Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Cinch Connectivity Solutions 133-3701-211

The 133-3701-211 is the direct functional equivalent to the Pomona Electronics 73007. This part maintains identical core specifications while offering enhanced performance margins. It is currently in active production status, ensuring long-term availability and supply chain stability. The part carries ROHS3 compliance and REACH Affected designation, meeting current regulatory requirements.

Alternative Selections Based on Application Requirements:

For Gold-Finish Applications (Corrosion Resistance):

• 133-3701-211 (Brass body, Gold finish)
• 133-9701-201 (Copper Alloy body, Gold finish, Non-Magnetic)
• 133-9701-211 (Copper body, Gold finish, Non-Magnetic)

For Nickel-Finish Applications (Cost Optimization):

• 133-3701-206 (Brass body, Nickel finish)
• 133-3701-216 (Brass body, Nickel finish)

For Non-Magnetic Applications:

• 133-9701-201 (Copper Alloy body)
• 133-9701-211 (Copper body)

All substitute parts exceed the original specification in frequency capability (6 GHz vs. 3 GHz), operating temperature range (-65°C to 165°C vs. -55°C to 155°C), and voltage rating (335 V vs. 170 V), providing enhanced performance headroom for system designs.

Frequently Asked Questions (FAQ)

Q: Can I use Cinch 133-3701-211 as a direct replacement for Pomona 73007?

A: Yes. The 133-3701-211 meets all core electrical and mechanical specifications of the Pomona 73007. Both are MCX female socket receptacles with 50-ohm impedance, solder termination, through-hole mounting, and snap-on fastening. The Cinch part is currently in active production, addressing the obsolescence of the original Pomona part.

Q: What is the difference between the gold-finish and nickel-finish variants?

A: The primary difference is body finish material. Gold-finish parts (133-3701-211, 133-9701-201, 133-9701-211) provide enhanced corrosion resistance and are typically specified for high-reliability applications. Nickel-finish parts (133-3701-206, 133-3701-216) offer cost optimization while maintaining electrical performance. Both finishes maintain the same electrical characteristics and impedance.

Q: Why do some substitute parts have higher frequency ratings (6 GHz vs. 3 GHz)?

A: The substitute parts are engineered to support higher frequency operation while maintaining backward compatibility with 3 GHz applications. The higher frequency capability provides design margin and future-proofing for system upgrades without requiring connector replacement.

Q: Are the non-magnetic variants (133-9701-201, 133-9701-211) compatible with standard MCX applications?

A: Yes. The non-magnetic designation indicates the body material composition (Copper Alloy or Copper) rather than a functional difference. These parts maintain identical electrical specifications and are fully compatible with standard MCX receptacle applications. The non-magnetic property is beneficial in applications sensitive to magnetic field interference.

Q: What is the difference between Brass, Copper Alloy, and Copper body materials?

A: All three materials provide equivalent electrical performance and impedance characteristics. Brass (133-3701 series) is the standard material. Copper Alloy (133-9701-201) and Copper (133-9701-211) bodies offer alternative material compositions that may be specified for specific manufacturing processes or supply chain requirements. Material selection does not affect connector functionality or RF performance.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Most substitute parts are ROHS3 compliant. The exception is 133-3701-206, which carries RoHS Compliant designation without the "3" specification. For applications requiring strict ROHS3 compliance, select from 133-3701-211, 133-3701-201, 133-3701-216, 133-9701-201, or 133-9701-211.

Q: What is the REACH status of these substitute parts?

A: Most substitute parts carry REACH Affected designation (133-3701-211, 133-3701-201, 133-3701-216, 133-9701-201, 133-9701-211), indicating they are subject to REACH regulations. The 133-3701-206 does not specify REACH status in the provided data. Verify REACH compliance requirements for your specific application and regulatory jurisdiction.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels vary across substitute parts. 133-3701-211 has 8,227 units in stock, providing strong availability. 133-9701-211 has 2,511 units, 133-3701-216 has 1,799 units, 133-3701-201 has 5,551 units, 133-9701-201 has 840 units, and 133-3701-206 has 704 units. For high-volume requirements, 133-3701-211 or 133-3701-201 are recommended.
