Engineering Selection Recommendations

All identified substitute parts maintain Active product status and comply with RoHS or ROHS3 regulations, ensuring regulatory compliance for current and future applications. The following selection criteria apply:

For Direct Mechanical and Electrical Equivalence: The HARTING 09185347323 and 09185346323 connectors provide equivalent functionality with ROHS3 compliance and extended operating temperature range (-55°C to 125°C). These parts are suitable for applications requiring enhanced thermal performance.

For 3M Series Compatibility: The 3M N2534-5002-RB and N2534-5003RB connectors offer RoHS compliance with higher current ratings (1.75A) and extended operating temperature range (-55°C to 105°C). The primary difference between these two 3M parts is contact length post specification: N2534-5002-RB features 0.112" (2.84mm) post length, while N2534-5003RB features 0.155" (3.94mm) post length for applications requiring deeper board penetration.

For Enhanced Current Capacity: The Samtec TST-117-04-G-D-LA connector delivers the highest current rating at 3.4A per contact with ROHS3 compliance and extended operating temperature range (-55°C to 125°C). This part incorporates kinked pin termination and phosphor bronze contact material, suitable for high-current applications.

For Standard 3M 303 Series: The 3M 30334-5002HB provides Push-Pull fastening with 1A current rating and UL94 V-0 flammability rating, operating across -55°C to 105°C temperature range.

For Hirose HIF3FC Series: The Hirose HIF3FC-34PA-2.54DS(71) connector features 200V voltage rating specification and 1A current rating with ROHS3 compliance, suitable for applications requiring voltage specification documentation.

For 3M D2500 Series: The 3M D2534-5002-AR connector provides ROHS3 compliance with 1.75A current rating and extended operating temperature range (-55°C to 105°C), packaged in tube format.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine substitution compatibility for the TE Connectivity 3-827746-4?

A: The following parameters must match exactly for substitution: 34-position count, 2-row configuration, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, through-hole right-angle mounting, shrouded 4-wall construction, solder termination, and gold-plated mating contacts. All identified substitute parts meet these specifications.

Q: Can I substitute the TE Connectivity 3-827746-4 with a connector having different insulation color?

A: Yes. Insulation color is a cosmetic parameter that does not affect electrical or mechanical function. The HARTING 09185346323 and 09185347323 connectors feature gray insulation instead of black, but are otherwise functionally equivalent.

Q: What is the difference between the 3M N2534-5002-RB and N2534-5003RB connectors?

A: Both connectors share identical specifications except for contact length post dimension. The N2534-5002-RB features 0.112" (2.84mm) post length, while the N2534-5003RB features 0.155" (3.94mm) post length. Selection depends on required board penetration depth for solder joint formation.

Q: Which substitute part offers the highest current rating?

A: The Samtec TST-117-04-G-D-LA connector provides the highest current rating at 3.4A per contact, compared to 1.75A for 3M N2534 series and 1A for Hirose and 3M 303 series connectors.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts comply with either RoHS or ROHS3 regulations. The TE Connectivity 3-827746-4 is RoHS Compliant, while HARTING, Samtec, and 3M D2534 parts are ROHS3 Compliant. Both compliance levels are acceptable for regulatory purposes.

Q: What operating temperature ranges are available among substitute parts?

A: Operating temperature ranges vary: HARTING and Samtec parts operate from -55°C to 125°C, while 3M 303 and D2500 series operate from -55°C to 105°C. The Hirose HIF3FC series operates from -55°C to 85°C. Selection depends on application thermal requirements.

Q: Does packaging format affect connector functionality?

A: No. Packaging format (Bulk, Tube, or Tray) is a supply chain consideration that does not affect electrical or mechanical performance. All substitute parts are functionally equivalent regardless of packaging format.

Q: Can I use the Hirose HIF3FC-34PA-2.54DS(71) as a direct replacement?

A: Yes. The Hirose connector meets all critical mechanical and electrical specifications. However, it features the lowest operating temperature maximum at 85°C and includes a 200V voltage rating specification not present in other substitutes. Verify application temperature requirements before selection.

Q: What is the significance of contact material differences among substitute parts?

A: Contact material variations (Copper Alloy, Brass, Phosphor Bronze) affect mechanical durability and current-carrying capacity but do not prevent substitution. All materials are suitable for standard interconnect applications. Phosphor Bronze in the Samtec connector provides enhanced durability for high-cycle mating applications.

Q: Are there inventory considerations for substitute part selection?

A: Yes. Current inventory levels vary: 3M 30334-5002HB (3056 pcs), HARTING 09185346323 (3840 pcs), 3M N2534-5002-RB (1250 pcs), 3M N2534-5003RB (1422 pcs), 3M D2534-5002-AR (1749 pcs), HARTING 09185347323 (811 pcs), Hirose HIF3FC-34PA-2.54DS(71) (997 pcs), and Samtec TST-117-04-G-D-LA (757 pcs). Inventory availability may influence procurement decisions for high-volume applications.
