Engineering Selection Recommendations

146140-2 (TE Connectivity AMP Connectors): This connector is suitable for applications where gold-plated mating contacts are required and RoHS non-compliance is acceptable. The tin-lead post finish and polyester insulation material provide established performance characteristics. Product status is active with established supply availability.

89883-303LF (Amphenol ICC Dubox™): This substitute offers RoHS compliance and REACH affected status, making it suitable for applications with regulatory compliance requirements. The gold-plated mating contacts match the original specification. The thermoplastic insulation material and blue insulation color provide differentiation. Current rating is not specified; applications include automotive, general purpose, industrial, and telecommunications sectors.

BCS-103-S-D-HE (Samtec Tiger Claw™ BCS): This substitute provides ROHS3 compliance and REACH unaffected status. Gold-plated mating contacts are maintained. The liquid crystal polymer insulation material offers enhanced thermal and mechanical properties. Higher current rating (4.6A per contact) and voltage rating (475VAC) exceed the original specification. Operating temperature range matches the original (-55°C ~ 125°C).

BCS-103-T-D-HE (Samtec Tiger Claw™ BCS): This substitute provides ROHS3 compliance and REACH unaffected status with tin-plated mating contacts. The liquid crystal polymer insulation material and higher current/voltage ratings match the BCS-103-S-D-HE variant. Operating temperature range matches the original specification. Selection of this variant is appropriate when tin contact finish is preferred over gold.

M20-7880346 (Harwin M20): This substitute provides ROHS3 compliance and REACH unaffected status with tin-plated mating contacts. The polyamide (PA6T) nylon 6T insulation material provides alternative thermal characteristics. Operating temperature range is -40°C ~ 105°C, which is narrower than the original. Current rating (3A) and voltage rating (1000V) exceed the original specification. Applications include general purpose, industrial, and telecommunications sectors.

Frequently Asked Questions (FAQ)

Q: Can the 146140-2 be directly replaced with any of these substitute parts?

A: All identified substitute parts maintain the critical mechanical and electrical parameters: 6-position, 2-row configuration with 0.100" (2.54mm) pitch, through-hole right-angle mounting, solder termination, push-pull fastening, phosphor bronze contacts with square shape, and UL94 V-0 flammability rating. Direct replacement is mechanically and electrically feasible. However, compliance requirements, contact finish specifications, and operating temperature ranges must be evaluated for specific applications.

Q: What is the primary difference between the gold-plated and tin-plated variants?

A: The 146140-2 and 89883-303LF feature gold-plated mating contacts (10.0µin and 30.0µin thickness respectively), while BCS-103-T-D-HE and M20-7880346 feature tin-plated mating contacts. Gold plating provides superior corrosion resistance and lower contact resistance, while tin plating offers cost efficiency. Selection depends on application environment and performance requirements.

Q: Are there compliance differences between these parts?

A: The 146140-2 is RoHS non-compliant with vendor-undefined REACH status. All substitute parts are RoHS compliant (either RoHS or ROHS3). The 89883-303LF is REACH affected, while BCS-103-S-D-HE, BCS-103-T-D-HE, and M20-7880346 are REACH unaffected. Applications requiring RoHS or REACH compliance must select appropriate substitutes accordingly.

Q: How do the operating temperature ranges compare?

A: The 146140-2, BCS-103-S-D-HE, and BCS-103-T-D-HE operate across -55°C ~ 125°C. The M20-7880346 operates across -40°C ~ 105°C, providing a narrower temperature range. The 89883-303LF does not specify an operating temperature range. Applications requiring full -55°C ~ 125°C operation should select from the first three options.

Q: What are the current and voltage rating differences?

A: The 146140-2 specifies 2A current rating with unspecified voltage rating. The 89883-303LF does not specify current or voltage ratings. The BCS-103-S-D-HE and BCS-103-T-D-HE both specify 4.6A per contact and 475VAC. The M20-7880346 specifies 3A and 1000V. Applications with higher current or voltage requirements should select BCS or M20 variants.

Q: What packaging options are available?

A: The 146140-2 packaging is not specified. The 89883-303LF is supplied in tube packaging. The BCS-103-S-D-HE is supplied in bulk packaging. The BCS-103-T-D-HE and M20-7880346 are supplied in tube packaging. Packaging selection may influence procurement and handling procedures.

Q: How do the insulation materials differ?

A: The 146140-2 uses polyester with glass fill. The 89883-303LF uses thermoplastic with glass fill. The BCS-103-S-D-HE and BCS-103-T-D-HE use liquid crystal polymer (LCP) with glass fill. The M20-7880346 uses polyamide (PA6T) nylon 6T. Insulation material selection influences thermal performance, mechanical properties, and chemical resistance.

Q: Are there inventory considerations for these substitutes?

A: The 146140-2 has 658 pieces in stock. The 89883-303LF has 1130 pieces. The BCS-103-S-D-HE has 1059 pieces. The BCS-103-T-D-HE has 701 pieces. The M20-7880346 has 2235 pieces. Inventory levels may influence procurement decisions for time-sensitive applications.
