Amphenol SV Microwave 2985-6004-TD SMA Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol SV Microwave 2985-6004-TD is an SMA connector jack designed for RF coaxial applications. This female socket connector operates at 50 ohms impedance and is rated for frequencies up to 18 GHz. The connector features through-hole solder termination for PCB mounting and is constructed with stainless steel body and beryllium copper center contact, both finished in gold plating. The part is currently active in production with 717 units in stock. Equivalent substitute parts are necessary to address supply chain flexibility, alternative sourcing options, and procurement requirements across different manufacturers while maintaining identical electrical and mechanical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—the primary Amphenol SV Microwave 2985-6004-TD and the substitute options from Würth Elektronik and Samtec Inc.—are active production components with ROHS3 compliance certification. Selection between these parts should be based on the following engineering considerations:

Amphenol SV Microwave 2985-6004-TD is the original specification part with stainless steel body construction and beryllium copper center contact. This part is suitable for applications requiring the specified material composition and is available with 717 units in current inventory.

Würth Elektronik 60312002114503 provides full parametric equivalence with additional operational temperature specification (-65°C to 165°C) and voltage rating (335 V). The part features brass body construction and is packaged in trays with 1885 units available. REACH status indicates this part is affected by REACH regulations, requiring compliance verification for specific end-use applications.

Samtec Inc. SMA-J-P-H-ST-EM2 meets all critical electrical and mechanical parameters with gold-plated body finish and gold center contact plating. This part is available with 875 units in inventory and carries MSL Level 1 (Unlimited) moisture sensitivity rating. Specific material compositions for body and dielectric are not provided in the technical specification.

Selection should prioritize inventory availability, compliance requirements for the target application, and material specifications relevant to the end-use environment.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 60312002114503 be used as a direct replacement for the Amphenol SV Microwave 2985-6004-TD?

A: Yes. Both parts meet identical electrical specifications (50 ohms impedance, 18 GHz maximum frequency, SMA jack female socket configuration) and mechanical requirements (through-hole solder termination, threaded fastening, 500 mating cycles). The primary difference is body material composition (brass versus stainless steel) and the addition of operating temperature and voltage specifications on the Würth part.

Q: What is the significance of the different body materials between these connectors?

A: The Amphenol part uses stainless steel body construction while the Würth part uses brass. Both materials are suitable for RF coaxial connector applications and provide equivalent electrical performance at the specified frequency range. Material selection may be relevant for specific environmental conditions, corrosion resistance requirements, or mechanical durability considerations in the target application.

Q: Are there packaging differences between these substitute parts?

A: The Amphenol SV Microwave 2985-6004-TD packaging is not specified in the technical data. The Würth Elektronik 60312002114503 is supplied in trays with 1885 units available. The Samtec Inc. SMA-J-P-H-ST-EM2 is also supplied in trays with 875 units available. Packaging format should be verified against procurement and assembly requirements.

Q: What does ROHS3 compliance mean for these connectors?

A: ROHS3 compliance indicates that all three parts meet the Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials including lead, cadmium, mercury, and certain brominated flame retardants. This certification is required for many commercial and industrial applications, particularly in European markets.

Q: How does the Würth part's REACH status affect its use?

A: The Würth Elektronik 60312002114503 is listed as REACH Affected, meaning it contains substances of concern under the REACH regulation. The Amphenol part is listed as REACH Unaffected. Applications subject to REACH compliance requirements should verify that the Würth part meets specific end-use restrictions and documentation requirements for the target market and application.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) indicates the component's sensitivity to moisture during storage and handling. The Amphenol and Würth parts are listed as Not Applicable, indicating no moisture sensitivity concerns. The Samtec part carries MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions. This specification is relevant for storage conditions and assembly process requirements.

Q: Are there any frequency or impedance limitations when substituting these parts?

A: No. All three parts are rated for identical maximum frequency (18 GHz) and impedance (50 ohms). Substitution does not introduce frequency or impedance limitations within the specified operating range.
