Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 252220 are identified based on strict parametric equivalence across the following critical criteria:

Electrical Parameters: Impedance (50 Ohms), frequency rating (6 GHz maximum), voltage rating (225 V), insertion loss (0.1 dB), and mating cycle rating (500 cycles) must match exactly.

Mechanical Parameters: Connector style (MCX), connector type (receptacle, female socket), mounting configuration (through-hole, right-angle), contact termination method (solder), and shield termination method (solder) must be identical.

Material & Finish Specifications: Center contact material (beryllium copper), body material (brass), body finish (gold), center contact plating (gold), and dielectric material (PTFE) must correspond.

Compliance & Environmental: RoHS3 compliance status, MSL rating (1 - Unlimited), REACH affected status, and ECCN classification (EAR99) must align. Operating temperature ranges may vary within acceptable industrial limits.

Number of Ports: Single port (1) configuration required.

The substitute parts 252129 and 919-119J-51AX meet all mandatory electrical and mechanical equivalence criteria, with documented inventory availability and identical product status classification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—252220, 252129, and 919-119J-51AX—are classified as Active product status and carry ROHS3 compliance certification. They are functionally equivalent MCX receptacle connectors with identical electrical specifications for 50-ohm RF applications up to 6 GHz.

Part 252220 operates within the temperature range of -55°C to 155°C and is available in 907 units of current inventory.

Part 252129 is supplied in bag packaging with 2023 units in stock. Operating temperature specification is not provided in the available data. This part is suitable for applications where packaging format and inventory availability are primary selection factors.

Part 919-119J-51AX offers an extended operating temperature range of -65°C to 165°C and is supplied in bulk packaging with 1142 units available. This part is appropriate for applications requiring wider temperature performance margins.

Selection between these three parts should be based on packaging requirements, inventory availability, and operating temperature envelope specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can part 252129 be used as a direct replacement for part 252220?

A: Yes. Both parts are MCX receptacle connectors with identical electrical parameters (50 ohms, 6 GHz maximum frequency, 0.1 dB insertion loss, 225 V rating, 500 mating cycles). Material composition, termination methods, and compliance certifications are equivalent. The primary difference is packaging format (bag versus unspecified) and inventory quantity.

Q: What is the difference between part 919-119J-51AX and the other two substitutes?

A: Part 919-119J-51AX maintains all electrical and mechanical equivalence with parts 252220 and 252129. The distinguishing factor is the extended operating temperature range (-65°C to 165°C versus -55°C to 155°C for part 252220). This part is supplied in bulk packaging and has a different base product number (91911 versus 2522 or 2521).

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts carry ROHS3 compliance certification and are classified as REACH Affected with EAR99 ECCN designation.

Q: What packaging options are available for these MCX connectors?

A: Part 252220 packaging is not specified in the available data. Part 252129 is supplied in bag packaging. Part 919-119J-51AX is supplied in bulk packaging. Packaging selection should align with assembly process requirements and inventory management protocols.

Q: Are there any operating temperature limitations when selecting a substitute?

A: Part 252220 operates from -55°C to 155°C. Part 252129 does not have a specified operating temperature range in the available documentation. Part 919-119J-51AX operates from -65°C to 165°C. Applications requiring operation below -55°C or above 155°C should specify part 919-119J-51AX.

Q: Do all parts have the same mating cycle rating?

A: Yes. All three parts are rated for 500 mating cycles, indicating equivalent mechanical durability and connector longevity specifications.

Q: What is the insertion loss specification for these connectors?

A: All three parts have an insertion loss specification of 0.1 dB at the maximum frequency rating of 6 GHz, ensuring consistent RF performance across all substitute options.
