Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PIS-0390 are determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency Range: 860MHz ~ 930MHz
• Center Frequency: 895MHz
• Antenna Type: Whip, Straight
• Gain: 5.8dBi
• Termination: N Type Male
• Mounting Type: Bracket Mount
• Power - Max: 20 W
• RF Family/Standard: General ISM
• Frequency Group: UHF (300MHz ~ 1GHz)
• Applications: LoRa
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variations:

• Product Status (Active or Obsolete)
• Height (Max): Variations permitted within mechanical envelope constraints
• Manufacturer designation (Pi Supply variants)
• Packaging configuration
• Compliance certifications (RoHS status)

The substitute parts identified maintain electrical performance equivalence through identical RF specifications while accommodating mechanical and compliance variations appropriate for direct component substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: NBR-0042

The NBR-0042 is the preferred substitute for PIS-0390 applications. This part maintains complete electrical equivalence across all RF parameters while offering Active product status, ensuring ongoing manufacturer support and supply availability. The NBR-0042 carries RoHS3 compliance certification, meeting current environmental and regulatory requirements. The reduced physical height (19.685" versus 31.496") accommodates space-constrained installations while preserving antenna performance characteristics.

Secondary Recommendations: PIS-0386, PIS-0387, PIS-0391, PIS-0392, PIS-0394

These parts provide parametric equivalence to PIS-0390 with identical electrical specifications and mechanical mounting compatibility. All secondary options maintain the full 31.496" height dimension. Selection among these alternatives depends on connector type requirements and mechanical integration constraints. All secondary options carry Obsolete status; selection should prioritize inventory availability and project timeline requirements.

Compliance Consideration

NBR-0042 is the only substitute carrying explicit RoHS3 compliance documentation. Applications subject to RoHS regulatory requirements should prioritize NBR-0042 selection.

Frequently Asked Questions (FAQ)

Q: Can PIS-0390 be directly replaced with NBR-0042?

A: Yes. NBR-0042 provides complete electrical equivalence across frequency range, gain, termination type, and power rating. The reduced physical height (500mm versus 800mm) requires mechanical integration verification but does not affect RF performance parameters.

Q: What is the primary difference between PIS-0390 and the secondary substitute options?

A: All substitute parts maintain identical RF specifications (860MHz ~ 930MHz frequency range, 5.8dBi gain, N Type Male termination, 20W power rating). Secondary options differ in product status (all Obsolete) and inventory availability. NBR-0042 is the only Active status part with RoHS3 compliance.

Q: Are there connector type variations among the substitute parts?

A: All listed substitutes maintain N Type Male termination, consistent with PIS-0390. Connector compatibility is preserved across the entire substitute family.

Q: Does antenna height affect RF performance?

A: Height variation between PIS-0390 (800mm) and NBR-0042 (500mm) does not alter the specified electrical parameters (frequency range, gain, power rating). Mechanical mounting envelope and physical installation space represent the primary considerations for height selection.

Q: Which substitute part should be selected for new designs?

A: NBR-0042 is specified for new designs. Active product status ensures manufacturer support, supply continuity, and RoHS3 compliance certification. Secondary options are appropriate only for legacy system maintenance where inventory availability and cost considerations override compliance requirements.

Q: Are all substitute parts suitable for LoRa applications?

A: Yes. All substitute parts carry LoRa application designation and maintain the General ISM RF family standard required for LoRa network infrastructure.
