Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIS-0382 is determined by the following critical parameters:

Primary Substitution Criteria:

• Antenna Type: Whip, Straight configuration
• Termination: N Type connector
• Mounting Type: Connector mount
• Gain: 3dBi
• Applications: LoRa
• Frequency Compatibility: Overlap within operating bands

Substitution Logic:

The NBR-0041 qualifies as a direct substitute based on the following alignment:

1. Antenna Configuration: Both PIS-0382 and NBR-0041 employ whip, straight antenna geometry with identical N Type termination and connector mount configuration.

2. Gain Specification: Both parts specify 3dBi gain, ensuring equivalent RF performance characteristics.

3. Frequency Band Overlap: The NBR-0041 operates across 420MHz to 470MHz, which encompasses the 433MHz and 470MHz bands of the PIS-0382. This frequency range overlap permits functional substitution for applications utilizing these specific bands.

4. LoRa Application Compatibility: Both antennas are designated for LoRa applications, confirming functional equivalence within this use case.

5. Connector and Mounting Standardization: Identical N Type termination and connector mount configuration ensure mechanical and electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

For Applications Utilizing 433MHz or 470MHz Bands:

The NBR-0041 serves as a direct functional substitute for the obsolete PIS-0382 when system design is limited to the 433MHz or 470MHz frequency bands. The NBR-0041 maintains identical antenna geometry, gain specification, termination type, and mounting configuration. Both components carry identical MSL ratings and ECCN classification, ensuring compliance equivalence.

For Applications Requiring 868MHz, 915MHz, or 923MHz Bands:

The NBR-0041 does not provide frequency coverage for the 868MHz, 915MHz, or 923MHz bands specified in the PIS-0382. Alternative substitute components operating within these frequency ranges must be evaluated separately.

Product Status Consideration:

The PIS-0382 is classified as obsolete, while the NBR-0041 maintains active product status with confirmed inventory availability (857 Pcs). This status differential supports transition to the NBR-0041 for new designs and ongoing procurement requirements within compatible frequency bands.

Frequently Asked Questions (FAQ)

Q: Can the NBR-0041 replace the PIS-0382 in all applications?

A: The NBR-0041 provides functional substitution only for applications utilizing the 433MHz or 470MHz frequency bands. Applications requiring 868MHz, 915MHz, or 923MHz operation require alternative components. The NBR-0041 frequency range of 420MHz to 470MHz does not extend to the higher frequency bands supported by the PIS-0382.

Q: Are the connector types identical between PIS-0382 and NBR-0041?

A: Both components utilize N Type connectors with connector mount configuration, ensuring mechanical and electrical interchangeability at the termination interface.

Q: What is the significance of the different number of bands?

A: The PIS-0382 supports five frequency bands (433MHz, 470MHz, 868MHz, 915MHz, 923MHz), while the NBR-0041 operates as a single-band antenna centered at 445MHz with a range of 420MHz to 470MHz. Band count reflects the antenna's frequency coverage capability. Selection depends on the specific frequency bands required by the application.

Q: Do both antennas have identical gain specifications?

A: Both the PIS-0382 and NBR-0041 specify 3dBi gain, ensuring equivalent RF performance characteristics within their respective frequency ranges.

Q: What is the MSL rating, and are both parts equivalent?

A: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling. This specification is identical across both parts.

Q: Is the NBR-0041 available for procurement?

A: The NBR-0041 is listed as active product status with 857 Pcs in stock, confirming current availability for procurement and design implementation.

Q: Are there compliance or regulatory differences between the two parts?

A: Both components carry identical ECCN (EAR99) classification and MSL ratings. No compliance or regulatory differentiation exists between the PIS-0382 and NBR-0041.
