Engineering Selection Recommendations

Primary Selection - Active Status with RoHS Compliance:

For new designs requiring RoHS3 compliance matching the original Molex 0010897123, the 3M 929665 series (929665-01-06-I, 929665-02-06-I, 929665-03-06-I, 929665-08-06-I, 929665-09-06-I) provides direct functional equivalence. These parts maintain the 12-position, 2-row, 2.54mm pitch configuration with gold-plated mating contacts and operate across the -40°C to 105°C temperature range. Selection within this series is determined by post-length requirements for specific PCB stack-up depths.

Alternative with Enhanced Temperature Range:

The TE Connectivity 87227-6 (AMPMODU Mod II series) extends the operating temperature range to -65°C to 105°C and provides gold plating on both mating and post contacts. This part is suitable for applications requiring wider temperature performance, though RoHS status is listed as not applicable.

Tin-Plated Contact Finish Options:

The 3M 929836-01-06-RK and 929836-02-06-RK variants provide tin-plated contact finishes with RoHS compliance. These are functionally equivalent to the original part's tin-plated post finish and are available in different post-length configurations.

Discontinued Parts:

The 3M 929836-04-06 is discontinued at DiGi Electronics and should not be selected for new designs, despite remaining in inventory. The 3M 929836-02-06 carries RoHS non-compliant status due to tin-lead contact finish and should be avoided in applications requiring RoHS certification.

Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the Molex 0010897123?

A: The core substitution criteria are: 12 positions in a 2-row configuration, 0.100" (2.54mm) mating pitch and row spacing, male pin contacts, through-hole solder termination, push-pull fastening, square contact shape, and UL94 V-0 flammability rating. Variations in contact finish, insulation material, post length, and operating temperature do not prevent substitution if the application requirements are met.

Q: Why are there multiple 3M 929665 part numbers with different suffixes?

A: The 929665 series variants (01-06-I, 02-06-I, 03-06-I, 08-06-I, 09-06-I) differ in post length to accommodate different PCB stack-up depths. The post length determines the overall contact length and is selected based on the specific application's board thickness and mating connector depth requirements. All variants maintain identical mating contact length (0.235") and insulation height (0.100").

Q: Is the TE Connectivity 87227-6 compatible with the Molex 0010897123?

A: Yes. The 87227-6 maintains the same 12-position, 2-row, 2.54mm pitch configuration and male pin contact type. The primary differences are the extended operating temperature range (-65°C to 105°C versus unspecified for the Molex part), gold plating on both mating and post contacts, and thermoplastic insulation material. These differences do not prevent functional compatibility in standard applications.

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

A: Gold plating provides superior corrosion resistance and lower contact resistance, making it suitable for low-signal applications and environments with potential corrosion exposure. Tin plating is cost-effective and suitable for general-purpose applications with adequate environmental protection. The Molex 0010897123 uses gold-plated mating contacts with tin-plated posts. Substitute parts with all-gold plating (929665 series) or all-tin plating (929836-01-06-RK, 929836-02-06-RK) are functionally equivalent if the application does not require the specific mixed-finish configuration.

Q: Are there RoHS compliance considerations when selecting a substitute?

A: Yes. The original Molex 0010897123 is ROHS3 compliant. Most 3M 929665 and 929836-RK variants are RoHS compliant. The 3M 929836-02-06 and 929836-04-06 are RoHS non-compliant due to tin-lead contact finish and should not be used in applications requiring RoHS certification. The TE Connectivity 87227-6 lists RoHS status as not applicable.

Q: Can I use a substitute part with a different post length?

A: Yes, if the application accommodates the different overall contact length. Post length variations (0.110" to 0.510") are selected based on PCB thickness and mating connector depth. Verify that the substitute part's post length does not exceed the available space in your application's stack-up configuration.

Q: What is the current rating difference between parts?

A: The Molex 0010897123 does not specify a current rating. The 3M 929665 and 929836 series are rated for 2.5A, while the TE Connectivity 87227-6 is rated for 3A. These ratings indicate the maximum continuous current the connector can safely carry. For applications requiring higher current capacity, the TE Connectivity part provides a 0.5A advantage, though this difference is typically negligible in standard signal-level applications.
