Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The Molex C-Grid 70280 series (part numbers 0010897260, 0010897261, 0010897262) and Molex C-Grid 87914 series (part number 0879142616) provide direct functional equivalence to the TE Connectivity 146220-5. These components are active products with ROHS3 compliance, addressing the obsolescence and regulatory status of the original part. The Molex parts maintain identical pitch, position count, row configuration, and mounting characteristics. Contact length variations are within acceptable mating tolerances for standard PCB applications.

Secondary Substitutes (Functional Equivalence with Minor Variations):

The Amphenol ICC/FCI BERGSTIK® II series (part numbers 67996-126HLF, 67996-226HLF, 67996-426HLF, 67997-126HLF) offers functional compatibility with enhanced operating temperature ranges (-65°C to 125°C or 130°C). These components feature phosphor bronze contacts and are RoHS compliant. The insulation height is 0.100" compared to the original 0.090", which remains compatible with standard board-to-board spacing. Contact post lengths vary but remain within acceptable ranges for solder termination.

Alternative Substitute (Different Insulation Material):

The 3M 2300 Series (part number 2326-6121-TG) provides functional equivalence with thermoplastic glass-filled insulation material. This part maintains the 3A current rating and operates within the -55°C to 105°C temperature range. The insulation height of 0.100" is compatible with standard applications. This part is active but retains RoHS non-compliant status, similar to the original component.

Compliance Considerations:

For applications requiring RoHS compliance, the Molex C-Grid series and Amphenol BERGSTIK® II series are recommended. For legacy systems where RoHS compliance is not mandated, the 3M 2300 Series provides an alternative. All substitute parts maintain UL94 V-0 flammability ratings and are suitable for general purpose, automotive, lighting, medical, and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0010897260 directly replace the TE Connectivity 146220-5 in existing designs?

A: Yes. The Molex 0010897260 maintains identical pitch (0.100"), position count (26), row configuration (2), mounting type (through-hole), and termination method (solder). The contact length variations are within acceptable mating tolerances for standard PCB applications. The primary advantage is active product status and ROHS3 compliance.

Q: What is the difference between Molex part numbers 0010897260, 0010897261, and 0010897262?

A: These three parts differ in contact finish specifications. The 0010897260 features gold-plated mating contacts. The 0010897261 has tin-plated mating contacts. The 0010897262 has gold-plated mating contacts with reduced thickness (15.0µin). All three maintain identical dimensional and electrical characteristics. Selection depends on application-specific contact finish requirements.

Q: Why do some substitute parts have different insulation heights (0.100" vs. 0.090")?

A: Insulation height variations reflect different design standards across manufacturers. The 0.100" insulation height used by Amphenol and 3M is compatible with standard board-to-board spacing applications. The 0.010" difference does not affect mating compatibility or electrical performance in typical PCB layouts.

Q: Are the Amphenol BERGSTIK® II parts suitable for high-temperature applications?

A: Yes. The Amphenol BERGSTIK® II series (67996-126HLF, 67996-226HLF, 67996-426HLF, 67997-126HLF) operates across -65°C to 125°C or -65°C to 130°C temperature ranges, exceeding the original TE part's -65°C to 105°C specification. These parts are suitable for applications requiring extended temperature performance.

Q: What packaging options are available for these substitute parts?

A: Packaging varies by manufacturer and part number. Molex C-Grid series parts are supplied in bulk packaging. Amphenol BERGSTIK® II parts are supplied in bag packaging. Molex C-Grid 87914 series is supplied in tray packaging. Selection of packaging type depends on assembly process requirements and inventory management practices.

Q: Do all substitute parts maintain the 3A current rating?

A: The TE Connectivity 146220-5, 3M 2326-6121-TG, and Amphenol BERGSTIK® II series explicitly specify 3A current rating. Molex C-Grid series parts do not specify current rating in the provided data. For applications requiring confirmed 3A current capacity, the Amphenol or 3M parts are recommended.

Q: Which substitute part offers the best RoHS compliance status?

A: The Molex C-Grid 70280 series (0010897260, 0010897261, 0010897262) and Molex C-Grid 87914 series (0879142616) are ROHS3 compliant. The Amphenol BERGSTIK® II series is RoHS compliant. The 3M 2300 Series retains RoHS non-compliant status. For new designs requiring RoHS compliance, Molex or Amphenol parts are recommended.

Q: Can the Molex 0702871109 with kinked pin termination replace the standard solder termination parts?

A: The Molex 0702871109 features kinked pin termination in addition to solder termination, providing alternative assembly options. This part maintains all other dimensional and electrical specifications. Selection depends on whether kinked pin termination is compatible with the assembly process and PCB design.

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

A: Gold-plated contacts (0010897260, 0010897262, 67996-126HLF, 67996-226HLF, 67997-126HLF) provide superior corrosion resistance and lower contact resistance. Tin-plated contacts (0010897261, 0879142616, 67996-426HLF) offer cost advantages and adequate performance for standard applications. Selection depends on environmental exposure and electrical performance requirements.

Q: Are substitute parts available with different contact materials?

A: Yes. The TE Connectivity 146220-5 uses copper alloy contacts. Amphenol BERGSTIK® II parts use phosphor bronze contacts, which provide enhanced durability and contact reliability. Molex and 3M parts use copper alloy contacts. Contact material selection depends on application-specific durability and performance requirements.
