Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: 26-position count, 2-row configuration, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, through-hole mounting, solder termination, unshrouded design, and board-to-board or board-to-cable style compatibility. All identified substitutes maintain these electrical and mechanical specifications. Variations in contact length, insulation height, contact finish composition, and material flammability rating do not preclude substitution within the rectangular connector category, provided the mating interface and pitch geometry remain constant. Contact finish thickness, post length, and insulation material differences are acceptable where application thermal and environmental requirements do not mandate specific performance thresholds.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and are suitable for direct replacement in applications where the 26-position, 2-row, 0.100" (2.54mm) pitch configuration is required. Selection among substitutes depends on compliance requirements and environmental specifications.

For applications requiring RoHS3 compliance, the following parts are suitable: TE Connectivity 6-146252-3, Samtec BBD-113-G-B, Samtec MTSW-113-22-G-D-365, and all Sullins Connector Solutions variants (PBC13DFAN, PBC13DFBN, PBC13DFEN, PEC13DFAN, PEC13DFCN).

For applications requiring RoHS compliance without RoHS3 designation, 3M 929715-01-13-EU is suitable. TE Connectivity 87215-9 carries "Not applicable" RoHS status and is suitable where RoHS compliance is not mandated.

For applications requiring extended operating temperature range (-55°C to 125°C), Samtec BBD-113-G-B and Samtec MTSW-113-22-G-D-365 are specified. All Sullins variants support -65°C to 125°C operation.

For applications with standard operating temperature requirements (-40°C to 105°C or -65°C to 105°C), all remaining substitutes are suitable.

Contact post length variations accommodate different PCB thicknesses and stacking heights. Standard post lengths (0.110" to 0.165") are provided by most substitutes. Extended post lengths (0.220" to 0.520") are available from Sullins variants for applications requiring deeper board penetration or additional stacking capability.

Frequently Asked Questions (FAQ)

Q: Can the 68691-126 be directly replaced with any of the listed substitutes?

A: Yes, all listed parts maintain the core mating specifications: 26 positions, 2 rows, 0.100" (2.54mm) pitch, and 0.100" (2.54mm) row spacing. Direct mechanical and electrical compatibility is established for board-to-board applications. Verify post length and insulation height compatibility with your PCB design before final selection.

Q: What is the primary difference between the Amphenol ICC 68691-126 and TE Connectivity 6-146252-3?

A: The primary differences are RoHS compliance status (68691-126 is non-compliant; 6-146252-3 is ROHS3 compliant), contact finish thickness on the mating surface (30.0µin versus 15.0µin), and insulation material (unspecified versus Liquid Crystal Polymer). Mating pitch, position count, and electrical interface are identical.

Q: Are there contact finish differences that affect substitution?

A: Yes. The 68691-126 features gold or gold GXT™ finish on mating contacts. Substitutes vary: TE Connectivity and 3M parts use gold finish; Samtec parts use gold finish; Sullins PBC variants use gold mating finish with tin post finish; Sullins PEC variants use tin mating finish. Gold-finished mating contacts (68691-126, 6-146252-3, 87215-9, 929715-01-13-EU, BBD-113-G-B, MTSW-113-22-G-D-365, PBC13DFAN, PBC13DFBN, PBC13DFEN) are preferred for corrosion resistance in standard environments. Tin-finished mating contacts (PEC13DFAN, PEC13DFCN) are suitable for cost-sensitive applications where corrosion protection is secondary.

Q: What post length should I select for my application?

A: Post length determines how far the connector extends into the PCB. Standard post lengths (0.110" to 0.165") are suitable for single-board applications. Extended post lengths (0.220" to 0.520") accommodate stacked board configurations or applications requiring deeper mechanical engagement. Verify your PCB thickness and stacking requirements before selection.

Q: Does insulation material affect substitution compatibility?

A: Insulation material does not affect mating compatibility but influences thermal and chemical resistance. Liquid Crystal Polymer (LCP) offers superior thermal performance; Polybutylene Terephthalate (PBT) provides standard performance at lower cost; Thermoplastic and Polyester Glass Filled materials offer intermediate performance. All materials meet UL94 V-0 flammability requirements. Select based on operating temperature and environmental exposure requirements.

Q: Are all substitutes suitable for RoHS-regulated applications?

A: No. The 68691-126 is RoHS non-compliant. For RoHS3 compliance, select from: TE Connectivity 6-146252-3, 3M 929715-01-13-EU, Samtec BBD-113-G-B, Samtec MTSW-113-22-G-D-365, or any Sullins variant. For RoHS compliance (non-RoHS3), TE Connectivity 87215-9 is suitable. Verify your regulatory requirements before final part selection.

Q: What is the difference between board-to-board and board-to-cable style connectors?

A: Board-to-board connectors mate two PCBs directly. Board-to-cable connectors accommodate cable termination in addition to board mating. The 68691-126 is board-to-board only. Substitutes offering board-to-cable capability (TE Connectivity 6-146252-3, Samtec MTSW-113-22-G-D-365, and all Sullins variants) provide design flexibility for applications requiring either configuration.

Q: How does inventory availability affect my selection?

A: TE Connectivity 6-146252-3 offers the highest inventory (64520 units), followed by Samtec MTSW-113-22-G-D-365 (5916 units). Standard availability is 1000+ units for most Sullins variants. The original 68691-126 has 988 units in stock. For high-volume production, TE Connectivity 6-146252-3 provides the most reliable supply continuity.
