Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters:

• Connector Type & Contact Configuration: Header with male pins, 46 positions, 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting Technology: Surface mount solder termination
• Electrical Interface: Push-pull fastening, board-to-board or cable connectivity
• Environmental Compliance: UL94 V-0 flammability rating, MSL 1 classification

The substitute parts listed maintain these core specifications. Variations in contact finish thickness, insulation material (LCP vs. thermoplastic), contact material (phosphor bronze vs. copper alloy), and operating temperature ranges represent design alternatives within the same functional category. The Mill-Max 814-22-046-30-009101 uses spring piston contact technology instead of male pins, providing an alternative contact mechanism while maintaining 46-position, 2.54mm pitch compatibility. Samtec TSM series variants offer cuttable header designs with enhanced temperature ranges and material specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Samtec TSM Series - Active Status)

The Samtec TSM-123 series represents the most direct functional equivalents. All variants maintain the 46-position, 2.54mm pitch header configuration with surface mount solder termination. These parts are active products with ROHS3 compliance and extended operating temperature ranges (-55°C to 125°C), exceeding the original 3M specification. Selection among TSM variants depends on contact finish thickness requirements and packaging format:

• TSM-123-02-F-DV: Minimum gold finish thickness (3.00µin), bulk packaging
• TSM-123-02-G-DV: Medium gold finish thickness (10.0µin), gold post finish
• TSM-123-02-H-DV: Maximum gold finish thickness (30.0µin), gold post finish
• TSM-123-02-G-DV-A / TSM-123-02-F-DV-A: Tube packaging variants with board guide feature
• TSM-123-02-L-DV-A-P-TR / TSM-123-02-LM-DV-P-TR: Pick-and-place compatible variants

Alternative Contact Technology (Mill-Max 814-22-046-30-009101)

The Mill-Max 814-22-046-30-009101 provides a spring piston contact alternative maintaining 46-position, 2.54mm pitch compatibility. This part uses piston contact technology rather than male pins, offering different mechanical engagement characteristics. ROHS3 compliance and MSL 1 rating are maintained. This option is suitable for applications where piston contact engagement is acceptable or preferred.

Compliance Considerations

All active substitute parts carry ROHS3 compliance certification. The original 3M part does not specify RoHS status. For applications requiring RoHS compliance documentation, Samtec and Mill-Max alternatives provide certified compliance. All parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can Samtec TSM-123 series headers directly replace the 3M 961246-6700-AR-TP?

A: Yes. The TSM-123 series maintains identical 46-position, 2.54mm pitch, 2-row configuration with surface mount solder termination and push-pull fastening. The primary differences are extended operating temperature range (-55°C to 125°C vs. -25°C to 105°C), LCP insulation material, and phosphor bronze contact material. These represent design improvements compatible with the original application interface.

Q: What is the difference between TSM-123-02-F-DV and TSM-123-02-G-DV?

A: The primary difference is contact finish thickness. TSM-123-02-F-DV specifies 3.00µin (0.076µm) gold mating finish with tin post finish. TSM-123-02-G-DV specifies 10.0µin (0.25µm) gold mating finish with 3.00µin (0.076µm) gold post finish. TSM-123-02-H-DV provides the thickest gold finish at 30.0µin (0.76µm) mating with gold post finish. Selection depends on contact durability and mating cycle requirements.

Q: What packaging options are available for Samtec TSM-123 headers?

A: Bulk and tube packaging formats are available. Tube packaging variants (TSM-123-02-F-DV-A, TSM-123-02-G-DV-A) include board guide features. Pick-and-place compatible variants (TSM-123-02-L-DV-A-P-TR, TSM-123-02-LM-DV-P-TR) are available for automated assembly applications.

Q: Is the Mill-Max 814-22-046-30-009101 a direct pin-for-pin replacement?

A: The Mill-Max part maintains 46-position, 2.54mm pitch compatibility but uses spring piston contact technology instead of male pins. This represents an alternative contact mechanism. Mechanical engagement characteristics differ from the original header design. Compatibility depends on the mating connector type and application requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts (Samtec TSM series and Mill-Max 814-22-046-30-009101) carry ROHS3 compliance certification. The original 3M 961246-6700-AR-TP does not specify RoHS status.

Q: What is the difference between cuttable and non-cuttable header designs?

A: Samtec TSM-123 series headers are cuttable, allowing customization of position count after manufacturing. This feature does not affect the 46-position configuration when used as specified. The cuttable design provides manufacturing flexibility for applications requiring custom position counts.

Q: Do all substitute parts maintain the same current rating?

A: The original 3M part specifies 2A current rating. Samtec TSM-123 variants do not specify current rating in the provided data. Mill-Max 814-22-046-30-009101 does not specify current rating. For applications with specific current requirements, contact manufacturers for detailed electrical specifications.
