Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B6B-PH-K is determined by the following critical parameters:

• Mating Pitch: 0.079" (2.00mm) — must match exactly for mechanical and electrical compatibility
• Number of Positions: 6 positions — required for circuit board layout compatibility
• Connector Type: Header with male pin contacts — functional requirement for mating interface
• Mounting Type: Through hole — PCB assembly process compatibility
• Shrouding Configuration: 4-wall shrouding provides mechanical alignment and polarization
• Contact Material and Finish: Brass with tin finish — electrical conductivity and corrosion resistance
• Insulation Material: Polyamide (PA66), Nylon 6/6 — thermal and chemical stability
• Flammability Rating: UL94 V-0 — safety compliance requirement
• RoHS Compliance: Required for regulatory adherence

The three substitute parts identified (292161-6, 440054-6, and SWR201-NRTN-S06-SA-WH) share the core mating pitch, position count, connector type, and mounting method. Variations in shrouding design (3-wall vs. 4-wall), termination method (kinked pin vs. press-fit), contact geometry (circular vs. square), and electrical ratings are documented in the parameter comparison table to enable informed selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All four connectors maintain active product status with full RoHS3 compliance and MSL 1 rating, ensuring regulatory adherence and long-term availability.

B6B-PH-K (JST Sales America Inc.) — Primary specification. 4-wall shrouding with press-fit and solder termination. Square contact geometry. 2A current rating at 100V. Operating temperature range -25°C to 85°C. Suitable for general-purpose through-hole applications requiring standard electrical performance.

440054-6 (TE Connectivity HPI Series) — Highest electrical rating among substitutes. 3A current rating at 250V. 4-wall shrouding with press-fit and solder termination. Square contact geometry matching B6B-PH-K. Overall contact length 0.335" (8.51mm) and insulation height 0.238" (6.05mm) closely align with primary part. Operating temperature -25°C to 85°C. Suitable for applications requiring elevated voltage or current capacity. Contact finish thickness specified at 80.0µin (2.03µm).

292161-6 (TE Connectivity CT Series) — 3-wall shrouding configuration differs from primary part. Kinked pin termination instead of press-fit. Circular contact geometry. Current rating varies by wire gauge; voltage rating 125VAC. Overall contact length 0.370" (9.40mm) and insulation height 0.268" (6.80mm) represent dimensional variations. Operating temperature not specified. Suitable for applications where 3-wall shrouding and kinked pin termination are acceptable.

SWR201-NRTN-S06-SA-WH (Sullins Connector Solutions) — 4-wall shrouding with kinked pin and solder termination. Square contact geometry. 1A per contact current rating at 125V. Contact length - post 0.134" (3.40mm) and insulation height 0.236" (6.00mm) match primary part. Operating temperature -25°C to 85°C. Suitable for lower-current applications where kinked pin termination is preferred. White insulation color provides visual differentiation.

Frequently Asked Questions (FAQ)

Q: Can 292161-6 directly replace B6B-PH-K in existing designs?

A: 292161-6 shares the critical mating pitch (2.00mm) and 6-position configuration but differs in shrouding design (3-wall vs. 4-wall), contact geometry (circular vs. square), and termination method (kinked pin vs. press-fit). PCB footprint compatibility requires verification. The 3-wall shrouding may affect mechanical alignment and polarization. Electrical ratings differ: 292161-6 current varies by wire gauge versus B6B-PH-K's fixed 2A rating.

Q: What are the electrical differences between these connectors?

A: B6B-PH-K operates at 2A/100V. 440054-6 provides the highest rating at 3A/250V, suitable for higher-power applications. 292161-6 current rating varies by wire gauge at 125VAC. SWR201-NRTN-S06-SA-WH is rated 1A per contact at 125V, suitable for lower-current circuits. Operating temperature specifications are -25°C to 85°C for B6B-PH-K, 440054-6, and SWR201-NRTN-S06-SA-WH; 292161-6 does not specify operating temperature.

Q: Are all substitutes RoHS compliant?

A: Yes. B6B-PH-K is RoHS Compliant. 292161-6, 440054-6, and SWR201-NRTN-S06-SA-WH are all ROHS3 Compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between press-fit and kinked pin termination?

A: Press-fit termination (B6B-PH-K, 440054-6) uses a straight pin inserted into plated through-holes under controlled force, providing consistent contact pressure. Kinked pin termination (292161-6, SWR201-NRTN-S06-SA-WH) features a bent pin that anchors mechanically during insertion. Press-fit typically offers superior contact reliability; kinked pin provides alternative assembly compatibility.

Q: Does shrouding configuration affect PCB layout?

A: Yes. 4-wall shrouding (B6B-PH-K, 440054-6, SWR201-NRTN-S06-SA-WH) provides full perimeter guidance and polarization. 3-wall shrouding (292161-6) omits one wall, reducing mechanical constraint. PCB footprint dimensions and mounting hole patterns must be verified for compatibility. Insulation height variations (6.00mm to 6.80mm) may affect board-to-board spacing in stacked configurations.

Q: Which substitute offers the best electrical performance?

A: 440054-6 provides the highest electrical ratings at 3A/250V with operating temperature range -25°C to 85°C, matching the primary part's temperature specification. Contact finish thickness is specified at 80.0µin (2.03µm). This part is suitable for applications requiring elevated voltage or current capacity while maintaining dimensional compatibility with B6B-PH-K.

Q: Can contact shape differences (square vs. circular) affect performance?

A: Contact shape affects contact pressure distribution and insertion force characteristics. Square contacts (B6B-PH-K, 440054-6, SWR201-NRTN-S06-SA-WH) provide consistent contact geometry. Circular contacts (292161-6) distribute force differently. Both geometries are acceptable for standard applications; selection depends on mating connector design and insertion force requirements.
