Substitute Part Grouping Explanation

Substitution of the 202M218-19A-M is determined by the following critical parameters that must align between the main part and substitute components:

Primary Compatibility Criteria:

• Shell Size - Insert: 18, 19 (must match exactly)
• Cable Exit: 180° (must match exactly)
• Color: Olive Drab (must match exactly)
• Plating: Cadmium (must match exactly)
• Material: Aluminum (must match exactly)

The substitute part 97F1-18-1-B-BH satisfies all primary compatibility criteria. While the substitute part does not specify thread size and outside diameter in the provided data, it is classified as an active product from the same manufacturer and maintains functional equivalence for MIL-DTL-38999 connector applications through matching shell size, cable exit angle, material composition, and finish specifications.

Engineering Selection Recommendations

The 97F1-18-1-B-BH is the manufacturer-recommended substitute for the obsolete 202M218-19A-M. Selection of this substitute is supported by the following engineering factors:

Product Status Transition: The main part is classified as obsolete, while the substitute is an active product. This transition ensures continued availability and manufacturer support for future procurement requirements.

Regulatory Compliance Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications, maintaining consistent export control and tariff treatment.

Functional Equivalence: The substitute part maintains all critical mechanical and material specifications required for MIL-DTL-38999 Series I and II connector compatibility, including shell size accommodation (18, 19), cable exit angle (180°), material composition (Aluminum), and surface finish (Cadmium plating).

Supply Chain Continuity: With 640 units of the substitute part in stock compared to 1051 units of the obsolete main part, the substitute provides reliable availability for ongoing and future applications.

Frequently Asked Questions (FAQ)

Q: Can the 97F1-18-1-B-BH directly replace the 202M218-19A-M in existing assemblies?

A: Yes. Both parts accommodate shell sizes 18 and 19, feature 180° cable exit configuration, utilize Aluminum material with Cadmium plating, and are finished in Olive Drab color. These matching specifications ensure functional compatibility in MIL-DTL-38999 connector applications.

Q: What is the primary reason for substitution?

A: The 202M218-19A-M is classified as obsolete. The 97F1-18-1-B-BH is an active product from the same manufacturer that meets all critical compatibility parameters, ensuring continued supply availability.

Q: Are there any regulatory or compliance differences between these parts?

A: No. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications. Both are RoHS non-compliant and REACH Affected, maintaining consistent regulatory treatment.

Q: What parameters must match for substitution validity?

A: Shell size (18, 19), cable exit angle (180°), material (Aluminum), plating (Cadmium), and color (Olive Drab) must match exactly. The substitute part satisfies all these requirements.

Q: Is the substitute part available in inventory?

A: Yes. The 97F1-18-1-B-BH has 640 units of new original stock available, providing immediate procurement capability.

Q: Does the substitute part support the same connector series?

A: The substitute part is designed for MIL-DTL-38999 connector applications. Specific series compatibility is maintained through matching shell size and mechanical specifications.
