Substitute Part Grouping Explanation

Substitution for the 71922-026 is determined by strict equivalence across the following critical parameters:

Primary Matching Criteria:

Connector type (Header), contact type (Male Pin), and configuration (26 positions, 2 rows)
Pitch and row spacing (0.100" / 2.54mm)
Mounting style (Through Hole, Right Angle)
Shrouding design (Shrouded – 4 Wall)
Termination method (Solder) and fastening type (Push-Pull)
Contact finish at mating surface (Gold)
Flammability rating (UL94 V-0)
Moisture sensitivity level (1 – Unlimited)

Secondary Considerations:

Contact length variations (mating and post lengths) within acceptable mechanical tolerances
Insulation material composition (thermoplastic or polyester variants)
Insulation color (gray or black)
Contact material (phosphor bronze, copper alloy, or brass)
Operating temperature range
RoHS and REACH compliance status
Product status (active vs. obsolete)

Substitutes are grouped by manufacturer and series. All listed parts maintain functional and mechanical compatibility with the original 71922-026 specification.

Engineering Selection Recommendations

Direct Replacement (Same Manufacturer): The 71922-026LF from Amphenol ICC (FCI) is the direct active equivalent. It maintains identical mechanical and electrical specifications to the original 71922-026 while offering RoHS compliance and improved product status. This part is recommended for applications requiring minimal design validation.

Active Alternatives with Enhanced Compliance: The 3M N3429-5002RB and N3429-5003RB, along with the 3M D3429-5002-AR, provide active product status with ROHS3 compliance. These parts offer higher current ratings (1.75A) and defined operating temperature ranges (-55°C to 105°C), making them suitable for applications with stricter regulatory requirements. The primary difference between N3429-5002RB and N3429-5003RB is post contact length (0.112" vs. 0.155"), which affects board thickness compatibility.

HARTING SEK Series: The HARTING 09185266921, 09185266923, 09185267921, and 09185267923 connectors provide ROHS3 compliance and extended operating temperature range (-55°C to 125°C). These parts feature slightly longer mating contact length (0.240" vs. 0.228") and are available with two post length options (0.114" or 0.177"), allowing flexibility for different PCB thicknesses.

TE Connectivity AMP-Latch: The TE Connectivity 102160-6 offers defined electrical ratings (1A per contact, 250VAC) and operating temperature range (-65°C to 105°C). This part is suitable for applications requiring explicit current and voltage specifications. Note that this part does not carry RoHS compliance.

Obsolete Parts: The 3M 3429-5002 and original 71922-026 are obsolete. While inventory may be available, new designs should transition to active alternatives.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 71922-026 with the 71922-026LF? A: Yes. The 71922-026LF is the direct active equivalent from the same manufacturer. It maintains identical pitch (2.54mm), position count (26), contact configuration, and mechanical dimensions. The primary difference is RoHS compliance status and active product status.

Q: What is the difference between HARTING parts 09185266923 and 09185267923? A: Both are HARTING SEK series connectors with identical specifications except for post contact length. The 09185266923 has 0.114" post length, while the 09185267923 has 0.177" post length. Selection depends on PCB thickness and solder pad depth requirements.

Q: Are the 3M N3429-5002RB and N3429-5003RB interchangeable? A: Both parts are mechanically and electrically compatible with the 71922-026. The difference is post contact length: N3429-5002RB has 0.112" and N3429-5003RB has 0.155". Choose based on your PCB thickness and soldering requirements.

Q: Does the TE Connectivity 102160-6 require different PCB layout than the 71922-026? A: The 102160-6 has a slightly shorter insulation height (0.315" vs. 0.339") and different post contact length (0.110"). Verify PCB pad spacing and solder pocket depth compatibility before substitution.

Q: Which substitute part offers the widest operating temperature range? A: The HARTING SEK series (09185266921, 09185266923, 09185267921, 09185267923) provides the widest operating temperature range of -55°C to 125°C, compared to the original 71922-026 which does not specify an operating temperature range.

Q: Are all substitute parts RoHS compliant? A: No. The TE Connectivity 102160-6 and original 71922-026 are not RoHS compliant. The 71922-026LF, HARTING SEK series, 3M D3429-5002-AR, 3M N3429-5002RB, and 3M N3429-5003RB all carry RoHS or ROHS3 compliance.

Q: What packaging options are available for these connectors? A: Packaging varies by part number. The 71922-026LF is supplied in tubes, while most HARTING and 3M alternatives are supplied in bulk or trays. Verify packaging requirements for your procurement and assembly processes.

Q: Can I use the 3M 3429-5002 as a substitute despite its obsolete status? A: While the 3429-5002 is functionally compatible, it is classified as obsolete. Existing inventory may be available, but new designs should transition to active alternatives such as N3429-5002RB or D3429-5002-AR to ensure long-term supply chain stability.
