Engineering Selection Recommendations

TE Connectivity 3-826646-2 and 3-826936-2

Both TE Connectivity AMPMODU Mod II series connectors are active products with ROHS3 compliance and higher current ratings (5A) than the 3M original. The 3-826646-2 features gold mating contacts, while the 3-826936-2 provides tin mating contacts. Both support the extended operating temperature range of -65°C to 105°C. These parts are suitable for applications requiring RoHS compliance and higher current capacity.

Preci-Dip 890-18-032-10-002101

This connector maintains the same contact shape (square) and current rating (3A) as the 3M 2332-6211-TG. It offers an extended operating temperature range to 125°C and ROHS3 compliance. The Preci-Dip series is appropriate for applications requiring higher temperature operation and RoHS certification.

Samtec BBS-132-G-A and BBS-132-T-A

Both Samtec BBS series connectors feature circular contact shapes and extended operating temperature range (-55°C to 125°C). The BBS-132-G-A provides gold mating contacts, while the BBS-132-T-A offers tin mating contacts. These parts are ROHS3 compliant. Note that contact shape differs from the original (circular vs. square), which may affect mating compatibility with existing receptacles.

Harwin D01-9923246

This SIP/SIL header connector is ROHS3 compliant with tin contact finish and unlimited moisture sensitivity. It is suitable for applications where RoHS compliance is required and tin plating is acceptable.

Harwin M20-9993245

The M20 series connector is a cuttable header with gold mating contacts, ROHS3 compliance, and a 3A current rating. It maintains the square contact shape and is suitable for applications requiring modular or customizable connector configurations.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different contact shape (circular vs. square)?

A: Contact shape affects mating compatibility with receptacles. Samtec BBS-132-G-A and BBS-132-T-A feature circular contacts, while the 3M original and most other substitutes use square contacts. Verify that your mating receptacle is compatible with the selected contact geometry before substitution.

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

A: Gold provides superior corrosion resistance and lower contact resistance, while tin offers cost efficiency. Both finishes are suitable for standard applications. Select based on environmental requirements and cost considerations.

Q: Are all substitute parts RoHS compliant?

A: The 3M 2332-6211-TG is RoHS non-compliant. All listed substitute parts are ROHS3 compliant. If RoHS compliance is required for your application, any of the substitute parts are suitable.

Q: What is the significance of the operating temperature range difference?

A: The 3M original operates from -55°C to 105°C. TE Connectivity, Preci-Dip, and Samtec substitutes extend the upper limit to 125°C, providing additional thermal margin. Harwin M20-9993245 operates from -40°C to 105°C, which is narrower at the lower end. Select based on your application's thermal requirements.

Q: Can I substitute a 5A-rated connector for a 3A-rated application?

A: Yes. Higher current ratings provide additional design margin and are suitable for applications rated at lower currents. TE Connectivity 3-826646-2 and 3-826936-2 both support 5A, making them suitable for 3A applications.

Q: What packaging options are available?

A: Substitute parts are available in Bulk (TE Connectivity, Preci-Dip, Harwin) or Tube (Samtec) packaging. Verify packaging compatibility with your procurement and assembly processes.

Q: Are cuttable or breakaway connector variants compatible with standard receptacles?

A: Cuttable and breakaway variants maintain the same pitch and contact geometry as standard headers, making them compatible with standard receptacles. These variants offer design flexibility for applications requiring modular configurations.
