MTSW-102-09-G-S-009 Equivalent & Substitute Parts

Part Overview

The MTSW-102-09-G-S-009 is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 2-position, 0.100" (2.54mm) pitch connector operates across -55°C to 125°C and carries a 3A current rating. The part is active in production status and fully RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling component interchangeability in board-level applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-102-09-G-S-009 is determined by the following critical parameters:

• Connector Type & Configuration: Header format with through-hole mounting capability
• Electrical Interface: 2-position, 0.100" (2.54mm) pitch mating interface
• Contact Specification: Male pin contact type with solder termination
• Current & Temperature Ratings: Minimum 3A current capacity and operating range encompassing -55°C to 125°C
• Compliance & Safety: UL94 V-0 flammability rating and RoHS3 compliance

The substitute part PEC02SFAN meets these criteria with equivalent position count, pitch, contact type, mounting method, current rating, and regulatory compliance. Variations in contact finish material (gold vs. tin), contact geometry, and insulation material do not preclude substitution when the primary electrical and mechanical interface parameters remain compatible.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSW-102-09-G-S-009 and PEC02SFAN are active production parts with full RoHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

MTSW-102-09-G-S-009 (Samtec): Choose when gold-plated mating contacts are specified for enhanced corrosion resistance or when the cuttable header feature is required for custom breakaway configurations.

PEC02SFAN (Sullins): Choose when tin-plated contacts are acceptable and the breakaway header format meets application requirements. This part offers an extended lower operating temperature limit (-65°C vs. -55°C).

Both parts satisfy identical electrical interface requirements, current ratings, and regulatory compliance standards. Physical differences in contact geometry and insulation material do not affect board-level interchangeability when mating with standard 0.100" (2.54mm) pitch connectors.

Frequently Asked Questions (FAQ)

Q: Can PEC02SFAN directly replace MTSW-102-09-G-S-009 in existing designs?

A: Yes. Both parts share identical 2-position, 0.100" (2.54mm) pitch male pin headers with through-hole solder mounting, 3A current rating, and UL94 V-0 compliance. The primary differences are contact finish material and insulation polymer, which do not affect mating compatibility with standard 0.100" (2.54mm) pitch receptacles.

Q: What is the significance of the contact finish difference (gold vs. tin)?

A: Gold plating on the MTSW-102-09-G-S-009 provides superior corrosion resistance and lower contact resistance over extended service life. Tin plating on the PEC02SFAN is suitable for standard industrial applications with adequate environmental protection. Selection depends on application-specific reliability and environmental requirements.

Q: Are there temperature rating implications for substitution?

A: The PEC02SFAN operates to -65°C, providing a 10°C lower minimum temperature capability compared to the MTSW-102-09-G-S-009 at -55°C. Both parts support the same maximum temperature of 125°C. For applications requiring operation below -55°C, the PEC02SFAN is the appropriate choice.

Q: What does "cuttable" vs. "breakaway" mean for these headers?

A: Both terms describe the ability to separate individual positions from the connector strip. Cuttable headers (MTSW series) are cut with a blade or saw, while breakaway headers (PEC02 series) are designed to snap apart at predetermined break points. Both configurations result in single-position connectors suitable for custom applications.

Q: Are both parts suitable for automated assembly?

A: Yes. Both parts are through-hole solder termination connectors compatible with standard wave soldering and selective soldering processes used in automated PCB assembly.
