Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 133-9701-231 are qualified based on strict electrical and mechanical parameter alignment. All identified substitutes maintain the following core requirements: MCX connector style, jack female socket configuration, 50 ohm impedance, solder contact and shield termination, through-hole mounting with snap-on fastening, 6 GHz maximum frequency operation, 500 mating cycles, beryllium copper center contact material, PTFE dielectric, gold plating on center contact and body finish, and gold housing color. Operating temperature range, voltage rating, body material composition, and compliance certifications may vary within acceptable engineering tolerances for this connector category. All substitutes are active production parts with RoHS3 compliance or equivalent regulatory status.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the 133-9701-231 across the core MCX jack female socket 50 ohm specification. Selection among substitutes is determined by application-specific operating temperature requirements and compliance certifications.

The 133-3701-231, 133-9701-201, and 133-9701-211 are direct Cinch Connectivity Solutions variants with identical operating temperature ranges (-65°C to 165°C) and full RoHS3 compliance with REACH affected status. These parts differ only in body material composition (brass, copper alloy, or copper) and are suitable for applications requiring the extended temperature envelope.

The 919-NM109J-51P from Amphenol RF operates within a narrower temperature range (-40°C to 155°C) and carries RoHS3 compliance with REACH affected status. This part is suitable for applications where the reduced temperature specification is acceptable.

The R113426097 from Radiall USA operates within the most restricted temperature range (-55°C to 125°C) and carries RoHS3 compliance. This part is packaged in box format rather than bulk and has not applicable MSL rating. Selection of this part is appropriate only when application temperature requirements fall within its specified operating range.

Frequently Asked Questions (FAQ)

Q: Can 133-3701-231 replace 133-9701-231 in all applications?

A: The 133-3701-231 maintains identical electrical specifications, operating temperature range, voltage rating, and mating cycle performance. The primary difference is body material composition (brass versus copper alloy). Both parts are RoHS3 compliant. Substitution is valid for applications where body material composition does not affect circuit performance or mechanical fit.

Q: What is the difference between the Cinch variants (133-9701-231, 133-9701-201, 133-9701-211)?

A: All three Cinch parts share the same base product number 133-9701 and maintain identical electrical and thermal specifications. Differences exist only in body material (copper alloy, copper alloy, or copper respectively) and RoHS compliance generation. All support the full -65°C to 165°C operating range.

Q: Is the Amphenol RF 919-NM109J-51P suitable for high-temperature applications?

A: The 919-NM109J-51P operates to 155°C maximum, which is 10°C below the 133-9701-231 specification. Applications requiring operation above 155°C must use the main part or Cinch variants. Applications with maximum operating temperature at or below 155°C can use this part.

Q: What are the packaging differences among substitute parts?

A: The 133-9701-231, 133-3701-231, 133-9701-201, 133-9701-211, and 919-NM109J-51P are supplied in bulk packaging. The R113426097 is supplied in box packaging. Packaging format does not affect electrical or mechanical performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The main part 133-9701-231 is RoHS compliant. All identified substitutes carry RoHS3 compliance certification. The 133-3701-231, 133-9701-201, 133-9701-211, and 919-NM109J-51P also carry REACH affected status. The R113426097 carries RoHS3 compliance with not applicable MSL rating.

Q: Can the R113426097 be used in applications requiring unlimited moisture sensitivity rating?

A: The R113426097 carries not applicable MSL rating, whereas the 133-9701-231 and most substitutes carry MSL 1 (unlimited) rating. Applications with specific moisture sensitivity requirements should use parts with MSL 1 rating. The R113426097 is suitable only when MSL rating is not a design constraint.
