Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S11B-PH-K-S is determined by the following critical parameters:

• Connector Configuration: 11 positions, 2.00mm pitch, through-hole right-angle header with male pins
• Electrical Specifications: Current and voltage ratings must meet or exceed 2A and 100V respectively
• Mechanical Compatibility: Shrouded design with detent lock fastening for board-to-cable/wire applications
• Termination Method: Press-fit solder capability for PCB assembly
• Environmental Compliance: UL94 V-0 flammability rating and RoHS compliance required
• Operating Range: -25°C to 85°C temperature specification

The two substitute parts identified (1-292253-1 and 1-440055-1) share the core functional requirements of 11-position, 2.00mm pitch rectangular connectors with through-hole right-angle mounting and detent lock fastening. Both are manufactured by TE Connectivity AMP Connectors and maintain active product status with equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status and meet the core functional requirements of the S11B-PH-K-S. Selection between alternatives should be based on the following criteria:

1-440055-1 (TE Connectivity HPI Series) is the preferred substitute when electrical margin is required. This part exceeds the original specifications with 3A current rating and 250V voltage rating compared to the S11B-PH-K-S 2A/100V ratings. It maintains identical press-fit solder termination, square contact geometry, and operating temperature range (-25°C to 85°C). Both parts carry UL94 V-0 flammability certification and RoHS3 compliance. The HPI series provides higher performance headroom for applications requiring enhanced electrical capacity.

1-292253-1 (TE Connectivity CT Series) is suitable for applications where electrical specifications are not limiting factors. This part features kinked pin termination instead of press-fit, which may require PCB design modification. The CT series uses circular contact geometry and 3-wall shrouding compared to the original 4-wall design. Current rating varies by wire gauge, and voltage rating is specified as 125VAC. This part maintains UL94 V-0 and RoHS3 compliance but does not specify operating temperature range.

Both substitute parts are manufactured by TE Connectivity AMP Connectors, a qualified supplier with established supply chain presence. All three connectors share identical 11-position, 2.00mm pitch configuration and through-hole right-angle mounting, ensuring mechanical compatibility with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can 1-440055-1 be used as a direct replacement for S11B-PH-K-S without PCB modification?

A: Yes. The 1-440055-1 maintains identical press-fit solder termination, square contact geometry, and contact post length (0.134" / 3.40mm) as the original part. Both connectors feature 11 positions at 2.00mm pitch with through-hole right-angle mounting. No PCB design changes are required for this substitution.

Q: What are the key differences between 1-292253-1 and 1-440055-1?

A: The primary differences are termination method (kinked pin vs. press-fit), contact geometry (circular vs. square), shrouding design (3-wall vs. 3-wall), and electrical ratings. The 1-292253-1 uses kinked pin termination, which requires different PCB hole design compared to press-fit. The 1-440055-1 maintains press-fit compatibility with the original S11B-PH-K-S design.

Q: Does 1-292253-1 require PCB redesign?

A: Yes. The kinked pin termination of 1-292253-1 differs from the press-fit design of S11B-PH-K-S. PCB hole sizing and plating specifications must be verified for compatibility with kinked pin termination. Additionally, the contact post length (0.126" / 3.20mm) is shorter than the original (0.134" / 3.40mm), which may affect solder joint formation depending on PCB thickness.

Q: Are all three connectors RoHS compliant?

A: Yes. The S11B-PH-K-S is RoHS Compliant. Both substitute parts (1-292253-1 and 1-440055-1) are ROHS3 Compliant, which represents an updated compliance standard. All three parts meet RoHS requirements for restricted substance elimination.

Q: What is the operating temperature range for 1-292253-1?

A: The operating temperature range is not specified in the available technical data for 1-292253-1. The S11B-PH-K-S and 1-440055-1 both specify -25°C to 85°C. Verify operating temperature requirements with the manufacturer if this specification is critical for your application.

Q: Can these connectors be used interchangeably in the same assembly?

A: Mechanical and electrical interchangeability depends on termination method compatibility. The 1-440055-1 is directly interchangeable with S11B-PH-K-S due to identical press-fit termination. The 1-292253-1 requires PCB design verification due to kinked pin termination differences. All three connectors share identical 11-position, 2.00mm pitch configuration and detent lock fastening (where specified).

Q: What is the difference in shrouding between these parts?

A: The S11B-PH-K-S features 4-wall shrouding, while both substitute parts (1-292253-1 and 1-440055-1) feature 3-wall shrouding. This difference affects mechanical protection and mating interface design. Verify that mating connectors are compatible with 3-wall shrouding if substituting from the original 4-wall design.
