Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the PDQ24499-91NF are determined by the following critical parameters:

Parametric Equivalent Classification: The PDQ24499-91FNF qualifies as a parametric equivalent based on identical specifications across all functional parameters: frequency bands (2.4GHz, 5.4GHz), frequency range (2.4GHz ~ 2.5GHz, 4.9GHz ~ 5.95GHz), antenna type (Panel), gain values (8.6dBi, 9.4dBi), VSWR (1.6, 1.8), termination (N Type Female), power rating (10 W), mounting type (Bracket Mount), ingress protection (IP67), and physical dimensions (41.00mm height). The primary distinction is product status: PDQ24499-91FNF is Active, whereas PDQ24499-91NF is Obsolete.

Similar Part Classification: The OMB.8912.05F21 manufactured by Taoglas Limited is classified as a similar part rather than a direct equivalent. While both components share N Type Female termination and bracket mounting, they differ fundamentally in antenna type (Whip, Straight vs. Panel), frequency bands (850MHz, 900MHz, 1.8MHz, 1.9GHz, 2.1GHz vs. 2.4GHz, 5.4GHz), frequency range (824MHz ~ 960MHz, 1.71GHz ~ 2.17GHz vs. 2.4GHz ~ 2.5GHz, 4.9GHz ~ 5.95GHz), gain characteristics (3.04dBi to 5.56dBi vs. 8.6dBi to 9.4dBi), and power rating (50 W vs. 10 W). This part is suitable only for applications requiring cellular and ISM band coverage, not Wi-Fi applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Wi-Fi Applications):

The PDQ24499-91FNF is the appropriate selection for direct replacement of the obsolete PDQ24499-91NF. Both components maintain identical electrical and mechanical specifications, including frequency bands, gain characteristics, VSWR performance, termination type, and physical dimensions. The PDQ24499-91FNF carries Active product status and maintains RoHS compliance, ensuring long-term availability and regulatory alignment. Current inventory availability is 1,099 pieces.

For Alternative Applications (Non-Wi-Fi):

The OMB.8912.05F21 is not suitable as a substitute for Wi-Fi applications due to fundamental frequency band incompatibility. This component operates in cellular and ISM bands (850MHz through 2.17GHz) and is designed for DCS, GSM, PCS, and WCDMA applications. Selection of this part would require complete system redesign and is applicable only to cellular or general ISM band implementations.

Compliance Considerations:

Both the PDQ24499-91FNF and PDQ24499-91NF maintain RoHS compliance status. The PDQ24499-91FNF carries ECCN classification EAR99, while the original part carries ECCN 5A991G. The OMB.8912.05F21 carries ECCN EAR99 and ROHS3 compliance with REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can PDQ24499-91FNF be used as a direct replacement for PDQ24499-91NF?

A: Yes. The PDQ24499-91FNF is a parametric equivalent with identical electrical and mechanical specifications. All frequency bands, gain values, VSWR performance, termination types, mounting configurations, and physical dimensions are identical. The primary difference is product status: PDQ24499-91FNF is Active while PDQ24499-91NF is Obsolete.

Q: What is the difference between the PDQ24499-91NF and PDQ24499-91FNF part numbers?

A: The part numbers differ by a single character designation (91NF vs. 91FNF). This designation change reflects the transition from Obsolete to Active product status. All functional parameters remain unchanged.

Q: Is OMB.8912.05F21 compatible with PDQ24499-91NF applications?

A: No. The OMB.8912.05F21 operates in different frequency bands (850MHz through 2.17GHz) and is designed for cellular and ISM applications, not Wi-Fi. Substitution would require complete system redesign and is not applicable to existing Wi-Fi implementations.

Q: What are the key parameters that determine substitution eligibility?

A: For Wi-Fi antenna substitution, the critical parameters are: frequency bands (2.4GHz and 5.4GHz), frequency range (2.4GHz ~ 2.5GHz, 4.9GHz ~ 5.95GHz), antenna type (Panel), gain values (8.6dBi and 9.4dBi), VSWR (1.6 and 1.8), termination type (N Type Female), power rating (10 W), mounting type (Bracket Mount), and physical dimensions (41.00mm height).

Q: Are there inventory considerations for part selection?

A: Current inventory for PDQ24499-91FNF is 1,099 pieces (Active status), compared to 721 pieces for PDQ24499-91NF (Obsolete status). The Active status of PDQ24499-91FNF ensures continued availability for future procurement cycles.

Q: What compliance certifications apply to these parts?

A: PDQ24499-91NF and PDQ24499-91FNF both carry RoHS Compliance certification. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both parts. The OMB.8912.05F21 carries ROHS3 Compliance with REACH Unaffected status.
