Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full compliance with RoHS requirements and MSL Level 1 specifications. Selection among these alternatives should be based on the following criteria:

For Direct Mechanical Compatibility: The 3M 30334-5002HB, D2534-5002-AR, N2534-5002-RB, and N2534-5003RB, along with the Hirose HIF3FC-34PA-2.54DS(71), all satisfy the core mechanical and electrical interface requirements. Contact length variations in the post dimension (ranging from 0.110" to 0.165") accommodate different PCB thicknesses and assembly configurations.

For Extended Temperature Range Applications: Parts rated for -55°C to 105°C operating temperature (3M 30334-5002HB, D2534-5002-AR, N2534-5002-RB, and N2534-5003RB) provide broader thermal performance compared to the Hirose HIF3FC-34PA-2.54DS(71), which is rated to -55°C to 85°C.

For Higher Current Capacity: The 3M D2534-5002-AR, N2534-5002-RB, and N2534-5003RB are rated for 1.75A, compared to 1A for the 3M 30334-5002HB and Hirose HIF3FC-34PA-2.54DS(71).

For Voltage-Specified Applications: The Hirose HIF3FC-34PA-2.54DS(71) is the only part with an explicit voltage rating of 200V.

For Packaging Preferences: Bulk packaging is available from 3M (30334-5002HB, N2534-5002-RB, N2534-5003RB), tube packaging from 3M (D2534-5002-AR), and tray packaging from Hirose (HIF3FC-34PA-2.54DS(71)).

Frequently Asked Questions (FAQ)

Q: Can I substitute the TE Connectivity 3-1761680-1 with any of the listed alternatives?

A: Yes, all listed parts are electrically and mechanically compatible substitutes. They share identical position count (34), row configuration (2), pitch spacing (0.100"/2.54mm), mounting type (through-hole right-angle), shrouding (4-wall), termination method (solder), and fastening mechanism (push-pull). All maintain UL94 V-0 flammability rating and MSL Level 1 classification.

Q: What is the significance of contact length variations?

A: Contact length in the post dimension varies from 0.110" to 0.165" across the substitute parts. Longer post lengths (such as the 0.165" in the original 3-1761680-1 and 0.155" in the N2534-5003RB) accommodate thicker PCBs or provide additional solder joint length. Shorter post lengths (0.110" to 0.118") are suitable for standard PCB thicknesses. Selection depends on your specific PCB assembly requirements.

Q: Are there differences in contact material between the main part and substitutes?

A: Yes. The original 3-1761680-1 uses Phosphor Bronze contacts, while substitutes use either Brass or Copper Alloy. All materials provide equivalent electrical conductivity and reliability for this connector class. Contact finish specifications (gold mating surface with tin or gold post finish) remain consistent across all parts.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with RoHS directives. RoHS Compliant refers to the original 2002/95/EC directive, while ROHS3 Compliant refers to the updated 2011/65/EU directive. Both are acceptable for modern applications; ROHS3 represents the current standard.

Q: How do operating temperature ranges affect part selection?

A: The original 3-1761680-1 does not specify an operating temperature range. Substitute parts rated for -55°C to 105°C (3M 30334-5002HB, D2534-5002-AR, N2534-5002-RB, N2534-5003RB) provide broader thermal performance than the Hirose HIF3FC-34PA-2.54DS(71) rated to -55°C to 85°C. Select based on your application's thermal requirements.

Q: What packaging options are available?

A: Bulk packaging is available from 3M (30334-5002HB, N2534-5002-RB, N2534-5003RB), tube packaging from 3M (D2534-5002-AR), and tray packaging from Hirose (HIF3FC-34PA-2.54DS(71)). Packaging choice affects handling, storage, and automated assembly compatibility.

Q: Which substitute offers the highest current rating?

A: The 3M D2534-5002-AR, N2534-5002-RB, and N2534-5003RB all support 1.75A current rating, compared to 1A for the 3M 30334-5002HB and Hirose HIF3FC-34PA-2.54DS(71). Select the higher-rated parts for applications requiring greater current capacity.

Q: Is the Hirose HIF3FC-34PA-2.54DS(71) suitable for all applications?

A: The Hirose part is fully compatible mechanically and electrically. However, it has a lower operating temperature maximum (85°C versus 105°C for most 3M alternatives) and a lower current rating (1A versus 1.75A). Verify these specifications against your application requirements before selection.
