TSW-122-07-T-S Equivalent & Substitute Parts

Part Overview

The TSW-122-07-T-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 22-position, single-row header operates at 0.100" (2.54mm) pitch and features unshrouded, solder-terminated male pins with tin-plated phosphor bronze contacts. The connector is classified as Active product status and complies with RoHS3 and UL94 V-0 flammability standards. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct functional replacement in board-to-board or cable applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-122-07-T-S is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Connector Type: Header with male pin contact type
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze or equivalent copper alloy
• Contact Finish: Tin-plated
• Insulation Material: Polybutylene Terephthalate (PBT) or thermoplastic equivalent
• Operating Temperature Range: Minimum -55°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 Compliant

The substitute part 4-103327-9 shares the core electrical and mechanical characteristics required for functional equivalence, including identical pitch, through-hole solder termination, push-pull fastening, and matching flammability and RoHS certifications. Variations in position count, contact post length, and insulation height do not preclude substitution when the application accommodates the physical differences.

Parameter Comparison

Engineering Selection Recommendations

The TSW-122-07-T-S maintains Active product status with full RoHS3 compliance and UL94 V-0 flammability certification, making it the preferred choice for new designs and applications requiring long-term component availability.

The substitute part 4-103327-9 is classified as Obsolete. While it shares critical electrical and mechanical parameters including 0.100" (2.54mm) pitch, through-hole solder termination, push-pull fastening, tin-plated contacts, and matching flammability and RoHS certifications, its obsolete status limits suitability to legacy system maintenance or applications where component availability is not a constraint.

Selection between these parts depends on application requirements: the main part is suitable for current production and new designs, while the substitute is applicable only when supporting existing systems already utilizing the 4-103327-9 connector or when position count and physical dimensions align with application constraints.

Frequently Asked Questions (FAQ)

Q: Can the 4-103327-9 directly replace the TSW-122-07-T-S in new designs?

A: No. The TSW-122-07-T-S is Active product status with guaranteed availability, while the 4-103327-9 is Obsolete. New designs should specify the TSW-122-07-T-S to ensure long-term component supply and support.

Q: What are the key differences between these connectors?

A: The main differences are position count (22 vs. 40), contact post length (0.100" vs. 0.120"), overall contact length (0.430" vs. 0.440"), and insulation height (0.100" vs. 0.090"). Both share identical 0.100" (2.54mm) pitch, through-hole solder termination, and push-pull fastening. Contact material differs (phosphor bronze vs. copper alloy) and insulation material differs (PBT vs. thermoplastic).

Q: Are the operating temperature ranges compatible?

A: Yes. The TSW-122-07-T-S operates -55°C ~ 105°C, while the 4-103327-9 operates -65°C ~ 105°C. The substitute part supports a wider low-temperature range, making it compatible for applications within the main part's temperature specification.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both are RoHS3 Compliant, UL94 V-0 rated, and classified as Moisture Sensitivity Level 1 (Unlimited). Both use tin-plated contacts and black insulation.

Q: What should be considered when evaluating position count differences?

A: The TSW-122-07-T-S provides 22 positions while the 4-103327-9 provides 40 positions. Substitution is only viable if the application can accommodate the larger connector footprint or if only a subset of positions is utilized. The breakaway feature of the 4-103327-9 allows position reduction through mechanical separation.

Q: Is the contact post length difference significant?

A: The contact post length differs by 0.020" (0.51mm). This variation may affect PCB trace routing and component placement. Verify that board design accommodates the 0.120" (3.05mm) post length of the substitute part.
