Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent Substitutes (PIS-0386, PIS-0387, PIS-0390, PIS-0392, PIS-0394):

These five parts are direct parametric equivalents to PIS-0391. All components share identical electrical and mechanical specifications across frequency range, center frequency, antenna type, gain, termination, mounting configuration, height, power rating, and frequency group classification. All are classified as obsolete products with identical MSL ratings. Selection among these equivalents may be based on inventory availability or specific connector interface requirements not differentiated in the provided parameters.

Alternative Frequency Band Substitute (NBR-0043):

NBR-0043 operates in the 420MHz to 470MHz frequency range with a 445MHz center frequency, representing a different ISM band allocation. This part maintains equivalent antenna type, gain, termination, power rating, and MSL specifications. NBR-0043 is classified as an active product with ROHS3 compliance certification. This component is suitable only for applications requiring operation in the 420MHz to 470MHz band and is not interchangeable with PIS-0391 for 860MHz to 930MHz band applications.

Frequently Asked Questions (FAQ)

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

A: Yes. These five parts are parametric equivalents with identical frequency range (860MHz ~ 930MHz), center frequency (895MHz), antenna type (whip, straight), gain (5.8dBi), termination (N Type Male), mounting type (bracket mount), height (31.496" / 800.00mm), power rating (20 W), and all other specified electrical and mechanical parameters.

Q: Is NBR-0043 a suitable replacement for PIS-0391?

A: NBR-0043 is not suitable for direct replacement in applications requiring 860MHz to 930MHz operation. NBR-0043 operates in the 420MHz to 470MHz frequency band. This part is only applicable for systems designed for the 420MHz to 470MHz ISM band allocation.

Q: What is the difference between the parametric equivalent parts?

A: The provided parameters do not specify differences between PIS-0386, PIS-0387, PIS-0390, PIS-0392, and PIS-0394. All five parts share identical electrical and mechanical specifications. Differences may exist in connector interface designations or other characteristics not included in the provided parameter set.

Q: Why is PIS-0391 listed as obsolete?

A: PIS-0391 is classified as obsolete in the product status field. The parametric equivalent parts (PIS-0386, PIS-0387, PIS-0390, PIS-0392, PIS-0394) are also classified as obsolete. NBR-0043 is the only active product in the substitute list.

Q: Are there compliance or certification differences between these parts?

A: NBR-0043 is specified as ROHS3 compliant. Compliance information is not provided for PIS-0391 or the other parametric equivalents. All parts share identical ECCN (EAR99) and HTSUS classifications where specified.

Q: What mounting configurations are available?

A: PIS-0391 and all parametric equivalents feature bracket mount configuration. NBR-0043 features bracket and connector mount configuration, providing additional mounting flexibility.

Q: Are all substitute parts rated for the same power levels?

A: Yes. All substitute parts, including PIS-0391, are rated for a maximum power of 20 W.
