Parameter Comparison

Engineering Selection Recommendations

Primary Part: 910A205F (Winchester Interconnect)

Use the 910A205F when Winchester Interconnect is the specified manufacturer or when procurement contracts require this specific source. The part is actively produced and maintains RoHS compliance. Packaging is provided as individual units with included contact and ferrule components.

Substitute Part: 142-0407-011 (Cinch Connectivity Solutions Johnson)

The 142-0407-011 qualifies as a direct substitute based on matching electrical specifications, mechanical interface, and environmental ratings. This part is actively produced and maintains ROHS3 compliance, which exceeds RoHS requirements. The substitute offers expanded cable group compatibility (RG-58, 141, 303 versus RG-58 only) and includes a sleeve component in addition to contact and ferrule. Bulk packaging is available for this substitute.

Compliance Considerations:

Both parts carry EAR99 export classification and match HTSUS commodity codes. The 142-0407-011 includes REACH Affected status, which may require additional documentation in certain regulatory jurisdictions. Both parts maintain MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special storage or handling requirements.

Frequency Specification:

The 910A205F operates to 12.5 GHz while the 142-0407-011 operates to 12.4 GHz. For applications requiring operation above 12.4 GHz, the 910A205F is the required selection. For applications operating at or below 12.4 GHz, both parts are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 142-0407-011 be used as a direct replacement for the 910A205F in existing designs?

A: Yes, for applications operating at frequencies up to 12.4 GHz. Both connectors share identical SMA male pin configuration, 50-ohm impedance, crimp shield termination, threaded fastening, and operating temperature range. The mechanical interface and electrical performance are equivalent within the specified frequency range.

Q: What is the difference in contact termination between these parts?

A: The 910A205F specifies crimp termination only. The 142-0407-011 offers both crimp and solder termination options. When using the 142-0407-011 as a substitute, crimp termination should be selected to maintain process consistency with the original design.

Q: Are there cable compatibility differences between these parts?

A: The 910A205F is specified for RG-58 cable group. The 142-0407-011 supports RG-58, 141, and 303 cable groups. Both parts are compatible with RG-58 cable. If the design uses RG-141 or RG-303 cable, the 142-0407-011 provides expanded compatibility.

Q: What packaging differences exist between these parts?

A: The 910A205F is supplied as individual units. The 142-0407-011 is available in bulk packaging. Both include connector body, contact, and ferrule/sleeve components. Verify packaging requirements for your procurement process.

Q: Do these parts have different compliance certifications?

A: The 910A205F is RoHS Compliant. The 142-0407-011 is ROHS3 Compliant, which represents a more recent and stringent standard. Both meet RoHS requirements. The 142-0407-011 carries REACH Affected status, requiring additional documentation in certain jurisdictions.

Q: What is the maximum frequency limitation for substitution?

A: The 910A205F operates to 12.5 GHz. The 142-0407-011 operates to 12.4 GHz. For applications requiring operation above 12.4 GHz, the 910A205F must be used. For applications at or below 12.4 GHz, substitution is valid.

Q: Are mating cycle ratings identical?

A: Yes, both parts specify 500 mating cycles. Mechanical durability and connector life expectancy are equivalent.

Q: Can these parts be intermixed in the same assembly?

A: Yes, both parts are mechanically and electrically compatible. However, design documentation should specify which part is approved for use to maintain traceability and ensure consistent procurement.
