Key Parameters

Substitute Part Grouping Explanation

Substitution of the 202M122-19B is determined by the following critical parameters that must align between the main part and substitute candidates:

Thread Size Compatibility: The 1 5/16-18 UNEF thread specification is the primary mechanical interface with the connector body and must remain constant across substitutes.

Shell Size Compatibility: The insert size designation (22, 23) defines the connector series compatibility. Substitutes must support the same shell size range to ensure proper mating with existing connector hardware.

Cable Exit Angle: The 180° cable exit configuration is a fixed mechanical requirement for system integration and must be maintained in substitute parts.

Material and Plating Specifications: Aluminum construction with cadmium plating provides corrosion resistance and electromagnetic properties required for MIL-DTL-38999 compliance. These material specifications must be preserved.

Color Specification: Olive drab finish is a military standard requirement and must be maintained for specification compliance.

MIL-DTL-38999 Series Compatibility: The backshell must be certified for use with MIL-DTL-38999 Series I and II connectors.

The substitute part 99F1-22-1-B meets these critical parameters while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 99F1-22-1-B is the qualified substitute for the obsolete 202M122-19B based on the following engineering criteria:

Product Status: The 99F1-22-1-B maintains active product status with TE Connectivity, ensuring continued availability, technical support, and manufacturing consistency. The 202M122-19B is classified as obsolete and subject to discontinuation without notice.

Mechanical Compatibility: Both parts share identical thread size (1 5/16-18 UNEF) and cable exit angle (180°), ensuring direct mechanical compatibility with existing connector assemblies and cable management systems.

Material and Environmental Compliance: Both parts utilize aluminum construction with cadmium plating and maintain olive drab finish, preserving electromagnetic shielding characteristics and corrosion resistance properties required for MIL-DTL-38999 Series I and II applications.

Regulatory Alignment: Both parts carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications, maintaining export control and tariff compliance across supply chain transitions.

Shell Size Consideration: The 99F1-22-1-B is specified for shell size 22, which is compatible with the primary insert size of the 202M122-19B. Applications requiring shell size 23 compatibility should be evaluated against the cable opening range specification (1.114" ~ 1.654" / 28.30mm ~ 42.00mm) of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the 99F1-22-1-B directly replace the 202M122-19B in existing assemblies?

A: The 99F1-22-1-B is mechanically and electrically compatible with the 202M122-19B for MIL-DTL-38999 Series I and II connector applications. Both parts share identical thread size, cable exit angle, material composition, and plating specifications. The substitute part is specified for shell size 22 and supports cable openings from 1.114" to 1.654" (28.30mm to 42.00mm).

Q: What is the difference between the 202M122-19B and 99F1-22-1-B regarding shell size compatibility?

A: The 202M122-19B is rated for shell sizes 22 and 23. The 99F1-22-1-B is specified for shell size 22 with a cable opening range of 1.114" ~ 1.654" (28.30mm ~ 42.00mm). For applications requiring shell size 23 compatibility, the cable opening range of the substitute part should be verified against specific system requirements.

Q: Are there any compliance differences between these two parts?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications. Both are RoHS non-compliant and REACH Affected. The primary difference is product status: the 202M122-19B is obsolete, while the 99F1-22-1-B is active.

Q: What is the significance of the cable opening specification on the 99F1-22-1-B?

A: The cable opening range of 1.114" ~ 1.654" (28.30mm ~ 42.00mm) defines the acceptable cable diameter range for proper backshell engagement and strain relief. This specification ensures mechanical integrity and environmental sealing across the supported cable size range.

Q: Why is the 202M122-19B classified as obsolete?

A: Obsolete classification indicates that TE Connectivity has discontinued active manufacturing and support for this part number. The 99F1-22-1-B represents the active equivalent within the current product portfolio.

Q: Are both parts manufactured by the same company?

A: Both parts are manufactured by TE Connectivity Raychem Cable Protection, ensuring consistent quality standards, manufacturing processes, and technical support.

Q: What military standards do these backshells support?

A: Both the 202M122-19B and 99F1-22-1-B are designed for use with MIL-DTL-38999 Series I and II circular connectors. The 99F1-22-1-B references MIL-C-38999, which is the predecessor specification designation for the same connector series.
