MTSW-136-08-T-S-295 Equivalent & Substitute Parts

Part Overview

The MTSW-136-08-T-S-295 is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 36-position, single-row connector operates at 0.100" (2.54mm) pitch and supports 3A current rating across an operating temperature range of -55°C to 105°C. The connector features a cuttable design within the Flex Stack series, enabling flexible board-to-board or cable interconnection. With active product status and ROHS3 compliance, this component remains in production with 781 units currently in stock. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate alternative connector configurations.

Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-136-08-T-S-295 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Contact Type: Male Pin — exact match required
• Mounting Type: Through Hole — exact match required
• Termination: Solder — exact match required
• Material Flammability Rating: UL94 V-0 — minimum compliance required
• RoHS Status: ROHS3 Compliant — regulatory compliance required

Secondary Compatibility Parameters:

• Connector Type: Header variants (cuttable, breakaway) acceptable
• Style: Board to Board or Cable — functional equivalence
• Contact Finish: Tin or Gold acceptable for mating surface
• Insulation Material: Polyester or Polyamide variants acceptable

The substitute part 0022284036 (Molex KK254 series) meets the core substitution criteria through matching pitch, contact type, mounting method, termination type, flammability rating, and RoHS compliance. However, this part is configured as a 3-position connector, requiring design-level evaluation for position count compatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSW-136-08-T-S-295 and 0022284036 maintain active product status with ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory alignment for current and future applications. The primary distinction between these connectors is position count: the Samtec part provides 36 positions while the Molex substitute provides 3 positions. Selection between these parts depends on the specific position requirements of the target application. The Molex 0022284036 is suitable for applications requiring 3-position connectivity at 2.54mm pitch with identical electrical and thermal specifications. The Samtec MTSW-136-08-T-S-295 remains the appropriate choice for applications requiring the full 36-position configuration. Both parts support identical current rating (3A), pitch (2.54mm), mounting method (through-hole solder), and contact type (male pin), establishing functional equivalence within their respective position configurations.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284036 directly replace the Samtec MTSW-136-08-T-S-295 in all applications?

A: Direct replacement is possible only in applications requiring 3-position connectivity. The Molex part is a 3-position connector while the Samtec part is a 36-position connector. Position count compatibility must be verified against the target application's circuit design before substitution.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: pitch (0.100" / 2.54mm), contact type (male pin), mounting method (through-hole), termination type (solder), flammability rating (UL94 V-0 minimum), and RoHS compliance status (ROHS3). Both parts meet these criteria.

Q: Are there dimensional differences between these connectors?

A: Yes. The Molex 0022284036 has slightly shorter contact lengths and insulation height compared to the Samtec MTSW-136-08-T-S-295. Mating contact length differs by 0.055" (1.39mm), post contact length by 0.010" (0.25mm), and insulation height by 0.010" (0.25mm). These differences may affect mechanical fit in space-constrained applications.

Q: What is the difference between "cuttable" and "breakaway" connector types?

A: Both connector types allow position reduction through mechanical separation. Cuttable connectors are cut to the desired length, while breakaway connectors feature pre-scored sections for breaking. Both achieve functional equivalence for applications requiring fewer positions than the full connector length.

Q: Are the contact finish specifications compatible?

A: Both parts use tin finish on the post (solder side). The mating surface differs: Samtec uses tin while Molex uses gold. Gold plating provides enhanced corrosion resistance and contact reliability, making the Molex part suitable for applications with higher reliability requirements or corrosive environments.

Q: Is operating temperature specification available for the Molex part?

A: Operating temperature is not specified in the Molex 0022284036 datasheet parameters provided. The Samtec part specifies -55°C to 105°C operation. Temperature range verification is required before substitution in applications with extreme temperature requirements.
