Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on parametric equivalence and mounting configuration:

Engineering Selection Recommendations

Direct Substitutes (No Design Modification Required):

The following parts maintain identical board edge, surface mount configuration and are suitable for direct substitution:

908-22100 (Amphenol RF) is a parametric equivalent from the same manufacturer with identical mounting and electrical specifications. This part provides the highest compatibility assurance.

135-3711-801 (Cinch Connectivity Solutions) is a parametric equivalent with board edge, surface mount configuration. This part maintains all critical electrical parameters and mounting requirements.

135-9711-801 (Cinch Connectivity Solutions) is a similar part with board edge, surface mount configuration. Body material differs (Copper Alloy versus Brass) but maintains all electrical and mechanical parameters.

82_MMCX-S50-0-2/111_KE (Huber+Suhner, Inc.) is a parametric equivalent with board edge, surface mount configuration. Dielectric material includes both PFA and PTFE. REACH status differs (Unaffected versus Affected).

MCSF96GT-T/R (Lighthorse Technologies, Inc) is a parametric equivalent with board edge, surface mount configuration. Operating temperature range extends to -65°C ~ 165°C. RoHS compliance status differs (RoHS Compliant versus ROHS3 Compliant).

R110422100 (Radiall USA, Inc.) is a parametric equivalent with board edge, surface mount configuration. All critical electrical and mechanical parameters are maintained.

Alternative Substitutes (PCB Design Modification Required):

135-3701-201 and 135-3701-211 (Cinch Connectivity Solutions) feature through-hole mounting instead of board edge, surface mount configuration. These parts require PCB redesign and are suitable only when board layout modification is feasible.

All substitute parts maintain ROHS3 or RoHS compliance status and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can 908-22100 be used as a direct replacement for 908-22103?

A: Yes. Both parts are manufactured by Amphenol RF, share identical connector style (MMCX), connector type (Jack, Female Socket), impedance (50 Ohms), mounting type (Board Edge, Cutout; Surface Mount), frequency rating (6 GHz), and termination methods (Solder). The 908-22100 includes specified operating temperature range (-65°C ~ 165°C) while the 908-22103 does not specify this parameter.

Q: What is the difference between board edge, surface mount and through-hole mounting?

A: Board edge, surface mount connectors are soldered directly to the edge of the PCB with the connector body mounted on the surface. Through-hole connectors require holes drilled through the PCB for pin insertion. These mounting types are not interchangeable without PCB redesign.

Q: Are the Cinch Connectivity Solutions parts (135-3711-801, 135-9711-801) suitable replacements?

A: Yes, for board edge, surface mount applications. Both parts maintain the required MMCX connector style, 50 Ohm impedance, 6 GHz frequency rating, and snap-on fastening. 135-3711-801 uses Brass body material identical to the main part. 135-9711-801 uses Copper Alloy body material but maintains all electrical specifications.

Q: What does REACH Affected versus REACH Unaffected mean?

A: REACH Affected indicates the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. REACH Unaffected indicates the part does not contain regulated substances. Both statuses are compliant; the designation indicates regulatory classification only.

Q: Can I use MCSF96GT-T/R if my application requires -65°C operation?

A: Yes. MCSF96GT-T/R specifies operating temperature range of -65°C ~ 165°C, which covers the lower temperature requirement. This part maintains all other critical electrical and mechanical parameters.

Q: What is the significance of the 500 mating cycles specification?

A: The 500 mating cycles specification indicates the connector is rated for 500 connect/disconnect cycles before performance degradation. All listed substitute parts maintain this same rating, ensuring equivalent mechanical durability.

Q: Does body material (Brass versus Copper Alloy) affect electrical performance?

A: No. Both Brass and Copper Alloy body materials maintain the required 50 Ohm impedance and electrical characteristics. Body material selection affects mechanical properties and corrosion resistance but not RF performance for these connector types.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are either ROHS3 Compliant or RoHS Compliant, meeting regulatory requirements for hazardous substance restrictions. ROHS3 represents the current standard; RoHS Compliant indicates earlier compliance designation.

Q: Can I substitute a through-hole part (135-3701-201) for the board edge part (908-22103)?

A: No, without PCB redesign. Through-hole mounting requires different PCB layout and hole patterns. Direct substitution is not possible. Board edge, surface mount parts (908-22100, 135-3711-801, 135-9711-801, 82_MMCX-S50-0-2/111_KE, MCSF96GT-T/R, R110422100) are suitable for direct substitution.

Q: What does MSL 1 (Unlimited) mean?

A: MSL (Moisture Sensitivity Level) 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part can be stored and handled without special humidity control measures, simplifying supply chain and manufacturing processes.
