Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the TE Connectivity 103311-6?

A: The critical parameters are: 26-position, 2-row header configuration; 0.100" (2.54mm) mating pitch and row spacing; through-hole, right-angle mounting; shrouded 4-wall design; solder termination; and UL94 V-0 flammability rating. All identified substitutes meet these specifications.

Q: Can I use a substitute part with a different contact shape?

A: The Amphenol ICC 69155-026LF features circular contacts instead of square contacts. This part is functionally equivalent for mating and electrical performance within the specified parameters. Contact shape does not affect interchangeability for standard board-to-cable or board-to-board applications.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The TE Connectivity 103311-6 is supplied in Bulk packaging. Substitute parts are available in Bulk (HARTING 09185267323, 3M 30326-5002HB, Amphenol ICC 69155-026LF, 3M N2526-5002-RB), Tray (Molex 0702472652, HARTING 09185266323), or Tube (3M D2526-5002-AR) packaging. Packaging format does not affect functional performance and is determined by procurement and inventory requirements.

Q: What is the difference between push-pull and latch holder fastening types?

A: Both fastening types provide secure mating and are functionally equivalent for connector retention. Push-pull fastening uses a spring-loaded mechanism for quick connect/disconnect. Latch holder fastening uses a mechanical latch for positive retention. The HARTING parts (09185266323 and 09185267323) use latch holder fastening, while other substitutes use push-pull fastening. Selection depends on application requirements for mating force and disconnect security.

Q: Which substitute parts are compliant with RoHS and REACH regulations?

A: For RoHS compliance, all substitutes except the primary TE Connectivity 103311-6 are compliant (ROHS3 or RoHS Compliant status). For REACH compliance, all substitutes except Amphenol ICC 69155-026LF are REACH Unaffected. The Molex 0702472652, HARTING parts, 3M 30326-5002HB, 3M D2526-5002-AR, and 3M N2526-5002-RB meet both RoHS and REACH requirements.

Q: What is the difference in contact post length between the main part and substitutes?

A: The TE Connectivity 103311-6 has a contact post length of 0.135" (3.43mm). Substitute parts range from 0.105" (2.67mm) to 0.120" (3.05mm). These variations are within acceptable tolerances for standard PCB through-hole mounting and do not affect functional interchangeability. Post length differences are accommodated by standard solder joint formation during assembly.

Q: Can I use a substitute part with a higher current rating?

A: Yes. The 3M D2526-5002-AR and N2526-5002-RB provide a current rating of 1.75A per contact, compared to the 1A specification of the TE Connectivity 103311-6. Using a higher-rated part provides additional safety margin and is suitable for applications requiring increased current capacity.

Q: Are there temperature range differences I should consider?

A: The TE Connectivity 103311-6 operates from -65°C to 105°C. The HARTING 09185266323 and 09185267323 extend the upper limit to 125°C. The 3M parts (30326-5002HB, D2526-5002-AR, N2526-5002-RB) maintain the 105°C upper limit but specify a -55°C minimum. For applications requiring the full -65°C lower limit, the TE Connectivity 103311-6 or HARTING parts are appropriate selections.

Q: What contact material differences exist between the main part and substitutes?

A: The TE Connectivity 103311-6 uses brass contacts. Substitutes use brass (3M 30326-5002HB, 3M D2526-5002-AR), phosphor bronze (Molex 0702472652, Amphenol ICC 69155-026LF), or copper alloy (HARTING 09185266323, HARTING 09185267323, 3M N2526-5002-RB). All materials provide equivalent electrical conductivity and contact reliability for the specified current and voltage applications.

Q: How do insulation material differences affect part selection?

A: The TE Connectivity 103311-6 does not specify insulation material. Substitutes use polybutylene terephthalate (PBT) with glass fill, polyester with glass fill, or polycyclohexylenedimethylene terephthalate (PCT) with polyester and glass fill. All materials meet UL94 V-0 flammability requirements and provide equivalent mechanical and electrical insulation properties for standard applications.

Q: What inventory levels are available for each substitute part?

A: Inventory availability is as follows: TE Connectivity 103311-6 (685 units), Molex 0702472652 (1211 units), HARTING 09185266323 (1005 units), HARTING 09185267323 (961 units), 3M 30326-5002HB (5552 units), Amphenol ICC 69155-026LF (1027 units), 3M D2526-5002-AR (2030 units), 3M N2526-5002-RB (6780 units). The 3M N2526-5002-RB offers the highest inventory availability.
