Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for MCX connector receptacles is determined by strict equivalence across the following parameters:

Primary Equivalence Criteria:

• Connector style (MCX)
• Connector type (Receptacle, Female Socket)
• Impedance (50 Ohms)
• Mounting type (Through Hole)
• Contact and shield termination method (Solder)
• Frequency maximum rating (6 GHz minimum)
• Fastening type (Snap-On)
• Mating cycle rating (500 minimum)

Material and Construction Criteria:

• Center contact material (Beryllium Copper)
• Body material (Brass)
• Dielectric material (PTFE)
• Housing finish (Gold plating)

All substitute parts listed maintain these core parameters. Variations in operating temperature range, voltage rating, insertion loss specification, and packaging format do not affect functional interchangeability within the defined electrical and mechanical envelope.

Engineering Selection Recommendations

Amphenol RF 252105

Part 252105 is a direct parametric equivalent to the 252219. Both parts are manufactured by Amphenol RF, maintain active product status, and carry ROHS3 compliance certification. The primary distinction is packaging format: 252105 is supplied in bag packaging with significantly higher inventory availability (6400 units). This part is suitable for direct substitution in applications where packaging format does not impose constraints.

Amphenol RF 919-382J-51P

Part 919-382J-51P is manufactured by Amphenol RF and maintains active product status with ROHS3 compliance. This part features an extended operating temperature range (-65°C ~ 165°C) compared to the 252219 (-55°C ~ 155°C). Insertion loss specification is not provided for this part number. The 919-382J-51P is supplied in bulk packaging with 2884 units in stock. This part is suitable for applications requiring extended low-temperature performance.

TE Connectivity AMP Connectors 1330126-1

Part 1330126-1 is manufactured by TE Connectivity AMP Connectors and carries obsolete product status. This part features an extended operating temperature range (-65°C ~ 165°C) and elevated voltage rating (335 V) compared to the 252219. RoHS compliance is confirmed but specified as RoHS Compliant rather than ROHS3 Compliant. Due to obsolete status, this part should be selected only when existing design documentation or legacy system requirements mandate its use. Inventory availability is 2494 units.

Frequently Asked Questions (FAQ)

Q: Can Amphenol RF 252105 be used as a direct replacement for 252219?

A: Yes. Both parts maintain identical electrical and mechanical parameters across all critical substitution criteria: MCX receptacle configuration, 50 ohm impedance, through-hole solder termination, 6 GHz frequency rating, and snap-on fastening. The difference in packaging format (bag versus unspecified) does not affect functional performance. Both parts carry ROHS3 compliance certification.

Q: What is the primary advantage of selecting 919-382J-51P over 252219?

A: The 919-382J-51P provides an extended operating temperature range of -65°C ~ 165°C compared to the 252219 range of -55°C ~ 155°C. This extended range accommodates applications requiring operation at lower ambient temperatures. Both parts maintain identical impedance, frequency rating, and termination specifications.

Q: Why is 1330126-1 listed as obsolete?

A: The 1330126-1 carries obsolete product status as indicated in the manufacturer data. This designation reflects that the part is no longer in active production. While functional equivalence is maintained, obsolete parts present supply chain risk and should be selected only when legacy system requirements or existing design documentation specifically mandate their use.

Q: Are there packaging differences between these substitute parts?

A: Yes. The 252219 packaging format is not specified. The 252105 is supplied in bag packaging. Both 919-382J-51P and 1330126-1 are supplied in bulk packaging. Packaging format affects handling, storage, and inventory management but does not alter electrical or mechanical performance.

Q: Do all substitute parts carry the same compliance certifications?

A: The 252219, 252105, and 919-382J-51P all carry ROHS3 Compliant certification. The 1330126-1 carries RoHS Compliant certification. All four parts are REACH Affected and carry EAR99 ECCN classification. Compliance status should be verified against specific application requirements.

Q: What is the inventory status for each part?

A: Current inventory levels are: 252219 (728 units), 252105 (6400 units), 919-382J-51P (2884 units), and 1330126-1 (2494 units). The 252105 offers the highest inventory availability.
