Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The Molex 0702471452 and 0702471454 (C-Grid 70247 series) provide direct functional equivalence to the TE Connectivity 2-1761680-5. Both parts maintain identical pitch, position count, row configuration, and mounting orientation. The primary distinction is packaging format: 0702471452 is supplied in bulk, while 0702471454 is supplied in tray format. Both are active products with ROHS3 compliance and unlimited moisture sensitivity rating. These parts are recommended as primary substitutes for new procurement.

Secondary Substitutes (Active Status with Design Variations):

The HARTING 09185145323 and 09185146323 (SEK series) offer functional compatibility with extended operating temperature range (-55°C to 125°C) compared to the original part. These components feature latch holder fastening instead of push-pull, representing a design variation that maintains mechanical interface compatibility. Both are active products with ROHS3 compliance. The 09185146323 is supplied in tray format, while 09185145323 is supplied in bulk.

The Amphenol ICC 10056845-114LF (Quickie™ series) provides an active alternative with detent lock fastening and thermoplastic insulation material. This part maintains all critical dimensional and electrical parameters while offering enhanced current rating capability (3.4A per contact specification available in related series documentation). Supplied in tube format with RoHS compliance.

The 3M 30314-5002HB (303 series) is an active substitute with operating temperature range of -55°C to 105°C and specified current rating of 1A. This part features gold contact finish on both mating and post surfaces, distinguishing it from the original tin-plated post design. Supplied in bulk format with RoHS compliance.

Samtec Flex Stack HTST Series (Premium Alternatives):

The Samtec HTST-107-04-G-D-RA, HTST-107-04-S-D-RA, and HTST-107-05-G-D-RA represent premium alternatives with extended operating temperature range (-55°C to 125°C) and higher current rating (3.4A per contact). These parts utilize Liquid Crystal Polymer (LCP) insulation material and phosphor bronze contacts. The HTST-107-04-G-D-RA and HTST-107-05-G-D-RA feature gold post finish, while HTST-107-04-S-D-RA features tin post finish. The primary distinction between HTST-107-04 and HTST-107-05 variants is contact length post dimension (0.130" versus 0.230"). All are active products with ROHS3 compliance.

Non-Substitute Component:

The HARTING 09185146813 is a receptacle connector with female socket contacts and IDC termination for ribbon cable (26-28 AWG). This component is not a substitute for the original header connector and serves a complementary mating function in connector systems.

Compliance and Procurement Considerations:

All recommended substitute parts maintain UL94 V-0 flammability rating and MSL 1 (unlimited) moisture sensitivity classification. All active substitutes carry either RoHS or ROHS3 compliance status. Selection between substitutes should be based on specific application requirements regarding operating temperature range, current capacity, fastening mechanism preference, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702471452 directly replace the TE Connectivity 2-1761680-5 in existing designs?

A: Yes. The Molex 0702471452 maintains identical pitch (0.100"), position count (14), row configuration (2 rows), mounting type (through hole, right angle), and shrouding (4 wall). All critical electrical and mechanical parameters are equivalent. The primary difference is packaging format (bulk versus original tray). No design modification is required.

Q: What is the difference between the Molex 0702471452 and 0702471454?

A: Both parts are electrically and mechanically identical. The distinction is packaging format: 0702471452 is supplied in bulk packaging, while 0702471454 is supplied in tray packaging. Selection depends on procurement and inventory management requirements.

Q: Why do some substitute parts have different operating temperature ranges?

A: Operating temperature range is a design specification that does not affect connector pitch, position count, or mating interface geometry. The original TE Connectivity 2-1761680-5 does not specify an operating temperature range. Substitute parts with specified temperature ranges (such as HARTING SEK series at -55°C to 125°C) provide additional environmental capability without compromising compatibility with the original design interface.

Q: What is the significance of contact finish differences between substitutes?

A: Contact finish (gold or tin) affects electrical conductivity and corrosion resistance characteristics. The original part specifies gold mating finish with tin post finish. Substitutes with alternative post finishes (such as 3M 30314-5002HB with gold post finish) maintain electrical compatibility while offering different corrosion resistance profiles. Selection should be based on application environment and electrical performance requirements.

Q: Are the Samtec HTST series parts compatible with the original design?

A: Yes. The Samtec HTST-107 series maintains all critical mating parameters: 14 positions, 2 rows, 0.100" pitch, right-angle through-hole mounting, and 4-wall shrouding. The primary distinctions are insulation material (Liquid Crystal Polymer versus Polybutylene Terephthalate), contact material (phosphor bronze), and enhanced current rating capability (3.4A per contact). These design variations do not preclude functional substitution.

Q: What is the difference between HTST-107-04-G-D-RA and HTST-107-05-G-D-RA?

A: Both parts are identical except for contact length post dimension. The HTST-107-04-G-D-RA has 0.130" post length, while HTST-107-05-G-D-RA has 0.230" post length. Selection depends on specific board thickness and solder joint requirements in the application.

Q: Can the HARTING 09185146813 be used as a substitute?

A: No. The HARTING 09185146813 is a receptacle connector with female socket contacts and IDC termination for ribbon cable. It is not a substitute for the header connector. This part serves as a complementary mating component in connector systems.

Q: What does "push-pull" versus "latch holder" fastening mean?

A: Both fastening types provide mechanical retention between mated connectors. Push-pull fastening (original part and most substitutes) uses a simple push-to-connect, pull-to-disconnect mechanism. Latch holder fastening (HARTING SEK series) uses a latching mechanism for enhanced retention. Both mechanisms maintain electrical continuity and are mechanically compatible with standard 0.100" pitch connector systems.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitute parts carry either RoHS or ROHS3 compliance certification. The original TE Connectivity 2-1761680-5 is RoHS compliant. All active substitutes maintain this compliance status, ensuring compatibility with RoHS-regulated applications and procurement requirements.

Q: What packaging formats are available for these substitutes?

A: Substitute parts are available in multiple packaging formats: bulk (loose components), tray (organized array), and tube (rolled packaging). Specific format availability varies by manufacturer and part number. Procurement selection should be based on assembly process requirements and inventory management practices.

Q: Do all substitutes have the same current rating?

A: No. The original part does not specify a current rating. Substitute parts with specified current ratings include 3M 30314-5002HB (1A) and Samtec HTST series (3.4A per contact). Parts without specified current ratings are suitable for general-purpose applications. Selection of parts with higher current ratings provides additional capability for power distribution applications.
