MTSW-102-05-G-S-225 Equivalent & Substitute Parts

Part Overview

The MTSW-102-05-G-S-225 is a rectangular connector header manufactured by Samtec Inc. within the Flex Stack MTSW series. This through-hole mounted connector features 2 positions at 0.100" (2.54mm) pitch with male pin contacts, gold-plated mating surfaces, and phosphor bronze contact material. The part is Active status and ROHS3 compliant. Substitute parts within this series are identified based on variations in contact post length and overall contact length, which determine board-to-board or cable integration requirements while maintaining electrical and mechanical compatibility across core connector specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MTSW-102-05-G-S-225 are qualified based on the following criteria:

Invariant Parameters (Must Match):

• Manufacturer: Samtec Inc.
• Series: Flex Stack, MTSW
• Base Product Number: MTSW-102
• Number of Positions: 2
• Pitch - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Contact Length - Mating: 0.225" (5.72mm)
• Insulation Height: 0.100" (2.54mm)
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Contact Finish Thickness - Mating: 10.0µin (0.25µm)
• Operating Temperature: -55°C ~ 125°C
• Current Rating: 3A
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Variable Parameters (Differentiate Substitutes):

• Contact Length - Post: Varies from 0.105" to 0.305"
• Overall Contact Length: Varies from 0.430" to 0.630"

The four substitute parts differ only in post length and overall contact length, accommodating different PCB thicknesses and stacking height requirements while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All five parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Selection between the MTSW-102-05-G-S-225 and its substitutes is determined by post length requirements for specific PCB thickness and stacking height applications:

• MTSW-102-07-G-S-225: Shortest post length (0.105"), suitable for minimal stacking height applications
• MTSW-102-23-G-S-225: Short post length (0.120"), accommodates thin PCB assemblies
• MTSW-102-24-G-S-225: Medium post length (0.155"), standard mid-range stacking requirement
• MTSW-102-22-G-S-225: Longest post length (0.305"), accommodates thicker PCB or extended stacking configurations

All substitute parts carry identical electrical ratings, contact materials, finish specifications, and temperature operating ranges, ensuring direct functional interchangeability within the specified mechanical envelope.

Frequently Asked Questions (FAQ)

Q: Can MTSW-102-05-G-S-225 be directly replaced with any of the substitute parts?

A: Direct replacement depends on PCB thickness and available stacking height. All substitute parts share identical electrical specifications, contact materials, and mating characteristics. The primary difference is post length, which determines how far the solder posts extend below the PCB. Verify your design's mechanical clearance requirements before substitution.

Q: What determines the choice between MTSW-102-07-G-S-225, MTSW-102-23-G-S-225, MTSW-102-24-G-S-225, and MTSW-102-22-G-S-225?

A: Post length selection is driven by PCB thickness and available space below the board. MTSW-102-07-G-S-225 has the shortest post (0.105"), while MTSW-102-22-G-S-225 has the longest (0.305"). Choose based on your specific board assembly requirements.

Q: Are all parts in this family electrically identical?

A: Yes. All parts maintain 3A current rating, -55°C to 125°C operating temperature, identical contact materials (phosphor bronze), gold plating specifications, and UL94 V-0 flammability rating. Electrical performance is equivalent across all variants.

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

A: Contact post length determines the solder tail extension below the PCB surface. This parameter is critical for through-hole soldering depth, wave soldering compatibility, and clearance to components on the opposite side of the board.

Q: Are packaging differences between these parts significant for substitution?

A: The main part (MTSW-102-05-G-S-225) is packaged individually, while all substitute parts are supplied in bulk packaging. This affects order quantities and handling but does not impact electrical or mechanical compatibility.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant and carry UL94 V-0 material flammability rating. Moisture sensitivity level differs only for the main part (MSL 1, Unlimited) versus substitutes (Not Applicable), reflecting packaging and storage differences rather than component performance.
