Substitute Part Grouping Explanation

Substitution of the obsolete 166997-2 with the active equivalent 166995-2 is based on strict electrical and mechanical parameter alignment. Both components share identical specifications across all critical functional parameters: D-Sub contact classification, AMPLIMITE HDP-20 series designation, male pin contact type, stamped form factor, 28-32 AWG wire gauge compatibility, crimp termination method, brass material composition, gold contact finish, contact size 20, and insulation support features.

The primary differentiators between these parts are packaging format and product status. The 166997-2 is supplied in bulk packaging and carries obsolete status, while the 166995-2 is supplied in cut tape (CT) packaging and maintains active product status. Both components maintain equivalent RoHS compliance and MSL ratings.

Key Parameters Determining Substitution:

• Contact Type: Male Pin
• Wire Gauge: 28-32 AWG
• Contact Termination: Crimp
• Contact Material: Brass
• Contact Finish: Gold
• Contact Size: 20
• Series: AMPLIMITE HDP-20
• Features: Insulation Support

Engineering Selection Recommendations

The 166995-2 serves as the direct functional equivalent to the obsolete 166997-2. Selection of the 166995-2 is supported by the following engineering criteria:

Product Status: The 166995-2 maintains active product status, ensuring continued availability and manufacturer support, whereas the 166997-2 is obsolete and subject to supply discontinuation.

Compliance Certification: Both components maintain RoHS compliance. The 166995-2 carries ROHS3 certification, representing current regulatory compliance standards. Both components are classified under identical ECCN and HTSUS codes, confirming equivalent regulatory treatment.

Electrical and Mechanical Compatibility: All functional parameters are identical between the two components, including contact geometry, termination method, wire gauge rating, and material composition. The contact finish thickness variance (31.5µin versus 30.0µin) remains within acceptable tolerance ranges for D-Sub contact applications and does not affect functional performance.

Packaging Consideration: The transition from bulk to cut tape (CT) packaging reflects standard industry practice for active components. Cut tape packaging is suitable for both manual and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 166995-2 be used as a direct replacement for the 166997-2 in existing designs?

A: Yes. The 166995-2 is electrically and mechanically equivalent to the 166997-2 across all functional parameters. Both components are rated for identical wire gauges (28-32 AWG), employ identical crimp termination methods, and are compatible with AMPLIMITE HDP-20 series connector housings.

Q: What is the significance of the contact finish thickness difference between these parts?

A: The contact finish thickness variance (31.5µin for 166997-2 versus 30.0µin for 166995-2) represents a minor difference within acceptable tolerance ranges for D-Sub contact applications. Both thicknesses provide equivalent corrosion resistance and electrical performance for signal-level applications.

Q: Why has the packaging changed from bulk to cut tape?

A: Cut tape (CT) packaging is the current standard for active D-Sub contact components. This packaging format accommodates both manual assembly and automated pick-and-place equipment, providing greater flexibility for production environments.

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

A: Both components maintain RoHS compliance. The 166995-2 carries ROHS3 certification, representing the current regulatory standard. Both components share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What is the inventory status of the substitute part?

A: The 166995-2 maintains substantial inventory availability (86,653 pieces in stock), ensuring reliable supply for production requirements. The obsolete 166997-2 has limited remaining inventory (1,108 pieces).

Q: Are both parts suitable for the same wire gauge applications?

A: Yes. Both the 166997-2 and 166995-2 are rated for 28-32 AWG wire gauges and employ identical crimp termination specifications, ensuring compatibility across the full wire gauge range.
