PIS-0384 LoRa Antenna Equivalent & Substitute Parts

Part Overview

The PIS-0384 is a multi-band LoRa whip antenna manufactured by Pi Supply, designed for ISM band applications across 433MHz, 470MHz, 868MHz, 915MHz, and 923MHz frequency bands. The antenna features a 3dBi gain rating with N Type connector termination and connector mount configuration. This part is currently listed as obsolete, making identification of functionally equivalent substitute components essential for ongoing system design and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIS-0384 is determined by the following critical parameters:

Primary Substitution Criteria:

• Antenna type classification (Whip, Straight configuration)
• Termination connector type (N Type)
• Gain specification (3dBi)
• RF family standard (General ISM)
• Frequency band coverage compatibility with 915MHz and 868MHz primary operating bands
• Moisture sensitivity level (MSL 1 or equivalent)

Secondary Compatibility Factors:

• Mounting interface compatibility (connector or bracket mount acceptable for system-level integration)
• Product status (active status preferred for long-term availability)
• Regulatory compliance (ECCN and RoHS certifications)

The NBR-0040 qualifies as a direct substitute based on matching antenna type, N Type termination, 3dBi gain specification, and frequency range coverage that encompasses the critical 915MHz and 868MHz bands within its 860MHz to 930MHz operating range.

Engineering Selection Recommendations

Primary Substitute: NBR-0040

The NBR-0040 serves as the direct functional equivalent for PIS-0384 applications. Selection rationale is based on the following engineering factors:

Electrical Compatibility: The NBR-0040 maintains identical electrical specifications across all critical parameters: 3dBi gain, N Type termination, and ISM band operation. The frequency range of 860MHz to 930MHz encompasses both the 915MHz and 868MHz bands that represent the primary LoRa operating frequencies in most global deployments.

Product Lifecycle Status: The NBR-0040 holds active product status with current manufacturing availability (1037 units in stock), providing supply chain continuity for the obsolete PIS-0384. This status ensures long-term component availability and technical support.

Regulatory and Compliance Alignment: The NBR-0040 carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both parts share identical EAR99 export classification and MSL 1 moisture sensitivity ratings.

Mechanical Integration Consideration: The primary difference between parts is the mounting interface: PIS-0384 uses connector mount while NBR-0040 uses bracket mount. System designers must evaluate mechanical mounting compatibility within their specific application enclosure or antenna mounting structure. The N Type connector termination remains identical, requiring only mechanical bracket adaptation at the system level.

Frequently Asked Questions (FAQ)

Q: Can NBR-0040 directly replace PIS-0384 in existing designs?

A: Electrical substitution is direct and complete. The N Type connector termination is identical, and all RF specifications match. Mechanical mounting requires assessment: if the original design uses connector mount, the bracket mount configuration of NBR-0040 requires mechanical adapter or mounting structure modification.

Q: Are the frequency bands fully compatible?

A: Yes. The NBR-0040 frequency range of 860MHz to 930MHz fully covers the 915MHz and 868MHz bands used in standard LoRa applications. The PIS-0384 also supports 433MHz, 470MHz, and 923MHz; however, the NBR-0040 does not cover these extended bands. Verify that your application operates exclusively within the 860MHz to 930MHz range before substitution.

Q: What is the impact of the different mounting types?

A: PIS-0384 uses connector mount (antenna connects directly via N Type connector), while NBR-0040 uses bracket mount (antenna mounts to a bracket structure). This is a mechanical interface difference only. The RF connector type remains N Type in both cases. System integration requires mechanical bracket compatibility assessment.

Q: Is the gain specification identical?

A: Yes. Both PIS-0384 and NBR-0040 specify 3dBi gain, ensuring equivalent RF performance in LoRa system designs.

Q: What is the availability status of each part?

A: PIS-0384 is obsolete with 1090 units remaining in stock. NBR-0040 is active production with 1037 units in stock. For new designs or long-term production, NBR-0040 is the recommended selection due to active manufacturer support.

Q: Are there any compliance differences?

A: NBR-0040 carries explicit ROHS3 compliance certification. Both parts share EAR99 export classification and MSL 1 moisture sensitivity ratings. For applications requiring current environmental compliance documentation, NBR-0040 provides certified compliance status.

Q: Can I use NBR-0040 if my system requires 433MHz or 470MHz operation?

A: No. The NBR-0040 frequency range is 860MHz to 930MHz and does not support 433MHz or 470MHz bands. If your application requires these lower frequency bands, NBR-0040 is not suitable. Consult alternative LoRa antenna options that support the full frequency range.
