Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MTSW-122-08-T-S-295 are identified based on alignment of critical electrical and mechanical parameters that define functional compatibility. The primary substitution criteria are:

Pitch - Mating: 0.100" (2.54mm) — determines physical mating compatibility with receptacles and PCB layouts.

Contact Type: Male Pin — ensures proper mating interface.

Mounting Type: Through Hole — maintains PCB assembly compatibility.

Termination: Solder — ensures compatible soldering process.

Contact Finish: Tin on both mating and post surfaces — provides equivalent electrical conductivity and corrosion resistance.

Material Flammability Rating: UL94 V-0 — maintains safety compliance.

RoHS Status: ROHS3 Compliant — ensures regulatory alignment.

Moisture Sensitivity Level: 1 (Unlimited) — indicates equivalent handling and storage requirements.

The substitute part 0022284022 (Molex KK254 series) shares these core parameters with the MTSW-122-08-T-S-295. However, differences exist in position count, insulation material composition, and contact post length, which may affect application suitability depending on specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSW-122-08-T-S-295 and 0022284022 maintain active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment. Both parts carry UL94 V-0 flammability ratings and MSL 1 classification, indicating equivalent environmental handling requirements.

The primary distinction between these parts is position count: the MTSW-122-08-T-S-295 provides 22 positions in a single row, while the 0022284022 provides 2 positions. This difference fundamentally affects application scope. The Samtec part is suited for multi-signal applications requiring consolidated connector footprints, whereas the Molex part addresses applications with minimal signal requirements or modular connector strategies.

Secondary differences include insulation material composition (Polyester vs. Polyamide) and minor variations in contact post length (0.135" vs. 0.120") and insulation height (0.100" vs. 0.090"). These variations do not affect electrical performance but may influence PCB layout considerations and mechanical fit within specific enclosure designs.

Selection should be based on position count requirements and PCB layout constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 0022284022 directly replace the MTSW-122-08-T-S-295 in existing designs?

A: Direct replacement is not possible due to the significant difference in position count (2 vs. 22). The 0022284022 is suitable only for applications requiring 2-position connectivity. For 22-position applications, the MTSW-122-08-T-S-295 remains the appropriate choice.

Q: Are the mating pitch specifications identical between these parts?

A: Yes. Both parts operate at 0.100" (2.54mm) pitch, ensuring compatibility with standard 2.54mm receptacles and PCB layouts designed for this spacing.

Q: What is the significance of the contact post length difference?

A: The MTSW-122-08-T-S-295 has a contact post length of 0.135" (3.43mm), while the 0022284022 has 0.120" (3.05mm). This 0.015" difference may affect solder joint formation and mechanical stability in applications with specific PCB thickness or assembly process parameters. Verify compatibility with your PCB thickness and soldering profile.

Q: Do both parts meet the same flammability and RoHS standards?

A: Yes. Both parts are UL94 V-0 rated and ROHS3 compliant, meeting equivalent safety and environmental regulatory requirements.

Q: What is the difference between "Cuttable" and "Breakaway" connector types?

A: The MTSW-122-08-T-S-295 features a cuttable design, allowing individual positions to be separated by cutting. The 0022284022 features a breakaway design, allowing positions to be separated by breaking. Both designs provide modularity, but the separation method differs.

Q: Are the insulation materials functionally equivalent?

A: Both materials (Polyester and Polyamide, both glass-filled) provide UL94 V-0 flammability performance and MSL 1 moisture sensitivity. Material selection may influence thermal performance and chemical resistance in specific environments, but both are suitable for standard industrial applications.
