Engineering Selection Recommendations
Primary Substitutes (Exact Post Length Match - 0.120"):
The 3M 2326-6121-TG and 2326-6121TB are direct mechanical and electrical equivalents with identical contact post length (0.120"). Both are active products from a major connector manufacturer. The 3M parts maintain the same 26-position, 2-row configuration with 0.100" pitch and push-pull fastening. However, the 3M parts operate at -55°C to 105°C, which is narrower than the original -65°C to 130°C range. Selection of 3M parts is appropriate for applications within the -55°C to 105°C window.
Secondary Substitutes (Extended Post Length - Sullins PBC13 Series):
The Sullins Connector Solutions PBC13DAAN through PBC13DAHN series provides active, ROHS3-compliant alternatives with identical mating contact length (0.230") and core electrical specifications. These parts differ in contact post length, ranging from 0.120" (PBC13DAAN) to 0.820" (PBC13DAHN). The PBC13DAAN is the closest match to the original 67997-526, with identical post length and extended operating temperature range (-65°C to 125°C). The extended post length variants (PBC13DABN through PBC13DAHN) are suitable for applications requiring deeper board-to-board spacing or longer solder tail engagement.
All Sullins PBC13 variants feature phosphor bronze contacts matching the original material specification and achieve ROHS3 compliance, addressing environmental regulatory requirements not met by the original part.
Compliance Considerations:
The original 67997-526 is RoHS non-compliant. For new designs or applications subject to RoHS requirements, the Sullins PBC13 series provides compliant alternatives. The 3M 2300 series remains non-compliant and is suitable only for legacy applications or regions without RoHS mandates.
Inventory and Availability:
All substitute parts listed are in active production with substantial inventory levels, ensuring long-term procurement stability compared to the obsolete 67997-526.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with a different contact post length?
A: Yes, if your board design accommodates the different overall contact length. The contact post length determines the depth of solder tail engagement and board-to-board spacing. Verify that the substitute part's overall contact length (mating contact length plus post length) is compatible with your PCB thickness and mating connector depth. The PBC13DAAN (0.120" post) is a direct replacement for the 67997-526. Extended post variants require board design verification.
Q: Are the 3M 2326 series parts direct replacements?
A: The 3M 2326-6121-TG and 2326-6121TB are mechanically and electrically compatible with identical contact post length (0.120"). However, their operating temperature range (-55°C to 105°C) is narrower than the original (-65°C to 130°C). Use 3M parts only if your application operates within the -55°C to 105°C window.
Q: What is the difference between the Sullins PBC13 variants?
A: All PBC13 variants share identical mating specifications (26 positions, 2 rows, 0.100" pitch, 0.230" mating contact length). They differ only in contact post length: PBC13DAAN (0.120"), PBC13DABN (0.230"), PBC13DACN (0.320"), PBC13DADN (0.420"), PBC13DAEN (0.520"), PBC13DAFN (0.620"), and PBC13DAHN (0.820"). Select based on your required board-to-board spacing and solder tail length.
Q: Does the contact material difference affect compatibility?
A: The original 67997-526 uses phosphor bronze contacts. The 3M 2326 series uses copper alloy contacts. Both materials are acceptable for this connector class and maintain equivalent electrical performance and current rating (3A). The Sullins PBC13 series matches the original phosphor bronze specification. Material selection does not affect mechanical or electrical compatibility.
Q: Are the substitute parts RoHS compliant?
A: The Sullins PBC13 series is ROHS3 compliant. The 3M 2326 series and original 67997-526 are RoHS non-compliant. For applications subject to RoHS requirements, specify a Sullins PBC13 variant.
Q: Can I mix substitute parts in the same design?
A: Yes, all listed substitutes are mechanically and electrically interchangeable within the constraints of contact post length and operating temperature range. However, for consistency and supply chain management, specify a single part number per design.
Q: What is the significance of the contact finish thickness variation?
A: The original 67997-526 specifies 15.0µin (0.38µm) gold finish on mating contacts. Substitute parts vary from 10.0µin (0.25µm) to 30.0µin (0.76µm). All values provide adequate corrosion protection and electrical conductivity for the 3A current rating. Thicker finishes (30.0µin on 2326-6121TB) offer extended contact life in high-cycle mating applications.
