Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC 68690-450HLF

The 68690-450HLF is the direct successor to the obsolete 67999-450HLF within the same manufacturer and series. This part maintains identical mechanical and electrical specifications while offering active product status, RoHS compliance, and an extended operating temperature range (-65°C to 130°C). The 68690-450HLF is the preferred choice for direct replacement in new designs and production continuity.

Secondary Recommendations: 3M 929710 Series

The 3M 929710 series provides multiple contact length options to accommodate different PCB stack-up requirements:

929710-01-25-RK: Standard contact length (0.110" post), RoHS compliant, active status. Suitable for standard board-to-board spacing.
929710-10-25-RK: Extended contact length (0.175" post), RoHS compliant, active status. Suitable for applications requiring greater mating depth.
929710-11-25-RK: Intermediate contact length (0.125" post), RoHS compliant, active status. Suitable for moderate stack-up applications.
929710-06-25-RK: Extended post length (0.710"), RoHS compliant, active status. Suitable for specialized applications with significant PCB separation.

All 3M 929710-RK variants feature tin contact finish with enhanced thickness (200.0µin), PCT insulation material, and RoHS compliance.

Alternative: TE Connectivity 7-146252-5

The TE Connectivity 7-146252-5 (AMPMODU Mod II series) offers gold-plated mating contacts (15.0µin thickness) with LCP insulation material. This part is suitable for applications requiring enhanced corrosion resistance and is RoHS compliant with active product status. Operating temperature range is -65°C to 105°C with 3A current rating.

Alternative: 3M 929715-01-25-EU

The 929715-01-25-EU features gold plating on both mating and post contacts (10.0µin thickness) with PCT insulation. This variant is RoHS compliant and active, suitable for applications requiring superior contact reliability and corrosion resistance.

Discontinued Parts: 929710-01-25 and 929710-10-25

These 3M variants are discontinued at DiGi Electronics and feature tin-lead contact finish with PBT insulation. RoHS non-compliant status and discontinuation status make these unsuitable for new designs. Use only for legacy system maintenance where RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the 67999-450HLF?

A: All listed substitute parts share identical mating pitch (0.100"), position count (50), row configuration (2), and fastening mechanism (push-pull). Mechanical compatibility is confirmed for board-to-board mating. However, contact post length varies across substitutes, which affects overall connector height. Verify PCB stack-up clearance before selection.

Q: What is the difference between the 929710-01-25-RK and 929710-10-25-RK?

A: Both are 3M 929710 series connectors with identical mating characteristics. The primary difference is contact post length: 929710-01-25-RK has 0.110" (2.79mm) post length, while 929710-10-25-RK has 0.175" (4.45mm) post length. Select based on required PCB separation distance.

Q: Is RoHS compliance required for my application?

A: RoHS compliance status varies across substitutes. The 68690-450HLF, 7-146252-5, 929710-01-25-RK, 929710-06-25-RK, 929710-10-25-RK, 929710-11-25-RK, and 929715-01-25-EU are all RoHS compliant. The 929710-01-25, 929710-10-25, and 929710-11-25 are RoHS non-compliant. Verify regulatory requirements for your end application.

Q: What is the difference between tin and gold contact finishes?

A: Tin-finished contacts (929710 series) provide standard corrosion resistance and cost efficiency. Gold-finished contacts (7-146252-5 and 929715-01-25-EU) offer enhanced corrosion resistance and lower contact resistance, suitable for high-reliability applications. Gold finish thickness varies: 7-146252-5 uses 15.0µin, while 929715-01-25-EU uses 10.0µin.

Q: What packaging options are available?

A: The 68690-450HLF is supplied in bag packaging. The 7-146252-5, 929710 series, and 929715-01-25-EU are supplied in bulk packaging. The original 67999-450HLF packaging is not specified.

Q: What is the operating temperature range for each substitute?

A: The 68690-450HLF operates from -65°C to 130°C. The 7-146252-5 operates from -65°C to 105°C. All 3M 929710 and 929715 series operate from -40°C to 105°C. Select based on thermal environment requirements.

Q: Are there current rating differences between substitutes?

A: The 68690-450HLF and 7-146252-5 are rated for 3A. All 3M 929710 and 929715 series are rated for 2.5A. Verify current requirements for your application.

Q: What is the difference between PBT and PCT insulation materials?

A: PBT (Polybutylene Terephthalate) is a standard engineering plastic used in 929710-01-25, 929710-10-25, and 929710-11-25. PCT (Polycyclohexylenedimethylene Terephthalate) is a higher-performance variant used in 929710-01-25-RK, 929710-06-25-RK, 929710-10-25-RK, 929710-11-25-RK, and 929715-01-25-EU. LCP (Liquid Crystal Polymer) is used in 7-146252-5. All materials meet UL94 V-0 flammability requirements.
