Engineering Selection Recommendations

Direct Equivalent - Amphenol ICC 75867-307LF

The 75867-307LF is the direct successor to the obsolete 75867-307. Both parts share identical mechanical and electrical specifications with the exception of RoHS compliance status. The 75867-307LF is active in production and carries RoHS Compliant certification, making it the preferred replacement for new designs and ongoing production. Packaging is supplied in tube format.

Primary Substitutes - Molex C-Grid 70247 Series

The Molex parts 0702474051, 0702474052, and 0702474054 meet all core substitution criteria. These parts are active, ROHS3 compliant, and maintain identical pitch, position count, and mounting configuration. Minor dimensional variations exist in contact length (0.240" vs. 0.236") and insulation height (0.350" vs. 0.362"), which remain within acceptable tolerance for standard PCB applications. Fastening type remains Push-Pull. Packaging options include Bulk and Tray formats.

Secondary Substitutes - HARTING SEK Series

The HARTING parts 09185405323, 09185406323, and 09185407323 provide functional equivalence with alternative fastening mechanism (Latch Holder vs. Push-Pull). These parts are active and ROHS3 compliant. Contact length and insulation height specifications differ slightly (0.242" and 0.366" respectively). Operating temperature range is specified at -55°C to 125°C. These parts are suitable for applications where latch-based mating is acceptable.

Secondary Substitute - TE Connectivity 3-1761605-3

The TE Connectivity AMP-Latch series part 3-1761605-3 maintains core dimensional and electrical compatibility. This part is active and ROHS3 compliant with specified operating temperature range of -65°C to 105°C and current rating of 1A per contact at 250VAC. Fastening type is Push-Pull. Insulation material is PBT without glass fill specification.

Alternative Substitute - Samtec HTST-120-04-F-D-LA

The Samtec Flex Stack HTST series part HTST-120-04-F-D-LA provides functional substitution with kinked pin termination and Liquid Crystal Polymer insulation material. This part is active and ROHS3 compliant with operating temperature range of -55°C to 125°C and current rating of 3.4A per contact. Contact length is 0.250" (6.35mm), representing the longest mating contact among substitute options.

Frequently Asked Questions (FAQ)

Q: Can the 75867-307LF directly replace the obsolete 75867-307 without PCB redesign?

A: Yes. The 75867-307LF is dimensionally and functionally identical to the 75867-307. Both parts share the same pitch (2.54mm), position count (40), row spacing (2.54mm), mounting type (through-hole right-angle), and contact specifications. The primary difference is RoHS compliance status. No PCB layout modifications are required.

Q: What are the key differences between Amphenol and Molex substitutes?

A: Amphenol 75867-307LF and Molex C-Grid 70247 series (0702474051, 0702474052, 0702474054) maintain identical core specifications. Molex parts exhibit slightly longer mating contact length (0.240" vs. 0.236") and reduced insulation height (0.350" vs. 0.362"). Both use Push-Pull fastening and are RoHS compliant. Packaging differs: Amphenol supplies tube format; Molex offers bulk and tray options.

Q: Are HARTING parts with Latch Holder fastening compatible with existing mating connectors designed for Push-Pull?

A: HARTING SEK series parts (09185405323, 09185406323, 09185407323) use Latch Holder fastening instead of Push-Pull. These parts are not directly compatible with existing mating connectors designed for Push-Pull fastening. Mating connector replacement is required if HARTING parts are selected.

Q: What packaging options are available for substitute parts?

A: Amphenol 75867-307LF is supplied in tube packaging. Molex C-Grid 70247 series offers bulk and tray formats. HARTING SEK series is supplied in bulk packaging. Samtec HTST series packaging is not specified in available documentation. Packaging selection should align with production volume and handling requirements.

Q: Do all substitute parts meet UL94 V-0 flammability requirements?

A: Yes. All substitute parts listed—Amphenol 75867-307LF, Molex C-Grid 70247 series, HARTING SEK series, TE Connectivity 3-1761605-3, and Samtec HTST-120-04-F-D-LA—carry UL94 V-0 material flammability certification, matching the original 75867-307 specification.

Q: Which substitute offers the widest operating temperature range?

A: TE Connectivity 3-1761605-3 specifies -65°C to 105°C operating temperature range. HARTING SEK series and Samtec HTST series specify -55°C to 125°C. The original 75867-307 does not specify operating temperature limits. Temperature range selection should align with application requirements.

Q: Are there RoHS compliance considerations when selecting substitutes?

A: The original 75867-307 is RoHS non-compliant. All active substitute parts are RoHS compliant (75867-307LF is RoHS Compliant; Molex, HARTING, TE Connectivity, and Samtec parts are ROHS3 Compliant). For new designs and applications subject to RoHS regulations, any substitute part is acceptable. For legacy system maintenance where RoHS non-compliant parts are required, the original 75867-307 remains the only option.

Q: What is the significance of contact finish thickness variations among substitutes?

A: Contact finish thickness affects durability and mating cycle performance. The original 75867-307 specifies 15.0µin (0.38µm) gold finish on mating contacts. Molex 0702474051 matches this specification; 0702474052 specifies 30.0µin (0.76µm); 0702474054 specifies 5.00µin (0.127µm). Thicker finishes generally provide extended contact life. Selection should align with expected mating cycle requirements and environmental exposure.
