Key Parameters

Substitute Part Grouping Explanation

Substitution for the S7B-PH-SM3-TB is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Position Count & Pitch: 7 positions at 0.079" (2.00mm) mating pitch
• Mounting & Orientation: Surface mount, right-angle configuration
• Shrouding: 4-wall shrouded design
• Termination Method: Solder termination with detent lock fastening
• Contact Material & Finish: Brass contacts with tin or tin-lead finish
• Insulation Material: Polyamide-based (PA46, PA9T, or PA6T variants acceptable)
• Electrical Ratings: Voltage and current ratings must meet or exceed 100V and 2A respectively
• Environmental Compliance: UL94 V-0 flammability rating

The following parts meet these substitution criteria and are functionally equivalent for board-to-cable/wire applications:

1. 1775469-7 (TE Connectivity) – Active status, higher electrical ratings
2. 2-292173-7 (TE Connectivity) – Active status, CT series
3. 292173-7 (TE Connectivity) – Active status, CT series, highest inventory availability
4. SWR201-NRTN-S07-HM-BG (Sullins Connector Solutions) – Active status, SWR201 series

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 292173-7 (TE Connectivity)

The 292173-7 offers the highest inventory availability (14,220 pcs) and active product status. It maintains full mechanical and electrical compatibility with the S7B-PH-SM3-TB, including identical pitch, position count, mounting configuration, and shrouding. The part is RoHS compliant and carries UL94 V-0 flammability certification. The CT series design includes board guide features for enhanced assembly reliability.

Secondary Recommendation: 1775469-7 (TE Connectivity)

The 1775469-7 provides superior electrical ratings (3A current, 250V voltage) and is ROHS3 compliant. This part is suitable for applications requiring higher performance margins. The HPI series construction offers enhanced reliability for automotive, industrial, and medical applications.

Alternative: 2-292173-7 (TE Connectivity)

The 2-292173-7 is functionally equivalent to 292173-7 with identical electrical and mechanical specifications. Both are CT series parts with active status and RoHS3 compliance. Selection between these two depends on packaging preference (Tape & Reel) and inventory availability.

Alternative: SWR201-NRTN-S07-HM-BG (Sullins Connector Solutions)

The SWR201-NRTN-S07-HM-BG maintains full mechanical compatibility and is ROHS3 compliant. Current rating is specified at 1A per contact, which is lower than the original part. This option is suitable for lower-power applications and offers an alternative supplier source.

Frequently Asked Questions (FAQ)

Q: Can I use 1775469-7 as a direct replacement for S7B-PH-SM3-TB?

A: Yes. The 1775469-7 maintains identical mating pitch (2.00mm), position count (7), mounting type (surface mount right-angle), shrouding (4-wall), and termination method (solder). Electrical ratings exceed the original specification. The part is active and RoHS3 compliant.

Q: What is the difference between 292173-7 and 2-292173-7?

A: Both parts are CT series connectors with identical electrical and mechanical specifications. The primary difference is the base product number designation. Both are active, RoHS3 compliant, and suitable for direct substitution.

Q: Does the insulation material change affect compatibility?

A: The substitute parts use PA9T or PA6T polyamide variants instead of PA46. All variants meet UL94 V-0 flammability requirements and maintain the same operating temperature range (-25°C ~ 85°C). These materials are functionally equivalent for the specified application.

Q: Why is the current rating lower for SWR201-NRTN-S07-HM-BG?

A: The SWR201-NRTN-S07-HM-BG is rated at 1A per contact, compared to 2A for the original part. This part is suitable for applications with lower current requirements. For applications requiring 2A or higher current capacity, use 292173-7, 2-292173-7, or 1775469-7.

Q: Are all substitute parts RoHS compliant?

A: The original S7B-PH-SM3-TB is RoHS non-compliant. All substitute parts (1775469-7, 2-292173-7, 292173-7, and SWR201-NRTN-S07-HM-BG) are RoHS3 compliant, making them suitable for applications with RoHS requirements.

Q: What packaging options are available?

A: The S7B-PH-SM3-TB original packaging is not specified. Substitute parts are available in Tape & Reel (TR) packaging for 1775469-7, 2-292173-7, and 292173-7, and Tube packaging for SWR201-NRTN-S07-HM-BG.

Q: Can I mix substitute parts in the same design?

A: Yes. All substitute parts maintain identical mating pitch, position count, and mechanical configuration. They are interchangeable at the board level. Ensure your application requirements are met by the selected part's electrical ratings.
