Engineering Selection Recommendations

All nine substitute parts maintain active product status and meet the mandatory electrical and mechanical compatibility requirements for the HARTING 09185145321. Selection among qualified alternatives should be based on the following compliance and certification factors:

ROHS3 Compliant Options (Preferred for Restricted Substance Compliance):

Molex 0702471454
TE Connectivity 1761682-5
TE Connectivity 2-1761605-5
TE Connectivity 5103310-2
TE Connectivity 5103311-2
Samtec HTST-107-04-G-D-RA

RoHS Compliant (Non-ROHS3) Options:

Amphenol ICC 10056845-114LF
3M 30314-5002HB

RoHS Non-Compliant Options (Legacy Applications Only):

TE Connectivity 103310-2
TE Connectivity 103311-2

For applications requiring REACH compliance, the following parts are unaffected or have defined vendor status: HARTING 09185145321, Molex 0702471454, 3M 30314-5002HB, TE Connectivity 1761682-5, TE Connectivity 5103310-2, TE Connectivity 5103311-2, and Samtec HTST-107-04-G-D-RA.

The Samtec HTST-107-04-G-D-RA offers the highest current rating per contact (3.4A) and matches the original operating temperature range of -55°C to 125°C, making it suitable for high-current or extended temperature applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly into a design using the HARTING 09185145321?

A: Yes, all nine listed parts are qualified substitutes. They maintain identical mating pitch (0.100"), row spacing (0.100"), position count (14 in 2 rows), mounting orientation (through-hole right-angle), shrouding configuration (4-wall), and contact finish specifications (gold mating, tin post). Mechanical and electrical compatibility is assured within the specified parameter ranges.

Q: What is the difference between the fastening types (Latch Holder, Push-Pull, Detent Lock)?

A: Fastening type determines the mating mechanism between header and connector. Latch Holder (original part) uses latching clips. Push-Pull designs use friction-based retention. Detent Lock uses positive detent engagement. All three mechanisms are functionally equivalent for board-to-cable connections and do not affect electrical performance.

Q: Are there temperature range differences I should consider?

A: The HARTING 09185145321 operates from -55°C to 125°C. Most substitutes operate from -65°C to 105°C, providing lower minimum temperature but reduced maximum temperature. The Samtec HTST-107-04-G-D-RA matches the original -55°C to 125°C range. For applications exceeding 105°C, select either the original part or the Samtec alternative.

Q: What packaging options are available?

A: Bulk packaging is available from HARTING, TE Connectivity (103310-2, 1761682-5, 2-1761605-5), and 3M. Tube packaging is available from Amphenol ICC, TE Connectivity (103311-2, 5103310-2, 5103311-2), and Samtec. Tray packaging is available from Molex. Packaging does not affect component performance and is selected based on assembly process requirements.

Q: Which substitute offers the best compliance profile?

A: For maximum compliance coverage, the Samtec HTST-107-04-G-D-RA, TE Connectivity 1761682-5, and TE Connectivity 2-1761605-5 are ROHS3 compliant with REACH unaffected status. These parts are suitable for the most restrictive regulatory environments.

Q: Does contact material (Copper Alloy, Brass, Phosphor Bronze) affect performance?

A: Contact material variations (Copper Alloy, Brass, Phosphor Bronze) are within allowable substitution parameters and do not affect electrical performance for standard signal applications. All materials provide equivalent conductivity and reliability within the specified operating conditions.

Q: Can I mix and match headers and mating connectors from different manufacturers?

A: All substitute headers maintain the 0.100" (2.54mm) pitch and 2-row configuration, ensuring mechanical compatibility with standard 0.100" pitch connectors. Verify mating connector specifications independently to confirm compatibility with your specific application.
