Substitute Part Grouping Explanation

Substitute parts for PIS-0387 are grouped based on strict parametric equivalence across the following critical parameters:

Primary Equivalence Criteria:

Frequency Range: 860MHz ~ 930MHz
Center Frequency: 895MHz
Antenna Type: Whip, Straight
Gain: 5.8dBi
Termination: N Type Male
Mounting Type: Bracket Mount
Power - Max: 20W
Height (Max): 31.496" (800.00mm)
RF Family/Standard: General ISM
Frequency Group: UHF (300MHz ~ 1GHz)
Applications: LoRa
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed (PIS-0394, PIS-0386, PIS-0391, PIS-0392, PIS-0390) maintain identical electrical and mechanical specifications to the main part PIS-0387. These parts are interchangeable from an engineering standpoint based on the provided parameters.

Secondary Consideration: NBR-0043 operates in a different frequency band (420MHz ~ 470MHz, center 445MHz) and therefore represents a frequency-specific alternative rather than a direct parametric equivalent.

Engineering Selection Recommendations

Direct Substitutes (860MHz ~ 930MHz Band):

Parts PIS-0386, PIS-0390, PIS-0391, PIS-0392, and PIS-0394 are direct parametric equivalents to PIS-0387. All five substitute parts maintain identical electrical specifications (frequency range, gain, power rating, termination type) and mechanical specifications (antenna type, mounting configuration, physical height). All are classified as obsolete with equivalent product status.

Frequency-Specific Alternative (420MHz ~ 470MHz Band):

NBR-0043 is an active product that maintains identical gain (5.8dBi), termination type (N Type Male), antenna type (Whip, Straight), and power rating (20W). However, NBR-0043 operates in the 420MHz to 470MHz frequency band with a center frequency of 445MHz, making it suitable only for applications requiring operation in this lower UHF band. NBR-0043 features RoHS3 compliance and a reduced physical height of 19.685" (500.00mm) compared to the 31.496" (800.00mm) of PIS-0387. NBR-0043 mounting configuration includes both bracket and connector mount options.

Compliance Considerations:

All listed parts carry ECCN EAR99 classification and are subject to the same export control framework. MSL rating of 1 (Unlimited) applies uniformly across all parts, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can PIS-0386, PIS-0390, PIS-0391, PIS-0392, and PIS-0394 be used interchangeably with PIS-0387?

A: Yes. These five parts are parametric equivalents with identical frequency range (860MHz ~ 930MHz), gain (5.8dBi), termination (N Type Male), mounting type (Bracket Mount), power rating (20W), and physical dimensions (31.496" height). All are classified as obsolete.

Q: What is the key difference between the 860MHz ~ 930MHz band parts and NBR-0043?

A: NBR-0043 operates in the 420MHz ~ 470MHz frequency band, making it suitable only for applications requiring operation in this lower frequency range. While it maintains the same gain (5.8dBi) and termination type (N Type Male), the frequency incompatibility restricts its use to systems designed for the 445MHz center frequency. Additionally, NBR-0043 is an active product with RoHS3 compliance and features a shorter physical height (19.685" versus 31.496").

Q: Are there mounting compatibility differences between substitute parts?

A: PIS-0387, PIS-0386, PIS-0390, PIS-0391, PIS-0392, and PIS-0394 all use Bracket Mount configuration. NBR-0043 offers both Bracket and Connector Mount options, providing additional mounting flexibility for applications requiring connector-based installation.

Q: What is the inventory status of substitute parts?

A: PIS-0394 has 1074 units in stock, PIS-0392 has 1064 units, PIS-0387 has 1081 units, PIS-0390 has 1005 units, PIS-0386 has 940 units, PIS-0391 has 747 units, and NBR-0043 has 1200 units in stock.

Q: Are all parts subject to the same export control classification?

A: Yes. All listed parts carry ECCN EAR99 classification, indicating they are subject to the same export control framework and regulatory requirements.

Q: What is the moisture sensitivity level for these antennas?

A: All parts maintain MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or operation.
