Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2-1761606-9 is the direct functional equivalent for the obsolete 1761688-9. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status with TE Connectivity, ensuring continued availability and manufacturing support. The obsolete status of the original part necessitates transition to an active equivalent for new designs and ongoing production requirements.

Regulatory Compliance: Both parts maintain UL94 V-0 flammability certification and are constructed from identical insulation materials (Polybutylene Terephthalate). The substitute part carries ROHS3 compliance, representing an advancement in regulatory adherence compared to the original RoHS Compliant designation. Both parts are classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes.

Mechanical and Electrical Equivalence: The substitute part maintains identical specifications across all critical connector parameters: 26-position, 2-row configuration at 0.100" (2.54mm) pitch, through-hole solder termination, shrouded 4-wall design, and latch lock/eject fastening. Contact materials, finishes, and electrical ratings (1A per contact, 250VAC) are identical. Operating temperature range (-65°C ~ 105°C) and moisture sensitivity level (MSL 1) are preserved.

Minor Dimensional Variations: Contact length specifications show minor variations (mating contact 0.240" versus 0.237", post contact 0.165" versus 0.102", insulation height 0.350" versus 0.404"). These variations are functionally equivalent within the AMP-Latch series design parameters and do not affect electrical performance or mechanical compatibility in standard board-to-cable/wire applications.

Availability Advantage: The substitute part 2-1761606-9 offers significantly higher inventory availability (4057 pieces in stock versus 718 pieces for the obsolete part), supporting both immediate procurement needs and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 2-1761606-9 be used as a direct replacement for the 1761688-9 in existing designs?

A: Yes. The 2-1761606-9 maintains identical connector type, position count, pitch spacing, mounting method, and electrical ratings. The part is mechanically and electrically compatible for board-to-cable/wire applications requiring 26-position, 2-row headers at 0.100" (2.54mm) spacing with 1A per contact and 250VAC ratings.

Q: What are the differences in contact length specifications between the two parts?

A: The mating contact length differs by 0.003" (0.08mm), and the post contact length differs by 0.063" (1.59mm). The insulation height of the substitute is 0.054" (1.37mm) greater. These dimensional variations are functionally equivalent within the AMP-Latch series design envelope and do not affect standard through-hole solder joint formation or electrical performance.

Q: Are there any compliance differences between the original and substitute parts?

A: Both parts maintain UL94 V-0 flammability certification and identical insulation material composition. The substitute part carries ROHS3 compliance, representing current regulatory standards compared to the original RoHS Compliant designation. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the significance of the contact finish difference (Gold versus Gold or Gold-Palladium)?

A: The substitute part specifies Gold or Gold-Palladium mating contact finish, while the original specifies Gold only. Both finishes provide equivalent electrical performance and corrosion resistance at the specified 30.0µin (0.76µm) thickness. The palladium option in the substitute represents a manufacturing flexibility that does not affect connector performance in standard applications.

Q: How does packaging differ between these parts?

A: The original part 1761688-9 packaging is not specified in the documentation. The substitute part 2-1761606-9 is supplied in Tube packaging, which is standard for through-hole connector headers and facilitates automated assembly processes.

Q: Is the substitute part suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -65°C to 105°C, maintaining electrical and mechanical performance throughout this specification.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
