Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete C-3911 is based on functional equivalence within the RF antenna category for GPS applications. The primary substitute part, PCTEL 3917D, shares the following critical parameters that establish substitutability:

Key Substitution Parameters:

• Manufacturer: PCTEL, Inc. (same manufacturer)
• Application: GPS/GNSS navigation systems
• Mounting Type: Magnetic
• Termination: SMA Male connector
• Frequency Band: GPS L1 band (1.575GHz center frequency)
• Product Status: Active (currently manufactured and supported)

The 3917D represents an active production equivalent that maintains functional compatibility with GPS magnetic antenna applications while providing current manufacturing support and availability.

Engineering Selection Recommendations

For Obsolete Part Replacement:

The PCTEL 3917D is the designated substitute for the obsolete C-3911. Selection of the 3917D is based on the following engineering criteria:

1. Product Status: The 3917D maintains active production status, ensuring continued availability and manufacturer support, whereas the C-3911 is obsolete.

2. Regulatory Compliance: The 3917D is RoHS Compliant and carries current ECCN classification (7A994), meeting modern regulatory requirements for electronic components.

3. Functional Equivalence: Both components are GPS magnetic antennas manufactured by PCTEL, Inc., with identical mounting methodology (magnetic) and connector type (SMA Male).

4. Application Compatibility: The 3917D operates within the GPS L1 frequency band (1.575GHz center, 1.565GHz ~ 1.585GHz range), which is the standard frequency allocation for GPS receivers.

5. Environmental Rating: The 3917D provides IP67 ingress protection, suitable for outdoor and harsh environment GPS applications.

Frequently Asked Questions (FAQ)

Q: Can the 3917D directly replace the C-3911 in existing GPS antenna installations?

A: The 3917D is functionally equivalent to the C-3911 for GPS magnetic antenna applications. Both components use SMA Male termination and magnetic mounting. Compatibility depends on the specific system design and connector interface requirements of the host equipment.

Q: What is the primary reason for substituting the C-3911?

A: The C-3911 is classified as obsolete and no longer in active production. The 3917D is the active equivalent that provides continued manufacturer support and regulatory compliance.

Q: Are there any compliance differences between the C-3911 and 3917D?

A: The 3917D is RoHS Compliant with current ECCN classification (7A994). The C-3911 carries an obsolete ECCN designation. For applications requiring RoHS compliance or current export control compliance, the 3917D is the appropriate selection.

Q: What packaging options are available for the 3917D?

A: The 3917D is supplied in Bulk packaging format.

Q: Does the 3917D include any integrated components?

A: The 3917D includes a 3-meter cable, LNA (Low Noise Amplifier), and integrated filter as standard features.

Q: What is the physical size of the 3917D antenna?

A: The maximum height of the 3917D is 0.535 inches (13.60 millimeters).
