Substitute Part Grouping Explanation

Substitution eligibility for the B11B-PH-K-S is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Header with male pin contacts
Position Count & Pitch: 11 positions at 0.079" (2.00mm) mating pitch
Mounting & Termination: Through-hole mounting with press-fit/solder termination capability
Shrouding Design: Shrouded 4-wall construction
Material & Finish Specifications: Brass contacts with tin finish; PA66/Nylon 6/6 insulation
Environmental Compliance: UL94 V-0 flammability rating; ROHS3 compliance; MSL 1

The substitute part 1-440054-1 (TE Connectivity AMP Connectors) meets all critical substitution criteria across these parameters, enabling direct functional equivalence in board-to-cable/wire applications.

Engineering Selection Recommendations

Both the B11B-PH-K-S and 1-440054-1 are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. The substitute part 1-440054-1 demonstrates equivalent or superior electrical and mechanical performance across all critical parameters. The TE Connectivity part carries higher current (3A vs. 2A) and voltage (250V vs. 100V) ratings, providing additional design margin in applications where these specifications are relevant. Dimensional variations in contact length and insulation height are within negligible tolerances and do not affect mechanical or electrical compatibility. Both parts maintain identical operating temperature ranges, moisture sensitivity levels, and material compositions. Selection between these parts is determined by procurement availability, cost considerations, and application-specific electrical requirements.

Frequently Asked Questions (FAQ)

Q: Can 1-440054-1 be used as a direct replacement for B11B-PH-K-S in existing designs?

A: Yes. Both connectors share identical pitch (2.00mm), position count (11), mounting type (through-hole), shrouding design (4-wall), and termination methods (press-fit/solder). Dimensional tolerances are equivalent within engineering specifications.

Q: What are the key differences between these two connectors?

A: The primary differences are manufacturer (JST vs. TE Connectivity) and electrical ratings. The TE part (1-440054-1) is rated for 3A current and 250V voltage, compared to 2A and 100V for the JST part. Contact length dimensions vary by approximately 0.002" (0.05mm), which is negligible for standard PCB applications.

Q: Are both parts RoHS compliant?

A: Yes. Both B11B-PH-K-S and 1-440054-1 are ROHS3 compliant with UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels.

Q: What is the mating pitch for these connectors?

A: Both connectors operate at 0.079" (2.00mm) mating pitch, ensuring mechanical and electrical compatibility with corresponding receptacle connectors designed for this standard pitch.

Q: Can these connectors be used in automotive or medical applications?

A: The TE Connectivity part (1-440054-1) is documented for automotive, general purpose, industrial, and medical applications. The JST part (B11B-PH-K-S) does not specify application categories in the provided data. Application suitability should be confirmed against specific design requirements and relevant industry standards.

Q: What termination methods are supported?

A: Both connectors support press-fit and solder termination, providing flexibility for automated assembly or manual soldering processes.
