Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the B4B-PH-K-S are qualified based on the following core parameters that determine functional compatibility:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 4
• Number of Rows: 1
• Mounting Type: Through Hole
• Style: Board to Cable/Wire
• Contact Material: Brass
• Insulation Material: Polyamide (PA66), Nylon 6/6
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core criteria. Variations in secondary parameters such as shrouding configuration, contact shape, termination method, and electrical ratings are documented in the comparison table to support engineering selection decisions.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current production status and meet UL94 V-0 flammability requirements. Selection among these alternatives depends on specific application requirements:

440054-4 (TE Connectivity HPI Series) provides the highest voltage rating at 250V and current rating at 3A, with press-fit termination matching the B4B-PH-K-S. This part is suitable for applications requiring enhanced electrical performance margins.

2SH-C-04-TS (Adam Tech) and SWR201-NRTN-S04-SA-WH (Sullins) maintain the 2A current rating specification of the original part. The 2SH-C-04-TS offers 4-wall shrouding identical to the B4B-PH-K-S with square contact geometry. The SWR201-NRTN-S04-SA-WH provides the highest inventory availability at 40,589 pieces.

292161-4 (TE Connectivity CT Series) features 3-wall shrouding and circular contact geometry, with voltage rating of 125VAC. This part is suitable for general-purpose applications where shrouding configuration differences are acceptable.

All parts comply with RoHS requirements and maintain MSL 1 (Unlimited) moisture sensitivity classification, ensuring compatibility with standard storage and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can I use 292161-4 as a direct replacement for B4B-PH-K-S?

A: The 292161-4 shares the core connector specifications (4-position, 2mm pitch, through-hole header) but differs in shrouding configuration (3-wall versus 4-wall) and contact shape (circular versus square). Functional compatibility depends on whether the application accommodates these mechanical differences and the higher mating contact length of 0.177" (4.50mm) versus 0.130" (3.30mm).

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

A: Press-fit termination (B4B-PH-K-S and 440054-4) uses a mechanical interference fit into plated through-holes. Kinked pin termination (292161-4, 2SH-C-04-TS, and SWR201-NRTN-S04-SA-WH) uses a bent lead design. Both are soldered to the PCB. Selection depends on PCB hole design and manufacturing process compatibility.

Q: Are there current rating limitations I should consider?

A: The B4B-PH-K-S is rated at 2A. The 440054-4 provides 3A rating, suitable for higher-current applications. The SWR201-NRTN-S04-SA-WH is rated at 1A per contact, which may be limiting for applications requiring the full 2A specification. The 292161-4 current rating varies by wire gauge and should be verified against specific application requirements.

Q: Does shrouding configuration affect compatibility?

A: Shrouding configuration (3-wall versus 4-wall) affects mechanical fit and mating interface geometry. The B4B-PH-K-S uses 4-wall shrouding. Substitute parts with different shrouding may require verification of mating connector compatibility and PCB layout accommodation.

Q: What is the significance of contact shape differences?

A: The B4B-PH-K-S uses square contacts, while the 292161-4 uses circular contacts. Contact shape affects contact resistance, mating force, and compatibility with specific mating connectors. Square and circular contacts are not interchangeable with the same mating connector designs.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are RoHS compliant (RoHS3 Compliant status). The B4B-PH-K-S is RoHS Compliant. All parts meet current regulatory requirements for restricted substance elimination.

Q: What is the inventory status of these parts?

A: B4B-PH-K-S: 5,300 pieces; 292161-4: 15,810 pieces; 2SH-C-04-TS: 2,562 pieces; 440054-4: 2,400 pieces; SWR201-NRTN-S04-SA-WH: 40,589 pieces. Inventory levels should be verified with suppliers for current availability.
