Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5-1814832-2

The TE Connectivity 5-1814832-2 is the direct upgrade path for the obsolete 5-1814832-1. Both components share the same base product number (1814832) and are from the same ZDC/Greenpar series. The 5-1814832-2 is currently in active production status, ensuring long-term availability. This part maintains all core electrical and mechanical specifications while offering enhanced frequency capability (6 GHz versus 3 GHz). The 5-1814832-2 is ROHS3 compliant and REACH affected, matching the regulatory profile of the original component. Mating cycle rating remains at 500 cycles. This substitute is the preferred selection for direct replacement in existing designs.

Alternative Substitute: Amphenol RF 901-10112

The Amphenol RF 901-10112 provides an alternative from a different manufacturer while maintaining all critical SMA jack specifications. This part is active in production and ROHS3 compliant. The 901-10112 operates to 4 GHz, exceeding the original 3 GHz specification. The primary design difference is the body material (brass versus zinc alloy) and reduced mating cycle rating (200 cycles versus 500 cycles). This substitute is suitable for applications where the lower mating cycle count is acceptable and where supply chain diversification is beneficial.

Alternative Substitute: Adam Tech RF2-19A-T-00-50-G

The Adam Tech RF2-19A-T-00-50-G offers the highest frequency capability (18 GHz) among available substitutes, making it suitable for applications requiring extended frequency performance. This part is active in production and ROHS3 compliant. The RF2-19A-T-00-50-G is REACH unaffected, which may provide regulatory advantages in certain supply chain scenarios. The housing color is white rather than gold, which is a cosmetic difference. Voltage rating is 335 V, which is lower than the original 500 V specification. Mating cycle information is not provided for this part.

Regulatory Compliance:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage practices. The TE Connectivity 5-1814832-2 and Amphenol RF 901-10112 are REACH affected, matching the original part's regulatory status. The Adam Tech RF2-19A-T-00-50-G is REACH unaffected, which may simplify compliance documentation in certain jurisdictions.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-1814832-2 be used as a direct replacement for the 5-1814832-1?

A: Yes. The 5-1814832-2 maintains all core electrical and mechanical specifications required for direct substitution. Both parts are SMA female socket connectors with 50 ohm impedance, through-hole solder termination, and identical operating temperature ranges. The 5-1814832-2 is the active production equivalent and is the recommended replacement path.

Q: What is the significance of the frequency rating difference between the main part (3 GHz) and the substitutes (4 GHz to 18 GHz)?

A: The frequency rating indicates the maximum operating frequency for which the connector is specified. Substitutes with higher frequency ratings (4 GHz, 6 GHz, 18 GHz) are backward compatible with applications designed for 3 GHz operation. A higher frequency rating does not negatively affect performance at lower frequencies. Selection of a higher-frequency substitute provides design margin and future-proofing without compromising compatibility.

Q: Are there differences in mating cycle ratings among the substitutes?

A: Yes. The main part and TE Connectivity 5-1814832-2 are rated for 500 mating cycles. The Amphenol RF 901-10112 is rated for 200 mating cycles. The Adam Tech RF2-19A-T-00-50-G does not specify a mating cycle rating. For applications requiring frequent connector engagement and disengagement, the 500-cycle rated parts (5-1814832-1 or 5-1814832-2) are preferred. For applications with infrequent mating, the 200-cycle rated part is acceptable.

Q: What is the difference between the center contact materials used in these connectors?

A: The main part uses Phosphor Bronze, the TE Connectivity 5-1814832-2 uses Beryllium Copper, the Amphenol RF 901-10112 uses Phosphor Bronze, and the Adam Tech RF2-19A-T-00-50-G uses Brass. These materials are all acceptable for 50 ohm SMA connectors and provide equivalent electrical performance. Material selection affects mechanical properties such as spring force and wear characteristics but does not alter the electrical impedance or frequency response.

Q: Does the housing color difference (gold versus white) affect connector performance?

A: No. Housing color is a cosmetic specification and does not affect electrical performance, impedance, or frequency response. The Adam Tech RF2-19A-T-00-50-G features a white housing while other substitutes feature gold housing. This difference is purely visual and does not impact functional compatibility.

Q: What is the significance of the voltage rating difference between the main part (500 V) and some substitutes (335 V)?

A: Voltage rating indicates the maximum voltage the connector can safely withstand. The main part is rated for 500 V, while the TE Connectivity 5-1814832-2 and Adam Tech RF2-19A-T-00-50-G are rated for 335 V. For applications operating below 335 V, all substitutes are acceptable. For applications requiring the full 500 V rating, the main part or Amphenol RF 901-10112 (voltage rating not specified) should be selected.

Q: How do packaging differences (Cut Tape versus Bulk) affect component selection?

A: Packaging format affects handling, storage, and automated assembly processes but does not affect component performance. The TE Connectivity 5-1814832-2 is supplied in Cut Tape (CT) packaging, while the Amphenol RF 901-10112 and Adam Tech RF2-19A-T-00-50-G are supplied in Bulk packaging. Selection between packaging formats depends on manufacturing process requirements and inventory management practices.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the original 5-1814832-1. This ensures compatibility with manufacturing processes and regulatory requirements in regions requiring ROHS compliance.

Q: What is the difference between REACH Affected and REACH Unaffected status?

A: REACH Affected indicates the component or its materials are subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. REACH Unaffected indicates the component is not subject to these regulations. The TE Connectivity 5-1814832-2 and Amphenol RF 901-10112 are REACH Affected, matching the original part. The Adam Tech RF2-19A-T-00-50-G is REACH Unaffected, which may simplify compliance documentation in certain supply chain scenarios.

Q: Which substitute part should be selected for new designs?

A: For new designs, the TE Connectivity 5-1814832-2 is the recommended selection. It is the active production equivalent from the same manufacturer and series, ensuring long-term availability and design continuity. The 5-1814832-2 offers enhanced frequency capability (6 GHz) while maintaining all core specifications of the original part.
