Key Parameters

Substitute Part Grouping Explanation

The 142-1711-001 qualifies as a parametric equivalent to the 142-1711-021 based on the following critical parameters that determine substitutability:

• Connector style and type (SMA jack, female socket)
• Electrical impedance (50 ohms)
• Mounting configuration (panel mount, right angle with flange)
• Termination method (solder for both center contact and shield)
• Frequency capability (18 GHz maximum)
• Operating temperature range (-65°C to 165°C)
• Voltage rating (335 V)
• Mating cycle rating (500 cycles)
• Dielectric material (PTFE)
• Center contact material (beryllium copper)
• Body material and finish (brass with gold plating)

Both parts share the same base product number (142-1711), confirming their functional equivalence within the SMA connector jack series.

Parameter Comparison

Engineering Selection Recommendations

Both the 142-1711-021 and 142-1711-001 are active production parts with identical electrical and mechanical specifications.

Both parts maintain MSL Level 1 (unlimited moisture sensitivity), indicating no special storage or handling requirements. Selection between these parts should be based on compliance requirements specific to the end application and regional regulations. The 142-1711-001 offers higher current inventory availability at 1310 units compared to 997 units for the 142-1711-021.

Frequently Asked Questions (FAQ)

Q: Can the 142-1711-001 be used as a direct replacement for the 142-1711-021?

A: Yes. Both parts are parametrically equivalent SMA connector jacks with identical electrical impedance (50 ohms), frequency capability (18 GHz), operating temperature range (-65°C to 165°C), and mechanical mounting configuration (panel mount, right angle, solder termination). They share the same base product number (142-1711) and are interchangeable in RF circuit applications.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the third iteration of the Restriction of Hazardous Substances directive with updated substance restrictions. The 142-1711-001 carries ROHS3 certification, while the 142-1711-021 carries standard RoHS compliance. Both certifications restrict hazardous materials, with ROHS3 representing the more current regulatory standard.

Q: Does REACH Affected status on the 142-1711-001 affect its use?

A: REACH Affected status indicates the part contains substances subject to the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation. This is a regulatory classification that does not affect the electrical or mechanical performance of the connector. Selection should be based on end-use application location and applicable regional regulations.

Q: Are there any packaging or inventory considerations when selecting between these parts?

A: Both parts are supplied in bulk packaging. The 142-1711-001 has higher current inventory availability (1310 units) compared to the 142-1711-021 (997 units). For applications requiring immediate availability, the 142-1711-001 may offer supply chain advantages.

Q: What is the MSL Level 1 rating and does it affect storage?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling. Both parts can be stored under standard conditions without desiccant packaging or controlled humidity environments.
