TE Connectivity 1-1761682-1 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-1761682-1 is an active-status rectangular connector header designed for through-hole, right-angle mounting applications. This 34-position, 2-row connector with 0.100" (2.54mm) pitch serves board-to-cable/wire interconnection requirements in industrial and commercial electronics. The connector features shrouded 4-wall construction with push-pull fastening, gold-plated mating contacts, and tin-plated posts rated for 1A per contact at 250VAC operation across -65°C to 105°C temperature range.

Equivalent and substitute parts are necessary when original inventory is unavailable, when alternative packaging formats are required, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS3 or RoHS regulations, ensuring regulatory compliance for new designs and production environments.

Primary Substitutes (Highest Compatibility):

The 3M 30334-5002HB, 3M D2534-5002-AR, and 3M N2534-5003RB connectors provide direct functional equivalence to the TE Connectivity 1-1761682-1. These parts share identical 34-position, 2-row configuration with 0.100" pitch, through-hole right-angle mounting, and 4-wall shrouding. All maintain UL94 V-0 flammability rating and unlimited moisture sensitivity classification. The 3M 30334-5002HB offers the largest current inventory (3056 units) and matches the original push-pull fastening mechanism. The 3M D2534-5002-AR and N2534-5003RB provide enhanced current ratings (1.75A) and are available in alternative packaging formats (tube and bulk, respectively).

Secondary Substitutes (Acceptable with Design Verification):

The Hirose Electric HIF3FC-34PA-2.54DS(71) connector meets all critical dimensional and electrical parameters with identical 34-position, 2-row 0.100" pitch configuration. This part operates across -55°C to 85°C, which encompasses the standard industrial temperature range but does not extend to the -65°C lower limit of the original part. Selection of this substitute requires confirmation that the application does not require operation below -55°C. The Hirose connector is packaged in trays and maintains ROHS3 compliance.

Alternative Fastening Mechanism:

The HARTING 09185347323 connector provides equivalent 34-position, 2-row 0.100" pitch configuration with latch holder fastening instead of push-pull. This fastening mechanism difference does not affect electrical performance but requires mating connector compatibility verification. The HARTING part operates across -55°C to 125°C, exceeding the original temperature range, and is ROHS3 compliant. Current rating is not specified for this part; confirmation of 1A minimum per-contact rating is required before selection.

Packaging Considerations:

The original TE Connectivity 1-1761682-1 is supplied in bulk packaging. Substitute parts are available in bulk (HARTING 09185347323, 3M 30334-5002HB, 3M N2534-5003RB), tube (3M D2534-5002-AR), and tray (Hirose HIF3FC-34PA-2.54DS(71)) formats. Packaging selection depends on production workflow, storage requirements, and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09185347323 substitute for the TE Connectivity 1-1761682-1 if the application uses push-pull mating connectors?

A: No. The HARTING 09185347323 features latch holder fastening, while the original part uses push-pull fastening. The mating connector must be compatible with the latch holder mechanism. Verify mating connector specifications before substitution.

Q: What is the temperature limitation when using the Hirose HIF3FC-34PA-2.54DS(71) as a substitute?

A: The Hirose connector operates from -55°C to 85°C. The original TE Connectivity part operates from -65°C to 105°C. The Hirose substitute does not support operation below -55°C or above 85°C. Confirm that the application does not require these extended temperature ranges before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are either ROHS3 Compliant or RoHS Compliant, meeting regulatory requirements for electronics manufacturing and distribution.

Q: Do the 3M D2534-5002-AR and N2534-5003RB connectors with 1.75A current ratings provide additional design margin?

A: The 1.75A current rating exceeds the original 1A per-contact specification. These parts provide additional current capacity for applications requiring higher per-contact current handling. However, the mating connector and circuit design must also support the higher current rating to realize this benefit.

Q: What is the significance of contact finish differences between tin and gold plating on the post?

A: Both tin and gold post finishes are acceptable for solder termination. Tin plating is standard for wave soldering and reflow processes. Gold plating provides enhanced corrosion resistance in high-humidity or corrosive environments. Selection depends on application environment and soldering process specifications.

Q: Can the 3M 30334-5002HB be used as a direct replacement without PCB redesign?

A: The 3M 30334-5002HB maintains identical 34-position, 2-row 0.100" pitch configuration, through-hole right-angle mounting, and push-pull fastening. Contact lengths and insulation heights vary within acceptable ranges (0.236" mating contact length versus 0.240" original; 0.331" insulation height versus 0.350" original). PCB footprint compatibility requires verification of hole spacing and mounting pad dimensions, but no redesign is typically necessary for standard through-hole layouts.

Q: Which substitute part offers the best inventory availability?

A: The 3M 30334-5002HB offers the highest inventory level at 3056 units in stock, followed by the 3M D2534-5002-AR with 1749 units and the 3M N2534-5003RB with 1422 units. The original TE Connectivity 1-1761682-1 has 1007 units available.

Q: Are there voltage rating differences between the original and substitute parts?

A: The original TE Connectivity 1-1761682-1 is rated for 250VAC. The Hirose HIF3FC-34PA-2.54DS(71) is rated for 200V. The HARTING 09185347323 and 3M parts (30334-5002HB, D2534-5002-AR, N2534-5003RB) do not specify voltage ratings. For applications requiring 250VAC operation, the original TE Connectivity part or the Hirose part (if 200V is acceptable) are appropriate selections. Verify mating connector voltage ratings for complete circuit compliance.

Q: What insulation material differences exist between substitute parts?

A: The original uses polycyclohexylenedimethylene terephthalate (PCT). Substitutes use polybutylene terephthalate (PBT), PCT, or combinations with polyester and glass fill. All materials maintain UL94 V-0 flammability rating. Material selection affects mechanical strength, temperature performance, and moisture absorption characteristics. All listed materials are suitable for standard industrial connector applications.
