Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 082-4336 is based on strict electrical and mechanical parameter alignment. The primary substitute, Amphenol RF 172176, maintains equivalence through the following critical parameters:

Electrical Equivalence Criteria:

• Identical impedance specification: 50 Ohms
• Matching frequency maximum: 11 GHz
• Equivalent insertion loss: 0.15 dB
• Identical voltage rating: 1500 V
• Matching mating cycle rating: 500 cycles

Mechanical Equivalence Criteria:

• Identical connector style: N Type
• Identical connector type: Plug, Male Pin
• Identical contact termination method: Solder
• Identical shield termination method: Crimp
• Identical fastening type: Threaded
• Compatible cable group support: RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, 393

Compliance Equivalence:

• Matching operating temperature range: -65°C to 165°C
• RoHS compliance maintained (RoHS3 Compliant for substitute)
• Moisture sensitivity level: 1 (Unlimited)

The 172176 substitute differs in mounting configuration (right angle vs. straight), housing finish (white bronze vs. silver), and center contact material (beryllium copper vs. brass), but these variations do not affect electrical performance or core functional compatibility for standard N Type plug applications.

Engineering Selection Recommendations

Primary Substitute: Amphenol RF 172176

The 172176 is the designated substitute for the obsolete 082-4336 based on complete electrical and mechanical parameter alignment. Selection of this substitute is supported by:

1. Product Status: The 172176 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity.

2. Compliance Certification: The 172176 carries ROHS3 compliance, exceeding the RoHS compliance of the original part and meeting current regulatory requirements.

3. Electrical Performance: All critical electrical parameters are identical, including impedance, frequency response, insertion loss, voltage rating, and mating cycle specifications.

4. Mechanical Compatibility: The connector maintains N Type plug configuration with solder contact termination and crimp shield termination, ensuring compatibility with existing cable assemblies and termination procedures.

5. Environmental Specifications: Operating temperature range and moisture sensitivity level remain unchanged, preserving thermal and environmental performance characteristics.

Mounting Configuration Consideration: The 172176 features right-angle mounting versus the straight configuration of the 082-4336. Physical space constraints and cable routing requirements must be evaluated during integration planning.

Material Differences: The substitute incorporates beryllium copper center contacts and white bronze body finish. These material changes enhance durability and environmental resistance without affecting electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 172176 directly replace the 082-4336 in existing assemblies?

A: Electrical and functional replacement is direct. Physical mounting orientation differs due to right-angle configuration. Cable routing and connector positioning must be assessed for mechanical fit within the application.

Q: Are the solder termination procedures identical between the two parts?

A: Both parts utilize solder contact termination and crimp shield termination. Standard N Type connector soldering procedures apply to both components without modification.

Q: What is the significance of the beryllium copper center contact in the 172176?

A: Beryllium copper provides enhanced mechanical durability and improved contact resistance stability compared to brass. This material change does not alter electrical performance but extends component service life.

Q: Does the weatherproof ingress protection of the 172176 affect compatibility?

A: The weatherproof rating of the 172176 is an enhancement that does not restrict compatibility. Applications not requiring weatherproofing are unaffected by this specification.

Q: Are both parts compatible with the same cable groups?

A: Yes. Both the 082-4336 and 172176 support identical cable group compatibility: RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, and 393.

Q: What is the inventory status for procurement planning?

A: The 082-4336 (obsolete) has 732 pieces in stock. The 172176 (active) has 833 pieces in stock. Procurement should transition to the 172176 for new designs and ongoing requirements.

Q: Do the RoHS compliance levels affect substitution eligibility?

A: The 172176 ROHS3 compliance exceeds the RoHS compliance of the 082-4336, ensuring compatibility with current and future regulatory requirements.

Q: Is the packaging format different between the two parts?

A: The 082-4336 packaging is not specified. The 172176 is supplied in bag packaging and includes 3 pieces: 1 connector, 1 end cap, and 1 ferrule.
