1.4 GHz. The PWD-5520-T2-NNN-79 operates from 500 MHz to 2 GHz, providing complete coverage of the original frequency band with extended range capability.

Q: Are there compliance differences between the two parts?

A: Both components share EAR99 export classification. The PWD-5520-T2-NNN-79 is RoHS non-compliant, whereas RoHS status is not specified for the 40170. System-level compliance requirements must be evaluated independently.

Q: What is the isolation performance difference?

A: The PWD-5520-T2-NNN-79 provides 20 dB minimum isolation compared to the 40170's 18 dB minimum, representing a 2 dB improvement in channel separation.

Q: How do insertion loss values compare?

A: The PWD-5520-T2-NNN-79 exhibits 0.5 dB insertion loss versus the 40170's 0.6 dB, providing 0.1 dB lower loss in signal transmission.
